But I still can not find a way to use it when no Google internet connection available. After all, I'm a user from China, I can not access google directly.
The DNS is hardcoded to Google servers.

If you are rooted with Eureka-ROM, you can change the DNS.

But some applications still try to use Google DNS servers.

Now I'm looking for a workaround to get the image (both in portrait and landscape) to be displayed in horizontal, filling the entire screen and ignoring the fact that the actual position may be in portrait.
As far as I know the rotation follows the device.

Have you tried Rotation Lock Adaptive (Free) or Rotation Locker ?

I know it's opposite from what you want, but one of them got my normally-portrait applications showing up letterboxed on my landscape tablet, so it might work the opposite way on your portrait phone.

Filling the screen does require some scaling (and cropping if you want it to stay in the correct aspect ratio), so I'm not sure if that will work though.

Thanks! Well, I already tried another similar app (and now the one you suggested, just to be sure), and no luck.
When I rotate the phone (in auto mode) for a second the screen stays in the position I want (filling the screen, rotated 90° on the left but still in portrait) and it looks fine (if it just wouldn't switch to landscape right after), so I think that it would'nt require any scaling (if the screen is 16:9).

Since I'm not confident in my english I attach a poor edited jpg to give an idea of what I want to achieve (obviously I got the wrong aspect ratio and actually had to apply black bands at the borders :D)

I see what you want to do now... Hmm. I'm not sure how you would do it, since I believe Chromecast "thinks" it is natively landscape or Google Play services "knows" it is landscape.
It's an interesting puzzle.

Indeed! The easy way would be to have the developers of the apps to add an option for landscape mode with the layout just rotated and not adapted. But I doubt that they would do that just for me :D
As I was saying before once the chromecast reacted this way. It was right after the last big update which extended the mirroring to all device.. maybe it was just a bug, but in that moment I got the idea I'm now trying to elaborate.

This is not my area of expertise but, since when you rotate the phone (mirroring already on) before the image reshapes (on the phone) there is one second delay, and this delay is displayed in the very same way on the tv, I suppose that the chromecast mirrors the exact image asking separately for the orientation (maybe play services as you said). This is where my supposition has to stop.
If anyone can provide some suggestion I would be happy to hear and try.
By the way I'm not rooted, I was waiting for lollipop.

What do you mean chromecast app does not work ?? You dont see ur chromecast in the app ?? Are you able to change backdrop etc ??

chromecast app is working, but when i'm connecting, i can't connect to TV, it will just connect then after a few second, it will disconnect, but when using other application like any cast+, all cast & others, the casting is working, but when using the official chromecast app, the casting won't work.... :(

Try clearing the google play services cache: Go into settings, apps, all apps, google play services, clear cache.

i try this but still, no luck, i guess it's on the ROM or something is missing in the system..... :confused:

Are you talking about screen casting ?? You cannot connect to TV using chromecast App !! Chromecast app is used to connect with your chromecast, to reboot the chromecast, to check offers on your chromecast, to set guest mode on-off, to change backdrop !!

I think you are referring to screen cast option on your chromecast app on your tablet !! However screen casting never worked for me on this tablet !!

This is the behavior I see if there is poor WiFi connection to Chromecast (try using the HDMI extender or a side port on the TV), but it can also be caused by incompatibility with the phone/tablet hardware or ROM.

i HAVE chromecast inserted at my HDTV, why would i try to screen cast without the hardware?? :confused:
the problem is, my tablet can't connect to it, but my brother smart phone xiaomi redmi 1s can connect properly
NVM, thanks for replying :good:, i think it has some problem with roms

but our modem is just about 2m distance on our tv, it's also on full signal, so i think the problem is on my rom, thanks for the help anyway :good:

You'd be surprised how much the television affects the wireless reception.
Try the speed4cast app to see if its connection speed is being limited by wireless signal. Speed4cast should report a reasonable down/up speed. If it doesn't, the wireless signal is being blocked by the television proximity.

I just noticed I have SecondScreen from Braden Farmer in my Google Play wish list. Looks to have many options. Requires root (on your phone/tablet) though.

The DNS is hardcoded to Google servers.
If you are rooted with Eureka-ROM, you can change the DNS.
But some applications still try to use Google DNS servers.

Actually the Chromecast uses Google DNS as its preferred DNS, but if it can't reach Google DNS it falls back to the DNS supplied via DHCP from your router. You can change the DNS used by the Chromecast if you block access to Google DNS and supply a different one from your router or other DHCP server. Of course this is the opposite of the proper design. Who knows why Google chose to do that!

The one app that does its own non-standard things with the DNS is Netflix. Since last October Netflix has been experimenting with changes to how they handle the DNS, updating their app frequently. Unfortunately the Netflix Android app now fails to play content if it can't contact Google DNS, so if you are casting from Android and you have blocked Google DNS, you must select the Chromecast as the player before you attempt to play any content. Netflix claims that they are fooling around with the DNS to improve reliability, but if so then they have only managed to create a rather stupid bug that has reduced reliability. But it's widely believed that they are lying about that, and they are instead clumsily trying to block the use of alternative DNS services that allow region-changing.

hello,
when I stop streaming from my phone, the sound continues to be played on my speakers... Is there a way to stop the streaming directly with the phone ?

What app are you streaming from?

Connecting to Chromecast from a different app will have it load that app's player and stop whatever it's currently doing.

hello,
I'm using the Qobuz app to stream.
Maybe it's because the song is cached in the app and it continues streaming till the cache is empty.

It stops when I disconnect/reconnect the chromecast from the app.

Maybe it's more a problem from the Qobuz app than from the chromecast.

    PART 1
    1. General
      • What can I do with a Chromecast?
        Read Google's walkthrough, it's much better than the Chromecast product page. Also see Google's Chromecast app page. Here is a list of Chromecast-enabled apps on the Play store.

        Important to note here that Chromecast is not a "wireless replacement for a HDMI cable" in all cases. Save for screen-mirroring (coming), use of Chromecast requires that each individual application support it, unlike an HDMI cable which shows the device's entire screen.

        In this manner, Chromecast is more like an accessory that enhances applications that support it.
        One advantage Chromecast has over an HDMI cable is that it can run at full 1080p on the TV, whereas HDMI cable connections can be limited to device's screen resolution.

        Even though Chromecast is technically a standalone device, it's best to think of it as an extension of your tablet or phone's capabilities, rather than a full-fledged device.
      • How can Chromecast keep playing when I disconnect/shut down/reboot my phone/tablet/computer?
        Yes. See this post for more.
      • How is Chromecast different from Apple AirPlay?
        See this discussion.
      • Can I use Chromecast outside of the United States?
        As of March 19, 2014 Chromecast is now available in Canada and Europe.
        You can use Chromecast in other countries but without extra fiddling you will only have access to services available in your country. Region-aware services like YouTube, Netflix and Hulu will only show you content for your country.
        To view content from other countries will require using a DNS relocation service or VPN to get content from another region if the app is not supported in your region. @bagl0312 wrote a guide that should apply to most OpenWRT-based routers.
        See this discussion and Can I use a DNS other than Google? below.
        Also, allowed wireless channels vary outside of the US/Canada, so you might have to set your AP/router to a specific channel if it likes to auto-select one that Chromecast doesn't use.
      • How does Chromecast differ from using a TV output option on my phone/tablet/computer?
        The TV output of your phone/tablet/computer shows everything from your phone/tablet/computer, which can be quite nice. But, of course, the output on your TV is dependent on your phone/tablet/computer - you can't turn your phone/tablet/computer off an expect what's playing to continue playing on your TV.

        Chromecast, on the other hand, operates independently like a "second screen" type device. You send a request from your phone/tablet/computer to Chromecast and it goes and handle the request to play video, music, etc on its own. Unless you are streaming content stored on your phone/tablet/computer, your phone/tablet/computer is just used to monitor and control Chromecast. You can turn it off, or even have another device take over control. Your phone/tablet/computer is just the remote control for the Chromecast playback, and just like a TV remote control, the TV keeps playing if you take the remote away - you just can't control it. And Chromecast is wireless. :)

        If you have a spare Android device with WiFi and TV output, you can try using that as a Chromecast with [App] Cast Receiver app for Android or [App] YouMap Chromecast Receiver for Android
        (Below no longer works as of Cast SDK 2.0 release)
        If you have a spare Android device with WiFi and TV output, you can turn that into a Chromecast with Cheapcast.
        If you already happen to have a computer connected to your TV, you can use it as a Chromecast with the CR Cast extension or Leapcast for Google Chrome.

      • How does Chromecast differ from other media players like Roku and Apple TV?
        There's no remote. Your phone/computer/tablet is your remote. That means no more searching for the remote!
        While Chromecast may not have quite as wide a variety of content available, the the list of applications continues to grow.
      • I'm having trouble setting up my Chromecast with the app - is there a manual setup?
        Yes. Go here: https://cast.google.com/chromecast/setup?np=manualsetup
        Also check Google's Chromecast setup pages and Troubleshooter.
      • Any known issues with routers?
        Here's Google's Router Compatibility list. (The old Router Known Issues & Workarounds page seems to be no longer)
        At least one person needed to disable Parental Controls on their router. Access Control and Content Filtering do similar things so if you are having trouble, try toggling those options as well.
        Also, there are some WiFi Bandwidth and Router considerations to consider as well. Sustainable WiFi bandwidth is critical for a smooth casting experience.
        ISP-supplied Cisco DPC3825 seems not to allow Chromecast traffic between wired and wireless segments. See this post.
        If you suspect there is a bandwidth or router issue and have Netflix, you can try this diagnostic video
      • What control protocol does Chromecast use?
        Chromecast uses the DIAL protocol for discovery and casting.
      • Can I have more than one Chromecast on the same network?
        Yes. Available Chromecasts will appear in a list by name when you initiate the cast.
      • Can I cast to more than one Chromecast at the same time, from the same device?
        Yes, but only from different apps, for example, casting HBO GO to Chromecast #1 while casting YouTube to Chromecast #2.
      • My Chromecast came with a 3-month Netflix subscription code. I'm already a Netflix subscriber, can I use this?
        (Expired)
        Yes! And be sure to use it (or give it to a friend or family member) before December 31, 2013 because that's the date the code expires!
        jbl0ggs reports:
        According to Netflix rep, the 3-month Netflix code from the Chromecast promo, can be redeemed until 01/31/2014
        It'll add on to an existing subscription anyway, so don't delay!

      • My Chromecast came with a $6 Google Play Movies credit. What can I use that for?
        The credit applies to your Google Wallet, so you can use the credit for any content on the Google Play Store except for subscriptions. In other words, anything in Google Play Store with the exception of hardware and subscriptions.
        Be sure to redeem your code before March 31, 2014 because that's the date those codes expire, and the funds must be used by March 31, 2015.
      • What wireless type does Chromecast use?
        From the Play Store specifications Chromecast supports 2.4 GHz 802.11 b/g/n, though I really don't recommend trying it on an 802.11b network unless you have zero interference and minimal other usage.
      • What are the LED statuses for Chromecast?
        Blinking white - Chromecast is not connected to a WiFi access point, or it needs to be set up.
        * In current FlashCast, this means flashing is in progress.
        Solid white - Chromecast is connected to a WiFi access point. It may or may not be able to reach the Internet.
        * In older versions of FlashCast, this means flashing is in progress.
        Solid red - in the boot process (it should go white afterward), settings reset has been requested (by holding the button down)
        * In FlashCast, this means there was a problem flashing. Bad/missing eureka_image.zip or Chromecast may not be rootable.
      • Where is the Chromecast source? Known issues?
        Mirrored source
        Cast SDK issues
        Google Cast Release Notes
      • Can Chromecast control my TV?
        For automatic TV power-on and channel-switching, Chromecast uses HDMI-CEC. Most TVs with HDMI support CEC. Computer monitors, projectors and non-televisions generally do not support CEC.
        HDMI-CEC functionality is sometimes known by other names such as LG Simplink, Panasonic VIERA Link, Samsung Anynet+, Sony BRAVIA Sync. Your TV must have this feature enabled for the input Chromecast is connected to.
        In order for Chromecast to turn your TV on, it must be powered on - not all TVs provide USB power while switched off, so it is recommended to use wall power for Chromecast if you want it to be able to turn your TV on automatically.
        Chromecast does not turn the TV off.
      • Where is the Chromecast API or SDK?
        As of February 3, 2014, it is here!
      • Can I use a wired Ethernet connection with Chromecast for better bandwidth/performance?
        Yes, Google has released an Ethernet Adapter for Chromecast. The adapter is a combined power and OTG Ethernet adapter. The network plugs into the power "brick" which then has a long single cable that goes to the Chromecast. When using the Ethernet adapter you do *not* need to provide your wireless credentials to Chromecast. Unfortunately, because the Ethernet is hardwired to the OTG lines, you cannot use the official Ethernet adapter in conjunction with a powered OTG cable or USB storage. Some third-party USB Ethernet adapters should work if you want to easily switch out USB peripherals on rooted ROMs. Google "Chromecast OTG ethernet"
    2. Capabilities
      • What official apps and sites does Chromecast support?
        See Google's list of Chromecast apps.
        You can also check the Chromecast section of Google Play on your Android device for applications that support Chromecast. Store Home > Apps > Categories > Chromecast button at top
        Or you can check the list of Chromecast-enabled apps on the Play store.
      • What media types does Chromecast support?
        See Google's Supported media types page. Also, Avia notes that Chromecast has difficulty with media bit rates over 10 Mbps. @Asphyx recommends "Encode in H.264 Codec MP4. Keep the Video Bitrate lower than 4000."
        The author of BubbleUPnP has some great information regarding bandwidth and on-the-fly transcoding requirements and how it affects Chromecast streaming. The page is geared toward BubbleUPnP Server, but the information applies to all local-network Chromecast streaming applications.
      • Can I cast media stored on my phone/tablet?
        If media is in a format compatible with Chromecast...Transcoding allows a file that is not natively supported by Chromecast to be converted on-the-fly for playback on Chromecast.
      • Can I cast media stored on my computer?
      • Can I cast my computer's desktop?
        Yes, via the Cast extension for the Chrome browser. Note that there will be some lag between what you see on the computer and what you see on Chromecast as performance will depend greatly on your computer's processing power and your (home) network's bandwidth and latency. See this discussion for more.
      • Can I cast my phone/tablet's screen?
        Android screen mirroring to Chromecast was officially announced at Google I/O 2014 and went live July 9, 2014. It currently requires KitKat 4.4.1 or higher and a supported device, though see below...
        Supported devices at the moment are
        • Nexus 4
        • Google Nexus 5
        • Google Nexus 7 (2013)
        • Google Nexus 10
        • Samsung Galaxy S4
        • Samsung Galaxy S5
        • Samsung Galaxy Note 3
        • Samsung Galaxy Note 10 (2014)
        • HTC One M7
        • LG G Pro2
        • LG G2
        • LG G3
        The list is expected to grow, though the exact device limitations/requirements for screen casting are still not known.
        r3pwn has created an enabler to use screen mirroring on unsupported devices. Your mileage may vary, but worth checking out.

        The lag for screen mirror is minimal under ideal conditions

        If you can't get native mirroring for whatever reason, there is a pure software mirror called mirror4cast. It requires root and performance is nowhere near the native screen mirroring, but it does show what's on the Android display and works on devices running older Android versions.
      • Can I cast a browser tab?
        Yes, via the Cast extension for the Chrome browser
        1. with video?
          Yes, though playback performance will depend greatly on the source format of the video, your computer's processing power and your (home) network's bandwidth and latency.
        2. with full screen video?
          Yes, subject to above, just full-screen the video and it should appear full-screen on Chromecast as well. You can Alt-Tab (Windows) or Cmd-Tab (Mac OS) to let things play in the background while you do other tasks
      • Can I use my computer's speakers while casting to Chromecast?
        While casting, audio will be redirected to Chromecast, so audio will play out of your TV, not your PC. Besides, even if you got the PC speakers playing audio, it would be out of sync with the video on your TV because of compression/decompression and network transfer delay between your computer and Chromecast.
      • Can I use a DNS other than Google?
        By default Chromecast uses Google's DNS servers, regardless of what your DHCP-supplied DNS is.
        1. Stock
          You might be able to have Chromecast "fall back" to DHCP-supplied DNS by having your routerWhich one works will depend on your router's response. See this this thread
          If you have a more-intelligent router, you can set up iptables rules to intercept and re-route DNS requests to a different DNS server.
        2. Rooted
          Flashcast-AutoRoot lets you set the DNS in /data/dns.conf
          Eureka-ROM defaults to using the DHCP-supplied DNS servers, and includes presets for common DNS relocators, or you can set manually specify DNS IPs.
          If you are not using Eureka-ROM, there is a mod to use DHCP-supplied DNS. There are also mods to use the Unlocator DNS service and use the UnoTelly DNS service.
      • Can I specify what output resolution (480p, 720p, 1080i, 1080p, etc) Chromecast uses?
        Not at this time. You can specify streaming resolution for tab casting, but as far as actual output resolution, Chromecast appears to use the HDMI handshake to determine what it should output. This can potentially be a problem for displays that report 1080p support but do not correctly support 1080p input.
      • Can I use Chromecast on a public hotspot or hotel Wi-Fi?
        While Chromecast might connect to a public hotspot or hotel Wi-Fi network, most public hotspots and hotel Wi-Fi networks are configured to disallow connections between clients, which will prevent Chromecast from receiving cast requests and control from your tablet/phone/computer.
        Also, most of them require accepting some Terms of Service in a browser. Since Chromecast has no interface, you can't accept the terms. The same applies if the service requires a passcode or other authentication.
      • Do I need to have another device with WiFi in order to use Chromecast? Can't I just use it from a wired device on my network?
        Yes, at least for setup. Chromecast setup requires a supported Windows computer with WiFi, Mac OS computer with WiFi, Android device with WiFi, or iOS device with WiFi in order to set up Chromecast. This is because Chromecast acts as an access point during its setup process, so you need a WiFi-enabled device to connect to its access point to configure it. Once it is set up and connected to your wireless network, you can cast to Chromecast from both wired and wireless devices (assuming you're on the same subnet and wireless and wired networks are bridged, which is the default for most routers).
      • Casting my own media - which app is the best?
        It all depends on your needs and your media.
        @Asphyx posted a comprehensive comparison of the initial offerings.
        There are a number of offerings now including BubbleUPnP, Plex, Avia, RealPlayer Cloud, Localcast, etc. so it's probably best to do some searching and read feedback from other users to determine what's best for your case.
        Old information based on the initial offerings (Avia, Plex, RealPlayer Cloud) hidden below.

        Avia is better if...
        1. Your primary playback client is your Android phone/tablet
        2. All your media is in a Chromecast-compatible format, or you are willing to convert it to a Chromecast-compatible format
        3. You have a lot of media on your phone/tablet that you want to play and is Chromecast-compatible
        4. You have a DLNA server that is not a Plex server and you want to cast content from it
        5. You don't want to have a media server running (you don't have a server, or a system you're willing to have running for media playback)
        BubbleUPnP is better if...
        1. Your primary playback client is your Android phone/tablet
        2. All your media is in a Chromecast-compatible format, you are willing to convert it to a Chromecast-compatible format, or you are willing to run BubbleUPnP server
        3. You have a lot of media on your phone/tablet that you want to play and is Chromecast-compatible
        4. You have a DLNA server that is not a Plex server and you want to cast content from it
        5. You don't want to have a media server running (you don't have a server, or a system you're willing to have running for media playback), but you want the option to use one in the future (BubbleUPnP Server)
        Plex is better if...
        1. Your media is not in a Chromecast-compatible format or you have no idea what that means
        2. You have no clue what transcoding means, or you know what transcoding means, but you are unwilling to transcode your media library to make it Chromecast-compatible
        3. You are okay with running Plex Media Server on a system for media playback
        4. You have multiple playback devices (Roku, etc) that you use
        RealPlayer Cloud is better if...
        1. You need transcoding but are unwilling or unable to have a Plex Media Server in your network
        2. You want the convenience of having media on the RealPlayer Cloud
        3. You don't mind uploading non-Chromecast-compatible media to RealPlayer Cloud

    3. Connectivity
      • Can I connect Chromecast to...
        1. a computer monitor?
          Yes, in most cases, as long as the computer monitor supports video (as opposed to computer graphics) over HDMI or DVI.
          Note that connecting over DVI may not provide audio, so you may need an HDMI audio extractor device to "break out" the audio to go to speakers or an aux input.
        2. a HDTV with VGA?
          To be honest, it's probably cheaper and easier to upgrade your TV to one with HDMI.
          Yes, but it will require some kind of HDMI-to-VGA or HDMI-to-RGB converter, preferably one with audio output(s) like the HDfury2 or newer.
          If the converter does not have audio output(s), you will also need an HDMI audio extractor device to "break out" the audio to go to speakers or an aux input.
        3. a HDTV with analog component HD input?
          To be honest, it's probably cheaper and easier to upgrade your TV to one with HDMI.
          Yes, but it will require some kind of HDMI-to-Component converter, preferably one with audio output(s) like the HDfury2 or newer.
          If the converter does not have audio output(s), you will also need an HDMI audio extractor device to "break out" the audio to go to speakers or an aux input.
        4. a TV without HD inputs?
          To be honest, it's probably cheaper and easier to upgrade to an HDTV with HDMI.
          Yes, but it will require some kind of converter to convert HDMI to SD Component, S-Video or Composite video and audio.
          Unless your TV automatically handles widescreen input and the converter you choose sets the widescreen flag on output, make sure to get a converter that handles aspect ratio conversion (ARC, not to be confused with Audio Return Channel for HDMI, which is also ARC) as the Chromecast outputs 16:9 widescreen. Otherwise your Chromecast output will be horizontally squashed (people will be extra skinny).
          If the converter does not have audio output(s), you will also need an HDMI audio extractor device to "break out" the audio to go to speakers or an aux input. See this discussion.
        5. an UltraHD ("4K") TV?
          Sure. The TV will upscale the Chromecast output to the TV's native resolution.
      • How do I get audio from Chromecast out my...
        1. AV receiver?
          If your Chromecast is plugged into your AV receiver, it should pick up the audio automatically.
          If Chromecast is connected to your TV and both support ARC (Audio Return Channel), Chromecast's audio should be able to route through the HDMI cable connected between your TV and AV receiver.
          If Chromecast is connected to your TV and one or both do not support ARC, then you will need to take the audio output from your TV back to your AV receiver. TVs usually have a Digital output for this purpose, either coax SPDIF or optical TOSlink which you can take back to your receiver. If you TV's output and receiver's input don't match, you can get a Coax-to-Optical or Optical-to-Coax converter box.
          If Chromecast is connected to your TV, and one or both do not support ARC, and your TV does not have a digital audio output, then you will need to use analog audio, or get an HDMI audio extractor box to "break out" the audio from the HDMI stream so you can route it to your receiver.
        2. external sound bar or speakers?
          If your sound bar or speakers have HDMI input the information above about hooking up to an AV receiver applies.
          For other situations, you will need an HDMI audio extractor box to "break out" the audio from the HDMI stream so you can route it to your receiver as either a digital or analog signal.

    PART 2
    1. Root
      For additional root questions, please see the Root Mini-FAQ: What's the big deal with root? thread.
      • Which Chromecasts are rootable?
        A new root exploit was released on August 22, 2014. This exploit covers devices with builds older than 19084 (the exploit was patched in build 19084) and requires a Teensy 2.0 or 2++ development board along with a powered USB OTG cable and 1G+ flash drive. See this post for all the details!
        Old: Currently only devices with the original vulnerable bootloader (firmware build 12072) can be rooted.
        As newer Chromecasts are already shipping with newer firmware versions (and therefore no vulnerable bootloader), the serial number seems the most reliable way to tell whether an unused, unopened Chromecast can be rooted.
        Once set up, a stock Chromecast will automatically update its firmware (OTA updates from Google), so the serial number test is not valid for Chromecasts that have already connected to the Internet, unless you are very lucky and it has not yet downloaded or applied an update. See this discussion.

      • My Chromecast is supposed to be rootable, but it has already downloaded a Google OTA update. Can I still root it?
        A new root exploit was released on August 22, 2014. This exploit covers devices with newer bootloaders (12940-17977, perhaps newer), but requires a Teensy 2.0 or 2++ development board along with a powered USB OTG cable and 1G+ flash drive. See this post for all the details!
        Old: If Chromecast has not applied any OTA update, and you did not let it perform the update at boot, then you may be able to abort the update and still root it by opening it, jumping some pins and booting a FlashCast USB stick (it will delete the cached OTA update data). Not for the faint of heart! See this discussion.
        If your Chromecast has already applied any OTA update (your firmware build is no longer 12072), then no. Once an update is applied, the bootloader vulnerability is removed and you can no longer root with FlashCast.

      • How do I root?
        A new root exploit was released on August 22, 2014. This exploit covers devices with newer bootloaders (12940-17977, perhaps newer), but requires a Teensy 2.0 or 2++ development board along with a powered USB OTG cable and 1G+ flash drive. See this post for all the details!
        Old: You go from a stock Chromecast to a rooted Chromecast by using FlashCast to write a rooted firmware (like Eureka-ROM) by using the vulnerability in the original bootloader. The first time you use FlashCast you have to plug it into and boot it on Chromecast twice - first to prepare the FlashCast stick to accept mods, and the second time to flash a rooted, OTA-disabled firmware so you don't lose root.
        Read the Cliff notes version of the procedure, longer more-detailed version, or watch a video of the flashing/rooting process. For a flowchart and troubleshooting, see the Rooting with FlashCast Mini-FAQ.

      • What does root give me?
        ADB, Telnet, SSH, protection from Google OTA updates, ability to run unofficial apps (via Eureka-ROM), ability to change default behavior (like use a different DNS than Google) and the power to peek into the dark corners of your device. ;) See this discussion.
        1. Unofficial apps
          • Audiour - free audio sharing Info & Download
          • put.io - download torrents to cloud storage, rather than local
            See this post
          • AllCast (aka AirCast/KoushCast) old beta - stock Chromecasts should use released AllCast - send video stored on Android phone/tablet to Chromecast Download & Info
          • fling - send (Chromecast-compatible) video stored on computer to Chromecast Download & Info No longer works with Cast SDK 2.0
        2. Custom firmware (installing one of these is REQUIRED to preserve root!)
          • Flashcast-AutoRoot Keeps up-to-date with Google updates, automatically rooting on install. No extra features, but you can customize since you have root. Must install another rooted firmware like Eureka-ROM first! (See hidden below)
          • Eureka-ROM (KyoCast functionality and Use DHCP-provided DNS mods built-in, plus automatic Eureka-ROM OTA updates that upgrade while preserving root and a nifty web management panel)
            USB storage can be mounted via shell, see this thread.
          • Stock OS with updates disabled (to preserve root)[/url] no longer maintained, use Flashcast-AutoRoot
          • Rooted build 13300 (ADB and telnet enabled, OTA updates disabled)
          • PwnedCast - replaced by Eureka-ROM above. Existing PwnedCast installs will OTA upgrade to Eureka-ROM, unless you have disabled PwnedCast OTA updates.

        3. Mods (apply on top of rooted/custom firmware)
          • Use non-Google DNS (Unlocator, Unotelly, etc) - unnecessary for Eureka-ROM users who can specify DNS via the Eureka web panel
            For reference:
            Use DHCP-supplied DNS
            Use Unlocator DNS service.
            Use UnoTelly DNS service
          • Stock boot animation - switch back to the stock Chromecast boot animation when using custom firmware
          • rCast - use Chromecast as a standalone media player without an Internet connection (applies over Eureka-ROM, see the thread)
          • KyoCast (alternate whitelist) old - see below - run apps that have not been blessed by Google without being a developer.
            KyoCast is being phased out and its functionality is included in Eureka-ROM. For reference only, here is the original discussion on KyoCast

      • How can I check what firmware build my Chromecast has if I can't connect it to the Internet?
        Better instructions here.
        In order to use the Chromecast app to check the build, your Chromecast just needs to be connected to your WiFi, it doesn't need Internet. So, disconnect the WAN cable on your router. If you have an integrated modem/router, disconnect the DSL or Cable signal line to it - then nothing will connect to the Internet and you can safely check your Chromecast build from the app. If you have a spare AP or router, you can set up an isolated network and connect your phone/tablet/computer and Chromecast to it for setup.
        Don't forget to disconnect power on Chromecast before you reconnect the Internet!
        To be extra safe, perform a Factory Reset on it by holding down the button until the LED turns red. This will clear the Chromecast settings and it will prompt to be set up again.
      • I had root with Eureka-ROM and now it appears I don't?
        This can happen if the power is pulled or lost during an update.
        You may still have the vulnerable bootloader and be able to get root back, depending on how long it has been since the attempted update.
        Unplug Chromecast from power until you can re-flash the newest Eureka-ROM via OTG.
        This is a good reason to use AC/wall power rather than USB on the TV, as the TV often cuts USB power when the TV is turned off.
        For further details, see this post.
        Also, see note about rooting newer firmware version above.

    Let us know how it goes - I'm definitely curious as to whether your AVR can pull the audio without relying on the TV to send it back down. I can't really think of a technical reason it shouldn't be able to. The audio return is really meant for when the TV is doing on-board decoding, like when using an on-board QAM tuner.

    Using the CC with my AVR has turned out to be a great solution for me. Connecting the CC directly to my AVR allows me to listen to Google music without the TV on :D

    Root or not to root? I have a rootable one but don't have access to a computer at the moment thought. And I know there is some apps that I can use local files with and screen mirroring with but was there a way to root from a android terminal just curious or a imager app? Kinda wanna use this kinda been putting it off lol

    Hi, if you don't have access to a computer, but you have a powered USB OTG cable, you might be able to root it only with your phone, even without a flash drive.
    There is an app called Drivedroid which simulates a flash drive from your phone. Not every phone is supported, but I believe it works on most of them, it works on my old HD2 and on my 2012 Nexus 7 just fine. I haven't tested it, but you might be able to make your phone emulate the flashcast drive image and boot from that, and then root. This is just a theory, though. I don't know if DriveDroid supports the Flashcast image format. But there is no harm in trying.

    If you do not have a powered OTG cable or anything similar, you are unfortunately still out of luck.

    Post back if it worked.

    ---------- Post added at 01:56 PM ---------- Previous post was at 01:06 PM ----------

    Or, I thought of a way that could be much easier.

    If your phone is rooted and supports USB OTG, you can download the flashcast disk image and dd it from your phone to a flash drive. In Android Terminal Emulator type:
    Code:
    dd if=/path/to/downloaded/image.bin of=/path/to/flashdrive/device bs=1m
    Warning: this will DELETE EVERYTHING on your flash drive and there is no way to get it back. You have been warned.
    Also, if you are NOT 100% SURE with the path to your flash drive device, do not use this command, YOU COULD OVERWRITE SOMETHING IMPORTANT on your device and somehow damage it. In general, anything that begins /dev/block/mmc... is wrong, it is in the internal memory on the phone, not the flash drive. Really, be very careful. You have been warned.

    You should find out where is your flash drive device in the filesystem (NOT /usbdisk or /storage/usbdisk or similar, it is probably somewhere in /dev). On my tablet, it was on /dev/block/sda, but this can vary across devices. You can find out by looking into /dev/block with a file manager, first with the flash drive connected and then with the flash drive disconnected, and see what files are missing there.

    When you prepare your flash drive this way, you can continue with the flashcast guide.

    I just tested this on my Nexus 7 and it works well.
