Recently i also purchase the sony android TV and its performance is good.
Same here, but uptime is constantly high because of aud_cpupost.

Code:
BRAVIA_VH2:/ $ uptime

I read it here, but my English is pretty lousy, can anyone please tell me if I can root on the Sony Bravia XR-50X93J?
Thank you :)

See my 'BIG post' (page 85) with all paths we need to explore to finally root our Sony's!

Hi. I'm attempting to flash my x900h via fastboot. Getvar all says the bootloader is unlocked. Don't know how but it is. I want to try to downgrade it from android 10 to 9. Don't know it's a good idea. I've extracted flash images from payload.bin. I've attached the photo of what I've got. I don't know exact flash order. Maybe someone can help me with flash order and commands?

Getvar all freezes my tv. However some other getvars do work. Btw: I have to hard reboot (unplug) the tv to get out of fastboot.
Where did you get payload.bin!?
I would love to be able to have bins from a Sony firmware package encrypted) PKG, or from my current setup! (see my BIG post, point 2.2)
Keep us posted if you success, and if you find a root way.

Is there any way to get to fastboot mode without booting from system with adb? Maybe some power cord and button combo? I have only 1 button on my xh90.

Yes you can. I remember someone doing it by either holding one or more buttons on the back of the TV (maybe Power and +) and then plugging the tv back into power, OR holding keys on the remote while plugging tv back into power.
'Normal' phone Androids always want either Volume + and/or - being held while powering on.

WARNING: Power and - means a factory reset says Sony.

However, why wouldnt you do it with 'adb reboot bootloader' with a USB connection or over the air (with adb connect)?!

My tv has only power button. I wanted to boot to bootloader cause it was bricked. I've flashed it with fastboot to downgrade. But then it was stuck on "updating" screen. Maybe if I could boot to bootloader I could fix it. Anyways sony fixed it for me ;)

Hi DNA,

Are you the same 65" Sony TV? My model is also showed Bravia VH2.

Do you know how to root?

I tried Kingo Root, but it doesn't work.

Hi,

Does anyone know whether Sony ever would upgrade to Android 8 on KD-65XD8505? Mine is produced in April 2016. If I am not mistaken (reading from Sony support page), it received last fw update v5.457 in April 2021, which if I get it correctly brought along Android 7.

Talked to local Sony dealer here who was doubtful, believing that newer android simply would not fit in memory. Newer android would be helpful as my tv service provider offers an app which supports Android 8 or higher....

As I already stated/asked in my 'big post' on page 85 ('part 1'), me too am really wanting to finally get this update, as DID the rest of the world! So strange 3/4 of the world with this exact tv already received it.
I get more and more Android apps that stop supporting ATV 7.0 :(

I mailed Sony about it 2 months ago, and they answered:

"With reference to your enquiry regarding your Sony KD-55X8505C, we are sorry to learn about your frustration that Android 8 is not available for your TV yet.
We would like to explain that, unfortunately, we do not have communication regarding whether or not or when the update will be available in Europe. However, we recommend bookmarking the following page and checking it regularly for updates on this matter:

Thanks, it kind of sounds like it may come. Also, if the rest of the world has it, could a manual flashing work or it would brick the TV?

Sony Bravia 4K 2015 (KD-55X8505C EU)

(Types/model explained: KD=TV,55=inch,X=premium,8=model,5=submodel,05=localdesign,C=2015)

WARNING: Everything is AT YOUR OWN RISK (as you may brick / destroy a good TV)!

Hi guys/gals,
I am still using this Android TV 7.0 by Sony (Bravia), and have lots of info, but even more questions still, most important being:
Part 1) Can I install the newest international (US/Asia) firmware (6.827 - Android 8.0) instead of our much older lame EU one (5.457 - Android 7.0)? Same hardware thus compatible or??
Part 2) Can we (temp) root it, and/or unlock bootloader, and/or install Magisk or any other custom images? Can I downgrade / revert back to older firmwares (to make it weaker to root)?

A lot of info can be found via the links (like the BeoBuild Vision & SmartTVHacking) and in the attached files from my TV.
ADB can be connected remotely, by first enabling Developer Options & USB Debugging, and using the IP of your TV in the command: adb connect [IP]


Part 1
I am still running 5.435 because it may be weaker. It would also may be able to downgrade, to re-enable some holes/weaknesses (see 2).
I would love to upgrade to Oreo (8.0) like everyone in the world with this TV except Europe.
Is it possible by;
1.1) Altering the firmware of Sony (see 2.2) or the download method by changing the IP by local DNS etc.?
1.2) Changing the TV region/settings/specs so it fits (see Service Menu)? Is the hardware exactly the same as Asia or US or is this dangerous?!

Part 2
2.1
) Can we unlock the bootloader? I can boot to fastboot, but did not dare to try. There is no OEM Unlock option in Developers Options in Android.
Btw: A 'getvar all' in fastboot will give the partitions and then crash. A hard reboot is needed and then a 'fastboot reboot'.
2.2) Can we extract (or even package) the firmware (PKG = EPK?) files given to us by Sony? Binwalker seems to give us some but it seems you need a specific (unknown?) key to extract all, or to (re)package. For some other device types there are hacktools to extract firmwares by Sony, epk2extract by OpenLGtv or the older fork, pk2extract by p0isk (for same chipsetted HiSense, LG, Philips etc.)!
2.3) Is any of the hardware vulnerable? Like the MediaTek MT5890 (= MT5595 = ATV1) or Bluetooth chip/stack (using BlueBorne etc.)?
2.4) Can we use the serial method (RS-232C) using the mini jack (or VGA port) to connect and do some stuff?
2.5) Is Google (Chrome)Cast (this old 1.56.275391) vulnerable, or usable to do malicious stuff? Ports 8008, 8009, 8443 and 9000 are open. Maybe with altered sploits like HubCap or FlashCast etc (Team Eureka & fail0verflow & GTVHacker)? We can influence it anyways by using tools like pychromecast etc.
2.6) Are Sony's own systems for streaming and remote connection vulnerable? See Links for Control by Serial/IP/HTML5.
2.7) Are any of the preinstalled apps vulnerable, like Vewd browser (see links!) or any lib (see links!) etc.?
2.8) Does any of the closed source one click rooters (KingRoot/KingoRoot/One Click Root/Root Genius etc. etc.) work?
I will never try and do not trust rooters! It was mentioned that King or Kingo works by some users (own risk!).
2.9a) Is the so called TVoodoo attack by Valerio Mulas (using a Rubber Ducky / Remote IR spoofer) a valid one, or just a fun idea to use ADB etc?
2.9b) Can we use hidden/secret/extra IR codes (non official) to do stuff? In other words, which keys of the IR matrix are mapped or on any official remotes, and which ones are ALSO received/interpreted/useful?
2.10) Was the port 12345 (now closed) attack Nimue possible on our TV with older firmwares (seems only up to 2012)? And universals like Framaroot? Towelroot? BlueBorne? Etc?
2.11) Is the p0isk kernel to any use for us/me?
2.12) Can we use exploits like within Metasploit? Any vulns/exploits for Android in general? Like the mp4 HEVC-fright PoC (CVE-2019-2107) or Janus PoC (CVE-2017-13156)(with ie unsigned AmazonVideo.apk) or any User-After-Free (UAF)? Must be, with such old hardware and software a few years old!?
2.13) Injection/escalation possible using the Sony Channel Editor software or 3rd party ChanSort or SDBeditor etc? I remember another (Sony?) to be vulnerable to injection of chars/code into the channel list (sdb.xml) or so when (re-)importing to the TV (in Android or in Service Menu!)?


Service / Secret / Diagnostics Menu
Diagnostics menu: TV is off, then press in this order: i+ (or DISPLAY) > 5 > Volume DOWN > Power (on)
Service menu: TV is off, then press in this order: i+ (or DISPLAY) > 5 > Volume UP > Power (on)
Use numbers 1 and 4 to select item to adjust, and numbers 3 and 6 to adjust item (8 + 0/Enter will restore factory defaults). Then use Mute + 0/Enter to save (word Write will appear). Then turn TV off.

A Chinese developer had posted a exp which could root Bravia with Android 8. (https://github.com/LIznzn/CVE-2019-2215) it did't work for my x9000h with Android 10. But I hope that's helpful for you.

Very nice! I already stated (2.12) that UAF (CVE 2019-2215) could be the way.
This specific UAF by Llznzn may be our holy grail. The bug was fixed 2019-10 and my tv is still on the older firmware (2019-05) and not newest.
I will post any results asap. I am not a programmer, but it may be needed to find other specific offset. Hope someone could help if needed.

Thanks for spotting!

So I just ordered a 50x90j that is going to be here today.

I have a few question before it arrives:

  1. Does anybody think they'll add the PiP feature like all other Android TVs have?
  2. Is it possible to remove the ads from the home screen?
  3. What is the best sideload launcher?
Coming from an LG 40j7700.

1. Why would that be not possible? Lots of Bravia can do it as you can find everywhere on YouTube and Google? And on specs pages like this one.
Btw: On many televisions like Samsung and Sony, there is a secret service mode, in which you can enable PiP/PoP. See my 'big post' section Service Menu.

2. You may root the tv, and then use AdAway or DNS services with ad-DNS blocking like this or this. Or put those DNS services in your home router/modem to block them all in your home network.
Second thing is to remove all the bloatware by (wireless) adb by hand or with any of the scripts like this and this. And dont forget to disable the Sony Shelf etc. And keep HOME button long pressed on any app shortcut to replace/remove it.

    Thx in advance.

    Tried to debloat but command prompt said my device refused (or denied) connection... so no usb debugging prompt on tv.

    Enviado desde mi SM-G950F mediante Tapatalk

    First you need to enable ADB on your TV and allow your PC to connect (YOUTUBE HOW TO).
    Second you need to connect to your TV via your PC by using adb. (Minimal ADB package)
    Then use adb connect IP_OF_YOUR_TV and verify with adb devices (should list 1 device) (Search google "adb how to connect to device")

    So if you want to remove a package from your tv, you put both commands into the text file, like this.

    adb shell pm uninstall -k --user 0 HERE_COMES_THE_PACKAGE_NAME
    adb uninstall HERE_COMES_THE_PACKAGE_NAME

    You can put all the commands of packages you want to remove into a text editor and save it as a windows batch script (google it). Then put it into the directiy with adb.exe and run it after you connected adb to your device. That way it will remove all the packages you listed in the file one by one.

    If a package doesn't exisit on your TV, it won't hurt anything. Also all packages will be restored on factory reset of your tv.

    List of packages that you might want to remove for better performance of your TV.

    I've had my XBR55X850C for about a week now and thought I'd share some tips/info.

    Updating the TV

    First thing you should do is update your TV. There were 2 types of updates available for me and I believe I did these in the wrong order and this caused my Netflix app to disappear (instructions to fix this down below). There was a Sony update and there was an Android update. I installed the Android update first, then the Sony update (which took forever). I think I should have done this in the opposite order and would have probably only needed the Sony update. To install the Sony update, you will see an app with a green icon called "Sony Select". Choose this and you should be prompted with a message saying that an update is required. Follow these steps to update your TV (takes about an hour). Once this is done, check in Settings to see if there is also an Android update available and install that as well. Once that is done, below are some tips I'm providing based on my user experience to get the most out of your TV.

    Playing Video Files Over Your Local Network

    I'm a cord-cutter and as such I watch files off my network frequently. I don't prefer using DNLA servers like Plex because there's really no need to have everything transcoded from your media server to your Android TV device since my Android TV has enough processing power to handle playing my video files over my network. The simple solution here was to go to the Play Store using my browser from my computer and install ES File Explorer and MX Player Pro to my Sony Bravia. Now I can browse my local network with ES File Explorer, find the video I want to watch and open the video with MX Player Pro.

    MX Player [Pro]

    Regarding MX Player, one big tip I can give you is to make sure you have the codecs installed for proper audio output. Got mine here: http://forum.xda-developers.com/apps/mx-player/mx-player-custom-codec-dts-support-t2156254

    Another helpful MX Player Pro tip is to use HW+ for video and SW for audio. Using HW+ for audio causes laggy, out-of-sync audio and anything other than HW+ for video causes stuttering, at least with this TV it does. Fortunately in MX Player settings, you can set HW+ default for video and SW default for audio. So far this combination works flawlessly for MKV, MP4, AVI, etc.

    Installing APKs

    Once you have ES File Explorer installed, you can also browse a network share and install APKs directly from the network share. Works great!

    Fixing Missing Netflix App After Update

    If after updating everything, you lose your Netflix app like I did, the solution was simple, but requires ES File Explorer to be installed. Using ES File Explorer, I navigated to /system/app/ and launched the netflix-ninja-release.apk file to reinstall Netflix.

    Restarting Android / ADB

    Occasionally I felt the need to restart Android to resolve some issues I encountered from messing around with things. However, the only "official" way to do this is to unplug my TV which seems a bit archaic. Currently, without root, the only other way I've found was to enable developer options and use ADB wirelessly to reboot Android. To do this, just like on your Android phone, tap on the build number repeatedly until it says developer options unlocked. Then I had to restart my TV by unplugging for 10 seconds and plugging back in to get the Developer Options to show up in Settings. In there I enabled the ADB features.

    Next you connect to your TV using ADB wirelessly by issuing the following command: adb connect {ip of your tv}

    Then you can restart the TV by issuing: adb reboot

    You can ADB into your TV using a terminal app from your Android phone as well, so a computer is not necessary.

    EDIT: Just discovered that I can restart Android on my TV by pressing and holding the power button on the remote control for about 10 seconds. Don't need ADB any more.

    Control PS4 (or PS3 Slim) with Your TV Remote

    Lastly, you can set up Bravia Sync with your PS4 (and/or PS3 Slim, PS3 Phat doesn't have HDMI-CEC) to control the UI of your console using your TV remote. This is very nice for Blu-Ray playback. Just hook up your console to an HDMI port and turn it on. Next, on your TV go to Settings -> External Inputs -> Bravia Sync Settings. Turn on Bravia Sync Control. Next, go to "Bravia Sync device list". You should see your devices listed. Press the "Enable" button. That's it. Now when you select the input for your PS4 (and/or PS3 Slim), it will automatically turn your console on and the console can be controlled using your TV remote. It also works the other way around. You can press the Playstation button on your controller and this will turn the TV on and automatically switch it to the correct input for the console.

    Just thought I'd share some helpful tips and save someone else some time in getting the most out of this awesome TV. Hope this helps others out there.

    I pulled the build.prop from my XBR55X850C. See attatched.

    Some tips besides what I've already posted before.

    Get Rid of the "Featured Apps" Section
    1. Go to Settings -> Apps
    2. Look for an app called "Sony Shelf"
    3. Force Close it
    4. Set Notifications to "Off"

    Get Rid of the "Sony Select" App and its Recommendations
    • Go to Settings -> Apps
    • Look for an app called "Sony Select"
    • Force Close it
    • Set Notifications to "Off"

    This will take effect immediately upon returning to the home screen/launcher. This gets rid of (or hides) that unnecessary row of Featured Apps or at least prevents it from showing up on the home screen/launcher. Many of these apps listed in this row weren't even installed on my TV and when I launched some of them, I would just see a blank screen. This also prevents anything from showing up from the Sony Select app. Like the Featured Apps row, this app is useless as it showed many services that I never used or that didn't even work or it just showed apps that I can simply launch from the launcher. Now your home screen/launcher looks just like stock Android TV as Google meant it to be (bloat removed/hidden).

    OK, you need to explain this. :) Did you swap boards in your device, or swap SOCs, or ?

    What root process, and do you have pics that illustrate root working on the TV?

    Very cool.

    As you can see, this tv has no panel (screen) at all.
    Its just the boards that's needed to be able to work.
    The psu is not original. Its just a generic laptop 19v 90w charger.
    The tv boots up, I can connect to it whit adb and hacking. ;)
    Full nand dump and steps to achieve root to be released. :cool:

    Solution non-starting KDL-W756C

    OK, my box had simply failed to initialise past a white screen with a blue wave asking for langaage select. Sony Support just wasn't!

    Software updates only load on the machine if they are later dated than the one installed. I'm in the UK and found a later one on the Dutch Sony site and loaded that from USB. but it FAILED to coorrect my problem. The machine got stuck initializing. I suspected a bad cache or corrupt userdata. Previously I'd noticed some apps refused to start.

    So here's what you need.
    Even before you thought your box might fail you should have gone to Settings - About and clicked on Build seven times to become a developer. Now find the new Developer menu in Settings and choose Debugging. Set ADB debugging on. This is important. It will give access to your box if it needs a proper clearout.
    with that done, follow the rest if and when you need to...
    Code:
    adb connect "IP of your box"
    in my case on my network 'adb connect 192.168.1.19'
    then
    Code:
    adb reboot bootloader
    the machine restarts. Adb doesn't release, so in the console window type 'ctrl C'.
    Now connect a USB DATA cable - male each end (full four wires; its important) from your laptop to the TV.

    EDIT: The cable I used was from old equipment and appears, after testing to be Data+ to Data+ , and Data- to Data- i.e NOT a normal USB Data cable.


    Now enter...
    Code:
    fastboot devices
    and you should see a set of numbers and fastboot ... somthing like this...
    "8000ac9b8a0bbc9f fastboot" confirming that you are connected OK.

    Now from the console enter
    Code:
    fastboot -w
    the machine response is something like this:-
    erasing 'userdata'...
    OKAY [ 0.043s]
    formatting 'userdata' partition...
    Erase successful, but not automatically formatting.
    File system type not supported.
    OKAY [ 0.732s]
    erasing 'cache'...
    OKAY [ 0.041s]
    formatting 'cache' partition...
    Erase successful, but not automatically formatting.
    File system type not supported.
    OKAY [ 0.732s]
    finished. total time: 1.548s

    Now here you might be quite worried (I was!!) as the cache and userdata hasn't been formated but continue..
    Code:
    fastboot reboot

    Don't worry the machine seems to take forever. The Sony logo comes up. The machine reboots the sony logo appears again. Eventually you'll see the boot process with the coloured balls and all. Proceed as for a new install.

    Why couldn't Sony tell me that?
