If someone using latest Marshmellow update of the Joying Intel Sofia 3gr HU could extract launcher as apk, I would be grateful.
Thanks in advance. :)

    Android 5.1 to 6.0, 2gb ram INTEL cpu Rom updates & ROOT links.NEED HELP TO BUILD ROM

    This unit works and sound great..However there are a few thing i would like to be able to power off instead of hibernate and or set hibernation time...I would like to have back up of the shipped original rom... And dual boot os..or roms. Change buttons and switches on tool bar...Does anyone know if there is a way to dump mcu firmware....... All ideas and suggestions welcome and appreciated!! ...
    Looking for help and insight into this head unit..1) lets make this rom better that joying has released there intel unit i would like to get a copy of there rom and compare .... Also ANDROID 6 may be In the near future links
    thanks in advance
    cpu info
    intel link
    rockchip link same cpu
    on the intel link a little ways down the page it says
    The Intel® Atom™ x3-C3230RK processor, a collaboration between Intel and Rockchip*, includes a quad-core 64-bit Intel® Atom™ CPU and an integrated 3G modem. Figure 3 describes this SKU’s high level architecture

    cool link from dongali thanks
    How to extract installed apps as apk guide:

    cool link from doitright thanks
    It looks like we should be able to get some code and kernel for android we just need to find someone to build a roms for us

    food for thought can we do something like this for our intel units ...this could open some doors for us
    wasn't necessary thinking Linux ubuntu only...but if you made bootloader look for a system on a sd card android,linux,windows, could have a dual boot system....this would be awesome it would make it easier to mod system files and experiment with different os and have the ability to pop out the sd card and be back to stock config if you didn't want to boot off sd card make an sd card to redirect boot loader back to internal system...or if bootloader can't find a os on sd make it default back to internal system. ..I think something like this would be one of the best things that could help speed up development and allow roms that were built for different partition sizes and systems become more Universal .
    Anyone want to chime in
    Can this be done

    where unit was bought

    firmware update link 10/12/16

    original firmware update version link
    the root link is a few pages back in this thread i think around page 23 .. on a fresh formatted usb copy ..flash from usb1 . dont check wipe
    root link

    Joying firmware link

    this can be the answer if can this be done with our head unit.....
    This app only works on selected devices. Check the list at the bottom of this description.
    This application requires root and it is designed to be used by experienced "power users".
    It is strongly recommended to read XDA thread before installing this app, you can find links at the bottom of this description.

    MultiROM Manager can install or update MultiROM, it's recovery and kernels. It can also install Ubuntu Touch system-image based builds into MultiROM as a secondary ROM.

    MultiROM is one-of-a-kind multi-boot mod for Android devices. It can boot any Android ROM as well as other systems like Ubuntu Touch. Besides booting from device's internal memory, MultiROM can boot from USB drive connected to the device via OTG cable. The main part of MultiROM is a boot manager, which appears every time your device starts and lets you choose ROM to boot. You can see how it looks on the left image below and in gallery. ROMs are installed and managed via modified TWRP recovery. You can use standard ZIP files to install secondary Android ROMs, daily prebuilt image files to install Ubuntu Touch and MultiROM even has its own installer system, which can be used to ship other Linux-based systems.

    .Here's the deal... if we could dual boot another android os for head unit let just say rom from joying or other brand/manufacturer you could test rom see what works and what doesnt , modify rom ,extract apps from rom and if rom was better you could make rom you primary boot ..(i also believe we could add or mod the mcu part back in the rom).... and you would be able to test this all with out erasing you stock configuration or stock rom would be able to test and develop new updates as they come out.. you could test with out erasing or wiping your system.. you could run Ubuntu ,Ubuntu touch or other more pc based os and still have the ability to reboot and be back in radio os android mode....and I think there is a fun factor here with experimenting and adding more function to the head unit
    This is what XDA is all about right WHO 'S WITH ME:
    Well, this seller also tells his unit can't be upgrade to 6.0....

    "hello friend
    this can not update android 6.0
    we willl recommend 6.0 os in the end of this month
    you can take care of our store
    thanks alot "

    Do, PLEASE, keep in mind, that you are talking across a very steep LANGUAGE BARRIER.
    When you ask them if the unit can be upgraded to "android 6.0", they aren't answering the technical question of whether or not Android 6 *could* run on the unit. They aren't even answering whether there are or are not plans to CREATE an Android 6.0 upgrade for it. They are ONLY answering that there is NOT CURRENTLY ANY UPDATE FILE AVAILABLE FOR IT.

    I *absolutely promise* that these units ARE capable of running Android 7.1 or newer.
    And given that these are now INTEL cpus, a lot of the undocumented rockchip crap gets to fall away, which means that **WE** might be able to generate such an update without the manufacturers providing anything.

    Can anybody confirm that new units (Intel 2 GB RAM) have sdcard slot?
    Hotaudio people that new unit has no sdcard anymore. The slot is for.a 3g Sim

    This is pretty hilarious...

    More about the LANGUAGE BARRIER.....
    The Intel units DO INDEED have an SDCARD slot.

    I'll tell you where this silly idea of no-sdcard slot came from;

    Meet the JY-UL128 product page;

    It says at the very end of the "quick overview" section, "No SD card".
    Let me repeat that again so it sinks in: "No SD card".

    Lets consider those words very carefully, and try to understand what that means from a LANGUAGE point of view.
    What it does NOT say: "No SD card SLOT".
    It literally says "No SD card".
    It does not ship with a CARD IN THE SLOT.
    The slot, as it ships, is EMPTY.
    But it is there. The slot, that is.

    Look here, this is the product page for the JY-UL128N <-- N for "iNtel". Note: the one that everybody wants is the "N2" for Intel/2GB.
    If you scroll all the way down to the specifications section, it is pretty clear that "Support micro SD/SDHC (1-32GB)" and "Maps: Built in head unit or Memory card".

    So yes, it does indeed have an SD card slot.

    Oh, and the slot is labeled as "GPS". That really does suggest that that is where your maps go.
    Just for comparison sake, at 24000 that's somewhere around where a Galaxy S4 is, give or take a bit. The Rk3188 should be somewhere in the 13000 - 17000 range.
    The kernel can lie about the CPU to ANY software.
    But there is ONE trick that you can use to actually test it out -- build an application with NDK/native component ONLY for x86 CPU architecture. If it runs, then its x86. If it doesn't, its ARM.

    Makes no difference what you think you see, it is what it is, and it is DEFINITELY a liar.

    ---------- Post added at 07:52 PM ---------- Previous post was at 07:51 PM ----------

    I've already indicated all that is necessary to PROVE THAT IT IS A LIAR.

    Or not.

    Why start with view point that it is fake it has not been proven so and I dont see how your argument establishes fact.

    I too have outlined that there is a hardware difference and that the wifi/bt has moved onto the SOC (which is part of intel SoFIA as is 3g) or are you saying that too is fake?

    Also, no one here is being disrespectful to you, so please do the same.

    Hey, wondering if you could extract the stock Vehicle Information app into a backup .apk file to share with MTCD rk3188 users to test cross compatibility.
