I had this unit for some 2, 3 weeks now, and while it worked great initially, all of a sudden the radio app started acting up.
It starts with some garbage displayed (e.g. 'jV!fxcj') instead of radio station name, and it is not responsive at all. If I manage to get to home screen or to anywhere else, it will just pop back up to the front, and it keeps happening constantly, Sometimes, after doing who knows what, I manage to kill it, and I can use the rest of the head unit, but that happens rarely. I also tried going to the settings -> apps, and killing the app from there, but it doesn't help.
I hard reset the unit, and the radio worked fine for about five minutes, and then it started happening again. Is there a way to at least disable the Radio app somehow, so the unit is usable in some capacity?
I have exactly the same issue on my TR771L. I got an MCU update link to load onto an SD card but haven't been able to get it to install on the unit.
The looping is really annoying especially at night.
EDIT:
Android version 8.1.0
MCU version T8.3.19-36-10-E53201-180726
System version V9.3.1_2018082.102205_MLT5
I had that problem too and did an firmware update and it seems to be ok now
This might be a stupid question, but where do you get the firmware update from? Is there a custom ROM to be installed on it as well?
I was always confused by many similar but different headunits, and was never sure if something would work on mine or not. Is it PX5? Is it MTCE? Is it none of these? Sigh.
On a positive note, it seems to work better now. I uninstalled the automate car dashboard and know it happens rarely if ever, and even when it does, a hard reset with a pen solves it.
Well, I contacted xtrons with a request for the update file, and they provided a link - https://1drv.ms/u/s!AjrY0uqbW_kBk36dRnJD4d_aaej8
This is a system update file, and after I went through the versions I have are:
Android version 8.1.0
MCU version T8.3.19-36-10-E53201-180502
System version V9.3.1_20181012.103419_MLT5

You need to extract the files from the RAR file, put them on the SD card or USB, connect it to the head unit, go to Settings -> Car settings and then scroll down and choose MCU update or System update. Depending on the file you got, it should detect the update files and ask you if you want to reset the sd card/usb (I choose no just to be safe) and it took a bit of time to update, and the start loading animation (xtrons) took a bit more time than usual, so don't worry about it.
I bought one of these Chinese Android boxes that integrate with your existing head unit and I'm trying to find any information about it, and which forum I should be posting questions to. FWIW I have a VW Touareg with an RNS850 system that is basically the same thing as the Audi MMI 3g+ system, but with a touch screen.
Here is some model and version info:
Model: ZQ8002
MCU: TUREG-ZQAND-1.1
APP: MTK-8002_C37_GA1_DZSJ_DaZhong_EN_2019-05-27
Android: 6.0
CPU: 4 core 32-bit CPU Coetex-A7 @1.3G
RAM: 2GB
Flash: 16GB
Baseband Version: MOLY.WR8.W1449.MD.WG.MP.V61.P3
Kernel: 3.18.19 [email protected] #2
Hostname: fise8321_tb_m (seen via ADB shell)
It has a "Factory Settings" menu similar to other Android head units I've seen mentioned here. That presents a numeric keypad. I figured out a few codes for it:
0000: Bunch of debugging toggles, also toggle for ZLink CarPlay
5555: Just says "ok" when you enter it. I think this turns on ADB over TCP. I was able to ADB to it after this, but I had also use a terminal emulator to enable it.
9999: Single item to allow installation of "APP", which I assume is the firmware?
The box on Amazon: https://www.amazon.com/gp/product/B07PJGLD41/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
Main issues I'm trying to solve right now is that my skip track buttons on my steering wheel aren't doing anything, even though I can see the CAN bus events in the logs when I press the buttons. I'm hoping there's a Factory Setting code I haven't found that might let me change the CAN Bus settings. It has carCanBus and FactorySettings apks that I was able to decompile, but didn't find anything useful.

Hi Albe, is this something I could copy off of the unit? I have not had mine installed for a couple of years, but I am interested in trying to get this thing updated to possibly fix some of the issues I had with it. It may be a long time before I work on it, but if you could provide the file system path to copy the MCU file, I will provide it for you. If it's more involved than just copying a file, just let me know what I need to do or link me to a guide. Thanks!

I don't know how is it possible to exctract the MCU file (.bin) by the interface. I could try to find online anything to do it. i try to find softwars and so on, if i'will try i tell you something. I send many mails to producer of the unit, but everytime i do it, he tell me to waiting for response of the engineering department......and i wait. My MCU was TUREG-ZQAND-1.3 but i think your version 1.1 coluld going rigt for mine.
Not (android-auto) requested moderator move to Android head units forum.

Hi Mondo. I've find how could you extract the MCU file from your ZQ android interface. read the thread that i link you now! I wiat for your reply. https://www.androidiani.com/forum/autoradio-android/546699-f-q-px5-autoradio-android.html. At the end of Point "2" you can read how to export your mcu file! Thanks a lot and best regards.
I received an Erisin ES6292B 9" PX6 for Mercedes Benz.
I don't know why but for some reason I was sure it was a MTCD/E version so without prior checking, I immediately went for the upgrade to Hal9K MOD.
The upgrade finished and the unit rebooted. I am not sure if I saw the boot logo (I think not) but as if this was not enough, during first boot, someone in the workshop cut the power to the car and the unit was bricked!
I wrote to Erisin and they sent me the Stock image to try to apply from recovery. However it is impossible to enter recovery with any way I tried. As long as I hold the reset button the unit is dead. When I release it the backlit starts but the screen remains black even after 10 minutes. No recovery, not even boot logo! It seems the MCU firmware is corrupted.
At the moment I have an ST-LINK/V2 programmer in my hands to go for unbricking with Wadzio method but STILL NO ANSWER FROM ERISIN IF MY UNIT IS MTCD/E or different.
Anyone knows?
Also, anyone knows a direct link to download recovery.bin for my unit?
What are the names of the files that were being applied for upgrade? Are you able to share these - assume you had two files, one MCU and the other android.
Also the stock image ersin supplied.
Note the wadzio Unbrick is for MCU unbricking, are you sure that the MCU is bricked? I.e. you are sure you were upgrading the MCU, because from your description, sounds like you were upgrading the SOM/Android.
Details are everything.

This is the link to the Hal9k PX6 Custom ROM
This is the link to my unit's stock ROM
I assume my MCU is bricked because I cannot enter recovery
When there is no boot logo, I guess it is the MCU. Correct?

The zip doesn't contain an MCU, and is an android OTA zip, therefore if your power outage occurred while applying this file, the SOM emmc/nand is probably corrupt, and you might not be able to enter recovery.
I've had a number of SOMs sent to me exhibiting the same symptom, so not uncommon.
If unable to SDCard boot, SOM recovery via OTG is the likely path to recovery. Refer my threads/signature.

I still have not managed to find out if my MCU version is MTCD/E or other. Still waiting for Erisin's response. They requested a video with symptoms which I already sent.
Supposedly my MCU's version is an STM32 and I tried to install Hal9k's ROM (specific for MTCD/E) wouldn't that corrupt the MCU? To my thinking, this is the most probable scenario.

The files you list are not MCU updates.
Its trivial to determine if you have an MTCD MCU using Wadzio's decryption tool, however & once again, the MCU is separate to Android. You cannot flash the "wrong" platform MCU (ie. MTCD vs STM MCU) in recovery.
Once again; the files you list are ANDROID and not MCU. Unless you havent described what you were doing to "upgrade" the unit, which lead to corruption; the SOM is bricked and not MCU.
Again, for clarity, MCU and ANDROID are not the same. They are separate images and cannot be flashed together.

Kind of getting there. Ha ha, my knowledge is very epidermic! Tomorrow I ll try the SOM recovery via OTG as you suggested and report. Thanks for your time
Just a (silly?) question: Could we say MCU is equivalent to bios on a PC and Android is the equivalent to PC OS? If the MCU (=bios) is still untouched, even with Android (=PC OS) corrupted, why is it impossible to boot from SD or simply access recovery?

Hello. | have an Erisin ES6283C 8" Android 9.0 Car Stereo DAB+ 4G WiFi HDMI GPS Sat Nav for Mercedes C/CLK/CLC Class W203 W209.
They (Erisin) provided me the same stock ROM as yours.
For sure your MCU is STM32, as mine.

The MCU is more like say an auxillary fan and button controller, connected to a serial port, but still controlling the power supply to the computer.
Why impossible to boot or access recovery - corrupt emmc/nand.
Your unit doesnt look like an MTCD/E device.
Unfortunately hardware used in my PX6 implementation is quite different from what shown in SOM recovery over OTG page. I don't have the tools needed to uncover the SOM (75W soldering etc). Judging from the bottom, it seems the SOM is embedded on the mainboard and there may not be any pins accessible. However, rk3399 supports what is called MaskRom mode (a relevant link translated from Chinese) allowing programming of the SOM with the use of a male to male usb cable. But this would be possible only if we access the interior and find that the test points to bridge exist. My last resort if nothing else is possible.
Another issue I am facing is that my firmware is not in update.img format but comes in .zip split in several files. I think I need to repack it in .img format in order to be able to program my unit with existing tools and I don't know how
Just a last (stupid?) question. Accessing the MCU via ST-LINK/V2 programmer is possible. If we new the starting memory address of the SOM firmware or the various parts, would it be possible to flash from there?

It is an STM32 eventually. I managed to unbrick it but the MCU was changed. Both firmware and config. I am stuck with an 800X480 desktop on a 1024X600 display.
Can you export your MCU.cfg file and send it to me please? I think you need to go to settings/about then toggle between Kernel Version and OS Version 6 times in total to enter hidden menu. If a password is asked, try 666666 or 123456. From there you can go down and select export config.
Thanks in advance!

I tried to export config data (is the only export in the menu) and it's only a 1KB file. I think it's the config only for HU startup. I searched all the settings (including the Hidden section) and I have nothing to export the MCU config.

Hi! Dumb question: I own an Erisin ES7802B which came with Android 8.0, where can I check or find if I can update my product? Thanks in advance!
Hello all, i have tryied to update my headunit to android 8 using PhoenixSuit, the upgrade process had gone right, but the headunit locks on the android start screen. And i am struggling with it for some months now.
I am unable to make it be recognized by phoenix suit again, nor make it boot to an USB or Mem card made by phoenixcard.
the only thing i could get was it to start in recovery mode, so it read files like:
51eb6df0-cad7-11e8-bf31-afdca4ac0826
52c7b3fa-cad7-11e8-8188-57adc8d05072.0
52c7b3fa-cad7-11e8-8188-57adc8d05072.1
etc.. the name of the files vary according to the "uboot" file i load on the headunit.
I have tryied lots of files gotten from russian foruns, etc to no sucess, even the original files that i got from the maker fails to start the unit.
If i had to guess the problem that make me unable to restore the original android 7.1 i got from the makers, it would be the partitions number and size, i think phoenixsuit had recreated the partitions in the upgrade process and that recovery mode does not change it... so any android that is not the version 8 (that seens to not work on my unit) does not get even to the start screen.
If someone can give me some tips on how to solve this, i had alread tried anything i could understand from the russian foruns and from here to no sucess
Thanks in advance.
So nobody knows how i can get into a "command prompt" mod where i can remake the system partitions or how i can get the headunit to boot from a phoenixcard created USB?
