I've also lost the radio app as well, doing the same thing. The app that controls the cars original radio works just fine. I can try to get the launcher apk since that still exists.

I'm fairly certain I have the original software. As I backed up u it before mine took a ****. Any luck on that update file? Mine will not go past android at boot. No wifi no adb (that I've accomplished anyways) need some help getting somewhere

LEXXXUS801

Do you have a copy of update file and mcu still? I could really use it.

Hi @LEXXXUS801 , I don't have a MCU backup, but I think I can do a backup, MCU don't usually break on a bootloop.
I have android 7 so the firmware i used is this one modded firmware that comes with root, and without the red alert caused for flashing a different firmware than the stock https://drive.google.com/u/0/uc?id=1...xport=download
To boot on the stock update mode, I just pressed the reset button like for 5 seconds, after that I pressed again for 3 seconds, and after that for another 3 seconds, I dont know what exactly its the process but you have to try if does not boot searching for update firmware.

Just put extracted files on the root of a usb drive (only one of the usb port work for this, you have to test which one)

When I used a firmware update, I still had the bootloop, so if the update don't work for you, you must flash a custom recovery, you need a usb keyboard (a wired one) to navigate in recovery. Here do you have the recovery you need to flash (this will make the headunit automatically boot on the custom recovery, you have to do a wipe/factory reset) , use the version of your head unit, either way the headunit only recognize the version of their respective version, in my case I used the android 7 version (i.e. version V8.2.1_xx), in this link change the origin language to russian:

After the wipe/factory reset you have to reflash the modded firmware in order to have a normal boot, (i.e. you need to boot the HU in the update mode using the reset button to flash the firmware), after the flash the headunit should boot normally, just change your settings on extra settings to match our cars/MCU

In a nutshell:
Update/modded firmware did not fix my bootloop
I flashed a recovery
Did a wipe/factory reset
Flashed again the firmware

Please note , if you do not have a bootloop and do this you will lose your original radio features (AM/FM/AUX/CD Player)

@Dukenukemx If you can provide the launcher would be great as well.

EDIT: I think I found our original firmware, here the links:

https://cloud.mail.ru/public/G5Ud/c6cnqXiGU -- Looks like the firmware + MCU
https://cloud.mail.ru/public/2Z9z/EKVzXMMr7 -- Only Firmware

Tested the first firmware's link, but I got a boot loop, I changed the names to match my firmware from android 7 in order to be flashed, android 6 firmwares names are different from android 7 firmwares names (i.e. bootloader search for specific firmware filenames to flash when booted). I did rollback with the modded firmware again.

Thanks man I been looking for something for a while. I found the recovery thing a while ago but all links are dead. Do you by chance still have recovery files? I can't get into recovery to save my life.

Don't worry bro, here do you have recovery files for android 6 and 7, you can put both extracted files on a usb drive, once you boot on bootloader , it will pick the right one to flash:

Remember after you flash the custom recovery, it will boot only in recovery mode, in this mode you must use a wired usb keyboard (try both usb port, only one will work) to navigate through the menu, first you have to do a wipe cache, and then a wipe data/factory reset.

After that you need to flash the modded firmware (4 files on usb drive root) and boot the headunit in bootloader mode (using the reset button method/emergency mode , it's very finicky that way but eventually will boot searching for an update, try to press the button repeatably , you will know when you boot in this mode because on top of the head unit you will see a green text "update start").

After the firmware complete flashing, the recovery partition will be back to stock, so it will boot normally

Please note, on first boot, the air conditioner app would not work, after second reboot will work OK

So, did the USA specific Canbus resolve the ac control problems?

Hey @hardy272 I got all the apk files in my stereo.Don't know which one you need so I grabbed everything in the apk folder. I do know that com.tw.radio_78cc.apk is for the radio and installing it brought back my radio, the one built into the new stereo, the OEM radio still worked fine other than the station numbers being off. I have to look into a radio signal amplifier to boost the signal so I can totally use that instead of the OEM one.

LEXXXUS801

Not sure if they are the same, but here is my apk back up as well from my unit.
