I have seen several threads with issues similar to mine; however, none with this exact issue. Everyone seems to be running into trouble trying to install updates or flash the unit. This is not what happened in my case. I bought this Android Head Unit on Ebay a few months ago. It has been working just fine until a few days ago. It gave me an error message about "tw has stopped" or something similar. All I could do was press "ok" over and over again. It just kept popping back up. So, I left it alone, got where I was going and turned the car off. When I turned the car back on all the unit would do was either show a white screen, a screen with multi colored lines, or the boot up logo (Toyota symbol in my case) and then back to the white or multi-colored screen. It has gone to the "Android" logo a couple of times; however, never gets past that point. I hear static. That's it. I put a CD in and it ate it. Won't give it back. I've pressed the reset button. It just loops back to the blank screen with static. Sometimes it will boot all the way to the Android logo but no further. Most of the time the backup camera is not working. If the bootup gets to the Android screen, the backup camera will work. I emailed the Ebay seller and they said they were going to send me a file. When I asked when they were going to send me a file they said "Hello Friend, the Android 6.0 update is not ready yet". I emailed again and asked if they could just send me a file to restore the current version. I'm kinda stuck until they send me a file I guess. I don't really know exactly what version I have on there now. 4.4 I think; however, I know there is a lot more to it than that. I wish I'd made a restore file (if that's even possible). Also, there are no instructions as to how to get it to boot into recovery mode. I've tried lots of combinations of buttons, but I'm really just shooting in the dark here. Any helpful information anyone might have would be appreciated. I really have come to depend on the Navi and other functions. This unit fits right in my car and looks really slick. I was really enjoying having it until it quit working....
Hi, I have a question, how can I do a hard reset to my unit? is an MCU1: HW8227L-3.3-SW0-1.9 WITH ANDROID 8.0, I already tried to do several YouTube tutorials but I could not, it brings two wires of key 1 and 2. try to change the logo and the wallpaper and after turning it off, it is no longer turned on normally because it does not even show the android logo and starts to restart.
PLEASE HELP
Hello everybody,
I bought a Bosion car radio in 4 / 64GB (px6/rk3399/2.0Ghz) version a month ago with dsp, and android 9.0 installed.
After 1 week, after ignition to on, it shows me the welcome picture, and after the android logo loading, and it runs in a loop.
After contacting the seller, he sent me the program to install on SD card with all the steps.
I followed everything step by step, then I insert the sd card and switch on the car ignition.
I briefly see the android logo and the screen goes black (the backlight remains on, the buttons on the side also light up with the headlights)
I don't know if it's a software problem or a hardware problem,
This is my first Android car radio and I'm a little lost,
If any of you can help me I would be grateful,
Thanx in advance
have a look here

Thanx !
I installed everything on the sd card, the update went well.
Only, now the car radio starts up, welcome appears for 5 seconds, a brief black screen appears and it goes back to Welcome on a loop.

Then I think you need to install the firmware at that point, I'm not sure as it's never happened to me

I just installed android head unit Isudar model H53 HO0923 but after 4 days got split on screen.
After asking some advice from maker the they sent me a firmaware to update but screen kept split in two after update.
Few days later the sent me a file for updating (but this time the content was only 1 file (abt 600kb).
After trying to update with this 1 file then the screen become blank but backlight of screen is on and all buttons on the side of screen are alson no function.
I asked again for advice but still no answer yet.
I have now clue about this problem anymore.
Note: I tried to install any firmware from Isudar but the screen remains blank.
Is anybody knows how to solve the problem to get the screen back to normal. At least until showing android logo in oder to see the progress when installing firmware, thanks a lot in advance
Hello, I'm new here !
I bought this Android car radio (https://fr.aliexpress.com/item/3280..._list.0.0.72ab5e5bmptYkx&gatewayAdapt=glo2fra) years ago.
But today it goes to black screen without reason and the reset button just restart the unit which goes to black screen - I tried to ask to the vendor but i get no answer..
Could you help me to find the original firmware/rom to perhaps make it work again ?
Thanks for you support
