Hi everyone
I have a chinese car stereo with dvd brand ar 6002b
android 6.0.1
mcu: 2017.10.23: 09: 49: 07 fY_ (NOR) _90_C9_7706_6023_NEWLAP_ 18E
PROCESSOR
CPUintel atom 4quadcore gpu4d mali-450 MP4 ROCKCHIP
i tried to change firmware trying with joyng ones, i tried your custom gtx
but i have problems with
audio. the volume does not work, the radio does not work and a green bar remains at the top with Chinese writings and it does not go away even when modifying the prop file.
after several searches I found a perfect firmware where everything works even updated to android 8.0.1
but it has a different bigger resolution, my car stereo is 800x480 and the firmware should be 1024x600
the question is: is there a possibility to change the resolution to 800x400?
thanks in advance for any help
sorry I don't speak English, I made do with google translator, I hope you understand

I don't want to sound insistent but the only thing I ask you is to know if I have to resign myself or someone from this forum can provide me with a link (if any) for the firmware of this car radio that I have described in the posts above thanks
is there someone so kind who can recommend me a firmware to install on the car radio in question I would be really gratefu,l any version of android is fine, as long as it works now the car radio is out of order because I can't find a firmware that works
thank you very much for your answer I try the firmware and let you know
I can't install the firmware, I insert the USB key the installation starts and after a while it stops with error: verification signature failed, I have this error with any firmware you try to install this error appears to me since I installed the latest firmware from recovery the firmware was new sofia4, i can't enter the recovery i can't install a recovery through adb because the pc doesn't recognize the car radio. before installing new sofia4 all the firmware installed perfectly i would be really grateful if someone told me how to avoid this error and finish installation thanks

Hello. I wanted to upload android 8 using modinstaler pro from hal9k. I did everything as in the youtube movie. I installed modinstaler pro on the radio and installed the update file on usb.
I turned on modinstaler pro and pressed android 8. After pressing Ok, the radio turned itself off and does not turn on.
I don't know what to do now or how to turn on the radio. am radio android 6 mtce px5.
With very little detail as to what has been tried to recover, suggest the following. Always provide detail to help others help you, there is inly frustration in guessing games.
Try recovery steps listed in that thread, if unable to recover use OTG method listed in my signature.

it has the dvd should be sofia 3gr because it has the 4g slot for the sim card
the car radio brand is ar6002b this:
https://it.aliexpress.com/i/32844402782.html
I tried many firmware and it made me install them all without errors only that either the speakers did not work or the volume did not work properly, I have the latest firmware that I could install is this:
https://docviewer.yandex.ru/view/0/?*=NRuIb5k%2Buqs71e5VUE2pQQGTRKJ7InVybCI6InlhLWRpc2stcHVibGljOi8vQ1dueWZoYjBBbzRuNnVrczVaYU9CNWpFK3J6a2IyTTRIcHViUSs3ejZxVT06L0ludGVsIFNvZmlhM2cvTmV3NF9zb2ZpYV82LjBfM2coMjAxNzA0MjQpLjd6IiwidGl0bGUiOiJOZXc0X3NvZmlhXzYuMF8zZygyMDE3MDQyNCkuN3oiLCJub2lmcmFtZSI6ZmFsc2UsInVpZCI6IjAiLCJ0cyI6MTU5ODQzOTgyMzU1MywieXUiOiIxMTk1OTk4ODUxNTk3ODc4MDQ5In0%3D
I installed this firmware from recovery, after installing this firmware any firmware (which previously installed me correctly) now I insert the usb key part of the installation and it gives me an error (verification signature failed, last flaged sofia6.0, fixed sofia to wifi, start parse board config after)
I don't have the possibility to enter recovery because it gives me an error:
supported api: 3
last flagged sofia 6.0
error whait here.
I do not have the possibility to connect it to the pc because it does not recognize it I have tried several drivers, if anyone can help me I would be really grateful
thank you
after 10 days of testing yesterday I finally managed to restore the situation.
I briefly explain what I did:
before installing the firmware that had caused the problem I had installed a recovery that is used to install
the custom rom gtx 9 but even if I tried to enter it I could not
then without any hope I copied the firmware gtx v9 on a usb stick
I did the procedure from the keyboard to enter recovery (alt- stamp list- e)
the car radio restarted and the recovery magically appeared and did everything by itself without me touching anything.
now i can install any firmware without errors
I have only one problem left that I am trying to solve, the DVD does not recognize me I do not know if it is enough to install an apk to make it recognize
there is someone who knows how to recognize the car radio dvd, a green writing appears at the top with dvd and other words in Chinese equal to that, now I have installed the gtx v9
but i have the dvd problem
thanks for any reply

Hi I have similar device but my device is not detected by my computer. How can I take so flash tool backup
Hi I have made a video tutorial on how to make stock ROM backup
Hi friends,
Have you are observed overheating of touch panel of your car stereo or hangs in your Android car stereo or system not responding or application keep crashing etc.
Then this video is for you. I have done this small modification in my car.
I made a small hole on sides of AC vents such that cool air blows over the heat sink of Android car stereo and two cpu fans of 12V take power supply from same connector.
Whenever the car stereo is turned ON the fans also turn ON and blow cool air over the heat sink to keep it cool.
Hi I have made a updated video tutorial with added info on how to make stock ROM backup.

Hello,
i have a "Bosion" px6 android 10 (really 9) headunit which was from aliexpress.
i had an issue with the "autokit" carplay app showing artifacts, and the solution from the seller was to downgrade.
i was originally on
OS VER: KC1E0129-P01-11.1.4.9.1 - BLINK161 - 20210118
MCU VER: STM32-20210109-11-BD6-56
The seller provided me with
os_update_KC1E0124-PA1-1.1.4.8.1_20200729_180609
mcu-202007071001KC6-1154.upd
The update steps provided by them was as follows:
First update OS then MCU
i updated (or downgraded) to the os update successfully, but was missing lots of apps, DSP, BT phone etc, i then installed the MCU update, around 10% in the unit went black and has been in that state since. i allowed 1 hour before switching ignition off and back on but headunit still black screen no response or lights.
Not sure what went wrong? Was the file they provided incorrect?
What can i do in this situation?
Ive attached an image of the headunit.
Ive tried all sorts of recovery options ive read on here and on YouTube with no luck so far - Hopefully someone else can help me.
Thank you very much
Bump
