Hello guys. First of all, I've been searching for weeks for any similar situation with mine but couldn't find anything. I have Unbranded Chinese Android Head Unit running Android 4.2.2. with physical button and a reset pin. I tried tonnes of ways to get to the recovery with any possible method and nothing seems to be working.
can anyone show me how to get into recovery or force hard reset on the unit ?
I have attached a few pictures of the Unit info and the circuit board.
i tried to connect a USB keyboard to my Unit and pressed PrtScr + "E" but my unit did not show factory rest option. you can see what happened in the attached video
i will be thankful for you, if you tell me how to get into recovery mode of make a hard factory rest or install a new ROM.
Thanks in advance .

Hello,
I have flashed my rk3066 7" (model s07) with a bad mcu, and he doesn't want to boot.
When i restarted device, i have a black screen only.... no access recovery (reset button power)
I need help for an issue...
Thank much.
You should still be able to get into recovery and reflash with a good MCU. Is recovery not working either?

I have a joying px5 4gb 32GB system
I tried to do an update for Android 8
And the system got stuck in the boot loop
The system loads the company logo and then reboots itself
How to fix the problem and reinstall the system
As Joying has several kind of units having different kind of hardware it is easily to flash the wrong firmware.
ALWAYS mention which unit you have and which firmware you (tried to) flash.
Your info is "non-info".
Now blindly assuming you have a FYT unit using the latest firmware for the right resolution you can try:
Put a USB-disk with the firmware in the unit. It might be picked up immediately after reboot.
If not: Put a USB-disk with the firmware in the unit and reset the unit with a pointy thing like a needle.
If that does not help: Put a USB-disk with the firmware in the unit and reset the unit. When the boot logo appears, immediately reset the unit. do this 3x until the leds start blinking pink. Then it will go into forced flashing the unit (if a usb-stick is inserted).

I assume you mean JY-UOS03P4
And which file?
You need the top firmware download from this page: https://www.joyingauto.com/blog/
this one if you have indeed a JY-UOS03P4
My system came with Android 6
I tried to upgrade to 8
It seems that the files that are still sitting in the system are of version 6 also where the same steps are performed?
Where can I download the version 6 back to restore the system and then upgrade it?

Its not working on me. I have the same device as ExL360, and the same problem. I tried many ways to enter the recovery, but they do not work. Maybe someone has already solved this problem, or what else can I try?

Hey guys,
I bought a Navigation System M779 (androidautoplayer.com) for Suzuki Grand Vitara from AliExpress one month ago.
At first, everything was fine and I was very happy about it. Nothing to conplain about.
Then I went on Holidays for about 14 days, in which the car wasn't used in any way.
Yesterday I started the car for the first time after Holiday, the battery still was fine but the radio did not boot. The screen stayed black and the Buttons did not light up.
After checking the Plugs on the back, the screen showed a Bootlogo, but got stuck.
I did not modify anything and everything was fine until Holiday.
Can you please help me?
Pressing reset did not change anything. Sometimes, selecting reverse does activate the rear cam. That's it.
I don't know how to enter Recovery or how to install the Firmware.
It is an Android 9 PX5 System. This is everything I know.
Kind regards
Robin
May be able to reflash firmware using this method - https://forum.xda-developers.com/showpost.php?p=79144579&postcount=2 assuming that the manufacturer posts firmwares on their site, or can provide it to you via download, email, etc.
Thank you for your reply.
I tried some Firmware-files, just to see If the head unit enters Recovery. This failed.
The manufacturer also replied to a Mail, telling me that they will hand me out a possible solution next week.
I will wait eagerly.
Hallo again,
unfortunately the manufacturer did not provide a solution to recovery my Head Unit.
I managed to get into the Recovery Menu and tried to wipe data, but this had no effect at all. Still stucking in bootloop.
The information given in Rcovery Mode are:
rockchip/rk3368/rk3368
9/PQ2A.190305.002/hct204281503
userdebug/test-keys
Recovery V9.0.5.
Supported API: 3
Can anyone please help me restore the Head Unit?
Kind regards

Did you try to disconnect the main connector from the unit and leave it that way for a few minutes ?
And then reconnect it again.
Thanks for your reply... But I think I did very stupid today and bricked the device.
Reagrding to this topic "forum.xda-developers.com/android-auto/android-head-units/head-units-rockchip-px5-mcu-csn2-t3912413" I flashed my device with "Fake Android 10 - July 6th 202007061156".
The flash ran smooth without any errors. But the screen seems dead now.
The buttonlights still turn on and do blink if I press the powerbutton for about 10s, but there is no bootlogo or anything at all.
I cannot enter recovery anymore.
**** happens?!?
Kind regards
