Hi,
I have a PX6 STM32 RK3399 - it was running the standard software that it was shipped with.
I did a 'Reset MCU' from the standard menu in my head unit to try and clear all the data from it. Unfortunately it didn't work. It started getting a corrupt boot logo then going blank. After many reboots it is now blank all the time. I can see the backlight is on, which goes off when use a pin on the reset button, but that is the most I get. I have tried holding down the reset button, trying to power/volume up buttons but nothing works. I had a look at the PX5 bricked thread, but I dont seem to have the pins which he has.
Are there any other ways to fix this? The USB doesn't seem to be powered/enabled.
Thanks.

Hi there,
After doing an upgrade my unit it stuck with a black screen and need to get into recovery mode in order to reload a working firmware.
Anyone any idea how to get there?
Tried the reset button for some time with and without home or on/off button and also removed the power source and pressed reset while putting power back but nothing seems to work
So i'm stuck for now :crying:
Any help?
Did you ever get your unit fixed? Did you try restarting with a USB plugged in with the firmware file on it?
No sorry... never got it working again. Had to send it back for a replacement unit.
I've been doing a lot of back and forth with their support on another issue and I've updated my MCU and software so many times now I thought maybe I'd be able to give you a hand.
Do you use any navigation apps on your Avant4? When I use ones that have voice navigation, the voice is getting truncated at the start and end of the directions. Some apps more than others and it seems to be related to those apps that use TTS (Text to Speech).
I'm using Waze via Android Auto. So i'm not having this problem.
So it runs from your phone and just displays on the Avant4? I have Waze running on the unit directly and it gets truncated.
I have al running on my phone and use a Android Auto box.
U can buy it from Avin USA. See website for all options on your Avant4.

If you hold the volume knob until it starts blinking then let go and hold it down again it will boot the unit into recovery mode.
I have an Allwinner T8 which had been working fine until yesterday. It's running stock firmware and unrooted. Yesterday coming home from work it started to boot loop. The radio would come on for a few seconds, then go off, the display constantly shoing the turning android.
I had hoped it was just hot as it was a very hot day, but was the same this morning. I've tried pressing the reset button to no avail, it just no longer plays a radio station as it's lost the stored stations.
I cannot seem to find a way to get into recovery mode, tried plugging in a USB keyboard and pressing "i" and CTRL-PrintScrn but nothing.
Can anyone offer any advice before it ends up as landfill?
I have the same problem with an Allwinner T8 team.
I have a 2016 jeep renegade sport plus. Supposedly the android team is a winca S300.
And it was in a loop, it does not start the system and it stays in the android logo.
I saw a way for the system to update itself.
1) the key must be connected - without starting - just making contact - power -
2) when the device reaches the android logo, it must be reset.
3) When the equipment is restarted, before the logo appears, the ignition key must be turned and removed.
4) After that, the start key must be reconnected. This should bring up an update banner.
The problem is finding that software, which should be previously installed on a flash drive.
Does anyone know how to get it?
I just purchased a px30 head unit advw9010.
It ran good for about 30 minutes and then the entire row of keys stopped working, i think the reset button is dead too.
When i went into factory setting the keymap does not recognize the key presses, when i went to exit it said it needed to reboot, during reboot my delay power may have turned off but not sure.
Now the system is stuck in boot loop
It displays the main start screen briefly, blinks the button lights 3 times and reboots after a few seconds.
Key combos and rst button does not seem to do anything as i expected.
Is there anyway to get this out of a bootloop? Or am i stuck with a $200 brand new paperweight. The seller is not being helpfull at all
post system info, MCU version and read through forums
The only info i can get is through the sale listing. The unit does not boot so i cant see the mcu info unless there is another way? Its a px30 quad core 2 gb ram 9" screen with android 10
I have been looking on forums the last few days but cant find any relevant info on my unit, and since the button row and reset doesnt work im stuck
Update:
The seller is finally helping out, i will get the firmware sometime overnight.
I dont think it will help with the row of buttons not working but i will update this accordingly and post the mcu and more details as soon as the systems back up and running
Hey all,
So i have this android 8 Secaine head unit in my truck. Yesterday it booted and failed. It shows try again and factory reset as options. But none of the touch buttons will move the selection. I plugged in a mouse and can scroll up and down but it will not activate either selection. It was working fine the other day. When i press the reset button it will reboot show the navigation software logo then go to the screen i have attached a photo of in this thread.
Any Ideas ? Is this a hardware failure ? Can i use a jump drive to re-flash the mcu ?
Thanks.
Well, there are 2 points visible...
Try again
Factory data reset
Seems you need to try the second one in this case.
It is written in the yellow colored part how to switch and choose.
Yes i saw that but nothing you touch on the head unit will move the selection or allow you to enable it. The touch function on the radio is gone. I can how ever move up and down the 2 options by plugging in my mouse, but clicking on one of the options does nothing.

If you don´t have physical buttons, take some USB-keyboard and use the arrow keys and the enter key.
Going to try that this weekend and cross my fingers. I have a few MCU's that are specific to this model i can try to flash if i can get it to factory reset. Just hoping the hard drive hasnt failed or the Rom is ok. It has been hot here this week.

Just get it out of the car and on your desk, connected to a 12V power supply.
That is nothing which should be done in the car, at least not if it is hot or stone cold.
