Hi all,
I purchased a PR7846B Xtrons 8.1 head unit for my BMW 3 Series back in February. All was working fine until I tried to change the boot logo to have the BMW logo instead of xtrons. It now gets stuck in the boot loop and I’ve been struggling to find help. I got given an update file from the manufacturer and tried to install it through their guidance however even though it says it successfully updated, it immediately goes back to the bootloop.
Please help me fix this, I’m no tech expert and don’t know what I’m doing with this. All articles and help are showing phones and as you’re aware, there’s no volume button on this so you can’t replicate the steps exactly.
I’ve got videos and pictures of what the update process looked like when I tried it, appreciate the help in advance!

Good day all!
I am in a bit of a bind... I have an AOTSR A764H Android 6.0 head unit which is stuck in a boot loop so I cannot see the MCU. Took me a week just to track down the make of the head unit. What can I do to fix the boot loop issue?
Please help!
Hi all,
I have an Xtrons PST10HDT head unit for my Toyota Highlander, that runs Android 10, with a MTK Quad core Cortex-7, 2gb RAM, 16GB ROM. A few days ago I noticed when I'd start my car it gets stuck in a boot loop and stays on the Android loading screen. I've tried the power/reset button in every combination possible, to no avail.
I've reached out to Xtrons and they pointed me to their forum that yielded nothing. So I came here. Does anyone have any insight on how I might get past this? I imagine I'll need to flash a new ROM on it, but I can't find any information anywhere.
Thanks.
Hey!
My head unit is stuck in bootloop. It's an xtrons Android 10 PX6 unit MTCE_GS_V3.67_3 (Nov 7 2020).
I tried to flash Hal9k with the modinstaller downgrading to Android 9. Got stuck in bootloop.
That can happen. So I went back to Android 10 again and installed CHS2_RK3399_10.0(20200424)img via SD - stuck in bootloop.
I have access to recovery though and tried wipe cache and factory reset.
I tried to find help in old threads, pressed with 5 fingers on the screen during boot-up, and tried tapping on the screen.
The unit is connected to a DC power supply on my desk and I always disconnected power between all tries. No success.
Any more ideas?
Thanks for your support! It's well appreciated!
I have a similar issue with Ownice C800 PX6 rockchip 3399, i changed an option on the setting to have it default to off instead of On, after it rebooted nothing shows up on the screen. i can access the recovery menu and did a factory rest and nothing happens, i installed
Malaysk ROM for PX6 RK3399 with Android 10 and the update was successful but still no boot at all, the recovery log shows failure to create file in memory. not sure if the setting made the memory protected and why the boot is failing.
My apologies previous threaders I cannot fix your bootloop, but have similar problem.
Question to bluefreak, how did you get into recovery mode?? from a bootloop??
My original item is a 4gb ram 64 gb rom, px6 unit, previously I put a russian rom flashed via update to system on it, I think I paid 20 usd for it and it worked a treat until my son used the car, several years past warranty. And it has gone into bootloop.
I think the flashed rom was Malaysk?? I may be wrong.
I have a reset button, held it in for a minute still bootloop, connected another rom via usb and it will not flash, just bootloop. I have also attempted many methods from google and youtube.
Good Day XDA.
Guys i have a problem and need some advise and help, i downloaded what was to be the latest system update to fix the Radio app no sound since i bought the unit.
flashed the System update all went okay - Android rebooted and completed its setup and was prompted to restart for the settings to take affect.
and boots up into a black screen no boot logo nothing.
i plugged in a USB keyboard and can snap photos so the unit is on and working i assume the System update messed up the Graphics display.
is there anyway to get this T3L into recovery mode to Flash the Original System update again to fix this problem?
please anyone with any ideas or tips and tricks i would be very grateful.
Thank you guys
hi, everyone, I need some pointers on how to fix this device, it was working fine for about 11 months until it got stuck at the boot screen, the seller says it is a mainboard issue, but have not even the slightest idea on what might be wrong.
if I make an SD update card, the logo displayed at boot changes, but never gets past it, i have no idea on how to make it go into recovery mode, or where to connect an usb cable to connect to PC
anyone else faced the same issue?
