I have a PX6(1024x600) that is stuck on the Android logo animation screen after I accidently updated from Android 10 to 11. It will not go into update mode regardless of what I try. I've tried all versions of suggestions from all the threads including:
- Updating from USB formatted to FAT32
- Updating from a 128 SD card formatted to FAT32
- Updating from a 64 SD card formatted to FAT32
- Pulling the car's negative battery post, holding down the reset pin.
- Pulling the units power, waiting, plugging it back in and using the reset pin.
- Pulling the units fuse, waiting 1 minute, using the reset pin.
- Holding down the reset pin until the controls flash blue
- Holding down the reset pin until the controls flash blue, letting off the reset pin and holding it down again.
- Every possible combination of the above with 20 second waits, 30 seconds waits, 2 minute waits... nothing will get this to boot into recovery mode or start the USB/SD card update.
Before Update:
- Build number rk3399-userdebug 10 QQ2A.200305.004.A1
- Kernel version 4.19.111+
- MCU version MTCE_HA_V3.45_1
After Update: flashes the Android 11 boot screen and then goes into endless Android logo animation.
Is there a software tool that can flash this from a UART header, USB or other? If so where do I get my hands on this?
