Hello everyone,
I have PX6 RK3399 Android Car Headunit without any psyhical buttons(except RST). I by accident i flashed wrong update.zip(A11 not A10) and my headunit got bricked.
SOM is HCT-RK3399-REV08
I readed a lot of stuff on XDA forum, and found a MASKROM mode, so i tried.
Here is a list of equipment which i used:
- Laptop with Win11 and USB3.0
- Laptop with Ubuntu 22.04 and USB3.0
- Laptop with Win7(x86) and USB2.0 and USB3.0
- OTG cable with 12k and 15k which i connect to SOM board
- Male to Male USB cable and connect it to both ports on Headunit
After several tries i already built good cable and get into MASKROM, but i can do nothing there, everytime i got errors on every device which i mentioned above.
Here you have LOG from RKDevtool v2.65, where i tried to “TestDevice” or “Upgrade” a firmware for HCT_Rk3399_8.1.img
