Cannot flash ROM to emmc

ROCK 4 Series
1

Yesterday, I successfully flashed my ROM via Case 4: Bootable SPI flash, Bootable eMMC module. I did it about 20 times.

But today I cannot EraseFlash or Upgrade FW.
My steps are:

  • Use cable to connect PIN23 and PIN25
  • Power off the board and remove eMMC module
  • Plug the USB Male A to Male A cable to ROCK Pi 4 OTG port (the upper USB3 port), the other side to PC
  • Power on the board
  • Plug NOT Empty eMMC module (I have only one eMMC)

One possible solution is to put emmc in a USB emmc reader and format it on a PC or flash Android 9 gpt image with etcher and then try again with AndroidTool to flash Android 10.
Also you must use AndroidTool v2.67 or v2.71, v2.3 is too old to flash Android 9/10 and will cause problems.

FactoryTool (Restore) can also flash
