Now, it only load android (installed in emmc)

I have create other new usb with coreelec (9.2.3/9.2.8) with renamed dtb. I shutdown the khadas and press power button, the push reset and release power button after 5-10 seconds, but it only show Android Recovery Screen.

I do not know if i need update android to the last version. I have donwload it but how i update it?

I need help, thanks

You do not insert coreelec boot disk. Can the Android system enter the desktop normally?

I probe the same usb pendrive (with dtb changed) in gt king tv box, and the coreelec start correctly.

Android work perfect.

In khadas, only show Android Recovery screen, when i use the upgrade sequence

  1. Power on VIM3.
  2. Long press the POWER key without releasing it.
  3. Short press the ‘Reset’ key and release it.
  4. Count for 2 to 3 seconds, then release the POWER key to enter into Upgrade Mode. You will see the sys-led turn ON when you’ve entered Upgrade Mode.

What can i probe?

  1. My andorid firmware is http://dl.khadas.com/firmware/VIM3/Android/VIM3_Pie_V211220.7z.
  2. My coreelec firmware is https://github.com/CoreELEC/CoreELEC/releases/download/9.2.8/CoreELEC-Amlogic-ng.arm-9.2.8-Generic.img.gz.
  3. Copy and rename vim3 dtb to dtb.img.
