How to enter recovery mode

Note On older firmware versions, you can get a shell in recovery via UART, however it is heavily restricted due to SELinux. Newer firmware versions do not expose a shell via UART.

Hold down the OK+Back keys on the remote while booting to boot into recovery.

Alternatively,

  • Plug in to PC
  • Enable devloader mode in settings
  • Run adb reboot recovery

Note that OTG does not work in the recovery, unlike on the Mi Box 3.

How to enter fastboot

Note There is currently no known way to unlock the bootloader.
  • Plug in to PC
  • Enable devloader mode in settings
  • Run adb reboot fastboot

PCB variants

There are two variants of the PCB:

How to downgrade to older version of Android 9

TODO. The downgrade method used for the Xiaomi Mi Box 3 (xiaomi-once) will not work, as OTG does not work in the recovery.

"Multiboot" mode

Icon TODO: Write down instructions for this.

Implementing "Multiboot" mode (see Amlogic#Boot process) in the U-Boot environment via the U-Boot shell is needed to boot pm os but in newer revision of android 9 the uboot shell is being disabled so there are no way to implement this in newer revision.Sadly, there are no way to downgrade.
