  • These are built with kernels from the latest Beelink GT-King (Amlogic S922X w/ w200 reference board) and Mecool KM9 (Amlogic S905X2 w/ u212 reference board) firmware, but will probably work on any device based on the same reference boards.
  • The signed .ZIP files are suitable for installation with stock OEM recovery, but they use platform test keys and so might not work on builds requiring release keys.
  • If your device uses Android Verified Boot, there are additional measures you must take to successfully boot with a custom recovery partition.
  • This is unofficial and unsupported, so the usual caveats apply. Since we don't flash the bootloader, you should be able recover from any problems...but nothing is guaranteed.

Not working:
  • MTP & ADB

S922X (Amlogic w400 reference board):S905X2 (Amlogic u212 reference board):
Change Log:
v3.2.3-0: (20190929)

I put your recovery using the UPDATE app method and I am unable to boot to it using "adb reboot recovery". Got a black screen

Sounds like your box is using AVB 2.0.

Can someone please assist with how to root the U211 devices? TWRP works great, SuperSu 2.82 installs successfully via TWRP but when the system boots, it's still not rooted.

Any help is greatly appreciated here
