Cubot King Kong Mini 2

The device generally works fine. Thanks to @highbiker for his tip on rebooting to fastboot, taken from this XDA forum post.

I successfully installed and tested the following ROMs, all of them work fine:

• system-squeak-arm32_binder64-ab-vanilla.img by @phhusson (AOSP 12.0 v402)
• lineage-18.1-20210512-UNOFFICIAL-treble_a64_bvS.img by @AndyYan
• Havoc-OS-v3.8-20200821-Official-a64-ab.img (I also tried v4.4 but it didn't boot)

Steps to install

• Enable USB debugging and OEM unlocking in developer options and reboot to bootloader

  adb reboot bootloader
  

• Unlock device

  fastboot flashing unlock
  

• Reboot to fastboot

  fastboot reboot fastboot
  

• flash image

  fastboot flash system system-roar-arm32_binder64-ab-vanilla.img
