Evolution X Updates:

  • Evolution X on android 11 is under fast development to bring back features from android 10. Do not expect full feature set like that on android 10.

Notes and Known Issues:

  • Wireless Display can scan but may not connect successfully
  • “OK Google” hot word does not work yet

Flash guide:

  • After formatting data, you may have to reboot again to recovery
  • Wipe system & data & cache & dalvik cache
  • Install ROM
  • Reboot

Gapps are included. Vendor and firmware are included. Format data and clean flash are required.
