Note : This update is for the 2nd batch of T2e (SN:2021; Emerald)

** Warning **

  1. Please backup your data before proceeding.
  2. Not for the faint hearted. This is Beta software. If something goes wrong, you might lose your data and might have to re-flash factory Android 11 using SP Flash software.
  3. Few apps might not be available in the App store like Netflix, Disney+ (this is due to the build not yet certified by Google). Install them before hand to continue using them.

This is mostly a security patch update on the factory OS version (Oct 2021) with few minor changes. Certification is in progress.

What is new
