nexus 7 : twrp custom stock rom magisk root

Grouper = Asus Nexus 7 2012 WiFi
Tilapia = Asus Nexus 7 2012 3G

If you get “Error 7” when trying to flash the ROM directly after upgrading to TWRP 3.4.0, wipe the Boot, System and Cache partition and clean dalvik-cache, then re-boot to Recovery and try again (you will not loose any data as long as you do not wipe the Data partition).

Initial Setup Installation

  2. Boot into Recovery
  3. Factory Reset (only needed if you are not already on Android 7.x AOSP)
  4. Install 7.1.2 Grouper OTA-Package (Build 20200805) (md5: f5d3448d6839ab716c0a084f0125b388)
