This thread is about installing and using AOSP 7.x (Nougat) ROM for the ASUS Nexus 7 Grouper / Tilapia devices.
Asus - Model names
Grouper = Asus Nexus 7 2012 WiFi
Tilapia = Asus Nexus 7 2012 3G
Initial Setup Installation
I was not able to flash Magisk 24.x by TWRP / direct install, nevertheless the patching boot.img method worked. For that you need to extract the boot.img from the OTA and transfer it to your devies. Then you need to patch the boot.img and transfer it back to your PC. Finally you can flash the patched boot.img using fastboot.
For detailed instructions please consult the Magisk threads here in XDA.
Do not install Magisk on initial setup as it might lead to issues. Start the ROM without having root access the first time and install Magisk in a second step.
If you are already on Android 7.x AOSP, it's sufficient to do the follwowing steps:
Update Installation
Important: For more detailed installation instructions please refer to the next post
Important: First boot after upgrading will take a bit longer (stays on ANDROID) because of art optimizations
flash and use on your own risk!
