~ I've unlocked the Nexus 7 okay
~ I've installed and confirmed I have TWRP running and ready to go
~ Downloaded nAOSProm-7.1.1-grouper -b05.zip (wifi only N7)
now I'm a little unclear as to next assume I should:
~ Use TWRP to backup current working stock 5.1.1 image
~ Copy zip across to N7 using fast disk similar to when copying twrp over
~ TWRP Clean Wipe?
~ TWRP install?
~ TWRP Reboot and cross fingers?
~ Done N7 hopefully running Android 7
Just want to check I've got that all straight before I stuff something up so thanks for any help and replies
