Reply To: Download and Install LineageOS 16 on Nexus 9 – flounder

Found this which gets rid of the password screen and Nexus fully boots up but is unresponsive to touch screen so is in effect locked up. Only Power off button works

Boot into Twrp and under Wipe you’ll find FORMAT DATA, not wipe data.. Format the data and the rom will boot . Note that you’ll lose everything from you phone, so it’s good to save files on pc before, if you have something important..

update — after further ‘hacking’ I now have a Nexus with only TWRP on it…… :-((((
