Here are the details ...
Nexus 7 gen 1 2012 Android 5.1.1 rooted and unlocked bootloader
Using cwm as my back up
Kernel to flash.. Timur's kernel .
This is my first effot playing with kernels So I maybe missing something but here is how I have proceeded so far ....
1 root tablet and unlocked bootloader using root my Nexus by wug fresh
2 download the kernel from https://timur.mobi/timurs-kernel-n7-2013/
And then move two zip files over to my nexus
3 enter cwm recovery and flash the kernel from there
It just doesn't look to be install I have emailed the developer confirming I have the right version for my Nexus (am waiting to here back )
Any help would be great .
