First, i'm a noob.
I decided to flash KitKat as I play a WebView based game and thought the WebView Chromium of KitKat might make it run faster as it ran pretty slow. On the Paranoid Google+ page it says you need TWP 2.6 later and other sites say 2.6.x. I had 22.214.171.124, so did a backup of boot, data, system and recovery, copied to PC and then tried installing KitKat, it failed. So I updated to TWRP 126.96.36.199 and it failed again, tried a second time and it updated.
The game didn't work well on KitKat, so I restored my original version. I then decided to take screenshot of game not working on KitKat to complain, so tried installing KitKat again forgetting to update to 188.8.131.52 as the restoration of the backup restored the prevous 184.108.40.206 recovery, was a noob and tried again and i'm now left with a Nexus 7 in a boot logo loop.
Restoring the backup fails, as does installing the KitKat Zip or Opensensation . If I try flashing TWRP 220.127.116.11 via fastboot, it says success, but when I reboot the recovery i'm still in 18.104.22.168. I can boot into 22.214.171.124 using "fastboot boot", but it still won't restore the backup or flash. I also have a backup of the OpenSensation rom (wanted to try PDroid and it was the only rom I could find prepatched) which I made on 126.96.36.199, that won't restore either.
So now what do I do, as I don't want to make things worse. I am doing a factory reset before installing. The error i'm getting is "symlink: some failed"", "can't open destination log file: '/cache/recovery/log'" and "E:Unable to open '/cache/recovery/log'"
I'm sure this is not what you want to hear but if all else fails push the factory.IMG you will be starting from square one. You can try pulling your backups off but might as well start over for 4.4
If I or someone has helped you don't forget the "Thanks" button!
