Trying to Update my Nexus 7 (Wifi) to 4.4.3 using TWRP
I got the notification and it went through the steps of downloading and rebooting. It starts to install for like 5sec, then the screen switches to the TWRP main screen. I tried using Wugfresh Nexus toolkit before to root my Nexus 7 and that was easy enough. I tried to unroot and flash stock recovery and failed. I don't know what to do, I dont care about losing root, in fact I regret rooting it in the first place. I'd rather get it back to stock so I can update............PLEASE HELP!!!
