Ok on.893 I safestraped and forever rooted. When.902 OTA I had to goto 893 backup and update all was fine and installed. When 905 came I tried to dl/install it failed install and when it rebooted I had no data or cell tower but I had Wifi. I had a bricked phone all day at work. When I got home I was able to dl and install 902 and got my cell and data signal back,from there got 905. Well I had a problem and phone locked up so went back to 893 and did same thing with no cell or data so hooked up to Wifi to do same thing but while in the middle of install it fails. So I'm on 893 with no cell or data. I'm still rooted and get wifi. My question is what's the easiest way to get 100% stock with no root. When I master resets it keeps root but no cell or data. Please help asap
