[Q] Unroot phone with upgrade - Galaxy S Relay 4G
I buy a Galaxy S Relay 4G, I first unlock the phone following this thread http://forum.xda-developers.com/show....php?t=2255892
, root with this thread http://forum.xda-developers.com/show....php?t=2787068
install clockwork and make a backup, i use one time this backup and it works fine.
My problem is one day my phone ask me to upgrade to another version of rom... Cause i'm afraid it lock again the phone, i decline, and then he ask to upgrade everyday, and one day, i "missclick" and then the phone reboot and began to make lot of operations.
Two times he ask me to flash the rom and i say no the two times, then he start again but clockwork was removed, root removed, and the phone is on the same version...
Since then, he doesn't ask me to upgrade, but i canno't root the phone with towelroot... I doesn't understand why...
My phone has some lags so i want to revover my save...
My questions are:
- Can I reset the phone to reroot him ?
- It seems that i can make the upgrade keeping my phone unlocked, is it right?
