Guys, need some help.
My friend's unrooted S3 had some problems.
1. Installing some apps wouldn't work. Error 24
2. Installing new apps work.
3. Tried to update the phone through system update as she's still on 4.3
4. Error trying to install it.
5. Bootloop occurs. Can't get pass boot screen.
6. Removing/reattaching phone boots up the phone automatically.
7. VOL + & Home & Power button to recovery doesn't work as it's always stuck on bootscreen.
Any other method to factory reset without PC?
if can't boot into recovery most probably u need to flash back stock rom with odin.. n yes, u will need a PC..
