This is my current situation and wondering if it's still fixable:
Phone is RELOCKED,Unrooted but S-off. Stuck in a bootloop where it stays on the Splash screen no matter what rom you install. FastBoot commands give me FAILED (remote : not allowed), tried re-using RUU but I keep getting Error 120: BATTERY under 30% while my phone battery is at 84%, I'm stuck and don't know what to do anymore.
and yes, I can still use recovery TWRP.
Any suggestions? Please and thanks for the help.
