My gs3 r530u -4.1.2 MD4
problem was phone data show 1x
But i changed it to NV mode ( 3times till accept change )
So 3G works well now. Feeling better
.......
Now just only the problem is : cant answer International calls ,
I flashed ( mb1, Lk1 modems) but nothing changed.
Should i downgrade to ics ?
What if i update to the latest (during nv mode)?
With regards
