Hello, all,
I got a phone S4 GT-I9500 Using MT6577 Chip BB and MS-ICS2 Magcomm77_cu Board. I have three problems:
1. Wifi is very weak. Distance to get wifi signal is very low.
2. Can not flash. I have tried many ways but failed.
3. The battery was very weak. Did not last long.

So far the only 'root' which I managed to do this with 'Root_with_Restore_by_Bin4ry_v18'

who can help me solve this problem. Please Help me?
