Hi: I have Samsung S3 Mini GM-730A (ATT); I noticed my 3G/4G broadband glitches really badly; most of the time it will show a circle and a slash on it. Also, sound doesn't work either. Troubleshooting steps taken: - re-flashed stock ROM via ODIN3 - didn't work. - factory reset didn't work. - must use USB cable charger via PC, not wall charger - it will kill signal right away, strange. - As long I don't powercycle my battery or shut down the phone, but only use the restart function, I will be able to get 3G/4G signal that will probably last a day or two at the most - rinse n' repeat. I am thinking about getting a new motherboard for my smartphone - it's only $25.00 on ebay. images hosting Thoughts?
