I bought this tablet 2 months ago in our local t-mobile. And everything was fine until 2 weeks ago when it suddenly started loosing gsm signal.
At first i thought it had something to do with me rooting it. So i tried repairing it 2 times but with no luck. After that i tried downgrading to 4.1.2 and that didn't work either.
So basically i can be online (surfing,downloading etc.) for few minutes before it drops gsm signal (no signal icon in statusbar) and after few minutes it comes back and then it drops again...
I'd like to know if it can be fixed without taking it to nearest sony repair service. Did anyone encounter similar problem and manage to fix it?
