hi guys bit of help please, over the last two days my phone has been losing signal to the point where i get an icon of a sim card with a red stripe through it, first thing i did was try one of my back ups with no luck. Then earlier i flashed my phone(global pr1.2) still with no luck? i havnt messed with anything like overclocking or xterminal things because i just dont know what to do lol, any help to get my phone back up and running would be great

p.s on vodafone and have tried sim card in other phone and have full signal
