I have my boyfriends samsung galaxy gt-i7500. He has installed a new theme on to it which must have done something to the software and now when it is turned on the samsung logo just keeps flashing up. tryed codes (voldown+call+power) still goes into same loop cannot reboot. also tried (call+ok+power) up can get to that reset screen an then 19 but still does the same loop after turn on. I have tried connecting to pc to try and remove everything off the phone to try that way but pc is blocking it because it has a problem. please help. Thanks in advance.
