Hi all I've got a very weird problem with a GT-I9100, I bought it cheap as it was stuck in a bootloop, spent all morning flashing and re flashing it, tried PITs bootloader, official firmware, different kernels but no matter what I tried it wouldn't get past the black model number screen, so I emailed the seller and asked how it happened, he said he got to work one day listening to the radio and pulled the headphones out and the phone restarted and has been in a bootloop since, so having read that I grabbed some headphone plugged them in and it booted up into the last OS I flashed (stock 4.0.3) in this case, so i pulled the headphones out and it just freezes, but if I put the headphones back in it carries on working, so I thought no problem I'll just replace the circuit board that has the headphone socket, so I did that but the phone still behaves in the same way, I also tried detaching all the cables except the one to the screen but it was stick stuck on bootloop, any ideas? its had a full flash, new PIT, bootloader, and full stock firmware, plus a new headphone socket circuit?
EDIT: I've just found that if I pull the headphones out and press the applications icon nothing happens, but it stores that interaction so as soon as the headphone pin touch the headphone socket it then goes into the applications menu
