Root gone wrong!

view story

http://forum.xda-developers.com – I have a P925. Unlocked it though IMEI, my proximity sensor was acting up, since the screen went off during calls and no button would bring it back. I checked the rest of the components on the same flex cable (camera, earspeaker, noise mic) and all work fine except for the proximity sensor, so i thought it might be a software problem. I rooted the phone and installed the clockworkMOD thing... proximity sensor still doing the same. here came the problem. i tried reseting to factory.... now the phone keeps saying 'not enough space, free some memory'... and phone app keeps crashing. what sh (HowTos)
