Make a test with eepromtools and see what is damage. If it said cobba - failed, you must change cobba. If all are ok, then flash mcu+ppm+eeprom, then rebuild imei, then make resets.

cobba (or Audio IC, which signed V257H, V257B) is a small ic located at the top right of CPU (the biggest IC) If Cobba IC damaged, then SW can not detect the ID of it and it will show CS at ur LCD!!!

download that eeprom above thank him u can now know where to start...
put your 3310 using an mbus cable tick test!!! there u can see the prob..
like it would say mcu eeprom tune sum test failed....
cobba parallel or cobba serial..
if cobba serial - replaced cobba
cobba parallel - just reheat the cobba..
mcu rom......test failed... still reprog.. use an alternative flasher soft...
mcu eeprom only just tick the eeprom repair and faid that would be ok..

but if u have the guts try replaced the cobba IC of 6310 and 3310.. gud luck mate..
