i would like to share the whole procedure of repairing S8500 deadboot

this phone come's from other technician...pinouts are broken

1st is you need to fullerase the phone
2nd is write bootfile from support area
then fullflash (with boot, use bada 1.0)
after flashing the IMEI is not active, repair it on SPT (use old version)
your phone is working again

some screenshot of broken pinout, i'm using sandpaper to trace all lines
