1. flash LATEST firmware version. that is first step and you MUST do it always.
2. if phone has imei mismatch or gdfs structure damaged (gdfs open errors) - reset phone.
2.1 if gdfs okay - do not touch gdfs, just do reset operation and write erom on emptyboard tab (that will fix secunits)
2.2 if gdfs damaged - write gdfs template, then write gdfs package from working phone, then 2.1
3. try to power on phone.
4. if phone does not startup, forget about software problems and search hw problems.
 
it is a SIM Rst failure. it come from both security fuse and power IC. first Change power ic. if no luck then reheat security fuse.
