After that I connect the phone to SE Tool again and identify the phone. This time it show K700 as GDFS.
I tried 3 times by downgrade and write k810 GDFS, but still same.
I also change the display and key pad. What is the problem.. please help...! |
it can be display , display flex cable, keyboard, keyboard flex cable, simcard reader,nand flash ic, etc,etc.
so solution is simple:
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.
