4) Outcome
It restarted, and keep restarting at Samsung start-up flash screen repeatly, can not load into mobile home screen.

I bought to Malaysia Samsung Service Center. They mention can try to flash my phone but not guaranteed. Worst still, Result:- black out, can’t start the phone even pressing power button.

Thanks, appreciate that

ps: I bought from Bangkok, is Malaysia version different? Btw, I did try to do the hard reset but same. (Vol Up + Home + Power button, then Wipe Data/ Factory Reset)
I screen capture baseband version is DXKF1, Build number is Gingerbread.DXKF4

Thanks alot man. Truly appreciate if any alternative solution or suggestion? If this USB Jig can guaranteed work on my case, I'm all right.
