and then repair using smart clip

Bla bla bla... You can't change CPU only! You must change Flash chip with CPU and than flash it with image file and your phone will be alive.

@pecel : so you mean that flash ic contain unique code which is OTP, so when i change cpu then i must change brand new flash ic (like uem in nokia) ???, btw i'll try your suggestion then post result here
thanks for reply

Yes, that's it :

- You can change flash ic and then flash it with _flash file, because you have OTP in CPU

- You can change CPU and flash ic and then flash it with image file, OTP will be created, but you can write original number from sticker.
