will it be possible to unlock sc7715 NAND phones?

I used to unlock some SPD 8810 blu phones lockewd to DIGICEL, by flashing Generic BLU firmwares for same model.

tried this on 7715 by Read Generic firmware from phone and writing it to DIGICEL phone but phone is locked.

is there something I can do?

I have here right now both phones
the locked and the unlocked

and a third phone which is Locked and has the original DIGICEL firmware yet.

Hello. Read NVM from locked phone and send me for checking.
There is some way to unlock them.

Well, I solved the unlocking by writing NVM from the unlocked phone, to the locked one.

This caused the imei number to be cloned, so I tried to repair imei to the original and it didnt work in service mode, but worked in flash mode, with an error...

1. Remove battery. Insert battery back
2. Press and hold 'VolumeUp' and 'VolumeDown' keys
3. Insert cable

 ====  Wait for phone...

Don't mind about "error", it not mandatory. Will remove it in some of next version.

OK, I will fix the third phone.

This is not a real solution since one wont always have a locked phone to read the NV from...
