Both flash files i posted, tested on 100% working phone,

Results:

- After writing file from second link - black display on power on, but sound can be heard upon booting.
- After writing file from first link, phone booted up normally,
imei and baseband ok, network okay.

So ... imei problem is not in the rom. Either is a hardware issue,
or already corrupted nvram area.

I attached .qcn backup fixer. You will need diag port enabled,
to make backup qith QPST, and through attached SW to fix imei, wifi, BT addresses.
(try to enter test menu - on powered off phone, hold volume up + power on key, menu should appear, then connect usb cable)
