...fullflash your phone with good fullflash file (include bootcore area), unlock your phone with ReCalculate all keys.
Search on this forum, you have more explanation inside.

I write full flash with Dreambox . How can you ReCalculate all keys while OTP Imei is empty ? When i write full flash with Dreambox , phone turn on with "Wrong software" , if i unlock it with Dreambox , phone can not turn on anymore!
 
Prototype?
Write new Bcore with Papua Utils (Flash Tab)
Make Freeze with Papuautils (Read OTP IMEI before) (Various Tab)
 
...hmmm,
if you write the new bootcore area, never (forever) you not will make the firmware upgrade and (or) flash again your phone. Other risk is to appair "Hash: FFFFFFFFFFFFFFF...". So, I suggest to fullflash your phone using X65flasher with MS-DOS command "x65flasher /b" (disable bootcore area protection) and use testpoint. After fullflash, open Papuautils, go to the "Flash" menu, check only "??????OTP", "Pause" and all from "Recalculate Keys". Click on "Do the Job!", make testpoint (disconnect after ignition in three seconds) and wait to finished.
I used this methode manny,manny times to repair death S-Gold phones.
BTW: OTP IMEI is writed in the ROM area from the phone microcontroller (in the manufacturing process). Is too hard to erase or change it.
