| Hi, the problem in addition to the unknown IMEI you also have the unknown modem part.
Having the unknown modem does not allow you to write the IMEI code.
So you have to make back the modem part correct and not unknown
You can try to write another firmware until the modem part returns correct and then try to rewrite the IMEI code
Or if you are writing different firmware you don't find a solution and the modem part remains unknown, you can try to write the security of your phone if you have backed up your phone's security with the program, or you can backup your security, try Write the security and see if the modem part returns correct and not unknown and see if the IMEI code returns to default and then try to write back the IMEI code |
