    1. Try unlock and show log.
    2. Check may be new nv_data backup will be created and attach.
    3. Read EFS.
    4. Open CERT and edit imei there to your original.
    5. Write CERT to phone.


    if phone will work this can be bug in samsung firmware.
    if firmware now and before 1st unlock not same, may be user played with something and did some changes in EFS.


    anyway do all steps and tell me result.
