Root Repair Corrupt, Bad or Incorrect MEID/ESN Number

I have a Sony Ericsson Play r800x that I just bought and the MEID says A00000000000000, I tried using DFS and writing the original MEID on the label back but it fails to work. Is there a way for me to correct this? I am not sure if it is an issue on DFS of putting a password in, I did the SPC 000000 and it unlocked it but no change. Also my Bootloader is unlocked.
