Flash this in recovery and your main version gets set to a generic 1.00.000.0
This will allow any PH98IMG.zip or the newest RUU to run on your phone. I recommend flashing this before you flash a ROM that autoboots to install a PH98IMG.zip or before loading a PH98IMG.zip manually.
How to use: Just flash it in recovery as if it were a rom. Main Version Older issue will be solved.
Current Phone: Galaxy S3 16GB White on VZW
Current ROM: AOKP JB Build 4
