I dont have software like that. I even if had something like it before, it's not running now for sure! When my drive arrived with UL01 it was RPC2. After flashing with UJ12 it became RPC1. Since then, anything i flash or do, it stays RPC1?! Very strange.
But i have some expirience with flashing the MTK based DVD (home) players. And once you flash it with Region 0 firmware, every firmware you flash after it, it will allways stay region 0. And that is because the region value is stored in EEPROM of the player and it is not in firmware, but you can change that value by setting the right value in firmware that will tell the EEPROM to change the region value and keep it that way.
