The difference between the *.bin / *.hex file format and *.srf is that srf can deal with non-contiguous ROM areas, whereas *.bin / *.hex cannot. RR unfortunately cannot read srf files at this stage.

I would use Ecuflash to correct the checksum - there was a discussion on the BRZ thread over on the RR forums how the checksum is calculated (it's significantly bigger than the older roms, and required some code changes).
