Sorry, this thread is for CarbonROM-related discussion (which according to above, you did not install). With that out of the way...
Pretty sure you need original recovery in order to flash the original ROM. As for finding the TW version, I haven't the foggiest. Maybe there is something in general or you can ask in Q&A?
Yeah, I had to use original recovery to install original firmware, that's why taro wasn't working. Now problem solved. Thanks
