Gaining root acces/installing custom rom on G1 with build number CRC1 Could you please share your knowledge about how to flash the latest update of stock Android OS on G1 (aka HTC Dream)? I would like to try out some custom roms, but most information I was able to find relates to the RC30 or R33.
I think you will have better luck at the XDA developers forum

It's the main place for ROM cookers (mainly HTC devices), for the Dream follow this link.
