Avdude.. I figured out a fix. For some reason we are both having this problem when trying to do the USB flash. Do this instead.... It worked perfectly..
1. Format the 512 micro SD card that came with the phone using Fat32
2. Decompress the leaked Rom onto this card.
3. Rename the file 2.nbh to VOGUIMG.nbh (be carefull as there is a 1.nbh and a 2.nbh) you want to rename the larger 2.nbh file
4. Insert card and do the power/camera/reset boot sequence
5. The phone will now flash the ROM from the Micro SD card and not the USB cable... works perfectly this way.
6. Enjoy version 3.37.15
