Well I don't have a clue what might be wrong with the actual rom. When I have weird problems, I just flash another one... so let's try to address the bootloader problem.
Do you know exactly what is failing? Can you get into fastboot USB? Having trouble copying the token? A little more detail on that would really help. There are just so many things that could be screwing it up, but without knowing what you've tried, it's hard to know what to tell you.
