Need help loading original rom with sd card

[ayato]

You are doing things the right way. Now its just a matter of trial and error. First thing I would do is ensure the sd card you are using is 2 gb or less and has been formatted to FAT32. Put the NBH file back on it and try again. If that does not work, try a different sd card. I had to swap sd cards with my dad and his worked on my phone, but for some reason mine did not.

The last resort, I suppose, is to find another computer that you have access to and install activesync and the ruu on it. Do your business and then remove it from that computer. Perhaps a friend will let you borrow their computer.
