Well your really half way there if you have the meid repaired that's the biggest hurdle with that phone all the rest of the flashing is the same as the evo 4g. I don't think that you mentioned in your post that you were flashing it to boost mobile but for anyone else reading this and wanting to comment that is the destination carrier.

The error 16 that your getting is due to an meid mismatch error from sprint and that discussion has been exhaustively discussed search boost error 16 for more information

Hope this helps
