1. Thanks for the quick response.
2. So you're saying that while my carrier currently says T-Mobile, I should take the RUU_Signed.nbh from the No-Do AT&T stock rom for use?

Well, sticking another patch ove rthe wrong patch may or may not help, but yeah.

Unless you meant re-flashing the entire ROM, which would also work; there must be stock AT&T HD7S ROMs around somewhere.

hi i am trying this guide. done all it says but i am stuck at the (enter usb host mode) screen. the only reaction i get is when i use my 7gb flash drive, but even then it says ( not allow). i am using this on my hd7, sandisk micro sd with usb reader.
Any advice on what is wrong would be great!
Thanks,
Dan.

Probably you have branded device. You have to do downgrade process with ROM for your operator. Select one ROM from this topic: http://forum.xda-developers.com/show....php?t=1427890
