You are imagining a far larger problem than you probably have.
I'd guess that your friend has screwed up the dash, not the TSOP. Get hold of a rescue disc (e.g. HeXEn - Google Heimdall's Xbox Engineering Disc), burn it to DVD-R at 4x or slower, and boot with it in the drive. It will load, the LED will turn red, and you can restore the dash with FTP - try putting one at C:\evoxdash.xbe - or use one of the HeXEn options to rebuild your hard drive from scratch.
FYI, softmods don't ever work on top of a flashed BIOS, so Kingroach NDURE was never going to work for you.
hmm thanks nice to now that ndure won't work.
I can't boot any disk tried AID slayer 2,6 2,7 got heXen will try this.
those boot fine on my softmodded 1.6 tried with that dvd drive over in 1.1 to.
tried to put files to xboxhd with FAT-X-Plorer. from windows 7 It only succes partly. stops answering.
will it only works if its named and placed C:\evoxdash.xbe?
