1. Get TMF's tutorial you can find it here:
2. Choose either method 1 or 2 (I choose method 1, method 2 seems easier (not for n00bs) but after taking away the glue I noticed the the pins on the fw chip look very small and weak)
3. Download Dosflash 1.2 by Schrtom you can find it here: (http://rapidshare.com/files/54510344/DosFlash_V1.2Beta.exe.html
4. Extract the files and put them onto a floppy disk/usb/whatever
5. Set your computer to boot the floppy/usb/whatever before any other drive
6. Once the floppy/usb/whatever has loaded "A:\", type in "dosflash" (without quotes) BUT do NOT hit enter
7. Make sure your SATA cord is plugged in, your 360 plugged in, and your switch set to "OFF"
8. Turn on the 360 and when ready (not immediatelly wait at least a second) flick it to the on position
9. Hit enter ! The drive should show up under option number 4 (if it doesn't power off the 360 and go back to step 6) with some other stuff and you should see "MX25xxxxxx"
10. Press 4 and enter, press R and press enter, type "orig.bin" (without quotes) and press enter - wait until all 3 banks have been read ("Bank 0....OK 1, 2, 3)
--If you can't get your drive to show up after many tries and your sure everything is 100% correct, start at step 6 but use the command "dosflash r yourportnumber
1 A0 1 4 A:\orig.bin" (without quotes) - example of this command would be "dosflash r 14B0 1 A0 1 4 A:\orig.bin" (without quotes)
