Happy dude here... Method works...
Gear: A8N-E mobo, VIA SATA PCI card, MS28 Sammy
- SATA PCI card (Conceptronics) using SATA connector IN your PC.
- IDE DVD drive attached to SATA IDE port
- Make the bootstick using Xtreme Bootmaker using alternative MTKFLASH (autodetect) and other checkmarks checked
- Reboot: disable all IDE and SATA stuff (I left my devices attached), even LAN and ALL USB-stuff, just PS2 keyboard
- PC on: Boot from flash
- XB on: with SATA not connected in drive, and Video cable plugged into xb
- when XB fully started: put SATA cable in
- @command prompt: samread big ass (parameters are directory names...

)
- shows you some options FIRST TURN XB OFF
- enter option #
- wait 10 mississippis
- turn on xb
- 4me: did not write HACKED.BIN so I did it myself using ORIG.BIN which was in my big ass directory

- go 'x360sam.exe orig.bin xtreme.bin hacked.bin' and put the file in the big ass directory
- reboot: so xb off, cable detached, pc on, when booted, xb on, when fully on, SATA cable in
- enter samhack.exe big ass
- wait at option 'menu'
- turn off xb
- enter option #
- calculate 1825328 * 2838268
- turn on xb (xb flashes: 4 banks total: wait until says REBOOT PC)
Go have fun... have a beer...
