Today, I was going to flash a Samsung MS25. After a few attempts, I got my USB boot up and running, using Xtreme Boot Maker 0.5.3, (applied the update for the new firmware) and Xtreme 53. I startet up from the USB in DOS, and startet reading and flashing. No problem at this stage. When I attempted playing a backup game (which I know works) I got the "put in a 360 console" message. But I also got the same message putting in original games! When I tried flashing back to original, my computer hangs on the fa00 and master/slave b0 (a or b depending on my choice, master og slave). Ive tried shifting sata port on motherboard, both xtreme master and slave, when having to choose port, and ive also tried, just to see, what happens if i try to load up the Xtreme Boot Maker 0.3.x with Xtreme 52. No mather what, it hangs there. I used the firmware from xbin for this samsung drive, i made sure it said ms25 in the XBM, and it said everything was ok. Why do I get stuck at this stage now, when it worked excellent the first time, and what can I do to install the right firmware, or atleast the original firmware, so original games will work? I have a native SATA, using NVIDIA chipset (which I selected in the XBM). Ive also disabled all drives and hdd`s, so the only thing connected was the Samsung. Xtremely thankful for all help!
