I have a MS=25 and I had a hell of a time with MTKF freezing up with iPrep.
I read textbook.pdf and found pk's guide, I played around with my drive for a while and finally got IDump to work when I disconnect the power before selecting Xtreme Pri and quickly reconnecting it after I hit 1.
I dunno what MTKF does in those few seconds when I had no power to the DVD but with the Power connected it froze my system 100% of the time. I simply repeated the process to get it flashed.

1.) While running iprep 1.01 from USB key using idump batch. I had to manually pull the modulex from my Xeno connectivity kit a few times reconnecting instantly and spamming F3 until I got "No Drive Found" from the idump batch file (while power was connected)
2.) I continued spamming f3 until the drive was once again recognized.
Unplugged power on Xeno hit 1. to select Xtreme Pri and reconnected Power after a few seconds. It then read the original firmware no problems, finally after a day of serious messing around.
3.) To get iflash to work I simply repeated the above.
Drive is flashed and 100% working, thanks PK!
