as far as i know you must have your original for the samsung drive.
I e-mailed it to myself put it on a thumbdrive and a partition lol, anyways if you get your original back by some miricle
set it up just like you would if you were flashing it with xtreme52 or w/e
but when it wants you to put in xflash or xread or w/e
type in mtkflash w /m /sata orig.bin (for ms28)
I have never done a ms25 so im not 100% sure on this but it should be
mtkflash w /m orig.bin just leave out the sata part, if im wrong lemme know.
