After a certain update the MS25 becomes a MS28, so there's no need to spoof it as a MS25, hence there's no LT2.01 for MS25 drives.
Just flash it as if it is a MS28.
EDIT: Did some research, but I can't find a definitive answer.
Fact: For pre 13141 there's a MS25 and MS28 OFW, post 13141 there's only 1 OFW for all Samsung drives.
Fact: LT2.01 is for all Samsung drives, and AFAIK you need to insert the key manually, no spoofing.
Fact: After a certain update a MS25 drive will show up as a MS28 drive spoofed as a MS25 drive in JF.
I could be wrong, but hey, MS25 drives are pretty rare.
