I have 2 360's, one with a ms25 and the other with an ms28. I've modded the ms25 one with the c4eva xtreme 4.1A and the other ms28 with 4.2A via 10 sec trick, (because i did that one later than the other that is why there are different versions).
I am using backups verbatim and memorex blanks burnt at 2x on both systems but seemingly the ms25 w/4.1A boots all these backups fine and plays them fine. But the ms28 w/4.2A sometimes takes a couple times for the xbox360 to boot the disc. i'd have to restart the box or hit the eject button twice for it to take it.
I was wondering if anyone else had this problem with the ms28 or with the 4.2 in general. I noticed the only difference in booting 4.1 and 4.2 are with SS and PFI's read in different order, could this explain it?
I'm thinking about just leaving the 4.2 as it is because the backups do work just take a couple times to boot (quite annoying). and wait for v5.0 (haha).
Great work c4eva.
