I feel like there's a lot of confusion about the new bootloaders. So let me try to clear some of it up.
You CAN flash 4.1.2 roms but NOT 4.1.x bootloaders.

If the zip contains any of those files DO NOT flash it.
If it contains just these:
(There may be other folders if the rom uses aroma)
it is OK to flash.

Do not PM me for help trying to get one of my mods to work.
