Fakeblank
It is not quite clear if fakeblank is a sort of bootloader (same level as 3.9 or 4.6, say a 'blank' bootloader) or if it is just a piece of code which is needed to run a serial payload at will and / or boots the normal bootloader (3.9 or 4.6) if no serial payload is run. The article itself is inconsistent regarding this point.

Besides there is a page Fakeblank and resorting / linking information would be a good idea, IMHO.

Change bootloader?
How does BootNeuter does change the bootloader? I suppose that BootNeuter use Gbootloader (see GeoHotz post : ) for changing the bootloader 4.6 stock/neutered. I suppose that BooNeuter use 112otb (see GeoHotz post : ) for changing a fakeblanked bootloader. But for the Bootloader 3.9, we don't know (maybe an upgrade to 4.6 first via bbupdater??) ?

BootNeuter does use geohot's extended secpack erase for erasing the 4.6 BL (as stated in its credits). For actually changing the "locked-down" NOR status of both the 3.9 and 4.6 bootloaders, BootNeuter uses the GPIO hack found by the dev team (and credited to the dev team by geohot within gbootloader/main-bleraser.c. Search that source code for the credit). The neuter patch is actually another matter, and is another (still uncredited and unmentioned (until now)) dev team discovery. And no, 3.9 is not upgraded to 4.6 before being neutered :) The 3.9 and 4.6 neuters are similar but distinct.-- MuscleNerd

Neuter Patch
MuscleNerd--can you elaborate on what exactly the "neuter patch" is?
