Just FYI, that info about the MD4 firmware is way out of date and actually potentially dangerous now that Knox is in play for some users; the failure was due to not modifying the asserts properly to reflect your actual bootloader. Britton, we definitely need to get some of these stickies cleaned up or updated, can you contact the mods. I am worried about the new crop of users who got a good deal for Black Friday/Cyber Monday and are promptly ruining their devices, or at least encountering complicated problems. Maybe a warning in the title about "outdated information" for those stickies not being maintained by the authors, I don't know, or remove them altogether and transfer the relevant, more current posts from within those threads to new threads.
The previous post is a little ironic to me because I just finished posting a thread on XDA designed to clear up a lot of the confusion involving bootloaders, modems, assert lines, and how Knox can come into play. A lot of their users are actually a step behind the VM/Boost users on this forum because we have been dealing with assert lines and bootloaders for a while, and the Sprint users, with their new MK3 bootloader, don't know what to do when they get an "assert failed" message due to the bootloader check.
