[AT&T Samsung Galaxy S 4 General] rebel1699:
Since 4.4.2 NB1 was released, those with locked bootloaders have been stuck with either upgrading to NB1 and losing root and Safestrap,or remaining on 4.3 MK2 and missing out on the upgrade fun. Well, this is a solution for both instances. I was made aware of a process the Note 3 was using to upgrade to 4.4.2 rooted roms with the existing version of Safestrap. After some study and alot of building, testing and modification, it is all ready.

It is called Deadly Venom KitKat Magic Tool

Version 1 is for those that already took the NB1 update.

First, follow the thread here http://xdaforums.com/showthread.php?t=2663545 to revert your system back to MK2. You can then root, and install Safestrap. Be sure to hit thanks on [MENTION=2284570]ted77usa[/MENTION] post.

After flashing the MLD or NB1 modules, it will say there is no system installed when trying to reboot from safestrap. Dont worry about it, it will boot fine.
