    Is there a guide, or a known method for upgrading the firmware on a SGH-M919 while rooted?

    Currently if you upgrade to 4.3 you will lock your bootloader. I would recommend you wait I will post a link later tonight hoe to update without picking up knox!

    The two ROMs I've tried that update to 4.3 have caused my mobile network to intermittently turn off and on. Switching back to 4.2.2 made the problem go away.

    There is something fishy about 4.3, or it just doesn't like the S4
