[G4 General] hyelton:
Here are all the current KDZ & TOT files for flashing Your G4 Back to Stock! This Guide includes 3 different methods. KDZ, TOT, and LGUP (Which flashes both KDZ & TOT files)

Will Be adding Firmwares as I get them, This guide applies to general ALL LG models including G2 and G Pro, G Flex, G3, G4,G5, Etc. .

NOTICE! - IF you download fails or does not download all the way USE A DOWNLOAD MANAGER!, Files that are usually over 1GB browsers have issues downloading them especially if you have a slow connection.

First Off Not Responsible if you flash the wrong one!!!!

Please read HERE if you plan on downgrading, WARNING downgrading some models will result in a perm brick! Mostly AT&T, T-Mobile, and Sprint models.
