The owners of LG G4 can rejoice, for those who don’t know, upgrading to Marshmallow broke the ability to rollback, and those unfortunate users who did that got stuck in a bootloop and flashing the older KDZ didn’t work simply because the flashtool needed to be update. Well, today’s your lucky day, there is a new flashing tool for LG G4 called LGUP. Using this tool you can upgrade to Marshmallow without fearing the impossible rolling back that was plaguing several LG G4s.

Using the LGUP is as easy as it can get, all you need is the KDZ file for your LG G4, a USB cable, and some basic Android knowledge. However, if you are still willing to get some help regarding this matter, you can checkout our handy guide below.
