Only an hour ago, the LG G4 Marshmallow firmware (20A) leaked straight from the LG servers, and we now already have a recovery flashable zip of the firmware that’s 100% stock. Huge thanks to autoprime.

The new LG G4 Marshmallow firmware 20A has newer modem, boot, bootloader, etc, as you’d expect from a major Android update.

Below are download links for the stock system, modem, boot and bootloader zip files that you can flash via twrp recovery to install the Marshmallow update on your G4.
