LG is finally rolling out the much awaited Android 6.0 Marshmallow update to the T-Mobile G4 with firmware build number 20i.

The update is already on the roll as we speak via OTA, but if you’re rooted and can’t install the OTA update. Then you can download the full KDZ firmware for the T-Mobile G4 20i Marshmallow update, OR, if you don’t wish to mess with a KDZ, then user autoprime over at xda has also posted recovery flashable fully stock ROM zip for the 20i firmware. You can use either of the methods to update your G4 to Marshmallow.
