An update – D85520F – has been released for the LG G3 (855) a few days ago.
This assumes that you already have a rooted ROM either 4.x or 5.x as well as have a custom recovery installed.
Proceed at your own risk – I am not responsible for anything that may happen!
- If you are on stock (4.4.2) and not rooted then you can follow my guide on how to achieve a rooted Android (Lollipop) 5.0.
- If you are coming from a different ROM then you need to do a full wipe (data, system, cache) before continuing
- If you are running a rooted 85520D version from my previous guide then you can continue
Download the 85520F.zip and latest version of SuperSU from the links above and place them on your internal storage.
Reboot in recovery either via ADB or Quick Boot (mentioned above) and perform a full nandroid backup.
Install the 85520F.zip from the location you copied it earlier in local storage and don’t reboot just yet!
Install SuperSU from the location you copied it earlier in local storage and don’t reboot just yet!
Wipe cache and dalvik cache and reboot.
First boot will take a little longer but you should eventually see the applications upgrading notice.
