Stock LG G4 Android 6.0 Marshmallow firmware now available for flashing

by: Edgar CervantesOctober 25, 2015


LG has begun rolling out the Android 6.0 Marshmallow update for the G4, so it was only a matter of time before developers got working on some sweet ROMs. Maybe you are not looking for anything fancy, though. Hell, many of you are not getting the update in a while and simply want it right away!

We have good news for you today. XDA Developers autoprime has just published the stock Android 6.0 Marshmallow firmware, and you can flash it right away. A=But as it goes with these topics, there are certain things you must keep in mind before you go trigger happy.

Android 6 Marshmallow raining crop

For starters, this firmware is only for the LG G4 H815, which happens to be the international version of the smartphone. Flashing the software is also not as easy as it is with your average updates. Users must have TWRP 2.8.7+ installed, which in turn requires you to have your bootloader unlocked. The developer mentions one should also have unlocked the bootloader via LG’s official unlock tool.

Do you meet all the requirements? The let’s go through what you need in order to get it all done. Before anything, though, we would like to remind you that tinkering with your phone may harm your device and/or void your warranty. Make sure you know what you are doing before proceeding, and do your research. No one but you will be responsible shall anything happen.



When coming from Lollipop… you will need to at least flash the system and boot zips. Modem and Bootloader zip may be optional. I’d suggest flashing all 4 zips. Bootloader first.. then order after that does not matter. Do NOT wipe system partition until after you have flashed bootloader.


Wrapping up

So there you have it, guys. No need for waiting, though I would advise that you stay put if you are not used to playing around with software like this. If you are an Android adventurer and choose to go through this, do let us know your experiences in the comments!

    Now would be the time to look for some deals on G4.

    • DBS

      Well, I just got one, new and sealed, for 390€ on eBay ;)

      You can already pick one up brand-new on Amazon for less than the price of a Nexus 5X. It has several advantages over the Nexus, my favourite being the expandable memory

      • SpvceCats

        Link? All I see are $450+ :(

        • TheNash

          I should have been more specific I guess… I’m in the UK and here it’s currently selling for £319. The 32GB Nexus 5X is £350

          No idea about other regions, but I had assumed it might be similar

            Nah the nexus and a bunch of other phones are usually a lot more expensive in Europe, he can pick up a nexus 5x for a lot less

  • Mark van Woerden

    Have someone already done this? If so, could you send a link for a review? Would love to see that!

  • Dudesrus

    Then find out its buggy as hell and have to then reflash the original rom that it came with and have a nightmare tracking down the rom, thanks but no I have had this many a time before and prefer to wait until it has been around a while before fxxxxxg up my phone

  • TT

    Just for clarification, its only the H815 Europe (H815EUR) verison that has the official unlockable bootloader from LG.

    I think custom ROMs may become obsolete since you can’t use things like android pay with it.
    But they may find a work around, and paying with your phone isn’t going to become the norm in quite a while, probably when the physical wallet becomes obsolete which is a long way away.

      For me, custom ROM were good at doing job for unsupported flagship. i.e Samsung Galaxy SIII, Note 2, etc.

    I wonder if this stock Android 6 compatible with LG G4 model#812?
