I just upgraded my TWN 815 to MM using LG Bridge, and completely forgot that I would not be able to regain root access. Does anyone have a kdz that will enable me to roll back to Lollipop?
Alternatively, I still have the rooted system.img file that I used to root the phone (using the root injection method). Can I use that to revert to Lollipop?
I had to do with a new unrooted TWN 815, you have to revert to Lollipop - none of the rooting methods see the phone on MM. You can do it via LG UP - google for it (I think it was posted here), and find a 10x kdz file - that post has links.
If anyone knows better, I'd love to know. But it looks like you have to have the unlocked bootloader Europe version of G4 to have root MM. Planning to flog the phone and get one of those. Annoying. I wish the seller had made it clear it wasn't a Europe/Int phone.

Hi guys,
I've recently picked up a grey import G4 on ebay and opened it up, tried to unlock the bootloader and found out that it's a TWN model (Taiwan), so no unlock for me.
I'm wondering if, first of all, it can be downgraded from 6.0 MM to 5.1.1 LP and from there, injected with root?
I intend to eventually copy over various items via Titanium Backup, but require root first.
I've had a little look around but I'm not sure if this specifically is possible.
Help from seasoned veterans is appreciate.
EDIT:
title change, downgrade success, root success!
Found this thread: http://forum.xda-developers.com/g4/general/815-taiwan-v10f-t3298685 which provided the current/latest (to my knowledge) kdz and root system image.
Followed this thread: http://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803 to downgrade from MM to LP. (TIP: LGUP looks for .tot files, but feed it the .kdz anyway)
Followed this thread: http://forum.xda-developers.com/showpost.php?p=62028523&postcount=2 to then flash the rooted system image once downgraded.
Bonus:
Followed this thread: http://forum.xda-developers.com/g4/themes-apps/guide-installing-xposed-locked-t3181593 and installed Xposed too. (I'm using xposed-v80-sdk22-arm64.zip)
Currently running 5.1 LP just fine. Hopefully it stays stable. It's exactly what I'm looking for right now.
Cheers everyone who looked at this thread and the authors of these linked threads.
XDA is a pretty awesome place.
It seems downgrade and root is possible on most models. I would assume its on yours. Worked fine on my Canadian H812. I used LGUP to downgrade then used the original method to root, root injection may possibly work too.

To clarify: I say downgrade because apparently there's little hope for the moment of ROOT on MM.
Is there any extra risk downgrading stock LG MM to a pre-rooted image of LP?
I would assume I could flash the international/europe h815 version with root over mine -- H815 10D EUR or H815 10c EUR, assuming you can get a hold of either -- but wondering it this is the best or right choice. I don't want to end up with a broken phone, bootloop, or whatever seeing it is brand new.
I want to make sure what I would be doing is the best way to do so, and am willing to wait a little extra to make sure I do it correctly.
I've looked but haven't found a TWN rooted image, but it doesnt mean it doesnt exist.
Cheers, and thanks for the input
I got my G4 2 days ago and I really want to root it, but unfortunately I realised I have an H815P model and can't be bootloader unlocked, so I can't root it.
I looked around for ways to get past this little inconvenience and found there is a way to root without an unlocked bootloader. The problem now is, this method seems a little old and was originally created for Lollipop, but my phone shipped with Marshmallow already installed and on firmware version 20D.
So the question I want to ask is, will the method of extracting the system.img and injecting root and flashing that back, work with Marshmallow and my variant of the G4?
And if that is indeed possible and will work, will the root files from this post (http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765) work with Marshmallow, or is it specific to Lollipop?
EDIT: Another link to a tutorial about extracting the system.img and injecting root (http://forum.xda-developers.com/g4/general/tut-guide-step-step-guide-rooting-h818p-t3227798); will this tutorial and root files work with Marshmallow and my variant, or is it also Lollipop specific?
Something else I also want to add: my phone info in settings says it's an H815P model, but the Droid Info app on the play store reports it as a 'regular' H815. Does this make a difference, or is it just the app's inability to report the proper variant?
I'm really only interested in getting root, as I don't intend to flash custom ROMs; I just want to use one or two apps that require root, like Titanium Backup, and I'm sure there must be a way to get this device rooted.

You cannot root on marshmallow.. I downgraded my device to Lollipop using KDZ files and then injected root by flashing the rootedsystem image
If you have a H815P device you can't unlock the Bootloader so the only way to root it -for now -is on Lollipop. To get root access on your device you have to do this:
1. Downgrade to 10c (Android 5.1) w/ LGUP (http://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803)
2. Get root access on 10c (http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765) (don't listen to the warning not to use on H815P .. it works)
I have an H815P device and this worked for me yesterday..

This would mean then that I won't be able to upgrade to Marshmallow, or any other upgrades that comes after that?
U will be able to go back to stock. When u decide u don't want root anymore u can just flash the correct kdz for h815p and u back to stock
---------- Post added at 09:03 PM ---------- Previous post was at 08:53 PM ----------
Also you dont have to flash H815 kdz u can just extract your current system img and inject root with a ubuntu vm
check out this post http://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586
Both methods work well ive tried both on my device
You can always upgrade via LGUP but if you want to have root access so you must be on LP
Thank you everyone for your help and advice. I've downgraded and rooted now and it worked, with a slight side-effect; the downgrade formatted my internal storage and I lost all my pictures and other data
I wish the guides were a little more clear about this, that downgrading would format your internal storage, as well. At least I'm rooted now.
So, can anyone recommend an undelete program that actually works and can restore my lost pictures, specifically?
I have an Unlocked LG G3 VS985. I have been successful rooting it, but then I restart the phone and it does not stay rooted. It's running Android M 6.0
Software version: VS98547A
Someone please help me out.
http://rootmygalaxy.net/how-to-root-verizon-lg-g3-on-marshmallow-47a-firmware/
I flashed to 47A and lost root also (from 46A). I read perhaps going all the way back to 10b and then going to 47A from there may keep root. So I tried doing this today (link above) - but instead of flashing what the author recommended, i flashed another rom (aospa 6.0.1); i had root until flashing the rom, but couldn't find a way to keep it, again.
It may work if you flash the stock 47A rom the author provides. I'm not gonna try it again, though. I'll wait until there's stump root like apk that can do it for 47A.
I've got a Verizon G4 (VS986) software version 10b and I've been looking for the best way to root it and upgrade to Marshmallow (24c) while maintaining root.
I've tried looking through the forums and I haven't found anything that seems to match my scenario. I'd even be happy with root on a newer version of LL.
Root not available for Verizon G4 (VS986) on MM. If you care about root, 13B LL is your best bet.
Iv'e been using this phone for a couple of years now and he became very laggy recently so I though its time for a ROM, the problem is that as far as I knew back then there was no way to root the Israeli version (H815L), I mean sure its rootable but I couldn't find any guide, is there any really explained guide on how to root it? and if so which ROM do you recommend ?

International H815 10c Version (NOT H815T, H815TR, H815P, etc - you will lose internationalization and possibly features):

most people said it doesnt work in 815L
You will have to find a stock kdz android 5.1 for the H815L and downgrade if on 6.0. I believe the H815L has a locked bootloader so you will not be able to install a custom rom. You will however, be able to install TWRP-IN-FiSH a custom TWRP version for LG G4's with locked bootloaders (ask steadfasterX for help if the version is not listed) and Xposed to customize your stock rom, once you gain root.
Then follow the instructions in: Root ANY LG G4 Variant 100% Success Directives | Root Injection | Less Bricks : https://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t318058 (if you use a pre-rooted system image you can skip down to Step 3).
Use the command for the H815L under the Command to Flash System.img (All Variants) at [ROOT] TMO/VZW/ATT/SPRINT/INTL Root your LG G4 with Low Effort Root! Post #2 at: https://forum.xda-developers.com/showpost.php?p=62028523&postcount=2
I would recommend you do the root injection method yourself, rather than using a pre-rooted system image for any other model.
Try it yourself ... and see if it works. There should be no harm to your device if you've done it correctly, even if it doesn't work.
Addendum:
If you search the H815L (enter it right under the page number listings - in Search Thread) on the Root ANY LG G4 Variant 100% Success Directives | Root Injection | Less Bricks thread, you will see there are many instances where the root injection method has been successful on H815L's. You should be able to secure a link from one of the successful posters to the kdz they used.
