Can i root my lg g4 with this version? And how?

Sure. Perfectly. At least two different ways. If you do not need and care about device encryption just search for the low effort root in this LG G4 Forum original Android Development. Search for a flashable 10C rom.
If you need device encryption, go to LG unlock your bootloader officialy, flash TWRP and flash su.
Thread for this is right here in General G4. Called complete Guide to unlock & Flash H815 or similar.

Hi, unfortunately this happened to me (more than once) when I tried rooting the first time. You'll need to download the stock image files and the LG Flash Tool to start over from scratch. I'd link you but I don't have enough posts yet to be able to.
The trick is to make sure the rooted image file is over 4 gigs when extracted, I ran into issues multiple times where the download got corrupted along the way and ended up being a few hundred meg. Keep trying and once you get the right files the Low Effort Root is amazing.
Good luck and if you need any more help please let me know!

Android Marshmallow G4 Root

When android Marshmallow releases will we still be able to root our devices with the low effort root available now?

I'll be the serious guy...
Theoretically (meaning I take no responsibility for what might/might not happen, and of course have not seen confirmation of this working except over Lollipop)...yes you could root with the low effort root if you're on M.
All you're doing is flashing a rooted Lollipop image over the stock one, so yeah you'd be going back to Lollipop but yeah you'd also be rooted. It's a downgrade but I suppose it would do for the time being if you really wanted root and for some reason took the M upgrade without wanting to.

I don't think the Lollipop image would work. Root would need to be injected into a M image.
Sent from my VS986 using Tapatalk

The reason he was being sarcastic is because there is no way to know if we can root M until it actually comes out. It's like asking if the LG G5 will be rootable, no way to know until it's out.

I tend to agree, I was just saying in theory it would work...
People used to downgrade from LP to KK with pre-rooted images.
But yeah the 100% surefire answer at this point is who freakin knows. I'm sure a root will come along eventually, just gotta give the developers some time.

In all seriousness it most likely will not work. Android M will almost certainly come with upgraded boot.img, etc and most new phones with locked bootloaders are preventing downgrading and/or preventing of unsigned images so its quite likely we will not be able to downgrade. This is my first locked LG device so I could be wrong about the G4.
Sent from my VS986 using Tapatalk

Yea no one really knows. Lollipop really made rooting complicated. Phones like the G2 and G3 were able to use older partition firmwares that were still rootable but required KitKat parts. With the G4 having stock lollipop, it was more complicated.
I suspect that we will always be able to root similarly how we did already. The USB>COM>flash a custom rooted system image should still be an option. This method is how the LG updater tool works. If they block access to that, then everything will break.
I have faith that we will be ok but like everyone said above, we won't know until it is released.

If that bootloader is unlocked and the good ol' legendary Chain man has a nice, sweet, hot binary in SuperSU to shove up that there thang. Then, I don't see why not. You can root through TWRP or whatever custom recovery you choose to use to overwrite the partition when you're boot scootin' boogied.

Google is really trying to lock their OS down. They make it harder to root, and now Android Pay won't work on rooted phones and they have an API for developers now to restrict or prevent use if the OS is modified.

This is a stupid question that's why it was answered sarcatically. Its a new version, so when root is out it would be posted or if someone tries the old root and it worked they would post it. Otherwise you would ask if anyone is working on the root. You basically asked if a new phone coming out if it will be rootable.
Also why are people asking tmobile questions in a verizon thread.

No root possible on verizon MM. They plugged the hole so we are no longer able to pull and push the rooted system images like we were.
The V10 is facing a similar issue and they've been at it longer. So until then, I just disabled the System Update app in settings.

H815 TWN, differences from EU?

I am certain my G4 is TWN, from the box and the software version. But what are the actual differences to the European H815? Specifically, can I flash European KDZs or use the EU command for flashing a rooted /system image?
Code:
dd if=/data/media/0/system.rooted.H81510c-EU.img bs=8192 seek=55296 count=529920 of=/dev/block/mmcblk0
Thanks

I have a the TWN version too damn it. - that's what happens when you buy from a global vendor over the internet .
Good news is that you can flash the EU rooted system image. I did and it worked fine.
Bad news is that you can't unlock the boot loader (yet), which means no TWRP or custom roms and flashing a stock Marshmallow leaves you without root and no way to downgrade.
Cheers
BTW I don't know of any differences between the EU and TWN devices other than the version coding - to me it just seems to be a way for LG to control their different markets.

Thank you for this. I do not want to unlock it just yet, since I bought it from a local vendor and I have a 2 year warranty with them. I see there is already a rooted image for v10d TWN, so I will flash that soon (are you sure the parameters for the dd command are the same?).
Sidenote, it would be nice if we could compile our own KDZs and make rooted ones.

I can't really comment on the all the parameters in that command string except to say that it's one I used and it worked well. Whether those numbers would need to be modified for the 10D image or not I can't say - I would suggest you ask the author of that original rooting thread.
BTW you can't unlock the bootloader on the TWN version just now in any case. I tried the official method over the weekend and was told the TWN version was not supported. There's unofficial unlock method available for any G4 variant yet either but people are working on it.

Probably the parameters aren't different between firmware images, because they depend on the partition table of the device.
Now waiting for a version of Xposed that is confirmed not to drain battery. Thanks again!

I'm running xposed now with about 10 modules. I don't see any great battery drain.

I did the same thing, buying online and getting stuck with TWN. I came from a GS6 and was thinking "I'll wack an AOSP ROM on the G4 and I'll have the perfect phone". Now I'll probably never buy another LG even though I actually like the G4 but when we pay close to $1k for a phone we should be able to do what we like with it!

There is a thread for stock marshmallow which you can install with flash fire but there's no root available with that option just now.

The thread I'm talking about is http://forum.xda-developers.com/g4/development/stock-h815-20a-stock-rom-t3233049
BUT be warned you will lose root !!. So far as I know just now there is no way to get root on stock MM without an unlocked bootloader. This may have changed inthe last couple of days - you'll need to read around the forum.
ALSO there is no sure way back to L is you decide you can't live without root (I certainly couldn't so I'm waiting for further developments). I think I read that someone here more-or-less accidentally managed to recover back to L but I didn't really have time to take in all the details so futher reading needed if you want to take the risk.

VS996 (Verizon V30) 10C Full KDZ Download (AFH) + NEW DLL File

Hello Verizon V30 Users,
I am providing the full KDZ file for the Verizon V30 software version 10C, the latest available for the VS996.
You can download it from HERE!
Coming from the V10, I've noticed the KDZ for the Verizon V30 is almost 3.5 GB, compared to just over 2 GB with the V10.
>> NEW DLL FILE REQUIRED TO FLASH!! <<
You must use LGUP to flash this. If you haven't upgraded your DLL file for LGUP, inside this same archive, you'll find a dll file named LGUP_Common.dll. Place that DLL file in C:\Program Files (x86)\LG Electronics\LGUP\model\common. Just as a precaution, change the extension of the existing LGUP_Common.dll to .bak or something in case this doesn't work for you. After you put the new DLL file in that folder, open LGUP and in the very lower left hand corner of the window, you should see DLL Version 1.0.31.9.
Enjoy! If anyone has any questions, feel free to hit me up!

Reserved

And again.

Perfect! I was thinking about buying the V30 but was worried I couldn't dev on it as there was nothing to go back to. Thank You.

There are rumors someone cracked the bootloader and rooted a Verizon LG G6, but for their own reason chose not to publish the method. Knowing the person who told me, I have no reason to doubt it. But, no, I don't know how they did it, as I am not a dev.
This of course leads to a bunch of questions. Is it possible some of the 2017 LG flagship (G6, V30) carrier models have ADB flash commands if you can get past the bootloader? We know the T-mobile LG G6 and LG V30 do not, because the bootloader is easily unlocked and they are ADB crippled. We just assumed all the other carrier modes were the same way, because no one has cracked the bootloader and published the results.
Or this person cracked the bootloader and found some other way to root. They didn't go any further than that, but they did unlock the bootloader and root a Verizon LG G6.

That link above discusses it more, but other than that I'm not interested in "proving" anything. I'm not the dev, and he can release what he wants to release. I encourage everyone to buy the "open market" version of the LG V30. That will have guaranteed root, TWRP, ROMs, kernels, etc.
If you want to read where I got it from, read back through my posts. It was discussed in open thread about three weeks ago.
The only reason I'm mentioning it here is it might be relevant to the LG V30, to let people know a carrier branded LG G6 was bootloader unlocked and rooted. If one person can do it, others can.

Dirty Santa exploit cracked the bootloader of the V20 (December 2016). And here (June 2017).
DirtySanta Exploit Unlocks the Bootloader of the LG V20 H990 -- XDA article, June 2017
And the 2016 V20 still had all the ADB flash commands. So, once past the bootloader, you had free reign. That has changed with the 2017 LG flagships, where LG has removed most of the ADB flash commands.
Even this LG V20 method, in a thread started END of August 2017 has as a first step -- RUN Dirty Santa! Even though Dirty Santa/Dirty Cow exploit was now patched, you can swap out modules in the phone, so it will then still run. So, I do not know of any LG V20 that were rooted where the bootloader was not first unlocked -- even if you are replacing out modules with "Engineering" modules or whatever to allow Dirty Santa to still run. If you have other information to the contrary, I would be interested in hearing it.
Now back during the LG G2 and LG G3 era you could root and install TWRP without unlocking the bootloader, but that was back when signed packages were not required.

I'm not a developer, but I research a lot and I have knowledgeable people tell me stuff.
I keep up with LG phones, and I know V20 bootloader was unlocked by Dirty Santa exploit. Which was why I corrected the misinformation that the V20 was rooted without unlocking the bootloader.
Maybe there's another method of rooting V20 of which I'm unaware, but in V20 forum all I see are the links I posted above - which all involve unlocking the bootloader.

But the v30 is too new to have a dirty santa version anyway. And no adb commands.
Unless this makes it on to the lg list for unlocking I dont think it will happen.

Nope, any Samsung phone that's sold in the US aka having the letter U or DL "not too sure about ones with U1" cannot be rooted due to having a locked down bootloader and no OEM unlock option, it's been like this ever since the S6 back in 2015. an exploit for the SM-A236U and the SM-S236DL would need to be found to even get close to rooting.

this method works. BUT......
i can root my phone. magisk works fine, but apparently I don't have write permissions on /system
it is unusable because android is annoying me with "service provider update.... the phone needs to be restarted." you can't click away either. over and over again.
SM-A236B

So i unlocked the bootloader and flashed with odin magisk patched boot.img and everything is working fine. Except SELinux, which is in permissive mode now. Jeez.
