root (stump) , re-root (IOROOT), BUMP, TRWP,
Rooted with STUMP initially just fine. Then had to factory reset due to a malfunctioning app.
Stump does not (yet) support re-root after reset unless you flash back to stock. http://forum.xda-developers.com/lg-g3/orig-development/root-stump-root-lg-g3-sprint-verizon-t2850906
Thanks for all the helpful posts in several threads. I Rooted using IOROOT, using ADB no problem. http://forum.xda-developers.com/showthread.php?t=2776198
Now running BUMP TRWP recovery too. http://forum.xda-developers.com/ver...pment/bump-unlock-lg-g3-twrp-verizon-t2900590
BUT, since i'm somewhat of a n00b, i used Flashify from the Google Play store to flash the image. Worked flawlessly. http://www.droidforums.net/threads/...ock-and-install-recovery-on-any-lg-g3.275056/
(in flashify, pick 'choose file' and navigate to the .IMG file)
Thanks!!

My phone does NOT work so I'm not sure why the change log states 12B.
What was upgraded, fixed, etc from 10B to 12B? Not really a fan of downgrading.

[Q] Help need [TWRP]

Earlier today I rooted my LG G3 [VS985] But prior to the root, since verizon has yet to give us the lollipop update, I figured I would update early, I followed jhnom96's guide on youtube ; I rooted with Zedomax's tutorial for lollipop ; After many failed attempts to install TWRP bump for the lg g3 vs985 with flashify and es explorer, I followed all the directions from this guide: a guide by zedomax on how to flash twrp; in which when the device was restarting , I was prompted with this message in the corner of the screen: secure booting error cause boot certification verify lg g3 ; I'm pretty sure it had something to do with me updating to android 5.0.1 early on verizon, but I was wondering there was a solution.
Thanks!
(Sorry, i would post the youtube links but the site won't let me since this is within my first 10 posts, so you'll sadly have to look up each video specifically.)

TWRP hasnt been updated to support Lollipop yet

Well if someone can find a solution somehow, that'd be great.

Invalid Software Package & Rooting questions

Hello XDA,
I got an LG G4 gifted, and as one of the first things I want to do is to root it. However I seem to have quite some difficulties with it.
My previous phone was a Nexus 4, and I simply rooted with 'Nexus Root Toolkit'.
For this phone there appears to be many, different ways to do that.
First thing I need to be sure is what exact model my G4 is.
In 'Phone Info > Hardware' it simply says H815. In the LG Mobile Support Tool it says H815B (Which gives no result on Google). The phone is from Germany if it helps.
Second thing is that it says I can update to SW version v10c. But when I download the update, it simply throws a 'Invalid Software Package' error at the end of it. The LG Mobile Support Tool says I have no update avalaible instead.
Third thing is that I don't remember if I have to unlock the bootloader to root my phone (did that only once on my N4, forgot if it's needed). If yes, can somebody link me to the appropriate page? (I've read around LG itself released a tool to unlock that?) (Also, I will loose all my data IIRC?)
Last thing, obviously, the most appropriate Root guide for my model. I've read many of them, one requires you to have linux on your PC (Which is a nope), others mentions '10c' (which I suppose is the update I'm unable to get). So far I got myself only very confused. (Root voids warranty? IIRC LG still covers phone with root?)
Thanks in advanced for your help
EDIT: Currently trying with LG Bridge software, seems to work and says my phone is H81520A (So I suppose the part after the device code is the 'SW Version' ?).
EDIT2: Apparently updating with that software worked. Now on v10c (Marshmallow 6.0 - Unless there are other updates waiting)

You can indentify your model by adding your IMEI to the following link: csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=
(look for the field buyer)
The unlock process is described in this thread.
But don't fash SuperSu If you are on Android 6.0, because it will fail to boot. First flash an custom kernel (like this) and then SuperSu.
If you're unable to unlock the bootloader, then there is no possibilty to get root on Android 6.0.

Thanks. It says DEU at the buyer line.
D(eutschland)EU(Europe) I suppose.
And thanks for the link. In the kernel page it says 'download 20a or 20b? What's that number? So I need a Kernel that inclused SuperSU as flashing it on its own will cause that problem in few words?
What about this? http://forum.xda-developers.com/g4/development/repack-kernel-root-android-6-0-t3232387
From what it seems, it's a custom kernel + root. Would I still need to unlock the bootloader? Perhaps using the 'LG Site' section from the thread you linked (http://forum.xda-developers.com/g4/general/unlock-bootloader-install-twrp-root-t3128241)?

The software versions are quite strange on lg phones. 20A was the first test version that was released in poland. The official version now is 20B but phones with a branding have different versions. For example my phone has a vodafone branding and has the version 20A, but it is the same as unbranded 20B. (so it's really strange some times)
Look what is written in the settings under software information.
You need to unlock your bootloader to root your phone on Android 6.0 (this will void your warranty). You're right, it seems that SuperSu is already integrated in the kernel so you don't have flash SuperSu separately. But i am not complete sure because i didn't unlock my bootloader.

Thanks a lot for your help.
I managed to unlock the bootloader, but then I fuffed up..
Accidentally installed SuperSU (Was following that guide, and forgot about what you said).
Now the phone is kinda stuck at the very start, with the LG Logo (Not the animated one, the very first one)...
I'm hopeless now? D:
EDIT
I'm trying to recover with this video (LG G4 KDZ Firmware Restore Unbrick and unroot tutorial -- can't post links yet..)
But the LGFlashTool throws an error at 9% (imgur link -- can't post them fully yet) imgurDOTcom/pR1NYHD
EDIT2
Apparently I'm trying to flash a KDZ with Android 5.x while I'm on 6.0, which is a no. Will try with a 6.0 KDZ if I find one...
Else I hope for LG assistance (Or Amazon support, since the phone is less than 1 week old)
EDIT3
No luck with KDZ, but now the phone is going past to the animated logo, but being stuck there..
EDIT4
This saved me: http://forum.xda-developers.com/showpost.php?p=63843511&postcount=146
Worked perfectly, my phone is back and fully working

Sorry, i wasn't online the last couple of hours, but i'm glad that all worked out for you

No problem, you were of great help.
I'm currently not trying to root until there is a safe procedure to do so for 6.0

I don't think that there will be an easier option in the near future. You can make a backup with twrp and try to flash the kernel again.

Mmm, currently I have only the bootloader unlocked. No root, no custom recovery.
I don't feel like to play more with these stuff in the near future, after I nearly bricked the G4
Perhaps later on.

Accidentally Flashed Rom for D855 on to model D852

Hey Community!
I am recently playing around with my Canadian Fido lg g3 phone and was planning to install lineage OS on it. I was strictly following these instructions: https://forum.xda-developers.com/lg-g3/general/guide-how-to-install-lineag-os-t3558777 . Everything is fine until step 6. Lineage OS is not booting up and it is constantly restarts the phone. I then noticed that the model number on the back of my phone is LG-D852, so I believe I am flashing the wrong ROM.
I tried to revert back to the stock ROM but failed, I followed https://forum.xda-developers.com/showthread.php?t=2785089 as well this https://forum.xda-developers.com/lg-g3/help/solution-flashed-wrong-model-rom-to-d852-t2987242.
I tried flashing the generic dll file using LG FlashTool but that did not help, I am getting an error http://imgur.com/a/CQ5R2
Can you guys please help me out.

LG G3 D855 root problem

Hello!
I've got a little or maybe a big problem with rooting my LG G3. For now i've got android 6.0 Marshallow installed.
I spent on this whole day and I think i tried every possible way.
I tried stump root(i guess it only works for kitkat) , purpledrake root, kingroot..
Moreover I tried to downgrade to android 5.0 but my device is "unknown" for LG UP. Also, I tried LG Lash tool but it returned an error too.
Do you guys know any other way to root this device? Thanks in advance ;c

I got the same problem.

Hi! Sorry that I'm responding so late. I found that i had the problem with downgrading becouse of wrong LGUP zip.
I found correct one here https://www.youtube.com/watch?v=81kb6fqHxUo&list=LLF_c9VT9RRrxMaH_s9qwFWQ&index=1&t=283s in video description.
Now with LP installed root should be possible.
