[Q] I Can't root my LG G3. Any ideas as to why not?

Basic Info: LG G3
T-Mobile Variant D851
Android Lollipop 5.0.1
Kernel Version: 3.4..0
Build Number: LRX21Y
Software Version: D85120e
Security Software: MDF v1.1 Release 2
I used to have my G3 rooted I was running the liquidsmooth rom on it. Then a few days ago I somehow managed to boot into fastboot mode and didn't know how to get out. I was able to get into twrp recovery but the phone would only boot into fastboot mode. Of course, I just decided to try something and cleared all the data from my phone and re flash liquidsmooth. It took me out of fastboot mode and put me into a bootloop.
I then used the LG Flash Tool to restore my phone to stock and it Worked! It sent my phone back to kitkat though so i updated my phone to Android Lollipop and tried to run avicohh's one-click root script again but it didn't work!
I then re-restored my phone to kitkat and tried again and it rooted just fine. :good: Then I updated my phone to Android L and of course, my root disappered. I tried to root again on 5.0.1 and the same thing happens.
( I attached an image of the command prompt). It says "Done" but I know it isn't. The prompt should be waaaay longer than that. When it worked on kitkat, there was more text there.
Tlr
My phone will not root on 5.0.1... Any ideas? I tried purpledrake and got the same issue.
I will provide more information if prompted to.
Thank You for any help you can provide.

How to root LG G3 D851 with MM 6.0
Why can't work on mine
How to root LG G3 D851 with MM 6.0 or install TWRP or Install Custom Rom like MIUI 8

hi,
you can downgrade your phone to D85130d by flashing a KDZ file
you can use the one from this topic :http://forum.xda-developers.com/tmo...ck-d851-30d-kdz-flashable-zips-imgs-t3367371;
then you can temporary-root it using Kingoroot , while on temp-root, flash TWRP using Flashify (available on Play store)
then flash SuperSu using TWRP and you're on full root.
this way worked for me.

marshmallow twrp and root help

just installed 6.0 on my lg g3 d855 32gb
trying to root and install a custom recovery but not able to. used the method with kingroot then installing supersu from twrp but then when booted supersu keeps asking to update binary and then freezes. am using the v30b-global-com version
any straight forward way to do it? without kingroot
i dunno if that's weird, but i can't even enter the fastboot to install the recovery using fastboot command

1) Fastboot doesnt work on LG G3 because it bootloader isnt natively unlocked
2) Please do not install TWRP on your current firmware. You will brick your phone
If you need TWRP you must downgrade to KitKat before you can install it.

I did install twrp and it booted normally. Using kingroot and a method i found on the forum. But the problem was with supersu that it kept asking to update binary which never happened. Anyways thanks for the reply. Phone not with me anymore

How to re-root a LG G Pad 8.3 (V500) already on Marshmallow 6.0.1

I rooted my LG G Pad 8.3 (V500) and I installed the AOSP 6.0.1 (MOB30J). It works fine, but for some reasons (?), I lost the root. Does someone know how to re-root the G Pad 8.3, already on Marshmallow 6.0.1 ? The root guides for Android 4.4 do not work and I do not find a guide for the 6.0 version. Thanks for your help.

Hi, you flash SuperSU 2.52 in recovery to root your Device? If still not have SuperSu after boot, you install it from playstore. It's will OK.

Hi. Many thanks for your answer. I have SuperSu, but it tells me that:
1- I have no binary installed
2- if I made an update to Android 5.0 (in my case, it's 6.0), I have to re-root my device manually.

As @hptnhan says, if you flash the latest SuperSU.zip from custom recovery then you should be set.

OK. I understand. I'll do it. Thanks for your help.

I have the same problem. Lost root after AOSP 6.0.1
I tried to flash the latest supersu zip 2.76 and got secure booting error and stuck on LG logo. Please help.

Restore to a 100% stock unrooted ROM using a KDZ or TOT made for your variant (V500). Flashing a TOT or flashing a KDZ with the CSE option will wipe everything including internal storage. If you flash the same version of the stock ROM that you were previously successfully running, you could try flashing a KDZ with the Normal option which won't wipe Data. If the tablet won't finish booting after that, try wiping Cache or a Factory Reset which will be the same as flashing the KDZ with the CSE option.

Thanks for your help. I was able to flash the stock rom. I installed ASOP 6.01 again and i lost root again. How do I gain root again on ASOP 6.01? Flashing the supersu.zip doesnt work for me. Is there another way to regain root on ASOP 6.01? Thank you.

I will ask the same question: How do i root my LG G Pad 8.3, running Android 6.0.1?
I've tried SuperSU 2.52, but got stuck on the secure boot error.

AOSP or CM 13? I haven't fooled with CM for any device in over a year but last I checked it includes it's own SuperUser app that you could enable. It might've been in the Developer Options section of Settings. You could also optionally try flashing an old version of SuperSU that's not Marshmallow-aware such as v2.46 or 2.5x (I think 2.5x was still not Marshmallow aware). Don't blame me for bricks though.
When I had tried CM 12.1 (for a different device, I don't have what you have) you could opt for flashing SuperSU.zip instead of enabling the built-in SuperUser app. I don't know if that's still an option under CM 13.

Sounds like you fellas are running wrong base ^^ (original firmware that V500 came with?)
Could be wrong as I've been out of the game a while o_0
Try a new base and then root, recovery and custom ROM it.

Cannot flash roms with TWRP

Hello,
I got a used G3 for my gf. I installed the latest LG marshmallow rom with LG flash tool.
After that I rooted and installed TWRP 3.0.2-0. Within TWRP I erased data and wiped everything.
Now when I try to install a rom (tried 3-4 different ones) I get this error:
"set_metadata_recursive some changes failed".
How should I proceed?
Great many thanks!

Just a quick question to understand what you've done:
If you installed "the" latest marshmallow rom with the flash tool, then how did you root and install TWRP? You can't root Marshmallow properly; That needs to be done from 10B.

Maybe I used the wrong terms. I flash "Europe D85530B_00_1217.kdz" with the flash tool. Afterwards the phone was on 6.0. Then rooted with Kingroot (if I remember correctly).

Trying to flash LG G3 D852 Virgin Mobile with TWRP

Hi, I can't seem to find a TWRP version specifically for the LG G3 Virgin Mobile model LG-D852 (FCC ID: ZNFD850). Which recovery image should I use? I've flashed the Bell TWRP image but when trying to boot to recovery I get an error. Phone boots normally otherwise.
Is this model somehow incompatible for some reason?
If so, is there another way to get LineageOS on the LG G3 Virgin Mobile D852 (perhaps through Download Mode)?
Is the hardware actually D852, or is it a D850 according to the FCC ID ZNFD850 and other markings on the phone which say "D850 0821", and under the battery which is etched "D850"? The mainboard also says "EAX65784001_1.0_D850_MAIN (2)"
(Edit) I have read that it is indeed a D852 even with the D850 markings, but still can't seem to boot to TWRP with the D852 IMG flashed (method is via adb su, dd if=/sdcard/twrp.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery)

maybe you haven't bumped the recovery
try this: https://forum.xda-developers.com/lg-g3/development/recovery-unofficial-multirom-twrp-artx-t3657524
I also use the d852 roger, and this worked fine

Thanks for the reply! I did go here: http://downloads.codefi.re/thecubed/lg_g3/bump/
I downloaded twrp-2.8.0.0_d852-signed.img, zeroed out the recovery and then flashed the image, and still get this error (Boot Verification Fail!!) when I try entering recovery:
https://imgur.com/a/MyIbx
I will try the image from your link
(edit) I tried the image from your link (TWRP_Artx-v1_d852.IMG), same issue, boot verification fail.
Do I also need to factory reset the phone after flashing TWRP to get recovery to boot properly? Does it matter at all that I'm using Marshmallow?

Using Marshmallow does matter since all TWRP for LG G3 can only be flashed to a Kitkat bootloader. You can use the AutoRec app to downgrade your bootloader to Kitkat, but the link for d852 marshmallow seems dead (here is the link: https://forum.xda-developers.com/lg-g3/general/apk-flash-twrp-autorec-thanks-to-t3081396). If you can find and install the app, then you can use it to install TWRP normally. Otherwise you have to downgrade to Kitkat to install TWRP. Strongly suggest you use the TWRP artx , it does not make the phone hot like the official, also have faster backup speed.

Thanks, I've been hunting for this file (wli.arecmm852 apk) for 5 hours now and still no luck, I will keep searching. It is probably my only hope, as a downgrade to lollipop seems unlikely, I can't find a kdz/tot that will flash with the Virgin Mobile D852.
I've tried flashing the bell D852 Lollipop recovery image to downgrade but it always fails. I have the right DLL installed and have tried the LG Flash Tool as well as the LG Update tool.
I am currently going to try to PM @Dene_Bluesman to try and see if they still have the AutoRec Marshmallow apk.

Solved!!
Autorec for MM D852 has been tracked down: https://mega.nz/#F!rtI1naZT!LJIKUVpv8fYjrvhpykA4_A!2o433RBZ
And works: https://imgur.com/a/s7KwB
Thanks, @Dene_Bluesman and @bender_007 and @Never_Sm1le !
I thought I was out of luck, but finally found it. I hope this will help others who are having trouble with their Virgin Mobile D852.
Steps I did to flash TWRP:
1. Installed KingRoot, which rooted my phone.
2. Installed AutoRec MM D852, ran it, and followed onscreen directions.
That's it! Now onto Lineage OS.
Thanks again all!
