Lg g3 d851 running Marshmallow 6.0 Error flashing lollipop :/

I am Using 6.0 but It's draining battery too fast and I would like to downgrade to lollipop But when i flash it using the LG FLASH TOOL 2014 using kdz file then on download mode it just blink the screen of download mode and tool says RETRY
I have setup everything like driver etc everything is good and setup
I think it some thing like that 6.0 blocking to downgrade, I can't understand why this happening
And I have installed LGUP too is says "Please connect the known device" :/
Help

Had the same problem. You need to download the required DLL for LGUP to find the phone. Just google: LGUP d851 DLL and look for LGUP_8974_DLL_Ver_0_5.MSI
Once you install the DLL LGUP will work and you will be able to flash lollipot

Thanks a lot Brother :good::good::good:
It worked for me

[SOLVED] Boot loop after trying to root!

So I followed the instructions EXACTLY as said.
All went well until I had to boot into TWRP, from there I was bootlooping and getting the "Boot Verification Error...MISMATCH_SIG_LEN"
I followed another set of instructions to follow the same steps but instead flash the stock tot.
So I did that, but about 5 seconds after pressing "start" I get some antirollback error (posted image below)
Ive tried flasing via the upgrade option, as well as the refurbish option
Ive done a ton of searching and I found noooo solution
Please help :crying: :crying:
[UPDATE]
Alright guys, so I started getting frustrated and adventurous lol, and after a good amount of digging I found a solution.
So the antirollback is basically just a feature preventing downgrades from what Ive gathered, meaning you cant flash the stock TOT file that a couple people suggested (THIS IS IF YOU'RE ON 10D BTW AND TRIED TO USE THE ROOT METHOD) because its a 10a software.
So I decided to search for a 10d stock tot file (with no avail) BUT i came across a 10d stock kdz file, which absolutely got the job done.
So just download the kdz file and flash it using lgup
Link to the the kdz file: here
I tried to make this as thorough as possible for noobs like me lol

Problem after flashing firmware and skipping Supersu

So recently I wanted to flash 20a via twrp on my G5 but it wasn't working. I reflashed 10i and my phone didn't want to boot up. So I decided to charge my phone after reflashing 10i once again without flashing supersu and I powered off the device and it turned back on with the "Your device is corrupt and it cannot be trusted sign" and so I tried to boot to recovery and my phone just factory reseted itself. I tried to boot into recovery with adb but to no avail. I even tried to flash 10d kdz and 10d tot both getting an error on LGUP and my phone is still stuck on firmware 10i. I even get an error when trying to update it with stock recovery. So now I have a phone with an unlocked boot loader and I cannot reroot again. Is there a way I can regain root? I knew I should have flashed supersu

I bet you didn't followed or read the 20a thread by autoprime nor did you bothered to read the TWRP thread as well. there's still a bug that prohibits you to downgrade from 20a unless you have a nandroid backup or a twrp recovery backup for the 10i. best option for now is to go back to 20a and wait for an update from the devs on fixing TWRP or try to follow the dirtycow method.

Look under the dev thread on autoprime topic about the stock N zips, if you read through last few pages you'll find all the links you need for recowvery to get root and twrp. Also if you're on 10i, why not just use lg up (make sure you either use older version or autoprime uppercut app) to flash 10D tot that already has twrp and then upgrade to stock 7 through twrp. Either way, all the info you need should be in last 3 pages of that thread by autoprime.
*** Edit ***
Just reread your post. If your getting errors flashing the 10D tot it's most likely due to you updating lg up, the .DLL, etc to install N. If so, uninstall lg up, and then download the lg up files and. DLL from the 10D thread. You can try uppercut app too as it's supposed to work between versions but I have not tested it myself. If all else fails then use the recowvery method.

I've tried uppercut and I still get errors. I want to downgrade using the kdz file but the link is broken for me. Though I will try an older version of lgup. Thanks :good:

Yeah not sure about uppercut. If you're still on 10i you should be fine using lgup to downgrade as long as you use the right version of lgup and h830 .DLL file. Also I'm not sure you can use refurbish option with kdz, but I know you can with tot. So maybe downgrade to 10D using tot and upgrade through twrp. If all else fails, use the recowvery steps on the above linked thread and you should be all good. Quick question, when you first start your phone, does it just show phone can not be checked for corruption or does it show the message can't be checked for corruption and visit this site... Etc. ? Reason I ask is the second message is updated bootloader and you won't be able to use lg up to flash MM firmware until you downgrade your bootloader.

Updated bootloader? I had no idea that was a problem. But since I'm on 20a i get the corruption message plus the link so O guess my bootloader is upgraded. How exactly DO you downgrade the bootloader?
I will mention that I'm stuck without twrp

Okay since you have an upgraded bootloader and no twrp you will have to follow the steps in that post for recowvery which will give you Root and twrp. Once you have twrp, download the bootloader zip for whichever version you're planning on downgrading to (I.e. 10I bootloader if flashing 10i kdz) from autoprime and flash in twrp. You can also flash the complete zip (i.e. 10I complete zip) in twrp after flashing the 10I bootloader if you want to keep root and twrp (you will also have to flash SuperSU after flashing those files). But you can also flash kdz or tot with lg up after downgrading bootloader via twrp but you will lose root and twrp unless you flash 10D rooted tot.

I don't think so but not 100% sure. If you follow the steps carefully you'll be fine. I didn't directly post the recowvery steps as I have not used this (I've had twrp and root since 10D). You can look on the v20 thread as it has a post for the v20 and our h830 recowvery method. Sorry I can't be more help with that specifically.

T-Mobile LGV20 H91810j KDZ

have at it folks... grabbed from LG Bridge and updated from it as well... https://drive.google.com/open?id=0B6Wj13Rw1kw-QTViRFJRaVRHQnM

Was just about to post this haha so here is a mirror if anyone needs it.
https://mega.nz/#!9cRnCCzQ!3Z8bDQnwr6_3wa3kUjMfU005mjdHh8Jq0EgtgYQMflo (includes the dll file as well.)

Can I upgrade from rooted 10d with this? Or do I have to update to 10i first, then 10j? Also what settings to choose in LG bridge?

If your using the image posted you can use LGUP, if your using LG Bridge it will download the image for you.
You need to be on a stock ROM I believe, I flashed the stock odexed rom. You can try it on a custom ROM though and see what happens.
If you want to use LGUP then you can download the above images.

What about stock recovery? Is that needed? If so how do I flash that?

It just overwrote trwp when I updated.

my upgrade steps were as follows:
backup anything you might need from the internal memory - /sdcard
backup anything you might need with TiBackup (just in case)
boot into TWRP and make a backup of /data
update to 10j via LG Bridge or LGUP (you will be returned to stock after this)
boot up and follow @jcadduono's post on rooting H91810d with recowvery
his detailed guide will leave you in TWRP with a freshly formatted and unencrypted /data
restore backup of /data in TWRP
done. profit.
NOTE: crucial you backup your /data in TWRP prior to updating because after updating your /data partition will be encrypted and you will no longer have root. once your /data partition is encrypted TWRP won't be able to see it. I believe you can still root with an encrypted /data where you'll then be able to use TiBackup to backup your data, but this method would be a slow restore versus restoring via TWRP.

Here's another mirror for those interested. All three files are in a ZIP since Android File Host doesn't play well with uploading KDZ files.

Can anyone extract the ing files and make them flashable so we can update through twrp? My hard drive went out last week so I can't update and keep root without doing it through twrp.

You just need to build the file tree and make a script to tell them where to go, I believe.
Or we could at the least flash a 10j based rom and then install the system img over it. Just need the extracted imgs from the kdz that way.

Um so after updating no more TWRP and still can root bit confused here?

updating and rebooting will revert you back to stock... you'll need to redo the steps for recowvery to install TWRP and root again... you'll also need to backup your device as you'll need to wipe /data to unencrypt

Can I just take the OTA to 10j and wont cause any bootloops? then just re-root?

Is this 10j rootable as 10i? Someone did it?

Has anyone got H91810j rooted? Yes? Link me to a source with walkthrough.
SW: H91810j
build: NRD90M
Kernel; 3.18.31
amdroid securitu patch 12.1.16
security software version MDF v.20 rls 4

Yes its possible to root the 10J patch. You need to do the commands manually.

I've ran the commands manually and I get confused about the .xml copy being put into local_manifests. I made the directory in my C: drive but Its a windows not linux computer I have access to. Does that matter?
So I get to the manual inputting part, right... And prompt says can not find file
at the first manual input of dirty cows command prompt

Just wanted to thank you, because you're a lifesaver. I bricked my phone (unfixable TWRP loop), and I tried downloading the KDZ several times from LG-firmwares, but it was extremely slow and always ended up failing. Then I found your Drive link, and approximately 9 hours after bricking the damn thing, I was finally able to fix it. Learned my lesson, too. I'll never again mess around with a new phone BEFORE acquiring any and all recovery tools, especially from a new manufacturer (I'm used to HTC).

Hi guys, in need of your help. I was originally on H91810D rooted and decided to try and install the OTA update not knowing that I would get stuck in a TWRP loop. I've downloaded H91810j KDZ file along with both LGUP and LG Bridge to try and flash the KDZ onto my phone, but neither UP or Bridge detects my phone connected to the PC, but Windows 10 detects that my phone is connected. I'm stuck sitting in TWRP and no matter what I try, it won't work. Any suggestions on what I can do to get through this? Any help is appreciated. Thank you!

Root Guide for Lg G5 Tmobile on 20i Nougat?

So I've been doing a little bit of research, trying to figure out how to root my phone. I read I needed to downgrade my Security patch to something lower than 20i. I can probably figure out how to root it if I had a guide to downgrade my phone. Anyway I thought I'd ask this amazing community for some help! Thanks guys!

Just follow the steps to flash 20a in that thread with LGUP. No other steps required. Just do a factory reset then flash 20a then root. If your phone is buggy after flashing 20a do another factory reset then root. After rooting you can follow the guide to flash 20i using TWRP.

thank you so much

I have previously tried to root after I went to 20l but wasn't successful. I read about how I needed to downgrade to 20a, then root. However, I had errors when I tried to install the 20a KDZ file with LGUP. My bootloader is unlocked. Does anyone know if you can successfully downgrade and root from 20l?

Update, I was successfully able to downgrade from 20l to 20a, root, then flash autoprime's 20l zip via TWRP. Here is the shortened version of the steps I used.
1. Turn off virus scanner
2. Have latest SU, No verify zip, and 20l flashable zip on SD card
3. Factory data reset on current version (was 20l)
4. Developer options enabled
5. Turn on USB Debugging
6. Plug in to computer, prompt comes up on phone, accept
Do all the steps to unlock the bootloader (mine was already unlocked since I previously tried to do this)
7. Run “Upper Cut” (after LGUP installed)
8. “Upgrade” with 20a KDZ
9. Now on 20a, fresh install, go back in and enable developer options
10. Turn on USB Debugging
11. Plug in to computer, prompt comes up on phone, accept
12. Use Minimal ADB and Fastboot to run all the commands from this post https://forum.xda-developers.com/tmobile-lg-g5/development/root-h830-20a-nougat-lg-g5-hard-t3542496
13. While in TWRP, wipe data, install op sys, install SU and no verify zips.

Quick question, i am using t-mobile H83020i only GSM network, if i downgrade to 20a do i lose GSM unlock?
(I read a lot about people with that problem when downgrading)
