LG-G3 D851 - Can't Root and Can't unlock Bootloader - G3 Q&A, Help & Troubleshooting

Dear all,
I'm stuck and I don't know what to do.
I can't root my LG G3 D851 (T-Mobile) phone.
Recovery mode is only deleting the files (Original LG screen).
Purple, oneclickroot, kingroot they all fail cause they can't start in Recovery Mode.
I think that my Bootloader is blocking this, but LGUP doesn't recognize my Phone.
LG Flash no working DLL? I'm stuck and I'm starting to miss ODIN.
Is anyone able to help?
Cause I don't see it anymore

I have a variant of your phone, the LG G3 D858HK, I sort-of had the same issue and also found that KingRoot, Purple, etc failed, but Towelroot worked when I took the phone out Recovery Mode ..... after about the 10th attempt at trying to root using it that is...... Apparently it can take several attempts using the app before you obtain root

You can't unlock the bootloader. You have to downgrade to a lower version of lollipop, root with kingoroot, and run autorec.

LG G4 H815 SEA Stuck on LG Logo Screen

So i decided to unlock my h815sea bootloader, every thing went fine. I was able to flash twrp, flash android 6.0 with root and boot into system. I wanted to install xposed, i downloaded v78-sdk23-arm64.zip. I flash the zip and reboot into system. Now i cant go past lg boot screen. Could someone tell me how i can go into twrp? I am able to go into download mode, but LGUP application shows phone as unknown, can I use lg flashtool to flash android 6.0 kdz? OR am i able to flash android 5.1 kdz since i am able to go into download mode. I backed up everything using twrp and have all the files on my desktop.
nvm. I was able to go into recovery and flash genisys rom for xposed framework. For some reason when i try to flash xposed on a stock mm file, phone goes stuck on lg logo.

When did you unlock your bootloader?
I would love to know the answer to that as well.

I was able to get the unlock key when lg accidentally enabled bootloader unlocking for SEA variant on their website. Didn't it use the unlock key until yesterday. Loving MM, so smooth.

There's a guy (shiboby) that is looking for the unlock.bin files to examine to see if he can figure anything out for them. Doubtful anything will come of it, but you may want to send him yours to see if it would help

As an owner of a locked H815 SEA, I would greatly appreciate him being sent this file haha. Or perhaps post it in this thread: [Bounty] [allready $2400+] Unofficial bootloader unlock

Rooting H815

I recently successfully unlocked bootloader on my H815 EUR version, v20a. I then proceeded to flash TWRP after booting into it from fastboot. I let the phone restart to make sure everything is ok. Then I went back into TWRP to flash SU. After that, I got a bootloop stuck at LG logo. Luckily I was able to use LG Bridge to flash back to stock and get rid of bootloop.
My question is, how come I got a bootloop? Is it worth it to try to root my phone again? I want to be able to use titanium backup to transfer stuff from my old phone. I also want to use xposed.

You probably need to unlock the bootloader, both in dev settings and again with fastboot. fastboot will wipe data

It's been a while since I used Fastboot.
Do you know the exact commands to unlock the bootloader?

Regarding root access, this thread

Explains how tho get root on a similar phone like LG k10 using kingroot. Other members have told me I don't have too unlock my boot loader before attempting too gain root.
Do you know if there is any truth in that?

No you don't need to unlock your bootloader to root your phone. Some devices need it.
I bricked my phone while replacing KingRoot with SuperSu. I don't trust Kingroot, removing KingRoot method for LG K10 for now.

http://forum.xda-developers.com/lg-k10/how-to/twrp-root-lg-k8-k350n-t3475807
If you stop at "Your device ia corrupt... " Just use LG Bridge, works well!

unlocking the bootloade voids your warranty.. only way is to send it to LG... or used the modded KDZ to disable big cores... in case you ncaat fix it. or get new motherboard..

bootloop not software but hardware... but you could try flashing KDZ using LGUP. ive seen some claim theirs worked after flashinf stock firmware if it continues then hardware but most likely its hardware..
mines is unlockable.. and trying to keep it that way for the same reason... ive seen a post that says it can be relocked...
heres is the post.. i would like to ask you a favor if you try it.. make video of it .. to prove it works..

This is the reason why i swap my G4 H818P to Korean Variant G4. The Bootloop problem. Korean Variant is perfect for me. Strong 4G signal and no more SMS Limits in Marshmallow official update.

LG G4 VS986 Root question. 2BA or 13B

Hey guys. I had a VS986 back when it was 13B and all I did was downgrade to stock with LGUP and i flashed a rooted stock room, i remember doing something with chainfire "Flashfire" at the time because there is a locked bootloader issue and a custom recovery is not available..?|
Well now i have a new LG G4 VS986 that is 2BA. Can I root the 2BA or do i need to use the LGUP to downgrade to a specific version (like 13b?). And then what is the rooting procedure? YES, I tried to look it up, but i havent been following development for so long I am out of the loop and so much info from the gate is ALOT to take in.
So can someone PLEASE give me a quick run down of the rooting VS986_2BA procedure, and I can figure it out from there- Im not asking anyone to do the work for me, just alittle help. Or a link that could point me in the correct direction. I just dont want to have a new brick! Thank you!!
If you want to root 2ba you need to unlock the bootloader
https://forum.xda-developers.com/g4/general/unlock-unlock-lg-g4-device-usu-t3760451
Make sure you read the instructions and warnings because the bootloader unlock is permanent!!
Do not flash the baceband packeage you don't need it and your SIM won't be detected after flash
After you do that you should know how to get to fast boot mode and you need to flash this patch boot imge https://drive.google.com/file/d/1GH00BeWsEtKE2Ea34dXLmeMUC4Ts8XEI/view?usp=drivesdk
Here's the command
Fastboot flash boot (filename).img
And that's it all you have to do is install Magisk Manager from the play store
If you need any help please quote me

Not as of March 2018. https://forum.xda-developers.com/g4/general/unlock-unlock-lg-g4-device-usu-t3760451
I did it to my Verizon LG G4 and am now on Marshmallow, rooted by Magisk, and running XPosed. It's not a "double-click, next, next, finish" process. Read the entire OP in that link. And here is my summary of what I did https://forum.xda-developers.com/showpost.php?p=76691955&postcount=1063.
Oh wow that's awesome, I didn't know that was possible. But since you personally confirm it then I'm going to check out those links!
I wish I knew about this a month ago, I just downgraded mine and my girlfriends phones and flashed the rooted 13b system images.
Thanks for the info! ?
