I just got this phone and I'm debating on unlocking the bootloader and rooting it and I was just curious if in the future I need to return it to stock (especially for selling it in the future) how do you go about doing that? Do you just flash one of the stock firmwares though TWRP like I found here? http://downloads.codefi.re/autoprime/LG/LG_G6/US997/US997-USA/US99714a
Then what do you do if that is correct? Also how do you relock the bootloader? I'm sorry if these are noob questions but I have been out of the modding game for a good while.

Just flash a kdz trough LGup and the phone will be completely stock, no twrp and no root. Then you have to only lock the bootloader by typing "fastboot oem lock". Don't run this command while you have twrp and root!
Ah, and the fact you have relocked the bootloader doesn't mean that you recovered the manufacturer warranty, LG can easily verify if you used the unlock bin.

I did some searching and found this. Is it the correct thing? http://rootmygalaxy.net/download-latest-lgup-tool-for-lg-devices-flash-tool/
Also just to be clear I unlock my bootloader, install TWRP and root the phone. If I ever want to go back to stock for selling the phone or whatever I just download the latest KDZ file like I linked to above and then I flash it to the phone and it will return everything back to stock? Then after that you just do the relock command and the bootloader is closed again?
I appreciate your help. I just to be super clear.

Pretty much yes, search for uppercut if you have driver problems with LGup, and for firmwares this is the best site to download them: https://lg-firmwares.com/lg-h870-firmwares/

Ok then
LGUP
Hi, so I started flashing the kdz on my LG G6 using LGUP and it starts, but then randomly quits out. It's recognising my device and the file is definitely the correct one. Any hints as to why it's not working?
EDIT: I managed to fix it, apparently Windows Defender was seeing Uppercut as a virus and stopping it from creating the files it needed to. So make sure you turn off Windows Defender when you do this.
My experience with returning phone to stock is bad. First unlocked bootloader, installed twrp, bootloader for havoc ROM and ROM itself..
Havoc 3.1 OK, but BT calling not working, so I decide go back to stock.
LGUP used without problem, but then camera neither flash ligh doesnt work anymore.
Last firmware for H870 used from official.
Have someone same shi t experience like me?
Trying everything, but no success.
So its not easy go back to stock again..
(My phone is H870 for EU)

It's a known problem, the A10 ROMs somehow mess with files needed for stock camera that aren't included in stock pie.
You have to flash Oreo bootloader and then 30b zip for the camera to work.
If that doesn't work flash Oreo kdz and update to Pie.

Problem finally solved!
Tried many times flash Oreo bootloader and then 30b(pie), 20a (oreo). With 30b everythings work except camera. With oreo 20a phone wasnt even bootup normally.. (after reset just screen with green android and message "No commands" appear. I used LG UP 1.14 with Uppercut.
Then after many unsuccesses I put phone to state where bootloop appeared and I thought about to throw it into garbage.
ADB shell and TWRP saved me... I was again able flash roms.
At the end I found some package with LG UP 1.14 and patch (so I could use it without Uppercut...there is a new LGUP_common DLL), and with this combination flash procedure worked smoothly.
BUT! I had to load nougat stock rom first (H87011i_00_OPEN_EU_OP_0108.kdz), which fix partitions in phone somehow (but there wasnt possibility upgrade higher). Everything, camera included was working with this rom..
Then I flash oreo stock rom (H87020a_00_OPEN_EU_OP_0423.kdz), and now It booted right (no "no command" during startup). Phone worked perfectly, and I used OTA upgrade to land on 30b pie last official update.. tadaaa
Hope it will help others with same problem..

Hi,
I've just got a new ZE551KL (z00td) with a locked bootloader and no root. Since the phone have the latest android 6.0.1 build I have difficulty to root it and unlock the bootloader. I did many research and I think it's really confusing. It seem to root my phone I need an unlocked bootloader but to unlock it I have to root my phone. The last interesting thing I've found for my phone is to flash a pre-rooted system.img & boot.img ( http://www.asus.com/zentalk/thread-80274-1-1.html ) but I also get stuck here since the guide tell me to flash both and I can only find the system.img.
I would like to know if there's any guide to root & unlock my bootloader on my ZE551KL. Thanks a lot!
It's a pain, but you may have to roll back to an earlier version of the firmware...back to lollipop. There are instructions in one of the threads on how to do that. I was able to unlock before the marshmallow update with the official unlock utility from Asus. Once you are unlocked, the easiest way to root is just to either boot twrp.img (previously downloaded and extracted to the adb folderon your computer) using fastboot (lots of threads here with instructions, too) and install supersu.zip. Or if you want to install twrp as your recovery, you can flash it from fastboot, then flash the zip of supersu. If you need more help, I am no expert by any means, but I have done this with my own ze551kl and might be able to give you some more hints.
Personally I would avoid the prerooted images as I had a lot of trouble with them and nearly bricked my phone by trying them out.
Thanks a lot for your reply! That's what I'm trying right now. I'm rolling back to lollipop from an official rom file from asus website. So far, I tried to flash it with stock recovery but it said that I cannot install a older version on top of a newer one. I did an downgrade of the recovery and now I'm waiting for the flash.

Excuse me, how did you do the downgrade of the recovery? Can you share the .img with me? I have TWRP installed with locked bootloader
I've found older stock recovery on this site : https://mega.nz/#F!lodnzDhK!H5ChxausDTyko1qGlnF7dw!Fg9FwLoa
Credit to ThanveerAliSayed in XDA
Well it seem that I cannot downgrade, the latest recovery don't want to install a lower version and when I try to get a older stock recovery I still cannot downgrade since it get stuck at verifying image update package.
Also I've noticed that my version is 21.40.1220.1698 and so far I can't find anything related to this version for rooting or unlocking bootloader. Even the official firmware on asus website for the ZE551KL is older than this version and I couldn't flash it. I had to get it from https://asus.kremowka.xyz/categories/show/2 because I've soft bricked my device. I'm still trying to find a solution...

I would NOT use this stock image for ze551kl. There is one for the 601 and the 550 but not 551kl. I will find the thread with the first stock recovery posted that I used and post the link in a while. Give me a chance to find it. I would roll back to it, then upgrade to the stock firmware listed in the unlocker notes. Once it's unlocked, you can go to the last lollipop before marshmallow and flash it. I would then factory reset, then flash marshmallow. After you have it working, then flash twrp (or just boot it in adb) as I said above and flash supersu.
I will warn you that a lot of people have had trouble unlocking and this might not work to unlock.

There are a lot of people in this forum that can help and most are pretty patient. Don't give up.
Finally I got my phone unlocked and rooted and it was too easy ...
I used fastboot to flash TWRP ( http://forum.xda-developers.com/zen...e601kl-official-marshmallow-wwv21-40-t3424903 ) and after that I flashed the latest CM13 from TWRP to gain root and unlocked my bootloader with this guide http://forum.xda-developers.com/zen...de-unlock-bootloader-asus-unlock-app-t3405850
I never though I could flash TWRP with a locked bootloader but it worked very well.

Me too the first time I tried to unlock my bootloader in CM13 it didn't worked. I followed the guide and I did this :
Phone connected to the computer with USB debug and using ADB :
Code:
adb shell
su
Then I followed the backup procedure and I did the magic command to unlock it :
Code:
echo -ne "\x01" | dd obs=1 count=1 seek=16 of=/dev/block/bootdevice/by-name/devinfo
After I rebooted in fastboot so see if my device was unlocked but no it was still lock. I did two adb reboot with these command :
Code:
fastboot oem adb_enable
fastboot oem adb_enable
You have to do these twice.
After this my bootloader was still locked but I did a normal reboot and tried the magic command and voila! Bootloader unlocked.

The video is for the 550 but the process is the same for the 551kl (zootd). I downloaded the stock firmware at the bottom of the page on the Asus support page https://www.asus.com/support/Download/39/1/0/23/SZCx58yhB5Jst0yI/32/ , extracted it, grabbed the boot.IMG from there and put it on my memory card along with the stock recovery from the link above (renamed it recovery.img) and the full firmware (drag the original, leave it zipped). Then I did as the video says and wiped in twrp, flashed the boot and recovery, wiped cache, then flashed the firmware. It took awhile for the process to complete. Hope this helps.

For the stock MM yep I did it. I just installed the stock one after my bootloader was unlock and followed a tutorial here for root. I really like the stock Asus, way better than the samsung with touchwiz in my opinion.

So, to recap. If you are at the latest update, and have never previously unlocked bootloader or rooted your phone. The ASUS provided unlock tool won't work on the latest update. With it locked you can't install custom recovery or downgrade the firmware to an older version so that you can unlock it. Catch 22. Screwed until ASUS releases an update to their unlock tool or someone figures something else out. Or am I missing something? Cause I've been trying to do something with my kids phone for two days now and no luck here doing anything. Bout 8 million guides and files around the net and none of em seem to do squat in my situation. Any comments? Let's hear em.

I flashed the 10s update to h918 and very stupidly forgot to flash root so I'm stuck on unrootable 10s. I want to lock my bootloader so can at least have Android Pay working, if i lock it can it be unlocked again or do i have to wait for a root method for the new 10s software?

I think you can unlock /relock as many times as you want. Root take place after unlocking but you can't do that anymore.
I rooted my v20 f800l a few months ago using dirty Santa method. Everything was going fine until I decided to reset my phone via twrp. I selected system, internal memory, cache and ended up without an os with only access to twrp. I had a nandroid backup but twrp couldnt read or detect the nandroid backup files. With nothing else left to do i flashed it with a kdz file version 10e using lgup software. Now I have my phone running fresh os very smoothly but the bootloader is locked and root/twrp is not there anymore. Now I plan on rooting it again as I'm still on 10e version but I'm not sure if there is a bootloader lock/relock limit, I've already unlocked bootloader once and locked it once, can I do it again? Or is there a limit to it? Please help

Can't you just install the official LG suite software on a desktop or laptop and then use that? It will probably detect the missing or "damaged" recovery and then automatically "repair".

Now I'm on stock rom with stock recovery, but the "fastboot oem lock" leads to a "corrupt device" that will not boot anymore. Can't the H870 (europe) be relocked, once it was unlocked via unlock.bin?
Isn't that the exact same procedure but then simply choosing "lock"?

From the LG developer site:
4. Once unlocked, it cannot be undone.
There is no turning back once you have unlocked the bootloader. You will not be able to revert your phone to locked status.

I'm interested in buying a LG G6. Can you please explain a little bit more what you did to re-lock? Where did you get the kdz image (which region) and what steps did you do? I'm completely new to LG devices.
Hello,
Recently i installed flumics rom on my phone and everything was fine but today i wanted to go back to stock rom and it seems i can't.
I installed the latest lg usb drivers and downloaded the latest lgup with uppercut
When i try to install the kdz file from the lgup everything is working fine and it finished 100% then the phone reboots and stucks at lg logo then after a while it reboots again and same thing stucks again.
ALso when i try to flash the kdz file again in the lgup it shows Fulmics rom 1.6
Tried to do a factory reset from lg recovery as well didn't help
Don't know how to turn off the device fully so i have some battery left.
Anyone can help me with this? do i need to send it back to lg?

Sadly the kdz files i flashed restored the stock recovery.
Also i tried the lg bridge as well but that didn't work either.
I have left the phone doing its thing for more than 45 mins, i guess that is not normal.
Use LGUP and Uppercut to flash stock. Need drivers and put phone in download mode. It will find the port and then flash the firmware.

I downloaded 3 different kdz files for h870 and none of them worked.
The strange thing is why after i flash the kdzs the lgup shows Fulmics Rom v1.6 under the version category.
Is there any way to flash recovery via download mode?
Enter bootloader and try to flash twrp again. Then flash the stock rom and all will be fine.

help me how to root + recovery h83020m
I just did it on mine the other day. I didn't realize that having an unlocked bootloader didn't automatically mean fastboot flashing would work, so I upgraded to 20m before I started the unlock and root process.
Starting from 20m, I:
1. Downgraded to 20l using LG UP + Uppercut from Autoprimes thread
2. Booted into android and let it do its thing.
3. I then used Uppercut to downgrade to 20a.
4. After I was on 20a, I had issues in android with items crashing, but no big deal... I was now able to use autorecowvery to install twrp.
5. Once I had twrp, I flashed the complete 20l zip from Autoprimes thread to get back to 20l, wiped data to get rid of the crashing issues, made sure I deleted the "recovery-fromboot.p" file, and then flashed magisk also.
6. Rebooted into a rooted 20l rom and continued on.
I will try then report back,thanks.

Those steps are right to perform the downgrade. If someone is interested in testing the new firmware from tmobile (h83020M), I have created a beta version of my Nimax Rom which has root, xposed and is compatible with asgard kernel.

Hello, I'm correcting some details and I could create an independent thread the other week if I have some time.

As I mentioned earlier, a beta is already available:
https://forum.xda-developers.com/lg-g5/development/rom-nimax-rom-1-0-h830-h850-t3710841
I now have H830 20m update zips Here.
I have completely stock Tmobile LG G5 with H83020M. I've avoided letting H83020N install so I can preserve the possibility of rootingby rollling back to 20A.
It's been officially sim-unlocked by Tmobile and I use it with ATT, and that's my question, will I lose that during rollback ? Since the imei is in Tmobile's database now I hope it wouldn't ?
