Has anyone rooted a US996 and use a ROM successfully? If so how?!

i am very frustrated, I get into TWRP again and again no matter what i do. Bootloader unlocked, I can finish the dirtycow rooting, flash SU, and a ROM. And then.
I am greeted by TWRP.
There is this one time I booted up the WETA rom, i didn't like something so I reflashed the room, thus beginning my TWRP bootloop nightmare...

Are you saying that after flashing rom your device is rebooting constantly into twrp?

Want to relock bootloader

I tried to root H918 T-Mobile, and ended up with just an unlocked bootloader, and no TWRP install.
I'd like to re-lock the bootloader, but I can't find any instructions. Any unroot instructions I've seen, include using TWRP.
Thanks!

Same here, before i ended up bootloader unlocked. Well decided to relock the bootloader
Just fastboot oem locked

Try this method. As far as I know everything is back to stock at least it acts like it is.

Old thread but i found it while trying to restore my US996 back to factory. The kdz method works then you just run the fastboot command to relock the bootloader. Amazing it was that easy to relock the bootloader....

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

Returning to Stock

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..

Soft bricked my H918 trying to upgrade, need some help.

I tried to upgrade my H91810j (T-Mobile variant) to 10p using a flashable zip without recovery in it that I got in another thread on here. I made a mistake and wiped /data instead of factory reset and it would only boot into TWRP even after flashing the new file and an old file, I also wiped all my backup files (stupid me) so I've tried everything from flashing kdz and flashing zips but I eventually lost recovery (I can't boot into recovery, twrp or stock) and I couldn't flash it with fastboot because I locked my bootloader (several times unlocking and locking and all of a sudden it no longer wanted to unlock) and LGUP tells me I'm on 10j but I'm told I can't flash anything because of ARB. Now while trying to flash something with LGUP the phone tells me I'm on 10p so I guess I'm incremented. I can't seem to flash twrp.img (renamed to recovery.img) with the modded LGUP.
Is there anything that could be done to save possible root and twrp (if it's still there) or am I just going to have to save my phone by using the stock KDZ to go to 10p or newer rom? I really want root on this even if it's systemless (preferred type). Thanks in advance!

OKay I see, you might have to try to install LG bridge and use the recovery option to install h918 10q but you'll lose root because from what I see is when tried installing 10p it must have overwritten the os and failed to install 10p which means you might be stuck but if you can go into download mode then you might be able to use LG bridge to get into 10q latest os but not root atm. Or try booting into download mode and then try flashing 10j kdz

Thanks for taking the time to help me out. I just used LGUP and a 10p KDZ to flash it back to OEM stock, I'm hoping that by sticking with the older version someone may find root sooner or later.

yeah no problem, Also If we get root working on 10p that means it'll work on the latest version too as nothing has changed

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.

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 ?
