Hoping to bypass the TWRP encryption problem, I (stupidly) updated Magisk to 18.0 within Magisk Manager and now my phone will only boot into fastboot mode. It will not power off by holding down the power button alone or will not boot into recovery mode by holding vol up and power button (while in fastboot mode or after holding vol down and power until it starts to reboot then changing to vol up). I have tried to plug in my phone to my PC and reboot, still boots to fastboot. LG UP does not recognize it. I thought maybe running FWUL might give different results; same thing. Tried every fastboot option that I know of to no avail.

Are there any other options for me to get back into recovery/start the process over? Everything was fine except for the forceencryption and I guess I should have just lived with that..

Thanks in advance

Edit: After redoing vol up at different times during the reboot process (vol down and power while in fastboot mode), I got to TWRP recovery via download mode. Now to reflash stock and redo everything... I tried to simply reflash Magisk 17.1 and it errored out.

Edit edit: Downloaded stock 11g full ROM (https://xdaforums.com/tmobile-g6/development/h87211g-oem-flashable-rom-nougat-t-t3848254) and followed the instructions. Had to reboot back to recovery before flashing Magisk. All is good now! You're awesome, [MENTION=9374982]weakNPCdotCom[/MENTION]

I have tried every way mentioned to mount data in recovery without any progress. How can I perform a full backup if I cannot mount the data? Is it the firmware version/should I try 11h or 20a? If so, am I able to perform the same method as I did above with a full 11h/20a stock rom? Sorry for all of the questions and I appreciate all of the help I have received on here!

If I've updated to 20f on my H872 would I be able to revert back to 20e using LG up? I've heard there's no way to roll back :/ .
[T-Mobile LG G6 Guides, News, & Discussion] Ken C:
A format of data is considered to work. Not sure if it's that particular thread but I was having mounting issues myself and that op gives some deeper directions further down the thread.
[T-Mobile LG G6 Guides, News, & Discussion] weakNPCdotCom:
Where did you hear that? Pretty sure 20f is ARB01. you should be able to go back as far as 11g using the patched LGUP that runningnak3d linked in his root thread
[T-Mobile LG G6 Guides, News, & Discussion] cgregoryou:
I will have to try again.. I am just sick of reinstalling everything over and over. I prefer to simply restore an image back to how I had it. Would flashing the SysBoot with Patched Kernel + Magisk after flashing FullStock ROM remove the encryption? I am not sure the purpose of the patched kernel.

Thanks again for everything!
[T-Mobile LG G6 Guides, News, & Discussion] aquinoer:
if I'm on h8720f can I use this root method still???
[T-Mobile LG G6 Guides, News, & Discussion] Ken C:
I'm not super technical about the inner workings totally I'll put that right out there.

I'm running the 20d right now and can say that the patched kernel did fix it for me. I've been looking around and it seems that he did some stuff you'd have to wander all over to put together seperately to achieve the same result.

im having issues when trying to use LGup, can anyone help with this?
[T-Mobile LG G6 Guides, News, & Discussion] cgregoryou:
That is a patched app. You need to search and download LG UP. Then once you install it, replace the lgup.exe in lgelectronics/lgup/ with the one from the .zip download. You also need to add the common folder from the .zip to the model folder in lgelectronics/lgup/.

You can then open the app inside the lgup folder.

Edit: I attached an image to where it should go. I was on my phone last night and couldn't think of it all. Let us know if that fixed your issue.

Hi bros

I am have a LG G6 H87220A, after flash laf of H918, now phone can not boot to download mode. It show only small icon that mean booting to download mode then stuck, can not reboot, i have to unplug pin cable

Please help me how to recovery download mode. I tried flash laf stock from fastboot, no success. Thank you
[T-Mobile LG G6 Guides, News, & Discussion] Ken C:
Can you put up a pic?

I ran into the same issue myself months back and can't remember how exactly I got it working again. I want to say it was a reboot timing thing but I'd be lieing if I said it was a sure thing. Once you flash that laf the phone won't boot into the normal dl mode. Ie: you won't see that arrow circle deal, instead you get the little box with some blue dots, and for me it would take a little bit for it to actually fire up all the way. And I do believe, again if I remember correctly, that other than the fastboot reboot command those other commands tend not to work for the 872 version of the phone. Maybe somebody else knows how to boot to the laf twrp through adb. I still go back to that timing thing personally. adb would recognize the device and I could reboot from there and as it rebooted I'd do the cord + button combo and I was able to get back in there, but you need like 3 hands to pull it off. It almost sounds like you only got partway through the rooting process. But I'm just thinking out loud at this point.

Maybe something in what I said helps because I know how bad it sucks when it goes sideways on ya.
[T-Mobile LG G6 Guides, News, & Discussion] cgregoryou:
Flashed the FullStock ROM again (not sure if it was needed since I already flashed it) and then immediately flashed the SysBoot ROM w/patched Kernel + mroot. All is well in the world! No dm-verify or forceencryption. So much better and now I can do a full backup and try out different ROMs. You guys are awesome. If you're ever in OKC, beers on me!

Correct me if I'm wrong, but that's when you go to the next step. Read the directions the whole way through before starting a project like this.

Look at attached image and highlighted area.

Also, you mentioned H918 that you flashed. Did you flash the 20A file after like it mentioned?

[T-Mobile LG G6 Guides, News, & Discussion] Ken C:
I'm planning on updating to 20f and just in case something goes weird I was wondering if anybody had rooted that version using this method yet.

I have a couple roms downloaded that are built slightly differently, I had a major issue with encryption the first time through which is why I'm asking. One rom is set to take care of all that and the other is just that flashable stock version.

Any thoughts would be appreciated before I make the leap.
[T-Mobile LG G6 Guides, News, & Discussion] cgregoryou:
I think weakNPC mentioned it before, but is it ARB01? He said it should be fine as long as it is.
[T-Mobile LG G6 Guides, News, & Discussion] Ken C:
Ya it's his 20f.

When he first dropped it somebody had gotten an error flashing it so I had held off until I had the time to take care of things if they went sideways. And I got that other stock without all of weakNPC's stuff in it but with my encryption issues those builds give me interesting issues. His just tend to work but I hadn't heard anything more on the error issue that person had

I wish I could change my vote to no since I voted yes as soon as I saw TWRP. I don't think there's a way for me to attempt doing this over again since LAF is now TWRP?

System still doesn't mount, I tried it like 30-40 more times again.

Can someone who is more familiar with TWRP and this device tell me if it is safe to attempt backing up everything, deleting the system partition, formatting with TWRP then restoring the backup?

I normally wouldn't question doing this one bit but we're running the wrong TWRP on a phone with no roms, if something goes wrong with this I'm not very confident that I won't end up with a phone that has TWRP on LAF but is otherwise a brick.

Guys maybe i found a solution for the hard brick lg g6-g5-g20 but need a person very very good with linux after talk with a cousin of my friend work on qualcomm explane me a lot of stuff...doesn't give any file or anythink but tell me the solution is more easy than what we think.. give me a link of all qualcomm motherboard android.. and is in this link:

https://wiki.codeaurora.org/xwiki/bin/QAEP/release

and after a pdf to download where explane how to get the file to work with it...or maybe download the right think or understanding how can create android with qualcomm...im not good in script terminal or think...actualy i didn't understand nothink but my brother is informatic at first years of university and say that can be a good way if you know what to do

I'm also thankful for all of the hard work that has been done to get root on this phone. i am partially blind and afraid of causing a bricked device. I'm going to wait a bit to see if the process gets refined and custom Rom get released. Great job and thank you
[T-Mobile LG G6 Guides, News, & Discussion] slayer3032:
Awesome, tried restoring the system trying to get write permissions and it instantly failed.

Now TWRP needs a password to decrypt something????

My system partition is 10mb and it won't boot so that definitely just nuked system.....

So how do I recover from this now without LAF so I could at least start over? I can't mount anything and all of my backups are missing from internal storage which also seems to suddenly be encrypted or something stupid.
[T-Mobile LG G6 Guides, News, & Discussion] slayer3032:
Holy crap, okay ignore all that for the most part I'm finally rooted and booted.

I figured since it was already encrypted I couldn't do anything worse to the files that were on there. God help you if you hadn't backed up local copies of system, ect. on your comptuer ASAP.

I formatted again, wiping my latest backups but when I installed TWRP initially I backed up everything directly after formatting then copied it to my computer. So I decided to just format again and at some point along the lines I was able to get system mounted. I had to carefully wipe, shut down, go back to laf TWRP and it managed to mount system somehow magically.

I copied my TWRP backups, restored system which it fought me over attempting to unmount /system multiple times and erroring all along the way but I was able to adb in, flash twrp to the recovery partition then get the recovery backup deleted, and then install magisk. TWRP failed to unmount /system at every corner so I Imagine I'm going through hell and back if I ever have to touch /system again but I think I at the very least have root finally.

Make backups of everything, make as many as you possibly can at every possible step and absolutely in no circumstances keep them on this phone. I've never messed with these encrypted phones as my last phone was the G2, this stuff is a total nightmare compared to how well everything used to work.

[T-Mobile LG G6 Guides, News, & Discussion] FCORivers:
I'm guessing that the 918 laf is very similar to 872 laf in size since it can be used, so would it be safe to flash 872 laf in step 1 as a test to see how long, more or less, it takes to flash just that one partition as to have an idea since every computer is different given the fact that everything else would be exactly what is already in the phone? Maybe that way you'll know when to pull the cable before you actually attempt to get root.

I kinda want to do it but at the same time this ish is complicated, lol
[T-Mobile LG G6 Guides, News, & Discussion] slayer3032:
Flashed it and it works great! Unmounted and remounted /system like 50 times, backed up everything, copied it to my computer, wiped system, cache and dalvik restored system and flawlessly booted right back into system! :good:

How difficult would it be to replace the twrp version used in the op with this other before doing anything?

The upside is you can flash the image directly from TWRP once you get a version with working visuals

I'm actually sitting down setting everything up right now. What you mentioned had crossed my mind since that post.

I'm probably way over thinking it. Been out of the game since I got this thing so I'm a little rusty and don't want to make a stupid mistake.

Bricked my phone :(

I seem to have misunderstood this part

I saw the phone go through the laf, it went through the process for flashing two other partitions within about 2 seconds before I could pull the USB. It only got to the "laf bak" partition.

How do we flash the H872 KDZ without shutting off the phone and going back into download mode? Trying to go back into download mode after flashing the laf partition seems to have bricked my phone.

Obviously I took a risk and suffered the consequences. Would I be able to send this to LG and pay to have them re-flash whatever I messed up? Or is there anything I could try before that? The phone was briefly recognized by windows as a qualcomm 8000 something. Now nothing.

Any suggestions/help is appreciated.
[T-Mobile LG G6 Guides, News, & Discussion] cgregoryou:
If you prefer before it flashed system you should be fine. Did you exit and reopen LG up and do the h872 KDZ right after?
[T-Mobile LG G6 Guides, News, & Discussion] WindowsDOS:
I couldn't flash it. The phone wasn't being recognized by LG UP. I can't boot it or get to download mode.

My mistake was I thought I had to turn off the phone and do the process for download mode before I could flash the h872 kdz. I guess I was only supposed to close LG UP and then redo the process.
[T-Mobile LG G6 Guides, News, & Discussion] cgregoryou:
Yes, you were just supposed to reopen LG UP, not restart your phone. Can you get into download mode by plugging your phone in and holding vol+? You might try different USB ports and different cables. I'm not sure if that will help.

What is happening when you boot up your phone?
[T-Mobile LG G6 Guides, News, & Discussion] WindowsDOS:
Nothing. I can't get it to respond to any button presses or combo's.
[T-Mobile LG G6 Guides, News, & Discussion] Ken C:
A thought if all else fails, may or may not work, but the phone is going to die eventually right? (I actually had to do this at one point) after it dies do the cord +button deal, but plug the cord into the pc first and see what you get.

Like I said just a thought.

Have lgup started before you do this, it'll give you a "no handset" msg at first, when it grabs the phone lgup will automatically do its thing and go to the flashing screen. Maybe you'll get lucky. I want to say I did something like this once myself and if nothing else it shouldn't hurt anything I would think.
[T-Mobile LG G6 Guides, News, & Discussion] cgregoryou:
Is it stuck on? Does it power cycle? Can you hold vol- and it restart? I'm trying to figure out what state it is in. Pictures help.
[T-Mobile LG G6 Guides, News, & Discussion] WindowsDOS:
A picture of the phone won't help much. There's no buzzing, sound, backlight, or anything to indicate it's working. One thing I noticed is my wireless charger does detect the phone and start charging it. I was able to get the following info from dmesg in linux when I tried just plugging it in, vs trying to do download mode.

[T-Mobile LG G6 Guides, News, & Discussion] cgregoryou:
None if those links did anything. Have you let it die like Ken C mentioned then holding vol+ and plugging it in? Another option, not sure how hardware savvy you are, is buying a busted up H872 on eBay and swapping the innards.
[T-Mobile LG G6 Guides, News, & Discussion] WindowsDOS:
That's what I've decided to do for now. I found a working one with just a broken screen and scuffed outer case for $63 surprisingly. I'll let you know when I get around to rooting that one the right way ;). Thanks for the suggestion. I didn't expect them to be so reasonably priced.
[T-Mobile LG G6 Guides, News, & Discussion] cgregoryou:
Just be careful taking them apart and putting it back together. There are a lot of small connectors in there. Should be pretty straightforward though from the videos I've watched. I bought a perfect conditioned G6 other than a broken SD card reader for $89. I looked into replacing the SIM card/SD card reader but decided to use a USB-C flash drive to transfer data for now.

I just successfully rooted my H872-TN (T-Mobile for USA) using this method, starting on 20f.

I followed the instructions for 20a, but substituted "20f" wherever applicable (like having a 20f kdz to flash after flashing the H918 LAF).

The process went exactly as it did on 20a.

Hmm, well MidnightCore didn't work for me, but I did figure out how to do it manually :) Pretty simple, actually:

Find a boot animation zip here: https://xdaforums.com/android/themes/alienware-t3721978 (or wherever)

With a root file manager, go to /system/media/ and replace the existing bootanimation.zip file with yours.

Optional: go to /system/media/audio/ui/ and replace PowerOn.ogg with your OGG startup sound file.
