Hi.

I followed the guide without problems up to the step2.sh , after which I got an encryption error upon reboot.

I followed the tip about wiping. I dont know if I did something wrong, but now there's no OS to reboot to, and there isn't the backup I made earlier. I'm currently manually flashing twrp and magisk. Twrp works fine, but I keep running into error code 1 when I try to flash Magisk. I looked it up on google, and found that it might be due to the twrp version, or lack of OS? I dont know. The twrp version says it is 3.2 30. Im trying to install Magisk v16.0.

What steps should I take next?

Edit: During the Magisk v16.0 installer on twrp, the step the error occurs at is as follows:

- Repacking boot image

! Unable to repack boot image!

- Unmounting partitions

Updater process ended with ERROR: 1

Error Installing zip file '/sdcard/Magisk-v16.0.zip'
[LG V20 Guides, News, & Discussion] cnjax:
Sounds like you have no rom installed, thus no kernel, so there's nothing for magisk to modify, so boot into twrp make sure you format data not just wipe, flash rom, immediately flash magisk then boot
[LG V20 Guides, News, & Discussion] Dontblameda1:
Hey man, I had the same exact problem. What [MENTION=4201835]cnjax[/MENTION] said is right though. Although because of the problem I had, I flashed Alpha Omega onto my phone which installs magisk for you, so it made it a bit easier. The people on this thread recommend the Mk2k kernel, but that flash wasn't working for me so I had to choose another kernel in order for it work. I forgot which kernel I chose.

i think i broke my phone

hey guys so i was trying to downgrade my lg v20 tmo but when it rebooted after the kdz was installed it keeps saying "settings keeps stopping" and it wont load the secure start-up just keep syaing "settings keeps stopping" over and over what can i do
[LG V20 Guides, News, & Discussion] scorpio76r:
I don't think that you "broke" it but, we need more information as to what tools or precedures you exactly did. So that we may better help you.
[LG V20 Guides, News, & Discussion] ytmrj0k3r:
i think i broke my phone

ok i used LG up i flashed H91810i_00_1202.kdz and when it restarted this is where it started saying the unfortunately settings has stopped ive tried to flash different versions and same result (H91810i_00_1202.kdz)(H91810j_00_1216.kdz)(H91810k_00_0517.kdz)(H91810p_00_0717.kdz)(H91810u_00_0528.kdz) these are all the different version i tried to flash into my phone but nothing same message setting has stopped
[LG V20 Guides, News, & Discussion] cnjax:
Were you on 10p or later before you flashed the 10i kdz?
[LG V20 Guides, News, & Discussion] ytmrj0k3r:
i believe i was later i think i was up to date i was trying to downgrade to root my phone
[LG V20 Guides, News, & Discussion] cnjax:
Then there's your problem, on the 918 version 10p and later arb was incremented to arb1 so if you downgrade to a version earlier then 10p you have a brick
[LG V20 Guides, News, & Discussion] kish9046:
You should downgrade to 10p version for the lafsploit to work and to install twrp... download the kdz below and try flashing again...

[LG V20 Guides, News, & Discussion] ytmrj0k3r:
so i fixed it lol i just hard reset it and its working fine now so which version is able to root and which one is not i just want to make sure i can root my phone i dont want to mess it up
[LG V20 Guides, News, & Discussion] cnjax:
Problem is he already downgraded to an arb 0 version once that is done there's no recovering from it
[LG V20 Guides, News, & Discussion] kish9046:
you must be on 10p for lafsploit to work
[LG V20 Guides, News, & Discussion] ytmrj0k3r:
how do i find out what version im on?
[LG V20 Guides, News, & Discussion] kish9046:
Please read the first post... also please follow all the steps correctly and once you are done i would suggest a twrp backup just to be safe....
[LG V20 Guides, News, & Discussion] cnjax:
Wow that's the first time I have seen anyone who was on 10p or later, flash a pre 10p kdz and not brick, something is missing here

Hi [MENTION=4201835]cnjax[/MENTION] I think he never flashed to a arb0 from arb1... if he had, then he would have bricked as you said....
[LG V20 Guides, News, & Discussion] cnjax:
I agree with you, I hope he stops for a minute and carefully reads the laf exploit thread and this one before he proceeds any further
[LG V20 Guides, News, & Discussion] ytmrj0k3r:
so im on H91810p am i able to root?
[LG V20 Guides, News, & Discussion] kish9046:
Yes!.... [MENTION=9357607]ytmrj0k3r[/MENTION]
[LG V20 Guides, News, & Discussion] kish9046:
Yes you should be able to execute lafsploit and root your phone....
[LG V20 Guides, News, & Discussion] ytmrj0k3r:
ok just one more question is there a way to find out if im on arb0 or arb1?
[LG V20 Guides, News, & Discussion] kish9046:
10p and later versions are ARB1..

those below 10p are arb0
[LG V20 Guides, News, & Discussion] cnjax:
You're arb1 therefore the only root method is the laf exploit
[LG V20 Guides, News, & Discussion] ytmrj0k3r:
ok cool thanks a lot guys do yo u guys recommend any roms
[LG V20 Guides, News, & Discussion] kish9046:
Try alpha rom with mk2k kernel... i personally use it and has been very good so far... only stock based roms will have second screen capability.... if you are not concerned about the second screen, then try other custom roms like lineage or RR....
[LG V20 Guides, News, & Discussion] ytmrj0k3r:

[LG V20 Guides, News, & Discussion] scorpio76r:
No
[LG V20 Guides, News, & Discussion] Erikvio:
Thank you! I was under the impression that Magisk had to be downloaded first. I contemplated flashing a ROM first so I would have an OS, but was afraid of horrifically messing things up.
[LG V20 Guides, News, & Discussion] kish9046:
there has to be a kernal/rom for magisk to work.....as [MENTION=4201835]cnjax[/MENTION] mentioned... so no bad in flashing a rom first....
[LG V20 Guides, News, & Discussion] kish9046:
NO..... you wil not lose your unlocked status after rooting and may i know where r u frm India?
[LG V20 Guides, News, & Discussion] scorpio76r:
I'm still sim unlocked on the H918. Did you loose root?

Hello,

My goal is to flash Lineage 15.1, is this the only way to get started if I'm on 10U?
[LG V20 Guides, News, & Discussion] cnjax:
If you need to root yes, if not then follow the instructions in the lineage thread
[LG V20 Guides, News, & Discussion] ognop:
I'm on H91810k and unlocked the bootloader I think (reboots give that Your device software cannot be checked for corruption etc). Enable OEM unlock ON, USB debugging ON, Verify apps over USB OFF, USB Config MTP (not sure if this matters).

Since it's 10k I presume that means it's ARB0.

So my question is, I should still download that H91810P kdz file and uppercut etc from part 1 of the first post? There's no way to preserve the ARB0? I was planning to just use stock rom, but will this prevent using Lineage?
[LG V20 Guides, News, & Discussion] cnjax:
Since you are 10k and arb 0 I think you could use the dirty santa method to root, once you flash 10p or later you will be arb1. Only use dirty santa if you want to preserve arb0 but be advised all the currently being maintained custom stock roms and lineage I believe are all arb1 now
[LG V20 Guides, News, & Discussion] scorpio76r:
Hello, I just wanted to know if anyone has been successful at getting native call record to work on either stock or alpha rom on the H918? I'm pretty sure that it may be possible on the lineage rom but, because lineage does not have working volte, it's not a option for me.
[LG V20 Guides, News, & Discussion] whitedavidp:
Hello all. I just got a new H918 and have been trying to work it thru this process. I have the bootloader unlocked and booted up into linux via rufus, etc. however, i cannot get past the git command near the top of step 4. It seems like the linux install has no internet access. i can't get anywhere via the included firefox browser and git fails. I must be doing something wrong but I don't know what. the computer is the same one I am typing on right now. so i know it has a good ethernet connection. please help. I saw elsewhere in this thread something about runningnak3d moving to gitlab and elsewhere found a link to something of his at gitlab. but doing the git against that also fails. so i think this is basically a networking problem. Thanks in advance for any help.
[LG V20 Guides, News, & Discussion] scorpio76r:
I remember running into that issue. What I did was download Firefox for windows 10 ran it for a minute (made sure that the internet was working and all) the I turned the pc off and, the booted FWUL from the USB stick. When it boots go to the Firefox browser there and sign in with your user name and password, you should be good to go from there and, it will work.
[LG V20 Guides, News, & Discussion] kish9046:
Didn't worked for me either on alpha.... i use 3rd party app for call recording though and it works fine...
[LG V20 Guides, News, & Discussion] kish9046:
you need a working internet connection to pull the resources and I'm not sure why your internet is not working in FWUL... i tried searching for a solution in the fwul thread and couldn't find one....

did u tried other internet options like usb tethering or wifi hotspot? ...
[LG V20 Guides, News, & Discussion] whitedavidp:
Brilliant! I did try again. I think the second time I chose forgetful mode in FWUL. Not sure if that made any difference but I was able to get to the internet and complete Step1. So kind of a mystery to me but... Thanks to all who responded.
[LG V20 Guides, News, & Discussion] scorpio76r:
You are welcomed, I'm glad to hear that you succeeded.
[LG V20 Guides, News, & Discussion] ognop:
Alrightey, finished the instructions in the first post (from h91810k), unlocked, fwul'ed, flashed, etc. Thanks!!

Then tried to follow the second post instructions about switching thermal-engine conf file, then removed rctd (left ccmd and triton in because honestly one seems to have explained what exactly those do, even in the aik threads). Kcal tweaking failed however, the kernel aduitor app (both versions) don't list screen options as a choice so I guess that means I'm not on a kcal-enabled kernel. Any alternatives to that part?
[LG V20 Guides, News, & Discussion] scorpio76r:
You might just be better off flashing the alpha rom. It's better than stock.
[LG V20 Guides, News, & Discussion] cnjax:
The mk2000 kernel supports kcal
[LG V20 Guides, News, & Discussion] whitedavidp:
Sorry for more noob questions here.

Feeling somewhat unsure of myself, having completed step 1, I also wanted to run step2. So I unplugged after step1 and the device booted into Android. I let that all complete. I then went back into download mode. No matter what I tried, I kept seeing TWRP. Is this because the exploit actually places TWRP in amongst the download mode code? After several failed attempt to get/see what I was normally expecting to see upon entering download mode, I went ahead and ran step2 while TWRP was showing (but doing nothing). To my surprise, it seemed to run to completion ok. But then upon reboot I got the encryption problem and was put back into TWRP where I formatted /data, wiped the caches, rebooted. Android booted up and I was feeling ok. But a root checker said I was not rooted. So I figured that step 2 maybe did not complete right. So I booted into recovery mode, saw TWRP, and flashed Magisk. After rebooting the root checker said the device was rooted but no root management app. And attempts to issue su command in terminal emulator failed with permission error. So I installed Magisk Manager app and now I seem to have root.

Not only am I new to this device but I am also new to Magisk. I have always just used SuperSu in the past on all my other devices. So is there anything else I must be doing at this point? I have disabled auto system updates in the developer settings. Do I want to update past 10p? Or to preserve all this must/should I stay at 10p?

Thanks for you time and patience.
[LG V20 Guides, News, & Discussion] ognop:
Guess I'll look at that mk2000 later then. Thanks!

In the mean time, I rebooted the phone for no particular reason and upon bootup I got a toast saying I don't have ROOT. Magisk Manager wouldn't run, and Root checker confirmed there was no longer ROOT on the device.

Rebooted a second time, and everything was back to normal (rooted). What just happened?

Edit: rebooted 5 more times, kept root each time. Weird.
[LG V20 Guides, News, & Discussion] kish9046:
Yes the lafsploit process would replace the download mode to twrp..... After rooting, you should not take a ota update...

If you would need the latest update (10p), i would recommend flash the alpha rom.... And regarding magisk, just ensure it is updated to the latest version and finally do take a full twrp backup of your device before doing anything....

Cheers
[LG V20 Guides, News, & Discussion] kish9046:
It did happened to me once :confused:and i had to flash magisk again to get root....
[LG V20 Guides, News, & Discussion] BROKEN1981:

No need for any custom stock ROM's.

It's easy to just debloat what ever you want to.
[LG V20 Guides, News, & Discussion] whitedavidp:
Thanks for the clarifications!
[LG V20 Guides, News, & Discussion] kish9046:
Luckily i never faced any issues so far running alpha with mk2k kernel.......

and yeah the twrp flashable 10u could be a better option if one needs to continue with stock and be rooted and updated after lafsploit....
[LG V20 Guides, News, & Discussion] kish9046:
Updated in the first post... and does this comes with an aroma installer like alpha to debloat the rom?

[LG V20 Guides, News, & Discussion] whitedavidp:
Perhaps there is a better place to ask about this but the folks here have been kind enough to help this noob. Now I think I am a noob in trouble. I was trying to install a Magisk module for xposed and things have gone way awry. The phone can be booted into download/TWRP and into recovery/TWRP. But otherwise it gets ONLY to the T-Mobile logo and jingle. It then sits there - seemingly forever. Will not respond to the power button and battery removal is required.

Thinking I may have hosed up all my work until now (of course, no backup), I decided to try to re-install 10p and start over again. While in download/TWRP I tried running uppercut but LGUP ends up not seeing any attached devices. I have the LG drivers installed. So that's not the problem.

So I am stuck. Don't know what to do/try next. Perhaps there is a 10p firmware that is flashable in TWRP and that might work? Your suggestions are very much appreciated. Thanks
[LG V20 Guides, News, & Discussion] kish9046:
R u still able to boot to twrp? if yes do a full format and try flashing 10u zip(link below) .... remember to root before booting...

And make a back up which you should have done before flashing mods.
[LG V20 Guides, News, & Discussion] whitedavidp:
Thanks so much for your reply/help. This is way over my pay grade :)

I can boot into either download mode or recovery and I get TWRP in both cases.

I was under the impression that 10p was the last root-able version and I installed that as part of the procedure in this thread. So it seems like if I am not careful doing this I may be unable to get rooted again. Is that so? So I want to be sure that I understand what you are meaning when you say remember to root before booting. My device was rooted following this thread's instructions and Magisk was installed and working. So what must I do to root before booting?

Sorry for being so dense...

---------- Post added at 06:53 PM ---------- Previous post was at 06:51 PM ----------

I know better but still hosed-up by not doing so. Is there any point in doing one now? The device seems well hosed up. Thanks
[LG V20 Guides, News, & Discussion] kish9046:
lafsploit works only with 10p, so this is the reason for downgrading to 10p before executing lafsploit.... the sole purpose of lafsploit is to instal twrp recovery onto our device...

after installing twrp one can easily root or flash roms as per their need.....

Now that you are able to boot to twrp, you can flash any custom rom or root like with any other device with a custom recovery installed....

just flash the 10u zip, within twrp, available in the link i shared above and flash magisk immediately after you flash the rom before booting to system.

This has been the only rom that I have been on since rooting, thanks to all of you guys. I'm just out for stability and, customations etc, If I can help someone, I will try my best. I don't think that we should look any further than the development of Android.
[LG V20 Guides, News, & Discussion] whitedavidp:
Sorry, one more question... Sometime after flashing 10u, installing Magisk, etc I booted myself into download mode. Originally, after following the procedure in this thread when I did this I found TWRP in boot mode rather than the original download mode. I understand this is by design. But now when I went into download mode I find the original download mode stuff and no TWRP. Is this to be expected? Thanks

PS - I lied, here is yet another noob question... Since I am now using Magisk instead of SuperSu, is there any need for me to include System in my nandroid backups? Since it seems that I cannot modify System, I don't see why? When you are taking nandroid backups, what are you including/why?

Cheers!
[LG V20 Guides, News, & Discussion] cnjax:
Backing up system is still a good idea if you want to restore and not have to flash the rom over and reset everything up. And some mods you might load will modify system.
[LG V20 Guides, News, & Discussion] whitedavidp:
Thanks much. But then to restore system using nandroid don't I have to tell TWRP to allow system writable? If so, doesn't this destroy the main idea about Magisk/Systemless root? I am so used to the old SuperSu way of doing things, I don't want to go through the learning curve of Magisk if I loose what seems to be a major advantage. Sorry for all my noob questions. I appreciate the help. Cheers
[LG V20 Guides, News, & Discussion] cnjax:
I don't use magisk, but my understanding is twrp loads it own kernel and root shell to perform its task therefore it should be able to restore without issue unless there's a problem with the backup itself.
[LG V20 Guides, News, & Discussion] whitedavidp:
Just a note to other noobs: What I thought was a soft brick after installing xposed for Magisk was not at all. It seems that on the first book after installation you have to expect to wait maybe 20 minutes for the boot to complete. Not clearly documented but I saw some notes to this effect elsewhere. So I tried again as was patient. It took about 20 minutes of staring at the TM logo but the boot finally did complete. So BE PATIENT. Cheers

Flashing the FWUL did not work on any settings whatsoever for the laptop I had on hand. (turned off secure boot, tried both legacy and UEFI etc)

Ended up taking the image file. renaming it .iso and loading it up via virtual box which worked just fine! Had to tweak the usb filters a little bit (I had to add a generic one with no specifics) and the prompt for step 1 worked and TWRP was installed perfectly.

Coming from a 10k rom to 10p kdz for the flash and now using a 10u super rom from dudeawesome (even though the instructions say use a different TWRP the one provided works just fine)

Just last month I wasn't even sure this would be possible. But I messed up earlier today by installing a TWRP version meant for a different LG phone and soft bricked it. 10p KDZ fixed all of that pretty easily.

THANKS FOR THE POST! (I was lost with FWUL for a few hours which is why I am posting my reply, hopefully works for everyone else)
