Sorry to bump this, but just wanted to see if anyone had some advice for my current situation.

After reading more, it looks like these might be possible options:

Flash /system to deODEXed rom

If there is a way to get ADB to work, I could possible restore download mode. But as far as I can tell, ADB requires IP and the phone to allow the connection. What about fastboot, any option there?

Flash laf.zip in TWRP from here and hope that download mode will allow me to restore 10p kdz to try the process over?

Flash a different rom (LineageOS 15.1, Super-rom, etc)

Attempt to unbrick-ish

Option 1: seems plausible, but the most recent posts on it don't seem very promising.

Option 2: seems less plausible because ADB doesn't appear to have a connect option without IP. Fastboot seems to have the ability to push --- maybe that could do it?

Option 3: might be good. But I make a lot of assumptions that I would be more comfortable if someone could confirm.

Option 4: may be my only option if there is no Stock rooted rom.

Option 5: seems very similar to option 4 but attempts to unbrick before flashing to custom rom

Again, just looking for some guidance and would appreciate it before I move forward. Feel free to let me know what options above are no good and what my actual options are. As you can see, I've been reading and just need a nudge in the right direction.

Edit: End goal would be stock rom with root & twrp
[LG V20 Guides, News, & Discussion] williamclarkonet:
Just wanted to throw my two cents in I got a LG v20 h918 from swappa and I wanted to root it as soon as I got it so I followed your guide step by step and it was no problem so I really appreciate you making guide it really helped a newbie out. I had the 20h verient so it was updated to the latest patch so I did have to downgrade it 10p but other than that it was pretty easy. a rooted phone is definitely the way to go
[LG V20 Guides, News, & Discussion] bamboozed:
I went ahead and did some additional reading and fixed my issue by flashing a new stock rom. I'll provide the info for anyone that might run into a similar issue.

1. Put the following items on an sdcard (20g-prerooted, latest twrp, latest mk2000 kernel, latest magisk)

2. Flashed TWRP to recovery. Reboot to recovery. Ensure TWRP version is updated; if so, continue.

3. Advanced wipe -> system, data, cache, dalvik

4. Install -> zip -> 20g-prerooted

5. Install -> zip -> mk2000 latest (2.1 in my case)

6. Install -> zip -> Magisk latest (18.1 in my case)

7. Reboot -> Wait for LG logo -> Wait for TMobile

After those steps I received a 'decryption unsuccessful' message. So I had to boot into TWRP -> Wipe -> Format Data -> yes -> reboot to system

Once the phone was functional, I booted back into TWRP and made a backup.

Now my phone seems to be golden. Hopefully this helps someone else out if they run into this issue.
[LG V20 Guides, News, & Discussion] 1337haXXor:
How do I just reboot into recovery? I think I've messed something up.

I did all the steps up to installing root, flashed Alpha Omega, and everything seemed to be fine except the SD card slot would not work at all. I think it may have had something to do with encryption, as during one of the steps in TWRP I saw a couple errors about "/data" So I'm trying to just boot back into TWRP so I can do the encryption fix, or even reflash the whole thing but I can't? Holding Vol - and power brings me to the Factory Reset menu, but saying "yes" both times actually just resets the device, I thought it was supposed to take me into TWRP?

So I'm wondering if I lost TWRP somehow because I hadn't yet flashed root, but trying the steps again, I can't install TWRP again, I get a bunch of errors and it retries 5 times before failing.

EDIT: Okay, I just did the WHOLE thing again, and with the addition of one factory reset after reflashing the KDZ (got the Settings Stopped Working repeatedly coming up bug), I'm back to where I was. Did step1.sh and step2.sh, flashed Alpha Omega, and though Magisk said it installed properly, the app is not on the desktop. I'm logging in now to see if it's at least installed systemlessly, but even still, how can I check if I do indeed still have TWRP (because I guess it got deleted the last time) without saying "yes" and "yes" to factory reset? Because if I don't, I have to do this whole process over again...

Final EDIT: Okay, solved it all it seems, I'll leave this here for anyone else who comes across the same issue (I've also deleted the error code, it's no longer relevant). When installing Magisk it installed it to the system, but not the app (Magisk Manager). I installed the .apk of the manager and that allowed me to give root access to programs, then a rebooter was able to get me into TWRP. Yay!

After coming from ao did your finger print scanner work
[LG V20 Guides, News, & Discussion] Cutecat42:
I'm not sure if this thread is still active or not, but...

I followed this post and successfully rooted. It's a different way than I rooted a year ago with this same model, so I don't know where to go from here. I want a custom rom/kernnel but I'm afraid I'll brick my phone because I don't know what I'm doing. I saw a post here where someone did brick their I one and the reply was basically "Did you really think a rom from 2016 would work?"

I don't remember the method I used last time but I know it was not magisk. Can anyone suggest an easy to install rom/kernnel? The stock rom is running really hot and missing the cool features I liked lol.
[LG V20 Guides, News, & Discussion] cnjax:
If you're looking for stock based then go with alpha omega oreo and for kernel mk2000 oreo kernel and flash magisk for root, use twrp, format data, flash ao oreo, I recommend flashing mk2000 separate from the option in the rom aroma installer then flash magisk. Otherwise if you want aosp then look for lineage 15.1 as it's stable. Los 16 is out but buggy
[LG V20 Guides, News, & Discussion] Cutecat42:
Uh...that sounds complicated. Maybe I can just use what I have. Any suggestions on how to make my phone run cooler without doing another rom? There's multiple apps on how to make the battery last longer, but I can't find any for the cooling.
[LG V20 Guides, News, & Discussion] cnjax:
You're heat issues are from the stock kernel, if you were able to complete this process to root the flashing a ROM, kernel root in twrp is easy
[LG V20 Guides, News, & Discussion] Cutecat42:
Okay. So I'm sorry for sounding like a complete noob but can you explain those instructions like I'm 5? Pretty please?
[LG V20 Guides, News, & Discussion] scorpio76r:
No disrespect intended but, no one is going to spoon feed you. The Alpha Oreo thread is still active. Many users willing to help you out there if possible.

I'm on Nougat. I was looking at lineage https://www.google.com/amp/s/xdafor...nofficial-lineageos-15-1-lg-v20-t3775689/amp/ and those instructions are confusing. I guess I'll just ask over there.

Hey there, thank you for the guide. I have zero experience doing something like this and I've a few questions. Apologies if I missed something. H91820h isn't mentioned so what should folks do? does it need to be downgraded? FWUL link is for 2.7 but the latest version is 3.1. Should the latest version be disregarded? Thanks you.

Little late to reply but for you, downgrade and use the latest FWUL
[LG V20 Guides, News, & Discussion] noddledizzy:
I messed up. So I did everything successfully until the wiping the data part. Stupid me thought that it was the wiping in the advance wiping part, so I did wipe everything including the rom. Since I am already at the latest TWRP, I just decided to just download and flash Alpha Omega. I was able to install it but it was giving me Decryption unsuccessful on boot. I tried going back to twrp to properly wipe the data(the one where you have to type yes) and the result is still the same, it is still giving me decryption unsuccessful. I tried a different rom. Just a prerooted oreo stock one and the results are still the same. Did me accidentally wiping my rom has something to do with this? and how do I solve this?
[LG V20 Guides, News, & Discussion] cnjax:
Try updating twrp, then wipe davlik and cache, format data, then flash rom, before booting then flash kernel (if you intend to use mk2000 I recommend flashing it separate from the one in the rom aroma installer, and then immediately flash magisk, then boot to system
[LG V20 Guides, News, & Discussion] noddledizzy:
Already did all this but, is it okay if I flash latest magisk?(19.3 as of this post) or am I supposed to flash magisk 16 that's linked in this tutorial?

I am also already on 3.3.1-0 (from https://xdaforums.com/v20/development/recovery-twrp-3-2-1-0-t3720239) are there more recent or more appropriate twrp to use?
[LG V20 Guides, News, & Discussion] cnjax:
Magisk latest should be fine, and that thread will have the latest twrp build

Flash a kdz or stock zip

---------- Post added at 01:36 AM ---------- Previous post was at 01:32 AM ----------

This one, just flash the 10p kdz to go back to nougat and then follow the guide. I recommend lineage 16 but if your sensors aren't working flash lineage 15.1 first, set it up, then dirty flash lineage 16. The sensors don't work on my H918 unless I flash lineage 15.1 then 16
[LG V20 Guides, News, & Discussion] rcboosted:
Is this thread still supported? I hope so. I ran into the encryption unsuccessful issue. I unlocked the bootloader, now every time I start up, it says it's unlocked, as well as verified via fastboot getvar unlocked, it showed unlocked: yes. I flashed to a fresh 10p using uppercut, booted up FWUL, double click on LG LAF (runningnak3d), git pull, git checkout h918-miscwrte, ./step1.sh All ran fine.

Then boot into OS, signed in etc, set up developer mode, allow oem etc etc, boot into TWRP by holding vol up and plugging in. ran step2.sh, it did it's thing, says TWRP flashed to recovery etc etc. I reboot the phone, and I get the encryption error. I tried factory reset using TWRP, tried advanced wipe of dalvik, data and cache, flashed Magisk. same thing.

I started over again, flashed lafrestore, flashed 10p via uppercut, and did everything again just to make sure I am starting from a known state. But same thing happened. What am I doing wrong?
[LG V20 Guides, News, & Discussion] kish9046:
just skip step2 and flash recovery and magisk manually... you should be good to go.....

Just to satisfiy my curiosity - how is it that fastboot oem unlock works for the H918. Is that all that is done essentially and the rest of the procedure is just about getting twrp installed. One other thing...how long does it take for the H918 to boot past the initial warning screen? I'm on dirty santa us996 and it takes a whopping 30 seconds. I'm wondering if the H918 is faster.
[LG V20 Guides, News, & Discussion] beerninja:
Guys I'm trying to flash over my existing TWRP old version to the current version 3.3.1 and it asks me which partition I want to flash to. I chose Recovery partition which worked but the only way to get there was to hold up on the volume button, plug in USB, it goes into old TWRP, then I choose reboot, then I choose Recovery.

Is there a way I can just get rid of old TWRP altogether so whenever I hold up on the volume control and plug in usb it goes straight to the latest version of TWRP?
[LG V20 Guides, News, & Discussion] mangokm40:
If you did the lafsploit, you have a version of TWRP in LAF partition and another in recovery partition.

Find the key combination to boot into recovery partition. You don't need the USB cable. I don't remember it.

When you boot to recovery, you should see the new TWRP.
[LG V20 Guides, News, & Discussion] beerninja:
Yep I was hoping to be able to get into TWRP with a button combination but I just learned that AO Rom erases the LAF partition automatically so it puts LG download mode back on VolUp + Power button.

The only button combos I know of are:

VolUP + USB plug = LG download mode (or LAFsploit TWRP if it exists)

VolDown + USB plug = fastboot mode

VolUp + VolDown + Power button = IMEI check

if there is some secret combo to enter recovery mode I would love to know :)

I just flashed AO Rom and noticed it kill my LAF partition so I downloaded a reboot app to reboot into recovery mode but I started panicking after none of them worked because I lost my root since I mistakenly flashed an older version of magisk from this guide instead of using the latest version. The reason I lost my root was because I kept tapping the upgrade magisk manager button haha. Anyway I was finally able to get back into recovery mode by using good old fashioned "adb reboot recovery" command

Now finally rooted and going to try the ps4 remote play which is the whole reason I rooted in the first place :good:

Having that same issue due to the same reason (tapping the upgrade magisk manager). except "adb reboot recovery" doesn't work. any ideas? also what version of magisk did you end up using?

on 10q : do I need to flash 10p first ??

Thanks a lot for this guide !! :). I am a bit confused though : I am on 10q and the original developper ( runningnak3d ) says ( https://xdaforums.com/v20/how-to/root-lafsploit-h918-version-t3773443 ) that I don't need to go to 10p first ... so do I need to flash to 10p first ???? :D maybe there is a valid reason I should go to 10p first ? thanks ! :)

[LG V20 Guides, News, & Discussion] cyberspectre:
I have two H918s. One is on software version H91810d, the other is on H91810k. At the beginning of this tutorial, it says all ARB0 software versions (H91810o and below) can use either the Lafsploit or the Dirtycow method. But the Lafsploit thread begins by saying "If you aren't on 10p or 10q, grab the H918 10p KDZ." If upgrading the software version from 10d/10k to 10p could potentially make the process harder, why do that? Is it necessary?
[LG V20 Guides, News, & Discussion] Snakecharmed:
Practically speaking, the latest custom firmware is all on ARB1. It doesn't matter how you root unless you're planning to use firmware based on 10o or older after rooting. After I rooted my first V20 via dirtycow, I ended up on ARB1 anyway when I installed 10s.

That prerequisite in the lafsploit thread is if you have a version newer than 10p or 10q and you want to use lafsploit, you have to downgrade.

If you are on ARB0, you can root via dirtycow.

If you want to use lafsploit while you're on ARB0, technically, you can't, because at the point when you will execute lafsploit, you'll already be on ARB1. Upgrading to 10p blows the ARB fuse and you won't be able to use dirtycow afterward.

Neither method was particularly difficult, but lafsploit does require you to install a FWUL distribution on a USB stick. One extra benefit of lafsploit though is having TWRP on the laf partition.

bootloader not unlocking

Hello everyone.

i am new here and i am sorry in advance if i did something wrong. i will come directly to the point.

model number: LG V20 T-MOBILE VERSION, H91820H, NON USA, Currently on oreo android 8.

we are not talking about any kind of roms kernels roots or anything here. just a simple question. " can this model's boot loader be unlocked ? like ever ? or not "

cause i have tried everything, when i say everything i mean everything. followed several posts on internet videos on you tube posts on XDA, tried using multiple PCs, multiple data cables, multiple drivers but for some reason i don't know what, this model's boot loader cannot be unlocked.

THE ERROR:

<WAITING FOR DEVICE> till eternity.

what i have done till now ?

1. lg drivers installed.

2. adb drivers installed with adb fastboot files.

3. updating legacy android adb interface driver, done.

4. went in to boot loader then connected the data cable and updated driver, done.

5. usb debugging oem unlock options activated, done.

6. restarted pc multiple times to update drivers, done.

we all know all it takes is 3 easy commands to unlock bootlaoder

adb reboot bootloader

fastboot oem unlock

fastboot reboot

but in my case i always stuck at 2nd command. waiting for device is shown and nothing happens.

then i ran command, adb devices>> it shows

List of devices attached

adb server is out of date. killing...

* daemon started successfully *

LGH9182bfc6bdc device

next i put the command, fastboot devices and nothing is shown i just go to the next line... c:\adb>

so this is for sure that my device is not connected to the fastboot.

now my only question is, can this device bootloader unlock or not ? so that i stop pushing my limits.

any help will be appreciated.

regards.
