Can't get past TWRP - LG V20 Questions & Answers

Phone was working fine yesterday. Went to sleep and woke up to the phone booted into recovery. Now I can't get it to reboot past recovery. Anyone know why this happened or how to fix it?
Thanks in advance.

Check and see if system is mounted. Also are you sure that it didn't attempt an update last night?

The EXACT same thing happened to me this morning! Unfortunately I had to get to class before I could figure out how to fix it. When I get back home tonight I will try to get my phone to boot like normal and will tell you how I did it.

I have no way of knowing if it attempted an update last night. I was asleep. I tried restoring a nandroid backup from 8 days ago and it still won't boot past TWRP.
Help please! I'm at the Cleveland Clinic with my wife and just found out that my grandmother died today and have to drive back to Michigan tonight. I need a phone and Waze!

I'm sorry to hear, but glad I'm not alone in this. Hopefully we can figure something out.

Sorry about your lose. But click mount and see if system is checked. That's what happened to me before. Making sure system was checked let me boot back up.
If that doesn't work plug your phone into your comp if possible and check to make sure you still have everything on your phone. Another time I had accidently wiped everything and only way to get back up was using the kdz

I checked system under mount, rebooted and still won't go past TWRP.

Have you tried power on and volume down to go through the factory reset screens.
A bunch of us had this problem and it was because an update downloaded on it's own and the bootloader snoops it out and forces recovery to boot.
Just do the volume down + power button - as soon as you see the lg logo release power only then immediately re-press power and continue holding power and volume down until the factory reset screen pops up. Select yes and yes, (don't worry - if you have twrp recovery it can't reset). It will boot you into TWRP and I'm pretty sure it will delete the update files in fota folder.
In TWRP select reboot - system and it should boot normally like nothing happened.

Dude, I love you. I'm back! Just in time for my 3 hour drive home!

if this dosnt work
use twrp file manager to go find the fota and mis folders,
or boot into fastboot and send these comands
fastboot erase misc
fastboot erase fota
data/mis
data/fota
something like this is its path.
data/etc/misc
data/etc/fota
this 2 spots have the update commands that cause twrp loop.
i have a help post in my rom with full walkthrough.

Bootloop into TWRP recovery
Thank you so much, I too was having a panic attack after I flashed a custom rom and it some how altered this and put me in a boot loop into TWRP. I had a couple of questions in regards to ROMS that have native tethering enabled. 1. Is there one that allows Native tethering enabled for sprint? and 2. Is there one that you can update the PRL and profile settings and also one that does use an APN that has DNS issues and a proxy that blocks certain sites? currently I downloaded the ROM that is on the Dirty Santa site its called LS997-deODEXd-signed and it has a hidden proxy that blocks DNS from certain sites also you cannot update.

Download one of my 11 roms ive currently put out.
they all work 100% as far as dns stuff
for tether you need to add the "dun" to your apns. There isnt currently a built in mod.
as well as using shortcut master to add the "dun" to your apns also gets you to where you can change them
prl and profile updates work also as well as fm radio, wifi calling, fingerprint, comfort view etc.

I had to do this again today. This is not good. How can we stop this? I rely on my phone as an alarm clock and this could really screw me if it happens again at night.

Have you frozen or disabled the apps that look for updates?
Supposedly this is what causes it. The bootloader looks for update files in the folders where updates are downloaded and if it finds a file there it reboots recovery.
You have to remove those files, ( I think it automatically deletes them if you go through the factory reset process with the volume down, power button sequence).
And you have to freeze or disable the update apps.

These are the apps I froze. The 3 near the bottom that are blue.

i did this https://forum.xda-developers.com/v20/help/lg-v20-access-to-fastboot-t3557328

Most bootloops are caused by an update file residing on the internal memory. It is not necessary to do all of the stuff in that post. You just need to do the volume down / power button trick to go through the 2 factory reset screens.

[Help needed] Phone will not boot after getting pop-up message

Update: *SOLVED*
I got a strange message that popped up on my phone this morning. It stated "It's gonna rain. Take a umbrella with you". It stayed on top everything else and wouldn't go away. I thought that it could possibly be one of my weather apps and got stuck, so I rebooted. After that point, it gets to the Google loading screen animation and never passes. After subsequent reboots, it does the same thing. I am able to get into TWRP recovery though.
Does anyone know what be causing this and/or how to remedy it? Might it be some type of malware? I have attached a screenshot of it.

Thanks for the link! I do have GO Weather installed, and I have no issue with getting rid of it. Although, I'm unsure how to do that since I can't boot. Any recommendations?

well, since you can boot in twrp you can do a factory reset.
safe mode is a better idea but i dont think you can boot into safe mode without starting the phone.
here are the steps but i dont think it will work so try to delete dalvik and cache from recovery, if that didnt work I think factory reset is the only option unless someone has a better idea
Make sure your device's screen is on, then press & hold the Power button.
In the box that opens, touch & hold Power off.
You’ll see a “Reboot to safe mode” box. Touch OK.
Your device will start up in safe mode. Try using your device normally. Remember, you won’t be able to use any installed apps

I tried clearing the cache and dalvik earlier, along with deleting the GO Weather app files, but that didn't help. I thought about safe mode, but I don't see a way to do it without already being booted to Android.
What if I dirty flash the same stock 6.0 ROM I'm using? I'd like to keep files and apps intact, so I'd prefer to not perform a factory reset, but will if I exhaust other options.
I just realized that I never came back here to update on what happened. I wound up booting into TWRP recovery, connecting to my PC via USB, backing up any data that I needed, then factory reset. That took care of it. Luckily, that also cleared up some other minor, but annoying, issues I was having. Needless to say, I haven't been and won't be using GO Weather EX any longer.

Help! Stuck in TWRP recovery

Hi Guys,
Long story short, I got the root to work at first, but I was having issues with PlayStore as I couldn't install most of the apps. Then I tried wipe data and restored TWRP backup which didn't fix the problem and lost SuperSU. I tried to reflash SuperSU and failed. Lastly, I did a factory reset via the OS's settings menu and my phone would never boot into System again. I tried using LGUP tool to flash the TOT tool, but it doesn't find my device. My phone is now officially softbricked. Any help is appreciated. I will donate if that is needed
Thanks

I haven't run into this on my V20, but a couple times on my V10 when i'd softbricked my device and couldn't seem to revive it (even with ToT or KDZ files on LGUP) i was able to recover with LG bridge. Basically you go to the third tab titled "software update" but instead of selecting software update, select the "update error recovery" link at the bottom right. It takes awhile but i think it downloads and restores files (or maybe partitions) that other recovery methods don't. Give it a try and let us know if it worked.

Yeah windows sees it as a Portable Device (Attached), I can transfer files to it.
This is very similar to what happened to me, I couldn't get into TWRP though.
I could not find a resolution then and still havent, but I did return my phone for a new one.

I guess I can only wait for a custom ROM now
I'm having the same issue. I've tried every step here. I've flashed multiple ROMS, just hoping one would boot and every one keeps booting right back into TWRP after showing the "your device software cannot be checked for corruption...".
PLEASE HELP! LOL...not sure what else to do. I'm, using the latest version of TWRP and I can get into bootloader.
Tried running the "EasyRecowvery.cmd" and it loads fine. I go into twrp and do the format data and then attempt to run any of the options and I get a "This Device doesn't look like a T-Mobile V20. Proceed anyway? I stop and can't get anything. But when it initially ran it said SUCCESS when locating adb .exe and found the device as well omni_h918.
No matter what it continues to go into TWRP. ANY ANY ANY additional help would be great. I want to return this device to T-Mobile before my 14 days is up. Please help out if you can.

I had this issue on my Verizon variant the other day and I tried everything I could think of. I flashed roms, restored backups, redid the dirtysanta method several times, flashed the boot images in fastboot, and nothing worked. What finally did work (can't make any promises but this worked for me): steps below
*restore your full stock backup (if you have one)
*after the backup is restored, in TWRP, go to mount, and mount the system. Check the box and press the mount USB storage button
*power off device
*use the button combo to boot into TWRP. It's volume down + power, as soon as you see the LG logo let go of power for a breif moment and press and hold it until a white screen comes up. Choose yes for the next two options. This will bring you back into TWRP.
*now go back to mount and check system, and press the mount button, and reboot system.
This got me out of TWRP and booting normally. I haven't had an issue since.

You, sir, are a lifesaver. I jumped through all the same hoops as you and was actually starting to panic a little, as the last time I got into a similar string of unsuccessful fixes, I managed to hard brick my Note 2. This worked like a charm on my Verizon variant (the backup part was seemingly unnecessary, as my backup was toast by this point). You definitely have my thanks!

Awesome. I was getting a little worried myself when I was stuck in TWRP because I was trying everything I could think of.
I didn't think the backup part was necessary but it's one of those things where you mention everything you did just in case.

I had some trouble following this at first but it indeed worked.
My v20 was stuck in TWRP (3.0.2-1) after forgetfully hitting OK on the System Update, it was running H91810q and was previously rooted.
I first backed up my phone in TWRP to my SD card and then copied that to my laptop.
In TWRP: Mount > System, I have 3 buttons on the bottom: 'Mount USB Storage', 'Select Storage', and 'Disable MTP'. If I choose 'Mount USB Storage' it goes to the next screen and the only button is Unmount. I cannot get it to shutdown without pulling the battery.
What is missing here is to press Unmount go back to the main TWRP menu, then Reboot > Power Off.
I held Power+VolumeDown, released Power while still holding volume down and I got the white Factory data reset screen. I choose Yes on the next two options to perform the factory reset.
Then it restarted and went back into TWRP. I choose Mount, selected System, pressed Mount USB Storage, then Unmount, Reboot, System.
It booted and took a while since I also flashed the H91810t rom to do an upgrade at the same time from here:
https://forum.xda-developers.com/v20/development/rom-h91810q-stock-rom-twrp-flashable-zip-t3681312
Interesting all my apps, and settings were still on the phone.

Glad you got it working. As far as the issue with the instructions that could be down to a change in the newer versions of TWRP. I posted this 16 months ago and many new versions of TWRP have come out since. I remember trying to be extremely accurate in my instructions but it is possible I screwed up. Been too long ago and I can't remember now.

[REQUEST] US996 (Unlocked, not USC variant) stock recovery image or full firmware

I was in a similar position to where it would just always boot into recovery forever. I tried doing several restores from stock and other backups. Different ROMs and even went through dirtysanta again. Nothing worked.
What wound up working was me getting into the device's factory restore screen (not TWRP's). I believe you get there by turning on the device while holding the Vol down + power button, when the LG screen comes up - let go of the power button for like 1-2 seconds and then press/hold it again. It should be a white screen that's asking if you want to do the factory screen or not. Just do that. It did its thing - then went to the LG screen again. I was a bit impatient and only waited like 2 mins. It didn't go anywhere (you could probably wait longer or so) but I just simply took out the battery and then put it back in.
It did wind up booting to the system again after awhile.
Just letting you know what I did after I messed up with a certain thing in a hidden menu.

Accidentally installed OTA update, now seeing many problems and can't find a fix

Yesterday I accidentally installed the OTA update. I got stuck in TWRP and flashed a new ROM. Phone booted up fine, but now I have no cellular signal, nothing that uses video or sound works. Camera doesn't work, flashlight doesn't work.
I tried several different ROMS and nothing changes. Even the system sounds, ringtones and so on do not work. Anyone have any idea what I can do? Thanks
boot into fastboot
fastboot erase system
fastboot erase cache
fastboot erase userdata
fastboot erase misc
fastboot erase fota
fastboot erase boot
then pull battery and reboot into twrp by holding power and vol down, when lg logo appears then click the power button and re-hold it down to get into twrp.
once in twrp, check and see if system is mounted, if it wont let you mount, go to wipe and wipe everything (not ur sd of course)
System, cache, dalvik, data, internal, everything... the fastboot should have already done this but let twrp do it too..
once done, use the format option and format data also, some of these may error thats okay, just keep going..
once done reflash the full rom that matches your device.. let it flash and reboot and do its thing. this should fix the issues...
once it boots you may need to let it activate, or re-activate.
Only other suggestion would be if you have a twrp backup and you backed up your efs, its time to restore it also and see if the NV files have been damaged.
I've tried installing several different roms available on xda but that didn't resolve the issue. My phone remains in a boot loop state. Is there a way I can return to stock without compromising my ability to use the current root exploits?
Might help to know what you've got currently, are you able to get to recovery at all, etc?
I could get into TWRP with no problem, I could flash any rom, but all would give me the same issues, no sounds, no flashlight, no cell signal. I think the OTA update messed something up. I ended up putting the phone back to stock, locking the bootloader and exchanging the phone for a new one. I got my new one today, it's on 10d, just tried to root it the same way as the last time and it keeps failing. I get the same problem as the guy on this thread https://forum.xda-developers.com/v20/development/helpt-easyrecowvery-t3543873
My Solution
[MY FIX]
this post contains my working solution to the problem.
my problem is...
I accidentally clicked on 'install OTA update' on a rooted lg v20 t-mobile. A second after clicking it I realized that was the wrong button to press. AND so the start of the endless TWRP boot loop that allowed me to access TWRP to perform multiple tasks but couldn't boot back into my system UI where I can make phone calls.
I had this problem and spent days trying to figure how to get it back.
my solution is...
I tried everything to delete the *fota* and *misc* folders with fastboot; however none of the methods worked, until I tried the methods suggested in step#1 in "Stuck in a endless boot loop to twrp " in https://forum.xda-developers.com/v20/development/rom-ls997-stock-debloated-su-goodies-t3531923.
So after deleting *fota* and *misc*, I had to exit the bootloop by 'reset all data option' by pressing YES twice. You read that right, you will have to agree to reset all user data by clicking YES twice. THO the effect will NOT reset all your data; it will just kick you out of TWRP recovery mode. I was pleasantly surprised to still have my data.
https://www.youtube.com/watch?v=tDq0qMbgjL4 That video shows as proof that it doesn't break things and also how to get into TWRP. You can also use the same methods to get out of TWRP.
Here's the text version:
1. hold volume down and power.
2. when lg logo shows up click power and re hold it while still holding vol down.
3. if you do it right in about 4 seconds or so it will boot to a menu, choose yes both times and you'll be back in (or out of) twrp. (yes you read that right!, don't worry you wont lose your data)
Hope this works for you as it did for me. I'm only posting because I didn't find a comprehensive solution post.

This fixed my issue. Thank you so much!
For further clarification, I had to delete all these folders that existed (I didn't have them all) using TWRP file manager. Make sure system is mounted. :
/fota
/misc
/data/fota
/cache/fota
/data/misc
/etc/fota
/system/etc/fota
Powered off after that, and then I manually booted into TWRP using the buttons method and hit reboot system and all was fixed.

This isn't working for me. Keeps rebooting to TWRP.
I get FAILED (remote: unknown command) with every adb command
Any ideas?

Don't use Easy Recowvery. Do it manually from the original thread. You can also google it for some sites that have cleaned the instructions up for easier reading.
I just did a H918 10d like this.

Changed a permission now I am stuck in endless reboot

Not sure I am posting in the right spot, but pretty sure the people that can answer are in this section.
After putting it off for months, I upgraded my 6T T Mobile converted to international to OOS 10.3.3 with the ElemetalX kernel, and xxxNoLimits 10.2. Did this several days ago, no problems. Great battery, smooth performance. Even getting 2 days with my VPN on and mock location set to "always".
I went into app ops and noticed almost every app now has "access location from media" and started going through and denying that permission for almost, if not all, the apps. I remember a couple of system apps I did that to. Google play framework being one of them, and, I think, google play services. There may have been 1 or 2 more system apps I did this with also.
I do not have a google account on my phone. I don't want to make it any easier for my pocket tracking device to track me than I have to.
I added an open source mock location app a day or so ago, not problems.
About 5 or so minutes after finishing up in app opps, I went to get the kiddo some food and looked down and noticed my phone rebooting. Now, it is in an endless boot loop.
I can hold power + up volume and get it to power down, but can't get back into TWRP recovery. Figured a quick reflash puts me back to zero and I can start over.....more carefully....but the phone is not cooperating.
I should be able to use adb and flash TWRP that way and use adb to reboot to recovery ( going to have to brush up on the how to before I start though.).
Any thoughts as to WHAT I have done and WHY I am now stuck on endless boot( w XXX animation )??
Is there an easy fix I am overlooking?
Thanks in advance,
JC
Volume Up + Power while turning on will boot to fastboot.
Volume Down + Power while turn on will boot to recovery.
Holding Volume Up + Power should force the phone to turn off.
Volume Up + Volume Down should put your phone in Download mode for the MSM Tool
Can you get into fastboot? Then you might be able to boot TWRP again temporarily?
Thanks, that gets my into TWRP, unfortunately, my dumb ass deleted the last OTA update after I flashed it. Should be able to side load it onto the phone, then flash it via TWRP.
Well, things just took a turn for the worse. I forgot to flash twrp after sideloading the os. Now it is keeps booting into Oneplus recovery. Still shows bootloader is unlocked though. I have done everything except a total wipe. Maybe I can still get TWRP back........

Flash twrp recovery via adb commands, you'll find tutorials on several XDA forums or YouTube
