Long story short: My Verizon G2 appears to not have a ROM on it. I tried flashing a custom ROM, that didn't work, had to troubleshoot. During troubleshooting, I wiped everything in TWRP, which, looking back on it was probably a mistake (I'm new at this). The phone still didn't boot right so I went into download mode and used LG Flash Tool to flash the stock ROM to the phone. Something went wrong and now I can't get into download mode, and it appears that TWRP was wiped from the phone because I can only do a factory reset, which doesn't do anything. No matter what I do, I'm still stuck at the LG logo. Is there any hope for me?

Thanks, but both those methods require getting into download mode, which I cannot do. Should I send it in through verizon, or send it to LG directly? It still says rooted when I try to do a hard reset, so do you think they'll still fix it?
first i wanna say that this is my first time trying this and after a lot of research i thought i knew what i was getting into but now i feel completely lost. earlier today I rooted my phone using one click root then installed twrp using auto rec. auto rec seemed to work fine and i clicked open in recovery just to see if it worked. twrp opened no problem but when i went to boot the system back up i started getting security error messages under the LG logo. i tried getting it to boot again after formatting and now its just stuck on the LG logo and not doing anything at all. im almost positive i have a d800 version and pretty sure that i used the right autorec file. i was running 5.0.2 instead of kit kat so not sure if that had something to do with it. please help me out anyway you can, i really need to get my phone working again for work and not sure what to do. i tried searching for an answer but had trouble figuring out what to do.
Yes definetely it has something to do with it. Because autorec uses kitkat kernel. You just have to flash lollipop kernel and you're good to go.

Flash stock firmware with KDZ (Lg Flash Tool) there are a lot of tutorials here on xda.
Good luck.
I'm in the middle of the TOT method right now to get it back to stock firmware, seems to be working. so now if i want to start over and root/get twrp on my phone any suggestions on the best method? i've read a lot of different ways to do it and not quite sure what would be best. sorry if this seems like an easy find, i just dont want to run into this mess again ha.
Lg g2 wont turn on after installing autorec
I have tried to install auto rec on my g2(4.4.2). And now the wont boot and not even going to download mode. When i connected the phone to the computer phone is not getting detected. In the device manager it is shown as android phone=> android bootloader interface. when i try to turnon the phone, the screen just displays some vertical and horizontal lines on left side of the screen. Please help !!!
I have rooted many phones before without an issue, and during the root process for this phone, everything was going great, I flashed SuperSU zip in TWRP and rebooted, since it was the first boot I expected a decently long wait, after about 25 minutes I followed the guide's instructions for Verizon since it did say some Verizon users were experiencing long first boot times. I took the battery out like it said, put it back in, then proceeded to fastboot boot2.img, like the guide said. After letting it sit for an hour this time, I got the idea that something was obviously wrong. After multiple attempts with no success I tried to fix it myself. So far I have learned that on the fastboot screen it says my bootloader is locked again, even after unlocking it. I have tried flashing TWRP as a recovery, just to at least have a recovery boot, that does not work either unfortunately. So as of right now, all I have is a v20 that has no OS, a locked bootloader, no way of booting recovery, I can fastboot with no ADB, and its virtually a paperweight. If anyone has a solution to at least get back to Stock, I would greatly appreciate it! Thanks!
First off. It will say: Bootloader Unlocked: No
Thats normal. 2nd. you are not bricked. You have TWRP installed. You just need to redo some steps.
PM me. and I will help you.
Did you get it fixed?

In his case we needed to redo from step 3.
I managed to un-brick mines after returning sadly from the Sprint store.
First, get to the boot loader screen and try running thru the steps again, especially step 3. You need to make sure you have TWRP.
Use this link to make sure you can get into the different modes (Download mode, fastboot, etc) http://www.hardreset.info/devices/lg/lg-v20/
Once you can get TWRP to show up,then you are good. In the mean time I downloaded "LS997-deODEXd-signed"
When I got into TWRP, I transferred the file to my phone. Rebooted from TWRP back into TWRP and flashed the ROM.
During my reboots, I do get a message saying my phone is corrupt, blah blahblah, but I just wait a few seconds and it will boot up.
Hope this helps.
I had managed to brick mines only 3 hours after upgrading from my Note 4. It took me from 9pm to almost 2am to get it back up again. I can live with the message about my phone being unbootable until someone comes up with a work thru.
Bricked T-Mobile v20
I have rooted many phones before without an issue, and during the root process for this phone, everything was going great, I flashed SuperSU zip in TWRP and rebooted, since it was flash a new rom on it then i get boot loop with TWRP. so i decide to OEM LOCK again after that everything was stuck on my phone just boot loop with LG so any solutions please help me...... THx u for help me.
Kinda nerve wrecking to read about all these "bricked" phones popping up after trying this method lol.. Perhaps I'll just wait until a more tried and true way comes out...
Dirty Santa root is not for the average user who has a couple of experience in rooting.
You have to at least have background on Hard bricking phones to fully understand what you are getting yourself into
For anyone that isnt on sprint that has "bricked" their phone. There are kdz's that will allow you to reflash back to 'stock". Someone had an issue with the kdz, but it was an easy fix. If you failed the process, it can be restored. Just if it doesnt want to boot, just lock and unlock the bootloader...
If your phone doesnt have a kdz, I know TeamDev is working on a custom kdz for such phones. Don't bug him if it isn't finished as I type this.
Anyone that can't get into TWRP, or has failed the process. Either start back at step 3, or if you have TWRP installed but can't get to it, the manual way to get into TWRP is a pain.
Keep your back cover off and hold the volume down button for ease. Now press the power button and as soon as you see an LG logo, let go and repress the power button. Its tricky.... If you get the corrupted screen, pop your battery out and put it back in quick and repress volume down and power. Usually if Im quick enough the first LG logo will hang a lot longer than usual and that gives me time to enter TWRP. A factory reset screen will pop up. Hit Yes twice.
Please help urgent

What does that mean? Not for the average user who has a couple of experiences in rooting.
I've only rooted 2 phones, this is my 3rd (maybe 4th). I am on Sprint. Instructions worked fine for me. I did have one hiccup, but it was my fault, and I was able to root just fine. I've been running for a few months now.
I have not flashed any custom ROM yet, I'm going to wait for the next major version of Android to come out. The only mods I've done so far are Titanium Backup install so I can remove Sprint crap.

it means dirty santa root got a high posibility rate of bricking a device compared to other root methods for other devices and if you have no experience in bricking phones before then you're screwed if it happens to you
Actually, if you follow the directions, almost none of the problems create a true brick-- which means unrecoverable. For most of the cases, you might get a soft brick, meaning you have to back out, use a KDZ to repair it or reflash something else, or start over from scratch and try again-- but usually (maybe with some help from here) you can pull the phone back into a usable state.
I would hazard to guess for the vast majority the process works fine, maybe with a hiccup, but I've not seen many reports of a truly unrecoverable brick from this method. It's complicated, yes, and you need to be ready to read a LOT to understand what's going on, but it seems pretty difficult to end up with a $700 paperweight with this.
So i have been trying tonroot my sprint lg v20 and everytime i try and go to the phone on mobile terminal to enter id
Then enter the apply patch /system/bin/atd /storage/emulated/0/dirtysanta i get this message and i cant go to step 2 to boot into recovery
Any help would be appreciated: i have a sprint v20 and i wanted to know if i have to flash the stock sprint rom or can i just flash lineage rom following this guide? I have it running on AT&T and i want to keep it on AT&T...
can you please assist
Could you help out, please? I don't believe I have hard bricked my LG V20 H910. However, I have read and tried all of the unbrick info out. It seems my screw up is unique. I completed dirty Santa then went to flash a custom. in the boot between that. I get a black screen and cant do anything even download mode will not come up. My PC does make its usual noises when i connect or disconnect, but my phone does nothing.
Ok, I managed to brick mine too. It's a VS995, it was running stock 1AC. I used the LGUP tool to downgrade it to VS99512A, and then did Dirty Sanata and TWRP. After booting into TWRP I decided to try lineage OS with Android 8.0, I did not make a backup of the Stock ROM, which was very stupid. Lineage OS 15.1 flashed but I had no cell service so I panicked and instead of wiping it in TWRP and using the backup of stock I should have created, I just opened LGUP and tried to downgrade it back to stock VSS99512A. Well LGUP said it worked, but when it went to boot it would hang at the Verizon logo with 4 pastel dots. Device manager could see an ADB device and I could connect to it with ADB. So I did and read the logcat. I could see it was trying to update as part of the rollback, but it appeared that some components from Android 8x could not be "upgraded" to Andoird 7.x. There was a repeated error about failing to update SQLite instance version from 3 to 1.
The one feature that could fix this is if the refurbish function worked with any of the VS995 KDZ files we all have access to. But alas, none work instead we only get the upgrade function... or so I thought. Somewhere in my search for the past 2 weeks I found a modified LGUP https://forum.xda-developers.com/v20/how-to/guide-patch-lgup-to-unlock-features-t3652222
**Please be warned what I did was absolutely ****ing stupid, and it was sheer luck I didn't screw anything up.**
From what I can tell if you only flash ("LGUP Upgrade") the KDZ from the same model it never clears the partition it just adds to it. My problem was there was stuff from lineage OS 15 stuck on one of the partitions that was making the rollback to stock fail because it kept saying it couldn't update the SQLLite DB from 3 to 1. So no "upgrade" within LGUP would work because the upgrade function does not clear internal storage. But the link above is to a version someone modded so you can force a partition update from any KDZ onto the system. So I started playing around with forcing KDZs from other models onto my VS995, and I noticed when using the Partion DL function with non-VS995 KDZ files it would say something about the partition changing. All I can assume is that the partition layout is so different on each model and it forces LGUP to re-partition the storage.
**Again I state for the record this was stupid, and I'm only fortunate it worked.**
I forced Partion DL of H91510d_00_VTR_CA_OP_1110.kdz, then H990N10b_00_OPEN_HK_DS_OP_1017.kdz, then back to VS99512A_06_1114_ARB00.kdz, then when it booted it gave the Verizon hello, and moved on finally but the setting service kept crashing while it was trying to load the Secure Boot screen. So I yanked the battery and went into the boot menu and did the Factory Reset function, and it worked.
Lesson learned, always make a backup and don't be so hasty to use tools that aren't fully functional (LGUP).
Perhaps what I've done may help others, maybe I've found out how to reimage or unbrick our V20s. Or maybe I just got really stupid lucky.
Hey guys so i was on stock lg v20 software and i recently rooted and didnt realize that i would loose wifi calling... I tried to do a factory reset but that was a mistake... ATM i currently can get into bootloader mode and fastboot but i am not able to do anything else but that... For some reason when i mount on bootloader the internal storage doesnt even show up... Im not sure what to do at this point I dont think i can just reset back to stock because there isnt no firmware... I know there is a krz file that i downloaded i used to the flasher software but it didnt do anything for some reason i put my phone into download mode and it would be stuck at 0 percent... I was on the h910 model but now its saying us966 for some reason. I can also note that i tried to install the deox rom or whatever it is and it would say it was installed but when i reboot to system it just goes back into fastboot can anyone help me with this? I realized i screwed up but is there anything i can do? I can contact att and get a replacement but i dont know if they will do it since the bootloader is on there.

Umm try getting back into Recovery if you've already flashed TWRP. Pull battery out, hold down POWER and VOL DOWN at the same time, the second that the LG logo pops up, let go of power and hold it back down again really quick. If you do it right, you will get a factory reset screen. Say yes to both screens. If you are unsure that you have TWRP flashed, reflash TWRP from fastboot. If you are able to get to TWRP, do a clean wipe [(dalvik, boot,system, cache) + (format data)] then flash your desired rom.
I don't know anything about going back to stock, especially since I'm on the Sprint variant. Good luck.

I had the similar problem, Im on the sprint variant. If you can access the boot loader. Run Step 3 of the dirty Santa method. this will install the TWRP recovery again, if somehow it is corrupt. After that, download the stock from for your h910 model and place it on an SD card. Flash it and see if that fixes it.
At least with this you will know that it is most likely a firmware issue.
Note: if after you install TWRP and it just hangs on the LG logo, at some given point, you can run the command via your respected operating system.
adb reboot recovery
and that should kick you into TWRP.
This is not an answer to your question, but you should not lose wifi calling from just rooting. Stock based ROMs should also have wifi calling working.
well dang for some reason my wifi calling wasnt working and ik for a fact that the fm radio wasnt working also not that i need it anyways. Well what i did was call att and thank god there sending me a replacement so im going to send this one back when i get the new one i would like to root the new phone but I do not want to lose wifi calling if i do it again i doubt ill be able to get another replacement lol. Is there a easier way to root possibly? And I cant download a stock firmware because i basically cant find one for my phone I have no way to go back to stock so a rom is only option Im going to try this one more time just to check it im going to download a rom for my phone and ill check it

I have a bricked LG G2 that is stuck in a boot loop.
I was running a custom rom and lent the phone to my ex-gf and she tried said yes to OTA update. Then instead of telling me she attempted the fix the phone herself and in doing so used TWRP to wipe backups/all data/everything.
I can get into TWRP. I can use adb sideload.
That is it. No recovery mode, No download mode.
Can't get device detected by qhsusb_bulk
I think I need to fix the stock firmware/image. LG flashtool doesn't work and I think that is because I cannot boot the phone into android and because I can't get into Download mode.
Here is a semi-revelant thread on XDA, I posted there but haven't had a lot of replies, I doubt many people check the G2 forums as its an old phone at this point, yet its still in perfect condition, has a 1080p screen and runs fast.

D803
I was running a custom rom. I *think* it was lollipop.
Basically the phone sat in my desk for two years without use as I had a work from home job and could get by with a free app on my iPad, I lent it to my ex and this happened a few days later
I now need a mobile phone for a new job I am starting and this phone is still beautiful I would really like to use this instead of dishing out multiple hundreds of dollars
Not a problem to help. I've bricked my old G2/my wife's G2 not less than 10 times, and all gonna Ok later. If you has TWRP saved backups - then I can help unbrick it even if it stuck on "LG" logo! Can PM me foor details
As long as EFS is not wiped or you have a backup you can just flash a new ROM with TWRP right? Or flash a backup?
As long as you can access TWRP you can also connect to USB in case you do not have any ROMS stored on the phone and transfer them that way.
