"Erasing" Loop - Tried Returning to Stock After Converting to US998 from H933 - LG V30 Questions & Answers

"Erasing" Loop - Tried Returning to Stock After Converting to US998 from H933
I rooted my phone using LGUP and tried to switch back to stock; hoping to keep root. I flashed all items except "recovery" but then tried to re-flash just the stock recovery, as stated in on one of the posts I found, and now I think I have a paper weight. I made sure to read the instructions a few times before doing things, but guess I missed something, or the instructions I followed aren't for my version or may be outdated?!
I can't get into download mode. The PC doesn't recognize I've even plugged it in. And now it just keeps boot looping showing the Erasing Circle over and over and over.
Anyone here know if I have any hope that once the battery dies, I could plug it in, holding the volume up, and be able to get into download mode? I'm hoping I can... Not a happy camper right now.

I see the thread title now. Let me respond in a few minutes.

You didn't root your phone with LGUP. You rooted your phone with TWRP and Magisk. You used LGUP to convert to US998 so you would have fastboot flash commands to unlock bootloader and install TWRP, so you could then root with Magisk.
Why don't you ask in thread where you were following the directions? Yes, it is tedious and complicated for the H933 -- but the end result is you WANT TWRP custom recovery and Magisk, but you want to eradicate all traces of US998 firmware.

I still don't have any answer to my question though...

I appreciate you taking the time to reply. You are correct in saying I didn't root with LGUP. I mistyped/misspoke. There are so many threads that I read, I can't find the one I was following. I had 15 tabs opened; I freaked out, and so I created a new thread for my problem. My problem doesn't really involve any particular thread now because it's not even booting up - in order for me to do anything.
I see the LG logo.. then sometimes I see the stupid bootloader warning, then back to LG logo for a few seconds and then it says "Erasing" in bold vibrant colouring.. then it shades out barely visible for 10-15 secs. Turns off, then basically repeats.
I know about all the flashable zips for H933.... but ALL of them say NOT to use them to convert back from US998 to H933.
Here is a thread (step 5) which basically everyone else posts also, that says you flash the kdz - everything except recovery - and twrp should be installed. This is not true. I did this about 6 times and could never boot into recovery afterwards. It would erase the phone and go back into setup mode each and every time.
I couldn't find any article to explain how to get back to stock firmware without using the kdz, which I did, and unselecting recovery. When doing so, twrp was gone - despite me not selecting recovery or even recovery.bak sometimes. So what I did was, use LGUP again with the kdz and uncheck everything except recovery and recovery.bak the 2nd time around and bam... now I am stuck.

Who said you couldn't use H933 after US998? You're fine if you use partition DL.
I have gone from US998 to H933 several times.
I'm currently on my commute to work but let me read your issues and see if we can't get you back to normal.
( I'm pretty active in modding our H933 )
Don't touch recovery.bak; only deselect recovery.
So where are you currently?
And after you pull your phone from PC after not selecting recovery are you pulling your phone and trying to master reset to access recovery or letting LGUP auto boot into twrp? Should happen as soon as H933 attempts to boot.

Have you tried Master Reset to stop the boot looping? Master Reset is not factory reset.
Master Reset -- using buttons:
1. Unplug phone and turn it OFF.
2. Press and hold the Power and Volume down buttons.
3. When the LG logo appears, quickly release the Power button only -- then immediately press Power button again, while STILL pressing the Volume down button until you see the screen to select Yes to erase and reset everything.
4. Release both buttons so you can make your choices.
With your device powered off, press and hold the Power button and Volume Down buttons simultaneously for a few seconds.
When the LG logo appears, quickly release and then re-hold the Power button while keep holding the Volume Down button.
Let go of the buttons when the onscreen menu appears.
When you see the option to Delete all user data (including LG and carrier apps) and reset all settings message prompt, press the Volume Down button to highlight Yes.
Then press the Power button to reset the device.
Wait until the reset is complete then reboot your device. If it’s able to boot up successfully, proceed with the initial setup.

You can even do it if you can not power the device off, but you just have to time it right.
This is the most complete guide of what you were probably trying to do, if trying to go back to stock and keep root:

@christopherrrg wrote a "little guide" for the peoples, who may ever have thought about going back to h33 original (rooted or not) sw. Give him some thanks pls, he's now a few nerves lost in this procedure i can imagine :good: thanks!
Here it is:
Okay so the steps below are for AFTER using the WTF thread to convert device and unlock bootloader; these steps are for canadian model users who would prefer to go back to stock canadian kdz with working root and twrp intact.
Step 1 - Attach converted US998 (bl unlocked and twrp installed) to LGUP.
Step 2 - PARTITION DL the canadian kdz but do not include recovery.
Step 3 - Let phone boot right from kdz flash and it will automatically boot TWRP.
Step 4 - While in TWRP; 1st factory reset AND AFTER format data then reboot recovery. (If not done TWRP has mount issues with cache and or system.)
Step 5 - After TWRP is rebooted flash no-verity-opt-encrypt-6.0.zip + lg-rctd-disabler-1.0.zip and afterwards flash magisk.
Step 6 - While still in TWRP use the option to power device down.
Step 7 - Attach device to PC while holding vol+ and it will automatically start download mode.
Step 8 - PARTITION DL the canadian kdz again EXCEPT uncheck everything BUT stock recovery; let it flash and reboot.
Step 9 - Should reboot 3 - 4 times.
Step 10 - Once booted to setup; get past then activate USB debugging, also open magisk and click yes as many times as it asks you. (Magisk remains because only RECOVERY is flashed at this point)
Step 11 - Download TWRP and rename to just twrp then place it in the root directory of your internal storage.
Step 11 - Connect device to android debug bridge, and start a shell with 'adb shell' command.
Step 12 - then type 'su' and hit enter in order to gain root privilege. (Will have to click accept on super user on device)
Step 13 - then type 'dd if=/sdcard/twrp.img of=/dev/block/bootdevice/by-name/recovery'
If done correctly you should see flashing (almost like fastboot) however you will not have anything happen to your device graphically SO open magisk and click modules then click reboot to recovery and profit!
You should be on H933 kdz with TWRP and root.
However for some weird reason, cloud is correct as the battery drain is abysmal. My phone used to go from 9am 100% to about 60% by the time I get home at 5pm. Today it's gone down to 22% from 100% at 9am and it's only 2pm. @cloud1250000's brain was mostly picked for this so he deserves any and all credit; I just confirmed and wrote this up for reference.
Enjoy!

Also; I realize my guide in seadersn posts need a bit of an update so I will message him today and have him update as a ton of people are using it for reference and that guide has battery issues. (Without doing dd etc)
Try following this guide to the letter.
https://forum.xda-developers.com/lg-v30/how-to/canadian-h933-compatibility-h930-roms-t3897586
Just replace the latest with 20i (h933)
Make sure to read my post inclusive at the end of that thread; feel free to PM me as well if you can't get anything the way you want it.

Unfortunately I can't do anything with the phone when I connect to my PC with the USB cable - except when holding power and both Cole buttons, i can get it to load a page with the imei number etc.
I can also (by holding power and toggling both volumes) get it to recognize on my PC, but it shows up at QSLoader 9008 (or something like that - I'm at work right now so can't type exactly what it shows up as - but know 100% it says 9008).
I installed QPST and will see if I can flash it this way, after I figure out a way to create/find the firehouse. I found a YT video showing how to create the files needed so will give it ago when I get home.
I am grateful of the replies. I'm sure you get many idiots like myself who do stupid crap - so thank you for always still wanting to help. It must be annoying but us idiots are truly grateful!!

This sounds like what had happened to me with the RSA after flashing modem.bin. I only got lucky because my TWRP flashed successfully and I was able to restore using seadersn stock method. I've never gone as far as actually putting my device into 9008 brick (yet) so unfortunately I'm not much help there and for that I'm sorry. However there is a gent on ebay who will TeamViewer to your PC and fix it for you. A lot of people report it has a different device firmware but they do report success.
Also don't beat yourself up and call yourself an idiot.
Us humans are curious creatures! While it does suck for your device; it's just a speed bump!

BIG PROBLEM-no Recovery-no DownloadMode-no Fastboot

Hi,
I HAVE GOT A VERY BIG PROBLEM.After i installed the App AutoRec(i had TWRP befoe,but i thougt when i install it it updates TWRP to a newer version) my phone only starts in Fastboot Mode-no DownloadMode-no Recovery Mode.
After that i erased all the things(aboot,boot,cache,system,laf,....) und flashed them again,after that the Phone only starts until the LgLogo then it stops.No Fastboot,no recovery,no DownloadMode.When I Press VolumeUp+PowerOff i get into the Factory Reset.When i press on Erase all user data&restore default settings?---When i press Yes the phone the logo comes an on the left up side stands"Error:boot ceryfication verify
Secure Boot error
Cause :Boot cerification verify
After that the display is black,and i have to restart the Phone.
When i press all 3 buttons on my phone,i got into the hardware key control mode,does me help that everthing?
When i plug in the phone in my pc,it says "unknown device",when i use to do something with fastboot it says"waiting for device"?
Please help me,what can i do?I have the Phone only since 2 two days,an i wouldnt lost it Unhappy
Sorry for my bad english
Can you still get into twrp? With the phone off hold power and vol down til LG logo comes up the release and press again after. Should take you to a menu, just hit yes. If it takes you to recovery just hit factory reset and it'll,take you to twrp. If so, I'd recommend putting a Rom onto an sd and flashing it. You'll lose everything but it's better then losing this beautiful phone

You obviously didnt read his post correctly. He stated that when he gets to the factory reset area which leads you to Recovery Mode/TWRP it shows the LG logo appears and nothing happens.
As for you my friend if you are able to somehow get into download mode with a button combination you have a chance at saving yourself by using a TOT or KDZ file to restore your phone to stock software. But i also have a question for you.........Why the hell would you allow an app to flash a recovery file that has nothing to do with BUMP'D? The Bump'd recovery for our phones is specific to our phones! You should never auto update any recovery unless stated its ok from the Bump'd developers, Which they never did or will because our TWRP Recoveries are different than any other phones because of the bump'd implementations with in them and the boot.img's. Sounds to me like you may have screwed up your partitions and/or boot stack. Your are better going on IRC and requesting the help of TheCubed/IOMonster and AutoPrime, but mark my words you will face some heavy criticism from members of the IRC channel when you explain this story to them. But they are always willing to help.
I dont know why i have done it,im new on Lg.Before i had an HTC there is so many other.I will aks that guys.I hope i can save my new phone.
But the Problem is,i dont get into download Menu,i did everthing

Thanks guys,
I managed to get back my phone. I had to put it on qualcomm 9008 and after that to flash again all files.
Best regards.

soft bricked my phone... desperate for help..

alright guys, so here's the story. just yesterday i bought a brand new lg v10, got it home and the first thing i did was root the device and used ADB to load TWRP following the instructions here on SDA to a T for the ROOT/RECOVERY setup. and it worked. all was fine and dandy, the first time i booted into TWRP via ADB after root i got in, flashed a debloated ROM + xposed and again, everything went fine.. loaded into the OS of the new ROM, went through setup, turned on USB debugging, clicked always allow this computer, installed xposed app yadayadayada. I then, using ADB again, loaded into TWRP. i created a backup there just in case something went wrong with the changes i was about to make and once the backup was complete i loaded back in to the OS. at this point i thought i had done everything right and was confident that if i made system changes that didn't work out i could just flash the phone with TWRP from the backup i made. right? WRONG! ...apparently... so anyways, i made my first change, which was to use a NONROOT app called texdroider or whatever to change my DPI (as i have done with a couple phones previously without much issue) but i didn't take into account that stupid second screen... making the DPI changes system wide, as i'm sure those of you that know this phone are aware, causes the systemUI to crash with an error.. making the OS unusable.. so i tried to load into TWRP by holding the volume down and power button.. but instead it just booted me to the factory recovery.. not TWRP... the phone is unusable within the OS, i can't get the phone to connect to adb to boot into twrp as i had previously, i can't seem to get the phone into download mode, and i can't boot to TWRP and the OS is junk at this point.. but it DOES say on the "LG" screen that the bootloader is unlocked so i'm really hoping i'm not completely out of luck.. but i am not sure what to do at this point. does anyone here know of anything i can try to get into a custom recovery at this point? if i could get into TWRP my SD card in the phone has a backup, the original image, not to mention i could pull the SD card and add anything i need via my pc and then boot back to twrp etc etc and i would have no issue fixing the phone... i really don't understand what i did wrong or why i can't boot to my custom recovery but i'm at a loss.. i'm just looking for a way to force the phone into a custom recovery... or restore the original factory image.. if you have any advice at all i would really appreciate it.
Thanks for reading
**UPDATE** this may or may not make things much easier... but I got download mode working!! so at least there's that, still no custom recovery and i'm currently looking for a KDZ or TOT file to flash via lg flash tool... hopefully that makes things easier..
When you say you got to the factory recovery, what was that, an Android on its side or something asking you to factory reset your device? If it was the factory reset screen, if you select yes and then yes, it will take you to TWRP if you have it installed. If you don't it will factory reset your device.

To boot into recovery from power off, you hold volume down & power. When you see the LG logo release and press power while continuing to hold volume down. Then as said above, it come up as a factory reset, select yes each time, and it should boot into twrp, providing you installed it correctly.

it was a screen asking me to do a factory reset, i click yes, it asks to confirm, i click yes again and then it "successfully" factory resets my phone... it shows the android factory reset symbol that its resetting, then says that its "optimizing apps" and goes through that whole process.. but when it finally loads the "welcome" screen (so i know for a fact that some sort reset has taken place) i get the same "systemui has crashed" error and the OS is unusable and won't connect to my computer.. idk why i can't access TWRP.. i booted to it 3 times before this happened, though never by the hardware buttons on the phone.. everytime i booted to TWRP i had used ADB to boot to TWRP.. what makes me the most sad is that i have a nandroid backup on my SD card... but i can't flash it without recovery.. which i can't install on the phone without getting into the OS..
is there any way to install TWRP or even boot to a temporary TWRP so that i can do so? if i can flash my nandroid i'm saved.. if i can get into a custom recovery i'm saved.. if i can find a .kdz file to flash, i'm saved... if i can get my phone to be recognized by my computer/adb i'm saved.... there simply has to be a way to unbrick this phone...

well i seem to have somehow NOT installed TWRP correctly because it just proceeds to factory reset my phone.. which for some odd reason doesn't reset the DPI... leaving me stranded... is there any way to get ADB to see my device in its present state? my computer makes the device recognition noise when i enter download mode and i can see it in device manager but not my computer or ADB
I've had this phone just over 2 months but I'm not positive, is download mode the same as the bootloader on this device? If so, fastboot commands should work, and you can flash TWRP again, or do 'fastboot boot TWRP_filename' and it will boot TWRP temporarily.
Oh, and the factory reset just wipes your data, but otherwise doesn't restore your system to factory state. That's why your dpi change remained.

dude.. then what good is a factory reset?!? like seriously... and yeah, i tried that but i can't get adb to connect in download mode.. the device doesn't show up when I type "adb devices" like it did when i first rooted it. ... and i thought i followed the instructions exactly as it was laid out from this link.
http://forum.xda-developers.com/tmobile-lg-v10/general/guide-how-to-root-lg-v10-easy-t3274699
i think somewhere in there i must have missed something and ended up only booting into twrp temporarily.. which is certainly possible since i never boot to twrp during that initial process from the hardware keys or soft keys.. always through adb.. the phone was already plugged in.. typing the command was a couple keys away..
is there anyway to get TWRP on to the phone now? or am i screwed :'(
Well, it is a factory restore for the average user, because the average person isn't modifying their system. But no, I'm sure you're not screwed. If you're in the bootloader you can't use adb, you're already past that step, so you can skip to the fastboot part. What happens when you type fastboot devices? If the phone shows up then you can either fastboot flash or boot TWRP..

from what screen should i be attempting this? hold volume up with phone off and plug in to computer to enter download mode? should i try it at the factory reset screen (volume down plus power)? those are the only two screens i seem to have access to.. in download mode my pc/adb just doesn't recognize the phone.. it doesn't show up as a proper device like it did before this whole thing and in that factory reset mode i get nothing.. the download mode seems like its built for LG and runs from different drivers because in device manager it shows up with an error code that it couldn't start the device (this was not the case when i was using adb to unlock the bootloader and then using the bootloader to boot to TWRP..) what am i missing?
and hey, thank you so very much for taking time out of your day to help me. I really do appreciate it.

No problem buddy, and sorry for the confusion. You want to be on the bootloader screen, so here is what you can do: turn the phone off(or remove the battery if you have to, and put it back in), plug the usb cable into the computer only(not phone), hold volume down on phone, plug the usb cable into the phone. That should get you into the bootloader, and then you should be able to fastboot flash or fastboot boot TWRP.
Waiting for a resolution to this thread!
I'm pulling for you from the cheering section. (otherwise known as afraid to do it myself section!)
I'm pretty sure others have come through this exact situation unharmed (I've pretty much read every thread here.) so it's only a matter of time before you get this figured out.
Here's hoping it's sooner than later.
Sorry I can't offer more besides encouragement!

@ngoblirsch Along with the information provided in these suggestions and what you have said, you need to reinstall your LG/fastboot drivers on your PC while in fastboot mode

That should get you into the bootloader, and then you should be able to fastboot flash or fastboot boot TWRP.

OH DEAR GOD THANK YOU!!!!
I spent all damn day yesterday trying to figure out how to get to the bootloader on this phone.. everything i read online said to hold volume down PLUS power while plugging it in and it was NOT working lmao. dude, thank you so much. after i read that comment here it took me about 30 seconds to connect to adb and boot to TWRP. This thread can be listed as RESOLVED!
Thanks again!! can't wait to start tweaking this awesome phone!

I'm pulling for you from the cheering section. (otherwise known as afraid to do it myself section!)
I'm pretty sure others have come through this exact situation unharmed (I've pretty much read every thread here.) so it's only a matter of time before you get this figured out.
Here's hoping it's sooner than later.
Sorry I can't offer more besides encouragement!

Well I appreciate the encouragement, it sure seems to have helped! Issue has been resolved. ended up that i just didn't know the hardware key combination to get to the bootloader/fastboot mode without being already connected to adb. nothing that i could find online said to hold volume down while plugging it in to a computer. as soon as i was able to do so i connected to adb and it was a breeze from there; I am now back with an OS AND a customer recovery properly installed on the device!! I will be hanging around these forums for as long as i have this phone so i'm sure i'll bump into you guys! absolutely love the community here on XDA, you guys are freaking awesome!!

Anyway to force power down v30 stuck on LG logo? (us998)

2 hours later Ive given up, google dosent have the answer, neither does clueless LG support. On my previous phone, note 4, a simple battery pull would have done the trick.
But anyway, it's stuck on the LG logo screen, have power key/ volume down rebooted multiple times, no luck. Someone at LG support said hold the power button down for about 30 seconds and it should power off? Is that right? It didnt work out for me, held it down for over a minute, did that several times. At this point I just need to be able to power the device off so I can boot into stock recovery, but am unable to.
Btw I apparently messed it up by disabling "bloat" through adb fastboot command prompt, I was only maybe 5 apps/ programs in when the phone froze, that's what ultimately brought me here.
Don't have a V30 yet, but the ol' Quark was kind of fidgety, maybe its method will work.
Hold Power+Vol Down until it reboots. Let go of Power, but keep Vol Down held. Hopefully, the boot menu or recovery will come up after some seconds. Should be able to completely power off from there or factory reset.
T-Mobile also describes a specific thing you can try involving some button timing, but I've read that it's not supported on all variants.

Thanks for your reply, I tried that 3 times, no luck though. LG has got to have a way of force powering these things off you would think. In the meantime I'm concerned about screen burn in with that bright white LG logo glowing on screen for hours.

Ok here's the proper timing on that

That worked, but unfotunately after the phone sat with that lg logo on screen for idk maybe 4 hours.
Gross. God forbid they just put in a proper boot menu like most other manufacturers.
On the bright side, if it's suffered any burn-in it should be visible on that bright white factory reset screen.

Fortunately, no, everything is back up and running and looks good. I was certainly worried about i though. But im glad now I know how to do it now, especially since I'll be rooting this device as soon as it hits LG's bootloader unlock list
@breacherman Did you get it to power off from stock recovery? I'm in the same situation. I can get in to stock recovery and even download mode. But I can't get it to boot or power off.
Update: fixed it.
welp looks like I have this same issue on my US998.
I think I may have borked it. The device is stuck on the LG V30 boot screen and I can no longer force reset into TWRP. I also cant get the device to completely power down to get into fastboot mode to try and use the USB cable trick
I cant use uppercut, as the device wont connect to my pc since its stuck on the boot screen. Talk about frustrating. This all happened when I mistakenly installed the OREO TWRP on a nougat based US998. For your own good DONT repeat my mistake.

That's not the cause of your problems. I have the Oreo-compatible TWRP installed on Nougat US998. It's fine. It's also compatible with Nougat.
It's just a newer, better version of TWRP -- 3.2.1. There's no reason not to install it. You just install it within TWRP, using install "Image" to "recovery".

yeah pretty dumb move on my part. I installed a oreo rom, on my US998. Which up till today was all fine and dandy to run OREO roms on the nougat firmware. I decided to try the latest boombox rom, based off 20D. It booted my device into a dual sim version, killing my data connection, while showing that I had two sim slots for some reason. I thought, hmm maybe I need to upgrade TWRP. So I flashed the latest TWRP image IN TWRP (probably the killer switch) and everything seemed ok.
I rebooted TWRP and then wiped, and reinstalled the rom, and it booted up fine, yet still showed my US998 as a dual sim device.
So I figured, hey I am still on the nougat firmware, Ill just go back to stock. So I kdz back to stock (latest version), and then try to install the original TWRP through fastboot, bootloop city.
I am draining the battery, to try and power the device down, and then I will retry the USB cable to fastboot and try to kdz back to stock again.
I should have known better after all the LG devices I have owned, but sometimes you take a loss, messing around with LG lol.
Wish me luck on the battery drain, forced fastboot method.

Did you ever get this fixed? I am stuck on the LG V30 screen as well. I can get into factory reset but nothing else. The last command I used was via adb to boot into twrp when I left twrp and tried to reboot it only showed the bootloader warning screen and now I am stuck on the splash screen.

Press and hold the Power button (or fingerprint scanner) and Volume Down button simultaneously for 8 seconds. Your phone will then vibrate, shut down, and reboot.
This method usually fixes minor software issues transpiring in mobile devices without affecting any data stored on your phone’s internal memory. Basically, it works the same as a soft reset only that you forced the device to reboot through the hardware key combos.
Second method: Connect your LG V30 to a charger and let it charge.
When your phone does nothing and shows nothing but a black display, chances are you would immediately think that it’s damaged. But the truth is, your phone might just have ran out of power completely and therefore no longer able to power up. With that said, try to connect your phone to its charger then allow it to charge for at least 20 to 30 minutes. It can take longer for the charging indicator to show up especially if the battery was totally drained before charging. Also make sure that your phone is able to charge properly. You can try using a different charger for your LG V30 or use other power sources available to ensure that the problem you’re dealing with is not associated with a faulty charger or power outlet.
Third method: Try performing a master reset using the hardware keys.
If your phone is able to charge, try to perform a master reset with the hardware keys. A master reset will restore the original factory settings and wipes out your personal data stored on the internal memory of your phone. All your downloads, ringtones, images, apps, contacts, and Visual Voicemail will be erased in the process. Considering that the problem is triggered by a software bug affecting your LG V30’s system functions, a full system reset will be able to eliminate the bug as well. Here’s how it’s done:
Back up all your data on the internal memory (if possible).
With your device powered off, press and hold the Power button and Volume Down buttons simultaneously for a few seconds.
When the LG logo appears, quickly release and then re-hold the Power button while keep holding the Volume Down button.
Let go of the buttons when the onscreen menu appears.
When you see the option to Delete all user data (including LG and carrier apps) and reset all settings message prompt, press the Volume Down button to highlight Yes.
Then press the Power button to reset the device.
Wait until the reset is complete then reboot your device. If it’s able to boot up successfully, proceed with the initial setup.
Fourth method: Plug your LG V30 in to a computer
LG Bridge is the new PC suite software for LG Android smartphones like LG V30. It works the same way as iTunes does on an iPhone and iPad, when accessing and managing iOS device system.
LG Bridge is mainly used to backup and restore LG phone data, sync data, update software and other related tasks. In order to use this app, you’ll need to download the LG Bridge installer from LG Support site then install it on your computer (Windows or Mac).
After the LG Bridge software is successfully installed on your computer, try to detect or access the LG V30 phone system through LG Bridge with these steps:
Connect your LG V30 to your computer using the USB cable that comes with your device. Alternatively, you may use the cable attached to your LG charger. Be sure to unlock your LG V30 when you connect it to your computer.
Once connected, select a USB connection type like Media sync (MTP) or File Transfer, if you’re prompted on your device.
Then, open LG Bridge on your computer.
Select LG Backup to create a backup of your data stored on the phone.
If you wish to restore, follow the onscreen instructions on the LG Bridge menu to restore your device. Basically if your able to access your phone on the computer through LG Bridge software, it means that your phone is not dead. More likely, it’s just not charging so you’ll have to deal with charging problem instead.

Im having a similar issue. Except everything went fine for me. Successfully converted to US998, upgraded again to oreo, flashed TWRP, flashed the two LG specific files, installed Magisk. Everything went great. Unitl I tried to install Lineage OS 15. Then it went to the Lineage splash screen and stays there. Now I can no longer get into any recovery of any sort even when trying to do the master reset. Just continues to reboot and lands on the Lineage splash screen. I guess Im going to have to let the battery run all the way out and hope that I can get back into fastboot that way.

Yes. Sure have. I held the power button down for 5 minutes and nothing. It never powers off. The power button plus down works to reboot the device. And I can also get it to go to the factory reset screen, but when I do that it goes through the motions and then just tries to boot again. This is why Im assuming it has removed the recovery some how?

LG V30 vs996 doesn't stay in download mode or boot past Verzion screen

My friend was following the WTF V30/V30+/V30S Bootloader Unlock and Root and Frankenstein posts. He started using the Magstik to uninstall bloatware then tried applying a OTA update that showed up on the phone it restarted but never went past the Verizon load screen. The phone now no longer boots to where you can use the phone nor stays in download mode to use adb. On one computer sees the device as LGE Android MTP Device on another computer it shows it as that but the device needs troubleshooting. Anyone have any advice to get it back to where I might be able to get it functional again?
Thank you again in advance!

Why would he apply an OTA update when he no longer has full stock firmware? He had TWRP custom recovery!
Yeah, he messed up the phone.
Just to be clear WTF instructions -- that had nothing to do with his actions.
By this point he had successfully completed all those instructions and had flashed back to VS996 firmware.
The WTF Instructions tell you how to update your phone correctly once TWRP custom recovery is installed.
____
Try Master Reset from Frankenstein instructions.
Then if you can get back into Download mode, flash back to Nougat US998 via Partition DL, all partitions.
Master Reset again.
Then Refurbish to US998 Oreo 20h.
Your bootloader will still be unlocked.
Go through WTF INSTRUCTIONS SECTION 6 and re-install TWRP and the three root files again.

Thanks ChazzMatt, however I've tried the Master Reset and it doesn't seem to be doing anything to the phone. It presents the message about Delete all user data (including LG and carrier apps) and reset all settings. I select "Yes" screen goes black for about 2 to 3 seconds then I get the same message, Delete all user data (including LG and carrier apps) and reset all settings with Yes already selected. I've selected that or left it alone and the results are the same. Screen flashes LG V30 ThinQ up for a sec then the screen goes black for about 3 seconds then shows the LG V30 ThinQ again before going back to the Verizon logo screen.
Just to confirm: holding vol+ with USB plugged in during a reboot doesn't go to download mode for using LGUP. Also holding vol- with USB plugged in during a reboot doesn't go to fastboot mode for using ADB since you... Sorry, your friend, was running VS996 firmware, correct?
Correct, if I hold Vol+ and plug usb in I get download mode for maybe 2 secs but LGUP and computer doesn't recognize the phone then it begins to boot up the phone. I have the LG Mobile USB drivers installed as well. Vol- doesn't do anything. Yeah I don't know what my friend did but it doesn't seem to be good. I'm not even sure what ROM or version of ROM it has on it because he doesn't remember. All it does currently if I power it on is it sets at the Verizon traveling dots screen.

Find someone with an octoplus box and use 9008 mode to flash a kdz. I think thats your only option unless your friend can return it or warranty it through Verizon.
Then, dont ever ever take an OTA on a modded phone again.

LM-V600TM stuck in the boot loop

Hi everyone, I followed this guide here https://forum.xda-developers.com/t/v60-bootloader-unlock-and-magisk-root.4358785/ to root the phone with magisk. Everything went great up to the last point. I rebooted my device and I am currently stuck at fastboot mode as my device can't normally boot into stock rom I had before I tried to root it. Should I just flash stock rom on the device? How should I do that? I am still an amateur and can't figure it out by myself. My bootloader is unlocked. Any help would be much appreciated. Flashing backup boot images doesn't help.
Just put your device in the download mode. Here are the steps for you:
1. When you are in the fastboot mode, choose to turn off the device by scrolling though the options (via volume up/down key and then pressing the power button to select).
2. After the phone is off, keep the volume up key pressed and insert the USB cable into the device. Make sure the USB cable is attached to a computer before plugging it into the phone. This will put you in the download mode.
3. From there you flash the relevant firmware using LGUP.
The case is outdated, I managed to upload the firmware via LGUP
Hi everyone.
I have a similar problem. I wanted crossflash to EU.
When I was ripping and deleting the contents of the partition, the phone lost the usb connection and after reboot it fell into a loop. It does not report for usb and I can not turn it off. Is there anything else that can be done to save him? I erased the partitions FTM, Modem_A, Modem_B, SID_A, SID_B, OP_A - not OP_B.
I have a backup of them
I'm sorry, my english is bad.
You have two options depending on which one is available to you:
1. If you get into the QFIL then try to restore the deleted partitions. It is quite possible that other partitions have also got affected due to abrupt disconnection resulting from power failure.
2. Maybe you can get into the download mode. It will be tricky. Press and hold the volume down key and the power button till the phone restarts. Once it starts, press the volume up key and insert USB cable (that is already connected to a computer). Once there, re-flash the firmware.
Thank you for your help. I was able to start the phone in download mode and upload the firmware via LGUP.
Hello! I didn’t root anything, everything is stock. at some point phone just crashed and now it is stuck in boot loop. i was able to factory reset it, but nothing changed, it keeps rebooting. LV600AM
The problem, in your case, becomes complex because AT&T does not release firmware publicly (that you could just re-flash the phone with). How were you able to factory reset the V60 phone? Did you get into the settings menu and reset it from there?

I hope someone here could share with you a full AT&T V60 partition dump. Failing which your only option is to have AT&T restore it for you.
