First off, I appreciate any input on this very much.
The phone is an LG K8 2017, or model US215, and this is actually the second time this has happened on a second device. Both times this has occurred, it's been during charging.
The first time, on the first device, the device was off when I took it off the charger, and would not power on until I removed and replaced the battery. Later that day, the device seemed to be lagging, so I rebooted it, and was taken to the fastboot screen. I Googled and Googled, and corresponded with LG before taking the phone back to the retailer and exchanging for another, as I'd only had it a few days.
Now, with the second device, which I've been using for several weeks, there were a couple of times that the phone was off after charging, and the battery had to be removed/replaced to start it. This time, the phone was (maybe for the third time) off when I removed it from the charger. Fearing the same issue, I removed/replaced the battery, and unfortunately, was met with the fastboot screen. LG will repair it under warranty, but I don't have a backup, and can't go weeks without a phone. I've searched high and low, and cannot seem to come up with an answer, or find a situation identical to mine.
I've tried fastboot reboot with ADB, but it requires USB debugging to be enabled on the device, which mine was not, and I'm not able to access it now. The phone was completely stock. Hard-reset does not work, as it always boots back to the fastboot screen. I am, however, still able to access this screen, and download mode. I've tried to include as much info as possible, but am eagerly awaiting responses, so I can answer any questions. Again, thank you to anyone with input!

Thank you for the response! I see the link for the firmware, but I'm not sure what guide you're referring to?
[EDIT] I think I found it. Will update after I follow the guide.
Unfortunately, LG Mobile Support Tool just tells me, "The phone is disconnected from the PC." Even in download mode.
The only time the PC seems to recognize that the device is there is when it's on the fastboot screen, however, LG Mobile Support Tool still gives me the same error.

So I rooted my sister's optimus v about a month ago. Today she installed a battery mod app from applanet and as soon as she chose which battery mod she wanted she had to restart her phone for the changes to be applied, but when rebooting the phone it would only get stuck in reboot. So I tried to start it up in recovery and got the blue screen that says fastboot mode started. I looked that up online and found a fix to it but I need it to go into emergency mode to fix it that way and it will not go into emergency mode, any combination of keys only takes it to either the blue screen with the fastboot mode message or it just reboots and gets stuck. So now what do I do? I really need to find a way to fix her phone. Thanks in advance to anyone who tries to help.
try to turn on the phone & use LGMobile update tool. That should recognise the phone & install original lg fw

I managed to finally get the phone into emergency mode. I had installed the LG mobile support tool and installed all the drivers and tried to go that route but it kept telling me I only had one of four drivers installed, even though I have installed several drivers. After all of that I had finally got it into emergency mode so I went back to trying KDZ. I'm supposed to select the rom where it asks for the KDZ file right? But when I go to browse for the rom file it doesn't show up in the folder I put it in. I've rooted 4 phones and have done so many other things with them and never bricked one, was always able to figure out everything I did and never had to ask any questions but I can't figure this out to save my life and it is driving me crazy. I do really appreciate you guys for the suggestions and thanks to your suggestions I have gotten this far.
Hey, I have the same problem. I rooted my phone then I installed that battery mod app on applanet. I installed it then when I had to restart my phone for it to apply it just got stuck and kept looping the reboot screen where it says "ANDROID". Did you get ur fixed yet?

I'm having the same issue right now, although at least you have managed to get it into emergency mode. How did you do it?
The other issue I'm seeing is that there is no .kdz for the Optimus V LGVM670. I found a .cab file that is supposed to be the newest update, but not even sure that will work with the the kdz manager.
It was my sister's phone and I had the same problem with kdz. Had the cab file so couldn't use it with kdz. My sister left her phone with me for a few days to try to fix it and when I couldn't she took it home and managed to fully brick it to where it would do nothing at all so she had to get a new phone. I got it into emergency mode by holding down the volume and it was either the back button or the home button I pushed at the same time, can't remember which. As I held those down I plugged in the USB cord that was connected to my laptop and it went right into emergency mode. Just make sure you disable that LG modem in the device manager on the computer before doing anything because my sister forgot to do that and that is how she fully bricked her phone. Good luck to you guys and if anyone figures out how to fix it I would be interested in knowing how you did it.

hmmmmm, I don't remember completely how I did it, but there was a very helpful guide floating around XDA. I bricked my Mom's Optimus one as well . I actually had to go to the LG support site, type in my Phone serial number and find a list of all the firmware available. From there I right clicked the page and got the page source. From there I got my firmware and I entered it in the KAZ or LG B2I Agent ? - Dont quite remember. Anyways, it ended up working out for me, but I accidentally flashed the German firmware, but in the end, everything was all good LOOL.
I have the MetroPCS lgms769, I tried unlocking the bootloader but I guess I messed up some how. My screen had the touch screen problem, so I tried flashing again but now I'm stuck on security error. No matter what I do, I cannot get fastboot drivers to install for my phone. I've tried several times. It just sits there at waiting for omap44xx device. I've done the steps right to the T, My computer makes the sound as something connected then disconnected, then connected again and then once again disconnected. I've watched under device manager but I see nothing coming up, even when I do view all devices. I've booted into S/W upgrade mode but my phone is not detected. I can't boot to anything, it just goes to security error, shuts off, and boots showing my battery charging. I've installed all drivers through the LG website that goes with my phone. When my phone was working, I connected the usb and switched to every mode for it to install drivers. I'm on Windows 8 64 bit. Could someone please help me?

Funny you should mention this. I too have the same problem!! I spent all night to no avail! I managed to get clockwork to install, flash the backwards touch problem fix, but then when I attempted to install a Pacman 4.3 rom the phone rebooted to the Security Error Lg logo!! I can't flash any KDZ now because at 15% it loses a connection! I tried the Fastboot method and ADB just would not detect my phone! Pulling the battery out and having the phone connected to usb makes the device manager go nuts! Omap device pops in and out and wont stop! Thankfully I have the Tmobile premium handset protection package, so Ill get a replacement p769bk but OMG people don't try to unlock the boot loader on this device! Its not worth the risk and complexity/trouble!! Stick to root access and be happy! Wait and pray someone smart enough can figure out how to unlock the boot loader easily and with minimal risk! Before I messed with my phone I was on the OTA update v20F. I flashed to the V20B 760 KDZ and used the hex edited bin file that goes with it. Just don't do it! Its not worth the backwards menu/logo/touch headaches! Be warned!
I wound up taking it back to metropcs and I'm getting a new one in 3-5 days, they didn't charge me since the guy said it was a software problem and I was still within the 30 days

Good deal. Like I said before to anyone who reads this post:
Head my warning or you'll probably end up like the both of us!.
I really like this phone but damn! Why does LG have to lock the boot loader..? I miss having Cyanogen Mod. I mean my old P999 G2x wasn't this hard to get CWM/Root on it!
Somebody save the day! Find the key to a simple boot loader unlock! (V20F) This phone deserves it!
Hey you posted in the wrong place, anyways fastboot probably didn't work because you are on Windows 8.
If you try again, use this http://forum.xda-developers.com/showpost.php?p=45102887&postcount=1
This is the official program to restore from security error & other problems.

Thanks for trying to help but I tried to use that app and it still failed to detect my phone. I don't think I'll try it again. We need a new one click wonder app before I'll attempt this again. Also I don't think I like having a backwards LG logo stuck on my phone, ( I did not know that was going to stay there) yet alone some strange image mirror bug with the lock screen. It corrected itself if you hit the power button and wake it but if you reboot the phone it comes back.

Hello
I need some advice and help if someone can.
My LG V10 was rooted and on latest Eliminators room. It was working perfectly and few days ago while ending the phone call it just switched off.
Since then i have been trying to bring it back to life but without any success .
I can boot it to fastboot but no commands are accepted in fastboot mode, no download mode . It only goes to logo and the information that software can not be checked , further from there it goes nowhere . Since i am mac user , i installed VM of Win 7 and only thing it detects is Qualcom 9008......
Please some advice and help what is possible to do.
In fastboot mode i can not do anything.......

This is the exact thing that happened to me last night too. I was wondering if my phone pushed the latest update on accident or something to cause it.
Another thread in the Q & A Section has reports of this happening and maybe being a hardware issue.
I plan on trying to do a full restore back to stock tonight when I get home from work to see if I can bring it back to life. I also read somewhere that you need to have the latest binary for fastboot to work.
The few minutes I messed around with it last night, my fastboot was sending but not writing. I'll keep you posted it I have any success tonight after work.
Side note the thread I mentioned above the S/N for the phones having issues started with 510...
Also, I can get mine to boot into recovery but once I try to erase or install it freezes and boot loops again.
I will play with it from tomorrow again. From yesterday i have gave it to one service center but they have not succeeded to do anything. I have succeeded in one moment to get to download mode which laster only about 2 seconds, not enough even to connect it to lg up, suspecting tht it is maybe something because of VM that doesn't' discover phone complerely. Tomorrow morning i shall pick it up and during next few days i shall try again, if i succeed to find a solution it would be good. I was also planing to do complete factory back up to stock last version. But...

I have the same problem with my v10 do you found a solution ?
No. I bought a new phone and my v10 is now a paperweight. I have not really tried too fix either. Jumped on project fi and got a got a 5x on the cheap. Couldn't be happier.
I've had luck flashing my LG from within a virtual machine, running on top of Linux Mint. I tried both VMware Workstation and VirtualBox. Just make sure to install the guest additions within VMware, or the extension pack within VirtualBox. Also download the LG driver and install that inside the VM too. Each VM software may have settings relating to sharing a real USB port with the VM, make sure you look into that and enable the relevant options. Otherwise the VM may not detect the device.
On the other hand, my v10 isn't hardbricked, I'm just going to hold onto it as long as possible until it goes belly-up. Which it will probably do sooner rather than later, if the issues I've had are any indication. If you're only seeing Qualcomm 9008, fastboot not responding to any commands, and no download mode, this def sounds like a hardbrick. If you're still under warranty I would recommend getting it replaced by LG. If you have insurance then cash it in.
This is the 3rd v10 I've had, so far I've done 2 exchanges if I remember correctly. These phones are definitely susceptible to big issues. Like the now famous LG bootloop scenario.
Hope you get this figured out!
Hi hello
So here’s a head scratcher I hope someone can help me with that won’t involve replacing my main board.
Got myself the p20 lite (ANE-LX1 C432) - Single Sim.
I unlocked the bootloader with Huawei just before they stopped handing out the codes. All was good and happy with the world.
Rooted with Magisk and Was busy messing around With Termux, Linux deploy, Mobile Terminal and some pretty basic stuff. I’ve been out of the android scene for a while so was getting reacquainted with the scene.
Anyway. I was messing around in the terminal in a root shell just fixing basic permissions after messing up my termux environment as root. Phone randomly rebooted (I must’ve messed with the wrong folder -no idea which) came back on and my IMEI and baseband were gone.
No worries, I thought. Happened tonnes of times with my previous Devices (looking at you Samsung) just a quick restore or flash and all will be happy again.
Yeah, not quite.
Note that up until this point I hadn’t touched the system partition (probably besides the mobile terminal mishap -no idea)
So over the last week or so I have tried everything. Restore from Twrp backup. Flashed stock through fastboot, through erecovery. Those flashed ok but didn’t fix it.
Putting numerous different update.app FULL & OTA updates in dload folder on SD and internal all failed. Only used my builds version of course and only ones firmware finder deemed compatible/available
Then I got desperate (read: stupid) Decided to take the unpacked firmware files and flash whichever ones twrp would let me. First tried just the modem files. Didn’t help. Then just went through the list and flashed all I could.
I think the kicker came in when I installed the Trustfirmware.img because once I did that I rebooted and now I was stuck in an endless boot loop. No way to get into recovery. Not with their ton combo nor adb/fastboot.
I still had access to fastboot at this point at least and started doing every single thing suggested all over the net just trying to get back to stock.
Tried the unbrick option on The Huawei Multi-Tool. Flashed ok. Phone still wouldn’t boot. Did it a few times with 3 approved versions. Nothing. Only access to fastboot otherwise I was in a boot loop with error mode error no 15 and the verification failure (Attached below)
Last thing I tried after reading online was to relock my boot loader and flash stock. So I locked it with Huawei Multi-Tool. Reboot......
Now I don’t even have access to fastboot. My PC’s (windows and Linux) don’t even acknowledge it and holding volume down in all the weird and wonderful ways and times does nothing. All I get is startup Huawei Logo, Error Mode as per pic Below and then reboot. That’s it.
I’m assuming it’s trying to do a factory reset after relocking the bootloader (if it even locked properly, can’t check) but it can’t get into recovery/erecovery. I dunno ?
That’s my essay of where I’m at. Warranty is already void so not an option and I don’t want to buy a new mainboard (may as well buy a new phone).
So here I am. Is this my life now or does anyone have any magic tricks to possibly suggest?

Thanks for this.
The battery discharged fully about two days ago.
I haven’t tried plugging it in and out as/if it turns on immediately (though even though it shows dead without charger it still comes on immediately).
I’m gonna get a weaker lower amp charger and see if that maybe helps. Fml ?
***UPDATE***
Been at it for hours. Battery is completely flat. But h second I plug it in the the Black Huawei logo comes up ten a few seconds later it’s on the same error screen for a little longer then boot loops like that constantly.
The error isn’t the same as the post in that link though. And I am FRP unlocked.
Eh.

I guess your previous error was related to ramdisk...
Now what is your current situation?
-What error is showed in the Error mode?
-Can you reach FASTBOOT&RESCUE MODE menu?
-What is your current recovery?

As it stands I cannot enter fastboot or recovery mode. Update from SD also doesn’t do anything. Battery is completely discharged. And if I leave it on the charger it doesn’t charge, only boot loops.
So with all that the ONLY thing this phone does now is:
- Starts up Showing Huawei logo
- Error Mode Screen with Func No: 15 (bl31 image) & Error No: 1 (security verify failed)
- Reboots
Ths happens whether it’s plugged into the pc’s usb or the charger. Tried all combinations of buttons too.
It has stock recovery as I flashed that back when trying to revert back to stock.
I lost access to fastboot after I locked the bootlaoder again using the Huawei Multi Tool. It’s like it trying to do the factory wipe that it usually would after locking/unlocking the bootloader but is unable to due to the error mode screen.

I see, it is really bad
My last hope is to be able to do a forced Firmware upgrade. Press power button and VOL + and VOL- simultaneously. Do you see the same as the attached image?

Ah man, I wish it would even do that. It makes no attempt to even pretend to see the sd card update. If I hold all the buttons in it still only comes up with the error mode and reboots.
I popped it open and connected a charger up battery to see if that would help but it doesn’t.
Do you maybe know the pin layout on the inside or know where I could get schematics? Been looking everywhere.
I’m almost done building my own Jtag box and am hoping to bring it back to life by writing straight to the damn thing.

That is sad!!!
With JTAG and schematics stuff I cannot help you.
What I found recently and it was new for me (I didn't tested yet) is a possibility to install firmware via "dload" folder, but to start installation the stock recovery have to be full functional.
If I found something interesting for you I'll post here.

To my knowledge the recovery is installed. Well erecovery. It was working up until I locked the bootloader again and it went into a boot loop instead of doing the factory reset.
Is there any other way to force sd update other than with the dload folder?
Thanks for tying to help, I appreciate it.

Still unsolved as of yet.
I’ve finished building my own version of the Riff/Octoplus box as well as a makeshift Jtag. I’m still trying to find and piece together some firmware files and other board software I think I need.
Also, if anyone has any idea where the test point is on this board I’d really appreciate you pointing it out. I cannot find the schematics or any solid documentation anywhere.
I will attach the pics I have of both sides of the board as soon as I get home.

well, try to restore your device using dload method. It needs you to copy the UPDATE.APP in dload folder of an external sd card(formated in NTFS format) and then just press both vol up+down along with power button for a few seconds. It will auto launch huawei e-recovery and will try to flash the UPDATE.APP you stored in ext sd card. This should definitely work.
Dload method doesn't need you to unlock your device or bootloader.
Maybe?
I know it’s a long shot but I still have this phone. If anyone maybe knows if there’s been a way to fix this as of yet please let me know. ?
Lol. Still got this damn thing. Been searching around and seen a few people reporting similar errors. Never find out if they ever solve it though.
So. Anyone maybe have any knowledge to share? Anything at all.
I don't know if you still have your device, but I had the exact same issue with a P10 (VTR-L09)
I was able to fix fastboot using https://github.com/mashed-potatoes/PotatoNV
That tool was designed to unlock the bootloader, but I noticed that It actually flashes a slightly modified version of fastboot.
PotatoNV can also unlock P20 lite bootloader, so you should give it a shot.
Good luck!
If it works, you should be able to flash stock recovery image and then restore the system using the dload folder.
you can Repair it with Software Testpoint and Full Bootloader Unlock ,and then flash a Board Software via Software Testpoint, that helps 100%!!!
use this Firmware Download ANE-LX1
use the Software with logins and you have all what you need.
you must start the Software Testpoint so!!
VIDEO : how to start Software Testpoint P20 Lite
than in Software Testpoint you flash the included Board Software with DC-Phoenix and after that use the included dload update via sdcard and eRecovery mode and your Phone is running!!!
I would unlock the bootloader via Software Testpoint with DC-Phoenix, then the FBLock is unlocked and you can flash as you wish!!!! And the great thing about it is that you don't need an UnlockKey either, you can then read this with HCU client software, the only thing that's stupid is that you need a time-based license for the two programs, which you have to buy.

DC Phoenix download

Since I accidentally bought a 3-day license twice and my P20 Lite is now completely rooted on Lineage 19.1, I can give away 2 access data, which are still valid for 2 days.
you can edit your smartphone with it.

Then I wish you a lot of fun with it, hope it helps you if someone else is active in this thread.
So as the title says, my phone is stuck with a no command screen and i think it is going through a boot loop along with it. so hears the backstory. Its a used phone, bought through Facebook [not such a great idea, but i bought a note 10 last year for half the price brand new, cant win every time though]. the seller failed to mention that it was rooted. and in a haste one day i deleted my conversation with him (not archived) when i was cleaning out my messages.
When the battery died i saw the first warning, stating "Your Device software cannot be checked for corruption. Lock Bootloader. Visit this link on another device: g.co/abh" that's when it got stuck in a boot loop. It may have received a update, im not sure. I visited the link which is for google pixel or nexus phones. so i brought it to a repair shop and local businesses will not work on it, because its been rooted. well i managed to get it working again, only by doing a factory reset. Ive had to do that twice. then one day i magisk had a update. i did it. and YAY its fixed. me being me wanted to unroot and lock the bootloader so it would be back to default. Nope. I uninstalled magisk. and boom i have the no command boot loop. i have tried using the LGUP program, but with it being att that got shut down real fast. I have looked all over for information. but i need it dumbed down. I catch on quick but a lot of the terminology is lost on me. I may have forget to mention some things. so please anyone who can help. any info would be appreciated.
So after much button combos and almost just chunking the phone. I managed to get it into download mode. by pressing and holding Vol- and Power button to get it to restart. (phone is unable to power off. unless the battery is 0%) While screen is blank, press and hold Vol+ while plugging usb into the phone. I had the cord in the computer first. it may work vice versa. Looking for AT&T official Firmware now. I think.
Brother, I request you. Please tell me how you did that.
i cant do anything. i have the exact same problem
Please guide me step by step.
