[Q] Help with seemingly perma-bricked LG G2 (VS980)

Hi all -
Thanks for checking in on my tale of woe. The summary is that I have seemingly nuked my partitions on my LG G2 (Verizon Edition VS980) so that nothing happens when I try to power the device on (literally nothing, no logo, no screen backlight turning on, etc.). In Windows, with some coaxing, the device will appear as a QHSUSB_BULK device (with a yellow exclamation point in Device Manager, and even when I boot into Linux to look at the partitions, they aren't visible.
How I got here:
I was happily running XDABBEB VS980 2.3.0 from http://forum.xda-developers.com/showthread.php?t=2715408 with a few Xposed framework tweaks. Great ROM.
I dirty-flashed XDABBEB's VS982.5 v1.0.0 from http://forum.xda-developers.com/verizon-g2/development/xdabbeb-s-vs982-5-v1-0-0-t2975551 to have a look at the G3 interface. I did a Nandroid backup first, like any good crack flasher
I neglected to read the 2nd step of the VS982.5 thread carefully enough - about the fact that this ROM was bumped. I still am not sure what that means.
I played with VS982.5 for a bit, and it didn't really seem like I'd want to use it long term. Also, some of the LG apps didn't seem to work on first try, not sure if that was an additional flash required. (QRemote was what I ran into). Anyway, I thought I'd go back to VS980 2.3.0 for then by just restoring my Nandroid.
Booted into TWRP to restore the Nandroid. It did it's thing.
Upon reboot, the device showed the LG Logo and showed a Security Error in the upper left-hand corner, and sat there briefly, then shut off the screen. (Sorry, I don't remember the precise text, it was in small white letters, several lines' worth of text).
I tried rebooting a couple of different ways, and eventually gave up and followed this guide: http://forum.xda-developers.com/showthread.php?t=2582142
From a Linux Live CD (Specifically an old Hiren's 15.2), I thought I'd followed the instructions correctly. The partitions did show up correctly under /dev/sdk1.../dev/sdk36 or whatever. I did the dd as prescribed with the files.
Then I tried to reboot, and here we are. Apparent hard-brick.
What I've tried since the Linux fiasco.
Rebooting many different ways. (Recovery mode, etc.)
Going back to stock with kdz and tot methods, following this: http://forum.xda-developers.com/showthread.php?t=2432476 . The device is not recognized, probably because the normal USB driver won't load.
Checking to see if it'd show up in adb and fastboot commandline interfaces. No, of course.
Booting back into Linux to try the dd again. No luck. The 30+ partitions don't show up under /dev
Letting it charge, thinking the battery may have died. It has been plugged in long enough that it should be 100%. (I can't tell when the device is on or off any more, because there are literally no indications.). This doesn't seem to have made any difference
Holding the Down button and plugging in the USB port gives the QHSUSB_BULK (Code 28) error in Windows, so at least it's doing something... but not much.
Ideally, of course, I'd like to restore the partitions, get my nandroid written back to the device, and carry on with life. Failing that, I'd like to get the nandroid off so I don't have to spend hours setting up another G2. My mistake for keeping the nandroid on the device - I've never bricked a device this badly, and it's always been recoverable with some googling!
Help!
P.S. Sorry about the cross-post from the General LG G2 Troubleshooting forum - I hadn't realized there was a VS980-specific one.

I had this happen "going back" to a nandroid after testing the new G3 ROM myself...only I was able to boot recovery after the security error...you can't I'm presuming?

I couldn't boot into recovery. But yeah, my device is far past that point now - it seems to be pretty busted.

I'm a newbie that also screwed up his phone after trying xdabbeb's new G3 ROM. Seems like a lot of people doing this. Took a long time, but I was able to get back to stock with the LG Flash tool method. I was able to get into recovery and flash xdabbebs 'restore download mode' file though.
If you don't have recovery or download mode or fastboot screen, I think you are permanently bricked. But I'm a newb, so hopefully some experts will chime in here.

Yeah, my main issue is that I can no longer get my drives to mount in ANY fashion, I just keep getting the QHSUSB_BULK busted driver. in Device manager. I don't know if there is a driver that I can install that'll enable the partitions back in Windows, and I don't know how to install additional USB drivers in Linux.

Thanks - I tried that in my step 7 already, in both Ubuntu and Slax. The dev/sdk1-36 partitions no longer show up.

I thought I'd update this story to let people know how it ended.
I ended up ordering another LG G2, but saw this thread late one night:
http://forum.xda-developers.com/lg-g2/general/fix-unbrick-lg-g2-stuck-qualcomm-hs-usb-t2933830
I had to make a Windows XP VM to get it running with the HS-USB 9008 mode, but after I did that, I kept getting the "device was not found in dload trying flash programmer" error.
I ended up contacting one of the guys in that thread who did a teamviewer session with some custom build of the b2b support tool, and he was able to unbrick it. He does charge for the service though.
It wiped the phone, but it is back in service now under XDABBEB's 2.3.0.
So now I have a spare LG G2 on its way.

Help with Nexus 6 possible Brick

Alright I am looking for some help here. I was attempting to unroot to update my Nexus 6 to Android M. Not sure how this happened but here it goes. I can boot the phone into recovery TWRP and into boot loader but the OEM is locked....In recovery I have no backups or ROMs o flash and my mac is not connecting with the Nexus 6. It seems like there is no ROM on the phone at all and I cant use Terminal commands I keep getting Failures. I have run the 1 click root and unroots for mac and still nothing. I also have no access to Developer options since I cant load into a ROM...So I cant select allow OEM unlock... Please let me know if there is anything I can do to fix this. Thanks for your help everyone!

Try to uninstall all drivers then re install to see if mac recognizes your phone then sideload a rom to recovery or adb

Had this before. I believe when connecting to your computer, you have to delete every nexus 6 previous connections so it would be as if your phone never connected to your computer before. Then after you do that, it should install drivers and recognize your phone. I'm not sure if I remember correctly but I believe its from your toolbar on your computer where it normally pops up "eject USB " warnings. Sorry if I couldn't help

Delete all drivers relating to Android. Download and install the Android SDK Tools from Google. Update the SDK and install the Google USB driver. Boot into TWRP, connect the N6, then use adb push rom.zip /sdcard.
I think that should work.

or fastboot wipe user data and cache.

I have been working on this since last night 7pm... I tried adb push and it just sits there and says starting adb sideload for about 10 min then vibrates with a cancellation. I tried removing Android File Transfer and reinstalling it and I still get the can not find device error. Im thinking this might be a loosing battle.

I did both of these to get past the TWRP boot loop. I can get into TWRP but its empty like everything has been wiped I have no backups or ROMs to flash to. Since the OEM is locked and I cant launch into a ROM to select allow OEM unlock it seems like im going to inevitably lose this battle. Last resort I have a friend coming over with Windows (hoping) WUGfresh can solve the issues....

did you have any roms on your phone before all this? if you did, did you try to search if they are in a different location in your storage now?

Do you have access a a Windows machine? NRT has an option to reflash a bricked phone. Never bricked mine but that tool has been awesome otherwise.

All due respect to the developer, but all WUg's NRT does is automate the downloading and the commands you use to flash manually. It doesn't do anything "special"

True, but have a Mac, and it is rare that being in recovery and connected to the Mac, do not recognize ....
then wait a Windows computer then ....

FIX! we got it!
Thanks for all the responses guys! We spend another 4 hours on this Sunday and finally got it! We ended up using this forum step by step. http://forum.xda-developers.com/nexus-6/help/info-nexus-6-nexus-9-enable-oem-unlock-t3113539
While my friend was installing all of the ADB drivers on his PC I attempted the steps on my mac. It made it through the first to lines of code but when rebooting into Boot loader it came back with a fail notice to unlock the OEM.
When he got all drivers installed we used the same lines of code (modifying C: for the location he had the ADB drivers) and it accepted all codes. Seeing that screen change into the OEM unlock select yes screen was a GREAT moment lol. After that we used NRT to flash Marshmallow...
All in all it was fun trying to figure this out! Not so much fun thinking I had to drop another $300 to get a new phone! Again thanks everyone for the help!

Stuck in Fastboot Flash mode, Developer options turned off

I've followed all of the steps from this guide: http://forum.xda-developers.com/showpost.php?p=56938530&postcount=1
I've got to the end where I am running the code snippets to flash everything, but everything fails. The error stated is FAILED: remote failure. I am not sure if this is related to my developer options being turned off, but I think it might be.
Is there a way to turn developer options on while in fastboot mode or perhaps a way around this error? The reason I am stuck in the fastboot is because the boot image can't be validated, I am not at the fastboot by choice, haha.

No. If your recovery is still stock, flash the Android N Preview 1 OTA or an Android 6.0.1 OTA image from Google. One of those will restore your Nexus to operating condition, and from there you can try again. If your recovery is TWRP, flash a custom ROM.

I apologize for my ignorance since this is all new to me, but could you explain a few things to me.
Is this what you're referring to when you say Android N Preview 1 OTA: 'https://developer.android.com/preview/download.html'
Secondly, in order to flash these, am I still following the steps I was before, or should I be following a new set of steps?

You don't need the N Preview anymore. Download your Android 6.0.1 image from the Google page and flash using the instructions given on that page.

I went to the page and followed the directions. Still doesn't work. The flash-all script reboots after the first two commands, which lock the phone. But even then, it is still giving the error FAILED:remote failure.

me too!
I seem to be having the exact same issue! i just bought a Nexus 6 online that wasn't booting, it would only show a green led when plugged in. so here I am doing everything I can think of to fix the issue but then I get hit with the "remote failure" when i try to oem unlock the bootloader! (and since the phone wont't boot i can't check the "unlock bootloader" box in the developer options) so yeah I am going to keep researching this but if anyone has any good ideas about to get around the bootloader being locked please jump right in.
anyways I may have deeper issues, the battery will not charge. i know this because when i load up the fastboot menu, which i have to do by holding the buttons while plugging it in, it should say battery charging but all it says is battery ok
I also can't load recovery because when im in the fastboot menu and i choose recovery the phone freezes and the green led comes back on... *sigh*

They have the full ota packages posted on Google site now you can and push through the stock recovery
Here just make sure you get the shame version

I have the OTA. I also installed Wugs toolkit.
My phone is in fastboot mode due to the boot image not being able to be validated. I didn't voluntarily open up fastboot using the shortcut.
The phone is UNLOCKED until bootloader is rebooted, then it is LOCKED. If I click start, it becomes UNLOCKED again. Wug's toolkit tries to UNLOCK the phone even while the phone says it is UNLOCKED. I don't think the phone is actually UNLOCKED, however whenever it tells me it is UNLOCKED, I try to proceed with flashing and it gives me a remote failure message on each command.
The next thing I am going try is the drivers and Wug's toolkit has a driver option, so I will try that. Besides the drivers, any other ideas?

You seem to be inexperienced in rooting Android devices. If you aren't, I apologize for the assumption. However, you should learn how to use adb and fastboot without relying on the toolkit. Toolkits tend to hide diagnostic messages that adb and fastboot generate while running. This missing information makes solving problems much more difficult.

I am inexperienced, I stated that earlier. I have check a bunch of different forum posts and a bunch of different guides. Nothing seems to be helping and it seems like such a simple problem, a boot image that can't be validated. I am not trying to do anything special with my phone, I am just trying to get it to work. I woke up and it was stuck in this 'AP Fastboot Flash Mode (Secure)' mode. It is very bare bones, not even similar to the screens within videos I have seen. One moment the phone says it's UNLOCKED, the next it's LOCKED.
You are the expert, I am not. I am merely following your directions and they don't seem to be working. I did some outside research, came to a toolkit. Toolkits are great for beginners, especially since they are UI built, are built by someone who knows the area of interest, which makes researching easier and more efficient, but on top of that, it seems to be getting me much farther than your advice, although nothing is successful at this moment.
Here is a little more context into my situation. My phone seems to be recognized by Fastboot, but not ADB (From what I found, fastboot will find devices in fastboot, and adb will find devices functioning normally, don't know how true that is.). In addition, my phone seems to switch from UNLOCKED TO LOCKED after reboots, but can become UNLOCKED again if I push ANY button. Every command I issue (i.e flash bootloader, flash radio, flash system, flash userdata) result in the message, FAILED:remote failure, which I am not sure how to avoid (I have googled, checked these forums, checked other forums and there doesn't seem to be much, if any documentation on the error), but I think it is related to the fact my developer options are turned OFF. My next course of action is to install new drivers (I checked my drivers which are said to be up to date, I also installed google USB driver through the sdk, but now I am going to look into an adb or universal driver?) and attempt to rerun everything successfully.
If you have any other ideas, or don't think its the drivers, feel free to bring it up.

As a couple of fellows said before, try this:
https://developers.google.com/android/nexus/ota
Flash a FULL OTA from the link above, not a factory image. To flash any OTA you don't need to be unlocked. I think you might be confusing the terms (with the OTA you don't have to flash anything using fastboot)
In the link there are the instructions, it's pretty straight forward and easy if you have the correct drivers installed.

OTA requires that u can startup into recovery, I cannot I can startup fastboot through key combo but when I go to select recovery the green led comes back on and the screen displaying the fastboot options remains static
I think the phone freezes because it does not appear to be able to use the battery. though there is a firm battery connection it will not charge or power on without being plugged in. maybe when I select recovery I can quickly unplug and replug the USB and maybe hold the power button to try to simulate a successful reboot.. idk just thinking aloud and working with what I got..

I also can not start in recovery mode and the OTA requires ADB, which isn't recognizing my device. I have also stated that I have followed those instructions, and nothing resulted from them, except the same messages I have been stating these last few posts.

I will try this first chance I get later tonight..

Listen the ota doesn't get installed through fast boot, you have to select recovery through the fast boot then install the update by pushing it as bootloader does not need to be unlocked!

Ok, well it seems we are at an impasse. You seem to think I can do something, so I am going to show some pictures of my screen. Its going to be blurry because I had to take it with my computer, so I apologize, but I will elaborate on each picture.

The first two pictures are when the phone is 'UNLOCKED'. The second two pictures are when the phone is 'LOCKED'. The moment I press anything in 'LOCKED' mode, the little android man goes away, and it becomes the first two pictures. WHENEVER I push a button in 'UNLOCKED' mode, nothing happens, except in the bootloader logs screen says, 'FAILED TO VALIDATE BOOT IMAGE RET -1'. I have done everything on that OTA page in every way possible. It has done me no good.

Ok, I made a little progress I think. Wugs toolkit allowed me to use TWRP on my phone and ADB is recognizing my phone now. There are a lot of options within TWRP though, so I am going to look through them all for anything relevant. Anything I should keep an extra eye out for?

If you can use twrp just download a custom ROM to your phone and move it over to SD card and flash it, then you will be able to boot and unlock the bootloader in developer ootions, that is your best bet, if you keep getting force closes after flashing a custom ROM your going to have to do a factory reset from within twrp

I don't have an SD card, can I move it to the internal storage? And how exactly do I do this? I can't copy/paste anything into the phone (it says the phone doesn't actually exist, even though adb is recognizing it as in recovery) or do I sideload it? When I try to sideload it though, the device disappears (and device manager sees nexus 6 under other devices, but the driver isn't up to date and no drivers seem to work. I've tried the google usb driver with no luck.) and it won't allow me to sideload it.

ADB Works, Fastboot still "waiting for any device"

I have been blundering my way though the internet to get my ROG Phone 2 rooted. I have unlocked the bootloader, I have a modified boot image from magisk, I have the ADB connection set up through USB and it works fantastically. I honestly don't know how I got it work, it involved many different driver update attempts and then figuring out I hadn't put the phone into USB debugging, but now fastboot doesn't work.
ADB will list the device, but fastboot cannot see it. I have tried rebooting the phone into the bootloader, but there is no connection on either. Not sure why I thought that would work, but I tried. I really don't understand enough about fastboot to get any farther on my own.
I have the tencent version and I was pretty certain I have the CN android 9.0 on it, but I am no longer certain of that. I am running windows 10.
This is my build number: PKQ1.190414.001.WW_Phone-16.0622.1906.19-0
I honestly don't know, but does that WW mean my tencent phone is running the WW firmware?

Fun fact, I just got Fastboot access from my computer by using the side USB port and rebooting into the bootloader from ADB. Still not to sure about the version bit. I think I'm just going to give it whirl and brick my device, maybe.

1. You are running a WW rom, but that doesn't necessarily mean your fingerprint is matched. To update you need to have both WW rom and WW fingerprint. You can check if your fingerprint is CN or WW using device info hw from playstore under 'system'
2. In order to root you need to have a matching root boot img for your current rom ie root img for 1906.19, just checking that your know this?
3. Have you managed to get the phone recognised using the cmd 'fastboot devices'? Also are you using the side port?
4.when you say bootloader, have you definitely got the phone in fastboot mode - hold vol up and power button until you see the screen with some options. That screen is fastboot mode, you don't need to select any further options. Once in that mode, connect to pc, open adb and run the fastboot devices cmd. Once your device is recognised, report back here for further steps

Thanks for the reply! I did indeed get fastboot to work over USB. Fastboot devices reported back the serial number and everything. I did not know that the build need to match on both the boot and the rom, but that does make sense and I probably should have realized that before I went ahead and copied the rooted boot.img I had over. Then my phone couldn't boot up proper, and got stuck in fastboot. Then I went ahead and copied all of the contents of the same rom over and now it is literally just a black screen. Won't turn on any more. I think I super bricked it.
Sorry I didn't see your post earlier and I know I am not father into the deep end, but is there a way out from where I am.

Nope. The only response I can get out of it now is when I plug it into the fastboot port, the computer recognizes that something was plugged in. I don't even get a device on a device manager.

Try holding the power button for around 20 secs until it shuts down. Then try vol up and power together and see if you get back to fastboot. If that doesn't work try vol up vol down and power buttons all together. Then try again to put it in fastboot mode using vol up and power. Let us know what happens /if you can reach fastboot mode

Unfortunately, nothing. Holding power for 20 seconds showed nothing, and like wise for volume up and power. Battery was fully charged too. Had it plugged in for most of today while I was trying to get fastboot to work.

Is there any sort of illumination to the black screen ie do you think the phone is on but the screen is black or do think the phone is completely off?
Holding power button for a while should switch it off after a while. Try holding for longer than 20 secs, then try booting into fastboot mode

Try a USB 2.0 port? Surprisingly this works for some phones even though it's compatible with 3.0.

Well, It's been untouched for a day now, and it still will not react to input. No response from long hold on the power button. I will try again in the morning. Is it possible that I somehow wrote into the BIOS of the phone? Android does use a BIOS, right?

Android itself does not have a BIOS, since Android is an OS and BIOS is more similar to firmware. But yes, the phone does have firmware, and it could be that the mismatch in firmware versions (from which you tried to flash), has caused the bootloader to "not know what to do now" when trying to start the phone up.
One thing which comes with all phones with a Qualcomm chipset is something called Qualcomm Crashdump Mode. You can try to see if you can get your phone in EDL (emergency download) mode and restore the correct firmware in that way:
https://www.the***********.com/rog-phone-2-unbrick-guide (URL gets censored for some reason; it should be "the custom droid" with no spaces)
Also, if you continue to have driver issues with connecting the phone to your PC, are you able to test another PC or even a Mac if you have access to one? I find Windows can be a giant pain for getting ADB and fastboot to work properly at times.
Good luck and let us know how it goes.

Ok, so here's where I am: I have left the phone unplugged for a long time now. Really had no effect. I just downloaded QPST and I can actually get my computer to see the phone. However, I am still not quite sure how to USE QPST and not make things worse. So this is my plan: I am going to look through the forums here for info on how to use QPST to get my phone working again. Not really sure what that will look like, but fastboot would be a good start. From there, it sounds like I have to get the original firmware back on it, and then go about the process of rooting once again.
Still leaves me with the issue that started me down the path of rooting this phone, but at least it will not longer be bricked.

You may not HAVE to flash complete firmware, it is quite likely that the boot.img is causing the problem as you flashed an incompatible version. Below you'll flash the correct version which HOPEFULLY will fix your phone, provided you can get into fastboot mode now.
Haven't read back through all the thread so i can't recall all the details of where you're at. As far as i can tell you're still running WW 16.0622.1906.19-0, correct? Can you get the device to now boot into fastboot mode? (from a powered off state, press and hold vol up and power at the same time. You should then be presented with some options, DON'T select any option. With that menu screen open is fastboot mode.
1. Download and install ADB Fastboot from here to C: drive of your pc/laptop.
2. With your phone in fastboot mode (as detailed above) connect it to pc/laptop using the side port of the phone.
3. Navigate to C:\Program Files (x86)\Minimal ADB and Fastboot folder and double click the cmd-here.exe, this will open a cmd window.
4. Type 'fastboot devices' to check that it's recognised, there should be a serial/key shown after entering that cmd.
5. Provided the serial/key is shown in fastboot mode, download the following boot.img (which is for WW 1906.19) from here.
6. Copy that boot img to the same folder you have open for ADB (C:\Program Files (x86)\Minimal ADB and Fastboot)
7. In the cmd window type 'fastboot flash boot boot.img'.
Now, that boot img is the STOCK boot img for your rom version. Don't worry about rooting for now (if i recall correctly, your phone won't boot to system), let's just try to get the phone booting first. Providing there are no errors when flashing the boot img, on the phone fastboot menu, scroll through and choose 'restart'.
Let me know if the device boots to system now... Good luck
I'll pm you my email address so you'll be able to get hold of me if you get stuck at any stage...
EDIT: was forgetting you tried so many times to get into fastboot mode, without success.

Dude, is your phone screen still black but switched on? When you tap the screen does it vibrate. I'm thinking you might already be in edl mode (which could be a good thing). Let us know
Check your pm's dude for further info. I can't post links to the site required so have sent via pm

Just dropping you a quick note to say thanks for thanks! LOL. Yeah, your post earlier seems like the best place to go. Have used Miflash Tool a few times on Xiaomi devices, it's pretty good and straight forward. Should be a LOT easier than using QPST and having to change EMMC to UFS.
Can't remember where i saw it now, but i'm sure i read that if the phone screen is black (but switched on) and vibrates, then it's likely to be in EDL mode already. Which will hopefully be good news for @RichDoe252. Before that (having never been in that situation), i wasn't aware that an all black screen could mean EDL mode is active. Fingers crossed for Rich it'll all work out just fine.
@RichDoe252 If all goes successfully using the QPST file download (and using the Miflash Tool the guide mentions in the pm i sent you) and flashing, DON'T ROOT JUST YET!!!! LOL. Let us know how it goes and then we can look into, and point you in the right direction, for getting you rooted and up to date on latest A9 or A10 whichever you'd prefer

Well I must say Rich, I'm surprised you haven't been back here yet to give any updates on progress!! Sent you a couple of emails through pm... Man, if it was my fairly expensive phone that was in the poo pan, I'd be all over trying to fix it lol

First off, you are a freaking saint. I really do appreciate all the help you have been offering up, and I am sorry I have not been very quick with a response. As my phone currently stands, I get 0% response from anything I do to it. No vibrate, nothing. No indication it even is plugged in. I had it connected to my PC with QPST installed, and it was able to pick up that the phone was there, and then immediately tried to download something to it. Not sure what, not sure why, but that kinda typifiies my interaction with this whole process so far. If you haven't guessed, I'm kinda in over my head.
Back to the problem: QPST started some opperation to download something to it. Wouldn't let me do anything else, said the phone was in "download mode". Either way it stopped at 30% and didn't progress for 30 minutes, so I tried to unplug it and plug it back in. Same interaction. Unable to do anything to the phone, no reaction from the phone what so ever. This was, by the way, plugged into the fastboot side port.
I saw that you PM'ed me, and now I can't find the email notification or the PMs on the site. Forgive me for being unfortunately new at this. I will get back to you bud, and thank you again.

Google Pixel QUSB_BULK_CID:xxxx SN:xxxxxxxx

Something happened to my Google Pixel this morning. Everything was fine last night, woke up this morning and the phone won't turn on or reboot. Power button isn't responsive, Power button + Volume down to get into recovery mode is also not responsive. When I connect my phone to my PC I also get QUSB_BULK_CID:xxxx SN:xxxxxxxx.
I did some searching around, and it sounds like the phone might be stuck in Emergency Download Mode (EDL)? Anyone has a solution on how to fix this issue?
(I can't locate the firehose (.mdn of .elf?) files to complete the steps in this guide: https://forum.xda-developers.com/t/guide-how-to-return-to-stock-flash-images-with-qfil.3901510/.)
BTW mine is Google Pixel 3,
Anyone has the solution !! Please help !!!​

Have you tired holding volume up + power together for more than 10 seconds?
That's a hard shut off, should get you out of whatever mode you're in.

Yeah, but nothing happened! Its EDL mode.

If you can't find a way of getting out of it then it says you should file a warranty claim and get a replacement phone.

Thanks for the reply...
I already did all of this but couldn't get the phone out of Emergency Mode,
and I already said (I can't locate the firehose (.mdn of .elf?) files to complete the steps in this guide and I'm not able to locate the QSPT Flashable Firmware File for my device Pixel 3.
It's very frustrating to saw that even a pixel phone has to go through this...
It was not rooted / not Bootloader unlocked / or any kind of modification wasn't done with it only an OTA update from Google was installed last wk.

Have you had the phone long? Can you make a warranty claim?
Seems as though mdn and elf files are used by the android Web installer, so maybe try flashing to stock from the Google Web installer website.
Failing that you would have to open it to disconnect the battery, that would fix your problem.

Can you disconnect the cable and just let it run out of juice?

Give your information to this proposed lawsuit this office may pursue.
Google Pixel 3 Class Action Investigation - Chimicles Schwartz Kriner & Donaldson-Smith LLP
chimicles.com

When your device appears like this on your PC, it means it's stuck in QPST mode - Qualcomm Product Support Tool. The software is not freely available from Qualcomm, nor are the necessary files that would be required to reprogram the PROM.
Some users have had success leaving their phone to run out of battery. Failing that, there is unfortunately no way to recover the device beyond seeking repair.
