Need help restoring / un-bricking Verizon G2 - G2 Q&A, Help & Troubleshooting

The perfect storm...
I broke my phone about a month ago, bought a hold over on craigslist until I fixed my phone. Left the phone stock and yesterday sold it to a truck driver via craigslsit. I did a factory reset handed over all good to go. He is now out of town
This morning he calls me and says the phone is locked in TWRP and is politely upset. Confirmed the phone worked when I gave it to him. I did not install or root this phone so the crap ass before me must have and did it and not mention it. The guy has no clue what happened, went to bed fine, woke up and stuck looping in recovery.
I tried to walk him through it. Reboot, says it lands right back at TWRP. He seems up to the idea of using a tool or utility to flash it.
I found this thread [Guide] Unroot/Unbrick - flash official factory firmware with LG Mobile Support Tool but it does not seem to cover the Verizon variant.
Can anyone point me to some instructions I can send this guy on getting this thing back to stock?

Recovery failed - need help please

I tried to update trwp from 2.7 to 2.8.0.1 with safestrap. I don't know what I was thinking. Now the phone will not boot. It says secure fail:recovery, them something about system software not authorized by verizon.. I am trying to find a way to reload safestrap to the phone without having to start from scratch. Please help. Note 3 retail, rooted.
Update: after staying up all night doing everything I could think of to no avail, I took the phone to a Verizon store. I made up some **** and bull story and the guy took my phone in back. He came back a few minutes later with a big grin. He had fixed it, and everything was intact. When the phone rebooted he saw the safestrap and smiled at me knowingly, but not a word was said. I need to stop screwing with my phone late and night when I'm tired. Lesson learned.

[D802] Have I hard-bricked my phone?

My headphone jack was broken so I called my insurer and got a repair scheduled. Before sending it in, I wanted to reset to stock for them. Afterwards, I'd flash a new ROM. I was running Mahdi from August 28th 2014. It was about time to restart fresh. Now, I downloaded the KDZ for my IMEI, which was D80220H. The last one I used before that was D80220F. Loaded up my flash tool, went to town. About 30% in it reported an error and quit. The app adviced me to reboot the phone, so I did. That's how I got where I am now. Phone does boot, but after the LG logo it goes into a black screen and shows up in device manager as QHSUSB_BULK. I've tried the guide for this, replaced all the partitions with the images from the D80220H KDZ, but it hasn't changed a thing. What can I try to get it working again? I've heard people say this phone is unbrickable, so I hope I'm not lost yet.

Help! Help! Help! Please!

Bought a OTG from China, used one, left plugged into the phone as I slept...don't know if it's the cause of my troubles to start happening, or if the Twitter app I installed at the same time is the cause.
The phone became TROUBLE and I eventually decided to try going back to stock. I did manage to get stock on but couldn't use because the phone immediately would display the dreaded "Unfortunately.......", which pops up so often that you cannot do anything. So I decided to do a full wipe from factory recovery. Since then, the phone wont power on at all! I have left it to charge overnight, all day, NO POWER!!!! I have read many similar accounts. I lost as what to do! I had ZERO power issuses before. Saw a vid where a guy says the power switch is faulty. He ordered one from eBay and replaced it. 1) I don't think it's the case. 2) don't think I wanna try soldering, etc.
Any help would be appreciated!!!
I have the 910W8 from Rogers in Canada. ODIN flashed with no problems (used the latest firmware from sammobiles for my phone) but would get that error after the flash, causing it to be unuseable. I flashed a second time and same thing. That's when I decided to do a wipe from recovery. Now it won't boot up.
Wow! NOBODY?!

Cannot believe nobody has replied. I did get one of the usb things from a very nice member (i have to register myself as someone who now has one) but the phone is still not working.
Having done some confusing reading to try to fix mine but don't think i can.
Wondering if there's a good, reliable, store in the GTA (north end preferrably) that can do repair with JTAG? Wondering if there's any hope in recovering this phone. I get the impression that there's a good chance JTAG repair can bring it back to life.

note 4 (N910A) verity error after stock ota update from 5.1.1 to 6.0.1

Hey guys,
I could use your expertise and help.
After updating my stock Note 4 Att variant from 5.1.1. to 6.0.1, I came back to my phone powered off. After turning it back on it freezes at the Att logo screen. Trying to boot into safe mode was a no go so I tried booting into recovery. Everything looked go for a second, I was greeted with an installing updates animation but that quickly was shut down and I got the "dm-verity verification failed..." error.
I tried wiping the cache and doing a factory reset. Talking with att technical support was no help at all. They basically told me if wiping the cache and factory reset didn't work I would have to get the phone replaced and pay a $150 deductible. I'm not paying them another dime when their update bricked my phone
So I'm here heart in hand hoping you guys could help me out. I did root my note 2 back in the day but forgot most of what it entails and was pretty bummed when I found out there was no root for the note 4. So I'm not a total noob but bear with me.
I did try Kies 3 but my phone wont connect. I tried off, on and in recovery still nothing.
Searching online it seems like most of the solutions require root access which this phone doesn't have. It also looks like it needs the stock firmware but most of the links I found here and elsewhere are dead, and sammobile doesn't have them either.
So what should I do? Am I out of options? Should I junk it cause Att sucks? Any sort of direction would be a big help! :highfive:

Make sure samsung kies or samsung usb drivers are installed on your pc.
Download stock marshmallow firmware and flash through odin .this method does not require root.
After flashing dont let the phone boot just go to recovery and wipe cache+wipe data factory reset then reboot.
Wait 10 to 15 minutes.
Stock rom link.
https://www.androidfilehost.com/?fid=24651430732238073
Extract file and choose AP tab in odin.
Upload firmware file then connct device via usb cable to pc.
Hit start in odin.
You're the man! Not only did you save my phone, you stuck it to Att's money grubbing hands in one fell swoop. People will write songs about you, you'll go down in the history books as the man, the myth, the legend! People will swoon in your presence!
In all seriousness though you're awesome! Thank you!
One last question, will I be able to use the ota updates from here? Not that I would be too comfortable using them after this debacle, just wondering if they should work.

Thanks for the compliment. you just made me feel like i am a Hercules :victory:
If you want my advice dont ever take ota updates.
Just go to www.sammobiles.com/firmwares and grab latest rom for your model and flash in odin as you did.
Latest rom comes with the same security patch update the 1 comes in ota.
I personally do this way all the time.
Hope that helps and have a good day.

LG V20 6505A (AT&T) Firmware Update 910K B50

Hi all. Trying to recover my fathers old phone here and stuck in the firmware update do not unplug usb connection until process is complete, but has been stuck at 0%.
Back years ago, he was trying to do a regular install of an update from AT&T, something happened, and got stuck in the bootloop. AT&T didnt want to help and sold him a new phone.
We got into a fierce argument about the phone, if it can be fixed or at least traded in. Well, he died two weeks ago, and now I am trying to work with that phone, get it working, then trade it in, along with his S9+ for a newer model.
Any suggestions. Was never rooted. I can get to download mode, but nothing happens after that.

We are kinda stuck because there is no firmware for the H910 no kdz file you can flash. You can try a factory reset on the phone.
How to factory reset the Lgv20
This will wipe all data on the phone. Let me know if that works.
