Restoring A LG G2 VS980 From Verizon Back To Stock? - Android Q&A, Help & Troubleshooting

So I'm trying to help a friend fix his G2. It's a VS 980 that uses 12b software (I have the kdz file downloaded) for this phone. The problem is I've looked at tutorials on this website and none of them have helped me thus far. With the LG Reflash tool they allow you to choose a USB driver for your device which goes up to VS910 but not vs980.
When you boot the device it just says fastboot mode started ubc.start() fastboot processing commands.
I believe my friend told me too that he removed basically everything from the phone to try and reflash the default stock ROM. What are the options what should I Do?

It gets worse. So I've tried re-flashing the phone and I've gotten nowhere. No it's so bad that the phone won't turn on at all EVEN INTO FASTBOOT, but instead just has a red blinking light.
This is also unnerving since I have the same phone and I'm starting to think Verizon never wants you to restore this if there's ever a problem. Probably so they can get more money and bring your phone in and get an early upgrade.

[Q] HELP! Photon wont boot! (Stuck at red M)

So yesterday I was in a call with low battery when it shut off. Normally not a problem, just plug it into the wall for a while. Well when I tried to turn it on, it wouldn't even boot up. It was stuck at the red M logo. The LED showed amber colored as well. I left it plugged in and the light remained amber until 90% battery, where it turned green.
I tried to turn it on and its been stuck on the red M logo. Its been stuck for more than 12 hours now.
I CAN access fastboot, android recovery, etc. I already tried wiping the cache and even did a factory reset. Still wont work.
What can I possibly do? I luckily have a backup phone, but I've had my photon for less than a month, no warranty, and I'm a novice Android user. Any help would be greatly appreciated.

Click on the software and tools link and use rsd lite to reflash the stock os onto the phone. If that doesn't work I would take it to the sprint store.
I assume you tried pulling the battery?
I'm downloading SBF now. Hopefully it works, because I live in Canada and we don't have Sprint stores.
And YES, I tried pulling the battery. Multiple times. With every combination (eg, plug in, turn on, then insert battery; put in battery, turn on, then plug in, etc)
the sbf should work but may i ask how you managed to brick your photon? when i just got mine i did everything wrong and i never got even a soft brick so i'm interested what i didn't mess up haha
Quick question: I should be downloading the most recent? Will it make a difference?
And damn, did I actually brick it?? I'm pretty new to this thing, this is my first Android and I've had it for less than a month...
And nothing should have triggered it. I added another line in build (ro.media.setting.1080p or something) and I added another setting in /system/etc/mediaprofiles.xml. I was trying to add 1080p to the camera (unsuccessfully). I didn't remove anything, and even after a reboot it was fine.
It wasn't until the battery died, where it stopped booting up. Just my luck :/
You should probably choose one of the newer ones, just becasue of bug fixes, etc. If you happen to know what version you were running before then I'd choose that. I cant stress enough, make sure the one you download is for the Photon and NOT Electrify! And technically yeah that is a brick lol but its extremely hard to legit brick beyond repair a photon due to the fact that we have RSD Lite and SBF files to bring it back.
Strangely, I found a thread depicting the same problem that I had, although with the electrify. http://forum.xda-developers.com/showthread.php?t=14813
Anyways, the problem is fixed, by reflashing the SBF using RSD Lite, everything is back to normal! Well, almost, just have to restore my backup
Thanks so much for your help guys, I wouldn't have been able to fix it without you all!
can you fix a bricked phone??
My Photon has done the same thing! I rooted her and did the Bootstrap Recovery thing. Everything was kosher until I tried to load that stupid Beats Audio. Something happened between me flashing it and the reboot where it locks the phone. I tried to do the Android recovery screen, I wiped, I did about everything I could find. No bueno.
I followed this forum and clicked the software and tools link as instructed. I tried with RSD 5.6, and tried several iterations of SBF's located here and here. I was using SBF - 1FF-sunfire-user-2.3.4-4.5.1A-1_SUN-154_MR-3-CM.
It lets me go into boot mode, and when I try to flash the SBF it appears to go through, but it always fails at the end. Which, the posts state it will do, but my phone will not reboot afterwords. After trying everything I could for a couple days, I decided to just take it to a Sprint store. Mind you I've had this under 30 days, but longer than 14 so they stated it would have to be replaced. They tried to flash, but said they were getting stuck too.
I know that a replacement is pretty much the answer, but just wanted to check one more time to see if anyone had any other ideas, or could point me to other forums maybe? Appears I've done what few have been able to accomplish...brick this joker.

[Q] Bricked Rooted LG G2 After OTA, No Download Mode

I have the D-800 AT&T LG G2, It was rooted with KitKat 4.4.2. After I rooted my phone, I tried several different ways to install TWRP onto it. I tried FreeGee, adb shell, and straight from TWRP App, nothing worked, because when I tried to boot into TWRP it would just come up with the LG Logo and "Secure Boot Error" and "Certification Error" or something like that, then be a blank screen. I then just held the power button to turn it off, and it would turn back on and run fine, no problem. I figured it never installed right, and so I left TWRP alone. I know you are not supposed to take an OTA after install TWRP, but thinking TWRP never installed on the phone, I took the OTA, and now it will do the "Error" messages and blank screen, but my power off, power on trick doesn't work anymore. I can boot into Recovery Mode, but when I do a Factory Reset, the screen just goes blank. I have tried to put it into Download Mode by pressing Volume Up + Power when hooked up to a PC, but nothing happens. I feel as though its a tough brick. Please Help!

I could not find a fix for this problem. Instead, I sent it back saying that it updated automatically and then it didn't work. They can not tell that you have rooted it, because it is so messed up, SO DONT TELL THEM THAT YOU DID! It'll take about 2-3 weeks foe it to be sent back. It'll be free as long as you are under warranty. Just talk to a customer service person on LGs Online Customer Service people. I hope this helps you out!

Thanks For The Suggestion. Ironically, I Was Just At The AT&T Store Because They Were Selling Otterbox Defenders For 25 Bucks, And I Told The Guy That My Phone Was Rooted. I'll Have To Go To Another Store. I'm Working On The Linux Fix As We Speak, So Hopefully I Wont Have To Send It In.

I have tried the Linux fix, that didn't work for me, hope it works out for you. Talk to LG, they are the ones who will fix it. You will have to send it to them. I used United States Postal Service, it costed me like 9 dollars, which isn't bad. Good Luck!

Phone Keeps Dying

I was using my phone normally tonight and it keeps rebooting spontaneously. Sometimes it makes it back into the system, sometimes it doesn't even get that far. I do have it rooted with TWRP and I can get into recovery. I cleared cache/davlik cache and during one bootup, it make it as far as optimizing apps, but rebooted again about 10 apps in.
I'm currently on xdabbeb's 46A.
I can get into TWRP by holding down power/volume down where I get to a grey system recovery screen. I then choose the wipe cache option and then it gets me into TWRP.
I'm in TWRP and trying to flash xdabbeb's 47a and the phone screen just goes off in the middle of the flash and I need to do a battery pull to get it back. It dies at different points along the way in the flash each time I try. Temp is only around 66C last time it crashed.
Any chance flashing to something old fixes this? Doesn't seem like that would help any considering that it's dying in TWRP. Sure seems like a hardware issue to me if it's crashing in TWRP, no?
Any suggestions at this point? Please Help!
I figured at this point, why not, and I'm trying to .kdz to 12b. I ran the update tool and I got the connection to server failed error, but clicked through it and I've got the upgrading your phone box, but the time elapsed isn't counting up. On my phone, I've got a green COM3, progress indicator at 0% and then in the box below it says some stuff with the last 2 lines being
VS98547A
VS98512B
After a bit, the text on the screen gets garbled all over (same thing happens in TWRP) and then the screen goes blank and I guess the phone is off at that point after a few seconds more, the LG Flash tool says upgrade stopped due to an error.
At this point, I can't get into TWRP anymore, just the firmware update screen. I guess I'll leave everything unplugged and try again in the am, but not very hopeful.
I think I'm screwed with a bad phone.
Any other ideas here?
Seems like the longer I keep the battery out, the longer it works before it dies again. Almost like it keeps overheating, but the phone certainly doesn't feel hot nor is it doing anything strenuous right before it dies.
I really don't see how this isn't obviously a hardware failure, but I also now that it's relatively rare that hardware just flat out fails. But, with what I'm seeing it crashing in recovery and download mode, I don't see how it's software.
I was able to kdz to 12b, but same thing happens. After a little while, it just freezes and turns off.
No improvement leaving phone without the battery overnight. Booted up on 12b clean and rebooted maybe a minute in. Got back into 12b and then it froze and powered off.
Don't see how this isn't hardware failure.
Anyone have any thoughts?
Do you have an aftermarket battery? Crazy stuff can happen with some of them, though that sounds like a long shot with your symptoms. Inspect battery terminals for corrosion/damage also. Sure sounds like a hardware failure to me too though. Especially when you mention the screen tearing/artifacts even in TWRP. There's been some G3 problems where the screen will flicker and fade to black, this sounds similar. The fix (or temp fix?) for that was shimming the camera connector on the motherboard, and/or baking the motherboard to reflow cold/weak solder joints. http://forums.androidcentral.com/lg...y-lg-g3-screen-flicker-fades-darkness-13.html
If it gets to a point where you try a reflow, consider adding a thermal pad to the CPU when you reassemble it. http://forum.xda-developers.com/lg-g3/general/experimenting-hardware-mod-t2845220
I was recently having all sorts of weird issues no matter what KDZ I flashed. It wasn't until I flashed the 10B TOT (TOTs flash more than KDZs do) that the problems went away.

Weird issues as in the phone just turning off or rebooting a few seconds after the OS loads as well as tearing on the screen (saw that both in download mode and in TWRP)? I'm getting the green screen every so often too.
Ok, I guess I'll give that a shot, but I'd be stunned if this wasn't a flat out hardware issue.
Took me a few tries to even flash 12B kdz before the phone stayed on long enough to complete.

No, I was having different weird issues, but that doesn't mean the solution isn't the same. Obviously, I can't know that's the solution - just that if you were able to eventually get it to flash a KDZ and that didn't solve it, it's worth trying the 10B TOT. There are other partitions not flashed with KDZs. If any of them got corrupted (as mine must have somehow), only the TOT will restore them.
I'm not betting either way what your results will be.

I'll give it a shot and post back. At least it's good practice on how to TOT if the new phone comes with 35B or newer.

Doesn't seem like I can even keep the phone on long enough to get the TOT to download. I get the yellow Ready in LG FLash tool after I click start, but waited a while there and nothing happened. Before anything ever started downloading to the phone, the phone crashed. Hard to keep it on long enough even to get it into download mode now. Seems like it was on for a while after the first time I put it on this afternoon after I hadn't used it all day. Like it seems like it's a heat issue, but the phone isn't hot.

When you get the yellow Ready, you're supposed to unplug the phone for a second and then replug it in, then after a moment it'll continue.

Yes, figured that out with the new phone. But, with the old phone, I couldn't even get it to not crash long enough to get to that point. Maybe once I got a little past that before it did.
I don't see how it's not a hardware problem if it's just turning itself off in download mode.
New phone works great and was relatively cheap and came in decent enough condition.

Softbrick? Or am I out of luck?

Hi I'm pretty new to rooting and flashing and all that modifying my phone stuff. Firstly I'd like to thank @roirraW "edor" ehT and @LASERWOLF452 for the guides on rooting my phone which I've been trying to do for over a year, but just now finally succeeded.
Now I've run into a problem leaving my phone useless. Not sure if software or hardware problem. After I turn my phone on, which sometimes that doesn't work, it gets to LG logo then screen goes black, all buttons unresponsive including power button. I think I softbricked my phone because sometimes it gets stuck in the bootloop. (Edit: It doesn't go into the bootloop that often, mostly just blackscreens after LG logo or when I turn it on, it vibrates and that's all, logo doesn't even pop up.) Sometimes when I pull the battery out, wait a few minutes, then put it back in I can get it to turn on and get to the PB Screen after the LG logo (because I have the PitchBlack theme installed). Sometimes I can even get to my home screen even open an app, but then everything freezes and screen goes off. Usually after any of these attempts, doing anything with the power button results in nothing, not even a single vibration. It makes me think that the phone is on just the screen is unresponsive. So I have to pull the battery out and try again. I held volume down and power button til LG logo came on, then let go of power button and immediately held it again until I got into recovery. Scrolled down to factory reset, clicked yes, then most of the time the phone shuts off and the LG logo comes on and goes black again. One time it got TWRP to open up. But it froze and screen went black. I finally got it to go into TWRP again randomly, but trying to click on the "Advanced" key in the process of wiping the dalvik cache my phone half froze. By half froze I mean just that. The status bar showed my phone's changing temperature, the minutes were changing and the battery percent showed. When I went to slide the arrow to wipe the cache it wouldn't move. It was like the bottom part of my touchscreen wasn't working. Then I pressed the power button and it locked the screen and said slide to unlock but I couldn't slide the slider. So it's like half of my phone functioned and half didn't.
I wasn't having major issues like this except occasionally getting my phone to receive a charge or turn on. This booting issue started yesterday when I was at work. I was just playing pokemon GO and decided to charge my phone. I unplugged a charger for a Bose speaker (one of those color sound ones) and plugged it into my phone and it immediately shut off and wouldn't get past the LG logo. After a long night of failed attempts to get it working, this is where I am now.
I rooted my phone last week. After the first night I freaked out because I couldn't get my phone to turn on the next morning, I forgot to charge it and the battery was drained. It wouldn't even receive a charge. Then I googled some stuff and found out that taking the battery out and putting it back in can sometimes get it to receive a charge. Then I have to unplug it before turning it on or else it'll just reboot with the battery logo. I've had to do this every time when the battery is completely drained.
I rooted my phone by downgrading to 35B and doing all that LG FlashTool stuff then used Stump. Then installed TWRP and CM13. The most recent thing I have been messing with is Xposed Installer and downloaded and activated a few modules yesterday. Could those have done something? A few were out of date that I decided to give a try. After I turn my phone on and feel it vibrate and all that, I think it actually is turning on. Whether it makes it to the LG logo or not, it seems like it is turning on and maybe the screen just isn't functioning the way it's supposed to. I can't turn it on again, holding the power button does nothing.
Sorry that this was really long, tried to give a detailed description of my issue. Phone has been useless for 24 hours now. It really sucks because I need it, will be traveling through a few airports later today and need to call people to make sure I have rides. Only thing I can think to try is get a new battery. I would really appreciate any help that anyone can provide! I'm desperate.
Update: Recently I have been able to get the phone to start up like normal and get to the home screen, check my texts, that kind of stuff, but within 30 seconds it freezes and shuts off.
I'll confess, I didn't read everything, but a few questions and suggestions. FYI if it were me I'd skip right to suggestion #3.
Can you still access TWRP?
If so,
1. Try wiping Cache and Dalvik /ART or if that doesn't work wipe Cache, Dalvik /ART and Data.
2. If both don't help, wipe them again, then do a fresh flash of whatever preferably stock based ROM you want and the appropriate Bootstack.
3. I would flash the 10B TOT and start fresh. It's often enough the experience of users who flash non-stock or international stock-based ROMs to have various troubles.
No matter what caused the problem, TOTs contain more partitions that KDZs and flashing TOTs can fix problems that KDZs can't.
Good luck, keep us posted.

Sorry I know it was super lengthy. Sometimes I can access TWRP and sometimes I can't. I'm getting so aggravated with my phone! I think I successfully wiped Dalvik which did not help so I'll try to do the others if my phone wants to cooperate with me. Most of the time it doesn't even want to boot into recovery. Most of the time after clicking Yes under factory data reset the LG logo pops up then my phone just goes black.
Update: Wiped Davlik/Art, Cache, and Data. Rebooted and saw the CM13 logo instead of PB but then immediately shut down.
Yeah, I'd definitely go the 10B TOT route.
I've rooted a few phones, but I'm not a ninja like these other xda'ers are. I'm running Jasminerom 8.0 (which is excellent on the g3), a couple of weeks ago, I tried Dirty Unicorns, but it didn't seem to play well with my phone, so I went back to JR 8.0 (by restoring my nandroid backup) then tried to upgrade to JR 9.0 then 9.1. I didn't even get the LG start screen, the screen was black, but I could tell the phone was on by a couple of noises. I did hyelton's "[Guide] LG G3 Stock Firmware (Go Back to Stock) KDZ & TOT Method With LGUP" http://forum.xda-developers.com/showthread.php?t=2785089 It puts the phone back to dead stock, you have to root again and reinstall twrp, then you can go to the rom you want. It scared me pretty good, but within a day or 2, I had my phone back to where it was. Don't forget to thank the devs who post these guides, they can get you out of almost any jam you get into.:good:

Do a battery pull to make sure it is shut off, then do the Vol up while plugging in the usb cable. Even if the screen stays black, it should still go into download mode (that's exactly what had happened to me). When you go into Device Manager, you should see LGE Modem listed under Ports, and keep following hyelton's instructions. I was sure mine was dead, but it worked fine.

I managed to get into download mode, two additional times. The first time, after started FlashTool, it said download failed at 10%.After an hour I finally got it to go into download mode again. Got to 57% then said download failed. My phone won't stay on or something. Everything was going smoothly, then boom black screen download failed. This has been the problem the entire time with my phone. Sometimes I can get to the homescreen, open my texts, browser an app or 2 then freeze and black screen. It won't stay on long enough for FlashTool so what the hell do I do now?!
Now my phone won't even vibrate when I plug it in while holding Vol Up. It comes up as something slightly different in device manager though. I kept FlashTool open even with the failed download, but it says "Can't change to download mode" in the port 1 box.
Also sometimes after plugging in, when it does vibrate, the LG logo comes on instead of DL mode. When that happens my phone appears as something QualCom in device manager then disappears.
Also, does it matter if my COM41 says 'in use'?

Now you're getting into territory that I have no experience with. I'm sorry I can't help any farther, I hope some of the more experienced xda'ers can help you out.

lol thanks for your help! The only issue I've run into the past hour is that I haven't been able to get into Download Mode. When I hold Vol Up and connect USB it either loads the LG logo or just goes blank. Doesn't give me the 'download mode' with the blue dots.
So I'm guessing it's a bad thing if my phone shows up as Qualcomm HS-USB QDLoader 9008 (COM9)?
Phone just shuts off too fast to do anything. If I successfully make it to download mode, only shows for two minutes in device manager. Qualcomm only shows up for about 2 minutes too. What do I do? I can't even flash the 10B TOT because of this.j
It used to be hard to get the battery to charge, but now I can't get it to charge at all!
Update: I realized, the longer I leave my phone alone, the longer it stays on. I waited an hour then tried Download Mode again. Phone stayed in Download Mode long enough for me to get to the blue screen and the red 3. I forgot what to do when I got to this point so I just let it go and it turned off by itself. I took out the battery, then tried to reboot and it hit the LG logo and the little Android when you first set up your phone then black screen.
Update 2: After waiting another hour, I got the phone to sort of start up. Got to the LG logo, then the green android with a blue loading bar underneath then wham! Green screen saying Tz crash! DemiGod Crash Handler. And some other stuff. What the heck is this? Never even heard of it before.
Update 3: tried to flash again, reached the blue screen with the red 3, pulled out USB and battery then tried to boot up and doesn't even boot up.
Sorry for double post, but this is a huge update. I realized the longer I leave my phone alone, the longer it will stay on. So I left the battery out for an hour. Finally I was able to flash 10B TOT and got to the blue screen with the big 3 on it. I wasn't sure what to do so I just left it there and it eventually shut itself down. Tried to boot up and same thing, black screen after LG logo. Does this mean I'm out of luck @roirraW "edor" ehT ?
Don't tell me this has been a hardware issue the whole time... I even tried new batteries today when I went to a cell phone outlet. Tested 4 LG G3 replacement batteries all with the same blackscreen after LG logo
It does sound like hardware, but its very possible the battery itself is the only issue. Unfortunately, without a spare to try, I don't know any way of finding out for sure if that's the issue without buying a new battery. LG's had them on sale for $15 from time to time, but I don't know if they are now or if they're in stock. On the one hand, I'd hate to see you buy a new one locally only to find out that doesn't fix anything but if the battery is the only issue it's a shame to write the phone off. If you lived around Columbus, Ohio I'd offer for you to try my battery just to see what happens.
There definitely has been enough of a precedent of user's batteries being the culprit with this phone.
That's what I get for reading only 5 out of 6 of the new posts. Sorry, yeah, it doesn't sound like there's much hope. Glad you at least had a place to try a different battery without buying one. I don't know what else to suggest - you could try sending it to LG for service. I can vouch for their warranty service - I can't personally report on their out of warranty. In warranty they returned my tablet fixed four days after they paid to have it packaged and shipped to them.
EDIT: Nevermind, only read part of the post and provided bad advice, lol.

The guy almost didn't let me try the battery. It was a dinky little stand in a farmers market and I was like let me see if they have any batteries. Luckily they did and I was like can I try it? He had the audacity to say sure but that's 20$ extra. Then I said how much is the battery? He said $40. THIS GUY!!! I almost had to beg just to see if it worked, and he finally agreed. He wouldn't even let me do it myself so I gave him my phone and he tried 3 different batteries and still the same problem.
I really appreciate that you would offer a stranger to test out your battery. It's funny that you live in Columbus because I actually go to school near there! I don't go to OSU but I go to OWU in Delaware, Ohio. But you are right, I'm not currently there but will be there soon.
Anyway, I decided that I had given it my all after trying different batteries, flashing the 10B TOT, etc. and made myself go to the Verizon store. Told the guy that greeted me that my phone wouldn't boot. Mind you I'm a little nervous because I don't want them to find out it's rooted if the 10B TOT didn't flash correctly, but I figured I'd had this phone for over two years, it's out of warranty so whatever. He tried to boot it and got nothing, not even the LG logo. So he said since the screen isn't cracked and no water damage I can get a new phone for free. You should have seen my face, my jaw dropped. I said "What?" He told me I have some warranty extension insurance. I said I know I had some insurance where I paid like 8$ a month, but I canceled that last year. He told me no, you have insurance and you pay 9$ a month. I was astonished and was like wow I thought I cancelled it, oh well, if it fixes my phone for "free" then let's do it. So now I'm eagerly waiting for the phone to arrive in the mail. I've had a brick for 4 days now so I'm feeling all kinds of disconnect. My only regret is that I didn't go into Verizon earlier.
So I'm hoping their warranty service is as great as you say. My only fear is that when I put my current battery, sim, and back cover on the new phone that it won't boot. I suppose at least I'll know for a fact that it's the battery at that point. Weird though that I've had this battery for two years and not a single issue...
Would it be wise to go through the root process again? I did all this in the first place just so I could cheat in pokemon, but then found so many cool modules from Xposed that made my life feel that much better.

The 35B Bootstack should allow you to use the original .DLL, because it's the correct combination of partitions from both 12B and 35B - which are necessary in order to be able to get into TWRP and as far as I'm aware allow using the old .DLL but also as far as I know and have experienced, you can use the newer .DLL any time. It's only when you're 100% stock 35B or higher that you can't flash the TOT without the newer .DLL, and can't flash KDZs older than 35B.
See post #5 of this thread for a link to a post. The post has another link to directions for Verizon. You can get the 10B TOT and the newer .DLL from my Android File Host link the bottom of the first post of @annoyingduck 's stickied return to stock thread in the General section, also in my signature below.

Demigod Crash Handler LG v10

Hi, somebody knows what to do in this situations? I am really without hope. I was texting on whatsapp and phone freeze for 5 minutes. I removed battery and try to reboot and It appeared this screen and only this screen. Cant go to recovery but I can go to download mode, I tried to refubrish some firmware with LGUP but the program give me an error. In download mode I see the phone on lg bridge but if I use lg tool flash it don't see it. I hope in some advice. Thanks
Did you try upgrade instead refurbish kdz ? Hope make alive you're mob.
i've tried all... upgrade, refurbish, upgrade fota. Always error. When I put it in the congelator fro 3-5 minutes seem better but it gave me always error, instead after a while out the congelator it wont boot up at all...

did you try lg bridge => update error recovery option. it will redownload the firmware and install freshly.
I tried and succesfull, but on reboot go on bootloop and nothing change (its disappeard green screen at least). Now I think Its a bootloop problem and so its fu**ed up. So frustrating
Well i got the same green screen and the bootloop also just some minutes ago. I can get into download mode, but my pc wont recognize the phone at all. After some time it will continue to bootloop from download mode also. After some cooling the phone boots into android, but after seconds it freezes and starts to bootloop.
Any idea what i could do with the phone to fix it? Im out of warranty, so it would cost too much to send it in to the repair shop.
same problem with me please help
How far out of warranty? LG's been taking care of people 18+ months out in some cases.
I bought my phone some 15 months ago. So i contacted LG and they offered a free check for the phone. If it is bootlooping they will try to repair it for free. If not reparable the store where i bought the phone will compensate me. Hope it all goes well.
I got this yesterday while playing a game. My sense is some thermal-related hardware failure.
My paranoid side is curious about the timing. I once had a VCR that broke THE DAY my warranty ran out. I'll update when I learn how T-Mobile deals with this, but I'm paying for insurance--so I may get a replacement (and another 15 months or so until the replacement "times out"?).
same problem here too :crying:

same here since today!!! wtf never heard about it before
same here today
It's a bootloop guys. LG will most likely give you a repair even if out of warranty, you just need proof of purchase (I bought mine online so I just sent them the confirmation email).
In Youtube there are plenty of videos that claims they have fixed the bootloop issue by applying thermal paste or pads and comments in that videos prove it shurity. I am also interested to purchase lg v10 but after seeing this kind of issues i m little bit scared
same here .yesterday using facebook and then..boom...restart....bootloop....some time starts and freezes at 5 minutes. some times green screen. i enter download mode and reinstall firmaware but same story
Hello everybody !
Anybody have solve this problem?
I have the same green screen demi god handler.:crying:
When he's connect on PC, it is in Qualcomm HS USB mode.
Help us Please.:good:
Same problem here. I think it is bootloop and as much as I know only permanent solution is to replace the motherboard. But I have a problem about it, does anyone have any idea about the models of LG v10, since it has too many models, h960A, H960AY, H960TR etc. And mine is H960A but if i replace motherboard myself, should the new motherboard also be H960A or doesn't it matter?
and here comes one more ...
Written on messenger when it hung. Restarted and displayed the logo to become green.
Luckily, the phone is 11 months old. I miss it already, especially the camera
Same here today...
