[Q] AT&T LG G2 won't boot - G2 Q&A, Help & Troubleshooting

I've been messing around with my phone, trying to flash CWM and CyanogenMod (to no avail), and yesterday something happened. I woke up, my phone was dead so I started charging it. It booted into the Stock OS (the one that ships with the G2--build D20010o I think). Shortly after, a message appeared on the screen about an update the phone was going to install (I'm assuming one that AT&T was pushing to my phone), and shortly after it powered down on its own. I have not been able to get it to boot into the OS since.
Before all of this happened, I rooted the phone with IORoot, tried to flash CWM (I think successfully), but was not able to install CyanogenMod, so I flashed an earlier build of the stock OS (D20010o), rooted it again (I'm not sure that I had to--I think it stated that my phone was already rooted), tried to flash CWM again (unsuccessfully this time), and I gave up. Then this problem occurred.
Every time I try to power on the phone, the LG logo flashes, and the screen stays on, but it's black. If I try to do a factory reset via the hardware buttons, I am able to see that screen, but as soon as I follow the instructions of pressing the power button twice, it says that it's initializing the reset, but then the phone's screen goes black again--not sure if the screen is on or off, though. The LED light is also not on during any of this.
I'm unsure what to do. I've had the phone for about 6 months, but I had not owned an Android before that--iPhone user for 3 years. I obviously did not do enough research or ask enough questions, but I would like my phone to be in a usable state. I would greatly appreciate any help that anyone can give me!

NEVER take an OTA with a recovery.
Use the lg flash tool to go back to stock

Sorry, should have also mentioned that I can't boot into Download Mode. I'm assuming there's no .kdz file for AT&T, and the other method in that link requires Download Mode. :/

Emergency help; Stuck at LG logo

Solved!
Please buy hyelton a beer or a damn new phone. He's a hero.
This worked: http://forum.xda-developers.com/showthread.php?t=2432476&highlight=decrypt
Hey guys, but of an emergency here...
I'm stuck at the LG logo after flashing the Pacman ROM with the latest unofficial CWM, and it seems to have failed at Formatting system. All four touch buttons on the bottom were blue, as if they had been pressed and highlighted. No response from anything.
Reboot. Then it got stuck on the LG logo. I can't access CWM anymore, holding power + vol down does nothing, I just go back to the logo. I'm running a D802.
This was a pretty standard flash for me, I have done this many times, so I was confident in it, but now have no way back into a phone I desperately need within hours.
Process went as follows;
Full wipe, format, initialize install, it failed/crashed/whatever, rebooted, now stuck on logo, unable to access CWM, and obviously unable to access ROM.
USB Debugging was on, but as the ROM doesn't exist anymore, not sure how much help that'll be.
I'll gladly go back to either CWM or TWRP, as well as stock ROM or whatever. I can sort all that out later, right now just need things back in running order.
Edit1: I can't even turn it off. It simply boots up again, so now also worried of damaging display or battery.
Edit2: It's not showing after entering "adb devices". List is empty.
ANY help appreciated.
I'm running Windows 8, and no, I will not be able to reinstall to W7 or Ubuntu.
Thank you

[Q] Bricked? (VS980, bootloop)

Short version: Phone is boot looping at LG logo and when I try to volDown+power into recovery it gets to the factory reset prompt and I press power twice but nothing ever loads and the backlight just stays on. I'm guessing I no longer have a functioning download mode either because of the way these flashable bootstack zips we've been using on the VS980 ROMs mention that they disable download mode, so I probably can't use LG Flash Tool either. Bricked?
I had been on CloudyRom 1.3. I switched back to xdabbeb's VS980 ROM, the newest version with the 25B bootstack. As many people ran in to, for some reason after coming off of Cloudy, KnockOn doesn't work on other ROMs. I had tried to do this hidden menu trick to update the touch screen firmware which some people reported got the KnockOn working again. Long story short I was having trouble getting the hidden menu trick working while on the xdabbeb ROM, I went back to Cloudy ROM and tried to do it but that didn't fix it either. I saw people having success by going back to a purely stock ROM and doing the hidden menu trick from there.
Here is where I probably messed up, I had a backup from April of this year that I didn't have labelled/named well but I was certain it matched up with the last time I had probably been on a purely stock ROM when the VS980 finally got KK earlier this year, a backup I had made for the convenience of ever having to return to stock. I tried to restore this and that's where the trouble happened. At the time I figured worst case scenario would be that the baseband wouldn't match up and I wouldn't get a signal, but in hindsight I'm guessing it wasn't safe to try to restore this after updating to different bootstacks. Original KitKat rom was 24a I believe but I had just recently updated to 25B to use the newest xdabbeb ROM.
I saw a small ray of hope when I calmed down enough to remember the voldown+power sequence to get into recovery, but after reaching the factory reset prompt and pressing power twice to continue, nothing ever loads and the backlight just stays on, like my recovery is gone now too I guess.
And in a comedy of errors I'm guessing I no longer have a download mode that would allow me to use the LG Flash Tool through PC because these flashable bootstack files always mention that they disable download mode and I never worried about restoring it.
So, bootloop, can't get into recovery, probably can't get into download mode to work with LG Flash Tool.
Screwed? :crying: :crying: :crying:
Yeah, volUP + plug into PC just gets me fastboot mode.
Don't really understand why my recovery is gone, thought the button sequence to get back into recovery was the safety net to this entire thing and why I wasn't too worried. Was running TWRP.
I'm at the mercy of checking the internet when I have access to another computer because my phone was also my internet access on my home PC. Hoping someone can help. : (

Stuck in BootLoop and Factory Wiping doesn't actually wipe anything

Nexus 7 (2012)
4.4.4 Stock
KTU84P
HW Version - ER3
Bootloader Version - 4.23
Locked Bootloader
Not Rooted
I have a Nexus 7 sitting in front of me that was dropped off by my aunt in hopes that I could repair it for her. It doesn't look too promising, but I thought I'd consult the mighty fine people here on XDA before I give her the bad news. Here's what she says happened. Yesterday, while preforming day to day activities on it (browsing internet, Skyping, Facebook, etc), the device completely froze. After holding down the Power Button and forcing it to shutdown, she booted it back up. Everything seemed to functioned properly for about 30s - 1min when, at that time, the device turned off and rebooted on its own. After booting back up, it started to repeat this cycle. Basically getting stuck in a bootloop. I personally have never witnessed a bootloop like this before, where the device successfully boots up completely into the OS before turning off and repeating. I'm more used to dealing with ones where it might go as far as the manufacturer logo and then repeats. So anway, as I stated, I only have a 30s - 1min window where I can make changes in order to troubleshoot. The first thing I figured I should do was to go into "About Device", turn Developer Mode on and get USB Debugging enabled. I was able to do this and used "adb devices" to confirm its connection to my computer before it looped again. After its next bootloop I headed back into settings because I wanted to take note of the Android version she was running. As I was navigating there, I noticed that the Developer Options were no longer active. Basically as if I hadn't enabled them yet. This made me start thinking that changes being made on the device weren't sticking. I decided to make a few visual changes to the home screen and see if they were still there after the next bootloop. I uninstalled an app, rearranged icon placement, and changed the wallpaper. Once it shutdown and booted back up again, everything was back to the way it was before the changes had been made. The app I had uninstalled was still there, the wallpaper reverted back, and the icons were back in their original location. At this point I decided to see if I could reboot into Safe Mode. Unfortunately, this doesn't work. I am able to get the reboot to Safe Mode confirmation box and tap "Ok" but it remains in Normal mode when it boots back up. I eventually tried to boot into recovery and preform a Factory Reset. I was able to get into recovery and reset the Nexus. Or so I thought. Instead of seeing a Device Setup screen after it wiped, like I assumed I would, it booted up and still had all the data on it. There were no errors during the wipe and it was confirmed with "Data wipe complete." afterwards.
I am absolutely lost. I've never dealt with such an unusual issue before. Especially with it not even reacting to a complete data wipe. So, just to recap . . . I only have 30s - 1min available to interact with the OS before it reboots itself, any changes made during that time don't stick, Device is successful booting into Stock Recovery, and I can successfully get a Fastboot connection when booting to the Bootloader.
Luckily she has come to terms that this might not get fixed and has decided to go a head an order a newer 2013 model. I'd still like to try any solutions that you all might have. Just in case there is a slight glimmer of hope.
Oh, and one last thing I should mention. I tried to see if I could get the bootloader unlocked but it didn't work. This is the first Nexus I've ever had in my possesion, so I'm not really familiar with the tools available for it. I found WugFresh's Root Toolkit and attempted to Unlock with it. The process seemed to go as it should and I didn't receive any errors on the tablet or in the software. However, in the end, it didn't make any changes to the bootloader.
same problem
I have the same problem as you.
Did you find a solution?
Can anybody help us?
Thanks.
I have a similar problem, but I think mine is related to the bootloader.
I'm stuck on 3.34 and that's where it fails ever time I try Wug's Nexus Tool Kit.
Have you tried Nexus Tool Kit yet?

I have tried factory reset from recovery, no errors while wiping but when device restarts nothing has happened: I only have a 30s-1min of old system with all my data and apps or directly bootloop.
Also I have tried flash factory images with Nexus Tool Kit and directly from bootloader. No errors while flashing, apparently has flashed new image system. When device restarts nothing has happened: bootloop or my old system with data and apps for 30s before restart.
Myself and a few others are having the same problem... please keep us updated if you find anything out.

LG G2 Might be bricked, not sure.

Hello, cutting to the chase
Model: LG G2 D802
Story time: I tried to install ressurection remix rom through the sideload, after fully wiping my phone ( Wiped system, data, yada yada ) it showed some kind of an error about SU not installing properly, I thought well if I'll reboot TWRP will automaticly install SU for me, so when I tried to reboot it showed that No OS is installed, I thought it's a simple bug so I'll reboot to recovery again to check and bam. Nothing works.
+ Can't boot into recovery ( Tried volume down + power button ) LG Logo shows up and goes blank again ( Note that the screen doesn't turn off, just stays black, after holding it for a couple of seconds I can see screen going off completely but can't turn it on)
+ Can't turn it on normally.
+ Can't boot into download mode.
+After plugging it into an USB it mounts a D lettered drive with 63MB stuff in a folder called image with *.mdt files, modem files( I can screen it if it's important )
I'm clueless, never happened to me even though I flashed a lot of roms, I think I bricked it. Help?
UPDATE: I managed to quickly release Volume Down And Power buttons when LG appeared for half a second and hold it again, succesfully booted into TWRP. I haven't bricked it I think. Will tell how it goes <3
Hey man, how'd it go?
I'm in exactly the same situation as yours, can boot into twrp but nothing else works, i fear of the qhsusb_bulk brick but these people don't even seem to have recovery.
Any suggestions? Go back to stock? How?

Hey there, can you specify what you did exactly or where to find!? Do you mean something like this? (can't post outside links, in XDA-forum, title is "LG G2 is UNBRICKABLE NOW! [FIX REAL HARD BRICK]") Thanks for help...
Yes thats it. Lol i still got the files on my pc for my g2 i keep the whe setup cause im on the g3 now i just check in the g2 forums cause i had mine for 2 years and modded the crap outa it but yea i keep all the files on hand so if anything ever happens i can fix it almost on the fly now
Well so what happened to me that I managed to get inside the TWRP. When it lighed it up for a second I quickly released and held again that got me inside magically. So then I just transfered new rom and tried to install again. Sadly I didin't see that the ROM Im trying to install requires bump TWRP and I bricked my phone again. Though I entered download mode and flashed the stock rom through LG G2 flasher.
heres a video i made, how to go into recovery. for those that cant get in to twrp.

Please help! Soft bricked, unrooted, untouched, 100% stock phone brick during update

I am in need of serious help! I dropped my phone off a 2nd story, smashed the screen completely. So I took my wife's old stylo 2 plus (exact same phone) stuck my Sim and SD into it, registered through metro pcs, and it worked great.
I did software update because I was really excited (my old stylo 2 was rooted and had many problems along with being unable to update android software).
Update took about an hour, then said failed. After that it has been unable to boot up. I tried recovery mode, it offers to factory reset. Again reboots and stuck at logo screen. Says error device is corrupt, cannot be trusted, will not boot. I press power it says press power again to boot anyway. Restarts and sticks at logo screen. Device is basically untouched. No oem unlock, no debugging, no developer options, nothing has been touched ever, the phone is 100% stock. I even did factory reset before I started using the phone.
Can someone please help me at the least flash trip so I can fix this??
I am not new to this, but has been 5 years since I flashed anything. The problem is, is that it's still locked, and can't boot up. The phones bricked and never been touched!
If I can get twrp flashed I can go from there, I need a way to unlock it, or flash without unlocking.
Please help me I need my phone for work. I'd rather not switch back to an old smashed screen

You need to download the kdz(device firmware) and flash it in download mode using lg up.
Sorry for the super long delay. I did what you said, and was able to use my phone again in no time. Thank you very much!
