sorry to bother you all. i bricked my device and it's only a few hours old. I rooted it using the io root method. that was painless.
anyway, it didn't brick then. i got a notification from verizon for the 4.4.2 update so I clicked download update it never installed and that's when the bricking started. Anytime I connect it to the computer it opens up like 40 disks and it says cannot be used unless it's formatted so I have to spend a while canceling those out. when I restart the phone it says the lg logo then the screen goes black . im stuck. i've been trying for hours. if i get the phone back i won't root it or do anything. ill deal with the bloatware, whatever. i've tried a lot of different things but to no avail. any help is appreciated. thank you for your time...and wont go into download mode....help please anyone....
i have no recovery installed....every time i try to cut the phone off it vibrates screen goes off and on showing the lg logo very quickly then goes black but remains on until battery drains
Im in the same boat

If you can't boot into stock recovery (vol down + power key) and can't get into download mode (this is where they detect root once FW update shows up and the bottom left corner says Bootloader: ROOTED) then you can rest assure as long as you are under warranty, send it in to LG directly.
Do not send it to Verizon as you may incur charges for replacement. There's insurance from Verizon, but the real "replace with no charge" warranty is sending it to LG directly. Make an account on their website, register your G2, and make a Repair request by online chat or phone.
I just got my T-mobile G2 back after 2 weeks with the same issues and while it took a while to get repaired, I didn't pay a penny and it works without T-Mobile ever knowing its different hardware (all they replace is the flash memory that is corrupted in the phone).
Only downside is that it came back with KitKat and unrooted which means I have to wait for a working root procedure for it unlike with JB (I'm not afraid to root it again since I know what messed it up before was custom recovery TWRP version 2.6.3.2 that doesn't support KitKat lol).

Not getting into download mode is odd especially for just accepting a OTA update. Remember since they accepted the OTA its gonna take a special way of getting into download mode as the phone will be constantly on in boot loop. not all of the time but most of the time when people say they cant get into bootloader they have to keep trying due to the phone has to be "Turned off" OR rebooted at the same time of holding down the key combo.

To get the phone to turn off, one has to reboot the phone (power key for 10 seconds) while holding volume up WITHOUT having the USB cable plugged in.
Recovery mode is a bit trickier by having to hold the power key for 10 seconds, then just as the phone reboots, hold PWR + VOL DWN and while holding VOL DWN, release PWR and press it again (gets to that factory reset screen where you press PWR 3 times).
Not trying to teach you this if you already know how, just stating it if the OP looks at this then he can try again with the above.
Also, Download mode is essentially the "bootloader" and it is locked meaning unless you have certified software (KDZ FW updater), you can't adb anything just in download mode unlike some LG phones that have emergency mode which is unlocked bootloader.

ive tried
ive tried factory reset "vol down & power"...its just goes black and stays the same
I'm having about the exact same problem. I rooted my phone a while back, I left it stock and just used some modules (xposed). When I noticed the update I of course was stupid enough to hit the update... My phone is doing the same as his. I can get to the factory reset screen but even if I go through there I get the same black screen (though backlit). I can't boot into download. I'm downloading the .tot needed for stock, but I'm not sure if that'll be a lot of good without download mode. I have everything on my phone backed up from when I rooted it (I'm missing a few pictures but nothing major.) Any and all help would be appreciated. I've got a bunch of precalc homework and Prom in a couple days so I'm willing to sacrifice sleep tonight. Thanks! (Made this account just for this, though I've used the site a bit before.)

It's cuz you're not doing it correctly.
Yes, you're supposed to depress "vol down & power" but once you see LG logo, let go of both buttons and then immediately hold down only the "power" button.
After a few secs, a white factory reset screen will appear. Ignore the warning and press power button. I know, its kinda scary at first, but then phone will load into recovery.
I can get to the factory data reset screen but when i choose yes it just gives me the secure boot error. I am able to put my phone into download mode by pressing up volume and power when plugging to pc, but cant get pc to recognize it. I am sure I am missing something.
i am also bricked. i cant get into download mode or recovery. i have twrp installed, cant get to that either. i have tried every button combination and all i get is a black screen and vibrations, no lg logo. need help.

Call LG verizon will void your warranty
Has anyone made any progress or did all just send back to LG?
I am in similar shape, can get to the white factory reset screen - which does nothing once I accept.
I can also get into download mode, but the phone isn't recognized.
Wanted to confirm before I try to send it back that I can't fix myself.
Thanks!
Also, did anyone who was able to get back to the hard reset screen have luck sending to LG? Or did it have to be completely bricked?
Im also bricked. And there is no recovery mode. download mode is usable. but when i in twrp before brick i deleted efs because i have a back up after that recovery had corrupted and driver in the rom memory to talk to pc had also deleted with efs(i think). I have an idea to fix but im not sure
If I can change rom from mainboard and replace it other rom from other lg g2? Will it solve my and our problem??????
thanks to reply.
My G2 suddenly just stopped working yesterday. When I try to power it on the phone either freezes shortly after the boot screen, gets to the homescreen then shuts off, or boots to an all blue screen. I can access TWRP but haven't been able to fix it with anything I've found. My pc isn't recognizing the phone so don't know if I can flash another rom. Also tried factory reset with no luck. Any help please this is driving me crazy!!!
The same thing just happened to me! Someone please help us! IS there a solution to this?

Ok, since there is little to no information out there I thought I would share how I created and fixed this problem.
I received a new phone under warranty because of a failing sim card reader. Naturally, the first thing I did once I received it was root it. Next, I thought I would be slick and use flashify to flash a custom recovery (TWRP). Little did I know, with the new version of Android, our phones have a locked bootloader. I freaked out when I saw some weird error messages about it and tried to power off the device in the middle of it booting. BIG MISTAKE. In hindsight, I am assuming that it was re-flashing the factory recovery when I powered it off.
It gave me a solid blue screen for two hours, unless I held the power button for 10 seconds, which would just repeat the process from black screen to solid blue screen repeatedly. I tried to reboot into recovery for 2 hours by holding volume down and power. 2 HOURS!
At that point, I realized that I may have some luck getting it into download mode by powering it off, then powering it on with volume up and power and plugging in a USB cable. VOILA! It booted up normally (somehow) and I got it running the OS.
After that, I made sure that I did a factory reset by reverting to stock using the LG Software Upgrade tool.
The moral of this story is, if you are going to try to install a custom recovery on 4.4.2, make sure you know what you're doing. It turns out an app called AutoRec did the trick for me.
dsljk2009 - I hope this message helps you, or anyone else who may think they've bricked their phones.

I didn't get the blue screen but I kept getting the security error screen on my d802. To turn it off, I kept holding down the power button for about 10 seconds after the screen went blank. This caused the phone to remain powered off. After that, I was able to boot into download mode. Maybe this method will work for your phone.

Don't know of any other methods because holding down the power button got the phone to turn off and allow me to get into download mode. From download mode, I was able to restore a stock 5.01 ROM to my phone via LG Mobile Support Tools.
LG G2 Bluescreen then no boot after disconnecting battery
Found my LG G2 with a completely blue screen. It would not turn off. Took it apart and disconnected the battery. Reconnected the battery and there was only a blank black screen and the phone would not boot. Zilch. Even with pressing the power button with the volume down to boot into recovery.....still zilch.
I sucessfully got my phone to work again using a hair dryer trick on an LG G3, which I found here.
1. I took the back off the phone, disconnected the battery, and removed the SIM card.
2. I then used a hairdryer on high heat and blew the heat over the uncovered areas for 10 minutes.
3. I let the phone from hot to warm, reconnected the battery and put it all back together with the SIM card replaced.
4. I booted into recovery and restored a TWRP backup, and my LG G2 is working like a champ again.
Saturday evening I got a notification saying 5.0 lollipop was available for my s5 so I eagerly downloaded the update. During the update my phone froze and crashed (had this happen twice earlier in the day) and it rebooted to the update screen. Once the update finished installing the phone rebooted like normal and sat at the verizon screen for about 2 minutes before crashing again. This caused the phone to enter a boot loop that ended up making an open padlock symbol appear on the start screen. After this appeared it took me to a screen that said "System software not authorized by Verizon has been found on your phone". After getting this error I tried using Odin and Kies to reinstall 4.4 on my device. The install was successful but after the phone booted it was freeze and crash again leading to another boot loop and a "recovery booting" message in the top left screen. It now either boots back to the System software screen or loops until it hits the recovery menu. Is there any way to fix this or did Verizon brick my phone?

Ok, so I am safe now. I was able to flash a stock NK2 Kernal.
Pull the battery on the phone. Hold down Vol. Down, Home, and Power and go to download mode. Plug in the phone, and open Odin. Flash the kernal.
Reboot and you should be ok. This just worked for me.

This worked for me as well, thanks! For anyone that wants to know, I used "NK2_Stock_Restore.tar.md5" specifically. You can get it from this thread labeled as "NK2 Stock Restore".
I have a Nexus 7 2012 version since 2014, after many updates and installing apps it was becoming slowly and unusable, so I dicided to flash and install Cyanogenmod 12.1, after installing it, all was fast and smooth, I loved it, but after a month it was turning laggy again, so I decided to use Nexus Root Toolkit to come back to 4.4.4 stock. After flashing, the tablet still in recovery mode, I selected START using the buttons, and the Google logo appeared but a little message in the corner of the screen scared me, it said "booting failed" , so I tried to flash again, but now using the option "the tablet is bricked/bootloop" but it didn't work, so I tried to turn off the tablet and power in again, but nothing happened when I tried to turn on again, the tablet didn't turned on and now it still off, when I plug the charger the battery logo doesn't appear and tried to press the power button for 30 seconds without success, I need help guys, someone told me that it will be possible to fix it, but he doesn't know how to do it.
Thanks for your attention!
Hello,

Try holding power button and volume down until the Google logo shows up

About a year ago, I decided to try the 5.0 release. Upon installation and reboot, It stuck at the "Google" logo. I was able to get into the bootloader, and it said it was still unlocked, but I couldn't do anything: boot to system failed, and even boot to recovery failed. Formatting/deleting the various partitions failed (cache partition was corrupt but couldn't be formatted); flashing a bootloader from the latest Google images didn't help.
I fixed it by buying a used motherboard from eBay for $30. It was fine with 4.4.4/f2fs for about three months, but when I once again upgraded to 5.0, the *exact same* thing happened.
I now have yet another motherboard and will not ever upgrade past KitKat.
Had the S8 for about 3 to 4 months, rooted it four days after getting it; no issues whatsoever, it worked perfectly. Yesterday, after a day of not using the phone, I attempt to use it and find that everytime I try to boot it, it freezes after 10 seconds and reboots.
I have tried flashing stock rom of android oreo for the device and am currently trying to see if nougat will fix my issue.
Edit: After attempting to go into android recovery, I am told the device "fails to open recovery_cause", with an unknown error.
I'd really appreciate some help with this, as I've done almost everything I can think of to fix it.
Edit 2 (5/9/19): I've successfully flashed a version of android pie, which successfully boots into the initial setup screen. Same issue however, after around 10 seconds, no matter what I do, the s8 freezes and reboots.
Given up with the phone, tech support already recommended to go on here to post a question. A new phone has been ordered, and the S8 will be sold in non-working condition. If anyone has any idea about how to solve this still, please say something; if not, have a great day .
Thank you.
Hello,
I have the same problem.
I contacted Samsung with Samsung Members.
They said that i had an app who make the phone crashing during the boot !
They said the proof is your phone don't crash when you make an secure boot :
Turn the device off.
Press and hold the Power key past the model name screen.
When “SAMSUNG” appears on the screen, release the Power key.
Immediately after releasing the Power key, press and hold the Volume down key.
Continue to hold the Volume down key until the device finishes restarting.
Safe mode will display in the bottom left corner of the screen.
Release the Volume down key when you see Safe Mode.
Uninstall apps that are causing a problem.

With this secure boot, no problem during boot
The only problem, is that i have only "official" apps donwloaded with Play Store, and i never find the app that cause the reboot :s
