Hold the power button until you get a black screen. Download LG Mobile Support tool and the LG Drivers. Plug USB In and then hold the Power + Volume Up key. On your screen, click Upgrade Recovery. From there, you can do a factory reset through download mode of your phone.

In case you did the latest firmware ota upd,there is a topic that can solve you problem as long as you can access TWRP(even if you didnt do the ota it will,i tried that myself) Here is what you need to do.
use TWRP's "terminal command" option to run the following:
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
You'll have to type that whole thing out, and be VERY careful with spaces and punctuation. One wrong letter and you could nuke your phone.
This will probably fix you problem when it has to do with any update.

Thanks for the responses. I finally fixed it.. I started the procedure from scratch with a new laptop and somehow it worked lol

It happened to me and now phone hanged in download mode and can not connect to pc. Did you have a solution?

Solve
Guys! I had the exact same problem today. My solution was to keep pressing the "try again" button every time the error appeared on my computer screen. It took some time but the error was appearing at different levels each time in this order : 45% 57% 65% 80% and next the instalation was completed. If it doesn't work try switching to another computer if you can. After the firmware update hits 100% your phone will restart and the LG logo will appear(the led changes its color during this process). At this point you have to just wait a while. Then a dialog box will appear saying that the applications on your phone are configuring themselves. After that your phone will start and work normaly. The cause of the error is the lack of memory on your phone. If those idiots working for LG would say "YOU DON'T HAVE ENOUGH STORING SPACE" this stuff would not happen.
The phone is not rooted!(IMPORTANT)
Phone name: LG G2
Phone model: D802
Old software: 4.4.2 (KitKat)
Actual software: 5.0.2 (Lollipop)
I hope this hellped you solving the problem.

My lg optimus exceed 2 will only display on screen firmware update which is froze the phone won't do anything Please Help! !!!!

Turn of the phone and enter to download mode again and try flash to stock kdz file with lg flash tool

I had same problem "firmware update", simple just remove the battery and sim for 15 sec. then put it back and restart.

Hello
I can't access my LG g2 after trying to wipe the system and it runs on frozen screen. Kindly help out please

My LG x power died and I went to plug it in and a screen popped up saying,"Firmwire Update 0%", so I kept it plugged in for the next half an hour, and it still said 0%. I've tried resetting it and powering it off but nothing seems to be working. What do I do?

Download lg flash tool.
Download lg g2 stock firmware.
Press volume up button and insert usb cable. You will see download mode.
Open lg flash tool and flash the kdz( original firmware) through flash tool.select cse flash.

My LG V20 got stuck on the Firmware Update screen. It appears every time I restart the phone and I have to take the battery out. If I start the phone plugged in it starts normally. I was able to do a factory reset, the phone started normally a few times without being plugged in, now it's back to the Firmware screen. I can use the phone but need to restart when it's plugged in. I hope Oreo Update will fix it. I don't know much about updates, but do big updates like that reinstall the drivers as well?

Hello everyone I also have this kind of experience so many times in my g2 mini.stuck on Firmware update. What I’m doing is,
1. remove the battery to turn it off. Plug your charger and before plugging it to your phone hold the volume down and plug in until tou see the android is updating; or
2. Just simply hold the powerbutton + volume down until you see Android is updating.
I would love to see your feedback if it helps.

The only way I could get it to work was the following; however there is one thing to try before you try my way because mine did this also - after the wipe and flash with flashtool etc. The only way I found to get out the bootloop was to do a factory restore after when its looping. So from the boot screen loop hold the power button until it goes off then on then off again.
Then do the process to get into the recovery so hold down and power then release power as soon as the lg logo appears (first one) then press it again immediately that SHOULD get ya to the grey factory reset screen. Press the power button 3 x and it should do a factory restore and boot up this time. First boot may take a minute it should eventually start up.
Failing that try this - Open the lg mobile support tool and connect the phone in download mode (volume up and power with plugged in usb on mine) then go to options and upgrade recovery. it will download a file usually about 2GB then install it, the phone will reboot at 100% on the phone and 80ish% on the lg tool it will then start into the setup feature,
DO NOT disconnect the phone until it gets to 100% and finishes. This way you shouldn't need to do an extra factory reset.
I understand for this the phone needs to be seen on com 4 (it shows on the phone screen) so if necessary go into device manager with the phone still plugged in in download mode and select com ports then select the phone com port then right click >properties> advanced and change the com port to 4. It may tell u its already being used but don't worry it is fine. Save and exit device manager.
please bare in mind these are just my experiences on MY LG D802 however its worked every single time for me without fail and ive done it a good few lol.

[Q] [Q} Is my D802 Bricked?

Hi all

So I can't flash kdz image.
2.I am able to access TWRP with official factory default( power+volume down to power on, when LG logo shows up, release power and volume down, then hold power.). But no matter I flash CloudyFlex which in my sdcard, or sideload flash others ROM, the cell phone will no boot up, always stuck at LG logo.
Any possible way to fix? Thank you very much.

not sure, I did few stupid things before.
1. I flashed LG G Pro 2 ROM here: http://forum.xda-developers.com/showthread.php?t=2673143 but it not good for me, so i went to recovery. but this rom replaced my recovery to a unknow one, not TWRP. when I was in this unknow recovery, my phone linked with PC via USB. PC found a lot of unformatted drivers, I did the most stupid thing: formatted one of them.
2. G Pro2 rom still can boot up, I flashed stock kdz, and rooted it with ioroot10, then flashed TWRP 2.6.3.3.
3. copy CloudyFlex_1.4.zip into sdcard through MTP mode of stock rom. reboot into recovery TWRP, flash cloudyflex, phone never boot up again.
4. No matter what rom i flash, always stuck at LG logo and the phone become hot.
sorry for my pool English.

Sorry man, I have no idea what you may have formatted then.. :/
I can't think of anything right now.. If you can't get to download mode and flash stock kdz again.. Then I don't know. I hope some one comes along that knows something. Sounds serious. I'll keep on thinking about things. But I have to leave the house now so..
Sorry.

can not reboot into a custom recovery

I can not use my touchscreen!
For days, i am trying to solve this problem, but still can not, i am really upset about that, i need your help.
Firstly, my device was D802 international and os was 4.2.2
I rooted, installed a recovery, then installed a KitKat with Twrp.
After i wanted to turn on, i realised that the touch screen was not working properly. Actually it is so bad, that you can even not enter the menu of the phone with the touchscreen.
Then i connected a mouse to phone and went to settings. Yes, it was 4.4.2.
I had to install a new rom to solve the touchscreen problem, but i couldn't, what ever i did.
With the offline procedure of Lg flash tool (in download mode), the installation stopped every time in 15% depends on a problem of usb connection.
With the online method, it said that the batery is not enough to contunie. (But it was 100%)
Than wanted to install with Twrp or cwm. I rooted, flash the recovery but can not reboot into the recovery menu of twrp or cwm. When i press reboot into recovery, it directs me to the stock recovery of the phone. (In which there is a lying android with a red triangle above it's body)
I also tried adb(from the custom recovery menu) , pc was recognizing phone but the phone was not reacting to the commands i entered from pc.
I've searced a lot in google but couldn't find a solution.
Please help. What's the problem. What can i do?

You could try this. It worked for me, although, i had a different issue. My phone was not rebooting into recovery due to the "Secure Bootloader Error". Nevertheless, it installed cwm on my phone and i could boot into it. So, you can try it. It may or may not work

SM-G950F won't boot, hard bricked?

I had to reboot my device due to problems with my speaker. Now i'm not able to boot anymore.
I'm only able to get into ODIN Mode, and flashing new FW or TWRP does nothing. It'll flash correctly, but as soon as it sends the reboot command the device powers off and does not boot, and no, it does not reach the "Galaxy s8, powered by android screen".
It does not want to power on, and only responds to the odin button combo, can't boot into recovery either since nothing works.
I was running the latest version of Renovate Ice if that matters.
I've searched trough some other threads, but it seems like i'm the only one that's having this problem.
Any help or thoughts would be greatly appreciated!
Edit 1: I've tried flashing both AQK7 and AQG5. Both flash fine, but as soon as odin sends the reboot command to my phone, it turns off and does not turn on.
Auto Reboot is ticked. Same goes for any version of TWRP, it will flash, but when it has to reboot the device turns off and does not turn on. There's nothing on the screen, its completely black and the only thing that does work is Download Mode. I've also tried ereasing nand, and repartitioning storage. Both seem to have 0 effect. As stated in one of my replies, i was running the latest build of renovate-ice with magisk, no other mods, or themes installed.

Im a bit confused - you can only boot into download mode (not into twrp?) and the phone is in bootloop? Have you flashed anything (mod?) before or activated a substratum theme which could cause this?
The only thing I can think of is a) you delete in twrp file manager the corrupted file, if there is something like this or b) a twrp restore from a backup. Boot into download mode and then do not press vol up to go into odin mode but press vol down to reboot - then immediately press the combo for twrp and you will get to the recovery. This helped my s8 many times when I was in a bootloop and couldnt boot up twrp

Thanks for the reply! Other than using the Renovate-Ice rom, and running magisk the thing was pretty much stock. wasn't messing around in twrp either. Its not stuck in a bootloop either, it just refuses to do anything other than go in and out of DL mode. The phone does not respond to any button imputs other than DL mode. As stated in the OP it does not boot at all, just a black screen. i've already tried to reflash a stock FW and TWRP, but that does not seem to work...

try the method I did - this is the last thing I could think of, before reflash the whole phone with odin

but you havent installed Viper4Arise or anything like that?
Because of this my speaker also stopped working a few weeks ago

if you can get into download mode then get into download mode and leave phone, then download samsung smart switch for your pc (older version like 4.1.17022_20 from here http://www.filehorse.com/download-samsung-smart-switch/29268/ that allows phone based recovery), once installed open it, then click on more at top right, (do not update the software if you get a prompt) select emergency device recovery...., then click on right tab (device initialisation) and fill in your phone details etc., connect your phone (in download mode) and follow the process, maybe it works, you'll need to root and install TWRP again but thats no big issue.
