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.

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.

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.
i recently tried to edit my build.prop file on my LG G2 (LS980). i changed
Code:
ro.build.product=G2
to
Code:
ro.build.product=g2
(using root explorer, and mounted r/w) because i read that they should be lower case, and since my phone wouldn't update i decided to see if it would work. rebooted and got the error. the error is so bad that i cant even use my phone. the front touch buttons are missing and i cant tap anything except for the power off/reeboot/enter airplane mode. Also, 9 times out of 10 when i power off, the sprint spark logo appears then screen goes black, then reappears and turns the phone back on. furthermore, when i plug it in to my pc i cannot change it from MTP mode, and im not sure if i still have usb debugging checked. the lg mobile support tool wont recognize that a device is connected even with the latest drivers. ALSO, i cannot enter stock recovery! last night when i first got the error i entered it once, but i decided to look for other options as to how to fix the error rather than wiping. but now I WISH i wiped my phone then, because no matter what i do now, the phone wont go into recovery mode. i don't have TWRP or CWM, and i am rooted. I'm a noob and i don't know what to do at this point, can anyone help me?
i have tred looking for some sort of software that can let me access the phones settings directly through usb, but no luck. i dont even know if such a thing exists.
can you battle your way to settings/apps? hit options, reset defaults
otherwise you may have to boot into download mode and flash complete tot/kdz

Same happened to meee!!!
What can i do??
Hi,
Have a weird situation, but try as much as I may, I'm unable to resolve it.
My phone is rooted (international D802) and was running fine. Had a screen issue and got it replaced at the service center but their system identified my phone as a rooted device, and a couple of days later the problems started.
The issues I'm facing right now:
1. The phone doesn't charge when switched on, at all.
2. The phone doesn't reboot either.. not instantly anyways. If powered off, or rebooted, the phone doesn't turn back on, it just goes dead. It does boot again though if tried after a couple of hrs.
3. The phone charges when its off (shows no light or indicator though, like its bricked)
4. Cannot go into either recovery or download mode. Coz the phone doesn't boot when restarted or when i try to reboot into recovery.
5. When it does magically start after a few hrs (upon long pressing the power button), even if I try to go into download or recovery via the vol keys, it just boots to android.
6. The phone is recognized properly as LG G2 under windows and all the drivers install too.
7. The phone isn't recognized under Linux... tried both Ubuntu and Knoppix.
Travelling out of the country in a few days, really need to sort this out.
Any and all help/suggestions will be greatly appreciated.
Thanks in advance
Somebody... Anybody? :'(
When your phone rebooted I would recommend you firstly to activate USB Debugging in the developer settings. You said your device is rooted? So try to install the Auto Rec recovery here
https://www.androidfilehost.com/?w=files&flid=13763 - but make sure you are on Kitkat. Now, install the app normal and let the app install all things. After installation, the app asks you to reboot to recovery, now press reboot to recovery.
Maybe you have luck and the phone reboots to TWRP. In TWRP you can go to Reboot and then Reboot to Download mode.
Now (if all worked) you can flash the stock rom .kdz file of the d802 via the FlashTool 2014.
Hope you have luck, please keep me up to date if everything worked.
Yours, Flo
Good luck!!
Thanks a lot for the response Flo, but the problem is that i never got around to updating to a Kitkat rom... the rom i was never got updated and I was kinda happy with how things were working so didn't jump on to any other rom.
Anything I can do in my current situation?
Go back to stock via lg flash tool

here my issue.. so I'm using cm12.1 on my Canadian gaxaly note 3, and Im trying to reset my phone, which I thought would be just fine if I went to settings, then hit reset data function. in which it rebooted my phone, and tried to take me into recovery for whatever reason (likely to reset the phone..?) and its almost stuck there. it flashes like it tries to boot recovery and shows the team win logo for 2 seconds then shuts off and then displays the team win logo for 2 seconds and etc. etc, I tried to get it to download mode with no cigar, whatever button combination I do it always ends up booting recovery. cant turn it back on or anything. I plug it into my computer and it seems to not recognize it. I'm with virgin mobile right now and it's an almost 2 year old phone (got it the day after black Friday), so I'm guessing I'm out of luck for the manufacturer and the virgin mobile's help. Anyway I can fix the issue? any help would be appreciated.
Do you have access to a USB jig for force the phone into download mode?
What happens when you try to boot into download mode? Are you holding down the volume down, power and home button long enough?

Flash "CWM/Philz" recovery for your phone model and go-to recovery mode by some step:
1. Pull out batery.
2. Push in again.
3. Press "volume up + home + power" and wait ~5second.
4. You in recovery mode
I recommend flashing 2.8.7.1 TWRP if you can get into download mode in order to flash another ROM. CWM is outdated and no longer being updated.
If you want to flash back to stock, grab the latest stock ROM from sammobile.com.
my problem is kind of abnormal. i couldnt find solution anywhere so i came here. my device was zenfone 5(t00f)/lollipop.
so i wanted to root my phone. i followed this guide >>
HTML:
http://forum.xda-developers.com/zenfone-5/general/zenfonetoolkit3-24-40-87-t3406557
the tool i used is called ZenfoneToolkit_20160719, downloaded from here
HTML:
https://drive.google.com/drive/folders/0B0AFmAAcGS5xbWpTQzBQVTN3b1k
. its a bundle of .exe, .dll, .img, .bin files. but no need to work on them seperately, there is a simple cli tool from which you can choose what you want to do and it executes that file for you. below is the list what you can do.
1. Wipe Cache
2. Factory Reset
3. Flash Boot
4. Flash Recovery
5. Flash Fastboot
6. Flash Stock ROM
7. Root
8. Unroot
9. Unlock Bootloader
10. Relock Bootloader
11. Zenfone Rescue aka Debrick
12. Fixing Generic IMEI 004999010640000
13. Backup MicroSD
14. Flash Boretz Kernel Lollipop
so wiped cache[1] first then i tried to root[7]. sadly it didnt work, when i turned the phone on it took me to fastboot screen, there i had only a few options like, normal boot(doesnt happen), recovery mode, restart. when i turned it off and pressed power and volume up together it would go to recovery where none of the options works. i though that was what called brick, so followed this guide to make my life better

.
my phone by default came with kitkat. so when i downloaded the firmware i wanted to get a kitkat. but i couldnt find a matching recovery img and firmware for kitkat on asus official page. so i downloaded jellybean. ASUS ZenFone 5(T00F/T00J) software Image: V1.18.40.9 ww for firmware from here
HTML:
https://www.asus.com/support/Download/39/1/0/2/96nqlxHp1VKV4Rdz/32/
. and recovery img is 1.18.40.9_ww_recovery.img from here
HTML:
https://www.asuswebstorage.com/navigate/s/644D9E0A19714899974C75FC4B6C87EDY
. i dont know what "ww" means in those name but i saw it in my software version before so i went with it.
All the steps went smoothly, by the end of it i guessed my phone charge would be low so i put it in charge and turned it on. first time it turn on without a problem. i checked out a few things and leave it for charge. after a while i came back and battery was 0%. i thought i would be wise to plug out and in charging port again. as soon as i pull out the pin, screen instantly turned black and the phone went dead after a looooong ass vibration.
now when i try to charge the orenge light at top lights up but the animation that shows battery always show its empty. if i try to turn it on while plugged, it shows asus logo/intel logo and goes dead again. if i try to turn it on without being plugged, it shows a battery logo with a question mark, which i think means the phone cannot find battery.
i am stuck here.... plz someone be my savior.
Hello my dear, to get out of this problem I did the following: I connected the phone to compuador by USB cable (with himself off), then he calls and gets the question symbol, it held the power button plus volume up he must restart to get the logo asus about 4 seconds after loose the power button and continue with the volume button up insured. It should enter into fastboot mode there do the necessary procedures to reflash the system.
I hope you helped, hug!
