My wifes LG G3 got the lollipop update (I presume) but it got stock at 22% at the firmware update screen. After 2 hours my wife apparently got tired of it and took the battery out. The phone now repeats the procedure on boot and instead gets stuck at 23%.
What can be done here? Stock unrooted.
ps: googled for a good 15 minutes before posting but found little information on what to do.
Can you enter in download mode?
Turn off the phone and press Volume Up + power and hold
I get "Hardware key control mode" menu cancel mode on mode off. Seems unrelated to download mode?
Not related.
I believe your only hope is repair shop.
You have waranty?
Yeah she still has warrenty and it hasn't ever been rooted so should be fine. The problem was more of the nature wife needing phone NOW
I GOT DOWNLOAD MODE. Did the UP+connect usb cable instead, how do I use this to unbrick the little sucker?
Flash KDZ manually.
You can find files and tutorial here: http://forum.xda-developers.com/showthread.php?t=2785089
In fact download mode only worked once, then it stopped working stopping at the lg logo screen. Guess it's just to go to the repairshop tomorrow
I too am facing the same problem. I connected the phone to my PC on which I have the LG PC Suite installed.
The suite prompted for a firmware update for which I clicked. The download took forever and then the update started but during the process the phone had to restart after the first part and the phone keeps repeating its logo with music.
The suite is downloading another update (possibly the second part), but this will also take forever and I don't know whether the phone battery will hold up with its perpetual logo start-up.
This is real crappy my wife's phone just ended up at the shop. 4 weeks to get it back. Thanks LG.

I flashed the stock firmware onto my phone, and all was going well until it turned itself off. It then rebooted into Download Mode, and got itself stuck on 'Firmware Update'. I pulled the battery, rebooted and it went from the LG logo straight to the Firmware Update screen. I've tried going into recovery (which works, but pressing yes OR no still takes it to Firmware update. Going into download mode doesn't work either.
I tried to re-flash it using the LGFlashTool, but my PC can't find the phone in this state. I bought it off a guy on eBay 4 months ago, and it worked fine until the first sentence of this post happened.
EDIT: it's the international D855. The Firmware Update screen says '910K B0 QEM'

Thats not actually right
Booting into recovery normally should factory reset the phone. Would you be able to post a picture of the firmware update screen

I tried it then. When I do it, I get the normal 'No (Exit)' and 'Yes' and then the same thing to confirm it. It then goes to the LG logo, and boom! Firmware Update!
I don't have a camera (stupid, I know) but, if you boot into download mode, it looks just like the screen there. Except it shows '910K B(0-99) QEM' in the update box thingo.
Hi, i have the exactly same problem, even if i try to power up the device normally or in download more it goes directly in to firmware update. Any way to fix it or install LGE MTP Driver so my PC will see my phone in order to flash it again?
LE: Video
I have run into the same problem like you guys. I recently updated my phone and it started to malfunction with resets, crashing and eventually got it stuck in boot loop. Then it booted into a green screen that said "demigod crash handler/tz crash" thrice. Instead of a hard reset I decided to using the lg mobile support tool to fix it. During the upgrade recovery my phone went into download mode/firmware update. I could see the progress bar moving and then get stuck and my mobile would switch off. Took out the battery, disconnected and reconnected the phone and tried the process all over again but in vain. I repeated this at least 8 times and eventually gave up. Now my phone is basically useless and only boots into firmware update. Hard reset doesn't work either. Can somebody please help me fix this?
I HAVE THE SAME PROBLEM :crying:
910k b0 qem
I tried to flash TOT file and it kept failing around 10%. I read somewhere that I should select the "Flash Board" option so I did. This also failed and left my phone booting to "Firmware Update" screen with following text in the gray box at the bottom.
910K B0 QEM
Windows no longer recognizes the devices and fails to install drivers.
I believe that what is required here is the "910K resistor flash cable"
Something like this ebay[dot]com/itm/OCTOPUS-Z3X-MICRO-USB-LG-P970-P990-P999-CABLE-56K-130K-910K-VARIABLE-RESISTOR-/131321398015
Can someone confirm or offer a solution?
P.S. This 10 post URL limit has got to go!

It is possible you flashed the wrong KDZ or TOT file
You can also try to hold the power button and wait untill the LG logo appears
anyone have any luck? Im stuck in this mode also
Hey! Check the bottom for TLDR.
I have had my G3 since they came out (have the 2GB, 16GB RAM version), and even got the G4, but remained with the G3 since it didn't have any issues with rooting and recoveries...
Anyways, I was talking to my brother on WhatsApp yesterday and ended up checking out my Hangouts messages at the same time. I believe I accidentally hit the camera feature on Hangouts, and then everything froze. I could still talk to my brother, but I could not get to the home screen or even change from looking at Hangouts. I turned off the screen in hopes that I could get back in, but when I turned the screen back on, I could not log into the phone (I do not have a pin or password, it has no lock at all).
After a few more minutes talking to my brother, it suddenly shut off. When I tried to turn it on it went into a bootloop where the front light changes different colors, and the LG logo continues to show that shine going around the logo.
I was able to get into download mode and went ahead and tried to flash a KDZ as per instructions (I have done this in the past). The install would complete and the phone would give the prompt about updating all the apps. Once that was done, it would show the LG logo and again for about ten minutes. Afterwards, it would get stuck in updating all the apps again and performing the same process...
I also tried using the LG PC Suite and trying to "Restore upgrade errors", but every time I would click that option, I would get a Windows error that something happened and close out the program (it never recognized the phone). I then used the LG Mobile Support Tool, which allowed me to perform an update for the firmware. It too completed, but then went back into the process of updating apps, showing the LG logo, then looping.
The final thing I tried was doing a Factory Reset. I was able to get to the area, and when selecting yes, it immediately went to the LG logo and "Life's Good" sign, which it would never get passed. This is also what happens when I try to turn on the phone and wait.
I contacted LG, which was pointless, as I expected. They wanted me to go to a local repair shop, which is of no use to me if they can only perform the same things I have done.
TLDR: My phone can get into download mode and the Factory Reset area, but flashing stock firmware, or performing the Factory Reset, still leads me into one of two bootloop situations. LG PC Suite and LG Mobile Support Tool seem to be of no use.
Does anyone have any suggestions? Is there anything I can try that I haven't?
Thanks in advance!

Hello
I am new to working on these phones so I apologize in advance if I don't properly state any processes or terms correctly.
I have a stock non modded Verizon LGG3 VS985 that experienced problems with WiFi and Bluetooth not working and significant battery drain. This happened right after a recent update to marshmallow. I tried cache clearing, safe mode, hard reset and nothing solved the problem. I decided I wanted to take the phone back to factory condition. I started with the LG flash tool that uses the .tot and a .dll. I ran the flash and when the program got to approx. 80%(at checking mini os phase of the flash) the phone began to reboot and only got as far as the LG logo and after about 2 min of the phone trying to reboot the flash program said fail, usb connect or something like that. At this point the phone will only start and go into a loop that includes the vibrate and the LG logo. and that will cycle until I believe the battery would die if allowed. I then found a link here at XDA (https://forum.xda-developers.com/verizon-lg-g3/general/guide-flash-to-stock-10b-kdz-method-t2928140) that uses the KDZ method, was well written and easy to follow. I ran it on the phone and it was going great. The flash program got to 88% and the phone went into the boot loop with the vib and LG logo . The flash program continued to run until it was complete while the phone was in the boot loop and it got to 100% and said that the software installed. I powered down the phone via battery removal and now when it tries to boot it vibes, shows the lg log and then the green android symbol shows for about 2 seconds and then it does it all over again. I have tried a hard reset and nothing changes. I appreciate any ideas any of you may have on what I can try to get this resolved. Thank you.

Not sure I understand the question completely, but I did place the phone in download mode as per the method you mention prior to both attempting the KDZ method and the TOT method of going back to stock.
Hi Forum.
This is my first post and I need your help!
I've looked everywhere but cannot find solution although several people reported similar problems.
My LG G3 D855 suddenly crashed and got stuck in the loop constantly booting or showing black screen.
At some point phone showed me green screen, apparently Kernel crash
My phone took OS update a week ago which potentially may be related.
I also heard it might be due to poor battery. I purchased new one and the same result.
Phone does not indicate charging when connected to power.
When I try to put in in Download mode (Volume up and connecting to laptop) it displays icon of Download mode but then it goes black.
It managed to display screen Firmware Update, but now I cannot even show that.
I've installed LG PC Suite and LG Mobile Support Tool
None of them detects the phone.
I tried to do factory reset (Volume down + Power button). After confirmation phone reboots and situation is still the same.
What would be next step to diagnose and fix the problem?
Thanks a lot
Hi,
Sorry for you.
But it seems that your motherboard is dead.

I hoped it would be something else since it is going int Download Mode.
I suppose you are right though.
I did not manage to go any further with this.

THANK YOUA to ANYONE that can help point me in righht direction. Also i forgot to mention non rooted completely stock.
So you've already held power and volume down at the same time with the phone on?
I am too having the same problem. Mine is a T-Mobile LG G8, stock non rooted, got updated last week and then acted funny(some apps crashed), I restarted it won't reststart; Stucked on some LG-G8 screen. I hard reset it (Vol Down-Power/LG Screen, release and then hold power button; and then hard reset), After that: it stuck on boot loop.
What I can try next?

When my update came through on T-Mobile it got stuck at the Tmo splash screen. Pressed the power and volume down until it turned black and let go. It rebooted normally after.

Hi guys, am just a newbie here from Malaysia and a new owner of a 2nd hand LG G8 ThinQ (LM-G820UM); no idea where it's from but got it already with Android 10 update.
'twas working perfectly fine for a few days, but suddenyl got stuck in bootloop after I reboot (Power + Volume Down buttons) the phone when I was trying to change to a different SIM card. It would remain in bootloop until the battery is drained.
I can connect it to my laptop and seems to be detected pretty good and able to switch to Download Mode, but can't re-flash with either Flash Tool or LGUP.
- Have tried to use different Flash Tool versions - in version 2014, the flashing will just stop at server error, in 2016 and 2025 versions it will require LGST login (apparently to connect to some server which require registration).
- same goes true for LGUP, both versions 1.14 and 1.16 (patched version) will just stop at 4% then the apps will close without any error or anything happening in the phone.
Appreciate any help to recover this phone which I paid for a few hundred dollars as I was impressed with the spec and was so delighted to a very good spec phone; then this happened.
Thanks!

I'm in the same boat but with ATT. LM-G820UM I believe. Completely stock software. I just had it sitting on the charging dock for a while and I came back to it and it was stuck in a bootloop. No idea what's caused it, but I can't seem to get it to stop for anything. This is one of the many reasons I find not having a removable battery deeply upsetting :/
okay will try that as soon as i can get this thing to boot normal again it now stuck on the lg g8s screen think i flashed the wrong abl_a and abl_b files
Has there been any progress in getting this fixed?
Other than flashing the entire stock kdz not sure what else can be done...
