Still stuck in LG logo bootloop after using LGUP - G3 Q&A, Help & Troubleshooting

Hi, I have an LG G3 VS985 on 47a (according to LGUP) and I recently tried installing an OTA update that I have been putting off for a while. During the update I got an error that froze the updating process so I pulled the battery. After pulling the battery I can not get passed the LG logo in the beginning. The logo will show up, turn black for a few seconds, vibrate, then restart again. I tried downgrading using the TOT and KDZ methods but kept getting a no ks version error or some other type of problem. So then I decided to use the newest 48a KDZ file and LGUP to update/overwrite what I have installed right now. The process starts and the phone shows that the installation is working but when LGUP gets to the point where it has to restart the phone (about 80%), it just keeps bootlooping instead of going on with the installation. I tried clearing cache, factory resetting, and everything else I can think of. I read that the bootloader might be corrupted? If that is the case, how would I go about fixing it? Thanks in advance.
Edit: Another strange thing happens when I plug my phone into a charger from the off state. Instead of showing how much battery is charged, it just shows a loading circle on the battery picture then proceeds to restart into the loop (without me touching the power).

Exact same problem I'm having
1 difference my led light does not work . Is there a fix? Need help

[Q] Please Help, Hard Bricked lg optimus g pro e988

The phone is showing black screen after i flashed exitrecovery.zip file since i got stuck into a recovery bootloop and right after when i pressed reboot button in twrp phone died. Have i got the phone hard bricked?? :crying:
What i have tried so far is pressing various keys combination and nothing is happening, tried to get into download mode but right after putting the usb cable connected with pc into phone it gives a notification sound but doesn't shows anything on phone screen :crying:
I also tried to flash the stock rom with lg flash tool 2014 with kdz file but it reaches to a point in the beginning and it gives an error message that the "phone isnt connected pull out the cable and retry" and after pressing retry few times it gets stuck at 60%
Please help, is there a way to get out of this :crying:
When something similar happened to my Galaxy S4, I charged it to 100% first. Then I tried flashing the stock image back to it twice. The first time did not seem as if it completed. Second time was the charm. I know the phones are different but the symptoms are identical.

LG G4 H811, crashed and bricked?

Hello to all of you who's reading, I ask for help from all of the skillful and knowledgeable folk in this wonderful community, I have a LG G4 phone that ran on CM.13, everything was running fine up until two days ago, phone just froze for a minute, nothing was responding, it crashed and LG logo came on, attempting to power on, but 10-15 seconds later it goes blank and lights up LG logo again... Now I've tried getting into TWRP but factory data reset msg comes up, after hitting yes and yes screen lingers frozen for another half a minute until LG logo shows up. I can get into download mode and tried flashing a stock image with LG Flash Tool 2014, it looked like it went through successfully but ends up doing the same thing... loops without ceasing. Do any of you have any idea what is going on and how can I get it fixed? Thanks for reading!!

LG G3 D855 Stuck in Weird Bootloop...

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!

Verizon LGG3 VS985 not booting

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.

Sudden death of G3

Hello i have Lg G3 D858HK went unresponsive after using facebook apps while listening to the music.
It completely unresponsive and i pull out the battery and turn it on.
Only blank screen with blue and red led sign. Is my motherboard problem?
I tried to boot into twrp and reflash the rom i used which is Fulmic 8.0 and
same problem blank screen.
I start digging into countless of thread like LG G3 Hard Brick Recovery
I managed to flash partition using extracted .tot from LGD858HKATv10d, still it won't boot.
I continue with LG flash tool 2014 on download mode with trial and error with the problem always stuck at 4% S/W upgrade
and keep continue to ask me to disconnect and reconnect the phone. Somehow i managed to flash firmware
using new firmware D858HK30b_00_0906.kdz.
I thought the problem is gone, now it stuck on bootloop and sometime with dead android guy with warning marks on his body.
I do factory reset still not working.
Is it i flash the wrong kdz file?
I have clueless right now as where to seek help. I don't know what is the actual problem
motherboard or software.
