Stuck In Boot Loop After LG Bridge & Uppercut - LG G6 Questions and Answers

So long story short I tried to return to stock from fulmics.
There are no good guides to even follow so I'm trying to piece together info from lots of different locations.
It seemed as easy as booting into download mode and using LG Bridge to revert everything to stock. I tried that and got stuck in a boot loop.
I then tried the same thing with uppercut and I'm stuck in the same boot loop.
I'm really not sure what I'm supposed to be doing now. Does anyone have any advice?

Have you already tried to do an hard reset? Since refurbish flash on lgup doesn't work in this case a reset is usually needed in order to correctly boot the system

I think I've only managed to do a soft reset (power + vol down). Trouble is I'm now stuck in the loop of:
- Bootloader unlocked screen
- LG splash screen
- Boot up noise
- LG screen with animation (like it's loading)
Then it just repeats itself. I'm not sure what else I can do other than run the battery flat as I cannot even turn it off.
EDIT: I think I'm just an idiot. I was using the wrong button combos. Feel free to delete this thread it booted up as I was typing this. *facepalm*

Thanks for the replies anyway, it's been a long day haha :highfive:

how do you fix this issue?
i face this problem too as my lg g6 stuck in boot screen and i even cannot turn it off
using combo power + vol down button cannot help. it just keep restart and stuck on boot screen
Edit: Nevermind, i find the solution by connecting g6 to pc paralel with vol up button press when restarting the phone (before lg logo appear)

LG G2 Bricked Tried as many things on xda as I could find.

Hi Folks,
I had TWRP installed and updated cm11 with a new nightly. I did a wipe cache and restarted. Phone got stuck on the LG screen. I could not get into recovery after this. I then used the LG support tool and flashed using 'Upgrade Recovery' option.
Phone now is stuck on same LG boot screen but now LED flashes also.
Can anyone help? I am really stuck here guys. :crying:
Cheers,
Trev

Doesn't the hard reset combination get you into recovery?

Did you select 3GQCT instead of CDMA which is selected by default ?
See if you can get into recovery once again.
Some tips: Hold power and down to make device restart, then let go... As soon you see the lg logo hold down and power. Timing is the key. There are sometimes I think I don't have recovery but in reality i do. Its all user error. If that don't work, try get in download mode. And flash zvc tot and get back to the stock.

Do a hard reset. it helped me yesterday. It's just that the hard reset key sequence for KK roms is different than how it was with JB. try to google it because I lost the topic.

Hey,
I'm in the same case but the R&D soft say there is an error. Plus I can't acces the hard reset menu nor recovery...
I can't also see my device on recovery as I only see in the device manager : LGE Android Net USB Serial Port.
And this is like that when I try to boot or when I'm in download mode.. Any help would be great...
PS : I try to make a restore with the LG Mobile Support Tool (the true one) but will only get answer in 6hours (best connection ever!!)...
Edit1 : That worked! I get out of the download mode and let the software do is job and there is new! Now I have to put a pin /password but I don't know which one ^^' ... I've tried to go back in download mode or hard reset mode but it don't work..
Edit2 : I don't get how but I manage to get in download mode. After that I perform a restore to another kdz and now I'm using the factory reset which seems to take a lot of time..
Thanks for the replies folks. Got it sorted out. This seemed to be the only way to get it sorted :

[Q] Hard bricked G2 after flash

Hi everyone
I may have bricked my G2. I use to have a Samsung Galaxy S which I flashed many times so I kinda know when I mess up with instructions. This time though, things look a bit more serious... Anyway, here is what happened:
I flashed the Cloudy G3 rom (1.0) for my G2 D802 32gb. Original rom was stock rooted 4.4.
I followed the instructions :
- Backup rom
- All wipes
- Flash kitkat baseband
- Flash rom zip
- Get through the aroma installer steps
But then, when it asked to reboot, the phone just shut down.
Now it won't turn on. All I have is a quick look at the LG boot logo, and then the screen goes all black (blacklit is still on) again.
All I managed to do so far is maintaining the LG boot logo a bit longer on screen by alternatively pressing volume + or - at random times.
I can't access recovery or download mode anymore.
Plugging the phone will only show the LG boot logo and do all the same.
The phone is no longer recognized by my computer.
When I plug it, I get 13 new windows asking me to format the device and one I can explore.
Inside, there is one folder named "Image", filled with 51,4 Mb of files...
Quite confusing.
I don't know what to do, so any help to get the phone back to work will be appreciated
Thank you in advance.

At least I'm not alone :laugh:
I found this thread but haven't tried yet. Don't know if the problem is similar.
I really hope the phone isn't dead, it's almost brand new
This is exactly what I have . The main problem is we can not see phone partitions. Always the alarm "can not access " or "format" !Waiting for some body to help restaure our LG G2.

Are you still under warranty. If you can't get into download mode that means that LG won't be able to either. You could process a return directly from LG.
Problem solved ...
Somehow I did manage to hard reset (vol - & power, wait for LG logo, release and then press vol - & power again) and then access recovery mode, so I did restore my backup (which had been renamed to ... 1970-05-01 ! lol) and my G2 is now back to life.
Weirdest thing ever... Kinda worried about flashing it again now !
Thing to remember : always have a backup file.
You are lucky man! I've done it but nothing after. I can access to hard reset but when I push power button the screen goes black as before ....
Is it actually in "Download Mode"?

So, if my G2 shows "Download Mode" on the screen with the little white dots, but it's not recognized by Windows 7, Ubuntu, or Knoppix, and is for all intents and purposes, non-responsive, does anyone know if it's actually in "Download Mode"?

[Q] Flashed wrong kernel!!!

i Was trying to get rid of the hissing noise on my
Lg g2 D802
i had TWRP installed
I read in a trhead that flashing the dorimanx kernel should fix that problem.
So i tried flash it, but instead of flashing the D802 i flashed the D800, i know i'm an idiot :/
I had a backup stock kernel but i think that's a wrong one too, again i'm an idiot
Now my phone boots into a black screen within the left top corner:
[2800] Fastboot mode started
[2850] udc_start()
i cannot boot into twrp anymore, it's basically bricked.
Can anyone help me recover my phone? i loved that thing, you will be my hero.
i promise when this is resolved i will never mess around with roms and kernels ever agian, i'm freaking out

Try to flash back to stock with kdz, as far as I am hearing this you kinda soft bricked it but not hard so it's still recoverable, you could also maybe try to flash your recovery back with fastboot since your in fastboot mode but I never tried that so I suggest you to go back to stock with kdz flashing
ye try enter download mode and follow this (use search) i think its volum up and connect usb to pc

Thank you for your reply, i tried to get into download mode, but failed every time, i can only press the power button for 5 sec and the Lg logo apears, then i get the same screen.
did this way?
Your phone must be turned off before starting the steps from this guide.
So, press power button and select “power off”.
Then, press the volume up button on your LG G2.
While you are holding the volume up button, plug in your phone’s USB cable.
Keep pressing the Volume up button until the download mode is being displayed.
Now the phone will install some drivers – it should take around 10 minutes to complete; the best will be to let your device install the mentioned drivers.

I did the same thing today by accident. I still can boot into recovery tho, TWRP. Copied the correct kernel file via OTG but it just reboots the recovery and doesn't install the kernel. Have you find any solutions?
EDIT: I actually managed to flash the right kernel and the problem is now fixed. Check everything before flashing something guys, caution

LG G2 Might be bricked, not sure.

Hello, cutting to the chase
Model: LG G2 D802
Story time: I tried to install ressurection remix rom through the sideload, after fully wiping my phone ( Wiped system, data, yada yada ) it showed some kind of an error about SU not installing properly, I thought well if I'll reboot TWRP will automaticly install SU for me, so when I tried to reboot it showed that No OS is installed, I thought it's a simple bug so I'll reboot to recovery again to check and bam. Nothing works.
+ Can't boot into recovery ( Tried volume down + power button ) LG Logo shows up and goes blank again ( Note that the screen doesn't turn off, just stays black, after holding it for a couple of seconds I can see screen going off completely but can't turn it on)
+ Can't turn it on normally.
+ Can't boot into download mode.
+After plugging it into an USB it mounts a D lettered drive with 63MB stuff in a folder called image with *.mdt files, modem files( I can screen it if it's important )
I'm clueless, never happened to me even though I flashed a lot of roms, I think I bricked it. Help?
UPDATE: I managed to quickly release Volume Down And Power buttons when LG appeared for half a second and hold it again, succesfully booted into TWRP. I haven't bricked it I think. Will tell how it goes <3
Hey man, how'd it go?
I'm in exactly the same situation as yours, can boot into twrp but nothing else works, i fear of the qhsusb_bulk brick but these people don't even seem to have recovery.
Any suggestions? Go back to stock? How?

How did it go!? I'm in a similar situation (but can boot into download-mode). Would love to get back to twrp, since I want to give it a try to flash another cm (stable). Thanks for sharing your experience...
If its picking up bulk mode normally its hard bricked there is a guide for restore nearly all g2s from hard brick having done it myself included 1st time took me a week to get back up but. Now i prob take about 45 min just cause i aint had one in a while

Hey there, can you specify what you did exactly or where to find!? Do you mean something like this? (can't post outside links, in XDA-forum, title is "LG G2 is UNBRICKABLE NOW! [FIX REAL HARD BRICK]") Thanks for help...
Yes thats it. Lol i still got the files on my pc for my g2 i keep the whe setup cause im on the g3 now i just check in the g2 forums cause i had mine for 2 years and modded the crap outa it but yea i keep all the files on hand so if anything ever happens i can fix it almost on the fly now
Well so what happened to me that I managed to get inside the TWRP. When it lighed it up for a second I quickly released and held again that got me inside magically. So then I just transfered new rom and tried to install again. Sadly I didin't see that the ROM Im trying to install requires bump TWRP and I bricked my phone again. Though I entered download mode and flashed the stock rom through LG G2 flasher.
heres a video i made, how to go into recovery. for those that cant get in to twrp.
https://www.youtube.com/watch?v=jPUTImVEHqc

Black screen, bricked, boot looped..

As the title says. My k20 is boot looping with a black screen. The LG logo no longer shows.
I had Lineage 15.1 loaded, and thought I wound make a twrp backup using Travis' Red Wolf 64bit recovery. (Greetings, fellow Hoosier)
But, that wasn't enough for me. After the backup, I wanted to try the Nethunter Kernel. I was softbricked, so I recovered the boot partition and all was fine. But, silly me figured if nethunter didnt work for me then to try out FuseBox. After flashing that, the phone rebooted into a black screen, no logo. So, now way of knowing what stage of first boot it is in.
After some fiddling, I can get it into download mode, still black screen, I only know it's in download mode because LG Up(With Uppercut) suddenly detects it. At first, it only stayed in DL mode for for a few seconds then rebooted. Durng one of those "few seconds" boots, I manage to quickly start the LG Up Upgrade process, halting the reboot. I tried flashing MP26010j and 26010k. The flashes complete successfully then reboot, but.... still a black screen and continually reboots after about 15-30 seconds..
Tips, suggestions, ritual sacrifices?
If not for the boot looping I would think that a video driver isn't loading.
alternatively, anyone know of a comparable or close enough phone under $80 usd?
Had the same problem with bricked black screen.
i fixed mine by flashing a kdz with lgup tool
Connect it to windows make sure it doesnt keep disconnecting hold vol and power buttons different ways till is stable
flashed it like 4 times till the lg logo poped up and booted up factory mode now im back to lineage/wolf revovery. Dont give up yet
I do appreciate the motivation. I just went through the process another 10 times with the 26010j kdz, and 10 with the 26011k kdz. No luck.

did you try with this and turn off real time protection https://mega.nz/#!5oxH3TwA!v7hRj5DRELer6j92X2I8zQMLxznofw37eYwZ8P_q-BM
and this kdz MP26010v_00_1214
also after i flashed it i kept playing around with removing the baterry and having different buttons pressed till the lg boot logo came on
I have the same problem, have you found a solution yet?
I have the same problem, have you found a solution yet?
I flash the stock rom m26010x and nothing
Unfortunately, no. I'm moving on and just counting it as a loss. I hope you have better luck.
