Hello,
I want upgrade my LG G2 with a new rom 5.xX
This phone have only the operator update. No custom, no trwp, nothing...
I installed drivers and when i want access to download mode. I can't. I use the good proccess with vol up then plug usb cable always with vol up presses.
follow this procces after a little moment my phone show me battery logo charging.
So i can't access to download mode.
I would use this process
t was NOT bricked. I finally tried playing around with the LG Mobile Support Tool (B2CAppSetup.exe). Of course it detected that my phone already had the latest firmware from T-Mobile, but then I clicked Options>Upgrade Recovery.
It downloaded for a while then I noticed it had put my phone into download mode (it said "Rooted" in red letters at the bottom). Then it flashed the same firmware over and I immediately tested, it entered download mode right away. But I didn't end up needing that as Stumproot was able to brute force it now after the recovery flash.
Anyway, I couldn't find an answer anywhere else. Most results also have a bricked phone, but that wasn't my issue. This solved my problem and maybe it could work for others.
but it's impossible for me to install B2appsetup on my pc the installation begin then stop after 5s then nothing.
I have Win 10.
Do you have a solution for me , please??

Hello guys,
So I bricked my D802 , how? first it was bricked because of a wrong version of TWRP, untill here no problem, i tried many tutorials on how to go back to stock rom, then i found that it was a Qualcom thing problem, so I found that tutorial about replacing the .img files etc... , pretty easy, i could enter the recovery menu, but it had no rom, i downloaded the stock rom kdz file , started flashing it, then, for some dumb reason the flashing stopped, I ... plug out the usb cable... I didn't notice untill I saw that the program froze, and now the phone is stuck at the LG logo, impossible to do anything, pc doesn't recognize it, can't go to recovery menu, can someone help me please? or at least tell me if I should just throw that phone or keep it if it has a chance of living a bit longer

I had a very similar problem with it getting stuck at the logo after pushing supersu to the phone. I followed Supersport every single step of the way in his video. I think his links are the only valid ones online now, so just download them and reflash your phone. If your G2 is anything like mine, drivers will never appear to be installed correctly and it never restarts, only shuts down.
His method is:
1) Download and install LG drivers on PC
2) Download and install the flash tool and patch it
3) Download and load the .tot and .dll files into the flash tool
4) Enter download mode on G2 by holding volume up while connecting USB
5) Switch G2 Com port to 41 in device manager
6) Once Flash tool shows that all ports are ready, power down G2 and disconnect
7) Hold volume up and reconnect to get back into download mode
8) LG Flash tool starts flashing
9) Complete
Note: If your G2 was screwed up as bad as mine, it'll say failed but all the main system files will load to the device before it restarts and it'll even shut itself off while doing it's installation on first reboot. Mine somehow was still revived from this state with his method.
I was trying to update with LGUP application for firmware update but didn't success, so I removed the USB cable and pressed Volume down and power button to restart. But it went straight into Firmware Update and LGUP application can't find the port.
So, my phone is stucking in Firmware update screen, please help me how to restore the firmware and get out from Firmware Update screen, many thanks and greatly appreciated.
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.
Enter download mode and connect the phone in the PC. Download LG brige and open it. When you are inside the programe you will see a window of Software update enter here and there is an option that is for bad installation otas (to reinstall and correct errors). Use this and I think this will handle.
Another option I think is using LG Up you will see your device in download mode. Try to enter download mode and see if this works also.
Thanks both - I ran into a similar situation. I pulled down both the 11a and 14a KDZ files, and used UpperCut and LGUP to flash first the 14a and then the 11a image. Unfortunately in both cases after LGUP does its thing, I'm getting the LG logo, followed by fastboot screen.
I cannot reboot to get past it, and I cannot flash recovery (it says the boot loader is locked). I cannot flash the Unlock.bin from LG because apparently the KDZ re-enabled the software lock prohibiting bootloader unlocks.
So I'm suck with a phone that will only boot into fastboot, stock recovery or into download mode, and I cannot figure out how to get back to something functional. I've tried reflashing with LGUP - that doesn't work. And the LG Bridge "Update Error Recovery" option gives an error "Connect your mobile device to the USB Port" even though it is, and the LG USB drivers are installed.
Would appreciate any pointers someone could offer.

I have the same issue - I was on Lineage os and flashing the OTA update caused bootloop to recovery. So I wanted to flash back to stock using LGUP and 14A. I did that before without issues.
This time though all installed fine but after reboot the phone immediately goes to fastboot, exactly as described above. I just spend several hours trying to fix it but with no results. The LG Bridge won't recognize the phone no matter what I do in Windows (tried 3 different PCs). On a Mac it will start connecting and will end up saying "you need to enable MTP connection".
From what I garther the stock rom flashed fine - the factory reset works, even shows "erasing data", the LG UP recognizes the phone as 14A (I tried 11A, 13A too - seems to install fine but goes immediately to fastboot after reboot).
The only thing I realized I did different when flashing the stock rom with LGUP was not using the original LG USB cable. But reflashing with original cable makes not difference now - still going to fastboot.
Any help would be greatly appreciated.
Have you guys been able to do the Upgrade recovery in the LG support tool? Did it work? It starts fine for me but after downloading the recovery file I always get and error, see the screenshot.
I was able to grab the kdz file and tried to flash it with LGUP but still the same thing. It seems like it flashes fine but after reboot it immediately goes to fastboot

Sadly I'm in the same boat as well. I'll pull some of their error messages I've gotten with LG Flash Tool this afternoon. I've tried 2014 and 2017. Both to no success.
I suspect it may be something with the /misc partition. Im going out on a limb, but I'm guessing that the AOSP and Lineage ROMs may touch misc. That partition may have some key identifiers for the LG tools. And the KDZ doesn't have a misc partition embedded inside it.
I was hoping the kdz file I was able to grab from the Lg Support tool would be different from regular stock rom 14a that is available around the internet but it appears to be exactly the same file (based on the file size). My original hope was that the file would support "Refurbish" option in the LGUP tool but it only works with "Upgrade".
I wonder if the "Refurbish" option would fix this and re-flashed all partitions - if only we could find a kdz file that would work with the refurbish option. So far all files I tried (11a, 13a, 14a) only support the upgrade option.
Thanks for all of your helps, I used LGUP and WondersMobile application on the computer and LGUP can not see the port. I did un-install the WondersMobile and LGUP can see the port and finally upgraded to latest firmware.

I too am having same problem. I've tried all the images from 11A to 14A, all of them flash with no errors on LGUP and every time LGUP detects the phone as having the last version flashed. Unfortunately, the phone also boots to fastboot every time. Nothing else to add to your descriptions at this time I'm afraid...

I am absolutely positive my problem is at least in part due to a messed up /misc partition though. @gqo actually described what I did pretty thoroughly in his thread, albeit in a G5. Post #9 has the fix but it didn't work for me.
I've also stumbled upon a menu under the Firmware Update screen that I had never seen before and cannot fin any mention to... Would any of you guys know what it is for? It reads something like:
Code:
** SELECT MENU **
** Select : Power Key(Long) **
** Move : Power Key(Short) **
-> MA-USB(WIFI) DL
POWER OFF
PHONE INFO
BACK
Okay, I figured it out. The menu, at least the first option, appears to be for Wi-Fi firmware update. I wonder what file the phone actually downloads... And if it would be able to fix our phones. The only unprotected network I had in hand was a mobile hotspot in my not-so-LTE Nexus 5, so I got as far the firmware download start but didn't risk it on such a slow and unpredictable network. On top of that my Nexus 5 has also gotten pretty good at bootlooping, that's why I got this G6 in the first place. If anyone out there has a reliable unprotected network and nerves of steel it could be interesting to see if the outcome of this update is different from the LGUP one.
How do you access this menu?
What I started working on yesterday is trying to build a image file for the Qualcomm Flash Image loader and see if I can flash the phone using this tool... But I have never used this tool before, right now it does not detect my phone - I need to work on that + see if I can correctly build the image file from kdz. I found some youtube step by step tutorials so we will see. I will post update on the progress tonight or tomorrow.

I'm not sure if there's a better way to do it, but I access it by removing the usb cable after I successfully get in Download Mode. Then I'm not sure if there's any specific key combo, I've been randomly pressing the power and the volume down buttons and at some point I get into that menu. In the menu though, for some reason, I think I can only select an option if I long press both the volume down and power buttons. The "POWER OFF" option has come in handy because so far is the only way I can actually turn my phone off. The "PHONE INFO" hasn't worked for me yet. The menu also reacts when you add/remove the microsd card... I wonder if it can be used for something other than a WiFi firmware upgrade. I haven't had the chance to connect the phone to a computer to see how the device is recognized, if at all.
And that image you're working on sounds like a neat idea, I wish I could help but I'm afraid I wouldn't have the skill. I may be able to test though. Anyway, Godspeed!

I'll play around a bit and see if I can land on this menu. At this point I'll try anything. I'm on an iPhone until I get this fixed - so I'm motivated!
I can setup an open guest network off my main wi-fi this evening and see what I can find out.
EDIT Sorry, I tried playing around here, but I couldn't figure out how to get back into the the menu you uncovered. If you could give some instructions on how to do it, I'm happy to give it a shot on my device.
I was able to access the menu today...what worked for me was at the firmware screen unplug the usb cable and then press volume down and power button three times quickly. I tried to connect to a wifi and it does not really do anything. I think it just establishes wifi connection but it does not download anything on it's own - it's waiting for another connection.
Also I got stuck with building the image file from kdz, it has no information on partitions. At this point I decided to ship to LG for a quote and will see how much they will ask for a reflash.
I got as far as selecting a network and getting some sort of a download start screen, but I interrupted it right away so I wasn't sure the download would actually go through... Apparently it does not. If this menu has some sort of flashing capabilities though, it might be worth checking how secure it is. If someone can get it to download and flash a modded file perhaps there could be a chance of flashing a custom recovery or something... I'm thinking about those guys that have an unlockable bootloader (which we ironically also have now).
Anyway, all of this goes well beyond my skill so I followed your example and submitted a repair service request to LG. It'll take quite long but shipping is free, so I figured I'd give it a try. I'm assuming this is an easy fix with the right software tools, so I hope LG doesn't overcharge for it. I'm even half hoping they'll do it under the limited warranty... If I recall correctly unlocking the bootloader doesn't immediately void all warranty, there's room to prove the bootloader was never actually unlocked. And after all LG does say that once unlocked, it cannot be undone and our phones are, in fact, running stock firmware and have a locked bootloader.
Update: My phone was received today by LG. In LG's Track Repair page, the status briefly showed as Undergoing Diagnostic but quickly moved to Repair In Progress, it's current status. Given that LG was supposed to contact me in case the repair was not covered by the limited warranty, meaning that an extra fee would've to be paid, I'm assuming the phone will be fixed (if possible, that is) free of charge. I will update you guys again soon, but if anyone out there is still struggling with this issue I'd recommend considering sending the phone to LG.
I have the exact same problem. Please keep us in the loop of what happens to your phone with LG
My phone has been received by LG for this issue on 9/26. It quickly moved through diagnostic to "repair in progress" on the first day plus showed ETA back to me in 6 business days. Ever since that it's stuck in that mode, no update or contact from LG. I check the status every day - every day it says the same - ETA 6 business days. It's been a week and half now with no update. I kind of expected it's going to take 2-3 weeks but annoyed that they say 6 days ETA and then you don't hear from anyone for almost 2 weeks with no change in status.
Update #2: The status finally moved to Shipped To Customer. I haven't been contacted by LG yet, so I guess the phone could've been shipped fixed as much as it could've been shipped as is for being unfixable. Either way, I wasn't and most likely won't be charged. FedEx hasn't got an ETA for the delivery, but I'll let you guys know as soon as I get my phone back.
Edit: Got an e-mail from LG. It reads something like:
Defect: Software failure
Payment Type: NOT APPLICABLE
Repair Results: S/W upgrade (download)
Repair Cost: $ 0.00
Warranty Status: In Warranty
Tax: $ 0.00
Total: $ 0.00
I guess I got away with it, I hope you guys do too.

After installing an unofficial build of Pixel Experience and having some issues with it i decided to flash my G6 back to firmware, but when tried doing it with LG UP i kept giving me Error messages about DLL's not matching each time i did it and it was weird to me cause i flashed it to firmware before with all the same files and it worked just fine, i tried LG Bridge but it won't install as it's stopping at 14%, my G6 is now on the Frimware Update screen, when i reboot it by pressing Volume Down + Power Button it shows the G6 Logo and boots straight back into Firmware Update, any ideas what im supposed to do at this point?

Have you fixed the phone ? If not I can provide you tommorow with the exact files you need to get your device working, but mainly you need for lg up the lg v40 dll so your device can be recognized and then you need a kdz file ( stock software ) that you care going to flash on your device.

Get the dev patched LG UP from this post:
https://forum.xda-developers.com/showpost.php?p=76510671&postcount=168
and get the KDZ firmware specific or compatible to your phone from the lg firmwares website (just google it for the website link). You should still be able to enter download mode. Start LG UP on your PC and connect USB cable to the phone. then restart the phone by holding vol-down and power buttons, once the phone screen flickers and it starts restarting, let go of power and vol-down buttons and hold the vol-up button. You should now be back in download mode. Good luck.

This error is probably due to older dll, you are still using the older LG UP still installed on your computer. Remember, to use the Dev patched LG UP, you just unzip the file you downloaded and go inside the folder and doubleclick on the LGUPD.exe to start it.
If that doesn't work, need more information:
Did you uninstall all LG UP before installing Dev patched LG UP? Make sure you uninstall all LG UP from your PC and then use the Dev patched LG UP directly from the downloaded folder. Make sure you reboot the computer afterwards before trying. Try different USB cable if you have one. Try different USB port on the computer.
Make sure you are opening/using the LG UP you just downloaded. Which option did you pick in LG UP? Try Partition DL or Refurbish, both options if either works? Do not try any options that you don't know about, some options can delete everything on phone including IMEI information so don't try options such as chip erase.
What is your phone's model number and which kdz are you using? Does 0x2000 error give any more information on the popup?
If none of this works, post back here.

What is your phone's model number and which kdz are you using? Does 0x2000 error give any more information on the popup?
If none of this works, post back here.

I've tried the provided dev lg up on a whole different pc, and that's the error im getting so im 100% sure it's not due to an older lgup, in the error message it shows that it's some kind of dll problem and i should install a new package .msi, i've tried different cables, ports, i did Partition DL & Refurbish, got 0x2000 both times
Hey everyone,
I'm very new to Android development and XDA, but a few years ago I bricked this LG G2 and I don't really remember how, except that I rooted it and tried to install a custom ROM, which obviously didn't work.
I have tried a number of different guides on these forums, but somewhere or another I get stuck on them.
[HOW TO] Fix your soft-bricked LG G2 (All Variants)
I'll be very specific, something most people lack of. Okay lets get to it, I recently bricked my LG G2 (D801) by installing a ROM that wasn't compatible with my model. I fixed it by doing the following steps. This worked for me using Windows 8.1...
forum.xda-developers.com
With this one, although the device shows up in Devices and Printers, neither Fastboot nor the LG Flash Tool detect it. I have installed both the LG Mobile Driver and the LG United Mobile Driver.
“./fastboot devices” is empty.
I have the TOT file and the DLL that the (patched version of the) LG Flash Tool requires.
I have an Ubuntu 20.04 install as well as Windows 11. I can get into Firmware Update with a USB icon ("Do not unplug the USB connection until the process is complete. 0%." ...etc), when I turn it on normally it shows a battery made out of grey and white bars and a percentage, and sometimes the LG logo.
If you need to know anything else don't hesitate to ask \
Much appreciated,

use a usb 2.0 port, update adb/fastboot, update drivers, remove previous related devices using nirsoft usbdeview. try using a windows 7 or earlier system. can you manually get into recovery? if so update to latest blastagator twrp which should be 3.3.1.

- I was using a 3.0 port, although it still showed up in Control Panel - I’ll try with a 2.0 port today
- I installed “Minimal ADB and Fastboot” and the drivers yesterday, so they should be up to date
- I’ll use usbdeview too
- I can’t use an older system unfortunately
- How do I get into recovery?
Recovery: With the device powered off and usb unplugged, hold Volume Down + Power. When the LG logo appears, release both buttons and hold Volume Up + Volume Down.
Ok, so I got into a factory reset screen that way, I said yes to factory reset, is that the right thing to do? (@DvineLord)
ADB recognises the device, but it's unauthorised. And I obviously can't boot it up to authorise it.
Factory reset just got me back to the LG screen for a long time, so I powered it off again.
Also, when I try to change the COM port to 41, when I click Advanced in Port Settings, it just stops me with "You must have write privileges in the registry for this device in order to modify the device's advanced settings".
I can't find the right path for the device in regedit to follow these steps: https://forums.techguy.org/threads/need-write-permission-for-com1-port.577543/#post-4756991
Were you able to get into Recovery? or did you get into Bootloader/Fastboot/Download?
Bootloader/Fastboot/Download: With the device powered off, hold Volume Up and connect the USB cable.
You want to be in Recovery like I posted above. Do you have TWRP on your device?

The recovery method you said to try got me into a factory reset screen, as I stated. All the other recovery methods I saw online didn’t work, so maybe I have no recovery?
I said in the original post that I can obtain download mode. I recognise “TWRP” but I’m pretty sure I botched it up while installing it, because I didn’t know how any of this worked, 4 years ago.
Thank you!
Unfortunate you can't get ADB/Fastboot working.

Soo... what can I do?
Try to recall as closely as possible the exact steps you used to modify your device. autorec, ioroot, stump root, avicohh, stock build you were on, custom rom you tried to flash, custom recovery, bootstacks, custom kernel, etc.
Odds are you'll have to try again to flash back to stock, something which I haven't done yet.
Unfortunately all I know is that I tried to install a custom ROM, scuffed up when I was installing twrp, the ROM didn't work and now I have no recovery to fix it. Flash back to stock *is* what I'm trying to do (that's your third question/point which I've already explained in the original post).
If anyone with the same problem visits this in the future, please save this post and share your solution if you find one, cause I'm still stuck!
hope you get it flashed back to stock. make sure to do the first 5 things i listed in my initial post to see if that helps you flash back to stock. the data cable can also make a difference sometimes too.
