LG V20 stuck in firmware update - LG V20 Questions & Answers

So, I am a complete know nothing when it comes to software on phones but I'm desperate. I have an LG V20 that started an update and froze, I can't find any fix for this. I've removed the battery, I have used the LG Bridge error recovery, it hasn't worked. I cant get to the android recovery mode. I've heard about LGUP but I can't get it to work. If someone could walk me through that I'd appreciate it, or if there is a better solution.

Try to see if you can get it in to download mode if you can then download a kdz file and flash it with LG UP.......

[Q] Sprint LG G2 Bricked by Custom Recovery

Sorry to bother everyone, but I am in a really sticky situation here. I don't know much about rooting and recovery, and have run into a real issue, so I will try to explain as best I can. I rooted my phone no problem and installed a custom recovery that didn't work at all, so I left it and forgot about it. Today, I tried to update my phone but when it rebooted I simply got the message: [830] Fastboot mode started then below it says: [830]udc_start() and will not advance. I cannot do anything with the phone when I plug it in nor can I access any of the files aw it doesn't seem to be recognized, and when I boot into recovery I just get the screen with the same message. I tried putting it into download mode, but it just said 0% and no messages about drivers or anything popped up onto my screen. I am in a real pinch here fellas, and I really hope you guys can help me out. Thank you all in advance.

You have to read carefully.. Do as it says.. It works.. You have to download the right drivers and then get it in download mode and then flash stock rom... I don't have the time to tell you every step but that's what needs to be done

Here are a few screenshots that can help you guys identify the issue. First is a screenshot of the lg support tool, which recognizes my phone as a "testmodel"
The next is an image of what happens when I try to upgrade recovery.
Also, the lg mobile support tool doesn't even have the ls980 drivers. Can anyone give me instructions on where to go from here?

Thank you everyone, the issue was fixed! After verifying the files, looks like I picked up the wrong TOT file. Had so many of them downloaded over trying to fix this I confused them . Thank you for all of the help, I truly appreciate it. I'm not sure if I am supposed to close the thread or if a moderator will do it or what the protocol is, but consider the issue resolved .

[Q]How do you fix Lg Optimus L3 on bootloop?

I have T-Mobile LG Optimus L3 that was rooted with Kingo without a recovery (I'm a noob). A while ago my phone became irresponsive so I hard-reset it( also because I'm a newb). When I was done, my phone was stuck on bootloop. It would get to the white T-Mobile screen then loop there. I tried using the LG Mobile Support Tool but an error would occur at 4%. I don't know what to do. Can you please help.
It's no big deal.

Try using the KDZ method to flash your phone. So it will be back to it's stock ROM. You can find the KDZ update method here
PS. If you still have doubts I could walk you through. Cheer up!

OKay. So you tried out differrent things. But if you could explain briefly why the KDZ did not work for you, it will be much easier to solve the puzzle.
Could you get your phone in emergency mode?

I don't know why kdz do not work, i had never seen this, I can put on Emergency Mode but, when KDZ finish flash the phone splash a white screen and back to LG logo, adb says only "device not found" , and fastboot says <waiting for device>

If the phone is not turning back on even after the KDZ update, then chances are that you have hard-bricked your phone. In the KDZ update, does the log says 'UPDATE SUCCESSFUL' message?.

"Wparam=100; Lparam=6" are errors denoting that the update was not successful. And the 'finished' message indicates that the process is complete. But, it must show that "Update Successful' in the log. Understand that. Try to re-install the LG mobile drivers and then flash it.

LG G2 used

So I've just bought a used LG G2 D802 32GB and the rootchecker app shows me that it has been rooted. I'm trying to find a way to make it completely stock, unrooted again so that my warranty would work. I've found that I need to flash .kdz file. I tried getting into download mode(plugging in USB cable while holding volume up), but unsuccessfully. Should I do anything before flashing? Should I somehow make a backup? Do I need to install TWRP before doing that? Or maybe I already have it, I don't know Any advice would be helpful.

Don't worry! We'll get you fixed.
Please give me around 20 minutes and I'll extract a few partitions for you to flash. In the meantime, get back to fastboot and plug in your phone to the WALL CHARGER, not PC.
P.S.: LS980 Cloudy fixpack users should see an update soon!

Carrier does not really matter on F320, I guess. I am having refurbished F320 which had F320K parts and my it was saying F320S under the battery.

Fastboot commands received but not executed

Firstly, my phone [D802] will only go into either
1) fastboot mode (not download or recovery)
2) a white screen with three options in korean (yes/no/cancel?) showing a barcode with my IMEI number
The fastboot command shows a '?' for my device identifier, and when I type a command, the phone displays the command, but never seems to perform any action.
For example, "fastboot reboot" just sits there until I quit the command. This is the same for "erase" and "flash" commands.
"getvar all" returns immediately but never shows a response.
I have tried various versions of LG united drivers and google drivers on two different windows machines and a mac, all with the same result.
I would be grateful if anyone could suggest what to try next.

I had to restart the flash tool many many times, each time it reached a slightly higher percentage. If you rerun the flash, does it always fail at 2%?

When you purchase the phone, if it came with android Kit Kat of D802 then you can install without problems the KDZ that I mentioned to you, because if the Kit Kat version is aptavel so jelly bean also is.
