Unable to find a solution to my problem. Searched and read many threads on the subject and think I've about tried everything with no luck.
Have a T-Mobile D801 phone. Took the OTA update and successfully upgraded to kitkat. Did not like kitkat so I downgraded back to 4.2.2 using the LG Mobile tool and the D801110C.kdz file. This downgrade was successful and I was able to root also with success.
So I have a stock rooted 4.2.2 phone with stock recovery.
Used the phone several weeks before playing with the build.prop file. After a modification, restarted the phone and the phone now will not boot past the LG splash screen.
The phone will boot to stock recovery as well as fully boot to download mode.
Installed newest LG mobile tools as well as the drivers, and reinstalled several times.
I have tried using the standard LG mobile tools to revert to stock. When using this method, the program identifies the phone correctly as a D801 but does not list a software version and tells me that there is no upgrade available. When click on upgrade recovery, it tells me that there is nothing to fix. So, I tried clicking on upgrade recovery without phone attached and enter the imei number and connect the phone. The software downloads the update successfully but when it attempts to install, stops at 2-3% and tells me to connect the phone. Restart the phone in download mode, reconnect and attempt again with same failure. Have tried this with swapping the downloaded file with110C, 110G, and kitkat KDZ files and all fail equally at 2-3%.
Have changed and tried com ports 41, 7, and 4 as well as disable LG modem in device manager and all fail.
Have tried this method on a windows 8 64 machine, windows 7 64 machine, and windows xp 32 machine and all still yield equal results. Tried several different USB cables and ports.
Have attempted using the KDZ with the L&D method using the 110C/D and kitkat files and the 110C/D fail at 49% and the kitkat will not even start, just errors right away. Tried this method with the different computers as well as cables and com ports.
I have also tried using the LG flash tool with the D801 TOT file and dll. Will not start and gives me error that the model numbers do not match even though it says it is a D801 at the top of the program.
At a loss here for what to try next. Any help on this would be much appreciated.
FIXED
Fixed the problem. Couldn't get any of the above methods to work. Downloaded the LG Firmware Extractor and extracted the .DLL from the TOT file and used that with LGFlashTool. That worked perfectly. Up and running again.

I have an LG Optimus Net LGL45c which I had installed CWM recovery on and flashed to stock using these instructions. Due to the way the /system/app/mover app works ( No second chances ) and my fat fingers I had to flash it again because I broke bluetooth and can't see the apps once they are moved into /data/app with the Root Browser Lite app even though I can get into the folder. Anyway, so this time it said completed and I selected back and then reboot system in CWM recovery, but it's hung on the LG screen. I can't seem to get Odin to see the phone or find any drivers that Windows XP recognizes to install for the phone. I've ran the file LGAndroidDriver_Ver_1.0_All.exe and installed those to no avail apparently, though unlock root was able to root it before, so I'm a little confused as to why Odin can't detect it, if I can't flash it without using CWM recovery it looks like it's reached it's end of life, as a phone anyway. Please, does anyone know how to flash this phone using Odin from a XP PC that would be willing to point me in the right direction? I have Odin and the stock rom from the link above but I can't get Odin to see the phone.
Thanks for any help.
No Luck.
Used all the suggested methods. Using Windows 7 and tried like a million times.
1. Restored to V21E stock Rom.
2. Downloaded the B2CApp .. The software update tool doesnt go beyond Analysis. Says Problem Connecting Phone and restarts till it allows the exit button.
3. Used the method where I enter the IMEI number, here the tool goes beyond the download phases and crashes at the update phase.
4. Tried using the Offline method but the tool doesnt go beyond the connection phase in this too.
5. Tried using direct update method on the UpTestEx tool either by CDMA or 3G but the tool crashes at extracting KDZ.
Current Stage :
1. MSXML installed
2. B2CApp Tool Installed.
3. All Drivers Installed.
Please guide me towards successfully updating the V21Y baseband with 2.3.4

I have seen cases where the USB cable itself is the cause of the issue. For sh*ts and giggles, have you tried using another cable?

I got a LG g3 I flashed CM13 wrong im guessing now im stuck at the loading screen for CM 13, I cant boot into recovery due to my volume down button not owrking. I can boot into download mode. I tried to do a factory restore with LG Flash Tool with stock dll and such but when I do that I get a error cant go into download mode. I tried switching ports and switching cables. I tried reinstalling multiple drivers still no luck. Please help me. I am using Windows 10. I tried running LG flash in combat mode for Windows 7
You need to plug in the phone and then go to settings/device manager and verify device drivers are installed. If not download them and it will find the phone.
Have you tried going into recovery via fastboot?

I am trying to update my lg v450vm from android 10 to 11.
It is running stock Verizon V450VM20f
I downloaded V450VM30b_00_VZW_US_OP_0120 KDZ from the LG site along with LGUP, Uppercut and the LG USB drivers. I installed the USB drivers and LGUP.
I place the phone in download mode and run Uppercut.
Uppercut recognizes my device, I select the upgrade button and then the KDX file.
When I press start, the progress bar shows 4%, the title bar says USB connection established and then Uppercut closes.
Running on Windows 11
Any thoughts?

Edit: Title should read flashing stock firmware

Solved.
My problems was that I had to download a common.dll file for LG and place it in the common folder for LGUP. The update went well to 11. Cant wait for a 12 KDZ to be released.

Hello there, I am currently on V450P20n with Android 10 from Sprint..Bought the unit from eBay and I am currently using it in Guatemala. No updates or anything since July 11th 2021. Is there a step by step guide of how we can go ahead and get Android 11 (Stuck, not Custom ROM) ? I had some experience back in the days with Samsung and Odin to flash some OEM ROMS, and I love how this cellphone looks. He is a keeper.
Anyways, any help would be appreciated!
