Hello,
I have a lg g pad 8.3. Today I've tried to do the downgrade Lollipop -> Kitkat, but something wrong and I have the boot logo restart. But I've put my G PAD in download mode and now I'm trying to install various version of stock version through LG Flash Tool. But on my Windows 10, I receive the error "LGUserCSTool LG Mobile has stopped working........", while on my Windows XP pc, the .kdz of the version 30a.kdz stop the installation at the 95% and the LGMobile Support Tool tell me to retry the installation, while with the version 10b.kdz, finish at the 45%.
What I have to do now?
I see only DOWNLOAD MODE on my tablet, If I shutdown the tablet, reappears the Download Mode, no LG Logo.
Sorry for my bad english.
I followed this guide but used the 10b.kdz instead of 30a

I noted that using 3GQCT worked fine (but required a hard reset)
CDMA caused "LGUserCSTool LG Mobile has stopped working"

Dear All,
May I ask a help for my G Pad.
After flash the rom , my g pad stay in LG logo,
I tried using download mode , In PC the LG mobile tools show "Waiting connection" but the firmware version can show "10018A upgradable".
When I click option --> upgrade recovery in LG mobile tools , its pop up a Model and SN, even I entered ,it also cant do a recovery.
Confirmed that I have install LG G pad driver in windows.
Also I tried a factory reset , after reboot also stay in LG logo.

Are you sure you're in download mode when you run LG mobile support tool? I was in a similar situation last week and it worked flawlessly for me. Follow these steps to get into download mode:
With Device Powered Off And Unplugged
Press and hold Volume Up + Volume Down --> this gets you in download mode
Now Plug In USB Cable --> after this, LG tool should recognize your pad
Alright, now i'm going to show you how to flash LG G pro lite using LG flash tool, this method does not required internet connection (offline).
So basically you need to download the kdz firmware for LG G pro lite and LG flash tool, this way you can flash your phone offline.
You maybe asking, why do i need to flash my phone? well here's some reasons why you want to flash your LG G pro lite:
your phone stuck in bootloop
you want to completely unroot the phone
you want to upgrade from jelly bean to kitkat
you want to downgrade from kitkat to jelly bean
your phone runs very slow and you want fresh install
you want to sell your phone
Remember that this is a DWYOR tutorial, means do with your own risk, this flashing method is tested successfully by me, but i'm not responsible if you damaged your phone.
Here's all the ingredients for this tutorial (stuff that you need)
LG united mobile driver,
LG G pro lite kdz firmware
LG flash tool 2014,
Visual C++ runtime
Computer running windows ( i use windows 7)
The LG G pro lite itself
Micro USB cable
Donuts and coffee with less sugar
Courage and confidence
Okay, after you get all the ingredients, we can begin to flash the phone, and don't forget to backup your data first, because all data inside internal memory will be gone after flashing.
Step by step how to flash LG G pro lite
install LG united mobile driver
install Visual C++ runtime
run LGFlashTool2014.exe
select type "CDMA" and phone mode as "DIAG"
select the kdz file (the firmware that you're going to use to flash the phone)
put the phone into download mode, read my previous article if you don't understand
click on "Normal Flash"
click ok on "select country & language" window
wait until the whole process finish
It's actually very easy to flash LG G pro lite offline using LG flash tool, now you can go from jelly bean to kitkat back and forth.
This flashing method could also be applied to other LG smartphones that runs android, such as LG G3, G2, G2 mini, etc.
NOTE
when i was flashing my G pro lite dual from kitkat 4.4.2 to jelly bean 4.1.2, after finish flashing i got stuck on boot logo, i solve this by doing factory hard reset and the phone boot normally.
make sure when you plug the phone to computer (download mode) there is no error message, install the latest LG united mobile driver.
it is recommended that you do factory reset before flashing your phone.

Hello everybody, I got a G3 D855 (european version) of 32 GB with Lollipop 5.0 stuck at bootscreen. I have never tried to root it.
I have tried hard resets, LG Flash Tool, KDZ Software Update, BoardDiag, LG Mobile Support Tool and LG PC Suite on Windows 7 Starter (32 bits), but anything worked.
I got problems with the driver LGE Android Net MTP Device wich never installs fine and gives me errors. This driver and the driver LGE Mobile Novacom (both updated) say something like "This device can't launch. (Code 10)".
How can I fix my G3?? (My main language is Spanish). Please help, I need my phone working asap

Hi,
I tried to upgrade my LG G4 H815P with this thread:
https://forum.xda-developers.com/g4/development/h815-nougat-stock-locked-bootloader-t3709119
The process with LGUP was ok (upgrade mode), but after the first reboot the phone stucks on LG logo, so I tried to use refurbish mode but the process throws a error 0x2000.
I tried a lot of solutions but the problem continues.
Maybe you know a tot file with android 6 to restore my phone with LGUP?

https://forum.xda-developers.com/g4...bootloader-t3709119/post74946652#post74946652
Seems like the restore only works with H81520p_00_0314.kdz
Solved!
Hello!
I'm quite new to the android rooting scene, so I encountered this problem on my LG G Pad 8.3 (v500)
I had installed Lineage OS with android 7 (can't remember exact version) and tried to root the device

I tried getting into download mode, recovery mode, adb, flashing stock rom, but none worked. They all lead to the same error. Best result I could get was with download mode: the lg logo for a few secs, and then a black screen
Is there anything I can do to unbrick my device?
we are two with the same problem
