How to Setup and Use LGUP Tool

Follow these standard engineering steps to safely execute firmware operations using LGUP Tool on your Windows PC:

1

Download and Extract Archive

Download the official zip file from the mirror above and extract it into a dedicated folder on your local drive (e.g., C:\tools-lgup\). Avoid deep paths with spaces or non-English characters.

2

Install Matching USB Drivers

Ensure the appropriate Windows USB driver for your target device and chipset is installed. Check our USB Drivers Hub for official manufacturer installers.

3

Launch Program as Administrator

Right-click the main executable file inside the extracted folder and select Run as administrator to grant required raw USB port access permissions.

4

Load Official Firmware and Connect Device

Load your official firmware package into the interface, boot your phone into its specified flashing mode (Fastboot, Download Mode, or EDL 9008), and connect via an authentic OEM USB cable.

Frequently Asked Questions

What is the difference between Refurbish and Upgrade mode in LGUP?
Upgrade mode installs the new KDZ firmware while preserving user data and settings. Refurbish mode performs a clean full factory wipe, erasing all data and restoring the device to its pristine out-of-the-box state.
Why does LGUP say 'Unknown Device' or fail to detect my phone?
This usually occurs if the LG Mobile USB Driver is missing or if the required LGUP DLL (or UPPERCUT) is not registered for your specific model. Ensure your phone is in Download Mode before opening LGUP.
Can LGUP unbrick a bootlooping LG device?
Yes. If your phone can enter Download Mode (hold Volume Up while connecting the USB cable to your PC), LGUP can flash the official stock KDZ to resolve bootloops and software corruptions.
