Complete Guide to LGUP 117 Patched UPD: How to Flash LG Firmware Without Errors
If you receive this despite using the patched version, you may need to select Partition DL instead of Upgrade, click Start, and then select all partitions manually in the pop-up window.
Standard LGUP software (distributed by LG) is restricted. It typically only allows updates if the device is booted into the OS or standard Download Mode, and even then, it checks for matching model numbers and firmware versions.
Download the "LGUP 117 Patched UPD" archive from a trusted developer forum (like XDA Developers). Extract the folder contents, which usually include a modified LGUP.exe and a model folder containing DLL files. Step 3: Replace the Executable
If your device is in a boot loop, stuck on the logo, or even appears completely dead (hard brick), you can attempt to unbrick it. The most reliable method is to perform a flash. To do this, boot your phone into Download Mode. In LGUP, select the REFURBISH mode, load your correct stock KDZ file, and click Start. This will wipe everything and reinstall the stock firmware. If the phone was bricked due to an incorrect cross-flash, the PARTITION DL method might be necessary to flash a working bootloader or system partition.
