LG UP version 1.15 is known to have slightly looser checks than newer versions. If you are using v1.16 or v2.0, downgrade to v1.15.
Where to find it: Archived LG developer tools or XDA forums.
Installation:
If you still see error 0x5319 after trying all six methods, the KDZ file is likely completely incompatible with your phone model. Find the correct firmware using your phone’s exact model number (e.g., LM-V600EA for LG V60 EU version).
If none of these solutions work, the error may be specific to your device's current software state. You may need to visit an LG authorized service center or contact LG Support directly.
Issue Report: LGUP Error 0x5319 typically occurs in the when a user attempts to flash a firmware (KDZ) file that is incompatible with the device's specific region or carrier variant. It is a security/software guard preventing unauthorized "crossflashing" or changing the device's identity. Technical Definition Error Message:
Error 0x5319, not allow to change the device (Region_A > Region_B) lg up error 0x5319
The LGUP tool detects a mismatch between the current firmware on the phone and the target firmware being loaded. Common Scenarios:
Attempting to flash a US T-Mobile (NA2) firmware onto a US Verizon (NA5) variant.
Attempting to "Refurbish" a device with firmware from a different region to remove bloatware or unlock features. Root Cause The LGUP software checks the device's
and existing regional code. If the target KDZ file contains a different regional identifier (e.g., changing from NA2 to NA5), the tool aborts the process to prevent a soft brick. Recommended Solutions Verify Firmware Compatibility:
Ensure you are using the exact KDZ file meant for your specific model and carrier.
You can verify your device's original firmware by entering your IMEI on specialized databases like to retrieve the correct software. Use the "Partition DL" Method: LG UP version 1
Instead of "Refurbish" or "Upgrade," some users bypass this by selecting Partition DL
. This allows you to manually select which partitions to flash, which can sometimes bypass the regional check, though it carries a higher risk of bricking the device. LGUP Patched Version:
Standard versions of LGUP are highly restrictive. Users often require a patched version of LGUP (such as version 1.16 or 1.17) that includes the UI_Override features to allow cross-regional flashing. Driver Check: Ensure the latest LG Mobile Drivers and the correct common.dll
file for your specific model (e.g., V60, Wing) are installed in the LGUP directory. LGUp Tool 1.16 PATCHED for the LG Wing Tutorial
The error "LG UP Error 0x5319" typically occurs when using the LG UP flashing tool on LG phones. It generally indicates a model or DLL mismatch between the firmware (KDZ) you are trying to flash and the actual phone model, or a problem with the phone's partition table.
No. This is strictly a software verification error. Your phone’s hardware is fine. If you still see error 0x5319 after trying
If you are getting error 0x5319 with full KDZ, try using Partition DL mode (available in LG UP patched).
Steps:
This method bypasses the full model check because you are only writing specific partitions, not the entire cross-flash verification.
Error Code 0x5319 typically occurs when using the LG Bridge software on a PC or the Software Update feature on the device. This error indicates a network connection timeout or an interruption in data transfer between the LG servers and your device.
In most cases, the error message reads: "Unable to download software update. Error code: 0x5319."
