Check KDZ ARB using LG Firmware Extractor or WindowsLGFirmwareExtract:

If KDZ’s ARB < phone’s ARB → cannot flash.

Example: If flashing an LM-G710 (LG G7), use DLL labeled for that model family or “uppercut” DLL provided by community guides for that generation.

Error 0x5319 is a CrossDL mismatch error. It indicates that the firmware you are trying to flash does not match the expected model or region of your phone.

In simple terms: The tool reads your phone’s internal model ID (e.g., LG-H930) and compares it to the model ID inside the KDZ file. If they don’t match exactly, LG UP refuses to proceed and throws error 0x5319.

Sometimes, error 0x5319 is caused by a missing or incorrect LGUP_Common.dll.

Fix:

This DLL overrides the model verification process.

Advanced users can trick LG UP into skipping the model check by editing the Windows Registry to change the device model reported to the tool.

Steps:

Example: If the KDZ is for H930 but your phone is H930DS, change the value to H930.

Note: This does not permanently change your phone—only how LG UP reads it. lg up error 0x5319

The official LG UP is strict. However, the developer community created a patched version of LG UP that disables CrossDL checks. This is the most popular fix for error 0x5319.

How to do it:

Warning: Bypassing CrossDL can hard-brick your device if you flash completely incompatible firmware (e.g., LG G7 firmware on an LG V40). Only cross-flash between closely related variants.

Let me know your exact LG phone model (e.g., LG G8 ThinQ LM-G820UM) and current firmware version, and I can give more specific steps.

Region Mismatch: Attempting to flash a different region's firmware (e.g., trying to put a US firmware on a Korean model).

Cross-Flashing Restrictions: Newer LG security prevents "Refurbish" or "Upgrade" modes if the ID does not match.

Corrupt KDZ: The firmware file itself may be incomplete or for a slightly different sub-variant of your phone. ✅ How to Fix It

To bypass this error, you usually need to use a specific process often called the "Partition DL" method: Use LGUP with "Partition DL" Open LGUP and select your phone.

Select the Partition DL radio button instead of "Upgrade" or "Refurbish." Click Start. A popup will appear with a list of partitions.

Select all partitions and click OK. This forces the tool to overwrite the region-locked checks. Verify your KDZ File

Check your exact model number (e.g., LM-V600VM vs. LM-V600EA). Enter Download Mode on the phone:

Use a tool like LGROM.com or LG-Firmwares and enter your IMEI to ensure you have the 100% correct file for your specific device. Check LGUP Version

Ensure you are using a "patched" or "developer" version of LGUP.

Standard retail versions often block cross-flashing entirely. Look for LGUP 1.14 or 1.16 patched versions on forums like XDA Developers. ⚠️ A Note on "Good Paper"

In the context of LG flashing, "Good Paper" usually refers to having a clean IMEI/ESN or a device that isn't blacklisted. If your device is "Clean," the software should technically allow these updates unless the bootloader is specifically locked against the version you are trying to install.

If you continue to get this error after trying Partition DL, it means the firmware is strictly incompatible with your hardware's internal ID (e.g., trying to flash NA2_US onto an NA5_US device).

What is your specific LG phone model and the firmware version you are trying to flash? I can help you find the exact file match.

The LG UP error 0x5319 typically indicates that the firmware you are trying to flash is not compatible with the specific device model or region code. This is often described as "not allowed to change the device" (e.g., trying to flash a different regional variant onto a US device). Potential Fixes

Verify Firmware via IMEI: To ensure you have the correct KDZ file, enter your device's IMEI on an LG firmware lookup site like LG-ROMs to download the exact matching firmware.

Use "Partition DL" Mode: If you are intentionally attempting to "cross-flash" (change your device's regional software), some users find success using the Partition DL option in LG UP instead of "Refurbish" or "Upgrade".

Try Patched LG UP: Standard versions of LG UP often block cross-flashing. You may need a patched or developer version of the LG UP tool (such as version 1.16 or 1.17) that removes these regional restrictions.

Common DLL Fix: Ensure the correct common.dll for your specific model is in the LG UP installation folder to help the tool recognize the device correctly.

Warning: Cross-flashing can cause issues with mobile data or lead to permanent bricking if the wrong partitions are modified. Always back up your data before proceeding. Check KDZ ARB using LG Firmware Extractor or

Are you attempting to change the region of your phone, or are you just trying to unbrick it?

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)

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:

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

No public method exists to downgrade ARB on post-2018 LG phones without JTAG or engineering tools. If you are stuck on a high ARB with no newer KDZ (rare, but happens for discontinued models), you cannot flash any KDZ anymore.
