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.
Below are six proven solutions, ranging from simple settings changes to patched tools.
| Cause | Description |
|-------|-------------|
| Anti-rollback (ARB) mismatch | The KDZ has a lower anti-rollback version than what the phone’s firmware expects. LG increments ARB counters in abl, xbl, and tz partitions. Once incremented, you cannot flash an older KDZ with a lower ARB index. |
| Cross-model firmware | Flashing firmware meant for a different LG model (e.g., G8 on V50) will trigger signature mismatch. |
| Corrupted or modified KDZ | A manually repacked KDZ, or one downloaded from an untrusted source with broken cryptographic signatures, will fail verification. |
| Bootloader locked state | On locked bootloaders, LG UP requires official LG-signed KDZ. If you try to flash a custom KDZ or one with altered partitions, 0x5319 occurs. |
| Partition DL with mismatched partition table | Selecting the wrong partitions in Partition DL mode (e.g., omitting critical ones like abl, xbl) can break signature verification for the rest. |
| USB or LGE Mobile Driver issues (rare) | In very rare cases, driver corruption can cause the phone to incorrectly report authentication status, but this is not the primary cause. |
If you are using LG Bridge to update your phone and see 0x5319:
LG update servers require a direct connection. Security software often flags large incoming data files as suspicious.
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.
If a different official KDZ works, the original KDZ is incompatible.
If none of the above solutions work, it's possible that the issue is device-specific or requires professional assistance. Contact LG support or visit an authorized LG service center for further assistance.

The LG UP error a specific technical failure that occurs when the
firmware flashing tool detects a mismatch between the target firmware (KDZ file) and the device's original regional or carrier configuration
Below is a structured analysis of the error, its causes, and established methods for resolution. Technical Analysis of Error 0x5319 1. Error Definition The error code typically carries the message: "not allow to change the device"
. It serves as a security check within the LG UP utility to prevent unauthorized region-switching (cross-flashing) or carrier modification. 2. Primary Causes Regional Mismatch:
Attempting to flash firmware from one region (e.g., North America NA2_US) to a device originally built for another (e.g., NA5_US). Carrier Locking:
The flashing tool identifies that the device is carrier-branded and refuses to accept "Open" or "Unlocked" firmware that does not match the device's internal ID. Incorrect KDZ File:
The firmware file selected is not explicitly designed for the specific model and variant (IMEI-linked) of the device. 3. Resolution Strategies Description IMEI Verification Use an official firmware lookup tool (such as
) by entering the device's IMEI to ensure the downloaded KDZ matches the device's specific model and regional origin. Patched LG UP Version
Standard versions of LG UP often block these changes. Users often require a patched (Dev)
version of LG UP (such as v1.16 Patched) which bypasses certain region checks. Partition DL Mode
Instead of using the "Refurbish" or "Upgrade" options, selecting the "Partition DL"
mode within LG UP can sometimes allow for cross-flashing by letting the user select specific partitions to overwrite, though this carries higher risk of bricking. Best Practices for Flashing Battery Level: Ensure the device has at least 80% battery power
before attempting any firmware update to prevent mid-process shutdowns. Connection Stability: USB 2.0 port
and the original USB cable. Newer USB 3.0/3.1 ports can sometimes cause communication instabilities during the flashing process. Driver Check: Verify that the latest LG Mobile Drivers
are installed on the PC so that LG UP correctly recognizes the device in "Download Mode". Advanced users can trick LG UP into skipping
