| Cause | Description | |-------|-------------| | | 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. |
