1. Double-check your phone model

• Boot into Download Mode – the screen should show the exact model (e.g., LM-G850).
• Make sure the KDZ filename matches exactly (e.g., G850N20a_00.dz for LM-G850).

• Wrong LGUP version (older/newer than required)
• Using incorrect DLL package (e.g., using DLL for a different chipset/region)
• Missing or incompatible USB drivers (LGUP driver/ADB driver)
• Phone not in correct mode (Download Mode vs. Normal/ADB)
• Faulty USB cable or port (use of USB hubs)
• Authorization/permission blocking (secure boot, locked BL, region locks)
• Corrupt or incomplete KDZ/UP file or partially extracted firmware files
• Conflicting software (other phone managers, virtualization tools)

8) Check bootloader / hardware locks

• If the bootloader is locked or the device enforces signed firmware (secure boot), LGUP may refuse to flash. Check model-specific unlock steps (OEM unlock, authorized firmware). For carrier-locked/region-locked devices, use matching signed firmware.

6) Use different firmware file or re-extract KDZ/UP file

• Re-download the firmware. If it’s a KDZ, ensure it’s not corrupted. If using a DLL that expects partitioned files, use appropriate package.
• Some community instructions require converting KDZ to TOT or using partitioned images.
