Best for: Older models where software resets fail.
If you set up security questions when creating the admin password:
| Issue | Solution | |-------|----------| | USB drive not recognized | Reformat to FAT32, max 32GB size. Use another USB port. | | Portal says “Invalid GUID” | Re-export the file – it may be corrupted. Ensure you uploaded the correct file. | | Reset file not loading | Make sure the file is in the root directory of the USB (not inside a folder). | | DVR still asks for old password after reset | Try rebooting the DVR with the USB inserted. Repeat the import process. | | “Forgot Password” option missing | Your firmware is very old. Try defaults or contact support directly. |
