Upgrading the System Using a USB Flash Drive

Upgrading the System Using a USB Flash Drive


Hardware environment

The hardware environment required for the upgrade is as follows:

  • USB port: The AR161, AR161W, AR161EW, AR161EW-M1 routers provide USB 2.0 ports.
  • USB flash drive:
    • Ensure that the USB flash drive is compatible with the router. Huawei-certified USB flash drives are recommended. The following USB flash drives have passed Huawei certification:
      • Netac: U208 (4 GB), U208S (16 GB)
      • Kingston: DT108, DT101 (8 GB), DTSE9 (8 GB, 16 GB)
      • SanDisk: CZ50 (8 GB, 16 GB), CZ36 (8 GB, 16 GB), CZ43 (16 GB)
      • HP: V250W (8 GB, 16 GB)
      • TOSHIBA: UHYBS-016GH/008GH
      • PNY: HOOK Gold Edition (16 GB, 32 GB)
    • The USB flash drive must use the FAT32 format; otherwise, set the format to FAT32 before using the USB flash drive.
    • The available space of the USB flash drive must be larger than the total size of files to be loaded.

Files to be loaded

Files to be loaded include:

  • indicates the target upgrade file, with the file name extension .zip.
  • unlmt.cfg: indicates the unlimited upgrade in the period when the USB flash drive is installed.
  • once.cfg: indicates the one-time upgrade. That is, the system is upgraded only for once in the period when the USB flash drive is installed. This file is recommended for the system upgrade.

To download, visit and log in using a registered user account. If you have no user account, click Register to apply for an account first. Choose Software > Product Software > Enterprise Networking > Router > Access Router. Download the system software matching the router.

The files once.cfg and unlmt.cfg are empty and used for the one-time upgrade and unlimited upgrade respectively. They are mutually exclusive.

Copy files

Create the dload folder in the root directory of the USB flash drive, and copy the files and once.cfg, or and unlmt.cfg to the dload folder.

  • Do not power off the router when the router is copying files. Otherwise, the upgrade fails or the router cannot start.
  • Do not remove the USB flash drive before the upgrade is complete. Otherwise, data in the USB flash drive may be damaged.


Install the USB flash drive and start the upgrade.

  • One-time upgrade: After the USB flash drive is installed, the router checks whether the sizes of the files in use and in the USB flash drive are the same. If not, the router performs the upgrade. When the upgrade succeeds, the router automatically restarts and runs the upgrade file. In this case, the files in use and in the flash drive have the same size. The router does not perform an upgrade if restarted.

  • Unlimited upgrade: After the USB flash drive is installed, the router automatically restarts and performs the upgrade without comparing the sizes of the files in use and in the USB flash drive. When the upgrade succeeds, the upgrade success message is displayed on the screen connected to the router. The router does not restart or upgrade. After the USB flash drive is removed, the router restarts. The upgrade is complete.

Verifying the Configuration

In the upgraded Android OS, choose Settings > All Settings > SYSTEM > About AR > Android version and check the version.
