  • Feature enhancements (e.g., band locking, SMS over LAN)
  • Bug fixes (DHCP, Wi-Fi dropouts)

This paper outlines a tested methodology to safely update the firmware on the B311-221.

3. Obtaining the Correct Firmware File

Official channels:

  1. Huawei’s update server (auto-update via Web UI → Device → Update)
  2. Local carrier (some lock firmware; e.g., Vodafone, T-Mobile)
  3. Community archives (e.g., 4pda.to, Huawei-Firmware.com) – use only if official fails

Naming convention example:
B311-221_UPDATE_11.0.2.13(H191SP2C00).bin

Verify SHA-256 checksum if provided.

Option 2: Manual Update via Web Interface (ISP-provided file only)

Only do this if your ISP gave you a firmware file or you are 100% sure it’s correct.

  1. Download the correct firmware for your exact model (B311-221) and ISP variant (e.g., Three UK, T-Mobile).
  2. In the router admin page: Settings → Device → Update → Local update.
  3. Select the .bin file and start update.
  4. Wait 5–10 minutes. Do not unplug.
