5. Universal SIM Unlock
While this firmware does not technically unlock a network-locked IMEI, it removes the software restrictions that prevent a router from accepting a non-carrier SIM. For hardware-locked devices, you still need an unlock code, but for SIM-lock via firmware, the Universal version bypasses it.
Step 1: Download the Correct File
Search for Huawei_B312-926_Update_10.0.3.1_h192sp9c00_Universal.bin from a reputable Huawei firmware archive (e.g., huaweifirmware.com or 4pda). Ensure the file size is approximately 25–30 MB.
1. Unlocking Carrier Aggregation (CA) Combinations
Older carrier-locked firmware often restricts which 4G bands can be combined for speed. The Universal firmware enables wider CA combos (e.g., B7+B3, B28+B7), potentially doubling your internet speed if your tower supports it. Turn off the router
Step 2: Prepare the Router
- Turn off the router.
- Remove your SIM card (optional but recommended to prevent network interruptions).
- Insert an Ethernet cable from your PC LAN port to the router’s LAN port.
- Set your PC’s IP to automatic (DHCP).
