Part 1: Understanding the Lock – SIM vs. Firmware Lock
Before typing commands, identify what type of "lock" you have.
- SIM Network Lock (NCK): The router asks for an "Unlock Code" (NCK code) when you insert a non-approved SIM. This is a software lock from the carrier.
- Firmware Lock (Branding): Even if unlocked, carrier firmware might hide settings like Band Selection, DHCP, or VPN Passthrough. This requires a firmware update.
- Bootloader/TELNET Lock: Older Huawei devices allowed easy modification via TELNET. Newer B311s-220 units (firmware version > 10.0.x.x) have this disabled.
Goal: Remove the SIM lock first, then flash generic firmware.
