Omar kept meticulous notes in a private log: each router’s original firmware, the exact change, which SIMs worked, and which failed. He learned to expect — and respect — the fact that firmware is often a living thing, updated by manufacturers and carriers to address new network policies or security issues. A build that seemed universal on Monday might be partially blocked by Friday. Second, Huawei’s update tools often audited the firmware
