I found out that rild (the Radio Interface Layer Daemon) controls Android communicating with the SIM,
which has it's own minimalistic OS that's normally vendor-specific which controls the network lock.

Using the daemon would let me possibly bruteforce the unlock code. I'll keep posting my progress here as I go!
