IT Consultant from Germany, Linux enthusiast, BSD fanboy and firmly convinced that Ancient Domains of Mystery is the greatest video game of all time (and always will be). You'll find me here talking about Open Source, self-hosting, advanced networking (proud operator of AS201379), smart home shenanigans, and anything you can torment with a terminal. Cat pictures also welcome. Left, antifascist, vegan. The trifecta your uncle warned you about.

My ThinkPad T14s shipped with an Intel XMM7560 LTE modem locked behind a Lenovo unlock blob. I replaced it with a ~100-line bash script that does the exact same handshake - and explains, in plain shell, what the "unlock" really is: a SHA-256 over a 4-byte constant. No magic, no blob.
Full credit to Floris Stoica-Marcu for the script.
