This is awesome! I desperately want to replace the stock firmware, an open source alternative would be fantastic. Have you poked around the stock firmware to see how the telemetry is delivered via the modem, out of curiosity? For me that’s the number one thing to stop while building out an open alternative in the meantime.

I know way back in the day before any of the cloud stuff, the free trial system used to raw write to an unused area of the filesystem structure near the beginning of the drive in order to mark down unremovable details about the trial so you couldn’t just free trial over and over and over.

So I wouldn’t put it past them to have a similar fingerprint written somewhere otherwise inaccessible.
