Locked e-waste Cricut Maker restored via USB proxy that rewrites serial number
↗
A discarded Cricut Maker that showed 'Machine deactivated' was returned to full functionality by intercepting USB communication and rewriting its serial number with an RP2040-based proxy.
This demonstrates that Cricut's machine deactivation can be bypassed at the hardware level, allowing e-waste devices to be reused. It also highlights a potential security flaw: serial numbers can be rewritten and registered to other accounts, which could enable abuse. For engineers, it shows a practical method of USB proxying with an RP2040 to intercept and modify device communication.

The Cricut Maker was locked with a 'Machine deactivated' message when connected to the software.
The author used an RP2040 as a USB proxy to rewrite the serial number in USB CDC packets.
