From the article:

With ChatGPT and a CH341A flash programmer at hand, the intrepid modder went through the following process:

1. The CH341A was used to dump the Panasonic’s BIOS.
2. The dumped bios was uploaded to ChatGPT with instructions to completely disable SecureBoot and its proprietary keys.
3. The GPT-modified BIOS was flashed back to the device.
4. Fingers were crossed… and it worked!
5. OS wrangling ensues, various compatibility wrinkles are being ironed out.

It used to be that someone hacked a device and wrote about everything they read and debugged and passed on that knowledge. Not anymore, just feed instructions to a machine and trust it doesn’t spit something out that won’t kill you if you blindly trust it.
