How difficult was it to access the watch firmware using Opus? It is absurd to me that it's even possible to do that, but the impact depends on how trivial it is to accomplish.

My agent wasn't cooperative at first so I switched to an account with cyber permission and told it (honestly) that I own the watch and I wanted to rid it of spyware, so it agreed to figure out how the android app did firmware updates. Then it analyzed a copy of the firmware on the Internet to figure out the hardware. Then we modified the stock firmware so it would dump the full contents of memory to an emmc if I trigger a key combination. With all of that it was able to write a detailed spec. Then I handed that off to my regular account and it happily iterated on building a new firmware from scratch.

Kind of surprised the smartwatch company didn't require signed firmware updates. Guessing that won't last very long. Which is ironic because I would happily keep buying their watches if I could continue flashing my own firmware.
