I am restoring my Apple Watch Series 3 through iTunes and want to further develop it through modifications. Yes, I'm aware of the consequences, including the beta released by Apple. Before I bother taking down older generations and updating newer ones on screen, I have been granted self-authorization.
I would like to know which firmware I would use. I've tried the "IPSW me" site, but the zip files contain no iTunes files to choose restore / update. It is another site, but requires the purchase of an ibus1-2 before you can access such files. The port I use is the Yun port, but only intentionally used to install different demo setups.
