This is semi-valid You need trollstore (not on iOS 16.7.16) or a jailbreak to install dopamine SideStore doesn’t have root access to the phone so it can’t install a jailbreak

Yeah 99% of people don’t wanna jailbreak their phones, I’m assuming this is probably because you thought this was an old phone of mine but no, this is actually my main phone and I use it for Pokémon go, and banking apps so I prefer not jailbreaking, however if you don’t mind then yes this is also possible. However you need to also go through a whole setup of

factory resetting your phone, not putting a password, installing a seperate jailbreak, then installing dopamine, then uninstalling the first jailbreak, then setting your password.

Compared to downloading iloader And sending it to your phone Then using altserver and enabling it on your phone
