Because you are so far behind with the version of iOS, you may need to use iTunes on a computer to complete the update.
Update your iPhone, iPad, or iPod touch with iTunes - Apple Support (CA)
Update your iPhone, iPad, or iPod touch with the Finder - Apple Support (CA)
I’m not sure what it’s existing is but it is definitely a 6s plus. When I click the install now button it says verifying update and it loads and then says there was an error downloading iOS 15.4. I have a SIM card in it and everything but idk. I have tried it on a few different peoples WiFi and no luck
What happens when you try?
Any error message?
What is the existing version of iOS?
If it's currently running iOS 12.5.5, it is NOT a 6s Plus. It is a 6 Plus.
It’s currently 12.4.1
I can’t update my iPhone 6s Plus to iOS 15.4!
