iPhone 6s+ Won’t Update to iOS15

Hello! I recently bought a used iPhone and am struggling to sync it with my old phone. Long story short, I figured out I need to update the phone to the newest software- currently, it’s running iOS13.3.1. When I try to install iOS15, it’ll start as normal (but very slowly) and then, several hours later, it reaches the end of the loading bar and again offers to “download and install”. Sometimes I’ll also get an error message that say *“Software Update Failed, failed to install iOS 15.0.1”. -_-

Here’s what I’ve tried so far:

resetting the phone
restarting the phone
resetting network settings
using a different wifi connection
restoring from iTunes backup (my computer is too old to get the newest iTunes so it’s not able to download iOS15
leaving it overnight with auto updates on

Anyone know what I’m missing here?

Just in case the new phone is jail broken do this

Recovery mode or DFU https://support.apple.com/en-gb/HT201263

If you finish up with being asked for a strange Apple ID and password then it was indeed jailbroken and now useless to you without the original owner.
