Hi, I am replacing a battery in an iPhone 6s because the original one won’t hold a charge for more than a minute. So I bought a new battery, and it only boot loops. Supposedly the battery is brand new so I don’t know if that matters. But I tried to restore it and reinstall the iOS but it will not connect to the computer at all. iTunes is up to date, and I tried the cable with my other phone and it works with that one
Sorry, your phone is unsupportable now that it's been tampered with.
iPhones are not considered user serviceable.
Apple does not sell iPhone parts, including batteries to anyone other than authorized service providers. You can't buy one to install yourself.
That means we can't help you and Apple won't touch it.
By physically opening it up and replacing or attempting to replace parts, you have forfeited all rights to service or support on that device.
Now maybe you understand why they are not considered user serviceable.
Find a 3rd party shop and see if they can help you or recycle it and buy a new phone.
So what does that mean unsupportable
IPhone 6s boot loop after battery replacement, won’t connect to itunes
