How do I undo the IOS 11.2.1 update?
My sister updated my software without my permission. And I know that when you do an update it slows down. Not only that but every time I plug my iPhone into my usb on my computer it doesn't recognize it. How the hell do I undo it without my computer?!
Almost impossible by design to rollback an iOS ipdate.
Updates don't slow phones down.
You can't undo an iOS update. Also not all iOS updates slow down devices
You can only downgrade to the lowest signed version of IOS. Anything bellow that is impossible. So the lowest you can go is iOS 11.2 (one just before 11.2.1)
When you install any firmware on an iOS device, it contacts Apple's servers to check if it is allowed to or not. If the firmware is being signed, you will be able to upgrade/downgrade. If it's not being signed then you will just get an error.
You can check for yourself at www.ipsw.me for which versions are being signed. 11.2 is the lowest compatible iOS version you can downgrade to.
To downgrade, simply download the correct IPSW for your device. Plug your phone into iTunes, hold down shift and press restore. Select the IPSW and restore to that version

She said she was with att and it was unlocked. And its an iphone 4. (i'm with att by the way if you need to know)
- Is there anyway to undo the backup restore that itunes does for your Iphone? I got a new iPhone 4s under warranty after my old was damaged. I started fresh and started to input numbers myself as well as apps. I just plugged it into iTunes and now all of my old stuff is back on my new phone. Contacts, pictures, etc. Is there anyway that I can undo the backup restore iTunes did to my phone and go back to how I had it before I plugged it up?

Neither the computer nor iTunes are recognising my phone and I've been working on his for an hour, I want to stop the update so I can go to bed, how can I do that? It's only at the stage where it has a symbol on the screen of the iPhone cable linking to iTunes
