I have iPad and I recently installed iOS 11 beta 1 on my iPad. Now I see some battery issues and I want to downgrade to iOS 10.3.2. But I checked on the internet and shows that a PC is compulsory. I don’t have a PC.
It's impossible without a PC or a Mac to initiate the wipe and also host the reinstall image download and USB control during the downgrade.
In addition to the "computer" - you need an Apple tool like iTunes (Mac or PC) or Xcode or Apple Configurator (or a third party one like Ground Control) to reload the older OS, since there is no OTA bundle for downgrading.
Need a computer. You can download ipsw file on PC or Mac from https://ipsw.me, and restore iPhone with the ipsw firmware by using iTunes. Or use system recovery tools to install ipsw without iTunes.
By the way, iOS 11 beta is only for the developer, not ready for common users now. iOS 11 beta is less buggy but still has many problems. Be patient and wait.
Actually it is possible to downgrade from iOS 11 to iOS 10 without computer!
Firstly, you need to get the apple configuration profile I think it’s called that? But you need to download the iOS 10 version of it and reboot your iPad and then you’ll to software update and see that iOS 10 is there to be updated and then you will be downgraded!
