iOS 11 is announced to be an interesting system but without giving us back. At least that's what I concluded after I tested iOS 11 Public Beta for iPhone and iPad. Currently tested on a iPad Mini 4, iOS 11 did not impress us at all. Has many times when the system remains stuck in menus, there is no possibility of Close all open applications simultaneously, and in addition, they often do not go closed one by one. It is probably the most installed iOS in beta version, ever launched by Apple.
However, we have no concern. It is a system in the stage of tests and development, and the users who have installed iOS 11 beta, I can always pass the last stable version of iOS, version 10.3.2 at this time. We hope that in a few days we will receive version 10.3.3 who passed Beta 7 at this time.
How can we do Downgrade from iOS 11 to iOS 10.3.2 / iOS 10.3.3 – Installation iOS 10.3.2 on iPhone and iPad
First of all let's make sure we have a handy Windows PC or Mac with a newest version of iTunes installed and o Internet connection.
1. Discall IPSW file which contains the iOS, iPad or iPod Touch operating system. Let's be very careful to download exactly the appropriate file for our device.

2. We disable the service “Find My iPhone” or “Find My iPod“. To do this, we go in “Settings” > open Apple ID (pressing on the first option in the menu) > iCloud > slide to stop green the button next to the option “Find My iPhone“. Disabling this option requires ICLOUD PAROLA / Apple ID. Enter the password and “Turn Off“.
3. Connect the device to Windows PC or Mac, open iTunes and activateDFU Mode. Device Firmware Update Mode.
How we put in DFU (device firmware update) an iPhone or iPad
DFU Mode can be activated for devices iPad and iPhone (up to the iPhone 6s) by pressing and keeping the power and home buttons for 10 seconds. After 10 seconds we let the Power button and keep the Home button, until iTunes will defend us that the device is in DFU Mode.
For iPhone 7 and iPhone 7 Plus devices that do not have a physical home button, it is replaced with Volume Down. The button that reduces the volume of sound. The process is the same, only instead of Power and Home, keep Power and volume Down.
4. On the macos we hold pressedOption+Command (or other/option) and Click on the Restore button also iTunes. “Restore iPad…” in the image above.
Windows PC users will hold the key “Shift” while clicking on Restore.
5. We select from the fileIPSW for our device. The one downloaded in step 1.
6. ClickRestore and Update And we follow the steps indicated by the process in iTunes. It will take a few minutes the process of installation.
At the end of the renovation process, the device will have installed iOS 10.3.2.
If before iOS 11 you had a beta version of iOS 10.3.3 and you want to return to it, go on https://ipsw.me and download the fileIPSWwith 10.3.3 for your device
iOS 11 will be available for the general public, starting in the autumn of this year (2017).
And if it is no longer signed by Apple?
Is it a method?
If it is no longer signed, there are not much chance. I don't know if a jailbreak helps you with something. :)
