Apple today released the final iOS 11 firmware for us. We posted a tutorial Top 5 things jailbreakers must know about iOS 11 earlier, while today if you want to upgrade your iDevice to the latest iOS system, you must know the following matters.

1. Check if your iDevice is compatible with iOS 11
iOS 11 compatible products:
iPHONE - iPhone 8, iPhone 8 Plus, iPhone 7, iPhone 7 Plus, iPhone 6s, iPhone 6s Plus, iPhone 6, iPhone 6 Plus, iPhone SE, iPhone 5s.
iPAD - iPad 12.9‑inch iPad Pro, 10.5‑inch iPad Pro, 9.7‑inch iPad Pro, iPad Air 2, iPad Air, iPad 5th generation, iPad mini 4, iPad mini 3, iPad mini 2, iPod touch 6th generation.

2. Back up your iDevice before upgrading
It is a good habit to back up your iDevice now and then. Just in case. If you upgrade your iDevice to iOS 11 using 3uTools, remember to select the checkbox “Retain User’s Data While Flashing”.

3. Don’t upgrade iDevice at once
The final iOS 11 may have some undiscovered bugs at this moment, so you’re not suggested to upgrade your iDevice immediately. For instance, someone reported that the 3D touch is not smooth any more after upgrading to iOS 11. Just wait, if there is no update then you can upgrade.

4. keep a stable Wi-Fi environment
If you upgrade your iDevice via OTA, make sure you have a stable Wi-Fi environment. But you’re not suggested to upgrade iDevice using OTA because it may cause white apple issue due to the bad network.

It is worth mentioning that you need to customized backup your iDevice before downgrading~ some iOS users reported that they lost iDevice's data after downgrading. In addition, your backups of iOS 11 can't be restored to iOS 10.3.3, that's the reason why you need to customzied backup your iDevice. tutorial|What's Customized Backup & Customized Restore?
