i do this update

Hello faysal56,

From your post we see that your device needs iOS 14.5.1.

For this version, it's compatible with iPhone 6s and later, and iPod touch (7th generation.) iPad Pro (all models), iPad Air 2 and later, iPad 5th generation and later, iPad mini 4 and later, would be able to get iPadOS 14.5.1

If the model for your iOS device is compatible, this will help you complete the update: Update your iPhone, iPad, or iPod touch

We hope this helps!
