iOS :What is the difference between DFU mode and Recovery mode

iPhone and iPad users who troubleshoot their devices themselves often come across terms like DFU mode or Recovery mode and wonder what is the difference between the two and which one should they use.

While both of these modes serve similar purposes they are also fundamentally different from each other and they are useful in different situations…

Recovery mode loads the iBoot Bootloader. iBoot Bootloader’s purpose is to make sure the iOS version the user is installing or restoring on device is equal to or greater than the one already installed. If you try to install iOS 14.0 on a device running iOS 14.1, iBoot will not allow the restore process to move forward…

On the other hand DFU Mode iPhone or iPad’s iBoot bootloader is not loaded. Since iBoot is not loaded in DFU mode, users can use the DFU mode to install an older version of iOS than the one that is installed on their device already…
