The Difference Between Recovery Mode and DFU Mode
The Main difference between the Recovery mode and DFU mode is iBoot. Recovery mode uses iBoot during restoring or upgrading your iPhone while DFU mode bypasses the iBoot so you can downgrade the current firmware because there is no iBoot agent during the DFU mode. About iBoot, iBoot is the bootloader on iPhone OS devices. iBoot acts on restore while iPhone is in Recovery Mode, iBoot makes sure that you are flashing a firmware version greater than or equal to a current one. If you are not, iBoot will not allow the restore to proceed. Because of this, firmware downgrading must be done in DFU mode.This means if you need to restore your iPhone to current version simply put the iPhone in recovery mode and iTunes takes care of the rest but if you need to downgrade your current firmware to lower one you need to put your iPhone in DFU mode. For example you can’t downgrade Firmware 3.0 to Firmware 2.2.1 without entering in to DFU Mode.
Recovery Mode : Recovery Mode is a state of iBoot that is used during standard upgrades and restores. As iBoot is active, it does not allow you to downgrade your device’s software. Also, unless it is ‘pwned,’ it will not allow custom firmware to be flashed.
