Instructions how to convert iPhone to DFU mode, recovery mode, etc.

DFU mode (Device Firmware Update) is a device firmware update mode. It refers to emergency modes and is recognized by iTunes when you connect your iPhone or iPad to your computer using a USB cable as recovery mode.

It differs from the Recovery Mode (Recovery Mode) in that the device does not give visible signs of life in this mode (the control button does not work, there is no image on the display). The Recovery Mode is started using the iOS operating system, and the DFU mode bypassing the operating system, i.e. at the hardware level.

DFU mode is used to restore or update the iPhone firmware (also known as iOS) in cases when iTunes cannot perform the necessary operation using standard tools. In some cases, the DFU mode can fix a system crash in the iPhone, which will allow the device to reboot in normal mode.

It also happens that the iPhone or iPad has failed, and the iOS firmware does not start, in such cases they use the Recovery Mode and DFU modes. To begin with, they always try a softer mode - Recovery Mode, but if it doesn't help, then they already use the DFU mode.
