Entering DFU Mode
DFU (Device Firmware Update) mode is required for most manual restores. The button combination varies by device:

Connect device to computer, then follow the on-screen instructions in iTunes/Finder to enter DFU mode.
💡 Tip: In DFU mode the screen stays completely black. If you see the Apple logo or a "Connect to iTunes" screen, you entered Recovery mode instead — try again.
