What is DFU Mode
DFU stands for Device Firmware Update. It reloads the firmware and restores the iPhone to a factory-fresh state. Be careful: it erases all data, so back up first.
How to Enter DFU Mode (Manual)
Connect iPhone to computer
Press and release Volume Up
Press and release Volume Down
Hold Side button until black screen
Keep holding Side + Volume Down for 5 sec
Release Side, keep holding Volume Down until detected
Screen must stay black → you’re in DFU mode
How to Exit DFU Mode (Manual)
Press and release Volume Up
Press and release Volume Down
Hold Side until Apple logo appears
One-Click Solution with UltFone
Enter and exit DFU mode in a single click, no button combos. It also supports iOS repair, backup, and data transfer.

🤨 Understanding Key Terms and Resources
DFU (Device Firmware Update): A state that allows iTunes/Finder or third-party tools to interact directly with iPhone firmware. Unlike Recovery Mode, DFU reloads both firmware and software, making it the deepest type of restore.
Recovery Mode vs DFU Mode: Recovery mode still shows the “connect to computer” screen, while DFU mode keeps the display completely black.
iCloud Activation Lock: DFU restore does not remove iCloud lock; it only restores the device firmware.
