Device Firmware Update (DFU) Restore
Device Firmware Update allows you to perform a restore when all other attempts to restore the
device fail.
DFU is only necessary if:
• the device won’t turn on
• the device won’t go into recovery mode
• the device won’t charge
To perform a Device Firmware Update follow the step below:
Timing is critical--use a watch to time the steps below!
1. Charge the iPad for at least 5 minutes, then connect to iTunes. If the device is not detected,
open iTunes and move to step 2.
2. Power o the device. Wait 5 seconds. If device will not power on/o, move to step 3.
3. Press Home + Power (Sleep/Wake) buttons together and hold down for 8 seconds and
then release the sleep/wake button.
4. Continue to press the Home button until you see the “Recovery Mode” message in iTunes,
which may take up to 30 seconds.
Note: In DFU Mode the device’s screen is blank.
If you did not get the “Recovery Mode” message in iTunes or the device’s screen is not blank/
black, repeat all steps paying careful attention to your timing.
