Member: 817864 Status: Offline Thanks Meter: 1 | please use this like to put it in dfu mode and restore it to factory settings if its factory unlocked or else u have to use a custom firmware to restore to prevent base band update DFU means Device Firmware Update. If a restore using Recovery Mode doesn't work you will want to use DFU Mode as a last resort. When placing your iPhone into DFU Mode it does not load the OS before attempting the restore |

Member: 817864 Status: Offline Thanks Meter: 1 | To put the iPhone into DFU mode so you can do an iTunes firmware restore follow these steps: Step One Open iTunes and connect the iPhone to your Mac. Step Two Press and hold the Home button and the Sleep/Wake button at the same time. Step Three After exactly 10 seconds release the Sleep/Wake button. Continue holding the home button until you iTunes pops up a message telling you that it has detected an iPhone in recovery mode. The iPhone screen will remain black NOTE***: It may take a few attempts to get your iPhone into DFU mode. Generally, I hold down both buttons then release the Home button just before I think the Apple logo would appear. If you are still holding both buttons down and you see the Apple logo you are holding them down for too long |
