Key Features of dr.fone - System Repair (iOS)
This is a handy feature which allows you to restore iPad from IPSW without losing any of the data that you have stored in your device. In the past, flashing your device meant losing all your photos, contact and custom data, but that is no longer the case. This feature will restore your iPad to its factory settings, meaning that all unlocked features will be locked; if your iPad had been jailbroken, you will have to jailbreak it again after the restoration is complete. However, you will retain all your custom data and continue using the device as you did before the operating system was corrupted.
It is quite normal for you to forget your passwords and end up disabling your iPad when you use the wrong ones. Getting it to work once more is simple when you use dr.fone - System Repair (iOS). With the IPSW files stored in iTunes, you can now restore the iPad without losing any of the data that you had stored in the device. Regularly backing up your data on iTunes or iCloud is therefore very important if you ever have to restore iPad devices from IPSW files.
