If you are not as lucky as to have backed up your iOS device, and now all your data is inaccessible, there is still some hope left as there are solutions you could resort to and that might spare you considerable trouble.
One example in this regard is Erelive Data Recovery for iOS, which guarantees that all your contacts, messages, photos, and whatnot can be retrieved in the blink of an eye.
First off, it need be mentioned that the program can salvage data not only if you connect your iPhone, iPad, or iPod to your PC using a USB cable, but also if you extract your files from an iTunes backup.
As such, the first step you need to take is to decide on the method you want to use, then let the application scan your device or backup and prompt you with all the recoverable files. It is important to mention that they include photos, videos, messages, attachments, contacts, call history, notes, and WhatsApp data.
All your files are grouped into relevant categories, and an option to preview them is provided so that you only salvage data that is still useful to you.
As for how the recovery process is carried out, it should be pointed out that multiple files can be restored simultaneously, and for that, you only need to check the ones you are interested in.
All in all, Erelive Data Recovery for iOS is a tool you could trust in case your iPhone, iPad, or iPod has been affected by issues that rendered your files inaccessible, with the program being able to preview and restore them quickly and without the need to turn to intricate procedures. The app ran without hiccups during our tests, and its GUI seemed to us pretty user-friendly, so it is worth a shot.
