So I just guide you how to restore your iPhone. Good luck.
Note: This is a 3rd party application, so when you manipulate the considerations carefully. During the restore process you are not unplugged, do not turn off 3uTools. Also, you need to leave your iCloud account before doing so to avoid undesirable conditions.
If you don't have any issues in your iCloud ( like forgetting the password of your iCloud )then it's safer to use iTunes when every time you want to restore your iPhone to avoid any errors. But if the is your iPhone is not unlock then maybe consider using 3utools for jail breaking.
Hi HelenR.. although i have not yet used the 3uTools i'm pretty much aware of its capabilities. I'm a techy guy so i always keep my self updated on applications and reviews. From what I've read about it, this application is a multi tool application for IOS. There's a bunch of them actually but 3uTools is more renowned due to its user friendly interface. 3uTools offer's jailbreaking and flashing function with other tools for maintenance and video file conversion.
Just like any other tool using applications like this takes some practice and skills..that's why a user friendly interface is a plus. Also they have a website which have some several tutorials to help users. You can check their website here : http://www.3u.com/tutorial
Although i'm not in a hurry to use this app...specially on my phone . I would love to test it's capabilities.
Now can this app restore a phone? Probably yes.... but it all depends on the problem of the phone. If it is software, firmware, related yes it could. Bit if its a Hardware problem, mostly not. Software and hardware issues on any phone have different factors. Although they are co-related, trouble shooting and repairing for both software and hardware issues has different approach.
