3uTools has supported the download & flash of both iOS9.3 Beta4 and new iOS9.2.1.
The latest update for iOS9.3 beta can fix the “1 January 1970” date bug which makes 64-bit
iOS devices become “bricks”.
Now the particular iOS9.2.1 can restore the “Error 53”, a software issue that rendered useless iPhones that had had their home buttons replaced by third parties.
3uTools can update the firmware database as soon as the Apple releases the iOS beta version and final version.
Connect your iOS device to 3utools, and then you can easily find the iOS ipsw versions which are
compatible with their iOS devices, and choose to download them with a rapid speed.
3uTools Easy Flash can restore your iPhone, iPad and iPod Touch to the beta version without an Apple
developer account.
In addition, you can use the button of “Don’t erase user’s data ” to keep the phone data during the
flashing process.That means it’s not required to backup your phone data automatically before flash.
However, please don’t use this button if you want to downgrade your device!
As to the final version of iOS 9.3, it’s supposed to come out in next month so that iPhone 5SE,
Apple’s new 4-inch handset, can run it. .
