On Monday, Apple released a second updated version of iOS 9.3 to address remaining issues that some older iPads and iPhones had with authentication problems that could, in some cases, cause the device to become inoperative, also known as "bricked." The new build, 13E5237, is one number higher than the previous fix. Users who have been unable to move past a stuck Activation Lock screen may now be able to restore the device by attaching it to iTunes on a Mac and upgrading to the new release.
