September 25 News, Apple Wednesday magically released the iOS8.0.1 system Update, and only after one hours, the company quickly removed the update file. Although it is only a short one hours, there are still a large number of users in the first time to complete the system update. Unfortunately, if you happen to be using a new generation of IPhone6 or iphone 6 Plus, you are now likely to experience a "mobile phone brick" problem. The specific performance is: After the iphone completes the upgrade and restarts, cannot find the cellular network signal at the same time, TouchID fingerprint verification function completely invalid.
The affected models are currently known to be the iphone 6, iphone 6 Plus, and all older models, such as the iphone 4S, iphone 5 and iphone 5s, are unaffected.
1, download the iOS 8 system image files, pay attention to their model. Website downloads require a developer account.
IPhone 6 Plus (a1522/a1524):

IPhone 6 (a1549/a1586):

2, close the iphone Find My iphone features, specific location: Set-> iCloud-> found my iphone.
3. After downloading the IPSW image file, connect the iphone to the computer and open itunes.
4. Hold down the SHIFT key and click "Check for Updates".
5. itunes opens a File selection dialog box to select the IPSW file you just downloaded.
6, determine to continue the update operation.
Note: This is an update upgrade, not a restore, so there is no need to back up any data (of course, just in case you can back it up), after the completion of the iphone settings, files, data will not be lost. In other words, we are demoted to iOS 8 through the "Upgrade" approach.
7. The iphone will be prompted to reboot and will be restored to iOS 8.0 upon completion. Everything is done.
