Today Apple rolled out a minor iOS 8.0.1 update for all the supported devices, including the recently released iPhone 6 and iPhone 6 Plus. However, instead of getting improvements, these devices are plagued with strange problems. The supported devices, especially iPhone 6 and iPhone 6 plus, are showing “NO SERVICE” after the upgrade. Some users are also reporting Touch ID issues after installing iOS 8.0.1.
Apple has also taken the notice of these problems and has pulled the update. If you have updated your device to this iOS firmware and are facing any weird problem, you’ll have to downgrade to previous iOS 8.0 version in order to solve these issues.
Except the downgrade process, till now no other method is available to resolve these problems. The users have already tried different options like resetting the device, resetting the network settings, erasing the phone etc but none of these worked.
How to Downgrade iOS 8.0.1 to iOS 8.0 to Fix “No Service” Issue:
Before you go for actual downgrading process, it is very important that you make a backup of your device first so that you don’t lose your precious data during the procedure. It is always recommended to use the iTunes to perform the backup. Don’t rely on iCloud backup only because it may skip some items you wanted to save.
Install the latest version of iTunes on your PC. Head over to Apple’s iTunes page to get the latest version.
Download iOS 8.0 for your device and save it on your PC. In case it appears as a zipped file on your Windows PC, unzip it using an appropriate software. The final product should have .iPSW extension.
Connect your phone with the PC and launch iTunes.
Select your device from the left-side column in iTunes.
Hold down the option (alt) key on Mac or Shift key on Windows and then click on “Check for Update”.
Navigate to the folder where you saved your downloaded iOs 8.0 iPSW file and select it.
Sit back and let iTunes finish its process. After the installation is complete, simply unlock your iPhone and you should see the signal back on the status bar.
Now your device is running on iOS 8.0. Don’t update to iOS 8.0.1 until Apple releases the new version with the fixes for these issues.
The users who upgraded to iOS 8.0.1 but are not facing any such issues are suggested to keep using the latest version.
Before this procedure, turn off Find my iPhone feature and after the downgrade is complete, turn it on again.
