Need help: My iPhone stuck on install now screen during software update
You can use idevicerestore to attempt a fix when you have an iPhone stuck on install now screen. idevicerestore is a command-line application that communicates directly with Apple's servers to download and restore official iOS firmware to your iPhone . It was developed as part of the libimobiledevice project and has been maintained since 2010 .
If you have an iPhone stuck on install now screen, idevicerestore offers no advantage over using iTunes or Finder on a Mac or PC . Both methods:
1. Require you to put the phone into Recovery Mode using button sequences
2. Download and restore official signed firmware from Apple
3. Can update (preserve data) or erase (factory reset)
The only real difference is that idevicerestore runs on Linux. If you do not have access to a Mac or Windows PC, and you are comfortable with the command line, this is a valid free option. But it will not magically fix the problem without a restore operation.
