This is because of the latest version of itunes. TaiG doesn’t recognize the latest iTunes library. So the Taig jailbreak errors the main issue was iTunes. Since iTunes 12.1 has broken restores to iOS 8.1.2 and for some user’s, TaiG fails to detect it,This article will guide you on how to downgrade itunes 12.1 / 12.x.x back to iTunes 12.0.1.
Fix Taig Jailbreak error / Downgrade iTunes:
Uninstall Apple Application Support, Apple Mobile Device Support, iCloud and iTunes 12.1.
Rename iTunes Library.itl to iTunes Library.bak. This file is located in C:Users[your username]MusiciTunes on Windows. On a Mac, it’s located in ~/Music/iTunes.
Reboot the computer.
You can Download the Apple iTunes v12.0.1 from here – Windows 32-bit – Windows 64-bit – OS X.
Now Install iTunes
Again, On Windows:
Go to Control Panel and uninstall Itunes.
Even when you uninstall Itunes, Apple still leaves behind old files that need to be uninstalled too. Go and run Microsoft Troubleshooter at http://support.microsoft.com/kb/290301/. Let it run and select the problem as being unable to install software. It will show a list of programs, select iTunes. The Troubleshooter will do all the work for you.
Now run the old Itunes software you got from step 1 and install.
When the old Itunes first runs, you will get an error reading “Library.itl can’t be read”. To fix this, go to the local music folder on your computer. For example on my system it’s located in C:UsersYourUSERNAMEMusiciTunes. From there delete the Library.itl file and then launch iTunes again and it should work as it will create its own version of the Library.itl file.
