Workaround for TaiG stuck at 20%

There is an issue where the TaiG jailbreak of iOS 8.3 can get stuck at 20%.

If you've waited for a while and/or receive an error -1101, you may have to follow these steps.

To resolve this issue you must install iTunes 12.0.1. I suggest that you cleanly remove the current version of iTunes on your PC. You can do this by following these steps.

Reboot, then download and install iTunes 12.0.1 (64 bit) from Here.
or iTunes 12.0.1 (32 bit) from here.

Once you've installed iTunes 12.0.1 be sure not to update it when prompted, then run TaiG.
I Hope that your problem will be solved.
