FAQ
The flash device should not just be on the same wifi subnet from the PC, but if the PC is connected via a router, then it should be accessible from the PC to the flash device (checked by ping).

If you encounter this errorLibrary not loaded: /usr/local/lib/libirecovery.2.dylib Referenced from: / Users / "username" / Desktop / odysseusOTA / macos /./ idevicerestore Reason: image not found then you need to open the terminal again (from scratch) and enter the following commands:
sudo chown -R `whoami` / usr / local (can ask for a user password)

Next, install Homebrew by running this command:
curl -L github.com/mxcl/homebrew/tarball/master | tar xz --strip 1 -C / usr / local

Now most important, enter this command:
brew install libpng (if the terminal gives an error, then type brew install libpng --universal)

After the done actions, you can read the process of downgrade again.

After a rollback to 6.1.3 4S suspiciously began to eat the loot, I looked detail ...
1-2 times a day, the phone sends sms to number 447 786 205 094 value of each 5 rubles.
It attempts to activate FaceTime without success, I had to turn it off. 200 rubles ate creature.
Somebody something similar in their watches?

Watching the same storage problem is not activated fatetime and iMessage. I thought the problem Jail when for the first time rolled, it was not so after the 2nd attempt. The benefit of SMS Unlimited, YOTA operator. If you decide to accomplish your goal tries.

* demonty,
Not sure whether it affects the activation, but FaceTime does not work on 6.1.3.
