I ran mad when trying my 32GB iPad Mini Retina cellular. I always ended in a reboot loop.
Now I succeeded.
How I did it:
1. restored the device from DFU mode
2. ran Evasi0n just as mentioned above, but:
3. After the first reboot, when the evasi0n app is visible, I disabled auto lock.
4. After tapping evasi0n app the device restarted, for a few seconds there is a slide to unlock bar visible. I slided it and it rebooted without loop.
Very happy after!
Happy new year!
