So, I've tried jailbreaking it - didn't work, others tried and failed too. Some of them were lucky and did it. So I made a poll, about it.
I don't know if I should keep trying or give up.
Couldn't get my iPad Air or Mini Original to JB on 7.1 B2
Did you OTA to beta 2? If so, that's probably why. Try restoring to beta 2 and then jailbreak. I did that and mine works fine.
I did exactly that. Restored from the 7.1 B2 ipsw off iTunes. I applied the JB and it would leave me stuck on a endless loop. 7.0.4 works fine.
Edit: iPhone 5 and iPad 3 JBs work fine on 7.1 B2... hmmm
