I have an iPad 3, formerly running jailbroken 7.0.4. Performed a DFU to 7.0.6 and I'm stuck at the point where I'm supposed to enter my Apple ID and password. Not working on the device, though it works as expected to log into icloud.com, and it works fine on my iPhone. I removed the iPad from my devices in iCloud, as I read elsewhere that would clear this condition, but I still can't get past the prompt. Ideas?
