As for the jailbreak, AFAICT, the update didn't break it. The only thing I can think of that might (I'm a bit rusty on the K3 front ^^) lead to a U006 is if he was using Yifan's JB. The factory reset doesn't wipe/disable his, just mine. So, this Kindle should effectively already/still be jailbroken. As always, check the logs to find the real culprit
