I had a teacher come in today with an iPad that had a passcode on it. The device was not on Wi-Fi so I could not remotely clear the passcode. Is there a way to enable Wi-Fi without being able to access the settings? I tried sliding up for the control center (or whatever it's called) and had no luck. I'll probably have to wipe it but we'd like to access some data on the device first if we can. Thanks.
I would make sure its connected to power and make sure its in range of any wifi network that it is already configured to use. If neither of those work you may be out of luck.
I did wonder if you could plug it into the iTunes library it is synced with but I think that still doesn't work if the device is in a locked state.
I've had this problem as well. I found this video and the solution has worked for us so far :http://9to5mac.com/2014/01/10/video-connect-your-ipad-to-the-internet-via-ethernet-cable-with-this-easy-hack/
It's a hack to hardwire your iPad using an ethernet connection. I've already used to to connect and then unlock 3 iPads with Casper. Kind of a pain to set up, but I just leave it set up in my office so it's ready when I need it.
I know that this is an old post, but if you are managing a lot of the newer iPads, you can use a lightning to RJ45 network adapter. Then you can send your commands from Jamf to reset the passcode. https://www.amazon.com/Lightning-Ethernet-Yvelines-Converter-Connection/dp/B075TYL5J6/ref=sr_1_2_sspa?s=electronics&ie=UTF8&qid=1541512995&sr=1-2-spons&keywords=lightning+to+rj45&psc=1
I hope this helps!
