I'm new at this, and unsure what happened. I've got an iPad in PreStage but did not show up as managed. When I search my inventory is it definitely not there. And my device count is off by 1, so I know its not there by this as well. It was purchased with DEP program.
And performing a reset on the iPad (General - Reset - Reset All Settings) did not do anything.
Does anyone have any ideas on how I can get this iPad under management?
Probably best off putting the iPad in DFU mode. To do this, plug the iPad into a computer. Turn the device off. Turn it back on but as you do this, hold the home button at the same time. After a few seconds the iPad should show a connect to iTunes message. You can then use Apple Configurator 2 to restore IOS onto the device.
Thanks for all the advice. Here is ultimately what I did:
1. Turn off the iPad
2. Plugged into a PC with iTunes.
3. Responded to prompt to update the iPad
This returned the device back to the Setup Assistant, which then lead to it becoming managed in Jamf again. Can't believe how easy it ended up being! Thanks again for all the support!
I realize this is an older thread but thought I'd throw my two cents in. I also had this problem after adding another 60 licenses to the school (we ran out of licenses). They refused to connect. I had to refresh the PublicKey (in JAMF Pro) and the Server Token (in Apples School Manager) before the devices would join JAMF Pro correctly. Then I was able to Reset the iPads (erase all content and settings) and they are joining correctly now and able to be managed.
