I need it if you still have it
Basically all I can do is list the tools I used and the resources I followed. There is no "app" - it's a process. But I did it in an afternoon and I had zero idea what I was doing before I started. The whole process works like this:
You need another computer, preferably a Mac, and a usb to iPad cable (Lightning) and an open source program called checkra1n.
First a brief overview so you have some idea of the workflow:
1) Install checkra1n on the Mac
2) From the Mac, Checkra1n will install the iOS checkra1n on the iPad via the cable
now move to the iPad
3) On the iPad Checkra1n will install Cydia on the iPad
4) On the iPad Cydia will install a SSH (basically a secure login) on the iPad
stick with me here. It sounds much worse than it is. I had NEVER done this before.
5) Back to the Mac (and the cable) open terminal and following the directions in the SSH (on your iPad) log into your iPad as root from your Mac. Got that? Terminal is open on the Mac, Cydia is open on the iPad. You are reading what to do from the iPad.
6) Using Terminal on the Mac, find the MDM preferences folder and simply delete any and all MDM preferences - normally an iPad has none.
OK, specifics:
read both of these how to's first:

Don't jump ahead, just see how they describe the same process. Each allows for different issues so worth your time.
Checkra1n is found here:
0.12.4 beta · checkra1n
Checkra1n is
not a paid app. It
will not ask for money. It
is not a demo. It will install Cydia on your iPad and Cydia gets you the SSH and other cool features. Both are open source for people who need help like us.
(IF for some reason you download anything but the latest version [0.12.4], poke around. The mismatched link seems to have been corrected but doesn't hurt to double check.)
OK, follow all the directions. Backup you iPad. Move slowly. It all works. Sometimes you have to run Checkra1n twice on the iPad to take. Sometimes you have to reboot to make it work. But it will install Cydia. Once that happens the rest is assured...but tricky. Here is the last bit:
OK, so you got checkra1n and Cydia on your iPad. AND you've installed the SSH from the Cydia menu. Now you're back on your Mac and using the lightning cable, you have logged into your iPad as root. Great. But where to go? OK, google Linux commands to change directories, list contents etc. Not a big deal. But here is where the directory you want is and here is also the command you need to delete the MDM (preference) files:
Location either is exactly or similar to: "
cd /private/var/containers/Shared/SystemGroup/" (you can cut and paste that into terminal). If it's wrong look around using the Linux commands - I had to.
But once you are in the "...
/SystemGroup/" folder do this:
Cut and paste "
rm -rf systemgroup.com.apple.configurationprofiles/" into terminal and hit enter. Those are the MDM preferences and that will "rm" remove them. This is why already having your iPad backed up is a good idea. Now there are no 'necessary' or 'good' "
systemgroup.com.apple.configurationprofiles" so clearing the lot out hurts nothing. It just means your iPad is free of restrictions. If this is successful, reboot and you are done!
I would read all the jailbreak steps a few times before beginning. I would also familiarize myself with navigation in Linux if you have never done this. Both take minutes. Lastly things may be different between your iPad and mine. So just allow for some variation. But this worked and my iPad was utterly unlocked and I was able to install apps, sync it to my Apple account and edit and rearrange my desktop - all things locked for me before removing the MDM.
Message back and tell me how it went!
