"Ipad Is supervised" Error when loading ITunes, and -38 Error when opening iBackupbot

[Robbonabbo]

Tried to remove the MDM on my ipad but I had two problems:
1 - Once I plugged the ipad in It didnt give me any "Trust Device" box, just started charging.

2 - I noticed it showed me the Ipad in my PC Files as (Ipad) with 60Gb of space

3 - Downloaded ITunes I tried opening it and it gave me An Error Saying "This Device is supervised by another PC, and cannot be viewed on this one"

4 - Tried Opening up IBackupBot, and it kept saying "Error -38" even tho i removed my passcode and Touch ID.

I'm stuck, I think my school got extra secure when doing this. Cannot even make backups smh.
