Nspire back to CAS?

Hi!/Salut!
I installed the CAS nLoader on my AD revision calculator back a few months ago. I decided to revert back to non-CAS later on because of the upcoming exams requiring non-CAS calculators. However, an error occured during my transition back to non-CAS where BtMg would not read my memory and would not flash. I came for help here in the forum chat, where someone advised me to reset my calculator. I wonder if there is any way to reinstate CAS on my calculator, since I read somewhere about how my current flash is on the Diags partition instead of the main system partition? Thank you, and sorry if I'm not making sense here
My calc is currently updated to 4.5.2.8.
