Help with rebooting NSPIRE CX

Hello, I am trying to resolve my calculator issues with an older CX (non CAS) model. The problems started when I deleted all my files on accident when trying to speed up the calculator since it had become quite slow. I assume this resulted in ndless being removed. However, when I readded endless 4.4.0 via the tutorials it said that it was already installed. Which I thought was ok. However, now whenever I try to enter anything inside a document number/ symbol/ etc. it reboots. I don't know how to approach solving this. I would appreciate any help. So far I have tried to reset the calculator to default settings however I cannot tell which guide I should use. If I recall correctly I am not using the factory OS since it indicates CAS at the top and this is a non-CAS cx. Thank you once again. If this topic has similarity to another, then please point me in the right direction so that I may resolve it via those instructions.
