Can't install CAS on non-CAS CX

I may have corrupted something because when I try to follow viewtopic.php?f=57&t=18920, I reset and ControlX does not show like it is supposed to.
I've previously had CAS working on this calculator but I wanted to update all the programs and such
OS 4.5.0.1180
Boot1 Code Version: 3.0.0.99
Boot2 Code Version: 4.4.0.8
Here is what shows in BtMg

How can I install CAS on my non-CAS calculator?
EDIT**
NVM, it randomly started working again after like 3 tries.
What is the best version should I go on?
