The last OS I installed was 4.4, so should I send a 4.0.3 boot2 and then flash OS 4.0.3, or a 4.4 boot2 and then reinstall OS 4.4?
Aditionally, what TTL voltage level does it expect? 3.3 or 5V?

TTL is 3.3V.
Right after I can install any OS version that's the same or above the flashed boot2 correct?
Also, when I finish the process, must I do anything to remove any reminiscent components of controlx/nloader (diags) or is it already removed?
Is there a way to reset the calculator to its exact factory state, so I can mod it again with the reccomended instructions, since I remember using nspartmagic and BtMg?

Re: Red screen updating CX CAS to 4.5
I just managed to recover the calculator by flashing boot2 4.4.0.8 and flashing os 4.5.4.48, by way of soldering wires to TX, RX and GND and using the FT232 with extraputty.
Now, can I just proceed to install controlx + nboot for CAS, or must I first remove something relating to nLoader or any previous OS (like a full factory reset)?
Thanks for all the help so far
