Thanks.

Then, could you show us a picture of what you get on the screen after installing OS 4.5.0 and holding

before the reboot ?

Unlike with OSes 4.5.1-4.5.2, nLoader isn't supposed to display a red-error-screen with OS 4.5.0.

This time it says "[M7] You cannot install a version of the OS that is older than the currently installed version."
I'm gonna attach the video trying to update this time.
I share the video that I'm trying to install OS again.

Thanks.

So CX OS 4.5.2 is the only version which could work.

Sorry for the late response.
I just tried with 'Ti_NspireCX_4.5.2.8.tco' but still shows the message "Operating System not found. Install OS now".
Would you recommend what I should do now?

Tomorrow, I will receive the USB to TTL connector!

Additionally, I could only see this file 'NspireLogs.zip' when I connect the calculator using a software.
