Red screen ti nspire cx non-cas

I bought a nspire non-cas.

But the online seller installed controlx and ndless to make my non-cas to cas.

After I deleted my OS, everytime when I boot my nspire, the Red Screen comes out.

I tried
1. ee+etc and press reset to make factory reset.
2. install the newest os with student software from ti official site.

Need some help. Thanks

What do you mean by a red screen ?
Could you share a picture ?

I never got such a red screen.

When do you get it ? (I mean, what's shown on the screen before it)

Do you mean your current OS version is 4.5.2 ? Is it the CAS OS or non-CAS OS ?

Thanks.
