I mean that I can't downgrade the OS. So the OS should be installed at least partially, or am I wrong?

Looks to me like the OS gets corrupted on first start.

Hi guys, I am new here.

Just wondering about this.
After Upgrading to CX CAS from CX NON CAS.
How to completely resert everything back to normal? I have 4.4 version AB hardware.

Btw, if you upgrade your calc from non cas to cas does the product id change aswell?
Or is it the same product ID regardless which OS you are running?

Thanks

The product ID changes, but that's actually a bug; ideally it would stay the same. It will in the next version, which has an ETA of, uh, whenever I'm not busy with college.

Ok, so thats a bummer

I have some apps and if my ID changes chances are that the apps wont work.

From which step to follow to reset the calc back to default 4.4.0 NON CAS OS version without that warning at boot?

Step D, except with NONCAS_OS file

Can you PM me a link to the apps? I can try to see if I could patch them to work anyway. If I do, please don't post them anywhere (it's piracy)

It could be fixed easily by resuming at step D and being more careful.

But you need an OS for this, and apparently in your case when you send the non-CAS OS 4.5 it does remove itself on its first boot.
I don't know why, such behaviour hasn't been reported in this topic.

Maybe the boot2 partition is so corrupted that the boot2 updater fails, thus making the OS fail the "discrepancy check" and reboot.

The downgrade protection works even with no OS at all

cool. How did you get them to do that? They normally don't replace calculators that have been modified. Still don't know what happened to yours because this tutorial has worked perfectly for a lot of people
