New TI NSpire downgrade?
« on: September 16, 2017, 04:48:27 pm »
I haven't been able to find a thread on the matter that wasn't 2 years or more old. I have a CR4 TI Nspire (serial P-xxxxxA) that has min listed as 4.4.0.532
Is it possible to downgrade this calculator so all the ndless programs aren't running in compatibility mode? Is there even a benefit to doing such?

Compatibility mode is entirely a hardware thing. TI switched the orientation of the LCD in memory, so programs that haven't been updated for Hardware revision W need to have some helper code redraw the screen in the correct orientation. Downgrading the OS won't get you anything.
