stuck after downgrading boot 2

Hello!

i successfully downgraded boot2 to 1.4.1571, however my ti nspire kept rejecting the new OS, so i just opened the maintenance menu and wiped (formatted) the calculator and retried installing the 2.1.0 firmware. however, this too failed over the "you cannot install an older os than 3.1.0." error

i'm going to remove the boot2 from 3.1.0 and install it again, how do i downgrade below 3.1.0?

Ok, i was digging around a bit and eventually came across the "downgrade fix" package. So i wiped my calculator again and ran it... scared the hell out of me when it stopped responding, even more when after removing the batteries, the screen remained on.

however, a few seconds later the calculator booted! 2.1.0 is installed!

thank you!

is there any way to convert 3.1.1 files into 2.1.0?
