Ti-Nspire CX CAS

[SomeoneSpecial99]

Hello,

I was wondering if anyone knew how to downgrade the OS on a Ti-Nspire CX CAS, It was running v2.something when i got it and i tried to upgrade it to v3.1 and fell for a lie made by the Ti-Nspire website ... It was actually v3.5... I read somewhere that if the last letter of the serial code is lower than I that it is down gradable... The last 5 digits of my Serial Number are "0911D"

Any help in any way is appreciated.

Thanks

PS. I know about the new version of NDless but it seems to crash every 5 minutes when I have it installed

Even recent hardware revisions can be downgraded, but not with any version. That's the only difference.

I have run into a problem:

The link to nsNandMgr (archives_voir.php?id=10080) is private to me

"Information

I tried to use a copy of nsNandMgr from ticalc.org but my calculator crashed the second i opened the file

So is there no currently known way to set the minimum version installable to 0.0.0?

We are working on making previous method more reliable.
Other ways exist... but they are even harder and use external material.
