I updated the OS of my ti nspire cx calculator

[Block-Flock]

I think before it was 3.6 but then I clicked some press to test thing and followed some tutorial to fix that and clicked send os and now im stuck with an os that I cant jailbreak which is 4.5.5 so is there any way for me to get this fixed?

If you are on 4.5, upgrade to 5.2 or 5.3 and you can install Ndless, right ?

If you are on 4.5 just update to 5.2 or 5.3 and you can install Ndless.

lol no 4.x are for CX models and 5.x and later for CX II models, exclusively.

With a serial cable you might be able to install nLoader and downgrade that way.

Yeah maybe, I also found out I can delete the OS for the nspire by pressing some buttons

That will not reset the downgrade protection.

Oh yeah, I have a serial cable but it's an RS232 male and my PC has a Male port for it too and I don't have a RS232 female to female wire to plug it in my PC. Anything else that I can try? Or do I wait for Ndless 4.5.5.79?

yooo please upgrade ndless for 5.4 dang it

[Lockl00p]

yooo please upgrade ndless for 5.4 dang it

While I do need this, I understand that the entirety of ndless is just finding an exploit that works, and thus could take a year

yooo please upgrade ndless for 5.4 dang it

We've said this so many times before. We don't know when it's going to be, We do know that fabian is still working on it. stop re-opening duplicates of #300. we have enough.

Sorry if I seemed a bit annoyed, I just have so many emails of the same things.
