TI Patches ArTIfiCE jailbreak
A couple weeks ago, TI released TI-OS 5.8.5 for the TI 84 Plus CE and the TI-84 Plus CE Python. From experience, this is an unpresidented move by TI, as they typically only patch jailbreaks if a security flaw is discovered (There is no flaw in this case).
Why did TI do this?
Honestly? I'm not sure. My best guess is with finals coming up, they wanted to stick to their "no distractions" tagline.
I upgraded to 5.8.5! What should I do?
There is really nothing you can do. Once you upgrade, your locked in. Your options are really:
-wait for a new jailbreak (could take months or even years)
- Use TI-BASIC for now, or use Python if your calc supports it
- Trade with someone running an older OS if they don't care about ASM/C
- If you bought your calc recently, you might be able to return it, get your money back, and buy a new one (most of them still come with 5.8.2)
If your calc is NOT on 5.8.5:
No action is needed. Just leave the OS alone and don't update.
The good news:
With the release of the TI-84 Evo, this game of cat and mouse is over as the cat has basically moved to a new house.
