Jailbreak allows execution code on TI-84 Plus CE calculator again

A developer has announced arTIfiCE for TI CE calculators with OS 5.5 and 5.6. This allows Assembly code to run on, for example, the TI-84 Plus CE. TI recently deleted that possibility

TI deleted the ASM functionality at OS 5.6 and 5.5 in May to prevent app cheating. That sparked outrage among the homebrew community around TI calculators. According to the creator of arTIfiCE, YvanTT, the jailbreak is not a cheat tool but simply restores functionality that has been in the calculators for years.

He expects TI to undo the jailbreak, but also reports that more bugs have been found that new jailbreaks can be based on. He promises to publish the source code of jailbreak via Github and has provided all found exploits with ‘funny code names’.

TI removed the ability to run ASM on current versions of the TI CE calculator software at a time when videos were popular on the internet explaining how the exam mode could be bypassed on TI CE calculators. The manufacturer would like to maintain confidence in the mode through education. In exam mode, the settings are adapted to the exam and the memory, and thus access to all programs and applications of the graphics calculator, is blocked. The mode is designed to prevent exam fraud
