[4] In 2012, TI launched the TI-84 Plus Pocket SE, a miniaturized version of the TI-84 Plus Silver Edition for the Asian market.

The TI-84 Plus C Silver Edition was released in 2013 as the first Z80-based Texas Instruments graphing calculator with a color screen.

It had a 320×240-pixel full-color screen, a modified version of the TI-84 Plus's 2.55MP operating system, a removable 1200 mAh rechargeable lithium-ion battery, and keystroke compatibility with existing math and programming tools.

The calculator retains the 320×240-pixel color screen, rechargeable battery, and key layout of the TI-84 Plus C Silver Edition, while removing the 2.5 mm I/O ("DBUS") linkport and moving the USB port and charging LED to the right side of the handheld.

In addition, the RSA signing key length has been increased to 2048 bits, making infeasible previous efforts to unlock the calculator to unrestricted third-party software development.

[10] The calculator comes programmed with seven different languages (English, French, German, Dutch, Portuguese, Spanish, and Swedish).

The only significant difference from the CE model is the addition of an LED that blinks while the calculator is in Press-to-Test mode.

In 2020, TI Education announced its decision to remove support for assembly and C programming on these calculators in response to a video posted on YouTube detailing how to bypass the test mode on OS version 5.2.2.

Currently, an exploit called ArTIfiCE has been released that allows for native code execution through a bug in the CabriJR app.

[16] Around 2021, Texas Instruments removed the charging light to simplify and reduce costs (notably on the black model).

Also, there are several languages developed by community members for the calculators, notably ICE, which is for the TI-84 Plus CE, and Axe, which is for the TI-84 Plus and TI-84 Plus SE.

There are a wide range of applications that this produces, including science classes, games, calculus, and note taking (when put together with a separately sold keyboard).

However, in some cases those administering the exam may reset the calculator's memory beforehand to prevent cheating through the use of built-in programs or other data.

The most noticeable addition to the new OS was the "Press-To-Test" feature that allowed a teacher to disable any programs installed on the calculator, so they cannot be used on tests, etc.

[21] In July 2009, a community-made patch was released which allowed user-made operating systems to be easily uploaded onto the TI-84 Plus series.

In response to this, Texas Instruments released a newer hardware revision which only accepts other, stronger RSA keys, making it harder to load user-made operating systems or older TI operating systems (2.53MP and earlier).

The community has found a way around the newest limitation by discovering a way to revert to older versions of the boot code.

[27] 4 months later, a jailbreak called arTIfiCE, which exploits the application Cabri Jr. to run arbitrary code, was written that restored compatibility.

It supports loading bundles of files, multi-device syncing and exam mode deployment, along with the ability to send OS updates to multiple calculators at the same time, and a built-in IDE for TI-BASIC programming.
