What is a B84 file?
A B84 file is an update file used to update Texas Instruments TI-84 Plus CE and CE-T calculators. It contains updates for a calculator's operating system and applications. B84 files are installed using Texas Instruments TI Connect CE, a desktop app used to manage the TI-84 Plus family of graphing calculators.
The TI-84 Plus family of graphing calculators are tools that middle school, high school, and college students use to plot functions, analyze numerical data, solve complex equations, and perform other mathematical operations. The TI-84 Plus CE and CE-T graphing calculators are notable for having screens that display colors, which helps users visualize data.
TI-84 Plus calculators use a unique operating system (OS) and applications. To update a TI-84 Plus CE or CE-T's OS and applications, a user must download the most recent B84 update file from Texas Instruments' website and install the file on their calculator. B84 files are installed on calculators using TI Connect CE, a desktop app that allows users to manage and update their calculators from their PCs.
NOTE: Before using a B84 file to update your calculator, you should use TI Connect CE to create a copy of any important files your calculator contains. Updating your calculator may overwrite your files.
How do I open a B84 file?
To install the updates a B84 file contains on your TI-84 Plus CE or CE-T calculator, you must:
- Open TI Connect CE.
- Connect your calculator to your computer (and make sure it appears in TI Connect CE).
- Drag your B84 file to TI Connect CE's Calculator Explorer.
TI Connect CE will then begin updating your calculator's OS and applications. Your calculator may reboot during the update process.
