## Updating device operating systems

Use TI Software Update to update device operating systems. Updating your operating system can give your device new features, support for new accessories, and improved performance. You can update device operating systems from normal or merged view.

Warnings:

| • | Updating an operating system erases all data on your calculator.

| • | Do not disconnect a device during an OS update.

### Before you start

| • | Make sure your device is properly connected to your computer.

| • | Make sure your device has good or new batteries.

| • | If you are in normal view and cannot see the device software files, click the arrow to the left of the device.

### To update device operating systems

| 1. | Back up your device. (See the TI Device Explorer help.)

| 2. | If the main window shows free updates, click View > Hide Free Updates or click Hide Free .

TI Software Update hides the available free updates.

| 3. | Click the box next to the operating system.

A check mark appears in the box.

| 4. | Click Update > Update Checked Items or click Update .

| 5. | Click Proceed.

| 6. | Read the license agreement, and then click Agree.

TI Software Update downloads the operating system to your device and stores a copy of it on the computer (by default, it stores it on your desktop). When the software finishes the download, a green check mark appears next the operating system file in the main window.

Note: If you want to view the update progress, show the log. (See Showing and hiding the log.)
