# Firmware Releases

{% hint style="info" %}
**Attempting to reload firmware after upgrading to 1.2.x?**

Releases prior to 1.2.0 were encrypted with an outer key A with an inner encryption key A.\
Starting with release 1.2.0, releases are encrypted with an outer key of encryption key A, but, has a new inner encryption key B.

If you attempt to re-upload the 1.2.x firmware it will fail to decrypt as it was signed and encrypted with key A.

You must load the other 1.2.x → 1.2.x releases of your choosing in the right two tabs as those releases were signed/encrypted with key B.

## What Version Is Required For Official Competitions?

Radios must be updated to at least 2.0.0 to be used at official events in the 2026 FIRST FRC Competition season. If your radio is running a version prior to 2.0.0, it will be upgraded to the latest version when you use the Radio Kiosk at an official FIRST event.
