What is firmware?

Firmware is the software that runs on your device’s hardware. It controls how your device works and interacts with other devices and software. Updating your firmware can improve your device’s performance, fix bugs, and add new features.

Before you begin

Before you start the upgrade process, there are a few things you need to do:

• Backup your data: Before you start the upgrade process, it’s important to backup all your data. This includes your contacts, messages, photos, and anything else you don’t want to lose.
• Charge your battery: Make sure your device has at least 50% battery life before starting the upgrade process.
• Connect to a stable network: Downloading and installing firmware requires a stable internet connection. If possible, connect to Wi-Fi instead of using mobile data.
