What is the Steam Deck BIOS Manager?
The Steam Deck BIOS Manager is a handy shell script that greatly simplifies many BIOS-related tasks on the Steam Deck.

You can find the download on GitHub - click here.
Instead of cryptic terminal commands, SteamOS lets you back up, flash, lock, or unlock your BIOS with a clear menu navigation - all with just a few clicks. Perfect for anyone who wants to customize their Steam Deck or experiment with custom firmware.
Functions and Features
- Backup: Quickly create a backup of your current BIOS - in case something goes wrong, you're on the safe side.
- Block/Unblock BIOS Updates: Prevent automatic BIOS updates by SteamOS or re-enable them if you wish.
- Unlock: Unblock hidden menus (e.g. AMD PBS/CBS) and enable the use of tools like Smokeless.
- Download & Flash: Download signed BIOS files directly from a verified source and flash them safely to your device.
- Crisis Mode: Prepare a USB stick for restoring your BIOS in case of emergency - especially useful in case of faulty flashing processes.
- Compatibility: Supports both the Steam Deck LCD and the OLED models - including custom BIOS for DeckHD and DeckSight OLED panels.
Instructions for use
- Switch to desktop mode in your Steam Deck and open the terminal (console).
- Clone the GitHub repository:
git clone https://github.com/ryanrudolfoba/SteamDeck-BIOS-Manager.git - Change to the directory and make the script executable:
cd ~/SteamDeck-BIOS-Manager
chmod +x steamdeck-BIOS-manager.sh - Start the script:
./steamdeck-BIOS-manager.sh - Follow the menu instructions. The script checks if a sudo password is set and guides you through the desired functions.
Important: Certain functions require administrator rights (sudo password). If you haven't set one yet, you will be prompted to do so.
Important Information & Safety
- Backup first! Always create a BIOS backup before flashing or unlocking - the script offers a dedicated option for this.
- Use CRISIS Mode with caution: The USB stick will be completely formatted! Do not use a stick containing important data and ensure that no other USB storage device is connected.
- DeckHD & Custom BIOS: The script also supports flashing custom BIOS, e.g., for DeckHD or larger RAM modules. Always check the compatibility and source of the BIOS files.
- No BIOS files included: The script automatically downloads verified, signed BIOS files - you don't need to worry about downloads yourself.
- At your own risk: Modifications to the BIOS are always at your own risk. An incorrect flash can render your device unusable (keyword: "brick").
