Updating your Steam Deck OLED keeps SteamOS running smoothly and gives you the latest features, driver improvements, and bug fixes. The process takes anywhere from a few seconds to 15 minutes depending on the patch size and your internet speed.
SteamOS checks for updates automatically when the Deck is awake and connected to WiFi or ethernet, but you can also trigger a manual check whenever you want. Here's everything you need to know about updating the Steam Deck OLED, plus how to handle the occasional hang-up.
Check Your Current SteamOS Version
Open Settings > System and scroll down to the About section. Your current version is listed there. As of April 2026, the stable branch is SteamOS 3.7.21, while the Preview/Beta channel runs SteamOS 3.8.1 (nicknamed "Second Clutch").
Knowing your exact version helps if you're troubleshooting a game that just started acting weird after an update. If you're on stable and want to try the preview channel, you can opt in from Settings > System > Beta Participation. Just be aware preview builds can have their own bugs.
Update Over WiFi (The Easy Way)
Make sure your Deck is connected to WiFi first. Open Settings > Internet and confirm a network shows as connected. Then head over to Settings > System > System Updates.
Tap Check for Updates. If one is available, you'll see the new version and a download button. Hit that and let it do its thing. The download takes 1 5 minutes on a decent broadband connection, then the install runs another 3 10 minutes. The Deck restarts automatically when it's done.
Update Over Wired Ethernet (Faster for Big Patches)
The Steam Deck OLED doesn't have a built-in ethernet port, but you can add one via the official Steam Deck Dock or any USB-C hub with gigabit ethernet. Plug the dock into the Deck and connect a Cat5e or Cat6 cable from the dock to your router.
The Deck automatically prefers wired over WiFi when it detects ethernet. Confirm the connection in Settings > Internet (it shows "Ethernet" under active connection). Then run the update from Settings > System > System Updates. Wired downloads can be 5 10x faster than handheld WiFi, especially for larger updates that include graphics driver bundles.
Enable Automatic Updates So You Don't Have to Check
If you'd rather not think about it, turn on auto-updates. Go to Settings > System > Updates and toggle Enable automatic updates on. Your Deck will download updates in the background when it's online, then prompt you to install on the next restart.
This only works if the Deck stays connected to the internet. If you regularly put it in Airplane Mode or keep it powered off for days, you'll need to manually check every few weeks.
What a SteamOS Update Actually Includes
Valve ships system updates with bug fixes, security patches, graphics driver improvements, and occasional new features like VRR pacing fixes or hibernation support. The SteamOS 3.8 preview, for instance, adds Steam Machine prep, updated graphics drivers, VRR pacing fixes, and BIOS v133 hibernation support.
Minor updates (3.7.21 to 3.7.22) are usually small bug fixes and stability patches. Major version jumps (3.7 to 3.8) bring bigger changes like new kernel versions or UI improvements. Some updates also include firmware for the controller or the internal Wi-Fi module.
Fix a Stuck Update
If a download stalls partway through and won't resume, do a force restart. Hold the power button for 10 seconds until the Deck shuts off completely. Then tap the power button once to boot back up and try the update again from Settings > System > System Updates.
The Deck picks up from where it left off, so you don't lose all the existing download. If it still hangs, reboot your router: unplug it for 30 seconds, plug it back in, and wait a few minutes for everything to come back online. Router-side DNS or DHCP issues are actually the most common cause of a stuck update, especially during peak evening hours.
Free Up Storage Before a Big Update
Large system updates need temporary scratch space on the internal drive, usually 1 2GB. If your Deck's internal storage is nearly full, the update may fail with a vague error like "not enough space" or just hang without a message.
Open Settings > Storage and sort by size. Consider moving some games to a microSD card (the OLED model supports UHS-I SD cards) or deleting anything you haven't played in a while. Your saves are kept separately via Steam Cloud, so you can always reinstall later. Aim for at least 5GB free before retrying a stubborn update.
Switch DNS Servers If the Update Won't Find the Server
If the update check times out or shows "unable to connect," your ISP's DNS might be lagging or misrouting Valve's update servers. Open Settings > Internet > Network and select your WiFi or ethernet connection. Choose DNS Settings and switch from Automatic to Manual.
Enter Cloudflare (1.1.1.1 and 1.0.0.1) or Google (8.8.8.8 and 8.8.4.4) as Primary and Secondary. Save and reconnect. Then run the update check again. Public DNS usually resolves the issue within a minute. This also helps if games have trouble connecting to multiplayer services.
Use Recovery Mode as a Last Resort
If the Deck boots but the regular update path fails repeatedly even with a clean router and DNS, you can reimage the system. This is more involved than the other fixes, but it's Valve's official fallback when software is corrupted.
You'll need a USB-C drive (at least 8GB) and a computer to download the SteamOS recovery image from Valve's website. Write the image to the drive using a tool like Rufus (Windows) or dd (Linux/macOS). Then plug the USB-C drive into the Deck, hold the Volume Down button, and tap the Power button. The Deck boots into the recovery menu. Choose Reimage SteamOS to install a fresh copy of the latest stable OS. This wipes your user data, so make sure any important game saves are backed up to Steam Cloud first.
After the reimage completes, the Deck reboots and walks you through setup again. Once you log into Steam, your library and saves sync back down automatically.
