- Description: Black screen after a SteamOS update? Hold "..." and power to boot the previous version, games kept, then make it stick or repair SteamOS from USB.

*Updated 28 October 2026\. Checked against Valve's SteamOS Recovery and Troubleshooting and SteamOS Installation and Repair pages, the SteamOS 3.9 release notes, Valve's SteamOS bug tracker on GitHub, the Decky Loader docs, the Arch Wiki and iFixit.*

Short answer: if your Steam Deck shows a black screen after an update, give it up to half an hour first, because SteamOS can still be applying the update with nothing on screen. If it's still black after that, hold the power button for 10 seconds to switch it off, then hold the **"..."** button and press power. Keep holding "..." until the **SteamOS** boot menu appears, and pick the line that starts with **Previous**. That boots the SteamOS version you had before the update, and Valve says your games and saves stay where they are.

That rollback fixes most cases of a Steam Deck black screen after an update. The rest of this guide covers the cases it doesn't: encrypted Decks on SteamOS 3.9, Decky plugins, a dead internal screen, and the USB repair route if nothing boots at all.

## Why Steam Deck black screens are coming up now

Valve pushed [SteamOS 3.9.5 to everyone on the Stable channel on 23 October](https://store.steampowered.com/news/app/1675200?ref=blog.harshkohli.com). It's a big one: a new Arch Linux base, Linux kernel 7.2, Desktop Mode jumping from KDE Plasma 6.4.3 to 6.7.3, a new default Wi-Fi backend and a bootloader update. Most Decks take it without a fuss, but when this much of the system changes at once, a few machines are going to break.

The black screen problems I could actually confirm come from Valve's own bug tracker:

- **SteamOS 3.9.3 beta (16 October).** Owners who had encrypted their home folder with dirlock got a login screen that flashed and then went black ([issue #2955](https://github.com/ValveSoftware/SteamOS/issues/2955?ref=blog.harshkohli.com)). The same bug stopped Desktop Mode opening on a Steam Deck OLED ([issue #2965](https://github.com/ValveSoftware/SteamOS/issues/2965?ref=blog.harshkohli.com)). A SteamOS developer said it was fixed in 3.9.4, and the person who reported it confirmed their Deck booted again after updating.
- **SteamOS 3.9.5 stable (from 23 October).** A new report, [issue #2998](https://github.com/ValveSoftware/SteamOS/issues/2998?ref=blog.harshkohli.com), opened on 27 October, describes a dirlock-encrypted Steam Machine sitting on a black screen after the logo on some cold boots. It's still open, so there's no fix yet.

To be fair to Valve, I haven't seen a wave of 3.9.5 black screens from people with normal, unencrypted Decks. But "black screen after update" has been one of the most common Steam Deck complaints since the launch, and the rollback below works whatever the cause. The tracker also has other 3.9 regressions, such as [5 GHz Wi-Fi trouble on some OLED models](https://github.com/ValveSoftware/SteamOS/issues/2992?ref=blog.harshkohli.com). The same rollback is the way out for those too.

## Match your symptom

Figure out which kind of black screen you've got before you start, because the fix depends on it:

| What you're seeing                                             | Likely cause                             | Where to start                |
| -------------------------------------------------------------- | ---------------------------------------- | ----------------------------- |
| Black screen right after tapping Apply or Restart, fan running | Update still installing                  | Step 1: wait up to 30 minutes |
| Steam Deck logo, then black forever                            | Broken update or display session crash   | Step 2, then Step 4           |
| Password or PIN screen flashes, then goes black                | dirlock encryption bug in SteamOS 3.9    | Step 6, then Step 4           |
| Game Mode loads for a few seconds, then crashes or loops       | Decky Loader plugin broken by the update | Step 7                        |
| No backlight at all, but you hear the chime or feel haptics    | Firmware or display, not SteamOS         | Step 3, then Step 8           |
| Nothing boots, not even the "..." menu                         | Damaged OS install                       | Step 9                        |

## Step 1: Give the update time to finish

Boring advice, I know. Still, [iFixit's Steam Deck black screen guide](https://www.ifixit.com/Troubleshooting/Steam%5FDeck/Black+Screen/520878?ref=blog.harshkohli.com) points out that after a software update the fan can whir away for 30 minutes or longer while the screen shows nothing. Forcing it off in the middle of that is how a slow update turns into a broken one.

So put the Deck on its charger, leave it alone for 30 minutes, and only move on if nothing has changed.

## Step 2: Force a full shutdown

Hold the power button for a full 10 seconds. Valve uses this in its own recovery steps because a short press only sends the Deck to sleep, and a sleeping Deck with a black screen looks exactly like a crashed one. Wait a few seconds, then press power normally.

If it boots, you're done. If the logo shows and then it goes black again, go to Step 4\. You'll need the full 10-second shutdown again there anyway.

## Step 3: Check if it's the screen or SteamOS

Before blaming the update, make sure the Deck is actually showing anything. Two quick checks:

- **BIOS menu.** With the Deck off, hold **Volume Up** and press **power**, then let go of Volume Up when you hear the chime. If the boot menu shows up, the screen works and the problem is in SteamOS. Pick Continue or power off and go to Step 4.
- **External display.** Connect a dock or USB-C to HDMI adapter and a TV. If the TV shows Game Mode but the Deck's own panel stays dark, it's a screen or firmware problem, not the update. Step 8 is the next thing to try, and after that, Steam Support.

If neither the BIOS menu nor a TV shows anything, and the power LED doesn't come on when you plug in the charger, the Deck may be in battery storage mode. It won't respond to the power button in that mode. According to [iFixit](https://www.ifixit.com/Guide/How+to+Enable+Steam+Deck+Battery+Storage+Mode/149962?ref=blog.harshkohli.com), plugging in the charger brings it out of storage mode.

## Step 4: Roll back to the previous SteamOS version

This is the main fix. SteamOS keeps two copies of the operating system, called A and B. When an update installs, it goes onto the copy you're not using, and the old one stays put. If the new copy breaks, you can boot the old one. Valve's [SteamOS Recovery and Troubleshooting page](https://help.steampowered.com/en/faqs/view/1B71-EDF2-EB6D-2BB3?ref=blog.harshkohli.com) says rolling back this way keeps your user data, including installed games and saves.

1. Plug the Deck into its charger. Valve recommends doing this on power.
2. Hold the power button for 10 seconds so it's fully off.
3. Hold down the **"..."** button (under the right trackpad) and press **power**.
4. Keep holding "..." until a black menu titled **SteamOS** appears.
5. Use the D-pad to highlight the line that starts with **Previous** (the second line), and press **A**.

The SteamOS menu you get by holding "..." while powering on. Pick the line that starts with Previous. Image: Valve (Steam Support)

The version numbers next to Current and Previous show you exactly what you're switching between. If you went straight from the old stable release to 3.9.5, Current should be the 3.9.5 build and Previous should be 3.8.28\. The menu also lists both versions with "+ Boot Menu", which you don't need here.

Stay away from **ERASE USER DATA FROM DECK** at the bottom of the list. It wipes your local games and data, and it won't help with an update problem.

If the Deck boots normally on the previous version, you've confirmed the update is the problem. Check what you're on under **Settings > System**.

## Step 5: Make the rollback stick

There's a catch that confuses a lot of people. Choosing Previous in the menu is a one-time boot. A SteamOS developer on the [SteamOS tracker](https://github.com/ValveSoftware/SteamOS/issues/1678?ref=blog.harshkohli.com) noted that the Deck goes back to the newest version on the next reboot. So you either have to pick Previous every time, or make the older copy the default.

To make it the default, boot into the previous version, then press the Steam button and go to **Power > Switch to Desktop**. Open **Konsole** and run:

```
sudo rauc status mark-active booted
```

That tells RAUC, SteamOS's update tool, to treat the copy you're running now as the active one. If `sudo` asks for a password you never set, run `passwd` first and create one.

Two things to keep in mind. First, Settings will keep offering you the update, so don't tap Apply until a fix is out. Second, SteamOS only keeps one spare copy, so installing any update writes over the older version you just rolled back to. That's fine once the new build actually works.

## Step 6: Encrypted home folder (dirlock) on SteamOS 3.9

If you set up dirlock home folder encryption, you'll know it, because you type a password on a login screen every time the Deck starts. That login screen is exactly where the 3.9 bugs show up.

- **On the 3.9.3 beta:** that's the bug Valve fixed in 3.9.4\. If you're stuck on 3.9.3, roll back with Step 4, then update. Anything from 3.9.4 up, including the current 3.9.5, has the fix.
- **On 3.9.5 stable:** the open report (#2998) says the black screen shows up on some cold boots, after the logo. The owner got the login screen back by forcing the machine off and starting it again four or five times. Until there's a fix, you can do the same, or roll back with Steps 4 and 5 and wait for the next update.

Valve still calls dirlock support "experimental" in its release notes, so expect rough edges with every major update.

## Step 7: Clear out Decky Loader plugins

If Game Mode shows up for a few seconds and then crashes, hangs or restarts in a loop, look at [Decky Loader](https://github.com/SteamDeckHomebrew/decky-loader?ref=blog.harshkohli.com) before you blame SteamOS. Decky's own readme warns that it can break on SteamOS updates, and its tracker has threads where a single outdated plugin [stopped Decky from starting](https://github.com/SteamDeckHomebrew/decky-loader/issues/829?ref=blog.harshkohli.com) or [left Decks stuck in a boot loop](https://github.com/SteamDeckHomebrew/decky-loader/issues/857?ref=blog.harshkohli.com).

If you can get to Desktop Mode, move your plugins out of the way and reboot:

```
mkdir -p ~/homebrew/disabled-plugins
sudo mv ~/homebrew/plugins/* ~/homebrew/disabled-plugins/
```

If Game Mode is stable after that, put the plugins back one at a time until you find the one that breaks it. Then check the Decky store for an update to that plugin, or leave it out. To remove Decky completely, the readme's quick method is to run its uninstall script from Konsole:

```
curl -L https://github.com/SteamDeckHomebrew/decky-installer/releases/latest/download/uninstall.sh | sh
```

If Game Mode won't stay up long enough for you to switch to Desktop Mode, roll back with Step 4\. The previous SteamOS version usually gets you far enough to clean things up.

## Step 8: Reset the BIOS settings

This one is for the "no backlight, but it's clearly on" case from Step 3\. The [Arch Wiki's Steam Deck page](https://wiki.archlinux.org/title/Steam%5FDeck?ref=blog.harshkohli.com) describes a reset of the UEFI (BIOS) settings to their defaults:

1. Switch the Deck off completely.
2. Hold **Volume Down** and **"..."**, then press **power**.
3. When the LED blinks the first time, let go of power but keep holding the other two. The LED keeps blinking while it resets. When it stops, let go.

It can take a while, so leave it on the charger. If the internal screen is still dark after that but a TV works, contact [Steam Support](https://help.steampowered.com/en/wizard/HelpWithSteamDeck/?ref=blog.harshkohli.com). At that point it's more likely hardware or firmware than anything you can fix with a rollback.

## Step 9: Repair SteamOS from a USB drive

If the "..." menu won't load either version, the last resort is Valve's recovery image. Its [SteamOS Installation and Repair page](https://help.steampowered.com/en/faqs/view/65B4-2AA3-5F37-4227?ref=blog.harshkohli.com) covers the full process. In short:

1. On another computer, download the SteamOS recovery image from that page and write it to a USB drive of at least 8GB. Valve suggests Rufus on Windows and balenaEtcher on macOS or Linux.
2. Switch the Deck off and plug the drive in, using a USB-C adapter or hub.
3. Hold **Volume Up** and press **power**, let go when you hear the chime, then pick **Boot Manager** and choose **EFI USB Device**.
4. Wait a minute while it boots to a desktop. Then choose **Repair SteamOS**.

Repair SteamOS reinstalls the OS and tries to keep your games and personal files. **Re-image Device** and **Wipe Device & Install SteamOS** erase everything, so only use those if Repair fails. Many games sync saves through Steam Cloud, but check before you wipe anything, especially for emulators and non-Steam games.

## How to avoid this next time

- **Stay on Stable unless you want to test.** Both 3.9 beta bugs above hit Beta and Preview first. You can switch channel under **Settings > System > System Update Channel**.
- **Update Decky before you update SteamOS,** and remove plugins you don't use anymore.
- **Don't interrupt an update.** Keep the Deck on the charger and let it reboot by itself.
- **Remember the "..." menu.** It's the quickest way out of a bad update, and most owners don't know it's there.

SteamOS isn't the only system that can be rolled back after a bad update. If a Windows update broke your PC, see my guides to [fixing the KB5127648 boot loop](https://blog.harshkohli.com/kb5127648-boot-loop-fix/) and [getting a stuck Windows Update moving](https://blog.harshkohli.com/windows-update-stuck-fix/). SteamOS 3.9 also removes the compromised eMudhra certificates that Microsoft just dropped from Windows. I covered that in [this news post](https://blog.harshkohli.com/windows-update-removes-emudhra-certificates/). And if Steam keeps crashing on launch on a Windows PC with an AMD Radeon card, here's [how to fix the Steam crash on AMD](https://blog.harshkohli.com/steam-crashing-on-launch-amd-radeon-fix/).

Thinking of replacing your Deck instead? I compared it with the newer Windows and SteamOS handhelds in [Steam Deck vs ROG Xbox Ally X vs Legion Go S](https://blog.harshkohli.com/steam-deck-vs-rog-xbox-ally-x-vs-legion-go-s/), with current prices in USD and INR.

## FAQ

### Will rolling back SteamOS delete my games?

No. Valve says rolling back to the previous OS keeps user data, including installed games and saves. Only the operating system changes. Just don't pick "ERASE USER DATA FROM DECK" in the same menu.

### Why does my Steam Deck go back to the new version after a reboot?

Picking Previous in the "..." menu only applies to that one boot. To keep the older version, boot into it, open Konsole in Desktop Mode and run `sudo rauc status mark-active booted`.

### How long does a Steam Deck update take?

Usually a few minutes, but iFixit says the screen can stay dark for half an hour or more after a software update while the fan runs. Give it 30 minutes on the charger before you force it off.

### Is SteamOS 3.9 safe to install on Steam Deck?

For most people, yes. It's been the stable release since 23 October, and the black screen bugs I found mostly affect Decks with dirlock encryption. If you use encryption or rely on 5 GHz Wi-Fi on an OLED, watch the [SteamOS issue tracker](https://github.com/ValveSoftware/SteamOS/issues?ref=blog.harshkohli.com) before updating, or keep 3.8.28 as your fallback.

### How do I get my Steam Deck off the beta channel?

Go to **Settings > System > System Update Channel** and pick Stable. Changing channel doesn't downgrade you by itself, so if a beta build is broken, roll back first with the "..." menu and then change channel.

## Still stuck?

Tell me in the comments which Deck you have (LCD or OLED), what SteamOS version the "..." menu shows for Current and Previous, and whether you use encryption or Decky. If a pattern shows up, I'll add it here.
