Updates and Rollback

This guide covers safe update habits and what to do if a new build causes issues.

Before you update

• Read the release notes for your device family.
• Make a backup of /userdata/ (saves, configs, BIOS, and ROMs).
• Ensure stable power; avoid updating on low battery.

Update options

Use the in-system updater if it is available on your device. This is the safest path because it applies the correct build and preserves your data.

If you prefer a manual update, reflash the latest image for your device and restore your /userdata/ backup afterward.

After updating

• Check the system version in the settings or system info screen.
• Confirm that controllers, audio, and Wi-Fi work before loading large game libraries.
• If you use shaders or overlays, verify that they still load as expected.

Rollback basics

If a new build causes problems, the most reliable rollback is:

1. Reflash the previous image for your device.
2. Restore your /userdata/ backup.
3. Confirm the system boots and your saves are intact.

If you cannot access the UI, try a known-good SD card or USB drive first to confirm the issue is not hardware-specific.
