It relies on a sandbox escape exploit called badquery to inject tweaks, which is why some capabilities (like writing to MobileGestalt) are limited.

Back up your device first since data loss is possible even though the tool is tested.

No separate jailbreak is needed; Erosion carries its own sandbox escape exploit to run.Does every tweak work on every supported iOS version?No. On all iOS 26 builds, tweaks that require writing to MobileGestalt (gestalt tweaks) do not work because badquery cannot write to it; only iOS 27 developer/public betas get full functionality.

Any other version is not supported.
Only iOS/iPadOS 26.0 through 26.6.2 (limited functionality) and iOS/iPadOS 27.0 developer/public betas 1 through 4. Any other version is not supported.Why aren't my PosterBoard wallpapers showing up?Try resetting Collections from within the app first. If the wallpaper still doesn't appear, it is likely an issue with the wallpaper file itself rather than something Erosion can fix.
