Before you begin...
- Please create a backup of your device before usage! While Erosion has been extensively tested, there is still a possibility that you could lose your data by using this tool.
- If a tweak doesn't work how you were expecting, do not open an issue or ask for support regarding it! All tweaks are reliant on your device cooperating properly, and in some cases this can even involve Apple's servers. We'll be unable to help you.
Supported Versions
[!NOTE]
If your version doesn't show up on this list, your device is not supported. Do not ask us for any support regarding extending version support! Exploits that apps like these rely on are very rare to come by, so there's nothing we can do if your device isn't supported.

FAQ
- Why can't I use MobileGestalt tweaks on iOS 26? The exploit that Erosion relies on,
bad_query, is not capable of writing to MobileGestalt, therefore those tweaks do not work. - Why aren't PosterBoard wallpapers showing up? Sometimes, you'll have to reset Collections, which can be done in-app. If the wallpaper still doesn't show up after that, then it's likely a wallpaper-based issue rather than something that Erosion can solve.
