jailbreakdotparty/Erosion

What it does

Erosion is a Swift-built iOS customization toolbox that relies on the worse_query sandbox escape to modify system-level appearance and behaviour without a traditional jailbreak. It covers tweaks such as gestalt adjustments, PosterBoard wallpapers, Custom Wallpapers and Dialer Themer. It is aimed at users on supported iOS/iPadOS releases who want deeper customization than stock settings allow.

Because the approach depends on an unpatched exploit rather than a signed entitlement, the feature set is tied to what the exploit can reach on each OS version. The README notes that worse_query cannot write to MobileGestalt on iOS 26, so gestalt tweaks are unavailable there.

Supported versions

• iOS/iPadOS 26.0 - 26.6.2: limited functionality, e.g. no gestalt tweaks.
• iOS/iPadOS 27.0 - 27.2.1: full support as described.
• iOS/iPadOS 27.3 beta 1 (24C5037i).

Anything outside this list is unsupported, and the project explicitly declines requests to extend version support. As of 2026-11-08, worse_query had not been patched by Apple in any shipping release, but the README expects that to change soon, so support is time-sensitive.

Getting started

1. Back up your device first. The README warns that data loss is possible even though the tool has been tested extensively.
2. Confirm your iOS/iPadOS version appears in the supported list above; if it does not, stop here.
3. Download the latest build from the GitHub releases page and install it on the device.
4. Expect the first launch of Custom Wallpapers or Dialer Themer to hang for around 30 seconds while the app detects container paths. This setup is one-time only.
5. For PosterBoard wallpapers that do not appear, reset Collections from inside the app; if they still do not show, the issue is likely with the wallpaper itself rather than Erosion.

Dialer themes and custom wallpapers are distributed separately at cowabun.ga/wallpapers. There is also an official project page and a Discord community.

Constraints and caveats

• Tweaks depend on the device cooperating, sometimes including Apple's servers; when a tweak misbehaves, the maintainers state they cannot provide support, so do not file issues for individual tweak failures.
• The exploit may be patched in a future Apple release, which would end compatibility on newer versions.
• iOS 26 users cannot use MobileGestalt-related tweaks.
• The project is licensed under GPL-3.0 and is a device-side tool; users should treat the operations it performs on system files as potentially destructive.

HotRepo's take

The repository has 651 stars and 90 forks, but no HotRepo daily ranking record, no star snapshots and no Hacker News discussion were captured, so there is no trend or velocity signal to report. What stands out from the project itself is the narrow version matrix: three OS ranges, one of which has limited functionality, plus an explicit expectation that Apple will patch the underlying exploit. That makes this a tool whose usefulness is defined by the current iOS release rather than by ongoing development alone. The README's own emphasis on backups and its refusal to support tweak-level failures also indicate the maintainers expect breakage at the edges more than a polished, fully supported product.
