Picasso kfd exploit-based toolbox app updated to v3.1 with system app icon theming

Picasso, the device customization toolbox app for iPhones and iPads susceptible to the kernel file descriptor (kfd) exploit received another update over the weekend, this time bringing to the tool up to version 3.1. It’s the first major update to the Picasso software since it went free following the TrollStore 2 release.

Picasso v3.1 released.

The latest release, announced via the project’s Discord server by lead developer @sourcelocation, appears to bring with it the following changes:

Icon Theming:

System app icon theming, can be enabled in settings of the Themes tab.

*WARNING* This new icon theming method is very similar to Cowabunga’s – it replaces .png files inside the system apps and temporarily corrupts the Assets.car catalog, rebuilds the icon cache and restores it. While Picasso uses KFD instead of MDC and has an entirely new code, there’s still a chance of bootloops happening. I’d appreciate if someone tests this version on devices you don’t care restoring in case it bricks.

If not enabled in settings, Picasso won’t use this new theming method and will use the safe one instead.

Other:

Improved debugging. In case of crashes, we will now ask for crash logs which should make development easier.

As it would appear, the major change in this update has to do with app icon theming. The new method works similarly to the method used in Cowabunga, and while it works, there’s a risk of boot-loops. Picasso doesn’t have this option enabled by default for the sake of user safety, however users can enable if they’re feeling brave enough to give it a shot.

The Picasso device customization toolbox can be used on any iOS or iPadOS 16.0-16.6 beta 1 device, as these versions of firmware are susceptible to the kfd exploit. You don’t need a jailbreak to take advantage of it, but you can still use it if you are jailbroken.

If you’re already a Picasso user, then you can download the latest .ipa file from the project’s Discord server and install it over your existing installation. Anyone who isn’t already taking full advantage of Picasso can perma-sign it with TrollStore or sideload it with Sideloadly.
