Project Sandcastle

Project Sandcastle is a proof-of-concept released by the Corellium iOS device emulator project that successfully boots Android on A10-based devices. The project released a port of Android 10, named Sandcastle AOSP, along with a build of Linux, that can be dual-booted on an iPhone 7 or iPod touch (7th generation) via the checkm8 exploit.

The project was unveiled during a time that Corellium found itself in a lawsuit with Apple over claims that the Corellium emulation service violates its copyright over iOS. The name is a reference to breaking out of the sandbox Apple devices force its users into. The project is positioned as a successor to iDroid, given that Corellium co-founders David Wang and Chris Wade were part of the original iDroid team.

It has not seen any activity since 2020, shortly after its initial 2020 release.
