Img4helper

Img4Helper is a small tool built for handling Apple’s Image4 format used for the boot files in iOS/iPadOS and other operating systems built by Apple. It’s purpose is to make analysis, decryption, decompression and extracting these files easier. Img4Helper (and Libhelper) are open-source, so please check it out of Github where I have a more in-depth discussion of the tool.

Special thanks to @tihmstar and @xerub. Although they did not personally help me with this project, by open-sourcing both img4tool and sepsplit they made this possible.

Changelog

This is the first non-Beta Release of Img4helper. Thank you for using Img4helper, please Tweet me @h3adsh0tzz with what you think and/or if you have any issues. You can checkout the usage documentation on Img4helper’s Github.
