This feature is particularly useful when you only need to modify a specific component like system.img or boot.img .
But why do we need a "patched" version?

If a partition extracts but refuses to mount as a loop device or open via unsquashfs , the manufacturer may be using a non-standard block size. Try passing the extracted partition through raw hex editors to inspect the initial magic bytes (such as checking for hsqs signatures on SquashFS images) and adjust the file offset manually.

Before beginning, ensure you are working in a safe directory, preferably on a Linux environment (or Windows via WSL) as most file systems inside these binaries utilize Linux permissions. Step 1: Preparation
