reimagine

This tool can be used for decrypting IMG files, listing, dumping their tags and patching their contents (using ibootsup from opensn0w-X).

Licensed under GNU GPL.

Usage: reimagine <infile> [<outfile>] <options>

<options> are:
	-iv <IV>	set IV for decryption
	-k <key>	set key for decryption
	-d, --dump	print tag names and hexdump their content
			(Note: this option works on the final decrypted/patched file)
	-l, --list	list tags present in file
	-r, --raw	dump the DATA tag to <outfile>
	-p, --patch	patch the file using ibootsup
	-x, --decompress	decompress lzss compressed kernelcache

Thanks to winocm for opensn0w-X, guys behind xpwntool and decodeimg3.pl for decryption logic, J from newosxbook.com for device tree headers.

#Example usage

• Pwned iBEC for kloader reimagine iBEC.n90ap.RELEASE.dfu -k ... -iv ... -p -r
• Pwned iBoot for iBEC reimagine iBoot.n90ap.RELEASE.img3 -k ... -iv ... -p
• Decrypt kernel and extract into MachO file reimagine kernelcache.release.n90 kernel.macho -iv ... -k ... -x -r
