There’s more than one way to skin a cat, as the old saying goes, but how many ways are there that only require a few mouse clicks? This can also be said of ripping the cache.img off of any given Android device. Using current methods, developers must get the image file off of a ROM, convert it to EXT4 formatting, then mount it before they can pull anything off of it or otherwise play with it. This requires no fewer than 2 tools, and can include even more. While not the most well known aspect of development, having a tool that cuts all that down to one application is certainly very cool.
Cache Ripper does all of the aforementioned actions in one single interface, allowing developers to more easily grab its contents. XDA Senior Member Grooby, who’s also the application developer, further explains:
get cache.img from rom, convert it to ext4 image, mount and unpack
it takes 2+ tools to do that manually
my tool gets the cache.img and ripp offs the content to zip file, which is easy modificable (you can add regions to it, as well as see/change settings and easly repack to zip) and then flash with cwm as this zip is flashable
It saves all devs (not only SGS3) a LOTs of work, and this tool will be incorporated in kitchens and builders/tweakers
As you may have ascertained, this tool was developed with the currently popular Samsung Galaxy S III in mind, but Grooby states that this application can be used on more devices. Other compatible devices are not specifically mentioned, but given the typical and apparently irritating method in place now, it’s definitely worth a try for just about anyone.
