Firmware Modification KitAGREE TO THE FOLLOWING EULA TO USE THIS KIT OR LEAVE NOW! THIS IS IMPORTANT STUFF, SO PLEASE READ IT. YOU WILL VERY LIKELY BRICK YOUR ROUTER WITH USE OR MISUSE OF THIS KIT. THIS KIT IS FOR ADVANCED USERS WHO CAN RECOVER FROM THOSE BRICKS, PAYING CLOSE ATTENTION TO WHAT THEY ARE DOING. IT IS NOT TO BE USED HASTILY, OR WITHOUT SUFFICIENT KNOWLEDGE. IN SOME CASES RECOVERY COULD BE IMPOSSIBLE. IN THOSE CASES, YOU HAVE LOST YOUR DEVICE. DO YOUR HOMEWORK FIRST. WE CAN DO ONLY SO MUCH TO PROTECT YOU FROM YOURSELF, AND MAKE NO GUARANTEE WE EVEN TRIED TO PROTECT YOU FROM YOURSELF. WE JUST DO THIS ON A VOLUNTEER BASIS FOR THE COMMUNITY. NO WARRANTIES ARE GIVEN, EXPRESSED OR IMPLIED. USE AT YOUR OWN RISK, AND BY USING THIS KIT YOU AGREE TO ACCEPT ALL LIABILITY FOR DAMAGES, TANGIBLE AND INTANGIBLE, RESULTING FROM THE USE OR MISUSE OF THIS KIT READ THE ABOVE AGAIN BEFORE USING THIS SOFTWARE. YOU ARE GOING TO BRICK YOUR ROUTER. WHILE YOU MAY NOT, IT IS BETTER WE SAY YOU WILL SO THAT YOU UNDERSTAND THE RISK. MOST BRICKS ARE RECOVERABLE, BUT NOT ALL. LEGAL WARNING: THIS FIRMWARE MOD KIT MAY ONLY BE USED ON PRODUCTS TO WHICH YOU ARE LICENSED OR ENTITLED TO MODIFY FOR LEGAL PURPOSES. PLEASE CHECK APPLICABLE LAWS, AND MAKE SURE YOUR INTENT IS LEGAL. AS WITH ALL DEVELOPER TOOLS, IT CAN BE USED OR ABUSED. DO NOT ABUSE THIS TOOL. THIS FIRMWARE MOD KIT IS FOR LINUX BASED FIRMWARES ONLY This kit gives the user the ability to make changes to a firmware image without recompiling the firmware sources. It works by extracting the firmware into its component parts, then extracting the file system image. The user can then make modifications to the extracted file system, then rebuild the firmware image. It is most useful for quick debugging of problems without having to rebuild the entire firmware image. It can even be deployed 'on the road'. A variety of formats are supported, mainly linux based GPL images known to be around; additionally, it can be used to customize DD-WRT web GUIs. We've written a few custom utilities (i.e. untrx, wrt_vx_imgtool, spliter3) to support various devices. We've also made modifications to squashfs-tools and added known variants of squashfs-tools. Recently, Binwalk was also integrated, to help identify and support even more firmware types and segment/filesystem types. NO GUARANTEE IS PROVIDED. WITH EVERY REBUILT IMAGE YOU STAND THE CHANCE OF BRICKING YOUR DEVICE (EITHER A SOFT OR HARD BRICK). DO NOT USE THIS TOOL IF YOU CAN NOT RECOVER FROM SUCH A BRICK. BY USING THIS TOOL YOU ASSUME LIABILITY OF ALL DAMAGES, TANGIBLE AND INTANGIBLE, RESULTING FROM THE USE OR MIS-USE OF THIS SOFTWARE. Un-guaranteed support fir firmware image formats for the following devices:
Some specific firmware types:
The following filesystems can be extracted and assembled:
This utility has recently taken on a new contributor who wrote his own new rendition of the extraction and rebuild scripts and inclusion (or creation) of related tools. His are superior at identifying more types of firmwares. His scripts have the -ng.sh filename. The original scripts are still necessary and could work on some firmware images that the newer scripts may not work on. Therefore, they are being kept around, at least for now.
