Hi all, Is it possible to edit an .rfs or .img file? I downloaded a ROM for my Samsung Galaxy S from samfirmware, I extracted the file and I found inside 6-7 files like boot.bin, factoryfs.rfs, cache.rfs, param.lfs etc. Also some ROMs I downloaded doesn't have .rfs files, instead they have .img files. Im using Ubuntu and Windows 7. How can I access and edit those files? Thanks!
