I think it may help if i provide more info. Samsung packed their firmware into files which after extracted are, - boot.bin - modem.bin - slb.bin - param.lfs - normalboot.img - recovery.img - cache.rfs - system.rfs - userdata.rfs
What i guess about these files: - the first 3 files are bootloader, modem and secondary bootloader - have no clue what the param.lfs is. - the .img files are where I should look at (the main & backup kernel+ramfs files, I guess) - the .rfs files are the platform file, I though they are rfs partition images but they are not. Could be some kind of compressed files. when open the .img files, their header started with 'ANDROID'. So I guess they might relate to android project in some way.
