Looking for help extracting files from stock tar.md5 on the S6.

Hey so I wanted to extract the modem/bootloader files from the latest tmobile stock S6 rom seen as I can't find them posted anywhere.

My question is, are there specific steps I need to take to do this on the S6? As far as I know, I need to extract the tar.md5 get sboot.bin and modem.bin and then re-compress them as tar. Do I just rename them tar.md5 in order to use in odin or am I missing a step?

Any tips on extracting the full rom from the tar.md5 would be awesome too. I've been trying to find a guide that works for the S6 if anyone has one they use. I keep getting problems with mounting the img files.

Thanks
