Backup bootloader only and flash samsung devices

[emremutlu]

I have a samsung P902 tablet which is specified version for P901 galaxy note pro 12.2". P902 version doesn't have stock rom or getting any update. Meanwhile P901 got android 5 recently. P901 and P902 has same hardware. So i need to update the bootloader to newest to use lollipop roms on my P902 device. Since there isn't a stock rom i need to keep myself safe. So is there a easy way to backup bootloader and make it flashable via odin or heimdall? Any information could help.
