Samsung Mondi

[Guest mediapirate]

I have a Samsung Mondi, I've been reading the threads here and considering Samsung has all but dropped further development on the device I'm considering a custom 6.5 upgrade. The only concern I have is none of the current Rom's have support for Wimax and obviously most of them are built with native phone functions. What would I need to do to backup or pull the system files so that if I install a custom Rom I could restore the native Wimax software?
