Whats the Difference between FS and Main?

[gyuszko]

i have a lil question.... with phone xs what do you flash first? the Main or the FS? ... i usualy flash the main first... and sometimes the phone hangs... why?

I'm using cruiser in most cases, and with K750 CID49RED when you remove RSA and after that trying to flash main, flashing hangs, but when I remove RSA and after that right restore FW (you know, first 256K of FW), I can flash main without any problems.

Fs is package or phones extra feature and prodcut special.
its like contant file or datapackage which includes extra facility..
like images sounds..themes views

where main arm or firmware is main OS which affects phone speed.
working accuracy. processs management.bugfixing.and manythig more as
out pcs software..

I hope i cleared...
