XS++ 3.1 Guide-Flashing, Customizing, Recovering

[shondown]

Hi guys... just a quick question here...

My K850 (not supported by XS++, I knew... but plz... bear with me...) currently using CHINA_SO R1CA029.

Lets say I am to change the phone to GENERIC_S0 R1CA029, can XS++ do it? I noticed the option is there.

Do I need to download anything?

I'm not going to change/customize/edit anything to my current firmware, just to change it from CHINA_SO to GENERIC_SO.

(I'm asking this because apparently SEUS don't have the update for my version of K850, so I thought maybe by changing the above would make it do so)

Thanks in advance!
