XS++ 2.x Guide

[ama95]

if i flash my k550 red52 with xs++ v2.2 then i would be able to customize(finalize) it?

I think you need to choose K800 in "Phone Model" if you want to customize K550 with XS++ . I'm not 100% sure. You can flash it with SeTool2Lite. It supports K550 but you need a custpack.
