So "CEX to REX" = updating to 4.21 REBUG REX from 3.55 CEX.... nothing special
Oh ok, I see where I got confused there.
REX and DEX, Rebug and Debug. It is all really just R&D xD hehe
I think I will then possibly goto either the REX 4.21 or Rogero 4.30 v1.4 (I would prefer the 4.30, provided the issues have been resolved).
Rogero has some very nicely documented guides on how to downgrade as well as upgrade again.
Also seems as if the REX FW has a lot of die hard fans and followers.
