R4i Gold Team and the Acekard Team aren't even the same team.
Where is your proof, because i have mine and im 100% sure about what i'm talking about !
Acekard release a first R4i since a long time ago, called "R4i Ultra", and after this one,
they release R4i GOLD who use WOOD, the firmware are exactly the same then a Acekard 2i,
like the R4i Ultra... Do you want to check it
Maybe you can check this pack ->

One time, Acekard.com made a batch of Acekard 2i, but impossible to upgrade with a regular firmware for Acekard 2i,
so they give to some "Resellers" this pack, when a regular firmware dont work, they can use an other firmware !
Sorry
