Hi,
I have just linked my ROYAL pro12 to the launcher again. It shows that it is updated to the last version (3.56). The launcher identifies the transmitter as a ROYAL pro12 although the software is identical to the ROYAL SX 16. The display on the transmitter also shows that it is a ROYAL pro12 (screen 3) on the first screen it shows SX 16, however.
With my transmitter there has never been any trouble in updating it to what ever software version in the course of time. According to what ever I have read on the ROYAL evo and pro there should be no problem in updating especially when a version higher than 3.30 has already been instalt on the transmitter.
So I am at the end of my wisdom: a member of the MUPTLIPEX-team may offer more help!
So long
