And the old version modbo 2.1 does not work to in a V3 - V4 - V10 ( PAL) but connecting H wire solved the V10 PAL problem, this solution was never to find on the diagrams on the modbo website.
Modbo 2.1 works fine in a V4R and up.
Modbo team reported that the first batch 760 had a V10 problem but now was it solved with their new batches.
The 2.1 modbo had a redscreen problem and the modbo team had a bridged reset resistor solution on his website with a picture of a Myth chip !! and this solution had zero effect anyway.
After a few emails to the modbo team I dont expect much support from them when it comes to wich versions mainboard are compatible or not and their fixes.
