Finally got my Y6 DIY kit with a Tarot 2D. Assembly is done, tarot is attached with the Gopro on it but can't get to configure anything of the Tarot as a Yellow LED blinks 3 times and then off. Nothing happens. Can't get that solid yellow. My tarot 2D is powered with a UBEC 12V as I have a 4S battery connected to my power module. However, I also tried with a 3S battery (w/out ubec) and I got the same blinking yellow.
