Hi all, newbie here. I have bricked my p1 receiver after doing a firmware update. I can no longer use my remote with my p1 at all. I have done the factory reset and made sure it is set to D bus. I have done everything possible. The led light on the WM300 2.4g tx rf v1 does not light up at all. So I can't pair up the devices. I have enclosed a photo of my now defunct receiver (does anyone have a spare for sale)? My question is, I have noticed that there are identical looking receivers for the p2. Identical in every way. Would one of these work on my p1 ? Thanks.
