I bricked 2 x4r-sb’s!
I read the responses and your Howto.
I followed it to the letter.
The first x4r is from China and wouldn’t bind. So I thought I needed to update. I did.
The progressbar started, red and green lights flickered, then it ended with the error “defice refused the update” I downloaded this firmware from FrSky:
X4RSP_EU_V21_build170322.hex.frk
Which should be the right one.
When I power up the receiver it’s completely dead. If I try to update it responds: no response, can’t update.
I thought I might have bricked it because I didn’t fully attach the connector to the Taranis. I tried again with my “old” receiver (chopped of the antenna’s, bought it in NL, never messed with the firmware). It bricked the same way. So I have 2 receivers bricked.
