Bricked X4R-SB?

Post by rasqba »

Hi,

today I tried updating (downgrading?) an EU-LBT X4R-SB receiver, to non-eu firmware. I followed this method: http://www.dronetrest.com/t/how-to-u...4r-x4r-sb/1667
However, around halfway through programming, receiver LEDs turned off, Taranis showed a "Firmware update error", and the receiver seems to be bricked. No leds light up when I apply it 5v, when I try to program it, the Taranis immediately shows the same error, and no LEDs light up.
I thought maybe the voltage regulator fried, but it works fine (3.3v at the output).
Is there anything I can do to revive the receiver?
Also, what could have been the cause of the programming error?
Have a nice day :)
