I have a R4 and did a firmware upgrade from 3.01.06 to 3.01.20, it didnt work and my R4 is unresponsive, no screen, no main menu, just power button glowing every 10 seconds. I read you must down grade from 3.01.06 to 3.01.05 then upgrade to 3.01.20. Well I cannot communicate through USB as it seems all communication doesnt work, zigbee or USB, any suggestion?
