After updating my Inspire 1 I could not upgrade the RC. I turned on r/c and Inspire 1. Swiped down on red rectangle on top of screen. It said I needed to update firmware to version v1.3.0.00 I went to DJI page, made sure all bin files were off my usb thumb drive. Downloaded v1.3.0.00 to thumbdrive. plugged it in my rc and turned on rc. (DO NOT DOWNLOAD THE MOST RECENT VERSION. JUST v1.3.0.00, the other firmware will load by itself after) It worked perfectly. Then turned off rc. turned on Inspire 1. Turned on RC. swiped down again on red rectangle, touched red triangle to update controller. It all worked perfectly. Hope this helps.
