I just solved how to fix this error message while updating firmware(i was updating to akira). It has only been referenced once online and with no solution. ( http://forum.freeflysystems.com/ind...oth-please-reboot-device-and-update-usi.3090/ ) "Failed to update firmware! If device supports WIFI and bluetooth please reboot device and update using bluetooth" This updated failed on 2 androids and 2 mac computers. What I did to solve the issue after lengthy emails back and forth with Chris was to do an unbrick firmware update. So i guess if you have this issue get a hold of them and try to get the instructions for an unbrick+jumper+firmware update This ended up working, the firmware update progress bar was moving for the first time and now everything works.
