Reasnow app does not work unless I'm using the latest firmware, so I upgraded to 5.5.6. Now my Reasnow doesn't work. Beeps four times with no light. Reset device as mentioned in Problem and Solution, but this does not fix the issue. Tried reverting to firmware 5.4.8 and my Reasnow works, but I can not use the app because the app is forcing me to use the latest firmware, which doesn't work.
