My LB2 controller shows RC firmware version N/A. I tried to update it with inspire 1 remote control firmware, I  think i messed up the firmware. Can anyone tell me how I reset the remote controller for LB2 ?

Hello!
Could you please re-upgrade your LB2 with the LB2 firmware? About the upgrade procedures, please refer to P32 of the User Manual at http://dl.djicdn.com/downloads/l ... _Manual_en_V1.2.pdf

Wait for your feedback.
Thanks!
