Hello, Thanks for your question. The La forge v2 has been updated a few times since the manual release with the biggest update being the replacement of the clickable scroll wheel with 3 buttons. the 3 buttons work fairly simply with the upper most button operating as a up the middle acting as enter/ select and the lower as down. if you are looking to perform a firmware update that would need a FTDI connection in conjunction with the app and drivers from UBAD which can be found here, http://www.laforgefpv.com/firmware
