My vortex 150 and mojo 230 accept flash. Sometimes it will start, but will never complete a flash. Been through all the discussions. Ive owned more than 1/2 dozen vortex/mojos and know about drivers and cables. I have zero issues with any other brand of FC connecting to Betaflight, flashing, etc. Ive been through all the bootloader steps and processes with no benefit. Atleast 20 times. The suggestions previously given on FPVlab for stuff like this, by immersionrc people, dont work anymore. The links dont work and all the support has been stripped off the site. What gives? I sent an e-mail and got no response. What other solution is there besides to stop buying immersionrc quads? What do I do with the ones I have now? Ive tried swapping out synergy boards, etc etc etc etc etc etc etc...........
