RC4GS v3 fail after upgrade.
 

Need help.. i tried to update my rc4gs v3 firmware.. done everything as in all tutorial.. but now my rc4gs v3 just blank white with beeping sound.. any idea why? And how to fix it?

Hi I'm having this issue did you ever find a solution?

Changing software, You loose everything. Start from beginning of taking TX & RX. Rebind TX & RX as manual instructs. Turn off TX. Turn on TX. Most important thing to Recalibrate your ESC do that per ESC manual instructs. Turn off TX & RX to keep it in memory. Turn on system it should be normal use. Good Luck!!

DO you have a video to show how to do this, because I have tried a few times but I don't think I'm doing it right
