Yesterday I replaced my damaged ribbon cable with the new one. Finally I got my video fee back and today I made few flights around. I have noticed some purple lines while flying and they were also recorded on my video. So I clicked on camera settings, and tried camera factory reset. After that I have no video fee, no signal notice ... Now gumball goes limp after it does his spins. So there was no crash between last flying and signal lost. Any help or suggestions? Did I erased firmware? Controller reports no error. Gimble status is normal. Its says I have latest firmware. I installed Dji GO on other phone so I could tried with a fresh copy - still nothing.
