Hello and good day scorpiopaulius. I am sorry for the trouble and to know what is happening to your DJI Phantom 4. Since there was a crash that happened and then this issue is happening on the said drone. I would recommend you contact our DJI support team to start up a ticket for the said drone at https://www.dji.com/support?site=brandsite&from=nav . There might be an issue internally that is why you are experiencing this issue as of the moment. We have the professional team who would do their best to analyze and fix the said drone. Thank for your understanding and for your support.

Perhaps its completing tests and causes you have a ripped cable its failing them and then finally gives up and shuts down, just guessing mind....

Yep, I agree, that's a very good guess.

Guesses are good... hahaha But resolves very little.

Perhaps try reinstalling the firmware, or update the app.  

My guess is as good as any. Chuckles

I found out that inside one of flat cables was cut in half... Lucky drone was flying but after changing flat cable - turns off good
