Hi I successfully reprogrammed my vision + wifi module but I still cannot get video feed to the dji app , i also tried  pinging the 3 addresses and can only get a reply from 192.168.1.2 .

192.168.1.10 and 192.168.2.1 i get  no reply.

I have checked the cables rebound the extender  , i still get telemetry from the app but no feed . could it mean that my top board is toast or maybe try another reprogram incase it got written to a bad part of the nand? any suggestions appreciated.

Decided to try reflashing  the board again and now i get the following error , gona check the contacts of the solder and try again.

Yeah not all flashes are successful - there's only about an 80-90% chance it be successful and then work.  And even if it does work, it could fail after a few months again.  These boards are from five years ago and not designed to last forever.  Good luck
