After trying out a different S6 camera firmware, my quad started to have issues connecting and staying connected and to start a fresh again I thought it be a good idea to update a fresh.
And as I not wrote anything before about doing a update and it may? help others having strange issues with there Wingsland S6.
What you need:-
Usb cable from pc to micro usb type which plugs in the S6 next to the sd card.
A Windows pc
First follow instructions in the Wingsland S6 updater util link above from what you will also get the file from at the bottom of the page.
Now after about a few mins the updater will be done and S6 will have stopped flashing, so power off S6 by removing the usb lead.
Then run Wingsland S6 app on phone and it will tell you of a firmware update to install the lastest firmware version (because version in the Wingsland updater is a older one), so do this next.
Then download the camera firmware file above and unzip it and place the Wingsland.bin file from it onto the SD card.
Then put battery in S6 and power on and wait for a few mins until its finnished installing the camera firmware.
Then power off the S6 and take out the SD and delete the Wingsland.bin file from sd card and put it back in the craft.
Then once S6 powered back on , go to the camera settings on the app on phone and reset the camera settings.
I would also reformat the SD to cover all bases (Make sure you saved your videos first)
Hopefully all this might have helped.
Although doing this still will not cure the fact that at times when I start app there is no video and have to exit app and back in a few times. This only seems to happen on my iphone6 and iphone 5, the app on android dont seem to have this issue and so assume this is another bug.
Happy flying!
