SKY 706 firmware upgrade
I tried to upgrade the firmware from SKY706 to SKY706V as per instructions in the user manual.
However, the SKY706 application just hanged and now the TX doesn't work anymore :(
Any clues on how to fix this?
Thanks for your reply.
I managed to fix it now by installing the original firmware again.
Here is a summary of the problem and it's solution.
The SKY706 application crashed whilst trying to update the firmware from SKY706 to SKY706V.
After that, the TX stopped working. It would link to the application and bind to the RX, but the sticks didn't send any signals to the RX or to the computer simulator through the cable.
Tried the firmware upgrade several times again, but it didn't work either.
In the application included in the CD that comes with the plane (Folder SKY706_V1), there is a folder named "siuse".
Within that folder there is another folder named "Upgrade", and inside this folder another one named "DeviceFile".
There you can find a file named "SKY706 D5-S1.res~vdrc".
I renamed that file to match the extension of the firmware files, i.e. to "SKY706 D5-S1.vdrc".
Then, I used the SKY706_V1.exe application to upload that file as the firmware to upgrade the TX.
It worked in this case, and the TX was fixed.
After that, I tried running the firmware upgrade again (to upgrade to SKY706V) and this time it worked.
The upgrade normally proceeds correctly, but sometimes the computer program can lockup or fail, causing the update to fail.
Good news that you are now back to operating condition
