Just for info - wrote to yuneec to try and get the recovery file - no response.
2. All files downloaded from the website are UPDATE files which means the base layer that boots the device has to be loaded and that is what I am looking for i.e. The file/ bootloader that is put into a virgin chip at the factory . This will be loaded via the stem defuse utility.
3. Most respondents advise various methods but I think my problem definition was poorly stated .
4. The problem is that connection to the PC via USB does not work at all to the gui and when the H is powered on as soon as power switch released it powers off . Some posted that without the battery power is supplied by USB connector. On my unit this does not work . I have buzzed out the cable from the PC end to the control board on to of the unit and all connections are 100%.
Why yuneec can not put their bootloader / recovery file on the web site is a real mystery .
