Thanx to ToySoft for directing me to the right place... and to the necessary reboot of my PC, after the drivers did not install the first few times around, plus a bit of exercising of my little grey cells...
After a bit of wrangling - I succeeded... This really does work, unlike the previous versions I tried long, long ago, when I was stuck in a similar fashion...
So, I recovered my F500HD, thanx also to somebody saying to untick the "LAN/Network" box in the Flasher GUI, i.e. to have the cable plugged in (possibly to detect the box) but not to use the network to flash it, I suppose...
The flashing is done by a mini USB cable, I presume and it is slow - but it worked!!! BRAVO, whomever wrote that! I is 'appy clappy chappy now, having my special box back!
One must install the drivers first, then the flasher starts, and if it can't connect - restart your PC, unplug everything USB-wise, try again. It worked in my case.
The trick was to retry: direct the reinstallation of drivers by choosing the C partition, then it found the drivers and then it all worked as described above!
I managed to flash my F500HD with PurE2 from this cool forum, then I deleted a few things (Blindscan, Cable etc.) and mounted my USB stick.
I restarted and I INSTALLED THE OPEN MULTI BOOT (OMB) PLUGIN from the feeds. I.e. IT IS POSSIBLE to have OMB installed!!!
Now, let's see if I can remember how to install images in the USB stick via OMB...
