Everytime you boot your olimex it spews out tons of information. It tells you what OS is booting, what drivers are being installed, what services are starting up. Also eventually the UM software starts running as well including the recovery programs and it spews out stuff as well to the console. Every. Time. You. Boot.
Until now that information just goes to those 3 pins and is never observed.
So you leave the SD card in the olimex and power up and look at all that info you have been missing all this time. That's the first step. Read it all - look for error messages - try to see where things go badly (usually near the end). Post the result and let me look at it.

That's fantastic. I suspect this *older* version of the firmware recovery procedure formats the partitions! I will add this to my web page on unbricking for UM3 users!
