Can you @flyride tell us exactly what files to copy? That information is in the thread you quoted. My first response explained three different options to you. If you pick the third option (1.03b loader, DS3615xs and DSM 6.2.2 without Intel NIC) you will probably need the drivers in extra.lzma. @zzgus just posted the link, you can follow that thread.

I don't know if you can assume anything, and you need to know how your server works before you do anything else. ICH10R (Intel chipset) connected ports may have a simple BIOS-accessible RAID 0/1 option which you should turn "off." However, some server motherboards can have an embedded third-party RAID controller such as an LSI/MegaRAID which would not work well unless flashed to "IT" mode as previously described. Embedded controllers may not be flashable so ports connected to those controllers would not be good candidates for XPEnology.

Alright, after replacing the currently used usb stick by another one it works fine. Obviously Hardware fault.
