Did something wrong there, obviously
Anyway, this is a reply to the post from Seant
To reinstall the WinCE 5 OS on ur unit, i suggest that you download a version that is readily available here and copy that to a micro SD Card formatted to FAT or Fat 32, then try to re-flash the firmware.
Im assuming that you also have a copy of the firmware saved to your hard drive, in which case I suggest that you use that saved copy and write it to a SD card that is formatted as I mentioned above.
Good luck
