Not reading a media card limits you to using Updater.exe only. Try flashing just the Oregon 6x0's boot.bin as an RGN file. Open the O6x0 firmware in RGN_Tool and uncheck the second section. Save the file named only as OUT.rgn:

Flash OUT.rgn in preboot.
If it works the ramloader in virtual region 12 will be updated and device should boot to a screen showing "System Software Missing" or freeze on the logo splash screen/bootloop. We may be able to recover if any of that happens.
If nothing changes i'm out of suggestions other than to strip it for useable/saleable parts, the PCB is only good for waste if nothing can be flashed to regions.

I made and flashed OUT.rgn. UPDATER.exe after flashing, writes OK. Defines it as Oregon 600 (Unit id 0). Oregon freezes on the FIRMWARE LOADING splash screen... After reconnecting, the Garmin logo again. The updater defines it as Oregon 750 (Unit id 0).
