Question xbox 360 HDD replacement/upgrade?

[markc1999]

I cant seem to find a way to upgrade my old 360's hdd to a, say, 500gb-1TB version myself. I can only find one for very specific hdds. Is there no general way to do this even now? Was the firmware issue never solved for do-it-yourself ers?
Edit: using different language i found one up to a specific 500gb, tho i think thats slim only. I would really like to use a 1TB tho
