resently i have had a few PS2's returned with failure "won't play backups". When inserting a backup disc the ps2 sees it as a valid disc but will not play it. Same issue with firmware 34v2 ! so it is not possible to reflash firmware. tried an old cd with firmware 1.8, this one boot's but i when selecting flash, it just says "done" right away. Installing bootmanager from v1.8 to a memcard seems to work, but PS2 doesnt boot from memcard so no luck there.
Any one got a solution ? (other than replacing the chip :-/ )
