Flash Rom again works
Was messing with this and got my 4gb working with a 2gb partition for android so
went ahead and inserted my 16gb, big mistake.
Wp7 would not boot even when I removed the card.
Have none of the devices listed to unlock so last option was flash again.
HD2_Updatable_XBmod_Yuki_v2_native - works fine, sd card is seen again, bit of a pain adding the updates again but at least the card is working.
