Hacking dstwo not working after system upgrade

[seanhite]

i did a system upgrade on my old dsi last night. but now it will not read the card. am i screwed or can it be fixed?

was the dstwo, updated to the lasted FW 1st

if not
you will need a system that can use to card to update the card

it was not. i do have a ds xl that still works. though i have not updated any firmware on it. not sure if i really remember how.

First rule of game system hacking: Don't do official updates without making sure it's okay first.

Anyways stick the latest firmware+EoS update on it and hope that works.
