To continue from what Kovid Goyal said, I would suggest taking a backup of your Glo HD's internal µSD card. You can try copying it back to a new µSd card and possibly doing a factory reset. If that doesn't help, you can request a copy of the image for the internal µSD card. To request a copy of the image, please post in the
Glo HD - SD Image available yet? thread. For a guide to creating and restoring an image, see the
Memory Upgrade Mod Guide (With Pictures) thread.
