I experienced a power failure and after the camera came back up, I could not get a picture. After much analysis I suspect the the configuration partition (mtdblock8) was corrupted. This a a quess, but if I am right, is there a procedure to restore the nand to “factory”? Any other thoughts?
Search the support section (link at the top of the page) for Factory Reset. If that doesn’t work, you can flash the firmware (again, search the support section).
