I'm not new to the 505, and even offered advice before on how to make sure your bookmarks stay saved:

But my problem is, I just upgraded to the "new" firmware released for the 505 a few months back (yeah, I'm late). But now, my reader can no longer retain any bookmarks made if I shut the device off and power it back on: all gone.
I can make the bookmarks, but if I turn the thing off, they'll be lost when I turn it back on. This is so annoying! Someone please help.
