After updating to a new firmware I got 2 problems.
First, my battery was dead 2 days later though I didn't turn my 505 reader on.
Secondly, reader doesn't see the SD card. Computer sees it, sony library software sees it, reader doesn't.
Anything could be done? Is any way to go to a previous firmware? Can someone provide a link to a previous firmware?
Thank you!
