Older Kobo won't turn on

I have an old Kobo. Last weekend I connected to kobo desktop for the first time in a few months. It updated the software, now it won't turn on at all. All it says is "updating the software on your ereader" I tried leaving it on for awhile to update (a few hours), didn't help. I tried going to a free wifi area to update, didn't help. I tried the paperclip in the back, didn't help.
Any other ideas? Or do I need to go shopping?
