Has anyone succeeded in opening the case of WonderMedia tablet? I have to do it in order to fix something. As there are no visible screws at all, I guess I just have break into it...? For more info, please see http://www.androidtablets.net/forum/wondermedia-based/15818-brand-new-owner-8650-trouble.html There are also a link to some pics I just took. Any hints and help appreciated.
