Hi everyone... I normally don't ask for help but just say goodbye to things that get ruined, but I want my tablet to work again so, here's the problem: The SDcard (internal) appears as unmounted, it won't recognize an external SD Card and when I go into Settings->Storage, it crashes. This is what I did: Connected the Tablet (without external SD card) to the computer and copied an .apk file to the tablet. I was stupid enough, though, to delete a folder called "external_sd", and I think that was the beginning of my problem, although... I installed the .apk file on the tablet and everything worked fine. Inserted the external SD card and the tablet didn't read it at all The previously-mentioned installed app now crashes when I try to open it, so I uninstalled it. Restarted tablet with external SD card inside Attempted to re-install the .apk from the internal SD card, but it showed as unreadable The external SD is still unreadable and the internal one doesn't get any better. Tablet specs: Coby Kyros MID7033, ICS (4.0.3) I honestly don't know what to do... Any help is greatly appreciated. Let me know if you need more information.
