Hello, I have tried to reinstall windows on my omni 10 5600US tablet, after reinstalling windows the home/power/volume buttons didn't work. The camera wasn't recognized as well. The windows works but i just cant lock it or anything like that. I didn't have the original recovery SD card or whatever came with it. The fresh windows 8.1 x32 literally screwed it and I didn't know it would be that much of a issue. Is there anything I can do to make it the windows "tablet suitable" ? The touch works but the buttons are not responding..
