Hi, I have a Ricatech tablet, with Rockchip 2918 CPU, that doesn't start anymore. The tablet doesn't come further as the startup window of Android. I Tried to reset and update the firmware of the tablet, but so far without any result. When I connect the tablet to the pc it is recognized as a virtual drive but I can't acces these drives. I reinstalled the drivers, tried different ports (different PC's) without result. The PC recognizes that the tablet is connected (with name), but furthermore I can't acces it by PC. Does anyone know if it's possible to flash this tablet through an bootable USB Stick or SDcard? How can I do that? Thanks.
