At this point I do not know what else to do. How can I get my tablet back to working conditions? Any help will be greatly appreciated, thank you.
I have TWRP v2.2.1 and no rom is installed. I read about ADB being able to push files to my device in order to install a working rom. It turns out that this version of TWRP does not have ADB sideload. I should also note that once I'm in the bootloader and I connect to my pc the volume buttons do not move the menu, it doesn't respond. The computer recognizes that it is connected but it does not install the drivers.
