Few days ago I've tried to update my Nexus 7 2012 model, from 4.2.2 operating system to 4.4. After few minutes, after reboot, on the screen shows the Android sign with an error mesage : No Command
The bigger problem is that in my Device Manager, my computer does not show the tablet, not even as an unknown device. This is how my Device Manger it is looks like:
I have tried all the internet tutorials, SDK Manager Drivers, PdaNet Drivers .. Nexus Toolkit .. and no results. My computer does not recognize the tablet, When i run abd devices .. returns nothing.
As i can't go inside, i'm not sure if the USB Debugging mode is activated or deactivated.
Please help me !!! I really don't know what to do
PS: When i'm trying to install the driver manually it says; Android ADB Interface - This device cannot start. (Code 10)
