If your Tegra 3 prototype is not responding to touch, you can try to reboot it using adb from a shell window.:
> adb reboot
If adb is not responding either, then remove the backplate, and find the reset button below the camera flash.
To flash a new system image, follow these steps:
flashos.batif you are running Windows, or
flashos.shif you are running Linux.
Some of the FCam examples will save data to
/data/fcam. This directory does not exist by default. This is a good time to create it.
Run a console and type:
> adb shell mkdir /data/fcam
Also, by default the device screen will go to sleep after 1 minute. This could be very inconvenient. Tap on the clock, select the Settings icon, choose the Settings > Display > Sleep option and change the default timeout time to 30 minutes.
There two possible reasons for this. Either the tablet is not in recovery mode, or there is a problem with the recovery mode USB drivers.
To check that the device is in recovery mode, make sure you have followed all the steps outlined above. The tablet screen should remain blank in recovery mode. If you see the tablet booting, then it is not in recovery mode. After you have successfully put the system into recovery mode, try flashing the device. Make sure the USB cable is solidly connected to the computer and the tablet. If you still receive the same error, watch for Windows notifications about missing drivers.
To be sure, you can launch the Device Manager. Under Universal Serial Bus Controllers, you should see one device named "NVIDIA USB Boot-recovery driver for Mobile." If you don’t find this device, there is a driver problem. Check the Device Manager for an unrecognized device (the one with an exclamation point next to it). The easiest way to fix this is to disconnect and reconnect the USB cable to the computer while the Device Manager is opened. Then, update the driver to the one included in the system image package under
