I have a Nextbook Ares 8 tablet that is stuck in boot mode. I tried to restart the boot loader and got the message: E:No valid

My tablet is stuck at the logo screen and will not boot up.

NOTE: If the device is still under warranty, before doing anything to it, please consider contacting the manufacturer about repairs and replacements.

Have you tried pulling the battery and leaving it off for about 5 minutes and then placing it back in to see if the problem is resolved? (Yes I know the batteries are a pain to remove on tablets).

You can also try turning it off and seeing if you can load it in "Safe Mode" to see if it loads completely. If it does, then you probably have an app or update to an app on the device that is causing your issue. You would need to locate and remove said app/update.

As a last resort, if nothing else works, you may need to do a "Hard Reset" on the tablet. However doing this will wipe the device.

To get into "Safe Mode" please do the following.

1. First turn off the tablet.

2. Next press and hold "Power" until you see the manufacturers logo on the screen, then release the power button.

3. "Quickly" press "Volume Down" and hold it for few seconds until you see the message "Safe mode: ON" or something similar.

4. If you wanted disable it, simply repeat the steps above, and you should see "Safe Mode: OFF" rather than on.


NOTE: Doing this will clear 'all' the data on your tablet, so it is suggested you not choose this option unless you have to, or aren't worried about losing anything on the device.

Be sure you back up any data you want to keep, to a computer or cloud account, before doing the reset.


To "Hard Reset" the tablet...

1. Make sure that the tablet is actually powered off.

2. Remove your SD card, if there is one in the device.

3. Press the "Power" and the "Volume Up" buttons, together, until you see the start-up logo on the screen.

4. Once you can see the logo, release the buttons and allow the device to enter the "System Recovery Mode".

5. Next use "Volume Down" button to get to the "wipe data/factory reset" option When in recovery mode the "Volume Up" and "Volume Down" buttons are how to can navigate and highlight what option you need.

6. Once you have selected the "wipe data/factory reset", press the "Power" button to select that option.

7. On the following screen, repeatedly press the "Volume Down" button until the "Yes - delete all user data" option is what is selected.

8. Then press the "Power" button to hard reset the tablet.

9. If you took your SD card out in step 2, when the device is up and running again, reinsert the SD card.
