Debes ejecutar el proceso de recovery que puedes encontrar en este hilo, como ya te han explicado tan solo ten en cuenta:
- Ejecuta la ultima version de la USB Image tool
- Prueba con varias MicroSD en mi caso fue la tercera
Por si acaso aqui lo tienes en ingles con mucho detalle, si no lo encuentras o te hace falta lo traducimos
If your Novo 8 Tablet will not turn on but the trackball lights up and the tablet vibrates each time you press the power button, it may be required to carry out the procedure below.
USB Image Tool Firmware Update Procedure
1. Download the Novo 8 Tools zip file which is specifically for firmware 20110719:
http://www.ainol.com/rar/novo8tools20110719.zip
- Please note that each new firmware will have its own tools file.
2. Download the following USB Image Tool:

3. Using a Micro SD Card (preferably 1-4GB) & Card reader, connect the card reader with MicroSD Card inserted to a computer.
4. Back up any files already on the Micro SD Card first, once that is done format the card whilst making sure you select FAT 32.
5. Launch USB Image Tool and select RESTORE then browse for the file: novo-8-update.img (from the novo tools package)
This process will create an image on the Micro SD Card which will then be displayed in My Computer as an empty disk, this is correct. Insert the Micro SD Card into the Novo 8 tablet whilst turned off (please make sure there is at least 20% battery life).
To begin flashing with the latest firmware, press and hold the POWER & VOL+ buttons together for approximately 25-30 seconds, once the screen displays recover release buttons.
After the firmware updates successfully, please turn off the Novo 8 and remove the Micro SD Card.
Additional Notes
The firmware provided by Ainol is currently set to Chinese language as default and will
require changing to your native language. This is simply done by going to settings menu and selecting the language menu which has the [A] icon.
