Cuando lo intento con el phoenix se reinicia la tablet y luego me sale este mensaje:
- There is no device to be upgraded!
Le doy a aceptar y me sale este otro:
1 - Long press the power key at least 10 seconds to power off the device.
2 - Press one key except the power key and do not release.
3 - Connect the device to the pc computer.
4 - Click power key for about 10 times.
5 - Release all key pressed and device will be auto upgraded.
6 - If device do not enter upgrade process, try repeating the steps 1 to 6.
Y ya aqui me pierdo, intento seguir las indicaciones pero nunca me actualiza.
