I have a 10" Android Tablet which is based on NVIDIA Tegra2 (Ventana) chip (boot image shows something like: GO MOVIL, Conectate Sin Limites). It comes with Android 3.2 and works fine, and I would like to upgrade it to Android 4.0 ICS using the OS image available from NVIDIA.
I can press-and-hold Volume-down key while boot-up to enter fastboot mode, and it displays the following message on screen:
Preparing for entering recovery mode...
I've tried several key combinations but couldn't get into recovery mode. Could somebody please show me some hints?
