Completely wiping all contents and storage in SmartQ T10 tablet. No Recovery, no CWM, no ADB I wanna hard reset my SmartQ T10 so memory and internal storage become fully deleted, but my device does not have such option in Settings, nor there is ClockWorkMod Recovery released for it.
I did try:
- Restore firmware.
- Boot pressing volume up, volume down and both (goes to firmware restore).
- ADB: adb reboot recovery (goes to firmware restore too).
- Research at http://www.hard-reset.com/ (no SmartQ models there).
so I was wondering if it exists any generic non-platform-specific trick.
For a real safe and complete wipe, you might want to take a look at Nuke my Device.

If you're just after a factory-reset, this can be find in Settings. But then you shouldn't forget about your other storage (SDcards – internal as well as external ­– are usually not dealt with by a factory-reset, though some ROMs do so).
