A few years back the office got flooded and my N900, which was in a drawer ended up in silt and water.

I'd presumed it totally dead but today I happened to spot it, connected a usb charger and switched it on and it booted up to the lock code. Unfortunately although the touchscreen seems to vibrate to touches, it doesn't register the numbers.

So next I flashed an older version of Maemo on which boots to the first settings screen. Again it vibrates but doesn't register.

I would guess there's something haywire with the touch screen digitizer but before I trawl ebay for a new one, is there a way of getting past the settings screen and launching the screen calibration tool or a terminal?

It's the second digitizer I've had in that phone. Neither were terribly good and I was forever recalibrating the screen when it was 'working' before the flood.

I've had a quick disassembly, cleared out the silt but didn't spot anything terribly out of place or corroded.
