Thank you Maris. Well i was able to recover it yesterday. I will put here the
error it gave me than the v.build solution. I have posted this in QGIS
forum:

Then i runed v.rebuild:

So apparently the layer is back again and working, for now :-). It seems the
file (coor) has a storing limit capacity that was surpassed (makes some
sense cause it happened just when i was adding a vector point)? By the way i
notice one think. When trying to open the recovered grass vector layer it
seems he automatically devided it in two (one for the lines and one for the
points). Well the problem is how am i gona edit a line/point layer (to solve
those flat top surfaces)? I could use lines too but the effects would be
similar (flat surfaces but smaller). Im afraid i will have to try your
suggestion Sab (v.digit). I will see it tomorrow morning. For now thank you.
I think Hamish mentioned this procedure:
First digitize a new point vector map of the peaks, with elevation in an
attrib. column. Then convert the points to raster, using the elevation
attribute as raster value. Now merge this new "point" raster (it should
have values of zero everywhere except the cells at mountain peaks) with
your rasterized contours map. And finally recreate the DEM from this
combined contour+peaks raster.

So aparently im stuck to how iam i gona be able to make a point/line layer.
