I eventually got it right but my action is also very high,like 6mm at the 12th fret.
I would not consider just raising the action 'getting it right' ?
Do yourself a favor and do/get a fret job. This will entail while the strings are off and the truss rod relaxed:
- all the frets seat properly
- there are no low frets and no high frets, just a cylindrical (or conical) face over the fret tops
- the frets are all equal curvature without flat spots
- the frets are nice and shiny again.
Then, if the truss rod is set correctly, the action should be able to get back to between 1 (very low) and 2.5mm (rather high) depending on taste.
