Most likely still a cable problem or a balky 2nd gear synchro.

If the symptom goes away or lessens as the engine warms up, then its not likely a cable. A cable problem will be relatively constant over temperature where as a synchro issue is usually most noticeable when the engine is cold.

Another way to check the synchro is to slow shift - clutch in and lift off throttle, then wait a moment and let the rev's drop to idle, then shift. If this helps, then its most likely the synchro.
