well i decided to report this bug on this thread were it should be heard properly.
after experimenting on deffernt patches but i really cant recall which ones caused this problem ,this is what happened to me:
Mentioning i ve never found out any solution about this problem in any forum on the we concerning our device.

As i said after trying out different combinations of patchs in n9qtweak always with direct attention to instructions including the pdf my device once stop recognising any headphones connected to it with the following results:

If i was playing a track on the player and during the song trying to connect my headphones the device dint realise i connected sth to start palying music on it but continuing playin from the loud speaker and the reverse action.

The only way to use any set of headphones was to reboot my device and connecting the headphones after nokia logo was showed.

By doing that proccedure the sound was coming through the headphones but if i wanted to remove them and use the loudspeaker again i had to reboot the device without the headphones plugged in...

Thats all
