I meant u16 compass sensor of course.... I bought a broken i5 and found the compass sensor being half melted away... When I was heating it up with a heat-gun, I was stupid to put my tool to soon and I popped off the U16 chip, but also the little board underneath it :-( I was shocked about my dum action, but I will have to live and deal with it. I am thinking to jumper all the contacts from the little sub board after soldering a new U16 compass sensor. I ordered a bare logic board to see how the copper tracks go underneath the sub board and to know which side of the filters I have to solder the jumper wire at.
