A couple of years ago I helped a friend to fix a ASD. I found that the Integrated Circuit board carrying the ports (especially the USB ports) was a tiny bit dislocated inwards in the ASD. The effect of that was that USB connectors did not connect. When I modified the USB connector so that it could be shoved a bit deeper into the ports, everything started to work.

Well, it is not obvious how to do this. I have no iOpener, but a heat cushion for remedy hurting muscles and sometimes a backpain. It is filled with grain of some kind and it is to be heated in a microwave oven for about 3 minutes. After that I enveloped this cushion round the phone and brewed myself a cup of tea. After ten miutes the phone was warm (almost hot) and I was able to press the tip of a small (very small) knife above the charging port into the connection between the phone body and the backplate. A very small opening emerged slowly (this is the critical point in this process) and I was able to start using the iFixit opening picks. It became obvious to me that the opening picks are too blunt to achive this with them. But after starting carefully with the (very small and very sharp) knife, everything went straight forward. Thou I had to give the phone a second heatpush with my heat cushion before the backplate came loose.

I have found the following solution for an TBD displaying erratically : the USB male connector on the USB cable seems not able to go deep enough in the female connector in the chassi. I have cut away about 1 mm of the male connectors plastic cover thus making the metal part 1 mm longer. When putting it into the Female connector it goes deeper and connects better. I have done this with three TBD:s and they all became “living” TBD:s without problems.

I have had the same issue with USB ports not working on the ATD. My solution has been to cut away about 1 mm of the plastic cover on the USB cable. That means that the male end of the USB cable connector will become 1 mm longer. Connecting a thus modified cable to the ATD solves my problem. The solution indicates that the female USB connectors in the ATD is mounted too deep into the ATD.
