How to repair the "blue inductor coil"?

After teardown the blue inductor coil placed on the logic board got broken or damaged, there is no blue inductor coil at the moment.

I asked my friend and he has a contact who sells the blue inductor coil but I do not know how to put it back on the logic board.

I would like to know if any of you know how to repair it, is there any guides on ifixit.com? a video? anything?

Thanks so much.

No guide can teach you the soldering skills required to replace that or supply you with the necessary tools. Click here for a person that will have the part, skill and proper tools.

It is not that hard. There is no need to replace the coil just make a little jumper with the soldering iron.

The answer to your questions, how to fix the blue inductor coil causing a signal problem, the solution is easy we have repaired many with a 100% success rate. If you look at the signal antenna which you plug the cable into, simply run a wire from the left side bridge it to the right side point on the blue coil and follow it all the way to the furthest (right) component on the top left side. This will act as a 'bypass route' and your signal will start to work again.

All it takes is a bit of micro -soldering knowledge and some 0.1mm wire and basing soldering equipment. This will fix your problem guaranteed, providing it was the missing blue coil that caused your signal issue in the first place.

Kind regards,
