Chosen Solution

The question is how do you make the jumper, you have to use soldering iron but what part is the one you have to weld? the whole “path”? just a part of it? I attach a photo asking what part is the one to weld, the area in the red circle or the blue path. If there is a guide on how to do that would be awesome! Thanks. -K

krixx, in cases like the one shown in your image, I would suggest a circuit writer pen.

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, Ideal mobiles
