I bought a logic board that was locked to a net work and jailbroken. I got it network unlocked and restored it.

It gets coverage in large towns but not anywhere else. I have checked connection no.7 and it is perfect also both gold prongs are touching the Bessel. The only thing I can see is on the back of the logic board, directly under the number 7 connector there should be a little gold round thing, and that is missing.

Any help would be greatly appreciated.

Post an image of your board with your question. This will let us see what you see in respect to "the gold round thing"



I am not sure how to load an image, I tried and there is just a number.

The round gold thing over the first screw hole bottom right. This is missing from my board.

Maureen Kelly, "The round gold thing over the first screw hole bottom right" is reference designator J5_RF and it is your cellular antenna connector. You kind off need that for your phone to function properly. It is a Murata MM8130-2600 and check the datasheet for the exact part on here. Please be aware that this part is very small, it does need soldering to be replaced. You will need some great skills and good tools to replace it. Hope this helps, good luck.
