Jrty thanks for the answer! :)
But, along the way, the board in your drawing never looks like mine ....
So, I strongly suspect that we are simply talking about different devices !!! : blink:
I have an iPhone 2G, apparently you have an iPhone 3G: wacko:
Hence my lack of understanding, and the lack of elements similar to your filter ....
The main board, upon closer inspection, was assembled from 2 boards connected by a connector. So two more “internal” planes of the board were drawn:
In general, I did not find any visible defects and did not find a ceramic filter either - I took it apart, examined it from all sides, cleaned and reassembled it.
There is nothing particularly complicated in this procedure, you just need to choose the right tool and do everything carefully and slowly!
The device works, Wi-Fi is still out! : wallbash:
But the problem clearly has hardware roots, as cooling really helps until the machine heats up again!
Maybe, after all, does anyone know where the root of evil is in the iPhone 2G ???
