Worked like a charme. Can use my headphones again. Thanks for the comments as I skipped the step with the front facing camera which is totally unnessary! Should be deleted!

Argh, seems that my connector was loose. I pulled the cable up and the ring on the connector came off. Here a picture. Hope you can see it.

I did this repair several times. Never happend to me. Any idea if I can rescue the connector or should I buy a new FPC Connector, because I think the rest of the connector is still on the board? Anyone did a resolder with success?

Ok, worked! Great thanks! I first tried the usual stuff then I tried the hair dryer method which worked with another i4s, but not with this one.

I didn't have Kapton tape, so I used oven paper and aluminium paper on top of it to cover the mainboard around the chip. Also I didn't have a reflow station and used a hot air gun instead which has adjustable temperature control with display. I took the smallest cap which was a bit larger than the chip. Then reflowed it with the given timings and temperature reduction. Works and I hope for ever.

Thanks. Ok I'm trying it right now. For security I put oven paper and on top of that aluminium paper over the areas which should not get to hot. I preflowed them to see if they stand the temperature. Seems to work. I report back

Is there an alternative for Kapton Tape? Like some layers oven paper and aluminium paper over it?
