So that didnt work.
But I went back and did as you said, trying to reheat the wifi module this time. I removed the sticker and heated it with a soldering iron and some aluminum foil. Not sure how you guys manage to get it 300C, but i heated it enough for it to feel very hot. Then I reattached the black sticker and put the Iphone back together and Yes it worked! But I must say, it feels just like the fix that the hairdryer does too, so Im not surprise if it stops working after awhile.
If you guys manage to get it to 300C, I guess it takes a lot longer for it to cool down, so it seems to be solved, but when its actually just temporary. Who knows?
Please tell me if Im wrong, just thinking out loud.
