After using the freezer method and hairdryer method, the WiFi began working for briefly. I disassembled my iPhone, removed mother board, and used aluminium foil to protect it. I left only the WiFi chip unprotected. I used a heat-gun at 300 degrees to heat up the chip for 5 to 10 seconds and left it to cool down. I reassembled the iPhone and voila, it works. |
