My smallest task ever - iPhone 4S Logic Board Replacement
The iPhone went swimming in the lake for awhile - resuscitation efforts failed. After a good cleaning, the phone worked but the WiFi / Bluetooth chip was dead.
The disassembly and reassembly went well. IFIXIT instructions and illustrations are very good.
Happy to know that IFIXIT has the parts and advice to go with it.
Job well done to all at IFIXIT.
