Chosen Solution
Im in desperate need of advice before I go prying into my phone to try and fix my greyed out and continously searching bluetooth issue. Ive done my research and tried everything from resetting wifi networks to using a hairdryer/freezer to try and get my wifi working but nothing helped. Ive come to the conclusion that my wifi chip must be completely dead and my only option is to replace it. My boyfriend is taking home a heat gun and flux from his school today to try and fix this for me but id like some reassurance before we damage things beyond repairing. First, i have another iphone 6 that had water damage but i dont know if that would have effected the wifi chip on it. Can I remove the chip and put it on the other logic board that doesnt have water damage or do I need a new replacment chip? I already tried switching out logic boards in hopes that the water damaged one just had something to do with the battery and/or cable connecters but the phone wouldnt turn on so i know its logic board itself thats damaged. Next id like to know if the steps im going to take to remove and replace the chips are correct and if not what am I missing. Heat the chip until its ready to lift off. Clean the area with 100% alcohol Apply flux Lay down replacement chip, re heat, and the let cool. Is it that easy? What factors am I not adding in that could make this go wrong? The phone is no longer contracted by a carrier and has no warranty so its basically a brick. I just want to use it on Wi-Fi for apps and picture taking purposes so I really don’t have anything to lose and don’t plan on paying hundreds to get it fixed. any advice is appreciated.
Don´t use a heatgun. If the temperature is to high you will destroy the whole logic board. You should use at least a rework station. Temperature should be around 400°C. And use a new chip. If your heating up the chip to long it´s defective. The silicon the chip is made of can´t resist temperatures over 140°C very long. So you musst be very fast.
So what is the true heat for Removel? I watched that video and to me it’s very amateurish ok for quick fix. I want permanent which is guess is a new chip or an old chip to be re-balled and contacts cleaned.
