Chosen Solution
i had a iphone 6 come in that was on the connect to itunes logo, customer said they tried updating over wifi and it failed. i found a short on vcc main so i wired my dc psu into the line and injected voltage. found the board getting hot near c5202rf so i removed it, still short, and still getting hot in the same exact spot. so i removed the other caps on vcc main in that spot (mind you i did all of this with micro tweezers so no hot air was used at this point). still getting hot in same spot, so i open zxw and see the wifi chip has vcc main lines in the same exact spot. so i decided to remove the wifi module. that relieved the short, so i probed on the actual module itself and found it to be an internal short to the wifi module. great, so with it removed i was able to restore and get the phone booted. i then ordered a replacement module from microsolderingsupply.com and when it came in i replaced it. no short anymore, but now im getting no wifi. no components are missing around the module and after checking all the components around the module against known good board i cant see any difference between the 2. and i already checked the antenna up top. anyone have any ideas of what i can check next?
It appears you did all the right steps. I would suspect that the WLAN is not fully/properly soldered in place. If one ball/pad isn’t connected properly then it could be causing your issues.
