hi guys while i'm waiting for my iphone 7 to arrive, my iphone 6 plus stopped working, apparently plugging in my headphone jack caused some sort of shorting the device, and now it won't boot up and is in recovery mode with error 40 on itune, can't restore can't restart nothing. i went to bestbuy and they ran the diagnostic and said there is a charge problem, when they plugged in their voltage regulating machine it said the current is not fluctuating like it usually does when its charging. so therefore i'm narrowing down my issue to possible battery or the charging port. possible solution i been doing alot of research and i keep finding that people having error 40 and they are fixing this by heating up the memory chip up to 330c for 30 seconds. however i'm not sure if this solution is related to mine. but will be adding it on to my list of solution if replacing the battery and lighting port doesn't fix. if you guys can give me some feedback on this i would greatly appreciate it. thanks in advance.
