iPhone 6s stuck on apple logo after battery replacement
Hello, today I faced with a problem I never had before on an iPhone 6s. At first I was changing the lcd and everything was ok. Then my customer asked for a battery replacement for this phone. After installation of a new original battery phone got stuck on Apple logo. I tried to put back the old battery, but it also gets stuck... I am trying iTunes restore with dfu mode, but it shows me error (9). Does anyone got the same problem? Is there a problem in motherboard?
Is this a good question?
