Iphone 7 Flashing apple logo
Hi,
I have an Iphone 7plus (7 months old) with the current update.
For about 24 hours i noticed the phone charging chime activating even when phone was not connected to anything.
Then last night whilst using phone my screen went blank the apple logo appeared and starting alternating between the blank screen and logo being desplayed.
I pressed the sleep button and volume down button and the connect to ITunes screen came up.
I connected phone to macbook and opened ITunes and phone went into recovery mode and I clicked on update phone without losing content..
My phone serial number appeared, so i know itunes was able to communicate with phone but when it went into update the 4013 error code appeared telling me it could not carry out update.
I then attempted to restore phone (reluctantly due to I use my phone for BUSINESS USE I will lose a **** of information..I have backed up the phone a month ago but since then I have added a lot into the phone)
The restore was unsuccessful and came up with the same error code.
Do you have any advise before taking it to an apple store?
And is it possible to retrieve information off phone in this situation?
GGRRRHH!!!
iPhone 7 Plus, iOS 10.3.1
