Q: Flashing logo loop
Two days ago this started. My iPhone 5 would not turn on no matter it's full charge, it would only show signs of life when plugged into the wall but all it did was flash the apple logo on and off in a continuous loop. I googled this and everything I read suggested putting it in recovery mode and then restoring it or updating it. I did this on my of but every time I attempted it, itunes came up with error code 21. I googled that and did everything it suggested (updating iTunes etc). Still no luck and same error code. I then attempted to try on my desktop Mac but the same thing happened but with error code 2001. It just suggested that my cord was faulty which is definetely not true considering is only a few weeks old and works fine for every operation. I have been without my phone for two days and can't book an appointment at my local Genius Bar for 2 weeks. Please help!
iPhone 5, iOS 9.3.4

Hi
Follow the steps here for error code 2001:
When connecting your iPhone to your computer, check that you are using either a genuine Apple cable or an Apple-certified / MFi cable. If you are already doing so, try instead using another cable of the same type (ie only genuine or certified).
Also check the charging port on your iPhone and the USB port on your computer for any debris.
