Problem: Phone battery ran out. Popped spare battery in and the boot loop began. Can only go so far where the screen says "Samsung Galaxy S3 i9300" and nothing further.
Tried with no success:
- Flicking power button several times
- Vol Up + Home + Power = loop persists
- Vol Down + Home + Power, then Vol Up to select Continue and screen is just stuck in "Downloading.. Do not turn off target"
Please help :(
