Me experience says something is wrong with official releases. I managed to boot from Android 5.1.1 and also Longsleep's Linux images (I personally use latest Debian release). In both situations my board boot up in less than a 2 minutes.
I suggest to try Longsleep's images and to burn them with Win32 Image (I think it is also available on his site www.pine64.pro)
For start use higher amps power supply.
And do unpacking of downloaded file (image is usually packed even it says it is img file) to get proper IMG file.
