I have hard reseted this Firefly Mobile in just a couple of minutes. Just watch on my video below. The basic instruction is to press Volume Down and Power Button only. When you see the triangle icon, just press Volume down to go to recovery mode. To select the "wipe data/factory reset" just press and press Volume down until it gets into it. The press Power button to do the process... Watch video below.
This was the status of the unit.
