Okay I just got home and realised the phone was hot from turning itself on and off. I managed to turn it off and QHSUSB_DLOAD it again before I left so I fixed it and went on my jolly way.
Just got back tried to turn it off again as I have to go out soon again and wouldn't have time for the method you just gave me, but this time it just rebooted straight into Android... I must say I'm extremely confused yet happy.
The phone isn't rooted however and I'll have to retry tomorrow morning.
Thanks for your help, if you have any tips so that this doesn't happy again, I'm more than happy to hear them haha.
