Default Bootloop trouble HTC One X

Hi all, having some trouble with my HTC One X.
I've had it for about 1.5 years with no problems at all, until tonight.
I was using Snapchat, put the phone down on charger ( was at 5% battery) and then had a nap.
Woke up and found it was boot looping, tried to get into the boot loader but it reboots within seconds of me getting to the boot loader screen and I can't select anything.

Any suggestions?
