I have the banner reading "Not Enough Storage" and the screen is locked plus I can't reset it because my home button is broken. What can I do?

Please help! My ipod is displaying the "Not Enough Storage" banner but it won't let me close out of it or go to settings- it's locked. On top of that I can't reset due to the fact that my home button is broken. I have the accessability thingy but pressing home on that and the power button at the same time doesn't reset it. Anyone know how to fix this? Please and thank you!!
