I Cant Shut down iPod Touch 4th Generation

So, I have a friend who has an iPod Touch 4 with 23 million minute lock glitch. Im no expert but I said I would at least attempt to fix it. So first thing was that I had to shut it down, but because the screen was cracked I couldn’t slide the slider to the end, so i searched on the internet. They said hold power and home button at the same time, I tried many times but all that did was restart the iPod Touch. I dont know what to do know. Please Help, Thank You.
