"error access denied" means you need to switch ports or select New Security.

If you select New Security and it checks for the superuser and finds false, go download towelroot and root your device first. Then try again.

Also, if towelroot does not root, you may need to downgrade your baseband first, then root, then unlock, then reflash original baseband (that only applies if you have 4.4.4 Android).
