Trying to get into safe mode, but blocked by Norton's lock screen

[mifkee]

So far, I've been trying to hold down the power button on the HTC screen, hold the volume down button, and tried holding both buttons at the same time, but I just can't seem to get it into safe mode and uninstall Norton. Am I doing something wrong? I know my volume down button is a little busted and less sensitive, so I'm going to keep trying in the mean time.

[edit] Nevermind, ended up having to clear my storage as a last resort. Also never getting Norton on my phone again. ;-;
