Default TouchWiz crashed after modding SecSettings

I modded the stock SecSettings to add a logo in the About Device section, and recompiled the APK without any errors. Added the modified SecSettings into my ROM and flashed the phone. But when I open Settings, TouchWiz crashes.

Could someone please help me with this? Thank you.
