I have installed the Noki theme and have now got my own wallpaper on there. But for the life of me I can't get rid of the Noki Lockscreen wallpaper. I have SSH'd in with Cyberduck and deleted the png files but still it remains. When I respring the User lockscreen wallpaper I have selected but as soon as Lockinfo loads it goes back to the Noki theme. Some help on removing this would be a great help.
