Custom SlantedLock Wallpaper
currently the default option for SlantedLock is not working properly. here is what i did as a workaround via SSH
if you're a windows user i prefer this method:
iPhone Folders
go into your themes and find
var>stash>themes>SlantedLock.theme>Private>images>slbkg24hr
now, you're going to have to add 24 images (custom wallpaper) of the same into this folder and then rename to what the existing files are named
for example:
0.jpg
1.jpg
2.jpg
etc...
make sure to backup, delete .. or whatever you would like to do with the originals (personally i did not like them so i got rid of them)
in your
slanted lock configurations under the
wallpaper set: select
24 hr
respring. done
