maybe try removing climacon, then reinstalling it?
also have you modified it at all???
my version looks way different than yours!!!
i was using ls climacon... not lsclimacon dark... lemme check again!
what repo did you get it from?
ok i got it from the interwebs, its got a bit more, to get your carrier back you need to remove a folder from the theme...
you can do it using ifile, or ifunbox, or if you donwloaded the theme then sideloaded it you can just delete the them from your device, edit the theme on your computer, then sideload it back on, enable, respring and enjoy...
anyways, for ifile and ifun box navigate on the phones file system to var/stash/themes/ls climacon dark/bundles and then delete the folder title com.apple.ATT_US
if you just do it to the folder on your computer just open up ls climacons dark > library > themes > lsclimacons dark.theme > bundles and delete com.apple.ATT_US.
