I am trying to remove Lockscreen clock hide but I keep getting an error in red writing. Tried turning phone on and off etc
Ummm what's the error? Can't really help without more info. Post it and we can get a better idea of what's going on. I don't think this will be a major problem. But I've been wrong in the past lol
Try reboot your iPhone. Sometimes i do get that. Just try it again after an hour or so.
Reboot
make sure Cydia is not running in switcher
then run Cydia and uninstall com.hackyouriphone.common
