Default [Q] Tricky problem S4

Hey guys,

Iīm running Android 4.4.2 Baseband I9505XXUGNG2 on my Galaxy S4,and after applying a patch via Lucky Patcher (disable signatur verification in package manager) and an automatic reboot,my phone wonīt get into sleep mode.
Also,my mobile doesnīt connect to my WiFi(checking quality of internet connection since reboot)
Even though I had this some time ago,it really sucks to have it now because i hadnīt had this problem when i flashed the newest FW.
The display timeout doesnīt work either.
I hope,anybody of you can help me

EDIT: after waiting for about 20min,my mobile connected with WiFi,displayed me "energy-saving mode activated" and i was able to lock the screen
Edit2: no change after updating to I9505XXUGNG8 and applying those lucky patcher patches... it also seems,that my root access has to "load",because when i open SU,it displays me a message called:there is no SU installed und it also canīt be installed.this is a problem(u donīt say). If you have changed to android 4.3,you have to root your device manually.Please search for the fitting forum.
Edit3: this time it only took about 5min,could live with that period...
Well,so Iīll wait some more minutes till root appears magically...
