Download your tar file for stock rom from sammobile.com Download Odin.
Unzip the zip file to get tar. Go to download mode in phone and connect to PC. Open Odin and put the tar file in PDA. Check only autoreboot and f time reset. Leave others unticked.
Press start and wait for ROM to be flashed. It will take some time( unplug only after it says pass with green light).. After stock ROM is flashed, factory reset again. Then flash your custom recovery and your desired ROM. Remember , while flashing custom ROM, follow the instructions given in the respective thread.
This will be a clean install and the errors will go away, at the cost of your internal data being wiped.

You probably changed something you shouldn't have. Wiping data/cache can only remove the apps you used to alter things, but it won't touch the system files or kernel files you have already altered. You need flash the ROM or firmware that you are using again to get your files back to normal. Make sure you backup your data first.
