This was the appearance of my cellphone after I reset it:
I had installed KISS, and also I had deleted the Linage OS launcher (Trebuchet) , finally I made KISS a system app, thus, it became part of my custom ROM and persisted the reset.
Note: First install KISS because deleting Trebuchet is very likely to ruin your system
I did all that using Link2SD, I uninstalled that app after using it because it have ruined my system 3 times (because I love to uninstall everything I don't like)
And I recommend you a lot the KISS launcher; I'm feed up with widgets and screens, I just keep my cellphone simple, this launcher is really slim and fast. And it will help you to get the things done. That's all.
