My whole life I have no idea to GET THIS ROM WORKING PROPERLY!!

((
I have just installed the newest update of this firmware >lineage-16.0-20201126-nightly-kccat6-signed< (link: on post). It is installed successfully and worked smoothly AT THE FIRST TIME AS IF A DREAM

).
But ... when I tried to remove some apps that no use such as "Email", "Browser", "Keybard" (I use Laban Key cus I'm Vietnamese), and "Calculator" (I use CalcES for better studying); and recheck some important settings such as Development, disable SELinux (no idea who set SELinux for this ROM as Enabled, really want it to be Disabled or Enforce/ Permissive instead

), or disable auto-update for this android (cus I rooted the device with Magisk (newest version I pretty sure): after a while it get bootloop

(?? I means: the f**k??? It also get bootloop the first time I checked patched to Android with Lucky Patcher

(??? Thats why I have no idea what did the crash (or bug): Lucky Patcher or the System??
On the otherhand, Camera is good
... But my device got a restart (no bootloop) when I trying to use QR code scanning - mode or View photos (no idea either)
Please help me guys, I'm pretty sure my device is Samsung Galaxy S5+ (kccat6xx) (but in CPU-Z it named Samsung Galaxy S5 LTE-A(lentislte)) (there just one thing I can sure: my device's model is <SM-G901F>

).
