S21 5G SM-G991U1

What is the difference between 1 file firmware and 5 files:
It is known that when you download any firmware for your Galaxy device from sites known to download the firmware such as Sammobile, the firmware contains one file where it updates the Android operating system without deleting anything and the file is used by the Odin Tool in box AP.
But there are firmware of another type are characterized by being more comprehensive and larger containing four files and they are BL-AP-CP-CSC-CSC HOME, They are called several labels: Repair Firmware-Full Firmware-Factory Firmware-Factory Roms,These files are flashed by the Odin tool in the following order BL=BL_G991U1 - AP=AP_G991U1 - CP=CP_G991U1 - CSC/CSC_Home=CSC_G991U1.

What is the difference between CSC or CSC HOME:

CSC: It is the file responsible for the languages ​​of the device but when used it will delete all files on the device (lost data).
CSC HOME: It is the file responsible for the languages ​​of the device, but when used will not delete anything from the device (unformat).
