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_A520W - AP=AP_A520W - CP=CP_A520W - CSC/CSC_Home=CSC_A520W.
