How to check and change CSC files on your Samsung smartphones and Tablets

On older Samsung Galaxy handsets released before 2016, the firmware had just one file having .tar.md5 extension. Although Odin3 v3.07 and lower versions had PDA, Bootloader, Phone, and CSC fields. You had to flash single-file firmware by adding it to the PDA sections. Later, Samsung decided to split the firmware files into four binaries and from Odin v3.09 and newer variants, AP, BL, CP, and CSC got introduced. There are two types of CSC files in your Samsung device’s firmware folder – CSC and Home CSC.

The difference between CSC and Home CSC

When you extract the Samsung firmware zip file, you will come across 5 binaries inside it. You’ll be able to use the Frija Samsung firmware download tool or other resources for downloading Home CSC, CSC, AP, BL, and CP files for Odin. It can be easy to add the corresponding firmware binaries to different fields in Odin. You might even get confused about whether you’re flashing CSC or Home CSC in Odin. Here is how the two of them are different from each other. Once you understand their respective purposes, you do not have any confusion.

CSC

If you want Odin to wipe off all third-party apps, data, and settings to perform a factory reset while installing the firmware, you need to add the CSC binary to Odin. When your Samsung smartphone or Galaxy Tab boots up, it’ll will end up in the same state as it was upon purchase. You’ll need to set up your device and then log into your Google and Samsung accounts again. The images, videos, audios, and other files present in the internal storage will get deleted. Flashing the CSC binary results in a clean installation. If you feel that your Samsung device is slow and experiencing lag or misbehavior, wiping off the device will help fix these issues.

Home CSC

If your main purpose is to re-install the firmware or update your device’s software without wiping your apps, settings, and user data, you need to go with the Home CSC binary. Choosing these files will only affect the software version of your device while keeping everything else intact.
