If you own a Samsung Galaxy device and you do different experiments or enrol your devices into beta firmware. Then you might have found yourself in need of firmware files for your Samsung Galaxy device. Well, there are a lot of different websites and tools that provide firmware files for Samsung devices. In fact tools like Frija and SamFirm also gives the ability to download the BL, AP, CP, CSC and HOME CSC files from the firmware of the device. Usually, for any Samsung Galaxy device running One UI, you need Odin on a PC to install the firmware. Be it updating a firmware downgrading or re-flashing a firmware all of this can be done with the help of Odin. The basic method of flashing firmware on a Samsung device is pretty different from any other device like Xiaomi, or OnePlus.
For Samsung you need to flash 4 different binary files using Odin, then only you will be able to complete the process of installing firmware. For most of the OEMs, it is just one zip file that can be sideloaded using ADB. But for Samsung, there are 5 different files out of which 4 needs to be flashed and they are written below.
- CSC or Home CSC
The only way to download the above-mentioned binaries for your device is to download the whole firmware, there is no other way through which you can individually download the files. So, to get these files you need to download the whole firmware zip file and then to obtain the BL, AP, CP and CSC or Home CSC files you need to extract the zip file. Once you get all of the files, you are ready to flash them using Odin.
What are BL, AP, CP, CSC and Home CSC?
If you have been using Android devices for long enough then you might know that the core of the Android devices depends on recovery, fastboot, bootloader, vendor, EFS, modern and kernel. All of the mentioned files are stored inside the zip of the firmware files or it is stored as a .img file. However, when it comes to Samsung devices, they go through a different approach, since Samsung pack each of these files inside a different file which is individually encrypted and to decrypt them you need the official flashing tool, Odin. Detailed information about the files BL, AP, CP, CSC and Home CSC is right below.
- BL- BL stands for Bootloader. The BL binary with extension as .tar.md5 is flashed to install the bootloader on your Samsung Galaxy device.
- AP- AP is the abbreviated form of Android Processor. It is the largest file out of the lot. Ap is responsible for flashing the system partition of your Samsung Galaxy device.
- CP- CP stands for Core Processor. The Core Processor file handles the modem of the device, so when we flash the CP file using Odin it installs the system modem on your Galaxy device.
- CSC- CSC stands for Country Specific Code or Consumer Software Customization. It plays a very important role in flashing the firmware on a Samsung device. As Samsung’s firmware is very much specific to countries and regions. This is mainly because Samsung uses different chips in different regions and there are certain features that vary from region to region like carrier branding, APN settings and more. So if you are flashing firmware and wants to clean flash it then you should use the CSC file. Only one of the files is needed to flash either Home CSC or CSC. So if you flash the CSC file it will wipe all the apps data, settings and files of your device and your device will reset to the factory status. You can also use a different region’s CSC if you want to change the region of the firmware you are using.
- Home CSC– Home CSC is more or less the same thing as CSC except it doesn’t wipe the data and doesn’t change the region of the firmware or anything, use this if you don’t want to lose or wipe apps and app data of your device.
Need of Downloading the Samsung Firmware?
There could be several different use case scenarios of downloading firmware for your Samsung device. For instance, if you want to change the region of the firmware you are using or if you want to clean flash the firmware on your device as you might be facing some issues. or if the software update isn’t coming on your device, but the rest of the people have already got the update, then surely you can download and flash the latest firmware on your device. Mostly, people don’t feel the need of downloading firmware on a Samsung device, but Samsung gives an option to flash firmware then you can surely install it if you feel the need of doing it.
A few of the situations where we feel the need of downloading firmware with the files like BL, CP, AP and CSC binaries are necessary to have mentioned below.
- Downgrading the System Firmware- Sometimes OEMs push the latest version of Android in a hurry which carry some unfixed bugs and can cause performance issues. So if you have by chance updated to the latest firmware and wants to downgrade to the previous version of the OS, then you need to download the firmware.
- Going From Beta Build to Stable– Samsung also launches a Beta channel for a few of their Samsung devices, and if you enrol into that then your phone will have beta firmware of the latest Android version, however, to go back to the stable version in between then you might need to download and flash the firmware manually.
- Stuck in boot loop– If your Samsung device is stuck in the boot loop which means you are unable to turn on your device at all to fix any issues or do anything. In such a case, you need to do a clean of the flash firmware as you cannot perform a factory reset or anything since the phone isn’t turning on.
- Change CSC– If you have your Samsung device imported from some other region or country or if you are using the phone in a different country from where you have purchased then you might need to flash the firmware while changing the CSC. You can also change the CSC if you feel the same phone is getting software updates faster in a different region than yours, just make sure the model number of the device is matching with the model number of the firmware you have downloaded.
- Manual Software Update- So, if you are using your Samsung Galaxy device in a different region from where it was purchased, chances are you might not receive OTA updates or you might get delayed updates, in such case you can always manually flash the latest firmware manually and update your device with the help of Odin flash tool.
