Rooting how to change CSC without rooting

[Anonymous]

1. First download the firmware.

2. Extract the CSC file from the firmware.

3. Inside the CSC file, there is a lz4 file with the extension.

4. Decompressing will result in an img file with the extension. Unpack the image.

5. Behind the unzipped folder, there is a sec_csc.zip file.

6. Insert sec_csc.zip file into internal memory or Micro SD card.

7. Power off the device and press the volume up + home button + power button simultaneously for 7 seconds.

8. Go to 'Apply update from SD card' and go to sec_csc.zip.

9. When the installation is complete and the device boots, the CSC change is successful.

What application can be used to extract tar.md5 file?

Can I use a csc from another model number i.e from SM-N976Q to SM-N976B?

Can I use odin to flash the CsC file only?
