Before you start following the instructions, there are a couple of things you should do first. The instructions below will take you through the complete process in a step-by-step and comprehensive manner. The easiest solution here would be simply skipping the CSC files as it is not required unless you are changing your CSC value of the Samsung device. If you get FAIL in the top left box, then also you need to flash the firmware again as stated just above.

Another option is to check the original packaging that your TV came in. The model number is usually printed on the box or on a label affixed to the box. If you don’t have the model number, you can use the “Auto-detection” feature.

Stock ROMs code is developed and maintained by the company manufacturers. Click the “CSC” button and select the firmware file for the country or region of your device. Click the “CP” button and select the firmware file for phone. In Odin interface, Click the “BL” button and select the firmware file for bootloader. This option appeared in Odin’s version 1.3 and what it does is erase the contents of the phone’s /efs folder, so you must never mark. The EFS folder contains important data such as your smartphone’s IMEI, Sales Code or Product Code, among others, and are essential for normal operation of the terminal.

Hence, download and install the correct version of the Odin tool for your device. There are some combination files for some specific devices, these are modified ROMs that help you bypass the Google lock. They are not available for all models specially for latest flagship models such as Galaxy S22, S21, Note20 and any latest Samsung models running Android 11 and above.


Now, you need to add the firmware binaries to the Odin flash tool. Click on the BL button, navigate to the folder where you extracted the firmware files with .tar.md5 extension, and add the binary that starts with ‘BL_’ in its name. This box is the one you will use to place the file containing the new official stock firmware, ROM or recovery we have previously downloaded can be updated through odin. The file usually is a .md5 or .tar file containing the complete picture of the ROM or recovery. Once the firmware has downloaded, verify that all the information presented on your screen is about your device. Choose the “start option and put your device in download mode by following the simple on-screen instructions.

You can change auto-update options by changing your settings within the Product account information. In very limited cases, updates may still be automatically applied, regardless of the auto-update setting. For example, we may provide an automatic update that fixes a security breach or vulnerability to your network. These data files do not update your firmware but consist of Software files that are cached on your Product and override older files.

Where to download stock firmware

We purchased a device already that was advertised with Tizen to test with. However, it does not update beyond version 1106. If your TV continues to turn on in the middle of the night for an extended time for others, you may have a defective TV.
