You may need to install firmware for your Samsung Galaxy devices for different reasons. It could be as simple as you trying to update your device to a newer build or Android version. Or it could be that you are looking to fix a soft-bricked device manually as firmware helps a lot when looking for a way to unbrick a device.
Please read in more details below as to how a firmware helps you solve different types of issues. And that includes downgrade too, as also going back to stock
Note The guide for installing a firmware remains the same for all Samsung devices. Yes, all Samsung Galaxy devices. So, whether you own a new or old Samsung Galaxy phone or tablet, feel free to use the guide below.
Installing an official firmware remains an unofficial process and thus you need to be cautious of it. In any case, you only are responsible for your device. We won’t be liable if any damage occurs to your device and/or its components.
Backup, backup, backup!
Make sure you back up important files stored on your device before proceeding with the s below so that in case something goes wrong you’ll have a backup of all your important files. Sometimes, firmware installation may delete everything on your device!
Procedure To Install Stock Firmware On All Samsung Galaxy Devices:
1. Verify that you have downloaded the firmware on your PC. Search our site for it if you don’t have it already.
2. Install Samsung USB driver (method 1 on the linked page) first of all. Double-click the .exe file of drivers to begin the installation. (Not required if you have already done this.)
3. Also, download Odin PC software (latest version).
4. Extract the firmware file using free software like 7-zip. Install 7-zip, then right-click on firmware file and under 7-zip, select ‘Extract here’. You should get files in .tar.md5 format now. (You may a bunch of files, and you will find text like AP, BL, CP or CSC, etc. written at the beginning of those files.) We will be loading this file into Odin, to be installed on the device.
5. Extract the Odin file. You should get the Odin exe file.
6. Disconnect your Galaxy device from PC if it is connected.
7. Boot your device into download mode:
- Power off your device. Wait for 6-7 seconds after the screen goes off.
- Press and hold the following combination of buttons until you see the Warning screen.
- If your device has a Bixby button, then use Volume down + Bixby + Power buttons together (for Note 9 only though, hold Volume down and Bixby, and then connect the USB cable)
- And if your device doesn’t have a home or Bixby button, then use Volume down + Volume up + Power buttons combo.
- If your device has a home button, use Volume down + Home + Power buttons combo.
- Alternate combo: Power + Volume up + Volume down
- Another alternate combo: Press and hold Volume up + Volume down and then insert the USB cable
- Press Volume Up to continue to download mode.
8. Double click on Odin .exe file (from 5) to open the Odin window. Be careful with Odin, and do just as said to prevent problems.
9. Now Connect your device. Odin should recognize your device. It’s a must. When it recognizes, you will see Added!! message appearing in the Log box in the bottom left, and the first box under ID: COM will also show a no. and turn its background blue.
- You cannot proceed until you get the Added!! message, which confirms that Odin has recognized your device.
- If you don’t get Added!! message, you need to install/re-install drivers again and use the original cable that came with the device. Mostly, drivers are the problem (look at 2 above).
- You can try different USB ports on your PC too.
10. Load the firmware files into Odin. Click the AP button on Odin and then select the .tar.md5 file from above. See the screenshot below to find how the Odin window will look like after you have loaded the files.
- Now click on the BL tab, and select the file beginning with BL text.
- Then click on the AP tab, and select the file beginning with AP text.
- Click on the CP tab, and select the file beginning with CP text.
- [Different!] Click on the CSC tab, and select the file beginning with HOME_CSC text. If the HOME_CSC file isn’t available, then select the file beginning with CSC text.
About CSC file: Using the HOME_CSC file won’t reset your device, and data on the phone shouldn’t be deleted. However, when we select a regular CSC file, and it results in CSC on the device being different than that in the CSC file, your phone will be formatted automatically. You can even choose to ignore loading the CSC file, that may do alright too. But if it doesn’t work out, repeat the whole process and select CSC file this time around.
- Info: When you load files, Odin checks the md5 sum of the firmware file, which takes time. So, simply wait until that’s done and the firmware file is loaded. Don’t worry if Odin gets unresponsive for a while, it’s normal. Binary size will also show up in Odin.
One firmware file? If you got only one firmware file after extracting the zip, it’s okay too. It would begin with AP and has to be loaded to the AP tab in Odin. Ignore other tabs in Odin. That’s it.
11. Click on the Options tab, and make sure the Re-partition checkbox is NOT selected. Don’t use the PIT tab, ever.
Go back to the Log tab now, as it will show the progress of the firmware installation when you hit the start button in the next step.
12. Verify that everything is okay. When satisfied, click the Start button on Odin now to start flashing the firmware on your device.
Wait till the installation is finished, after which your device will reboot automatically. You’ll get a PASS message as shown below upon successful installation from Odin.
Some errors you may run into, and with respective solution.
- If Odin gets stuck at setup connection, then you need to do this all again. Disconnect your device, close Odin, boot device into download mode again, open Odin, and then select the file and flash it again as said above.
- If you get FAIL in the top left box, then also you need to flash the file again as stated just above.
