→ This page is for regular Galaxy S10, while for the bigger variant, the S10+, check out our Galaxy S10+ firmware page.
Samsung new flagship for the year 2019, the Galaxy S10, is a powerful device that comes with Exynos 9820/Snapdragon 855 chipset. Not only that, the software on the Galaxy S10 is quite good, Samsung’s best yet in One UI skin that runs Android 9 Pie at the base.
Despite that, though, you may run into software issues on your Galaxy S10. Whether that be because of a bad app, or any customization you may have tried, you can fix the software issues yourself by simply installing a firmware file.
That is why you must keep a firmware file of your device — for the exact variant — handy, saved on your PC, to go back to stock effortlessly, all by yourself. A firmware file also comes handy when you want to update your phone to latest software update available — particularly helpful if you are not getting OTA updates from the OEM.
On this page, you will find firmware file for various Galaxy S10 variants. You can easily install a firmware file using unofficial Samsung PC software called Odin, as provided in the guide below.
The Galaxy S10 firmware files given here are 100% free to download and doesn’t require any subscription.
If you are in the U.S., you will be glad to know that firmware files are being made available for the T-Mobile, Sprint, Verizon Wireless, AT&T, US Cellular, unlocked variant, and more carriers
How to download the correct firmware file
This is an important part!
Be sure to check and find the correct model no. of your Galaxy S10. Then, based on your device’s model no., look for the appropriate firmware build from above.
You can identify the model no. using an app called Droid Info, or simply check it on its packaging box, or under Settings > About. Another solid trick would be to look at the packaging box of your device (in case you can’t power on the device because it is bricked).
Now that you know the model no., download the latest firmware from above for that model no. exactly.
Next, install the firmware on your Galaxy S10 by following the guide linked right below.
Firmware cross-compatibility
You can install any firmware for the model no. SM-G970U on your device as it doesn’t matter as long as the model no. remains the same.
Yes, this means that you can install a firmware file originally meant for T-Mobile or Verizon variant on your AT&T S10, and vice versa. The only difference will be the extra apps (read: bloatware) that each carrier may out in or not put in, in which case, you are always better off AT&T firmware.
The other firmware files are as per your device’s model no., as usual, so just find your model no. on the box first, and then download the firmware given for that model no. in the table right below.
Note: You can install SM-G970U1 firmware on an SM-G970U device, but not vice-versa. Also, Canadian Galaxy S10+ comes with model no. SM-G970W, not U.

How to install a firmware
First, read our disclaimer, then take backup and then follow the guide below to install the firmware.
Disclaimer: Installing an official firmware through Odin doesn’t void your device’s warranty, but it 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! Create an appropriate backup of contacts, pictures, videos, songs and other important files stored on your device before proceeding with the steps 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! Like, when you change the CSC of your device, knowingly or not.
Step-by-step Firmware Installation Guide
Let’s see how to install the firmware on your Galaxy S10. Make sure you have more than 30% battery on your device.
Step 1. Make sure you have downloaded the firmware on your PC. Search our site for it if you don’t have it already.
Step 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.)
Step 3. Also, download Odin PC software (latest version or patched version of 3.13).
Step 4. Extract the firmware file now. You can use free software like 7-zip for this. 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.
Step 5. Extract the Odin file. You should get the Odin exe file (other files could be hidden, hence not visible).
Step 6. Disconnect your Galaxy device from PC if it is connected.
Step 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 three buttons Volume down + Bixby + Power together until you see the Warning screen.
- If your device has a home button, use Volume down + Home + Power buttons combo.
- If your device doesn’t have a home or Bixby button, then use Volume down + Volume up + Power buttons combo.
- Press Volume Up to continue to download mode.
Step 8. Double click on Odin .exe file (from step 5) to open the Odin window as shown below. Be careful with Odin, and do just as said to prevent problems.
Step 9. Connect your device now using the USB cable. 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. Look at the pic below.
- 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 step 2 above).
- You can try different USB ports on your PC too.
Step 10. Load the firmware files into Odin. Click the AP button on Odin and the 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.
- Click on BL tab, and select the file beginning with BL text.
- Click on AP tab, and select the file beginning with AP text.
- Click on CP tab, and select the file beginning with CP text.
- [Different!] Click on CSC tab, and select the file beginning with HOME_CSC text. If 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 regular 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 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.
Step 11. Click on Options tab, and make sure 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.
Step 12. Verify that everything is okay as mentioned above. When satisfied, click the Start button on Odin now to start flashing the firmware on your device.
Wait till installation is finished, after which your device will reboot automatically. You’ll get 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.
Done!
