Samsung Galaxy M31s SM-M317F Firmware (Flash File) Drivers, Tools & Guide
The official Samsung Galaxy M31s SM-M317F firmware package includes everything required to restore your phone using Odin. Flashing a Samsung phone via Odin is a straightforward process when you have the correct files ready. I have organized all the necessary components on this page, including the exact Odin version and step-by-step instructions that actually work.
Before you begin, sign out of any active Samsung accounts on the device. Skipping this step triggers Knox security, leaving you with a KG lock that takes extra time to fix. Samsung packages its firmware in .tar.md5 format. Once you extract the ZIP archive, look for files labeled AP_*, BL_*, CP_*, and CSC_* (or HOME_CSC_*). If these are missing, the package is incorrect.
You will receive the Samsung Galaxy M31s SM-M317F firmware as a compressed ZIP file. Use WinRAR or 7-Zip to extract the contents. Inside, you should find AP_*.tar.md5, BL_*.tar.md5, CP_*.tar.md5, and CSC_*.tar.md5 (or HOME_CSC_*.tar.md5). If these specific files are not visible, you likely downloaded the wrong firmware package for your phone.
Remember that installing stock firmware completely wipes your phone data. This factory reset effect is intentional and clears up various software glitches, including FRP locks, system lag, forgotten pattern locks, devices stuck on the logo, connectivity bugs, battery drain, and soft brick conditions.
Hard Reset Samsung Galaxy M31s SM-M317F
You can factory reset the Samsung Galaxy M31s SM-M317F without a computer by powering it off and holding Volume Up + Power until the recovery menu loads. Navigate using the volume buttons to highlight “Wipe Data/Factory Reset” and press the Power button to confirm your selection.
Performing a hard reset completely wipes your storage and returns the Samsung Galaxy M31s SM-M317F to its factory settings. This resolves standard software hiccups like app crashes, sluggish performance, bootloops, and forgotten screen locks. If the phone still acts up after the reset, proceed to the full Odin firmware flash detailed in the next sections.
Samsung Galaxy M31s SM-M317F FRP Bypass
The most efficient way to bypass FRP on the Samsung Galaxy M31s SM-M317F involves using a free Android apps launcher to access settings during the initial setup. Following a factory reset or a firmware flash, Google Factory Reset Protection (FRP) might lock the phone. You can use our free Android apps launcher to quickly get past this barrier. This is exactly why I always suggest removing your Google account before starting the flash process, it prevents the lock from triggering in the first place.
Why Do We Need Samsung Galaxy M31s SM-M317F Firmware?
Flashing the official Samsung Galaxy M31s SM-M317F firmware is the most reliable way to fix severe software issues, bootloops, and system errors. Samsung phones like the Samsung Galaxy M31s SM-M317F rely on Odin for flashing, no matter which processor they use. If you are experiencing software instability, installing the official stock ROM usually solves it:
- Remove locks if the device is disabled.
- Upgrade to the highest Android version supported by the hardware.
- Eliminate freezing, lagging, and continuous bootloops on your SM-M317F Galaxy M31s.
- Fix battery draining problems and failed OTA updates.
- Return to the original Samsung stock ROM to maintain your warranty status.
- Repair a phone that only boots into the recovery environment.
- Recover from Knox or KG lock issues caused by an interrupted or incorrect flash.
Learn more about stock ROMs and why flashing works.
Choosing the Right Firmware Version
Selecting the correct firmware version is critical before starting the Odin flash process. Taking a few minutes to verify your files prevents difficult recovery situations:
- Identify Your Exact Model Number: Open Settings › About Phone and copy the full model number (e.g. SM-M317F). Suffix letters indicate regions, U/U1 for USA, W for Canada, N for Korea, and B/F for International variants. Flashing a file meant for a different variant causes major errors.
- Match the CSC (Region): The firmware filename contains a 3-letter region code that must match your phone. Check Settings › About Phone › Software Information for your active CSC, or view the Service Provider line in Download Mode. Examples include XAA (US), BTU (UK), INS (India), and SER (Russia).
- Check the Binary Level: Inspect your current firmware version string (e.g.
XXU9BZDP, the digit following the letters represents the binary level). Samsung devices cannot downgrade past their current binary. A phone on Binary 9 requires Binary 9 or higher. - Confirm the Build Date: The final 4 characters of the PDA version reveal the build date. The first character is the year (A=2024, B=2025, C=2026), and the second is the month (A=Jan through L=Dec).
- Verify in Download Mode: Power down the phone, then press Volume Down + Power to access Download Mode. This screen displays your exact model, CSC, and current software version to help you double-check your files.

Which Firmware Version Should I Download?
You should download the firmware version that directly matches your specific issue and current binary level. Readers ask about this constantly, so I created this quick-reference table. Locate your scenario and grab the appropriate file:
| Your Situation | What I Recommend |
|---|---|
| Phone is completely dead or stuck on logo | M317FXXS6DXE6, download this one. It is the latest Samsung Galaxy M31s SM-M317F firmware available. |
| FRP / Google account lock only | See the FRP bypass guide above, you likely do not need the full firmware for this. |
| Not sure which region/CSC to download | Check Settings › About Phone › Software Information for your current CSC, or enter Download Mode (Volume Down + Power), it shows the CSC on screen. Match the 3-letter code (e.g. XAA, BTU, INS) to the firmware filename. |
| Phone slow after a recent OTA update | Try M317FXXS5DXA1, sometimes the latest OTA introduces new bugs and an older build runs better. Make sure the binary level is the same or higher than what your device currently has. |
| IMEI missing after a previous flash | Re-flash M317FXXS6DXE6 first, then follow the IMEI repair guide. Do not skip the reflash. |
| M317FXXS6DXE6 failed with a flash error | Try M317FXXS5DXA1 instead and double-check your AP/BL/CP/CSC file assignments in Odin before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | M317FXXS6DXE6, clean state, fresh start. |
To tell which Samsung firmware is newer, look at the last 4 characters of the PDA version string (e.g. S938BXXU9CZDP). The first character is the year (A=2024, B=2025, C=2026), the second is the month (A=Jan, B=Feb… L=Dec, Z=final stable), and the last two are the revision (0-9 then A-Z, where Z is highest). But before comparing dates, always check the binary level: the digit just before the date code (e.g. XXU9CZDP = Binary 9). You cannot downgrade to a lower binary level. If your device is on Binary 9, only flash Binary 9 or higher. Also make sure the 3-letter CSC code in the firmware matches your device region.

Always ensure the firmware matches your exact device model. Review the firmware selection guide above if you have any doubts.
- Your model number is a variant of SM-M317F with a different letter suffix. Check About Phone carefully, one letter difference can cause a failed or broken flash.
- Your chipset differs from Samsung Exynos 9611. Confirm in recovery mode before proceeding.
- You downloaded the file from a source other than this page.
- The file size differs significantly from the sizes listed in the table above, a size mismatch usually means a partial download, which will fail mid-flash.
Prerequisites for Samsung Galaxy M31s SM-M317F Firmware
Preparing your PC and phone with the correct drivers and a stable USB connection is required before flashing the Samsung Galaxy M31s SM-M317F firmware. Two issues frequently trip people up with Samsung phones: forgetting to sign out of a Samsung account (which triggers KG lock) and using a cheap charging cable that drops the data connection mid-flash. Always grab a high-quality data cable for this process.
- Back Up IMEI Numbers: Dial *#06# and record both IMEI numbers. Keep these safe in case you need to restore your network access later.
- Remove Google Accounts: Sign out of every Google account to prevent FRP lock after the flash.
- Remove Samsung Accounts: Sign out of all Samsung accounts to bypass KG lock.
- Back Up Your Data: Save your photos, contacts, WhatsApp media, and important files. The flash will completely wipe the internal storage.
- Charge Your Device: Ensure the battery is at least 50%. A power loss during a flash is extremely difficult to fix.
- USB Cable & PC: Connect using a proper data USB cable and a Windows computer with functional USB ports.
- Install Required Drivers:
How to Install Firmware on Samsung Galaxy M31s SM-M317F
Installing the Samsung Galaxy M31s SM-M317F firmware requires the Odin flash tool and a Windows PC. We will use Odin for this procedure. A helpful tip: leave “Auto Reboot” and “F. Reset Time” checked in Odin to ensure the cleanest installation. If you need help picking an Odin version, visit our Odin versions page. Certain older Samsung models perform better with specific Odin builds.
- Download and Extract:
- Grab the correct firmware package from the download section.
- Unzip the archive to a simple folder path. Avoid using spaces or special characters in the folder name, as flash tools sometimes fail to read them.
- Install the Listed Drivers:
- Verify that all required drivers are installed and restart your computer. Skipping the restart is a primary reason drivers fail to load.
- Load the Firmware File:
- Inside Odin, click “BL” and choose the BL_*.tar.md5 file. Click “AP” and select the AP_*.tar.md5 file. Do the same for “CP” and “CSC”. Select HOME_CSC to keep your data intact, or CSC for a completely clean wipe.
- Connect Your Device:
- Boot into Download Mode: Turn the phone off, then press Volume Down + Power (add the Home button on older models) until the warning screen appears. Press Volume Up to enter Download Mode.
- Plug the phone into your PC. Odin will display “Added..” in the log box, confirming a successful connection.
- Start Flashing:
- Click the “Start” button to initiate the process.
- Leave the phone completely alone until the process finishes. Unplugging the cable mid-flash will brick the device.
- Wait and Reboot:
- Once Odin shows a successful completion, unplug the phone.
- Turn the device on. The initial boot sequence takes more time than usual, wait up to 8 minutes.

What to Expect After Flashing Samsung Galaxy M31s SM-M317F Firmware
After flashing the Samsung Galaxy M31s SM-M317F firmware, your phone will undergo a lengthy first boot and wipe all previous data. Many people panic during the post-flash phase, but the following behaviors are completely normal:
- How to know the flash was successful: A green “PASS.” message will appear in the top-left corner of the Odin log. Seeing this means the installation worked perfectly.
- First boot takes 3 to 8 minutes: Do not force the phone to restart. The Android system is configuring itself from scratch. Interrupting this stage causes bootloops.
- The phone will feel warm during first boot: This is expected behavior. The device will cool down after the initial setup finishes.
- All your apps are gone: A clean flash removes everything. Download your apps again from the Play Store. If Google Backup was active, the setup wizard will offer to restore your software.
- Dial *#06# immediately after setup: Check your IMEI status before inserting a SIM card. If the screen displays “unknown” or “null”, follow the IMEI repair guide right away.
- Be careful when re-adding your Google account: If you forgot to remove the account earlier, an FRP prompt might appear. Add the account directly through the setup wizard rather than the Settings menu.
- Wi-Fi, Bluetooth, and mobile data: These features should function immediately. If mobile data fails, navigate to Settings › SIM and Network and manually input your APN details, as the flash sometimes clears carrier configurations.
- Stuck in a bootloop after first boot: Access recovery mode and execute a factory reset (see the hard reset guide above). This clears conflicting data from the old system and usually fixes the loop.
- Samsung Smart Switch: Following a fresh Samsung Galaxy M31s SM-M317F firmware installation, Smart Switch might push additional updates. Allow the software to update to guarantee you have the newest regional security patches.
Missing IMEI or Corrupt Baseband on Samsung Galaxy M31s SM-M317F After Flashing?
A missing IMEI or corrupt baseband on the Samsung Galaxy M31s SM-M317F usually indicates a wiped or damaged EFS partition. The EFS partition houses your IMEI and network data. Keep in mind that writing a fake IMEI is illegal in most regions, so only restore the original number that came with the phone. Software like ChimeraTool or BFT can fix this. Verify your local regulations before proceeding.

Common Issues When Flashing Samsung Galaxy M31s SM-M317F
- Odin Shows “FAIL” Instead of “PASS”:
- This typically happens when the firmware region or model does not match the phone. Double-check your exact model number in Settings › About Phone. A single incorrect letter ruins the flash.
- Samsung Galaxy M31s SM-M317F Not Recognized by Odin:
- Reinstall the Samsung USB drivers and confirm the phone is in Download Mode. Swap to a different USB cable, as Odin requires a strong data connection.
- KG Lock / Knox Triggered After Flashing:
- This occurs when a Samsung account remains logged in prior to flashing, or if unofficial software was used. Always sign out of Samsung accounts beforehand. If KG lock is already active, you generally need a specialized unlocking tool.
- Boot Loop After Flashing:
- Boot into recovery mode (Volume Up + Power) and perform a factory reset. This wipes leftover data from the previous operating system that causes the conflict.
Frequently Asked Questions
Q1: Will flashing the Samsung Galaxy M31s SM-M317F firmware erase my data?
A: Yes, installing this firmware via Odin completely resets the device to its factory defaults, including Android 10, upgradable to Android 12, One UI 4.1.
