If your SM-S936W Galaxy S25+ is having software problems, installing the official Samsung Galaxy S25+ SM-S936W firmware can often get it back on track. This article provides all the files and guidance you need, covering hard resets, FRP bypass steps, flash files, IMEI repair tools, drivers, and the exact flashing procedure.
Device: Samsung Galaxy S25+ SM-S936W | Chipset: Qualcomm Snapdragon 8 Elite (SM8750-AB) | Flash Tool: Odin
Android: Android 15, One UI 8 | File Type: .tar.md5 / ZIP (Contains AP, BL, CP, CSC files for Odin)
⚠ Warning: Flashing erases all data. Back up first.
Samsung Galaxy S25+ SM-S936W Firmware (Flash File) Drivers, Tools & Guide
Installing Samsung firmware using Odin is straightforward once you understand the necessary steps and preparations. I have gathered all the information you need on this page: the correct Samsung Galaxy S25+ SM-S936W firmware file, the right Odin version, and a reliable flashing guide.
Before you begin, make sure to sign out of any Samsung account on your device. Skipping this step can trigger Knox (KG lock), which adds extra complications after flashing. Also, remember that official Samsung firmware files come in a compressed .tar.md5 format. After you extract the main ZIP file, you should see individual files like AP_*, BL_*, CP_*, and CSC_* (or HOME_CSC_*). If your extracted files do not match this pattern, you might have an incorrect package.
Your Samsung Galaxy S25+ SM-S936W firmware arrives as a compressed ZIP file. You will need to download and extract it using a program like WinRAR or 7-Zip. After extraction, you should find files such as 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, the firmware package you have might not be the correct one for your device.
Keep in mind that flashing stock firmware will erase all data on your device. This is often the intended outcome, as it helps to resolve various software issues including FRP lock, application problems, slow performance, forgotten pattern locks, a device stuck on the logo, Wi-Fi and Bluetooth connectivity issues, excessive battery drain, and soft brick situations.
Hard Reset Samsung Galaxy S25+ SM-S936W
To factory reset your Samsung Galaxy S25+ SM-S936W without a computer, ensure the device is fully powered off, then press and hold the Volume Up + Power buttons simultaneously until the recovery menu appears. For older models that still have a Home button, you would use Volume Up + Home + Power. Once in the menu, navigate to “Wipe Data/Factory Reset” using the volume keys and confirm your selection with the Power button.
Performing a hard reset clears all user data and returns the Samsung Galaxy S25+ SM-S936W to its original factory settings. This action can resolve a majority of software issues such as slow operation, app crashes, forgotten screen locks, and repeated boot cycles. If the problem continues after a factory reset, you will want to consider a full firmware flash using Odin, which is covered in the sections that follow.
Samsung Galaxy S25+ SM-S936W FRP Bypass
The quickest way to bypass FRP on a Samsung Galaxy S25+ SM-S936W is to use a specific Android apps launcher that allows access to device settings during the initial setup process. After flashing or a factory reset, you might encounter a Google account lock, also known as FRP. Our free Android apps launcher provides the fastest method to get past this lock. This is also why I always suggest removing your Google account before you flash, as it helps you avoid this problem completely.
Why Do We Need Samsung Galaxy S25+ SM-S936W Firmware?
Official firmware is necessary for Samsung devices like the Samsung Galaxy S25+ SM-S936W because it allows for device flashing using Odin, regardless of the internal chipset. Whether you are dealing with startup issues or other software glitches, flashing the proper firmware can provide a solution:
- You can unlock your device if it has become locked or disabled.
- It enables updating to the most recent Android version supported by your phone.
- It helps fix recurring startup loops, lagging performance, and freezing on your SM-S936W Galaxy S25+.
- You can resolve problems with OTA update failures and issues with battery draining too quickly.
- It lets you restore the original Samsung stock ROM to maintain your warranty validity.
- You can recover your device when it only boots into recovery mode.

You can learn more about stock ROMs and why flashing can fix problems.
Choosing the Right Firmware Version
Before you start the flashing process, it is important to take a moment and confirm that you have selected the correct firmware file. Flashing an incompatible firmware can lead to issues that are difficult to resolve:
- Identify Your Exact Model Number: Navigate to Settings › About Phone and carefully write down your full model number (for example, SM-S936W). The letter suffix is very important, U/U1 typically means USA, W is for Canada, N is for Korea, and B/F is often for International or Global variants. Flashing firmware intended for a different variant can cause serious problems.
- Match the CSC (Region): The three-letter region code found in the firmware filename needs to match your device’s original region. You can find your current CSC in Settings › About Phone › Software Information, or by looking at the Service Provider line when in Download Mode. Common codes include XAA (US), BTU (UK), INS (India), and SER (Russia).
- Check the Binary Level: Observe the version string of your device’s current firmware (for example,
XXU9BZDP, the number directly after the letters indicates the binary level). You absolutely cannot downgrade to a lower binary level. If your device is currently on Binary 9, you should only flash firmware that is Binary 9 or higher. - Confirm the Build Date: The last four characters of the PDA version string provide details about the build date. The first character represents the year (A for 2024, B for 2025, C for 2026), and the second character indicates the month (A for January through L for December).
- Verify in Download Mode: Turn off your device, then press and hold Volume Down + Power to enter Download Mode. This screen will clearly display your precise model number, CSC, and the current firmware version installed. Use this information to double-check everything before you proceed with flashing.

Which Firmware Version Should I Download?
Many people ask about choosing the right firmware, so I have created a straightforward guide below. Just find the description that matches your current situation in the table and it will point you to the correct file:
| Your Situation | What I Recommend |
|---|---|
| Phone is completely dead or stuck on logo | S936WVLS8BZBB, this is the most current Samsung Galaxy S25+ SM-S936W firmware available. Start with this one. |
| Only experiencing FRP / Google account lock | Please refer to the FRP bypass guide mentioned above. You likely do not need to flash the entire firmware just for this. |
| Unsure which region/CSC to download | Check your current CSC by going to Settings › About Phone › Software Information, or by entering Download Mode (hold Volume Down + Power). The CSC is shown on the screen. Match the three-letter code (e.g., XAA, BTU, INS) with the firmware filename. |
| Phone performance is slow after a recent OTA update | Consider trying the next older version of the firmware. Sometimes the most recent OTA can introduce new bugs, and an earlier build might run more smoothly. Just make sure the binary level is equal to or higher than what is currently on your device. |
| IMEI is missing after a previous flash | First, re-flash S936WVLS8BZBB, and then follow the IMEI repair guide. It is important not to skip the re-flash step. |
| S936WVLS8BZBB failed with a flash error | Try the next older version instead. Also, double-check your AP/BL/CP/CSC file assignments in Odin before assuming the firmware itself is the issue. |
| Restoring to factory settings / preparing for warranty repair | S936WVLS8BZBB, this will provide a clean, fresh start for your device. |
To determine which Samsung firmware is newer, look at the last four characters of the PDA version string (for example, S938BXXU9CZDP). The first character denotes the year (A for 2024, B for 2025, C for 2026), the second represents the month (A for January, B for February… L for December, with Z typically indicating a final stable build). The final two characters are the revision (ranging from 0-9 then A-Z, where Z signifies the highest revision). However, before comparing dates, always check the binary level, which is the digit found just before the date code (e.g., XXU9CZDP indicates Binary 9). You absolutely cannot downgrade to a lower binary level. Therefore, if your device is running on Binary 9, you must only flash firmware that is Binary 9 or a higher version. Make sure the three-letter CSC code in the firmware also matches your device’s region.

Prerequisites for Samsung Galaxy S25+ SM-S936W Firmware
Before you open Odin to flash your Samsung Galaxy S25+ SM-S936W, go through this checklist. Two common issues I have seen with Samsung devices are not signing out of a Samsung account before flashing, which can activate KG lock, and using a USB cable that only charges instead of providing a stable data connection during the flash. Always use a proper data cable.
- Back Up IMEI Numbers: Dial *#06# and record both of your IMEI numbers now. You will need these if you ever have to restore your IMEI after the flashing process.
- Remove Google Accounts: Sign out of all Google accounts on your device to prevent an FRP lock from activating after the flash.
- Remove Samsung Accounts: Sign out of any Samsung accounts to avoid triggering a KG lock.
- Back Up Your Data: Back up everything that is important to you, photos, contacts, WhatsApp chats, and any other critical files. Flashing will completely erase your device.
- Charge Your Device: Ensure your device has at least a 50% battery charge. A device that loses power during a flash can be very difficult to recover.
- USB Cable & PC: Use a proper data-enabled USB cable, not just a charging cable. You will also need a Windows computer with available USB ports.
- Install Required Drivers:
- Make sure the Samsung USB Drivers are installed on your computer.
How to Install Firmware on Samsung Galaxy S25+ SM-S936W
For this process, we will be using Odin. A helpful tip I can offer: keep both “Auto Reboot” and “F. Reset Time” checked within Odin. These two options together usually give you the cleanest and most successful flash result. If you are unsure which Odin version to use, you can check our Odin versions page, as some older Samsung devices might work better with earlier Odin builds.
- Download and Extract:
- Download the correct firmware package from the links provided above.
- Extract the contents of the ZIP file to a simple folder path on your computer. Try to avoid paths that contain spaces or special characters, as some flash tools may have difficulty with them.
- Install the Listed Drivers:
- Confirm that all drivers mentioned earlier are properly installed and that your PC has been restarted since their installation. Forgetting to restart is a common reason why drivers sometimes do not function correctly.
- Load the Firmware File:
- In the Odin program, click the “BL” button and then select the
BL_*.tar.md5file. Next, click “AP” and choose theAP_*.tar.md5file. Repeat this process for “CP” and “CSC.” Use theHOME_CSCfile if you wish to retain your user data, or the regularCSCfile for a complete clean flash.
- In the Odin program, click the “BL” button and then select the
- Connect Your Device:
- Enter Download Mode on your phone: Turn off the device completely, then press and hold the Volume Down + Power buttons simultaneously (if your model is older and has a Home button, add that to the combination) until you see the warning screen. Press Volume Up to confirm and proceed into Download Mode.
- Connect your phone to your PC using a USB cable. Odin should display “Added..” in its log area, indicating that your device has been successfully detected.
- Start Flashing:
- Click the “Start” button in Odin to begin the flashing process.
- It is crucial not to disconnect the phone, move the USB cable, or touch the device until the entire process is finished. Disconnecting during a flash is how devices can become bricked.
- Wait and Reboot:
- Once the flashing completes successfully, you may disconnect the device from your computer.
- Power on your phone. The first boot cycle will take longer than usual, please allow it up to eight minutes to complete.

What to Expect After Flashing Samsung Galaxy S25+ SM-S936W Firmware
I often hear from people who are concerned that something went wrong after a flash, when in fact, everything is completely normal. Here is what you should expect after a successful Samsung Galaxy S25+ SM-S936W firmware flash:
- How to know the flash was successful: Odin will display “PASS.” in green text in the upper-left corner of its log window. If you see this, the process completed without issues.
- The first boot takes 3 to 8 minutes, it is important not to force-reboot the device during this time. The operating system is configuring itself from scratch. Interrupting this phase can cause your device to enter a bootloop.
- The phone will feel warm during the first boot, this is a normal occurrence. The temperature will stabilize after a few minutes once the initial application setup is complete.
- All your applications are removed, this is an expected outcome. You will need to reinstall them from the Play Store. If you had a Google account backup active before the flash, the setup wizard will offer to automatically restore your applications.
- Dial *#06# immediately after setup to verify your IMEI. Do this before inserting a SIM card. If the IMEI appears as “unknown” or “null,” you should follow the IMEI repair guide below before proceeding with anything else.
- Be careful when re-adding your Google account, if you did not remove it before flashing, you might see an FRP prompt. Add it as a fresh account during the initial setup wizard, rather than later through the Settings menu.
- Wi-Fi, Bluetooth, and mobile data should all function correctly immediately after setup. If mobile data is not connecting, go to Settings › SIM and Network and manually re-enter your APN settings; sometimes a flash can clear carrier-specific APN configurations.
- Stuck in a bootloop after the initial boot? Enter recovery mode and perform a factory reset from there. Refer to the hard reset guide above. This can happen occasionally and does not mean the firmware is incorrect; it is usually a conflict with residual data from the previous installation.
- Samsung Smart Switch: After you have flashed your Samsung Galaxy S25+ SM-S936W firmware, Samsung Smart Switch might prompt you to install additional updates. Allow these updates to complete; this helps ensure your device has the latest security patches specific to your region.
Missing IMEI or Corrupt Baseband on Samsung Galaxy S25+ SM-S936W After Flashing?
A missing IMEI on a Samsung device following a firmware flash typically indicates a corrupted EFS partition. This partition is where your IMEI and carrier settings are stored. Please be aware that restoring an IMEI that is not your device’s original number is illegal in most countries, so you should only proceed if you are restoring the exact number your device had before you flashed. Tools such as ChimeraTool or BFT can assist with this process. Always check your local laws before proceeding.

Common Issues When Flashing Samsung Galaxy S25+ SM-S936W
- Odin Shows “FAIL” Instead of “PASS”:
- This usually suggests an incompatibility between the firmware’s region or model and your actual device. It is important to confirm your precise model number in Settings › About Phone before you choose the firmware. Even a single letter difference in the model code can lead to problems.
- Samsung Galaxy S25+ SM-S936W Not Recognized by Odin:
- Start by reinstalling the Samsung USB drivers. Ensure your device is properly in Download Mode. If it still does not connect, try using a different USB cable, as Odin can sometimes be sensitive to cable quality.
- KG Lock / Knox Triggered After Flashing:
- This occurs when a Samsung account remained signed in on the device before flashing, or if unofficial firmware was used. Always make sure to sign out of all Samsung accounts before you flash. If KG lock is already active, you will generally need a specialized unlocking tool.
- Boot Loop After Flashing:
- Enter recovery mode (hold Volume Up + Power) and then perform a factory reset from that menu. This action clears any old data from the previous firmware that might be causing a conflict with the new installation.
