Samsung Galaxy M33 SM-M336K Firmware (Flash File) Drivers, Tools & Guide
Flashing Samsung firmware with Odin is a process that becomes straightforward once you understand the necessary steps and common pitfalls. This guide collects everything needed for your Samsung Galaxy M33 SM-M336K: the correct firmware file, the appropriate Odin version, and step-by-step instructions that have proven reliable.
Before you begin, make sure to sign out of any Samsung accounts currently active on your device. Skipping this step can lead to Knox triggering a KG lock, which requires additional time and effort to resolve after flashing. Also, official Samsung firmware is always packaged in .tar.md5 format. After you extract the main ZIP file, you should see individual files such as AP_*, BL_*, CP_*, and CSC_* (or HOME_CSC_*). If your extracted files do not match this naming convention, the package you have may not be the correct one for your device.
The Samsung Galaxy M33 SM-M336K firmware package is provided as a compressed ZIP file. You will need to download and then extract this file using a program like WinRAR or 7-Zip. Once extracted, you should find files with names similar to AP_*.tar.md5, BL_*.tar.md5, CP_*.tar.md5, and CSC_*.tar.md5 (or HOME_CSC_*.tar.md5). If these files are not present after extraction, it suggests that you might have downloaded an incorrect firmware package for your specific device model.
Keep in mind that installing stock firmware will erase all data on your device. This is by design, as a clean installation helps resolve various software problems, including Factory Reset Protection (FRP) locks, application conflicts, slow operation, forgotten screen pattern locks, issues where the device is stuck on the logo or does not boot, Wi-Fi and Bluetooth connectivity problems, excessive battery drain, and soft brick situations.
Hard Reset Samsung Galaxy M33 SM-M336K
To perform a factory reset on your Samsung Galaxy M33 SM-M336K without needing a computer, completely power off the device. Then, simultaneously press and hold the Volume Up + Power buttons until the recovery menu appears. If you have an older model with a physical Home button, you would use Volume Up + Home + Power. Once the recovery menu is visible, 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 restores your Samsung Galaxy M33 SM-M336K to its original factory settings. This action is effective for fixing most software-related problems such as slow performance, unexpected app closures, forgotten screen lock passcodes, and issues where the device continuously reboots. If the problem persists even after a factory reset, a complete firmware flash using Odin, as detailed in the subsequent sections, is the next step.
Samsung Galaxy M33 SM-M336K FRP Bypass
The most efficient method to bypass Factory Reset Protection (FRP) on the Samsung Galaxy M33 SM-M336K involves using an Android apps launcher that provides access to device settings during the initial setup wizard. After flashing new firmware or completing a factory reset, you might encounter a Google account lock, also known as FRP. Our free Android apps launcher offers the quickest way to move past this. This is also why I always recommend removing your Google account before flashing your device; it helps you avoid this situation entirely.
Why Do We Need Samsung Galaxy M33 SM-M336K Firmware?

Choosing the Right Firmware Version
Before you start the flashing process, it is important to take a moment and confirm that you have the correct file. Flashing the wrong firmware can create problems that are difficult to fix:
- Identify Your Exact Model Number: Navigate to Settings › About Phone and accurately note your complete model number. For example, your device might be an SM-M336K. The letter suffix is important here; for instance, U/U1 typically indicates a USA variant, W is for Canada, N is for Korea, and B/F usually denotes International or Global versions. Using firmware designed for a different variant can lead to operational problems.
- Match the CSC (Region): The three-letter region code found in the firmware filename needs to correspond with your device’s region. You can find your current CSC by checking Settings › About Phone › Software Information, or by looking at the Service Provider line when your device is in Download Mode. Common codes include XAA (for the US), BTU (for the UK), INS (for India), and SER (for Russia).
- Check the Binary Level: Observe the version string within your device’s current firmware. For example, if you see
XXU9BZDP, the digit after the letters (in this case, ‘9’) represents the binary level. It is crucial to understand that you 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 final four characters of the PDA version provide information about the build date. The first character indicates the year (where A=2024, B=2025, C=2026), and the second character denotes the month (A=January through L=December).
- Verify in Download Mode: Turn off your phone, then hold Volume Down + Power simultaneously to enter Download Mode. This screen will display your exact model number, CSC, and the current firmware version, which you should use to confirm compatibility before proceeding with the flash.

Which Firmware Version Should I Download?
This is a common question, so I have created a simple guide to help you choose. Locate your current situation in the table below to find the recommended file:
| Your Situation | What I Recommend |
|---|---|
| Phone is completely dead or stuck on logo | the latest version, this is the most current Samsung Galaxy M33 SM-M336K firmware available. |
| FRP / Google account lock only | Refer to the FRP bypass guide above; a full firmware flash may not be necessary for this issue. |
| Not sure which region/CSC to download | Check Settings › About Phone › Software Information for your current CSC. Alternatively, enter Download Mode (Volume Down + Power); the CSC will be displayed on the screen. Match this three-letter code (e.g., XAA, BTU, INS) to the firmware filename. |
| Phone slow after a recent OTA update | Consider the next older version. Occasionally, the newest Over-The-Air (OTA) updates introduce unexpected issues, and an earlier build might offer better performance. Always ensure the binary level is the same as or higher than your device’s current binary level. |
| IMEI missing after a previous flash | First, re-flash the latest version, and then proceed with the IMEI repair guide. Do not skip the initial reflash step. |
| the latest version failed with a flash error | Try the next older version instead. Double-check your AP, BL, CP, and CSC file assignments in Odin before concluding that the firmware itself is the issue. |
| Restoring to factory / warranty repair | the latest version is recommended for a clean and fresh start. |
To determine which Samsung firmware is newer, look at the last four characters of the PDA version string (for example, S938BXXU9CZDP). The first character indicates the year (A=2024, B=2025, C=2026), the second represents the month (A=January, B=February… L=December, with Z often signifying a final stable release), and the last two characters denote the revision (ranging from 0-9 then A-Z, where Z is the highest). However, before comparing dates, always verify the binary level; this is the digit just before the date code (for instance, in XXU9CZDP, ‘9’ is the Binary 9). It is not possible to downgrade to a lower binary level. If your device is currently on Binary 9, you should only flash firmware that is Binary 9 or newer. Additionally, ensure the three-letter CSC code in the firmware filename matches your device’s region.
Download Samsung Galaxy M33 SM-M336K Firmware
You can download the official stock firmware for your Samsung Galaxy M33 SM-M336K using the links below. The most current available version is the latest version. After your download is complete, it is important to check that the file size matches what is listed in the table above. A discrepancy in file size often indicates a partial or corrupted download, and flashing a corrupted file can introduce more problems than it solves.
Ensure that you only download firmware that is fully compatible with your exact device model. If you are uncertain, please refer to the firmware selection guide provided above.
- Your model number is a variant of SM-M336K with a different letter suffix. Check About Phone carefully, one letter difference can cause a failed or broken flash.

Prerequisites for Samsung Galaxy M33 SM-M336K Firmware
Review this checklist carefully before you open Odin to flash your Samsung Galaxy M33 SM-M336K. Two common issues I see with Samsung devices are a Samsung account that was not logged out before flashing, which can result in a KG lock, and using a USB cable that only charges the device but fails to maintain a stable data connection during the flash. Always make sure to use a high-quality data-transfer USB cable, not just a charging-only cable.
- Back Up IMEI Numbers: Dial *#06# on your device and record both IMEI numbers now. This information is crucial if you ever need to restore your IMEI after a firmware flash.
- Remove Google Accounts: Sign out of all Google accounts on your phone to prevent Factory Reset Protection (FRP) lock from activating after the flashing process.
- Remove Samsung Accounts: Log out of all Samsung accounts to avoid triggering a KG lock.
- Back Up Your Data: Create a full backup of all your personal data, including photos, contacts, WhatsApp conversations, and any important files. Flashing the firmware will completely wipe your device.
- Charge Your Device: Ensure your device has at least a 50% battery charge. A device that loses power during the flashing process can be very difficult to recover.
- USB Cable & PC: Use a reliable USB data cable, not one designed only for charging, and a Windows computer with available USB ports.
- Install Required Drivers:
- Install the Samsung USB Drivers provided.
How to Install Firmware on Samsung Galaxy M33 SM-M336K
For this process, we will be using Odin. A useful tip: keep both “Auto Reboot” and “F. Reset Time” checked in Odin; these two options together usually lead to the most successful and clean flash. If you are uncertain about which Odin version to use, you can check our Odin versions page, as some older Samsung devices perform better with earlier Odin builds.
- Download and Extract:
- Download the correct firmware package using the links provided earlier in this guide.
- Extract the contents of the ZIP file into a folder with a simple path, avoiding spaces or special characters, as some flash tools may encounter issues with such paths.
- Install the Listed Drivers:
- Confirm that all drivers mentioned above are properly installed on your computer and that your PC has been restarted since their installation. Forgetting to restart is a frequent reason why drivers do not function correctly.
- Load the Firmware File:
- In the Odin program, click on the “BL” button and then select the corresponding BL_*.tar.md5 file. Next, click “AP” and select the AP_*.tar.md5 file. Repeat this process for “CP” and “CSC”. Use the HOME_CSC file if you wish to retain your user data, or choose the regular CSC file for a completely clean flash that wipes all data.
- Connect Your Device:
- Enter Download Mode: First, power off your phone. Then, press and hold Volume Down + Power simultaneously until a warning screen appears. For older models that have a physical Home button, you would also hold the Home button. 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 very important not to disconnect the cable, move the device, or interact with it until the entire process has successfully completed. Interrupting the flash midway is a common cause of devices becoming bricked.
- Wait and Reboot:
- Once the flashing operation has successfully finished, you can safely disconnect your device.
- Power on your device. The first boot after flashing will take longer than usual, sometimes up to 8 minutes, as the system initializes.

What to Expect After Flashing Samsung Galaxy M33 SM-M336K Firmware
Many users contact me believing something went wrong when the outcome was actually normal. Here is a list of common and expected behaviors after a successful Samsung Galaxy M33 SM-M336K firmware flash:
- How to know the flash was successful: Odin will display “PASS.” in green text in the top-left area of its log. Seeing this message confirms that the process completed without issues.
- The first boot will take 3 to 8 minutes, it is important not to force-reboot your device. The operating system is setting itself up from scratch. Interrupting this initial setup is a common cause for devices to enter continuous reboot loops.
- Your phone might feel warm during the first boot, this is a normal occurrence. The warmth will dissipate after a few minutes once the initial application setup is finished.
- All your installed applications will be gone, this is the expected behavior. You will need to reinstall them from the Play Store. If you had an active Google account backup, the setup wizard will typically offer to restore your apps automatically.
- Dial *#06# immediately after setup to verify your IMEI. Do this before you insert a SIM card. If the IMEI shows as “unknown” or “null”, you should follow the IMEI repair guide below before performing any other actions.
- Exercise caution when re-adding your Google account, if you did not remove it before flashing, you might encounter an FRP prompt. Add your account freshly during the initial setup wizard, rather than later through the Settings menu.
- Wi-Fi, Bluetooth, and mobile data should all be functional immediately after setup. If mobile data is not connecting, go to Settings › SIM and Network and manually re-enter your APN details, as flashing can sometimes clear carrier APN configurations.
- Stuck in a bootloop after the first boot? If your device enters a continuous bootloop after its initial startup, go into recovery mode and perform a factory reset from there. Refer to the hard reset guide above. This can happen occasionally and does not necessarily indicate a problem with the firmware; it is usually due to conflicts with residual data from the previous software installation.
- Samsung Smart Switch: After you have finished flashing your Samsung Galaxy M33 SM-M336K firmware, Samsung Smart Switch may prompt you to install additional updates. Allow these updates to complete; doing so ensures your device has the most recent security patches relevant to your region.
Missing IMEI or Corrupt Baseband on Samsung Galaxy M33 SM-M336K After Flashing?
If your Samsung device has a missing IMEI after a firmware flash, it typically indicates a corrupted EFS partition. This partition is responsible for storing your IMEI and other carrier-specific settings. It is important to remember that restoring an IMEI number that does not belong to your device originally is illegal in most countries, so you should only proceed if you are restoring the number your device had before the flash. Specialized tools such as ChimeraTool or BFT can assist with this process. Always verify your local laws before taking any action.

Common Issues When Flashing Samsung Galaxy M33 SM-M336K
- Odin Shows “FAIL” Instead of “PASS”:
- This outcome frequently indicates an incompatibility between the firmware region or model and your device. It is important to confirm your precise model number in Settings › About Phone before selecting the firmware. Even a single letter difference in the model code can lead to problems.
- Samsung Galaxy M33 SM-M336K Not Recognized by Odin:
- Begin by reinstalling the Samsung USB drivers. Make sure your device is properly in Download Mode. If the issue continues, try using a different USB cable, as Odin can sometimes be particular about cable quality.
- KG Lock / Knox Triggered After Flashing:
- This occurs when a Samsung account was still signed in on the device before the flashing process, or if unofficial firmware was used. Always ensure you are logged out of all Samsung accounts before you flash firmware. If KG lock has already been activated, resolving it typically requires a specialized unlocking tool.
- Boot Loop After Flashing:
- If your device enters a continuous boot loop, access recovery mode by holding Volume Up + Power and perform a factory reset from there. This action helps clear any old data from the previous firmware that might be causing conflicts.
