You can repair your SM-M015F Galaxy M01 using the official Samsung Galaxy M01 SM-M015F firmware. This page provides the exact files and instructions required for a hard reset, FRP bypass, IMEI repair, or general software fix.
Device: Samsung Galaxy M01 SM-M015F | Chipset: Qualcomm Snapdragon 439 (SDM439) | Flash Tool: Odin
Android: Android 10 (One UI Core 2.0), upgradable to Android 11 (One UI 3.1) and Android 12 | File Type: .tar.md5 / ZIP (Contains AP, BL, CP, CSC files for Odin)
⚠ Warning: Flashing erases all data. Back up first.
Samsung Galaxy M01 SM-M015F Firmware (Flash File) Drivers, Tools & Guide
Flashing Samsung firmware with Odin is a straightforward process when you have the correct files ready. Gather the right firmware file for the Samsung Galaxy M01 SM-M015F, the correct Odin version, and the steps that work.
Before starting, sign out of any active Samsung accounts. Knox security will trigger if you skip this, and fixing a KG lock later takes unnecessary time. Samsung firmware packages also use the .tar.md5 format. Once you extract the ZIP, look for files labeled AP_*, BL_*, CP_*, and CSC_* (or HOME_CSC_*). If these files are missing, the package is incorrect.
The Samsung Galaxy M01 SM-M015F firmware downloads as a compressed ZIP archive. Use WinRAR or 7-Zip to extract the contents. Inside, you will find the standard Odin files like AP_*.tar.md5, BL_*.tar.md5, CP_*.tar.md5, and CSC_*.tar.md5 (or HOME_CSC_*.tar.md5). Missing these files means you downloaded the wrong package for your phone.
Flashing stock firmware intentionally wipes all data to resolve software problems like FRP locks, app crashes, sluggish performance, forgotten patterns, logo freezing, connectivity bugs, battery drain, and soft bricks.
Hard Reset Samsung Galaxy M01 SM-M015F
You can factory reset the Samsung Galaxy M01 SM-M015F without a computer by powering it off and holding Volume Up + Power until the recovery menu appears. Use the volume keys to highlight “Wipe Data/Factory Reset” and press the Power button to confirm. On older models with a Home button, use Volume Up + Home + Power.
A hard reset wipes your data and returns the Samsung Galaxy M01 SM-M015F to its factory state. This resolves standard software glitches like slow performance, app errors, forgotten locks, and bootloops. If problems remain after the reset, a complete firmware flash using Odin is the next step.
Samsung Galaxy M01 SM-M015F FRP Bypass
The most effective method to bypass FRP on the Samsung Galaxy M01 SM-M015F involves using a free Android apps launcher to access settings during the initial setup. After a factory reset or flash, a Google account lock (FRP) might appear. Our free Android apps launcher provides quick access to bypass this screen. Removing your Google account before flashing prevents this issue entirely.
Why Do We Need Samsung Galaxy M01 SM-M015F Firmware?
Flashing the official firmware resolves severe software issues and restores the operating system on the Samsung Galaxy M01 SM-M015F. Samsung devices use Odin for flashing, regardless of the internal chipset. Whether you face a boot failure or a system error, installing the official software can fix it:
- Unlock a disabled or locked phone.
- Upgrade to the newest Android version supported by the hardware.
- Repair freezing, lagging, and startup loops on your SM-M015F Galaxy M01.
- Fix battery drain and failed OTA updates.
- Reinstall the original stock ROM to maintain warranty status.
- Fix a device that only boots into recovery mode.
- Recover from Knox or KG lock issues caused by an interrupted or incorrect flash.

Choosing the Right Firmware Version
Confirming you have the correct firmware version is essential before flashing to avoid permanent damage to your device. Flashing the wrong file is a critical mistake:
- Identify Your Exact Model Number: Open Settings › About Phone and check your full model number (e.g. SM-M015F). The letter suffix indicates the region, U/U1 = USA, W = Canada, N = Korea, B/F = International/Global. Installing firmware for a different variant causes errors.
- Match the CSC (Region): The firmware filename includes a 3-letter region code that must match your phone. Verify your current CSC under Settings › About Phone › Software Information or check the Service Provider line in Download Mode. Common codes include XAA (US), BTU (UK), INS (India), and SER (Russia).
- Check the Binary Level: Review the version string in your current software (e.g.
XXU9BZDP, the digit after the letters represents the binary level). You cannot downgrade past this level. A device on Binary 9 only accepts Binary 9 or newer firmware. - Confirm the Build Date: The final 4 characters of the PDA version indicate 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: Turn off the phone, then hold Volume Down + Power to open Download Mode. This screen displays your exact model, CSC, and software version for verification.

Which Firmware Version Should I Download?
The correct firmware version depends entirely on the specific issue you are trying to fix on your device. I receive this question frequently in the comments, 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 | XXU2ATJ1, download this one. It is the latest Samsung Galaxy M01 SM-M015F 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 XXS2ATG1, 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 XXU2ATJ1 first, then follow the IMEI repair guide. Do not skip the reflash. |
| XXU2ATJ1 failed with a flash error | Try XXS2ATG1 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 | XXU2ATJ1, 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.

Prerequisites for Samsung Galaxy M01 SM-M015F Firmware
Preparing your computer and phone correctly prevents common flashing errors with the Samsung Galaxy M01 SM-M015F firmware. Two issues frequently disrupt Samsung flashes: failing to sign out of Samsung accounts (which triggers KG lock) and using a low-quality USB cable that drops the connection. Always use a proper data cable for this process.
- Back Up IMEI Numbers: Dial *#06# and write down both IMEI numbers. Keep these safe in case you need to restore your IMEI later.
- Remove Google Accounts: Sign out of all Google accounts to prevent an FRP lock after the flash.
- Remove Samsung Accounts: Sign out of all Samsung accounts to avoid triggering KG lock.
- Back Up Your Data: Save your photos, contacts, WhatsApp chats, and important files. Flashing completely wipes the phone.
- Charge Your Device: Ensure the battery is at least 50%. A power loss during a flash is difficult to recover from.
- USB Cable & PC: Use a reliable data USB cable and a Windows computer with open USB ports.
- Install Required Drivers:
How to Install Firmware on Samsung Galaxy M01 SM-M015F
Installing the firmware requires Odin and careful attention to the file loading process. Keep “Auto Reboot” and “F. Reset Time” checked in Odin to ensure a clean installation. If you need help selecting an Odin version, visit our Odin versions page. Certain older Samsung phones perform better with specific Odin builds.
- Download and Extract:
- Get the correct firmware package from the download section.
- Extract the ZIP file to a simple folder path. Avoid folders with spaces or special characters, as flash tools sometimes fail to read them.
- Install the Listed Drivers:
- Ensure all drivers listed above are installed, and restart your PC. Skipping the restart often causes driver recognition failures.
- Load the Firmware File:
- In Odin, click “BL” and select the BL_*.tar.md5 file. Click “AP” and select the AP_*.tar.md5 file. Do the same for “CP” and “CSC”. Choose HOME_CSC to keep your data, or CSC for a complete wipe.
- Connect Your Device:
- Enter Download Mode: Turn off the phone, then hold Volume Down + Power (add the Home button on older models) until the warning screen appears. Press Volume Up to confirm.
- Connect the phone to your PC via USB. Odin should display “Added..” in the log area, confirming a successful connection.
- Start Flashing:
- Click the “Start” button.
- Leave the device completely alone until the process finishes. Moving the cable or disconnecting mid-flash will brick the phone.
- Wait and Reboot:
- Disconnect the device once Odin shows a successful completion.
- Power on the phone. The initial boot takes longer than usual, often up to 8 minutes.

What to Expect After Flashing Samsung Galaxy M01 SM-M015F Firmware
A successful Samsung Galaxy M01 SM-M015F firmware flash will cause the device to behave differently for the first few minutes. Many users assume something went wrong when the phone is actually working as expected. Here is what is completely normal:
- How to know the flash was successful: Odin will display “PASS.” in green text in the top-left log area. Seeing this means the installation finished properly.
- First boot takes 3 to 8 minutes, allow the device time to configure the operating system. Forcing a restart during this phase can cause a bootloop.
- The phone will feel warm during first boot, this heat is normal and will subside once the initial setup finishes.
- All your apps are gone, this is standard for a factory reset. Reinstall them via the Play Store. A previous Google backup might offer to restore them automatically.
- Dial *#06# immediately after setup to verify your IMEI. Do this before inserting a SIM card. If the screen displays “unknown” or “null”, follow the IMEI repair guide below immediately.
- Be careful when re-adding your Google account, an FRP prompt might appear if the account was not removed prior to flashing. Enter your credentials during the setup wizard rather than through the Settings menu.
- Wi-Fi, Bluetooth, and mobile data should function right away. If mobile data fails, navigate to Settings › SIM and Network and manually input your APN details, as the flash sometimes clears carrier settings.
- Stuck in a bootloop after first boot? Access recovery mode and execute a factory reset, refer to the hard reset guide above. This clears leftover data conflicts and does not indicate a bad firmware file.
- Samsung Smart Switch: Following the installation of the Samsung Galaxy M01 SM-M015F firmware, Smart Switch might suggest extra updates. Allow it to install them to guarantee your phone has the newest regional security patches.
Missing IMEI or Corrupt Baseband on Samsung Galaxy M01 SM-M015F After Flashing?
A missing IMEI after flashing usually indicates a corrupted EFS partition, which stores your carrier settings and IMEI data. Restoring an IMEI that does not belong to your original device is illegal in most regions, so only perform this repair to restore your original number. Software like ChimeraTool or BFT can assist with this process. Verify your local regulations before proceeding.

Common Issues When Flashing Samsung Galaxy M01 SM-M015F
- Odin Shows “FAIL” Instead of “PASS”:
- This typically happens when the firmware region or model does not match the phone. Verify your exact model number in Settings › About Phone before proceeding. Even a single letter difference matters.
- Samsung Galaxy M01 SM-M015F Not Recognized by Odin:
- Install the Samsung USB drivers again, ensure the phone is in Download Mode, and try a different USB cable. Odin requires a stable data connection.
- KG Lock / Knox Triggered After Flashing:
- This occurs when a Samsung account remains signed in prior to flashing, or if unofficial software was installed. Always sign out of accounts beforehand. Resolving an active KG lock usually requires a professional unlocking tool.
- Boot Loop After Flashing:
- Open recovery mode (Volume Up + Power) and perform a factory reset. This wipes conflicting data left behind by the previous operating system.
