Samsung Galaxy On5 SM-G5528 Firmware (Flash File) Drivers, Tools & Guide
Flashing Samsung firmware with Odin is a straightforward process if you follow the steps correctly. This page contains the correct Samsung Galaxy On5 SM-G5528 firmware file, the appropriate Odin version, and the steps that work. Sign out of your Samsung account before starting to prevent Knox locks from triggering later. Also, verify that your extracted files are named AP_*, BL_*, CP_*, and CSC_*. If you see a single file instead, you have the wrong package.
Currently, only one firmware build is available for the Samsung Galaxy On5 SM-G5528. This is the stock ROM you should use for recovery, unbricking, or FRP bypass. Powered by a Qualcomm Snapdragon 430 (msm8937) processor, the Samsung Galaxy On5 SM-G5528 requires Qualcomm Flash Image Loader (QFIL) and Qualcomm HS-USB drivers. Make sure to install the correct driver package before connecting your device. The stock firmware ships with Android 6.0.1 Marshmallow, which determines the default apps, security features, and interface you will see after flashing.
The files here come from verified repositories and have been checked for integrity before being listed on this page. Samsung firmware uses a multi-file system (AP, BL, CP, CSC) specific to Odin-based flashing, which differs from single-file scatter-based tools.
Your Samsung Galaxy On5 SM-G5528 firmware comes as a compressed ZIP file. Download and extract it using WinRAR or 7-Zip. After extracting, you should see files named like AP_*.tar.md5, BL_*.tar.md5, CP_*.tar.md5, and CSC_*.tar.md5 (or HOME_CSC_*.tar.md5). If you do not see these files, you may have the wrong firmware package for your device.
Keep in mind that flashing stock firmware erases all data, which is intentional, as it resolves software issues including FRP lock, app problems, slow performance, forgotten pattern locks, a dead or logo-stuck device, Wi-Fi and Bluetooth issues, battery drain, and soft brick situations.
How to Wipe Samsung Galaxy On5 SM-G5528 to Factory Settings
To factory reset Samsung Galaxy On5 SM-G5528 without a computer, power off the device completely, then hold Volume Up + Power (for older models with a Home button, use Volume Up + Home + Power) at the same time until the recovery menu appears. Use the volume keys to navigate to “Wipe Data/Factory Reset” and confirm with the Power button.
A hard reset erases all data and restores Samsung Galaxy On5 SM-G5528 to its original factory state. This fixes most software problems, slow performance, app crashes, forgotten screen locks, and bootloops. If the issue persists after a factory reset, a full firmware flash using Odin is covered in the following sections.
Samsung Galaxy On5 SM-G5528 Google Account Bypass After Reset
The fastest way to bypass FRP on Samsung Galaxy On5 SM-G5528 is to use a free Android apps launcher that lets you access settings during the setup wizard. After flashing or performing a factory reset you may see a Google account lock (FRP). Our free Android apps launcher is the fastest way to get past it. This is also why I always recommend removing your Google account before flashing, it avoids this problem entirely.
What Samsung Galaxy On5 SM-G5528 Firmware Fixes

Verify Your Samsung Galaxy On5 SM-G5528 Model Before Downloading
The single biggest mistake people make is flashing firmware meant for a different variant. Before downloading anything, verify your exact device identity:
- Identify Your Exact Model Number: Go to Settings › About Phone and note your full model number (e.g. SM-G5528). The letter suffix matters, U/U1 = USA, W = Canada, N = Korea, B/F = International/Global. Flashing firmware built for a different variant can cause issues.
- Match the CSC (Region): The 3-letter region code in the firmware filename must match your device. Check Settings › About Phone › Software Information for your current CSC, or look at the Service Provider line in Download Mode. Common codes: XAA (US), BTU (UK), INS (India), SER (Russia).
- Check the Binary Level: Look at the version string in your current firmware (e.g.
XXU9BZDP, the number after the letters is the binary level). You cannot downgrade to a lower binary level. If your device is on Binary 9, only flash Binary 9 or higher firmware. - Confirm the Build Date: The last 4 characters of the PDA version encode the build date, first character is the year (A=2024, B=2025, C=2026), second is the month (A=Jan through L=Dec).
- Verify in Download Mode: Power off, hold Volume Down + Power to enter Download Mode. This screen shows your exact model, CSC, and current firmware version, use this to confirm before flashing.

Which Firmware Version Should I Download?
This is the question I get asked most often in the comments, so I put together a simple guide. Find your situation in the table and go straight to the right file:
| Your Situation | What I Recommend |
|---|---|
| Phone is completely dead or stuck on logo | MU1AQH1, download this one. It is the latest Samsung Galaxy On5 SM-G5528 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 the next older version, 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 MU1AQH1 first, then follow the IMEI repair guide. Do not skip the reflash. |
| MU1AQH1 failed with a flash error | Try the next older version 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 | MU1AQH1, 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.

Important: The Samsung Galaxy On5 SM-G5528 (SM-G5528) should not be confused with other Galaxy On5 variants that may have different chipsets or regional firmware. Even devices in the same Galaxy On5 line can use completely different processors. Always verify your exact model code “SM-G5528” in Settings > About Phone before downloading any firmware from this page.
- Your model number is a variant of SM-G5528 with a different letter suffix. Check About Phone carefully, one letter difference can cause a failed or broken flash.
- Your chipset differs from Qualcomm Snapdragon 430 (msm8937). 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.
What You Need Before Flashing Samsung Galaxy On5 SM-G5528
Go through this list before you open Odin for the Samsung Galaxy On5 SM-G5528. Two things that commonly cause problems with Samsung devices: a Samsung account that was not signed out before flashing, which can trigger KG lock, and a USB cable that works for charging but drops the connection mid-flash. Always use a proper data cable, not a charge-only cable.
- IMEI Backup: Open the dialer and enter *#06#. Write both IMEI numbers down on paper or take a screenshot. If you ever need to repair your IMEI after flashing, these are essential.
- Remove All Google Accounts: Go to Settings, Accounts, and sign out of every Google account on the device. Leaving accounts signed in triggers FRP lock after a flash, which blocks you from setting up the phone.
- Remove Samsung Accounts: Sign out of all Samsung accounts to avoid KG lock.
- Backup Everything: Photos, contacts, messages, WhatsApp data, move it all to a computer or cloud service. The flash will restore the phone to factory state with nothing on it.
- 50% Battery Minimum: Do not start with a low battery. If power cuts out during the flash, the device can become unresponsive and much harder to fix.
- USB Cable and Computer: Use a proper data-transfer USB cable and a Windows PC. Avoid USB hubs, connect directly to the motherboard port for a stable connection.
- Download and Install Drivers:
Step-by-Step: Flash Samsung Galaxy On5 SM-G5528 Stock ROM
We are using Odin for this. A quick tip: keep “Auto Reboot” and “F. Reset Time” both checked in Odin, those two options together give you the cleanest flash result. If you are not sure which Odin version to use, check our Odin versions page. Some older Samsung devices work better with older Odin builds.
- Get the Firmware Ready:
- Download the firmware file from the download section above.
- Right-click the ZIP and select “Extract Here” or use 7-Zip. Put the extracted files in a folder without spaces in the name, like
C:firmware.
- Verify Your Drivers:
- Make sure the required drivers are installed. After installing, restart your PC, drivers often do not activate until after a reboot.
- Load the Firmware File:
- In Odin, click “BL” and select the BL_*.tar.md5 file. Click “AP” and select the AP_*.tar.md5 file. Repeat for “CP” and “CSC”. Use HOME_CSC to keep data, or CSC for a clean flash.
- Connect Your Device:
- Enter Download Mode: Turn off your phone, then hold Volume Down + Power (add Home button on older models) until the warning screen appears. Press Volume Up to confirm and enter Download Mode.
- Connect your phone to your PC via USB. Odin should show “Added..” in the log area, this means your device is detected.
- Start Flashing:
- Hit the “Start” button in the flash tool to start the process.
- Leave the phone and cable completely alone until it finishes. Any interruption during this stage risks corrupting the flash.
- Wait and Reboot:
- When the flash completes, unplug the USB cable from your phone.
- Turn on the device. First boot takes 3 to 8 minutes, do not force restart it during this time.

Post-Flash Behavior on Samsung Galaxy On5 SM-G5528
Here is what is completely normal after a successful flash:
- How to know the flash was successful: Odin will show “PASS.” in green text at the top-left of the log area. If you see this, everything went fine.
- Battery percentage may seem inaccurate for the first day. The battery statistics are calibrated during normal use. Charge the phone fully once without interruption and the readings will stabilize.
- Be careful when re-adding your Google account, if you did not remove it before flashing, you may see an FRP prompt. Add it fresh during the setup wizard, not afterwards through Settings.
- Fingerprint and face unlock data are erased during the flash. You will need to re-register your fingerprints and face data from scratch in the security settings.
- All your apps are gone, this is expected. Reinstall them from the Play Store. If you had a Google account backup active, it will offer to restore your apps automatically during setup.
- The phone may ask for language and region again, this is normal after a flash. You are starting from a clean state, so the setup wizard runs just like when the phone was brand new.
- The phone will feel warm during first boot, this is normal. It settles after a few minutes once the initial app setup is complete.
Troubleshooting Samsung Galaxy On5 SM-G5528 Flash Errors
- Odin Shows “FAIL” Instead of “PASS”:
- This is usually a mismatch between the firmware region or model and your device. Confirm your exact model number in Settings › About Phone before selecting the firmware. Even a single letter difference in the model code matters.
- Samsung Galaxy On5 SM-G5528 Not Recognized by Odin:
- Reinstall the Samsung USB drivers. Make sure you are in Download Mode. Try a different USB cable, Odin can be sensitive to cable quality.
- KG Lock / Knox Triggered After Flashing:
- This happens when a Samsung account was still signed in before flashing, or when unofficial firmware was used. Always sign out of Samsung accounts before flashing. If KG lock is already active, a professional unlocking tool is generally needed.
- Boot Loop After Flashing:
- Enter recovery mode (Volume Up + Power) and perform a factory reset. This clears any leftover data from the previous firmware that may be causing the conflict.
Missing IMEI or Corrupt Baseband on Samsung Galaxy On5 SM-G5528 After Flashing?
A missing IMEI on a Samsung device after flashing usually points to a corrupted EFS partition, this is the partition that stores your IMEI and carrier settings. Note that restoring an IMEI that is not your original number is illegal in most countries, so only do this if you are restoring the number the device had before you flashed. Tools like ChimeraTool or BFT can help with this. Check your local laws before proceeding.

Frequently Asked Questions
Q1: Can I go back to an older firmware version?
A: It is technically possible on some Qualcomm builds, but downgrading can cause security issues and app compatibility problems. If the latest version is causing trouble, leave a comment below, there is usually a better fix than rolling back.
Q2: What should I do if I encounter an FRP lock after flashing?
A: Use our free Android apps launcher. FRP lock activates when a Google account was still signed in before flashing. This is why signing out of your Google account before flashing avoids this issue entirely.
Q3: How long does the flashing process take?
A: The actual flash usually takes between 3 and 10 minutes depending on the firmware size and USB connection speed. The first boot after flashing takes another 3 to 8 minutes. Do not interrupt the device during either stage. If the progress bar in Odin appears stuck, give it a few more minutes before assuming something went wrong.
Q4: How do I enter recovery mode?
A: Power the device off completely, then hold Volume Up + Power at the same time until the recovery menu appears. For older Samsung models with a physical Home button, use Volume Up + Home + Power. The recovery menu displays the build number which you can use to verify your firmware version before flashing.
Q5: Do I need an internet connection during flashing?
A: No. The flashing process is entirely offline, it happens between your PC and the phone via the USB cable. You do not need internet at any point during the flash itself. You will need internet later to set up the phone and download your apps.
Q6: My device is not detected by Odin. What should I do?
A: Start with the drivers, reinstall the Samsung USB drivers, restart your PC, then try again. Switch to a USB 2.0 port if you are on USB 3.0. Disable your antivirus temporarily. If none of that works, leave a comment with the exact error message.
Q7: Can I flash this firmware if my phone does not turn on at all?
A: Yes, in most cases. Samsung devices can usually enter Download Mode even when the screen is completely dead, hold Volume Down + Power for 10 seconds. If the battery is completely drained, charge it for at least 15 minutes first.
Q8: Will flashing erase my data?
A: Yes, flashing with Odin restores the device to factory state, including Android 6.0.1 Marshmallow default settings. All apps, photos, contacts, and accounts will be removed. Back up everything you need before you start. There is no way to recover data once the flash is complete.
