Samsung Galaxy Grand 3 SM-G7200 Firmware (Flash File) Drivers, Tools & Guide
Flashing Samsung firmware with Odin is a reliable process once you have the correct files and drivers. I have put everything together on this page: the right firmware file for the Samsung Galaxy Grand 3 SM-G7200, the correct Odin version, and the steps that work.
One thing to do before you start: if your device has a Samsung account signed in, sign it out before doing anything else. Knox will trigger if this step is skipped, and dealing with a KG lock after flashing takes extra time. Also, Samsung firmware comes in .tar.md5 format, after extracting the ZIP, you should see files named AP_*, BL_*, CP_*, and CSC_* (or HOME_CSC_*). If you do not see these, you have the wrong package.
Only one firmware build is currently available for the Samsung Galaxy Grand 3 SM-G7200. This is the stock ROM you should use for recovery, unbricking, or FRP bypass. Powered by a Qualcomm MSM8916 Snapdragon 410 processor, the Samsung Galaxy Grand 3 SM-G7200 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 4.4.4 (KitKat), which determines the default apps, security features, and interface you will see after flashing.
This firmware was sourced directly from verified repositories and 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 Grand 3 SM-G7200 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.
Once you flash, the device goes back to factory condition. Everything stored on the phone, photos, messages, apps, will be gone. This clean state is what allows the flash to fix stuck logos, FRP locks, software corruption, and performance issues.
Remove FRP Lock on Samsung Galaxy Grand 3 SM-G7200
The quickest method to bypass the FRP lock on the Samsung Galaxy Grand 3 SM-G7200 involves using an Android apps launcher during the setup process. 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.
Hard Reset Samsung Galaxy Grand 3 SM-G7200
To perform a factory reset on the Samsung Galaxy Grand 3 SM-G7200 without a computer, you must use a specific key combination. 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 Grand 3 SM-G7200 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.
Verify Your Samsung Galaxy Grand 3 SM-G7200 Model Before Downloading
Verifying your exact model number before downloading firmware is the most important step to avoid bricking your device. The single biggest mistake people make is flashing firmware meant for a different variant. Before downloading anything, confirm your device identity:
- Identify Your Exact Model Number: Go to Settings › About Phone and note your full model number (e.g. SM-G7200). 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.
Common Reasons to Reinstall Samsung Galaxy Grand 3 SM-G7200 Firmware
Samsung devices like the Samsung Galaxy Grand 3 SM-G7200 are best repaired by reinstalling the original stock ROM. Whether you are dealing with a boot issue or a software problem, flashing the official firmware can resolve it:

Which Firmware Version Should I Download?
Choosing the right firmware version depends on your specific device situation. 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 | CU1AOH2, download this one. It is the latest Samsung Galaxy Grand 3 SM-G7200 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 CU1AOH2 first, then follow the IMEI repair guide. Do not skip the reflash. |
| CU1AOH2 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 | CU1AOH2, 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 Grand 3 SM-G7200 (SM-G7200) should not be confused with other Galaxy Grand 3 variants that may have different chipsets or regional firmware. Even devices in the same Galaxy Grand 3 line can use completely different processors. Always verify your exact model code “SM-G7200” in Settings > About Phone before downloading any firmware from this page.
- The model code on your phone must match SM-G7200 exactly. Even a single letter variant (like adding or dropping an “i” or “s”) can mean a different chipset inside.
- Your chipset should be Qualcomm MSM8916 Snapdragon 410. Recovery mode shows this information if you are not sure.
- Do not mix firmware from other download sites with the files on this page.
- If the downloaded file is much smaller than what is listed in the table above, re-download it, partial files will fail.
What You Need Before Flashing Samsung Galaxy Grand 3 SM-G7200
Go through this list before you open Odin for the Samsung Galaxy Grand 3 SM-G7200. 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.
- Write Down Your IMEI: Open your phone dialer and type *#06#. Take a photo of the screen showing both IMEI numbers. You may need these later to fix your IMEI if it gets wiped during the flash.
- Sign Out of Google: Open Settings, go to Accounts, and remove every Google account from the device. If you skip this, Google will lock the phone after flashing and you will need to do an FRP bypass.
- Remove Samsung Accounts: Sign out of all Samsung accounts to avoid KG lock.
- Save Your Files: Copy everything important to a PC or cloud storage. After flashing, the phone will be completely empty, no apps, no photos, no messages.
- Battery Check: Charge to at least 50%. If the phone dies during flashing, you could end up with a device that will not turn on at all.
- Get the Right Cable: You need a USB data cable, the kind that can transfer files, not just charge. Plug it into a USB 2.0 port on a Windows PC for the most reliable connection.
- Set Up Drivers:
Flashing Samsung Galaxy Grand 3 SM-G7200 Firmware With Odin
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.
- Download and Unpack:
- Pick the correct firmware version from the downloads above and save it to your PC.
- Extract the ZIP file. If the extracted folder contains another ZIP inside, extract that one too. You should end up with the actual firmware files, not another archive.
- Driver Check:
- Double-check that you have installed the required drivers. A missing driver is the most common reason the flash tool cannot detect your phone. Reboot your PC after installing.
- 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:
- Start the flash by clicking “Start”.
- Leave everything untouched until completion. Even bumping the USB cable can interrupt the write and cause a failed flash.
- Wait and Reboot:
- The flash is complete when the tool shows a success indicator. Disconnect your phone.
- Turn the phone on. Do not worry if it sits on the boot logo for several minutes, the system is rebuilding itself from scratch.

Troubleshooting Samsung Galaxy Grand 3 SM-G7200 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 Grand 3 SM-G7200 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.
After Flashing: What Happens Next on Samsung Galaxy Grand 3 SM-G7200
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.
- Wi-Fi, Bluetooth, and mobile data should all work right after setup. If mobile data is not connecting, go to Settings, SIM and Network, and re-enter your APN manually, the flash sometimes clears carrier APN settings.
- Dial *#06# immediately after setup to check your IMEI. Do this before you insert a SIM card. If it shows “unknown” or “null”, follow the IMEI repair guide below before doing anything else.
- 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.
- 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.
- 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.
Missing IMEI or Corrupt Baseband on Samsung Galaxy Grand 3 SM-G7200 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.

Samsung Galaxy Grand 3 SM-G7200 Flashing FAQ
Q1: Is this firmware compatible with other Samsung models?
A: No. This firmware is built specifically for the Samsung Galaxy Grand 3 SM-G7200 running on the Qualcomm MSM8916 Snapdragon 410 chipset. Even variants of the Galaxy Grand 3 with a different letter suffix can have a completely different chipset inside. Flashing the wrong firmware can leave your phone in a state that is very difficult to recover from. Always check your exact model number in Settings.
Q2: 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.
Q3: Will flashing void my warranty?
A: Flashing official stock firmware generally does not void your warranty since you are restoring the device to its factory-intended state. However, some manufacturers may flag that the bootloader was unlocked or that the flash counter increased. Check your specific warranty terms with Samsung support if you are concerned.
Q4: 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.
Q5: 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.
Q6: Can I use a Mac or Linux computer for this?
A: Samsung firmware can be flashed using Heimdall on Linux or Mac, but the instructions on this page are written for Odin on Windows. If you only have a Mac, you may want to use a Windows virtual machine or Boot Camp for the most straightforward experience.
Q7: My IMEI shows “unknown” after flashing. Is my phone permanently damaged?
A: No, it looks alarming, but it is fixable. Follow the IMEI repair guide in the troubleshooting section above. For Samsung devices, check for EFS partition corruption first. Do not insert a SIM card until the IMEI is restored.
Q8: Is it safe to flash during a power outage risk?
A: It is best to avoid flashing during unstable power conditions. If your PC shuts down during the flash, it can corrupt the write and leave the phone in an unbootable state. If you are in an area with unreliable power, use a laptop with a fully charged battery instead of a desktop.
