If you need to fix your Samsung Galaxy S6 edge SM-G925S, installing the correct official firmware is often the solution. Here, you will find everything required: the firmware file, drivers, tools, and precise instructions to address issues like bootloops, FRP locks, and software glitches.
Device: Samsung Galaxy S6 edge SM-G925S | Chipset: Samsung Exynos 7 Octa 7420 | Flash Tool: Odin
Android: Android 5.0.2 (Lollipop), upgradable to 7.0 (Nougat), TouchWiz UI | File Type: .tar.md5 / ZIP (Contains AP, BL, CP, CSC files for Odin)
⚠ Warning: Flashing erases all data. Back up first.
Samsung Galaxy S6 edge SM-G925S Firmware (Flash File) Drivers, Tools & Guide
Getting Samsung devices updated or repaired with Odin usually goes smoothly when you have the right components. I compiled all the necessary items here: the proper firmware file for the Samsung Galaxy S6 edge SM-G925S, the correct Odin build, and clear instructions that get the job done.
Before starting, ensure any Samsung accounts are signed out of the device. Skipping this often activates Knox, leading to extra work with a KG lock after flashing. Samsung firmware files arrive in .tar.md5 format. After unzipping, expect to find files like AP_*, BL_*, CP_*, and CSC_* (or HOME_CSC_*). If your extracted archive does not contain these, you probably have an incorrect package.
The Samsung Galaxy S6 edge SM-G925S firmware you need comes as a ZIP archive. After downloading, extract its contents using a utility such as WinRAR or 7-Zip. Inside, you should find files like AP_*.tar.md5, BL_*.tar.md5, CP_*.tar.md5, and CSC_*.tar.md5 (or HOME_CSC_*.tar.md5). If these specific files are not present, it indicates you might have downloaded an unsuitable firmware package for your phone.
Understand that installing stock firmware wipes all data from the device. This is a deliberate part of the process, designed to fix various software issues like FRP locks, app malfunctions, sluggish performance, forgotten screen patterns, devices stuck on the logo or failing to boot, Wi-Fi and Bluetooth problems, rapid battery drain, and soft brick conditions.
Hard Reset Samsung Galaxy S6 edge SM-G925S
You can perform a factory reset on the Samsung Galaxy S6 edge SM-G925S without a computer by first powering it off completely. Then, simultaneously press and hold the Volume Up + Power buttons (for older models with a Home button, use Volume Up + Home + Power) until the recovery menu appears. Navigate to “Wipe Data/Factory Reset” using the volume keys, and select it with the Power button.
Executing a hard reset deletes all user data and returns the Samsung Galaxy S6 edge SM-G925S to its original factory settings. This action can resolve many software issues, including slow operation, application malfunctions, forgotten screen lock passcodes, and devices stuck in a boot loop. If the problem continues after a factory reset, a complete firmware flash with Odin, as detailed later in this guide, is the next step.
Samsung Galaxy S6 edge SM-G925S FRP Bypass
The quickest method to bypass FRP on a Samsung Galaxy S6 edge SM-G925S involves using a free Android applications launcher, which provides access to device settings during the initial setup process. A Google account lock (FRP) might appear after a flash or factory reset. Our free Android apps launcher provides a swift solution for this. I always advise removing your Google account before any flashing operation to prevent this issue from occurring.
Why Do We Need Samsung Galaxy S6 edge SM-G925S Firmware?
Samsung devices, including the Samsung Galaxy S6 edge SM-G925S, are typically flashed with Odin, irrespective of their internal chipset. If you are experiencing boot-related troubles or other software malfunctions, installing the official firmware often provides a solution:
- Restore access to a locked or disabled device.
- Install the most recent Android version available for your phone.
- Correct issues such as startup loops, system lag, and freezing on your SM-G925S Galaxy S6 edge.
- Address failed over-the-air (OTA) updates and problems with excessive battery consumption.
- Reinstall the original Samsung stock ROM to maintain warranty eligibility.
- Get your device working again if it only starts in recovery mode.
- Fix KG lock or other Knox-related problems that arise from an improper or interrupted flash on your device.

Choosing the Right Firmware Version
Before starting any flashing procedure, pause and confirm that you have the correct file. Installing unsuitable firmware can lead to significant problems that are hard to reverse:
- Confirm Your Exact Model Number: Navigate to Settings › About Phone and carefully record the complete model number, such as SM-G925S. The specific letter suffix is critical (U/U1 for USA, W for Canada, N for Korea, B/F for International/Global). Using firmware intended for a different variant can lead to operational problems.
- Verify the CSC (Region Code): 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 information displayed in Download Mode. Examples of common codes include XAA (US), BTU (UK), INS (India), and SER (Russia).
- Determine the Binary Level: Examine the version string of your existing firmware (for instance,
XXU9BZDP, where the number following the letters indicates the binary level). It is not possible to flash firmware with a lower binary level. If your phone is currently running on Binary 9, you should only install firmware that is Binary 9 or higher. - Review the Build Date: The final four characters of the PDA version string contain the build date information. The first of these characters represents the year (A=2024, B=2025, C=2026), and the second signifies the month (A=January through L=December).
- Cross-Check in Download Mode: Power down the device, then hold the Volume Down + Power buttons simultaneously to access Download Mode. This display presents your precise model number, CSC, and current firmware version, which you should use for final verification before starting the flash.

Which Firmware Version Should I Download?
This inquiry comes up frequently in the comments, so I created a straightforward guide to address it. Locate your specific scenario in the table below and proceed directly to the appropriate file:
| Your Situation | What I Recommend |
|---|---|
| If your phone is entirely unresponsive or remains stuck on the logo | G925SKSU3ERG1, download this one. It is the latest Samsung Galaxy S6 edge SM-G925S firmware available. |
| If you are only facing an FRP / Google account lock | See the FRP bypass guide above, you likely do not need the full firmware for this. |
| If you are uncertain about which region/CSC firmware 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. |
| If your phone is performing slowly 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. |
| If the IMEI is missing after a prior firmware flash | Re-flash G925SKSU3ERG1 first, then follow the IMEI repair guide. Do not skip the reflash. |
| If the G925SKSU3ERG1 firmware resulted in 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. |
| If you are restoring to factory settings or preparing for a warranty repair | G925SKSU3ERG1, clean state, fresh start. |
To identify a newer Samsung firmware version, examine the final four characters of the PDA string (e.g., S938BXXU9CZDP). The first character denotes the year (A=2024, B=2025, C=2026), the second represents the month (A=January, B=February… L=December, Z=final stable), and the last two indicate the revision (0-9 then A-Z, with Z being the highest). However, prior to comparing dates, always verify the binary level, which is the digit immediately preceding the date code (e.g., XXU9CZDP signifies Binary 9). It is not possible to 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 higher. Additionally, confirm that the three-letter CSC code within the firmware matches your device’s region.

Prerequisites for Samsung Galaxy S6 edge SM-G925S Firmware
Review this checklist carefully before launching Odin to work with your Samsung Galaxy S6 edge SM-G925S. Two frequent issues I encounter with Samsung devices are a Samsung account that was not signed out prior to flashing, which can activate KG lock, and using a USB cable that functions for charging but fails to maintain a stable connection during the flashing process. Always use a dedicated data cable, not one solely for charging.
- Record IMEI Numbers: Dial *#06# and securely write down both IMEI numbers. These are essential if you need to restore your IMEI after the flashing procedure.
- Disconnect Google Accounts: Log out of all Google accounts to prevent an FRP lock from activating after the flash.
- Disconnect Samsung Accounts: Ensure you are signed out of all Samsung accounts to avoid triggering a KG lock.
- Create a Data Backup: Make a complete backup of everything important, including photos, contacts, WhatsApp chats, and critical files. Flashing will completely erase the device.
- Ensure Sufficient Battery: Charge your device to at least 50%. A phone that loses power in the middle of a flash becomes significantly harder to recover.
- Prepare USB Cable and PC: Utilize a reliable data USB cable, distinct from a charge-only cable, and a Windows computer with functional USB ports.
- Install Necessary Drivers:
How to Install Firmware on Samsung Galaxy S6 edge SM-G925S
We will use Odin for this procedure. A helpful tip: keep both “Auto Reboot” and “F. Reset Time” selected in Odin. These two settings combined usually provide the most reliable flash. If you are uncertain about the correct Odin version, consult our Odin versions page, as some older Samsung devices perform better with earlier Odin releases.
- Acquire and Extract:
- Obtain the appropriate firmware package from the provided links.
- Extract the ZIP file to a straightforward directory path, avoiding spaces or special characters, as some flashing tools may encounter issues with such paths.
- Install Drivers:
- Ensure all drivers mentioned in the prerequisites section are installed and that your computer has been rebooted after their installation. Forgetting to restart is a frequent cause of driver malfunction.
- Prepare Firmware in Odin:
- Within Odin, click the “BL” button and select the BL_*.tar.md5 file. Then, click “AP” and choose the AP_*.tar.md5 file. Follow this pattern for “CP” and “CSC”. Use HOME_CSC if you wish to retain user data, or CSC for a complete, clean flash.
- Connect Phone:
- Enter Download Mode: Power off your phone completely. Then, hold down Volume Down + Power (also include the Home button for older models) until a warning screen appears. Press Volume Up to proceed into Download Mode.
- Connect your phone to your computer using the USB cable. Odin should display “Added..” in its log, indicating that your device is recognized.
- Begin Flashing:
- Click the “Start” button to initiate the process.
- Avoid disconnecting, moving the cable, or touching the device until the operation has completely finished. Interrupting a flash in progress is a common way to brick a phone.

What to Expect After Flashing Samsung Galaxy S6 edge SM-G925S Firmware
Many people comment, thinking something went wrong when it was actually a normal part of the process. Here is what you should consider entirely normal after successfully flashing Samsung Galaxy S6 edge SM-G925S firmware:
- Confirmation of success: Odin will display “PASS.” in green text within the log window. If you see this message, the procedure completed without issues.
- The initial boot cycle takes between three and eight minutes, do not prematurely restart the device. The operating system is configuring itself anew. Interrupting this stage frequently leads to boot loops.
- Expect the phone to feel warm during its first boot-up, this is normal and will subside after a few minutes once the initial application setup concludes.
- All your applications will be absent, which is the expected outcome. Reinstall them from the Play Store. If a Google account backup was active, the setup wizard will offer to automatically restore your applications.
- Immediately after completing the setup, dial *#06# to verify your IMEI. Perform this step before inserting any SIM card. If the IMEI appears as “unknown” or “null”, consult the IMEI repair guide below before taking any further action.
- Exercise caution when re-adding your Google account, if it was not removed before flashing, you might encounter an FRP prompt. Add the account afresh during the initial setup wizard, rather than later through the Settings menu.
- Wi-Fi, Bluetooth, and mobile data should function correctly immediately after setup. If mobile data fails to connect, navigate to Settings › SIM and Network and manually re-enter your APN details, as the flashing process can occasionally clear carrier APN configurations.
- If your device is stuck in a bootloop after the first boot, enter recovery mode and perform a factory reset from there; refer to the hard reset guide above. This can occur sometimes and does not indicate incorrect firmware but rather a conflict with residual data from the previous installation.
- Samsung Smart Switch: Following the flashing of your Samsung Galaxy S6 edge SM-G925S firmware, Samsung Smart Switch might suggest installing further updates. Allow these to complete; doing so ensures your device receives the most recent security patches for your geographical area.
Missing IMEI or Corrupt Baseband on Samsung Galaxy S6 edge SM-G925S After Flashing?
When a Samsung device shows a missing IMEI after flashing, it typically suggests damage to the EFS partition, which is responsible for storing your IMEI and network settings. It is important to remember that restoring an IMEI number that does not belong to your device is illegal in many jurisdictions. Therefore, only proceed if you are recovering the original IMEI that the device had before you performed the flash. Tools such as ChimeraTool or BFT can assist with this process. Always verify your local regulations before taking any action.
