FRP (Factory Reset Protection) is a security feature added by Google on Android devices running Android 5.1 and above. When a Samsung device is reset without removing the Google account, it asks for the original account credentials to verify identity. If you’ve forgotten your Google login or purchased a second-hand device, this can be a serious roadblock.
In this post, you’ll learn how to bypass the Google account lock on all Samsung devices using Odin and special firmware files—without using paid software.
Notice: This method is for educational and service purposes only. You must have authorization to unlock the device. Bypassing FRP on someone else’s phone without permission is illegal.
What is FRP (Factory Reset Protection)?
FRP is automatically enabled when you add a Google account to an Android phone. If the device is factory reset without removing the Google account, it locks the setup process until the original credentials are entered.
Tools Needed to Remove FRP via Odin
To begin, make sure you have the following:
| Tool | Description |
|---|---|
| Odin Tool | Samsung flashing tool for Windows |
| Samsung USB Drivers | Required for proper device detection |
| Combination File | A special firmware to enable developer settings |
| Full Stock Firmware | Used to restore normal system after bypass |
| FRP Bypass Tool (optional) | Final step if needed after flashing |
Step 1: Download Required Files
Samsung USB Drivers
Install these first: Samsung Drivers Download
Odin Tool
Use Odin v3.14.4 or newer. Get it from a trusted source like SamMobile or XDA.
Combination Firmware
Search for your model and binary version (e.g., SM-A205F U3). Download from:
-
samsungcombination.com
Stock Firmware
Download the official firmware . Make sure the binary/version matches the combination file.
Step 2: Flash the Combination File Using Odin
-
Boot your phone into Download Mode:
-
Turn off the device.
-
Press Volume Down + Bixby + Power or Volume Down + Volume Up (varies by model).
-
Connect the phone to the PC via USB.
-
-
Launch Odin and load the combination file into the AP slot.
-
Click Start. Wait for the process to complete. Your phone will now boot into test/service mode.
Step 3: Enable Developer Options
-
In the combination firmware, go to Settings > Developer Options.
-
Enable USB Debugging and OEM Unlocking (if available).
Step 4: Flash Stock Firmware (Restore System)
-
Reboot into Download Mode again.
-
In Odin, load the stock firmware:
-
BL, AP, CP, and CSC files (not HOME_CSC).
-
-
Click Start to flash. Once complete, the device will reboot into normal mode.
Step 5: FRP Should Be Removed
In most cases, if OEM Unlocking was enabled and the flash was successful:
-
The phone will skip the Google verification screen.
-
You can now set it up as new.
If it still asks for the Google account:
-
Use a Samsung FRP Tool via USB to bypass the setup screen (tools like SamFirm FRP Tool, Easy Samsung FRP, or Alliance Shield X with ADB method).
Supported Samsung Models
This method works on most Samsung devices including:
-
Galaxy A series (A10, A12, A20, A50, etc.)
-
Galaxy M series (M10, M11, M21, etc.)
-
Galaxy S series (S8, S9, S10, S20, etc.)
-
Galaxy Note series
-
Galaxy Tab series
Tips & Warnings
-
Always match the binary version of firmware and combination file (e.g., A305F U3).
-
This process may void warranty or trigger Knox (especially on newer models).
-
Use only on devices you own or have permission to unlock.
Conclusion
Using Odin and combination firmware is a powerful method to bypass Google account lock (FRP) on Samsung phones. It’s a technician-level method that doesn’t require expensive tools—just the right files, some patience, and attention to detail.
