SamFw FRP Tool is a Windows-based software designed to remove FRP lock (Factory Reset Protection) on Samsung, Xiaomi and LG devices. It helps users unlock their phones when they forget the Google verification credentials after a factory reset.
Originally created for service technicians, SamFw FRP Tool has now become widely used by individual users who need a simple, one-click FRP bypass.
The software offers both free and paid unlocking modes depending on your device's security patch level:
🆓 Free unlocks work for older firmware (before December 2022)
💵 Paid service is required for newer patches (2023 and later)
FRP tools are intended for professional or authorized use only — such as when verifying legitimate ownership or repairing a device. The SamFw Tool is a legitimate version officially released by the SamFw developer team. It’s widely used by technicians for Samsung FRP removal. However, using it on someone else’s device may violate Google's or the manufacturer's terms of service. Always consult the device’s warranty or support before attempting any verification resets, and always download from the official SamFw domain or trusted sources.
The SamFw FRP Tool is primarily designed for Samsung smartphones and tablets, but some features also support other Android devices for general ADB operations.
| Brand/OS | Supported Functions |
| Samsung | FRP removal, firmware flashing, CSC change, network unlock, factory reset |
| LG | FRP removal, factory reset, flash firmware |
| Xiaomi | FRP removal, factory reset, Micloud reset |
| Other Android | Factory reset, APK installation, limited FRP removal |
If your Samsung device runs Android 14 or has the latest One UI 6+ patch, the free FRP bypass might fail — in that case, you can try the SamFw Paid Service or use EaseUS MobiUnlock for Android as a universal solution.
Yes — the SamFw FRP Tool offers free FRP removal for many older Samsung models. You can use the tool’s offline mode without paying for standard FRP unlocks.
However, Paid online services are required for newer devices or higher security levels (post-2023 patches). The tool's website lists "FRP Remove Paid Server" options (35–40 credits per unlock).
You can find the official SamFw FRP Tool information and updates on the developer's website. For safety, always verify the digital signature or checksum before installing any third-party diagnostic utility. It is compatible for Windows 7/8/10/11 (64-bit).
For more information about the v4.9 release of SamFw Tool, refer to SamFw v4.9 official blog.
Note that the old SamFw Tool version (like v4.7.1, v4.1, v3.2 and v2.7.1) has already removed from the official SamFw website for years, but some popular versions has been uploaded on Android File Host, a legal and safe Android file hosting plaform.
However, it's highly recommended to download the latest SamFw Tool v4.9 for better experience. Once you download the SamFw Tool zip file on your Windows PC, extract it, run the .exe file as Administrator for installation.
Free FRP removal works best on devices with security patches before December 2022.
Newer models (2023 and later) may require the paid online FRP service or an alternative tool.
🚨Important Note: This tool should only be used on devices you legally own or have authorization to service. Use on non-authorized devices may violate terms of device manufacturers or local laws.
Step 1. Prepare Your Device
Step 2. Connect and Launch
Step 3. Enter Test Mode for Unlocking
On your phone's Welcome screen, tap Emergency Call and dial *#0*# to enter Test Mode.
Make sure the device is connected to Wi-Fi or mobile network.
Select your connected Samsung device in the tool's device dropdown.
Step 4. Bypass FRP
Sometimes the SamFw tool may not function properly due to device compatibility or connection issues. Here are some common errors and how to fix them:
1. SamFw FRP Tool Enable ADB Failed
If you encounter the "Enable ADB Failed" error when using Samsung FRP Tool, the recommended solution is to enter Test Mode (access Emergency Call and tap *#0*#) on the device and try to activate ADB again. This mode allows the tool to access the necessary debugging options for FRP removal.
If the problem persists after retrying in test mode, consider switching to alternative Samsung FRP unlocking services such as MobiUnlock, ZeroKnox Removal Tool, or Easy Flashing. These tools offer different methods and better compatibility with newer devices and security updates, increasing your chances of successful FRP bypass.
2. 'SamFw Tool already running!' Error Message
When you encounter the issue where running SamFwTool directly from the zip file results in the message "SamFw Tool already running!," but you cannot find any running process in Task Manager, the solution is as follows:
Extract/Unzip the zip file first (do not run directly from zip).
Run the exe from the extracted folder.
If the message "SamFw Tool already running!" still appears, open Task Manager (press Ctrl + Shift + Esc) and locate the SamFw Tool process.
3. Windows Cannot Access the Specified Device, Path, or File Error
If you see the error "Windows cannot access the specified device, path, or file" while trying to run SamFw Tool, it often means Windows is blocking the program due to security or permission issues. How to fix it:

In fact, the SamFw FRP Tool is a useful option for technicians handling older Samsung models, it can be complex for regular users and may not work on the latest devices. And there are some users complaining about SamFw FRP Tool 'enable ADB failed' error and it failed to bypass Samsung FRP lock.
Therefore, here I'd like to recommend a great alternative to SamFw Tool. If you prefer a simpler, faster, and more reliable solution, EaseUS MobiUnlock for Android is your best choice.
Why Choose MobiUnlock?
This Samsung FRP tool stands out as a beginner-friendly FRP unlock tool that supports all Samsung devices and Android versions, including the latest Galaxy S24/S24 Ultra and devices running Android 6 or later.
Unlike SamFw, which requires technical setup, MobiUnlock offers a clean, guided interface — just follow the on-screen instructions, no complex ADB or manual steps needed.
It can bypass FRP in 10 minutes or less with a higher success rate, backed by 24/7 customer support and a 30-day money-back guarantee.
If your phone uses an older patch (before 2023), SamFw may work for free. But for newer devices (2023 or later), EaseUS MobiUnlock provides a faster, easier, and more reliable solution.

Q: Why do I need to install Samsung USB driver before I use SamFw FRP Tool?
Installing the Samsung USB driver is essential because it enables your PC to properly recognize and communicate with the Samsung device via USB. Without the correct driver, the computer may fail to detect the phone or interact with it during the FRP bypass process.
