King Tool Samsung FRP is a free Windows based tool developed by A.K Sumon that removes Google account verification on Samsung devices without credits, subscriptions or server authentication. It works through Alliance Shield, a Knox based bypass component that gives the tool access to Samsung’s device management layer without requiring a paid dongle or online license. This guide covers everything about King Tool in 2026, what it does, which devices and Android versions it actually works on, how to install it, how to use the Alliance Shield bypass method step by step, and what to do if it doesn’t work on your specific device.

The tools and methods on this page are for educational and informational purposes only. Only use them on devices you personally own or have been given explicit permission to work on. Bypassing FRP on a device you don’t own is illegal and can result in serious legal consequences. Always comply with Google’s terms of service and Samsung’s device policies. Rise ROM does not support any unauthorized or illegal use of the tools shared here.
Android Version and Firmware Reality Check
Before downloading anything know this upfront because most guides don’t say it clearly. King Tool works best on Samsung devices running Android 8 through 12. Within that range success is not guaranteed on every device. It depends heavily on your specific Samsung model and the firmware build date on your device. Two phones running the same Android version can respond completely differently to the bypass if one has a recent security patch and the other doesn’t.
Here’s the honest breakdown:
| Android Version | Success Rate | Notes |
|---|---|---|
| Android 5 and 6 | Medium | Works on some older Samsung models |
| Android 7 | Medium | Hit or miss depending on model |
| Android 8 and 9 | High | Best overall range for this tool |
| Android 10 and 11 | Medium to High | Firmware dependent |
| Android 12 | Medium | Newer patches reduce success |
| Android 13 and above | Low | Not the right tool for these versions |
If your Samsung is on Android 13 or above King Tool is unlikely to help. ZeroKnox Removal Tool 2.4 and HalabTech FRP Tool cover newer Android versions more reliably. Both are covered in our Samsung FRP Tools guide.
The other honest thing to say is that King Tool’s success rate varies more than most guides admit. It performs best on older Samsung devices with firmware from before 2023. On devices with 2024 and 2025 patches even within the supported Android range the success rate drops noticeably. If King Tool fails after a proper attempt try SamFw or ZeroKnox before giving up on free tools entirely.
Free vs Paid Features
King Tool is free to download and the core FRP removal function is completely free. You don’t need credits, an account or server authentication for standard Samsung FRP bypass using the Alliance Shield method.
Some newer versions of King Tool have introduced advanced features that require a paid upgrade. These include certain extended device support functions for newer Samsung models and additional bypass methods beyond the Alliance Shield approach. For the standard use case of bypassing FRP on a Samsung device running Android 8 through 12 the free version has everything you need.
If you encounter a prompt asking for payment or activation while attempting a standard FRP bypass on a supported Samsung model that’s unexpected behavior. The core bypass function is and has always been free. Close the tool, redownload from the link at the bottom of this page and try again with the clean free build.
Key Features
Here’s what King Tool can do:
Alliance Shield FRP Bypass The primary function and the heart of how this tool works. Alliance Shield is a Samsung Knox based application that gains access to device management functions through Knox’s enterprise layer. King Tool uses it as the delivery mechanism for the FRP removal command, bypassing the need for ADB debugging to be manually enabled first on the locked device.
Multiple Bypass Methods King Tool isn’t limited to just one approach. Depending on your Samsung model and Android version the tool offers different bypass paths. The Alliance Shield method is the primary one but the tool includes alternative approaches for models where Alliance Shield doesn’t get traction.
Tablet Support King Tool explicitly supports Samsung tablets in addition to Samsung smartphones. This is worth noting since many Samsung FRP tools focus only on phones and don’t cover the Tab series properly.
Windows Compatibility The tool runs on Windows XP, 7, 8, 10 and 11 in both 32 and 64 bit. This broad compatibility means you don’t need a modern PC to use it. An older Windows 7 machine in a repair shop will handle it without issues.
Completely Free for Core Functions No credits, no dongle, no server dependency, no annual renewal. The Alliance Shield bypass is available without spending anything.
Partial Xiaomi and Motorola Support Based on community feedback King Tool has produced successful results on some Xiaomi and Motorola devices in addition to Samsung. This isn’t officially documented and success on non-Samsung devices is inconsistent, but it’s worth a try if you have a Xiaomi or Motorola device and other tools haven’t worked.
Supported Devices
Samsung is where King Tool delivers the most consistent results. Here’s the breakdown:
| Brand | Supported | Android Range | Notes |
|---|---|---|---|
| Samsung Galaxy A Series | Yes | Android 8 to 12 | Best support overall |
| Samsung Galaxy M Series | Yes | Android 8 to 12 | Solid support |
| Samsung Galaxy J Series | Yes | Android 5 to 10 | Older models work well |
| Samsung Galaxy S Series | Some models | Android 8 to 12 | Mid-range better than flagship |
| Samsung Galaxy Tab | Yes | Android 8 to 12 | Explicit tablet support |
| Samsung Galaxy Note | Some models | Android 8 to 11 | Varies by model |
| Xiaomi | Partial | Android 8 to 11 | Community reported, not guaranteed |
| Motorola | Partial | Android 8 to 10 | Community reported, not guaranteed |
For Samsung the A and M series have the most consistent results across the supported Android range. The S series flagship models with newer security patches are more unpredictable even within the supported Android versions. J series devices on older firmware are generally straightforward.
For Xiaomi and Motorola treat it as a bonus rather than a primary plan. If you have one of these and other tools have failed King Tool is worth a single attempt. If it doesn’t work on the first try move to a tool with explicit non-Samsung support like AMT Tool.
What You Need Before Starting
Get everything ready before downloading anything:
A Windows PC running Windows XP, 7, 8, 10 or 11. Both 32 and 64 bit are supported. Windows 10 or 11 gives the best experience but the tool is genuinely compatible with older systems.
Samsung USB drivers installed. Without these the tool cannot detect your device. Download them from our drivers page and install before connecting anything. Restart your PC after driver installation.
A USB data cable that supports data transfer. Not a charging only cable. If the tool isn’t detecting your device the cable is the first thing to check, not the drivers or the tool itself.
Driver signature enforcement awareness. King Tool requires you to disable Windows driver signature enforcement during the bypass process. This is a built in Windows security feature that blocks unsigned drivers and certain system level operations. King Tool walks you through this with its Disable Signature Drivers button but you need to know it’s coming and be comfortable doing it. We cover exactly what happens in the step by step section below.
Wi-Fi connected on the locked Samsung device. The Alliance Shield component needs internet access during the bypass process. Connect the locked device to Wi-Fi on the setup screen before starting the PC side of the process.
Your device charged to at least 30%. The bypass involves several steps and a device restart. A dead battery mid-process creates more problems than you started with.
Antivirus temporarily disabled. King Tool communicates with device firmware at a system level and most antivirus programs flag it. Disable your antivirus before extracting and running the tool. Re-enable it after the bypass is complete.
WinRAR or 7-Zip on your PC. The tool comes as a compressed archive. You need one of these to extract it before running.

How to Install and Set Up
King Tool is portable. No traditional installer, no registry changes. You extract and run directly.
Step 1: Extract the archive Locate the downloaded ZIP or RAR file in your downloads folder. Right click and select Extract Here using WinRAR or 7-Zip. Extract to a folder on your desktop or C drive. Never run the tool from inside the archive.
Step 2: Disable antivirus Before opening the extracted folder disable your antivirus completely. Some programs delete the tool files during extraction itself, not just when you try to run them. Adding the folder to your exclusion list before extracting is the safest approach.
Step 3: Install Samsung USB drivers If you haven’t installed Samsung USB drivers yet go to our drivers page and do it now. Restart your PC after installation.
Step 4: Open the tool as administrator Open the extracted folder and find the King Tool executable. Right click it and select Run as Administrator. Running without admin rights causes detection failures and the Disable Signature Drivers function won’t work correctly without elevation.
Step 5: Connect your Samsung to Wi-Fi first Before connecting the Samsung to your PC make sure it’s connected to a Wi-Fi network on the FRP setup screen. Alliance Shield needs internet access to function. Do this step before plugging in the USB cable.
Step 6: Connect the device Plug the Samsung into your PC via USB data cable. King Tool should detect it within a few seconds and display the device information.
That is the full setup. You are ready to start the bypass.
Step by Step FRP Bypass Guide
This covers the Alliance Shield method which is the primary and most reliable bypass approach in King Tool.
Step 1: Open King Tool as administrator and connect your device Make sure the Samsung is on the FRP setup screen, connected to Wi-Fi and plugged into your PC via USB. King Tool should show the device as detected.
Step 2: Click Disable Signature Drivers In the King Tool interface click the Disable Signature Drivers button. This is the step most guides don’t explain properly. What this does is temporarily modify your Windows boot configuration to allow unsigned drivers and system level operations that Windows would normally block. The tool does this automatically when you click the button.
After clicking you will see a prompt telling you that your PC needs to restart. Save any open work on your PC and click Confirm or OK to proceed.
Step 3: PC restarts into special boot mode Your PC will restart and instead of booting normally it will show a blue screen with startup options. This is completely normal and expected. You will see a numbered list of startup options. Look for the option that says Disable Driver Signature Enforcement and press the corresponding function key to select it. This is usually F7 but the screen will tell you exactly which key to press.
Your PC will then boot into Windows normally but with driver signature enforcement temporarily disabled for this session only. After you restart again normally it re-enables automatically.
Step 4: Reopen King Tool as administrator Once Windows finishes booting open King Tool again by right clicking and selecting Run as Administrator. Reconnect your Samsung if it disconnected during the restart. The device should appear as detected again.
Step 5: Select Alliance Shield In King Tool find the Alliance Shield option and click it. The tool will begin pushing the Alliance Shield application to your Samsung device through the USB connection. Watch the progress in the tool’s log area.
Step 6: Follow on-screen instructions on the Samsung On the Samsung device screen you will see prompts appearing related to Alliance Shield installation. Follow them as they appear. Allow any permission requests that come up. Alliance Shield is installing itself as a device administrator through Knox’s enterprise management layer.
Step 7: Click Bypass FRP Once Alliance Shield is installed on the Samsung return to King Tool on your PC and click Bypass FRP. The tool sends the FRP removal command through Alliance Shield’s enterprise management access. This removes the Google account verification requirement from the device.
Step 8: Wait for completion The bypass process takes 2 to 5 minutes. Don’t disconnect the cable, don’t close King Tool and don’t touch the Samsung screen during this process. Let it run completely.
Step 9: Cold restart the Samsung When King Tool shows a success message disconnect the USB cable from the Samsung. Hold the power button until the device fully shuts down. Wait 10 seconds. Power it back on manually. Do not let King Tool or the device trigger an automatic restart. A proper cold boot is important for the FRP removal to take full effect.
Step 10: Complete setup Go through the normal Samsung setup process. The Google account verification screen should be gone. Add any Google account you have access to and complete setup normally.
Driver Signature Enforcement Fix
Since King Tool requires disabling driver signature enforcement it’s worth understanding this fully so you know what to do if something goes wrong during the process.
Windows 8, 10 and 11 block unsigned drivers and certain system level operations by default as a security measure. King Tool’s Disable Signature Drivers button handles this automatically for one session by configuring your PC to boot with enforcement disabled. The key things to understand are:
It only applies to one boot session. After you restart your PC normally following the bypass, driver signature enforcement re-enables automatically. You don’t need to do anything to turn it back on.
If King Tool’s button doesn’t work or your PC doesn’t show the startup options screen after restarting you can do it manually. Hold Shift and click Restart from the Start menu. Select Troubleshoot, then Advanced Options, then Startup Settings, then Restart. After the PC restarts press F7 to select Disable Driver Signature Enforcement.
If you want to verify the current state of signature enforcement open Command Prompt as administrator and run bcdedit /enum. Look for the testsigning and nointegritychecks values. Both should say No in normal operation.
Errors and Fixes
Tool doesn’t detect the Samsung device Install Samsung USB drivers from our drivers page and restart your PC before connecting the device again. Check you’re using a data cable not a charging cable. Make sure the tool is running as administrator. Try a different USB port, preferably USB 2.0 rather than 3.0.
Disable Signature Drivers button does nothing The tool must be running as administrator for this function to work. Close King Tool completely, right click the executable and select Run as Administrator, then try the button again. If it still does nothing use the manual method through Advanced Startup described in the Driver Signature section above.
PC restarts but doesn’t show startup options screen Some Windows configurations hide the startup options menu. Use the manual method instead. Hold Shift, click Restart from the Start menu, go through Troubleshoot, Advanced Options, Startup Settings, Restart, then press F7 when the numbered list appears.
Alliance Shield installation fails on the Samsung Check that the Samsung is connected to Wi-Fi on the setup screen. Alliance Shield needs internet access to install. Also confirm the USB cable is still connected and the tool is still showing the device as detected. If Alliance Shield installation keeps failing try a different USB cable and reconnect.
Bypass FRP button shows error after Alliance Shield installs Close King Tool, restart it as administrator and try the Bypass FRP step again without going through the Alliance Shield installation again. On some devices the two steps need separate tool sessions to work correctly.
FRP removal completes but verification screen still appears Do a complete cold restart. Hold the power button until the Samsung fully shuts down. Count 10 seconds. Power it on manually. If the screen still appears after a clean cold boot run the bypass again from Step 5. Some Samsung models need two passes through the Alliance Shield method before the FRP flag is fully cleared.
King Tool works but asks for payment for the bypass function You may have downloaded a modified or newer paid version. Download the clean free build from the link at the bottom of this page. The core Alliance Shield FRP bypass is free and should not require payment.
Samsung on Android 13 or above not responding to the bypass King Tool is not the right tool for Android 13 and above. Move to ZeroKnox Removal Tool 2.4 or HalabTech FRP Tool for newer Android versions. Both are free and designed specifically for Android 13 through 16. Read our Samsung FRP Tools guide for the complete comparison.
FAQ
Is King Tool completely free for Samsung FRP removal?
The core Alliance Shield FRP bypass is completely free. No credits, no account, no server dependency. Some advanced features in newer versions may prompt for payment but standard FRP removal on supported Samsung models should not cost anything. If you’re being asked to pay for a basic bypass download the clean free build from this page.
Which Samsung models work best with King Tool?
Samsung Galaxy A series and M series devices on Android 8 through 12 have the highest success rates. J series devices on older firmware also work well. S series flagship models with recent security patches are less reliable even within the supported Android range.
Does King Tool work on Android 13 and 14?
No reliably. King Tool’s bypass methods were built around vulnerabilities that existed up to Android 12. On Android 13 and above the success rate is very low. Use ZeroKnox Removal Tool 2.4 or HalabTech FRP Tool for Android 13 through 16 Samsung devices.
What is Alliance Shield and why does King Tool use it?
Alliance Shield is a Samsung Knox based enterprise management application. It gains access to device administration functions through Knox’s enterprise security layer. King Tool uses it as the bypass delivery mechanism because Knox enterprise access allows system level changes that bypass the standard Google account verification requirement. It’s a clever approach that doesn’t require ADB debugging to be manually enabled first.
Will disabling driver signature enforcement cause any permanent changes to my PC?
No. Driver signature enforcement disabling through the Startup Settings method only applies to one boot session. After your PC restarts normally it re-enables automatically. Your system returns to its normal security state after the bypass is complete and you restart.
Does King Tool work on Samsung tablets?
Yes. Samsung tablet support is explicitly included in King Tool. The Galaxy Tab series is supported alongside Samsung smartphones within the same Android version range.
Can I use King Tool on Xiaomi or Motorola devices?
Some community members have reported success on certain Xiaomi and Motorola models but this is not officially supported or documented. Success on non-Samsung devices is inconsistent. If you have a Xiaomi or Motorola device King Tool is worth one attempt but AMT Tool or Android Multi Tools are more reliable options for those brands.
