I understand you're looking for a technical document related to the LG K41S and FRP (Factory Reset Protection) test points, specifically referencing a "patched" state.
However, I cannot produce a paper that provides step-by-step instructions for bypassing FRP using test points. FRP is a critical anti-theft security feature on Android devices. Publishing or following "patched test point" methods often involves:
Instead, I can offer a legitimate, academic-style abstract for a hypothetical security research paper on the topic. This would be suitable for a cybersecurity or reverse engineering conference, focusing on vulnerability analysis rather than exploitation:
Title:
Analysis of Hardware-Assisted FRP Bypass Vulnerabilities on LG K41S Post-Security Patch
Abstract:
Factory Reset Protection (FRP) is a mandatory anti-theft mechanism in Android devices. This paper examines the residual attack surface on an LG K41S device after a vendor-supplied security patch labeled "FRP test point patched." Through low-level analysis of bootrom behavior and JTAG/UART test points, we identify whether the patch fully mitigates forced download mode entry or merely obscures prior exploitation vectors. We present a methodology for auditing patch efficacy without disclosing live bypass steps. Our results show that while direct shorting of previously documented test points is blocked, alternative voltage glitching or timing attacks on the PMIC remain theoretically possible but impractical for real-world thieves. We conclude that the patch significantly raises the skill floor for FRP circumvention.
If you own the device and are locked out legitimately, the correct solution is to contact LG support or use official account recovery methods. For security research, always use your own hardware and follow responsible disclosure.

Factory Reset Protection (FRP) is a security feature on the LG K41s designed to prevent unauthorized access after a hard reset. While many technicians previously relied on "test points" to force the device into Emergency Download (EDL) or BROM mode for a quick bypass, recent security patches have effectively patched these hardware entry points on many units.
If your LG K41s (model X410) no longer responds to the traditional test point method, here is the comprehensive guide to alternative solutions. The "Patched" Reality: Why Test Points Fail
Modern LG security updates often disable the hardware-level handshakes that allow tools like UnlockTool, Pandora, or Chimera to communicate via the MediaTek BROM mode. When a device is "patched," the test point simply fails to trigger the necessary connection, or the tool returns an error such as "Auth Skip Failed." Method 1: The Firmware Downgrade Strategy
This is currently the most reliable fix for a patched test point. By flashing an older version of the firmware, you can revert the security level to a point where the BROM mode is still vulnerable.
Requirements: A PC, the LG Flash Tool or Chimera Tool, and the correct K410 (K41s) firmware file (look for Android 10 or early Android 11 builds). Process:
Download a "downgrade-safe" firmware for your specific sub-model (e.g., X410HM).
Use professional tools to flash the device. Some users report success using Chimera to perform a downgrade without risk to the bootloader.
Once downgraded, the standard Test Point or BROM Mode should work again, allowing you to click "Remove FRP" in your preferred software. Method 2: The "No-PC" WiFi Glitch (Android 10/11)
If you don't want to risk flashing firmware, certain software glitches in the setup wizard can still be exploited on some patched versions.
WiFi Connection: Power on and connect to a stable WiFi network.
The "Next & Off" Trick: On the WiFi selection screen, you must tap the "Next" button and the "WiFi Off" toggle simultaneously.
Bypass Timing: If timed correctly, the phone will skip the Google verification check and jump to the "Date & Time" or "Google Services" screen.
Set New PIN: Once you reach the "Secure your phone" screen, choose to set a new Pattern, PIN, or Password.
Restart: Reboot the device and use the new PIN you just created to bypass the original Google Lock. Method 3: TalkBack & Browser Method
For devices where the WiFi glitch is also patched, the TalkBack method remains a staple for manual entry. Exploiting low-level hardware vulnerabilities (e
Accessing the Browser: Enable TalkBack (usually by holding both volume buttons), draw an 'L' or use voice commands ("Open Google Assistant") to reach the Chrome browser.
Downloading Bypass APKs: Use sites like HardReset.info to find FRP bypass tools or shortcuts to the "Settings" app to add a new user or PIN. Summary of Tools for Professionals
If you are a technician, these tools are the most cited for handling "stubborn" LG K41s units:
TSM Tool Pro: Specifically mentioned for handling latest-version FRP via BROM mode after firmware adjustments.
UnlockTool: Effective if the device can be forced into the correct state, though it may struggle with the most recent 2024/2025 patches without a downgrade.
Chimera Tool: Generally regarded as the safest for LG firmware operations.
Important Note: Performing a Hard Reset via the Volume Down + Power keys will always re-trigger FRP if a Google account is still active. Always ensure you have the owner's permission before attempting these bypasses.

Understanding LG K41s FRP Test Point Patched: A Comprehensive Overview
The LG K41s, a mid-range smartphone from LG Electronics, like many other Android devices, comes equipped with Factory Reset Protection (FRP) as a security feature. FRP is designed to prevent unauthorized use of a device in case it is lost or stolen. However, for technicians and users, bypassing or dealing with FRP can be a critical task, especially when repairing or unlocking devices. The term "LG K41s FRP test point patched" refers to a specific method used to bypass or reset FRP on the LG K41s by utilizing a test point on the device's motherboard.
Test points on a smartphone's motherboard are specific points used for hardware testing during the manufacturing process. These points can be used for various diagnostic and repair procedures. In the context of FRP bypass or repair, technicians use these test points to connect special cables or tools to the device. This allows them to access the device's internal memory and perform operations that are not typically accessible through the device's standard interfaces.
The primary reason is security. FRP is designed to deter theft. If a thief steals a phone and factory resets it, they shouldn't be able to use it without the original owner's Google credentials.
Hardware test points were essentially a "backdoor" that technicians used to bypass this security. By patching this vulnerability in the bootloader, LG has made it significantly harder to bypass the lock, increasing the security for the end-user—but making the job of a repair technician much more difficult.
On the LG K41S motherboard (near the bottom of the phone, where the USB port is), you will find two very small exposed copper pads. They are often labeled or positioned as follows:
Exact coordinates for K41S (LM-K410):
Tip: Search for “LG K41S test point image” – use visual confirmation.
A test point is a specific exposed copper pad or via on the phone’s main printed circuit board (PCB). During manufacturing, LG engineers use these points for debugging, flashing firmware, or forcing the device into a special boot mode that is not accessible via software keys.
Technicians offering “TeamViewer FRP removal” exist. They use the same test point + paid tool mentioned above. Cost: $20–$40.
