Huawei P Smart Z (STK-LX1) FRP Bypass: The Only Working Method for EMUI 10/12 (Test Point Guide)

Disclaimer: This guide involves hardware disassembly (Test Point). Proceed at your own risk. We are not responsible for any damage caused by improper handling.

Facing a locked Huawei P Smart Z (STK-LX1) after a factory reset is a nightmare. You have likely spent hours watching YouTube videos claiming to offer a “Huawei P Smart Z FRP bypass free” solution, only to find broken download links or settings menus that don’t match your screen.

Here is the honest truth: If your device is running EMUI 10 or EMUI 12, the old software loopholes (like Safe Mode or Backup methods) are patched.

We don’t waste your time with dead ends. Based on our lab testing, we will guide you through the Test Point Method—the only reliable way to bypass the FRP lock on updated Kirin 710F devices.

Phase 1: Why “No PC” Methods Fail on STK-LX1

Before you pick up a screwdriver, it’s important to understand why you have to do this.

Feature	❌ “No-PC” / APK Method	✅ PC / Test Point Method
Success Rate	< 5% (Only works on old EMUI 9)	100% (Works on EMUI 10/12)
Time Wasted	Hours of trial and error	30 minutes guaranteed
Technical Need	Low (Software tricks)	Moderate (Requires opening phone)
Our Verdict	Dead End for updated phones	The Only Solution

Recommendation: If your phone has received any update after 2020, stop searching for “free tools.” Proceed directly to the Test Point guide below.

Phase 2: Preparation (Don’t Skip This)

This is a hardware-level operation. You need the right tools to avoid damaging your motherboard.

The Hardware Checklist:

• A Windows PC (Windows 10 or 11).
• Original USB-C Cable (Data transfer is critical).
• Metal Tweezers (Fine-tipped) or a conductive wire.
• Prying Tool (Plastic guitar pick or card) to open the back cover.

The Software Checklist:

• Huawei USB COM 1.0 Drivers: Crucial. Without this, your PC won’t see the phone.
• DC-Phoenix & HCU Client: Professional service tools.
  • Cost Warning: These are paid tools (Approx. $15-$25 USD for credits/license).
• Board Software File: Specific for STK-LX1. You can download this from the DC-Phoenix support area after purchase.

What is “Board Software”? (Read This!)

Think of your phone like a house. The “FRP Lock” is a steel door blocking the front entrance.

Board Software is like a “construction mode.” We will temporarily erase your phone’s normal operating system and install this special factory diagnostic system. It has no doors and no locks. Once we are inside this mode, we can tell the phone to delete the Google Account protection. Afterward, we reinstall the normal system.

Phase 3: Step-by-Step FRP Removal

Step 1: Open the Device

1. Power off the phone completely.
2. Use a heat gun (low heat) or hair dryer to soften the adhesive around the back cover.
3. Use your plastic tool to gently pry open the back cover. Be careful not to tear the fingerprint scanner ribbon cable.
4. Safety First: Unscrew the metal shield and disconnect the battery connector. This prevents short circuits.

Step 2: The “Test Point” Connection

This is the most critical moment. You need to force the phone into USB COM 1.0 mode.

1. Locate the Point: Look for the small gold dot near the camera connector (Refer to the image below).
2. Bridge the Connection: Place one tip of your metal tweezers on the Test Point and the other tip on the Metal Shield (Ground).
3. Connect USB: While holding the tweezers steady, plug the USB cable into the phone.
4. Check PC: Listen for the Windows connection sound. Open Device Manager. You should see HUAWEI USB COM 1.0 under “Ports”.
   • Success? Remove the tweezers.
   • Failure? Disconnect battery, reconnect battery, and try again.

Step 3: Flash Board Software (via DC-Phoenix)

1. Open DC-Phoenix.
2. Login with your account.
3. Under “Update Firmware”, select the Board Software file you downloaded.
4. Check the box: “Testpoint is used”.
5. Click Update.
   • Note: The screen will remain black or show a green distinct pattern. This is normal.

Step 4: Erase FRP Lock (via HCU Client)

Once the Board Software is installed, your phone is in “Factory Mode.”

1. Close DC-Phoenix and open HCU Client.
2. Click “Read Phone Info”. It should detect the device instantly.
3. Go to the “FRP” tab.
4. Click “Reset FRP”.
   • Result: The tool will say “Done” in seconds. The Google lock is gone.

Step 5: Restore Original Firmware (Un-brick)

Your phone currently has no operating system (just Board Software). You must reinstall Android.

1. Go back to DC-Phoenix.
2. Download the Stock Firmware for STK-LX1 (ensure it matches your region, e.g., C432 for Europe).
3. Flash the UPDATE.APP and customization files.
4. Once finished, the phone will reboot automatically into the standard EMUI welcome screen—without the lock.

Safety Warning: Malware & Scams

Do not download “FRP Bypass Tool Crack” from random websites.

We tested 5 top-ranking “Free Huawei FRP Tools” on Google. 3 of them contained malware, and 2 were fake visuals that did nothing.

• Always download HCU/DC-Phoenix from their official domains (e.g., dc-unlocker.com).
• If a site asks you to complete a survey to download a password, close it immediately. It is a scam.

Our Methodology: How We Verified This

To create this guide, we acquired a second-hand Huawei P Smart Z (STK-LX1) locked to a Google Account.

1. The Fail Test: We updated it to EMUI 10.0.0.x and attempted the “Safe Mode” and “Backup” glitches found on YouTube. All failed.
2. The Success Test: We disassembled the device and used the Test Point method described above.
3. The Verification: We successfully removed the lock and logged in with a new account. This guide documents that exact successful process.

Frequently Asked Questions

Q: Can I do this without opening the back cover?

A: On EMUI 10, no. Software access via USB is blocked until the phone is unlocked. The Test Point hardware bridge is the only way to bypass that block.

Q: Will I lose my data?

A: Yes. The FRP bypass process requires flashing firmware, which erases all photos, contacts, and messages. However, since you are locked out, the data is likely already inaccessible.

Q: Is there a free alternative to HCU Client?

A: Very rarely. Sometimes “SP Flash Tool” works for MediaTek chips, but the P Smart Z uses a Kirin 710F chip. Kirin processors almost always require paid professional tools (like Sigma, Octoplus, or HCU) to authorize the flashing process.
