Bypass FRP on ZTE Blade A55 (Android 14) – Free Tool

How to Bypass FRP on ZTE Blade A55 (Android 14) – Free Tool

Getting stuck on the Google Account Verification screen (FRP) after a factory reset can be frustrating, especially on the latest ZTE Blade A55 (Z2450) running Android 14. Since this device uses the Unisoc SC9863A1 chipset, you need a specific tool to handle the security patch.

In this guide, we will use the BFT (Best Flash Tool) to unlock your device for free.

Phase 1: Preparation & Requirements

Before starting, ensure you have a stable Windows PC and a high-quality USB cable. Follow these steps precisely to avoid connection errors:

1. Install SPD Drivers: Download and install the Spreadtrum (SPD) drivers to ensure your PC recognizes the phone in "BROM" or "Download" mode.

   • Download Link: SPD Drivers

2. Disable Antivirus: Most flash tools are flagged as "False Positives" by Windows Defender. Disable your real-time protection temporarily to allow the tool to run.

3. Download BFT (Best Flash Tool):

   • Download Link: BFT Tool

   • RAR Password: RSL Mobile Solution

Phase 2: Configuring the Tool

Once installed, follow these UI instructions to set up the Unisoc SC9863A configuration:

• Login: Open the BFT shortcut from your desktop. You don't need a username; simply click Login.

• Chipset Selection: On the top-left corner, click the dropdown (defaulted to MediaTek) and select 0-UNISOC.

• Manual Mode: Check the Manual tick box located slightly to the right.

• Model/Auth Selection: In the center-top dropdown, change [AUTH] SC7731E to [AUTH] SC9863A.

Phase 3: The FRP Bypass Process

Now that the tool is ready, follow these steps to reset the lock:

1. Navigate to the bottom-left tabs and select the Service tab (between Flash and Diag).

2. Click on the FRP Reset button.

3. Power off your ZTE Blade A55 completely.

4. The Connection Trick: Hold both Volume Up + Volume Down buttons simultaneously. While holding them, plug in the USB cable.

5. The tool will detect the device and start the process.

Note: The process usually takes 30 to 40 seconds. Once the "Success" message appears, you can unplug your phone and reboot it.

Why this works?

The ZTE Blade A55 uses the SC9863A1 architecture. By using the BFT tool in "Auth" mode, we bypass the secure boot string of Android 14, allowing the system to wipe the persistent "Config" partition where the Google Lock data is stored.
