Here's a step-by-step guide using the ZTE Blade A35 Core update FRP bypass tool:

If the on-device method is unsuccessful, a PC-based tool is the next best course of action. These tools are generally more reliable for newer Android versions and security patches.

Boot the phone and connect to a stable network.

Download BFT Tool V1.7 from a trusted source and extract the contents to a folder on your PC.

If Method 1 fails due to security patches, try this alternative specifically for older ZTE firmware.

Download your chosen tool (e.g., SamFw Tool) and run it as an administrator. Turn off your ZTE Blade A35 Core completely.

This is a popular method for many ZTE phones that leverages a potential loophole in the default keyboard.
