In this article, we'll explore the process of writing and restoring factory files for a Vivo 1601 device. This guide is designed to help users who have pattern-locked their Vivo 1601 phone and are unable to access its contents.

The Problem

Many Vivo 1601 users have reported an issue where they read the factory file, wrote the same file, and now their phone is stuck on the logo screen. This problem occurs when users attempt to restore the phone's factory settings without properly configuring the process.

Understanding Scatter Files

To resolve this issue, we'll need to understand how scatter files work. A scatter file is a type of firmware file that contains information about the device's hardware and software configuration. It serves as a blueprint for writing and restoring factory files on Vivo devices.

Writing Factory Files

The first step in recovering your Vivo 1601 is to write the factory files using a tool like UniTool_EXT. This process involves connecting your phone to your computer via USB, then running the UniTool_EXT software. The software will prompt you to select the scatter file for your device (in this case, the Vivo 1601). Once the scatter file is selected, the software will guide you through the process of writing the factory files.

Restoring Factory Files

After writing the factory files, the next step is to restore them on your phone. This process involves rebooting your phone in recovery mode (usually by pressing and holding the power button and volume down button simultaneously) and selecting the "Restore" option from the recovery menu. The phone will then apply the newly written factory files.

Tips and Tricks

To avoid running into issues like the one described above, it's essential to follow these tips:

1. Always backup your data before attempting to restore the factory settings.
2. Make sure you have the correct scatter file for your device (in this case, the Vivo 1601).
3. Follow the software's instructions carefully when writing and restoring factory files.
4. If you encounter any issues during the process, don't hesitate to seek help from online forums or professional repair services.

****, recovering a Vivo 1601 phone that is stuck on the logo screen requires a thorough understanding of scatter files and the process of writing and restoring factory files. By following the steps outlined above and using the right tools, you should be able to successfully recover your phone's contents. Remember to always backup your data before attempting any restoration procedures.
