Vivo Y91 Recovery Mode Tutorial Web Data Factory Reset

In this guide, we walk through the exact steps to access the special Vivo recovery screen and reset the device to its factory settings using the Web Data option. This method is commonly used by repair technicians to fix system lag, software glitches, boot-loop issues, or a device stuck on the logo screen — but it comes with one essential requirement explained below.

⚠️ Important Condition Before You Start

🔑 This method only works if you already know your own device password (screen lock PIN/pattern/password). The recovery menu on this Vivo model will ask you to confirm your password before allowing the Web Data reset to proceed. If you do not know your password, this guide will not help you unlock or bypass the device — it is strictly intended for users resetting their own phone with their own known credentials.

🚨 Safety Warning for Technicians and Users

Before performing a factory reset, please read the following carefully:

• 🚫 This is not a beginner-friendly operation. Factory resetting a device permanently erases all personal data, apps, photos, and settings. A mistake at the wrong step can result in a bricked device or a hard-locked device requiring specialized recovery tools.
• 🎓 Only technicians with proven mobile repair experience should perform system-level operations like this. Understanding recovery menus, bootloader behavior, and device-specific reset paths is essential before touching this menu.
• 💾 Always back up important data first — photos, contacts, and files — since a factory reset via recovery mode is irreversible once confirmed.
• 🔋 Ensure the battery is charged above 50% before starting. A power loss mid-reset can corrupt the system partition and cause a hard brick.
• 🖐️ Do not press random buttons in the recovery menu. Each option (Wipe Data, Web Data, Wipe Cache, etc.) performs a different action — selecting the wrong one can cause unintended data loss or system instability.
• 📵 If you are not confident performing this procedure, consult a certified repair technician rather than risking permanent damage to the device.

In short: this guide is for users who already know their password and for technicians with hands-on repair experience. If either condition isn't met, do not attempt this reset.

🧭 Why You Might Need a Factory Reset

A factory reset through the recovery menu is typically used to resolve:

1. Persistent system lag or a "frozen" / unresponsive interface
2. Software glitches or corrupted system files
3. The device being stuck on the boot logo screen
4. Forgotten screen lock pattern/PIN (⚠️ only applicable if you separately know your account/backup password required by the recovery menu)
5. Preparing the device for resale or handover
6. General performance restoration after long-term use

📋 Step-by-Step Factory Reset Guide

1️⃣ Power Off the Device

Completely shut down the phone before starting. Do not just lock the screen — a full power-off is required for recovery mode to boot correctly.

2️⃣ Enter Recovery Mode

• Press and hold the Volume Up button and the Power button at the same time.
• Keep holding both buttons until the special Vivo recovery screen appears. Note that this recovery interface looks different from the standard Android recovery menu found on most other Android devices.

3️⃣ Select "Web Data"

• Using the volume buttons to navigate and the power button to confirm, select the Web Data icon from the recovery menu.

4️⃣ Enter Your Password

• The system will prompt you to enter your device password. Enter your correct password to proceed.

5️⃣ Confirm the Second Prompt

• A second window will appear, again presenting the Web Data option. Select it once more to confirm the operation.

6️⃣ Wait for the Reset to Complete

• The device will now begin the formatting process. Do not interrupt the process, disconnect the battery, or press any buttons during this stage.
• Once finished, the device will reboot automatically to the initial setup screen, confirming the factory reset was successful.
