For Qualcomm processor-based Android phones, the materials and tools needed to Unlock pattern locks or PINs are generally consistent across different models. You will need the appropriate eMMC Firehose program file for your target device, RBSoft Mobile Tool software, and a USB data cable.

In this guide, we will specifically cover how to Unlock the pattern lock, PIN, and Google account (google account verification) on the Oppo A37. What makes this device particularly convenient is that you do NOT need to disassemble the back cover or use the test point method to enter EDL mode; there is a simpler button combination method instead!

Important Prerequisites & Safety Notes

Before proceeding, please read these critical points carefully:

• Data Loss Warning: This process will erase all user data on your Oppo A37, including contacts, apps, and settings. Your device will be restored to the factory default state. Note that files stored on the internal SD card may remain safe, but contacts will definitely be deleted.
• Legal & Ethical Use: This guide is intended for legitimate owners who have forgotten their lock screen credentials or purchased a second-hand device that is locked. Unauthorized access to devices that do not belong to you is illegal and unethical.
• Technical Risks: Improper execution may cause software issues. Proceed at your own risk.
• google account verification Awareness: After resetting the device, Google’s Factory Reset Protection (google account verification) will activate automatically. This guide covers how to Unlock both the lock screen and google account verification for legitimate cases.

What You Need to Prepare

First, gather the following files and tools:

1. Computer or Laptop: Running Windows operating system with a stable internet connection (mandatory for RBSoft to function).
2. USB Data Cable: A good-quality cable to connect the phone to your computer.
3. RBSoft Mobile Tool: The main software used for this Unlock process.
4. eMMC Firehose Program File for Oppo A37: This file can be extracted from the official Oppo A37 flash ROM (firmware) file.

How to Unlock Pattern Lock, PIN & google account verification Google Account on Oppo A37 (No Test Point Needed)

Step 1: Enter EDL Mode on Oppo A37 (No Disassembly Needed!)

The great thing about the Oppo A37 is that you can enter EDL (Emergency Download) mode without opening the phone casing or using test points:

1. Power off your Oppo A37 completely.
2. Press and hold both the Volume UP and Volume DOWN buttons simultaneously.
3. While holding both volume buttons, connect the phone to your computer using the USB data cable.
4. Verify EDL Connection:

• Open Device Manager on your computer (right-click "My Computer" → "Manage" → "Device Manager").
• Expand the "Ports (COM & LPT)" section.
• If successful, you will see "Qualcomm HS-USB QDLoader 9008" listed there. This confirms your phone is properly connected in EDL mode.

Step 2: Prepare the Firehose File

1. Locate the Prog Emmc Firehose file for Oppo A37 that you downloaded earlier.
2. Copy and paste this file to your Desktop for easy access when loading it in the tool later.

Step 3: Unlock Pattern/PIN Lock Using RBSoft Mobile Tool

Preparation:

• Ensure your computer has a stable internet connection (this is mandatory).
• Temporarily disable your antivirus software to prevent it from blocking RBSoft's operations.

Unlock Steps:

1. Open RBSoft Mobile Tool and log in using the Username and Password provided in the "How to Use" notepad file included with the tool package.
2.  After successful login, check the "Manual Loader" option.
3. Click the "Browse" button and load the eMMC Firehose file for Oppo A37 that you copied to your Desktop.
4. To Unlock Pattern Lock / PIN: Click the "Format Userdata" button. This will erase all user settings and remove the pattern/PIN lock from the device.
5. Wait for the process to complete: Monitor the "Logs Window" in RBSoft. A successful process will end with the status "OK" highlighted in green.
6. Once successful, the phone will automatically exit EDL mode and enter charging mode.
7. Power on your Oppo A37 to verify that the pattern/PIN lock has been successfully removed. You will be greeted with the initial device setup screen.

Step 4: Unlock google account verification (Factory Reset Protection) Google Account

After successfully Unlocking the pattern lock, you will likely encounter a new issue: the phone is now locked by Google's Factory Reset Protection (google account verification). To Unlock this:

1. Enter EDL mode again using the same method as Step 1 (press Volume UP + DOWN simultaneously while connecting USB).
2. Open RBSoft Mobile Tool again (ensure the internet is connected and antivirus is disabled).
3.  Load the same eMMC Firehose file for Oppo A37.
4.  Click the "Reset google account verification" button to Unlock the Google account verification.
5. Wait for the process to complete. You will see the "OK" status in green in the Logs Window.
6. The phone will automatically restart; do not interrupt this process or turn off the phone. The system is restarting and preparing itself after the forced reset.

Step 5: Final Device Setup

1. Once the phone restarts, you will see the initial preparation screen. Follow the on-screen setup steps.
2. When prompted, connect the phone to a Wi-Fi network.
3. During the Google account verification step, you will now see a "Skip" button appear on the screen. Click this button to Unlock the Google account login.
4. Continue with the remaining setup steps according to your preferences.

Conclusion

Congratulations! You have successfully Unlocked both the pattern/PIN lock and Google account (google account verification) on your Oppo A37 all without needing to reflash the entire firmware.
