Downgrading the software on any device carries some risks, as it can potentially cause instability or compatibility issues. However, if you still want to proceed with downgrading your Vivo Y15, here is a general guide on how to do it safely:

1. Backup your data: Before making any software changes, it is crucial to back up your important data such as contacts, photos, videos, and documents. This will ensure that even if something goes wrong during the downgrade process, you won't lose your valuable data.

2. Find the appropriate firmware: Look for the firmware version you want to downgrade to. You can typically find the firmware on the official Vivo website or other reliable sources. Make sure to download the correct firmware for your specific Vivo Y15 model.

3. Enable USB debugging: To downgrade your Vivo Y15, you will need to enable USB debugging. Go to Settings > About Phone > tap on Build Number seven times to enable Developer Options. Then go to Developer Options > enable USB Debugging.

4. Install necessary tools: Download and install the Vivo USB drivers on your computer. This will enable your computer to communicate with your Vivo Y15 during the downgrade process.

5. Prepare the firmware: Extract the downloaded firmware file to a convenient location on your computer. You should find a file with a .zip or .rar extension.

6. Boot your Vivo Y15 into Fastboot mode: Power off your device and then press and hold the Volume Up and Power buttons simultaneously until the Fastboot menu appears.

7. Connect your device to the computer: Connect your Vivo Y15 to your computer using a USB cable.

8. Launch the firmware flashing software: Open the firmware flashing tool on your computer. Some popular flashing tools for Vivo devices include SP Flash Tool, QFIL, or MSM Download Tool. Consult the specific instructions provided by the tool you choose for further guidance.

9. Begin the downgrade process: Once you have opened the flashing tool, locate and select the firmware file you extracted earlier. Follow the on-screen instructions provided by the flashing tool to start the downgrade process.

10. Wait for the process to complete: The flashing tool will start installing the older firmware on your Vivo Y15. Do not disconnect your device or interrupt the process until it is complete. This may take a few minutes.

11. Reboot your device: After the downgrade process is successfully completed, your Vivo Y15 will automatically reboot. It may take a bit longer than usual for the device to start up as it adjusts to the downgraded firmware.

Remember that downgrading firmware can have unforeseen consequences, so proceed at your own risk. If you encounter any issues or difficulties during the process, it is best to seek assistance from official Vivo support or a reputable technician.
