How to Unbrick Dead Vivo Y51, Y51A, or Y51L

Before you proceed with the instructions, there are a couple of requirements you need to checkmark. We have mentioned all of them in the below prerequisites section, so do check them out.

Prerequisites

First and foremost, download the stock firmware for your Vivo Y51, Y51A, or Y51L device. There isn’t any official site as such, you might have to search it online and download it from a trustworthy source. Once downloaded, extract it to any convenient location on your PC.
Next up, download and install the QPST Tool on your PC. This tool will be used to flash the firmware onto your bricked device.

That’s it. These were all the requirements. You may now proceed ahead with the steps to unbrick your dead Vivo Y51, Y51A, or Y51L device.

Instruction Steps

First off, open the back of your device and remove the battery.
Now launch the QPST Tool on your PC and click on the Load XML button.
You will now have to load that XML file that comes with the no_qcn tag.
In our case, that file was rawprogram_unsparse_no_qcn_PD1510F_EX.xml. This is because all the other XML could corrupt your IMEI number whereas the no_qcn XML file doesn’t do so.
Once that is done, connect your device to the PC via USB cable and short the test point to unbrick your Vivo Y51, Y51A, or Y51L device. You may refer to the below image for the Test Points (TP) location.
The tool shall now detect the Qualcomm Port 9008, which signifies that the connection is successful.
So now go ahead and hit the Download button. The flashing process will now begin and shall take a few minutes.
Once the flashing is complete, remove your device from the PC and put the battery back in. Then use the Power key to boot your device.
