First, OPPO smartphones are really great. They are a durable and high-performing brand of modern smartphones.

This becomes difficult and that is where you get stuck. But for today, we are all going to learn How to unlock the OPPO A5S smartphone.

Step 2

After launching the MRT dongle through whichever means best suited for you, after MRT is launched, on the dashboard, click on the OPPO tab. Now on the left-hand side, under “Mobile Options” select our OPPO A5S that we want to format and unlock security code. Select “A5S.”

Now, under that under operational options, click on the “Format (Unlock)” button. Now, having done that, hoping that you have already installed the Oppo MTK drivers, click on the Start button just below MRT.


Now, at this point, the remaining work is much simple. This is the point where we are going to now format all data on our OPPO A5S and unlock the security code. Now, make sure that your phone is charged at least 50% of the charge. Hold the power key to power off your phone. Now connect the USB data cable to the computer USB port.

On the phone, hold both volume up and volume down keys at the same time. Connect your OPPO A5S to the computer. As soon as you hear the connection sound and you see that MRT has recognized your device, release both keys and put the phone on a flat surface where you won’t interfere with the flashing process. Now, the phone will boot into Meta mode. You will see the screen turn on and change to green color. Don’t panic. Everything is ok. As soon as the phone goes into Meta mode, MRT will begin formatting it. Wait until you see “All is done” disconnect your phone from the computer and hold the power key to power it up.


Step 4

After flashing is done disconnect your OPPO A5S from the computer, power it up by holding the power button. After it is powered, kindly easily set up your phone by completing the factory setup instructions and set up your phone again. You should be able to now freely use your OPPO A5S phone without the security code. In the next article, I will show you how to bypass FRP on OPPO A5S smartphones.
