How to flash?
Here’s a step-by-step guide for flashing the OPPO A3S (CPH1803) without authentication using the QPST (Qualcomm Product Support Tool) QFIL (Qualcomm Flash Image Loader) Tool:
Step 1: Download the Firmware
- First, download the latest firmware file for the OPPO A3S.
Step 2: Extract the Firmware
- Extract the firmware file to any location on your computer.
Step 3: Install the Necessary Drivers
- Install the Qualcomm drivers on your computer. If you have already installed the drivers, you can skip this step.
Step 4: Boot the OPPO A3S into EDL Mode
- Completely power off your OPPO A3S smartphone.
- Wait a few seconds, then press and hold both the Volume Up and Volume Down buttons.
- While holding the buttons, connect your phone to the computer using a USB cable.
- Check in the Device Manager to ensure that the Qualcomm 9008 port is created.
Step 5: Replace the loader.elf File
- Go to the extracted firmware folder and replace the
loader.elffile with the correct one. - If the firmware already contains a file with a different name, make sure to replace it with the
loader.elffile that you have.
Step 6: Extract the .OFP File
- The
.OFPfile cannot be flashed directly using the QFIL tool as it only supports.xmlfiles. - You will need a specific tool to extract the
.OFPfile. After extraction, you will see all the necessary files. - Remember to replace the
.elffile in the firmware folder with the one you downloaded earlier.
Step 7: Load the Firmware and Start Flashing
- Load the firmware into the QFIL tool.
- Click on the Download button to start the flashing process.
Conclusion
- After following these steps, your OPPO A3S should be successfully flashed without requiring authentication.
Note: Make sure to back up your data before flashing, as this process will erase all data on your device.
Good luck!
