OPPO requires “Deep Testing” approval for bootloader unlock on this model.

OPPO requires an authorized deep-test account. Official unlock is unavailable for many regions; engineering builds may allow fastboot flashing unlock . Without bootloader unlock, TWRP flashing is impossible.

Download the specific TWRP image file ( .img ) compiled for the OPPO A5 (2020). Ensure the file matches your exact model number (e.g., CPH1931, CPH1933, CPH1943). Rename this file to twrp.img for easier commands.

Re-enable on your phone (since the bootloader unlock factory reset your settings).

Go to -> Version and tap Build Number 7 times until it says "You are now a developer."

To ensure the phone boots normally without security triggers, download a vbmeta.img file (usually provided alongside your custom recovery package) onto your PC. While the phone is back in Fastboot mode, flash it using:

Unexpected shutdowns during flashing can be fatal for the device.

Type cmd in the address bar of the file explorer and press Enter to launch a Command Prompt window inside that folder. Execute the following command to verify your connection: adb devices Use code with caution. Authorize the prompt on your phone screen if requested. Boot your phone into Fastboot mode by running: adb reboot bootloader Use code with caution. Verify the fastboot connection by typing: fastboot devices Use code with caution. If a serial number appears, your device is ready. Step 4: Flash VBMeta and TWRP Recovery
