To Open Fastboot Mode On Oppo A37 Better: How

On most Android phones (Samsung, Google Pixel, Xiaomi, etc.), you enter Fastboot by powering off and then pressing Volume Down + Power. On the Oppo A37, this combination does nothing special—it simply boots the phone normally. Oppo has disabled the hardware key combination for Fastboot.

Instead, the “better” way involves using ADB commands from a computer or exploiting the engineering boot mode. Below are the two most effective methods.

Even after entering Fastboot, you will find that many commands (like fastboot flashing unlock) will not work on a standard Oppo A37. Oppo locks its bootloaders and does not provide an official unlock method for this model. You may see:

FAILED (remote: 'Device already : lock!)

This is normal. To truly fastboot flash anything, you may need an unofficial unlock tool or an older firmware version that had a vulnerability.

Final pro-tip: Before attempting any Fastboot operations, fully back up your Oppo A37. Fastboot commands like flashing a boot image can permanently brick your device if done incorrectly. Also, remember that unlocking the bootloader voids any remaining warranty (though for a 2016 device, that’s likely long expired).
