I have the no command error, but my volume buttons are broken so I can't get to the boot menu to fix

[Android Central Question]

Title. My volume buttons have been broken for a few months but that hasn't really been a problem as there are several apps that allow me to adjust volume without them. The problem is that I now have the error with the dead robot picture above a message saying "No command". I know usually this can be fixed by going into the boot menu by pressing power and volume up. But as I said, my volume buttons are broken so I can't do this. Is there another way to fix it? I would assume there's something you can do which requires plugging it into a PC with a USB but I'm not really sure where to start.

Thanks.

If it's necessary, it's a Blackview S8

Install adb on the PC. Install the driver for your phone. Connect the phone. Go to a command prompt (Windows) or terminal (Mac or Linux). Issue the

adb devices

command. It should show a device (a serial number). Issue the command

adb boot recovery

You'll be in the recovery menu. Now the problem is moving the cursor up and down - which requires the volume keys. So the best bet is to get the volume keys fixed first - then you don't have to worry about any of this.

(If you can wipe the system cache from Settings [some manufacturers remove that], it does the same thing as wiping it from the recovery boot.)
