@arubislander Thank you, this worked! And thanks for the correction, I tend to mix the two up from time to time.

I recently installed Ubuntu Touch on my Fairphone 4, and I'm trying to reinstall Android. However, when I try to boot into recovery or fastboot to reinstall it, it doesn't work. I've tried power and volume up/volume down, but neither worked. It just shows the warning message stating that the bootloader has been unlocked, then boots into Ubuntu, no matter how long I hold any of the buttons. I've also tried using "adb reboot fastboot" but the phone turns off and does nothing while the command just hangs. Is there something else I need to do to boot into recovery?
