How to enter Recovery Mode without USB keyboard?

Question

At boot, I know you can enter to Recovery screen by holding shift. However, I don't have access to a usb keyboard for now. However, a bluetooth keyboard is configured with my Raspberry Pi 3, but it isn't connected right away at boot screen.

Anyway, how can I have access to recovery with only a bluetooth keyboard / no keyboard at all?

Thanks :)

Answer 1

You can use forcetrigger. From the NOOBS readme:

If you are unable to use either the GPIO or keyboard to trigger entering Recovery Mode, you can:

1. Append forcetrigger to the argument list in the recovery.cmdline file which is found in the root NOOBS directory.
2. Reboot.

Note that with this option enabled, the Recovery Mode will be displayed every time you boot from your NOOBS card (until you edit recovery.cmdline again).

You can edit your the recovery.cmdline with the following:

sudo mount /dev/mmcblkOp1 /mnt
sudo nano /mnt/recovery.cmdline
