fastboot provides two methods for rebooting a device into the bootloader:

  • fastboot reboot bootloader
  • fastboot reboot-bootloader

How (and whyy) are these two commands different and when is it appropriate to use each?

  • it is just because some developers did mistake, only one of this works it's different between phones

  • It looks like different references give different commands. I would suspect that the hyphen is a typo. Have you tried them both ? Commented Jan 6, 2023 at 11:16

I found an answer to this question here. To quote from the source.

reboot : Reboot the device.

reboot-bootloader : Reboot back into the bootloader. Useful for upgrade processes that require upgrading the bootloader and then upgrading other partitions using the new bootloader.
