Yes.

If something goes wrong the service processor should switch to the other
flashside. There you can then enter "update_flash -r" to "reject" your
flashed image. That will copy the backup (permanent) image to the primay
(temporary) side. With "1 set-flashside" you can toggle back to the
temporary side and reboot the system. Then everything should be as it
was.

The command ".flashside" will print out on which flashside you are
currently running (if you want to check).

Sometimes the service processor does not correctly switch to the other
flashside if the first is broken in some way. After powering off the
system and back on with the white button (without pulling the cable) it
then switches the flashside.

If the firmware hangs during the initialization of the graphics card it
helps if the card is removed and then the previous version of the
firmware can be recovered.

Of course it still can break in so many ways, but I have always been
able to recover using the permanent side as a backup.
