You shouldn't have a problem here. If it's just key 5, the updater
will unpatch it and continue just fine. If it's more than key 5, it'll
give you another error code and exit without doing anything. HOWEVER,
that said, always be ready with the Pandora Battery and a NAND
backup... just in case. There's always SOME chance things will screw
up and you'll need to restore the NAND. Those chance are VERY slim,
but not zero.

Seeing as you have the backup, I say go for it. :)
Like I said above, things will PROBABLY be fine. I have yet to
actually need to use a backup when messing with three different PSPs
of different makes over a dozen different custom firmware updates. I
just updated my brother's Phat from 3.52 M33-4 to 4.01 M33-2 and had
to face that same "Press X to fix keys" message. It went fine, and I
don't see why it shouldn't for you.
