I decided to try again.

I removed everything except wp-config.php and the wp-content directory.

Uploaded the 3.1.1 files again, and this time it worked!

what is the content of index.php?

I have been trying to update a blog from 3.0.4 to 3.1.1 and getting nowhere with the automatic updater.

I replaced the wp-admin and wp-includes directories, and updated the remaining files, and then I got a blank page.

Replace the old wp-admin and wp-includes directories and it all works fine again. Good job I renamed them instead of deleting!
