Well you didn't mention how you tried using the return result of undotree(), but there are at least four plugins useful for viewing your undo history. See http://vim.wikia.com/wiki/Using_undo_branches#Plugins

But if you somehow exited Vim without saving, I think the undo information you're looking for may be lost, especially with that E825 message.

:help E825 says:

*E825* The undo file does not contain valid contents and cannot be used.
