this might not be too much help. i wasn't ware of particular issues on the Nigerian border. you can get a visa at the border but it is only valid for a very short period (2-3days) which you have can extend in cotonou. (this may only be possible at larger borders). i would recommend getting one in cameroon, if possible. just saves you the hassle of 2 stops. as well as any potential 'extra fees'!
hope this is somewhat helpful.
people feel free to correct me if i'm mistaken
