Educate the populace is not going to work in the short term. What a lot of sub Saharan African countries need right now is a benevolent dictator/king. Strong emphasis on the benevolent part, someone truly looking to improve the countries and their populace. This person needs to put in strong rule of law and build out institutions and crush corruption. Once you have a stable working order, that is a much better time for democracy to be re-introduced. This is how most countries in the world were formed. Unfortunately due to colonization and a later progression, Africans were never able to complete that part of their development cycle.

That being said finding a benevolent dictator is easier said than done. I can’t really think of anyone that has fit that bill over the last 75 years in Africa, the closest might be Paul Kagame in Rwanda.
