Depending on where we landed, I would try to find my country's embassy, try to go to the nearest city (probably by asking people i encounter), or go to my family's country and visit while I'm there. I would just hope that if we're not in a city or town that we don't come across any lions, hyenas, or poisonous things.
I can see non-African INFPs or INFPs who possess a stereotypical view of Africa assume that either the land is practically uninhabitated and we must learn to survive on our own or assume asking the only help Africans can extend to us is to teach us to hunt and gather, after all, isn't that the native way of life for Africans? In reality, any isolated groups of people living any sort of ancient lifestyle and who possess no knowledge of cities is rare in Africa. Hunting and gathering isn't the traditional way of life for all Africans, and in antiquity, many kingdoms, empires, city states, and powerful businesses flourished in Africa. Ancient buildings of knowledge (libraries, etc), wealth (tombs of royalty buried with their riches), among other remnants of a history that defies many stereotypes about Africa and Africans.
