Best way to tame a bronto on Mobile. Gather a few hundred mejoberries or crops (rockcarrots,longrass. Etc.) trap the bronto or make it get stuck on a stone building constantly hitting it. Trapping is better since it cant get away when you tranq it. After trapping dont tranq it yet punch the bronto and go sleep near. After waking up kill yourself using campfire punch it again sleep. And knock it out put the food in it . Done he will be starving dont wait too long after knocking out
