i need help changing my boot animation. ive looked at tons of other sites and videos but none of helped. MOst are for windows and those cant help. i have downloaded the SDK and fastboot and put them into tools. i have also placed my bootanimation.zip in there as well. but this is where i am stuck. i dont know what to do when it come to running commands in terminal. adb never works for some reason. so can anyone help? i really appreciate it. a step by step guide would be great
