You can just always get the code by double tapping the image of the file you want on your idevice. Just tap it from the home page(not the specific shield page) like how you would tap when you're playing Flappy Bird. Make sure that you hold it by your second tap though. And then press copy, go on Graal, press paste and the shield code should be there. Works great, and no effort lmao. Tell me if the tip works for you!
