Step two - Hold your finger down on your Minecraft apk, it should then be selected. Next go back to that menu and click 'extract to', now a menu should pop up and then choose 'choose path' and another menu pops up, find your downloads folder then open that folder you just made "0.13.1 minecraft pe". Now push 'ok'.
Step five - Go back to your downloads and then into the 0.13.1 folder, select everything and go to the menu and press 'compress'. Wait for it to finish compressing and it should make a new file, now select that file and go back to the menu and push 'Move to' and go to your downloads folder and press 'ok',
Step five - You are almost done! Now go to the ZipSigner application I told you to download. Select 'choose in/out' and select '0.13.1 minecraft pe.zip' now push 'sign the file' and wait for it to be signed.
Step six - Go back to ES File explorer and go to your downloads folder there should be two zip files "0.13.1 minecraft pe-signed.zip' and '0.13.1 minecraft pe.zip' Delete 'minecraft pe.zip' and select the first one, at the top there should be an uppercase 'i' select it and it will allow you to rename the file. Rename the file you selected (0.13.1 minecraft pe-signed.zip) rename it to 0.13.1 minecraft pe-signed.apk (It is important to have the .apk at the end, that's the only change needed)
Step seven - You are done with Zipsigner and ES file explorer, now you should close both and go to your app menu, somewhere on your phone you will have something called 'File Manager'. Open that and go to "Applications". In that folder '0.13.1 minecraft pe-signed.apk' should be there, open it and install it, now open Minecraft and there you go! Minecraft is updated with a new texture pack!
