LOL!! I was already crazy before
What really gets on my nerves is the Barcelona's shield xD ...but hey everyone has a taste for a team
...AHAM. my flashable zip files are easier to use than this method even you don't need to manage any kind of file (It's really dangerous if you are a noob and you don't know what are you touching )
I think my flashable zips might work without root too, but I didn't test it. It contains a simple lines that don't require the full installation of Buxybox, so it should work
But, your flashable zip just same like I mentioned a link for you. .
I think there is a bit difference is your title remove lock pattern and password? The pin is available or not? .
You need manage back name and rename like this, How to remove lock pattern, password and pin from your device.
And you also tell anyone for install it without root. . I think your flashable zip it work without root too.It's this for all android devices?
