Hello everyone, I am in need of a backup file for build.prompt..

I tried to change my phones DPI.. and now it is stuck at the boot screen..

I also had my phone rooted, but I thought maybe hard resetting it would fix the problem.. so i am not sure it is rooted any longer..

if anyone could be of help, it will be greatly appreciated

 

If this is not feasable, could anyone share a method to completely reset my phones core data?
