Your phone has been successfully flashed with a custom recovery called TWRP and the recovery should now let you flash various custom developments on your phone.

These custom developments range from a single boot animation to a whole customized version of the OS that you can flash on your phone. Well, if you do not yet know, these are the actual tools that let you fully customize your phone and let it work at its fullest powers – these powers were behind the curtains so far as your manufacturer wanted you to be under limits due to some reasons.

Now that those limits have been removed, you can go ahead and get your phone flashed with whatever custom file you find on the Internet – but make sure you choose a file that is from a trusted source and is in working condition or in the worst case you will brick your phone.
