Hi roman4a0 !

You can make by yourself the official ROM for your phone. You can make by yourself a full working firmware. I suggest you to make a Factory Reset before starting to make your firmware/backup. You will to have to keep this firmware/backup carefully. If sometimes you will brick your phone (soft brick), you will can restore it with your newly created firmware/backup. Soon I will suggest you a better way to make a full working backup/firmware, but at first you have to follow step by step the next great tutorial :

Thank you very much

The problem is that my original ROM have not, WHEN Install CWM recovery As . Much had changed since my cell . That is why I am asking the Official rom , or one that functions well

Now I have a ROM Backup, made with CWM. But it is not original is modified. as it had done previously without saving changes the original copy. The problem was I did not know how to do it until you install the CWM.

Hi roman4a0 !

The first thing to do when you buy a new phone is the full backup.
Do you have already tried to make a Factory Reset in recovery mode with CWM ?
At first WIPE CACHE ... and then WIPE DALVIK /ART CACHE ... and then FORMAT DATA ... and then FACTORY RESET.
