I am grateful for all who tried to help me I just wanted to till that I went to carlcar " the maintenance agency for the phone " They updated the firmware and the message appeared again at the first time. When asked about it, they said it was a normal file. Previously it wasn't complete updating the file because it can not get the validity and that this is among the reforms in the update.
Note: I do not know why when I installed this version did not work with me. I couldn't be able to get a copy of the firmware from them but they are forbidden to give it to me generally, they are working on a strange program of their own I have not seen or heard about before.
