Hello tcecyk
thanks for giving me new approachs.
For the solution 1, well, I don’t know what to looking for, there are 11702 lines in the file … 
For the solution 2, well, I could do this, but you may as well say that e.os is broke.
And maybe it is, after all.
I really need all (well, almost all) functionalities of my phone, and I need software solution for this kind of sh*t, I spend my life to resolve experimental electronic and computer problems in my work, I just refuse to do this all my life !
I don’t understand why functionalities like this are not implemented yet.
But, that’s not your fault, I’m just think with my keyboard (^^) and again, I thank you for your answer !
bye
