The problem is that I can't restore the phone to the original state (that worked) because i haven't take backup.
I flashed the phone with (R3511_G_0A.52.26R_PDS00D_LP0004_DRM0201_JPJAVA_G_ 0).And it doesn't work.
And I'm obligated to try with something else.
I hope that the quadband resolve this.
I think tha is a physical problem on my phone.Because I tried many of monster pack but now there is a new problem.The signal strength is very good and operator name (Vodafone AL) is present but I can't make any call.
