I started studying what the causes of this could be.
Baseband is shown as "unknown" and when i put *#06# IMEI says "null/null".
Now I suppose it is a problem with the files in the EFS folder.
When i open nav_bin file with hex editor it is all blank, all the fields have "ff" and the last ones "00"
I need to restore the EFS folder in order to have at least a generic IMEI, isn't it wright? How can i manage to do this?
I don’t have any backup of the original files; anyway i don’t care having a generic IMEI to begin with.
Any help is appreciated
