Use this handy software in order to modify your langpack. Very
usefull for correcting mispellings in the original langpacks like
"personaliSe" and "dialLing". You need to have Dynamic Prompts enabled
in your seem. You will need to use SHXCodec before start using this
software so you can extract the langpack and locate the codes of the
string that you wish to replace.
After you make your modifications you will need to upload the generated .prf file into your A drive on the mobile.
