fixing com.android.Preconfig not found

Hi,

I'm trying to change my i9300's original CSC from Cel (Cellcom Israel) to ILO (Israel withuot Cellcom).
In the process, but it keeps failing in every method (using *#272*IMEI# / CSC Changers / Terminal) due to the same issue:

Code:

---

com.android.Preconfig not found.

---

i tried doing this http://ift.tt/22WNDnB but it failed, leaving me at square-one

is there a way to get the missing file and copy it to the phone?

thanks in advance
