I want to change CSC (region) of galaxy watch LTE SM-R805F in order to install samsung pay. I have searched two ways to do this: 1) dialing my IMEI number and 2) flashing combination firmware.
My concern with the first method is that after changing CSC, will i be able to restore the original CSC (region) using the same method. This is required because my mobile carrier will be supporting the original region only.
If i go with second method, would the above be possible?
