no, it could be a number of things.
does anyone have the 30b ril?
also is this 30b, different from the 30bEU and the 30bEU (Nov) ? its the november one right?
in getril the 20121130 is listed as v30a (thats the platform right) like v20 and v10. isnt there a b?
You can see a V30B German RIL in the general section posted by mark_hatred but I think it does not match(atelast for me it did not match)
But, just use what GetRIL shows as V30A.....I can tell you that it works
