I have a problem with my camless E51-2 Mobil which comes only in silver color. I have German language installed but I want to have Turkish Language instead. My firmware version is 151.34.20 but I cannot upgrade it to 201.34.38.
As I was not able to find the product code for Camless version (RM-426), I have used "PC: 0554329: RM-244 CTR EURO2 Turkey SILVER" with NSS. After having changed the product code, I used NSU to change my firmware. But software says there is no software upgrade for my phone version.
I think this may be because of not knowing the true Product Code.
If I am wrong and I also can update with RM-244 Product Code, where do I make a failure.
