maybe someone can help me or at least talk to me:
I purchased a new, sealed and locked I8190N in Germany, from TCHIBO Mobil. They are subproviders in the network of O2, j4yi.
To use the phone with another provider, I purchased an net unlock code from Ebay. I received the codes (NCK and SPCK) after some days from the seller, which do not work for me. It says something like "problems while running unlock process". Unfortunately the seller is an imposter, as he does not give me refund even I was able to show the codes he sent me do not work. But this is another story.
My question would be: Is there a stock rom I can flash to my phone? I checked my phone, at the moment 4.2.1 is installed, with I8190NXXANA1 as baseband. The last hint could be unlocking it at a phone dealer shop in town, because I was told unlocking with cable is more likely to help if code does not work. But who knows... I'm used to flashing mobile phones, running CM on my Motorola Defy all the time. But with Samsung and the special NFC version I got, I do not know wether I can use CM I8190 (without N) for my phone. Or if I should unlock it at a dealer somewhere in my town before starting flashing anything.
Thanks a lot for help and reply!
