I have installed the 8.1 Preview for Developers, and by that momento Nokia Black update wasn´t available on my contry/operator, so it was installed over the Amber update.
Now, Black update is available for my device, but it won´t install. My country is Argentina and operator is Movistar.
Is there a way I can install the black update without flashing my device? since I don`t want to reset my phone.
Thank you very much!
