Did it not from here but from another shop with tariff. My first Smartphone! Yes Hard to believe! But my old phone had given up the ghost. Initially a par settings, then had the pin number can be entered. Did it issued, open the battery again removed and plugged the card. Battery in and turned on again. Startup and then blue screen with negative Smiley. And then in an endless loop startup - bluescreen. Downloaded belongings in network Lumia Recovery Tool and installed. Hung Phone to the PC and tried to reinstall, but did not go. The download of the software has always remained hanging. Yes, with the SIM card has gone stupid but that immediately comes it to blue screen and nothing else will work so I did not expect. Have it as returns posted let's see when it comes back. Windows 8.1 is probably still quite sensitive but perhaps I am mistaken also.
