No internet connection / Doesn't accept PIN code on reboot

[kai24768]

Good morning. I own  a brand-new (bought last week) Z1 compact running on Android 4.4.2. Until yesterday evening everything was fine. Then I connected it to the recharging station, to find this morning that the internet connection was lost. As I didn't find any mistake in the settings, and from PC experiences, I shut down and restarted the phone. On reboot it asked for the PIN code. I keyed in the code given to me by the vendor (Deutsche Telekom) and which I hadn't changed. The phone replied that the code was wrong and allowed me only two more tries. Before doing this I guessed it might be better to ask the experts. I am sure that no one manipulated the phone last night. So what should I do, can you please help me? I'm a bit at a loss. Thank you in advance.

In these situations the only thing you can do is perform a system repair which will factory reset your device and also means that any and all data will be erased - Use either PCC or SUS found here - For PCC unplug your phone from the Pc and fully switch it off - Start PCC select Support zone then Update my phone/tablet then in Blue select Repair my phone/tablet and follow the instructions - Remember that when prompted hold volume down and connect your USB cable - Your phone should be switched off - In some circumstances you may need to perform this twice as the 1st time will install the Flash driver
