Hello guys, can someone help me? I have an HTC 8x Unbranded i believe its a European unlocked device. I looked for the number you were talking about in the back of the phone and it says CE0560. I downloaded yesterday the update for Windows Phone 8.1 Update 1. It usually took about 6 hours in the update for GDR2 and GDR3 so I left it installing before i went to sleep. This morning I woke up very excited to use my brand new OS Updated and i was very happy when i saw those new icons on the top of the bar and when i unlocked it i saw the message that the update was succesfull. I couldnt be any more happy, so I started right away to explore and make new configurations such as Action Center and Start Screen Background. Finally i looked up for that feature we all have been waiting for: Cortana. I couldnt find it but I wasnt worrried as i read that I should do some configuration changes for the region and language and so I did. After making sure everything was right, I rebooted my Phone and surprisingly my phone didnt come up! After the HTC White Splash Screen i was hoping to see the usuarl Blue Windows Phone Screen but it just stuck in a Black one. I did power it down several times and did a soft reset with no success. Battery was almost charged as i left it all night plugged in. I tried connnecting it with a USB cable to my PC with no success. Im desperated!! Can someone help me please??? Appreciate!
