SOLVED: Crashing upon boot with logo only on the screen

Hello, guys, I'm having troubles from the very start: got Z10 2 hours ago, installed two apps and then I tried Google store (now I know the wrong way) and I ended up with only logo screen with unsuccessful boot. Can give me a piece of advice how to fix it (with FW reflash from USB maybe...)? Thank you, Richard, Czech Rep.

 

Followed the procedure from one of the older posts here. It worked eventually.

 

Hi there. I had the same problem, and the instructions for reflashing the FW didn’t solve my issue. What method did you use?
