[Windows Phone 8 General] papersing:
Hi, my Lumia 925 stopped working without doing anything (no upgrade to Windows 10). It behaves the same way as described here: black screen, nothing happens if you try to soft-hard reset, however if you plug it to the computer it is recognised as QHSUSB_DLOAD.

I tryed to do the Thor 2 first step (I downloaded hex and mbn files from lumiafirmware.com for my RM-892 Lumia 925), but I'm already stuck:

C:\Program Files (x86)\Microsoft Care Suite\Windows Device Recovery Tool>thor2 -mode emergency -hexfile C:\lumia\FAST8960_CATWALK.hex -mbnfile C:\lumia\RM892_msimage_v1.0.mbn -orig_gpt

Built for Windows @ 13:36:46 Jun 16 2015
Thor2 is running on Windows of version 6.2

Can anybody help me? I've read that many people with my same smartphone solved the problem, but I don't know what to do. I tried to use the bin file provided in your blog (xdabloger.blogspot.it), after converting it to hex, but it didn't work either:
