I had recently upgraded a Lumia 928 to 8.1, but was having issues with exchange email. I wanted to reflash the ROM on it (like I have done a hundred times)... but this time the app crashed and it happened early on. The phone is no longer responding to anything I do. I have tried soft resets, hard resets, etc with no luck... it seems toast. I am guessing the bootloader is hosed, is there any way for me to fix this... could a shop fix this?
One other thing to note... when I plug it into a PC I see the QHSUSB_DLOAD device with no detected driver
Thanks in advance
