http://forum.xda-developers.com/showthread.php?t=1062918 Hi Brother, Here is solution. Windows Phone 7 handsets stuck in USB Host Mode This looks like it's common to all WP7 phones, not just the Mozart but it's particularly annoying here because you need to feed the Sim Card/Flex adapter under the battery, over the battery retaining clip and under the battery cover. Very fiddly. Very easy to accidentally press the power button. IF YOU PRESS THE POWER BUTTON INSTEAD OF VOL DOWN + CAMERA YOU WILL SOFT BRICK THE PHONE. IT WILL BE STUCK IN USB HOST MODE. Fortunately to fix the phone you just need the "special cable" with MicroSD reader from the WP7 upgrade kit, the Gold Card you make in step A and the firmware for the phone you're working on. 1.Take the firmware .exe and extract the largest file (Ruu_signed.nbh or something similar) 2.Rename it using the same 4 letter naming convention that the DIAG file already on the goldcard with a IMG suffix e.g. MOZAIMG.nbh 3.Copy it to the MicroSD. You can use the XTC Clip as a card reader. This is the slowest part of the procedure. 4.Delete the DIAG file 5.Put the MicroSD card in the "special cable" and plug it into the phone without pressing any particular buttons. This will automatically reflash the phone with the possible bonus of debranding the phone. 6.Once the phone has booted up, you can proceed with trying to unlock it again. Hope this helps.
