It sounds like a registry problem, (HKLM\init) Changing the values here will cause similar problems, The only way to recover the device is to perform a hard reset, if that's not possible, and a lot of the time it isn't, then a firmware flash will hard reset it, but the files are hard to find at the best of times, and sometimes the hardware looks for a digital signature within the image so only the correct image will flash.
Did your friend give any explanation as to why the device doesn't boot?
