I've read this entire thread again, and I'd just like to note that this image does flash on my true Windows based M8. Maybe I'll try attacking it from the other side, and try loading android on it?
Earlier in this thread, a link to ACDU was posted
. I used that, and held both vol buttons on my M8 for Windows as I powered it on (don't start it with the USB cable already inserted, it doesn't like that for some reason). I'll record a video of the process from the Windows perspective because I have no clue if its similar to the Android side or not.
Restoring seemed to work perfectly in Windows 8.1, so all of my apps and settings came back right away! Since I don't have much to lose I'll do it again with video.
*edit* I slapped together a video
. I apologize for some of the editing, but some of my MIED info would have displayed otherwise. :/
I'd be willing to try flashing Android to it if I could change the model number on the phone itself. :/
