Thank you so much for this fix!!! I have re-installed my OS several times trying to figure out what the issue was. Question, is the problem related to the device itself or the drivers used by Windows?
I didn't do any unlocking but installed numerous beta OSes. I have a 9530 and this started happening after I installed the beta OS 0.90. Is there anything that I should avoid doing in the future to prevent this from happening again (I guess it really doesnt matter too much anymore since the tool you provided can fix the issue very quickly)?
