If the solution doesnt work for you, doesnt mean its fake. There are others who are able to downgrade with this solution. If you happened to read from page #1 to the last, theres lots of evidence of others successfully downgrading.
It doesnt work for me either when I have tried so many ways of doing it and repeatedly. There could be so many reasons why for those who are unable to downgrade. Hardware issues, software, country IP, eye-sight, brain etc etc.
So please dont condemn the thread with "fake" when the solution dont work for you. People trying to give solutions in order to help others. Please atleast give some respect for their effort.
Im sorry if this offend you in anyway.
