This video on Youtube (published March 2015) is showing same problem that I have. You can see in the comments that still this problem is going on.

see article about Easy JTAG on internet.  you can understand how this begin and end.
Rolling back to old os may be difficult. So you can try custom os. But if you need stock rom back try fastboot rom. Check whether fastboot rom is available for you. You may want to use tool to do that
