First I have updated to 6.1.1-15101 on Jun's 1.02a (which is working without any problem), but when I installed 6.1.2-15132, the process finished in recovery loop. I had the same result with Jun's  v1.02a2 and v1.02b.  I suggest using Jun's 1.02a on Gen8 Baremetal, and do not update to the latest version.
