Well, I just tried to upgrade to .167 and .151 on my 9530 with no luck. Once the system files uploaded to device and reboot. It displays error 507 then the DM / loader.exe operation stopped. Then I had no alternative but to re-install official .148. I really don't know what went wrong. Got the 9530 for 3 days but still unable to upgrade to desired ROM so not gonna able to use for fun.
