Upgrading to Official FW

[penti]

Hi, I have a Samsung PS64D8000 and I upgraded my FW to the custom one found here, but I forget since this was almost a year ago. I checked the current FW installed and it says T-GAP8DAAC-1017.0, BT-Q / G. I mainly did this so stop the brightness popping problem found in earlier FWs. Now, I want to upgrade back to the official FW so I can get the new apps available. How do I do this without bricking my expensive TV.

Thanks!
