I don't believe there will be ever a method to gain HENkaku on 3.61 since not only do you need to find new exploits, you also need to port over the addresses the exploit needs to use on that specific firmware. Downgraders are possibly out of the question too, since Sony dealt with a lot of issues surrounding fakesigning updates and stuff way back when PS3 and PSP hax were hot.
Furthermore, I would advise removing the scam link out of your first post; you'll just be giving them eyes in the ranks of search engines, if anything.
