Hacking Tutorial to CFW with Cobra on 4.86?

[Reaga]

Research seems to be questionable so far. Most places claim 4.86 is possible, but tutorials found so far are for old versions of the exploit, or include dead links.

Do we have an up-to-date one anywhere to achieve the above? My slim is a CECH-2001A, and while my old setup involved Ferrox Cobra I believe Cobra is the only required part as I intend to use the PS3 for PS2 emulation

Edit: Nvm, I found one. I usually don't do youtube tutorials for hax but MrMario seems reputable.
