Im sorry im kind of a Duma$$ ok? have that in mind and be merciful, i fail to understand a lot of this, i have done both jailbreak and downgrade a lot of switches in a lot of variable versions of the OFW and CFW and never hear you need a specific version of it as long as its not of the new ones, now i DO NOT have idea whats the lowest version you should downgrade a switch, so, what specific jailbreak are we talking about? I also never understood people who makes fun of other people who doesnt know the same technical stuff as them, like, i have a degree in english literature and language and i dont make fun of people who doesnt know english at all, I find it quite chauvinistic.
