After the V1 got a revision, RCM jig was no longer an option. We now have hardware mods to exploit all handhelds after the v1
EDT: RCM was an exploit utilized to leverage tegra chipset. Chip was changed and so was the attack vector for exploit.
I did some quick searching and found that using a mod chip is the way to go in that case. Hardware mods are assumed to be via the mod chip if that is what I am getting through the searching.You need a modchip if you want to have CFW on the switch lite.
