My brother (17) Bought a pre used switch off his friend (Screen only) starting with XKJ7 , which is V2 obviously but just for the fun of it we tried to boot into atmos on it and it worked without any issues as if its a V1, On most serial checker websites XKJ7 is either not a prefix or in the orange zone but everyone on this sub has reported XKJ7 isn't mod-able except for one other lucky guy on reddit who apparently has an XKJ7 modded switch, he asked his friend is he installed a modchip and he says he bought it fresh and never touched it more than twice (evident from the hours he had on and that the switch still had a plastic wrap on it) so, how is this possible ? are there very very very few number of hackable XKJ7's?
