u/I-HLAK-I

I haven't used my switch in a while and i did all the things to update my firmware correctly but i found out that most of my apps aren't working because they're an old version. Is there a way to update all of it at once, because i remember having a telegram page that gave me a link for a file that contains all of the necessary apps on the latest patch.
(I looked on the wiki and couldn't find anything)
