That just sounds dangerous. Isn't it better if Tinfoil got updated instead?
to quote TX verbatim
“you can use choijournx if you wish now, it will still brick, but you will not notice it. it corrects the error, the only issue choidijournx had is it wrote some info that only compatible with erista switches, we remove that info and replace it with the mariko info, so your system can bootup normally.”
He was asked well what if it were to brick brick?
“yeah worse case, but once you run v3.0.3 on your switch you have the update added, no need for ext. tools”
