Same thing, SX Inst crashes the system so have to hard reset. for tinfoil 2.2 I get the error "tinfoil.io login failed!" but then it does let me use the app.
I read in another thread it may be link to our time (clock) being inaccurate due to not syncing to correct/live time when in aeroplane mode.
Any news?
I had my card reformated to fat32, only the needed stuff in the SD, and SX Installer 2.0 still crashes!
Error 2168 0002
EDIT: FIXED! You have to open SX Installer when connected to a wifi network, once at least.
