assuming that the brick code runs constantly and performs the "verification" checks at random, simply delaying shutting down would increase the odds, the whole thing about shutting down, is that right now the "brick code" could of already done its dirty deed, you just won't know until you reboot, so it's a sort or ....test your faith moment or just live forever in emunand and run from charger to charger and pray you never crash

But the actual odd's of being bricked are very slim under the normal circumstances, just go for it and replace your launcher
Diagnostics is where the really bad dangers are
, but I still don't suggest you tempt fait as another user on max console claims to of been bricked without ever running diagnostics
