I have a Droid 4 which I rooted to be able to use a tethering app, but I recently got an update for my phone, and I mindlessly updated it without knowing the repercussions.
I still have superuser on my phone, but no root access.
Should I be fine just rerooting my phone? If not, how would I do it safely so I don't brick it. (I forgot how I rooted it last time, so please point me in the right direction)
