The last couple updates I have done with the N7, TWRP actually installed them. Breaking root and then TWRP afterwords. I had to pull up a program on the MBP (not sure what it is off the top of my head), re-root then install TWRP again. I have put off this new system update for quite some time now because of this issue (I am still on JOP40C). So, once more, if I install this update, will it break everything again?
