I just rooted my nexus 6p and installed TWRP custom recovery, and instead of letting be read-only root, I let it modify system settings. I then looked at the superSU thread and it said to keep root as read-only. Is there any way I can make it read-only? Also, if I were to update my phone by flashing factory images since I cannot take OTA’s, does the fact that I allowed TWRP modify system settings prohibit me from flashing factory images?
