I've got an android phone running Android 6.0, with
SuperSU installed on it (Not systemlessly though). Before I changed anything on the device, I temporarily booted into TWRP and created a
Nandroid backup of all the partitions.
My device has now received an OTA update to
Nougat 7.0, so,
Would restoring the system partition in TWRP break anything? or would it just restore my device to stock Android (allowing the OTA update) with all my data intact?
