Its highly Recommended before modifying system or rooting to do a NANDROID backup!!! (YOU SHOULD DO IT)

On the HTC One M9, any changes to system will cause OTAs to fail, its confirmed by the updater-script. The first thing everyone will need to do before flashing ANYTHING is make a backup of system.
TWRP for the M9 is set up to mount system as read-only to prevent any checksum changes. Any backup taken of system is done via dd, which means the backup is done in image format and should exactly match the original check-sum if/when restored.
