you can install CWM.
Then make a full backup. You can move it on your pc or let it take space on your phone.
After that you can apply any patches via CWM or install root or whatsoever
When your phone will show the next update you should:
1) Boot into CWM and recover your backup. BUT! You should recover only part of it. The system part.
backup and restore -> advanced restore from /sdcard -> choose your backup -> restore system
2) wait till it complete.
Now you can delete your backup.
Reboot your phone (reboot system now)
After that you will see 2 messages and if you wanna be able to apply ota you have to make the right choises
Q: ROM may flash stock recovery on boot. Fix?
Q: Root access is missing. Root device?
After all that steps you'll get:
1) clear system part (which means no root, modified files etc)
2) default recovery
