TOday i've received the notification of a new security update on my moto g turbo. My phone is root and I've a couple of frozen system apps. Can I just say yes to the update? or do I have to unfrozen and unroot? is it possible that this update fixes the flaw that allow us to root? thanks.
Moto G turbo 2015 - new security update this week. Is it safe to install?

If you have rooted your phone, you shouldn't apply any OTA update because you can brick your phone, as far as I know.
No... It is not safe to install. OTA updates, even simple security updates, cannot be installed on a device that is rooted or modified in ANY way, it will softbrick and if you don't know how to handle that then it can be very frustrating.
Either ignore the update or restore back to pure stock, take the OTA update, root, and setup like a new phone. You could potentially use TiBu or UltiBu to backup and restore, but I usually find that causes more problems than it solves.

No... OTA updates cannot be applied without factory recovery and /boot and /system unchanged.
Is there an option in twrp or CWM to save all user settings/programs/files, apply the update, and then restore those?
No... But you can do a full nandroid backup in TWRP then extract the data you want with Titanium Backup. Again, I do not recommend this method, setup clean is much preferable.

Certainly starting again from 0 is unbelievable bad. It's a pain in the ass do it all over again. I will keep my phone without the update or I will find a way to unroot, apply the update and then root again.
What's the best way to do a complete backup with user files and everything, I mean evertyhing, of the phone before I try this procedure? in twrp or cwm?

Well... Even if you unroot and fastboot flash stock recovery, it won't undo any changes to the system, most people who attempt this fail and leave their device either unbootable or not updateable. BTW, if you had a custom ROM none of this would be an issue because updates to custom ROMs are designed to work with TWRP and customization. Unfortunately, with how Google has implemented security changes and checks, updates on Lollipop and newer Android cannot be applied to modified devices.
Here is my opinion on this, and it is not always liked:
If you have an Android device, especially if it is a modified one, you should ALWAYS be ready and willing to reset it at any time... Use Google Photo or some other cloud based app to maintain backups of pictures and videos, perform regular cloud backups of SMS/MMS messages (SMS Backup & Restore is great for this), perform regular backups in TWRP and with TiBu or UltiBu, and always enable and use Google's backup service and maintain file copies on a microSD card, PC, or other cloud storage... personally I usually do this weekly but that is because I make lots of changes to my device. There are also many tools that can automate this process, such as Tasker.
Additionally, I see little to no advantage to rooting a stock device, a stock rooted device has immediately been limited in regards to updates, with older devices this isn't an issue because updates are done, but on newer ones it is a serious pain. Stock and rooted is a waste of time... if you want to root you might as well go ahead and flash a custom ROM, otherwise leave it pure stock without root. This may seem an odd statement from a guy who has written several rooting tutorials, but it is my view on this.
Again, this is my opinion... if you modify, be ready to lose everything at any time, if you are then this isn't an issue, and if the worst happens, like you drop your phone in the river or smash the screen, or you just get a new device, you always have some source for the information to restore back to a device.

TWRP has a backup tool, use it... you can restore to that exact point at any time, it's called a nandroid backup and is a dump of each partition of the phone, restoring it will essentially bring the phone back to that exact moment in time. Remember that the default save point for this is on internal storage, which can/will get wiped, so save to the SD card and/or copy it off the device.

Let's say I go do it... What's the best steps to do it?
1) nandroid backup
2) restore original bootloader??
3) unroot? how?
4) install the update
5) replace the bootloader
6) root again
??
The bootloader is not relevant, /boot is your boot image (kernel) and it is what is modified when you root, /system is not touched by systemless rooting itself but almost everything you do with root access (like Xposed or debloating) modifies it.
Unrooting is done inside the SuperSU app itself, note that this does not undo any changes made to /system with root access, it just removes the su binary, SuperSU app, and undoes the changes to /boot by restoring the stock image.
The best way to do an update on a stock, rooted device that I am aware of is by following the tutorial I linked a few posts earlier.
