You mean a method like this? https://forum.xda-developers.com/moto-g4-plus/how-to/xt1644-stock-marshmallow-to-nougat-t3540022
If you download the 93-14 Nougat firmware, that's the latest version. Nougat OTAs currently only exist for the 93-11 firmware.

Yes, your bootloader status won't matter - as long as that's all you've done. As I understand it, the update via stock recovery only cares if the rest of your phone has been modified - if you've still got a stock bootloader, stock recovery and stock kernel (from MM, provided it's up to date), it should work and you should be eligible for future OTAs.
The only hurdle I could see happening is that the build of Marshmallow expected by the OTA and your phone's current OS build do not match, in which case it won't install. Thus, you may have to consult one of the fastboot Nougat 93-11 or 93-14 threads to install, which you'll have to do if your system is modified past the bootloader.
Here are a couple for your perusal:

Thanks for the brief info, it means i have to flash it via fastboot and if that works fine then I'll be able to get OTA, but for your info, I've unlocked bootloader and installed Official TWRP but if i flash any of the firmware (given above) will i face bootloop kinda stuffs? I am scared if something goes wrong then i will even not able to restore nandroid backup. Hope you gotta help me.
Thanks.

I see you've received a response in the other thread regarding if XT1644 will accept the update; given you've flashed TWRP, if you wish to be very safe, I would suggest re-installing your Marshmallow ROM so you have a stock install before proceeding to Nougat. There's nothing stopping you from directly flashing Nougat, and the fastboot method for either Nougat build may correctly overwrite the relevant files, the only way is to try the procedure. Don't use the TWRP backup images of Nougat - they don't contain updates to your baseband modem and other core parts of your device - they are only meant to be used once your entire phone is updated to Nougat.
If you wish to restore back to stock MM before flashing Nougat, here's links to stock firmware for XT1644: https://forum.xda-developers.com/moto-g4-plus/how-to/xt1644-firmware-t3454980
But either way, read all the instructions first, ensure you've got all the firmware and tools you need installed/downloaded, your phone has at least 50 % battery and plenty of time, and you should be okay.

apply OTA to rooted phone?

i have an unlocked rooted but otherwise stock G4P and it has an OTA but fails to install. Is there a full ROM I can apply which won't wipe? Or some other way which is not involving a full wipe?

I tried, failed, and eventually gave up. I haven't had the motivation to do a full wipe/flash, but I tried everything else I could think of before giving up.

I had a twrp backup of my system partition, which I restored, then fastboot flashed the stock kernel, and wiped caches. Safetynet passed, but the ota would not flash. It said there was an unexpected change in the system, or something to that affect.
I'm not aware of any true, untouched flashable rom zip available. I suppose it wouldn't take long to make one, I just didn't have one available to me.

To install the OTA update the stock recovery is required, and Twrp is a custom recovery.... after restore the backup you should reinstall the stock recovery before apply the OTA.

sorry, didn't see you were asking about fastboot. no, I didn't flash the factory image. I didn't want to go that far and didn't really care enough to do a full wipe

Have you tried Magisk? Could potentially work

A TWRP backup restore doesn't fix the issue. You have to reflash SYSTEM , BOOT(if modified), RECOVERY(if modified), and OEM through fastboot. That is a "block flash," instead of TWRP, which is "file based restore."

What about other partitions :
gpt, bootloader, adspso, modem
Must they be restored ?
Just after OTA, is it possible to make a raw image backup with TWRP in R/O mode ?

You only need to restore SYSTEM, OEM, BOOT AND RECOVERY images. That's all you'll ever need. NEVER touch other partitions, unless you are upgrading.
To make RAW image backups of SYSTEM and OEM partitions, use terminal in TWRP
Or "adb shell" from your computer (running as root)
adb shell
ls -al /dev/block/platform/soc/7824900.sdhci/by-name
This command will give you the names of the SYSTEM and OEM partitions of your device, Moto G4 Plus. For example, for Moto Z Play (my device), they are mmcblk0p53 and mmcblk0p51 respectively.
So, the commands would be (again, that's an example for MOTO Z PLAY):
Backup
dd if=/dev/block/mmcblk0p53 of=/sdcard/system.img
dd if=/dev/block/mmcblk0p51 of=/sdcard/oem.img
Restore
dd if=/sdcard/system.img of=/dev/block/mmcblk0p53
dd if=/sdcard/oem.img of=/dev/block/mmcblk0p51

Thanks much VR25.
With your help, I have successfully applied the latest OTA

Confused. The VR25 guidance is when you had taken a full backup when stock, how to restore back to stock to then apply the OTA. You are describing how to apply the OTA on a rooted device without a pre-rooted backup?

You don't need backups to apply the latest OTA.
Get the stock corresponding to your device.
flash LOGO, SYSTEM, OEM, BOOT AND RECOVERY images.
Apply November OTA
Apply February OTA
I did that without wiping my data.
If you want to avoid reset to stock & apply all OTAs, you must have a binary backup of system partition, not a file based backup (see comment #8).

Exactly this question, but then the XT1602. Flashed the stock parts, but no message of an OTA and they are nowhere to be found. Or does anyone have latest stock version full ROM?

Yeah, others were just saying too high a level to not actually helpful. As I did this last week I'll tell you now is as step by step as I can to actually try to be helpful.
Firstly you need to know you will wipe data, there's no avoiding it, that I could find so backup everything, that can be a mix of TWRP backup of data to SDCARD external, USB OTG, or Titanium backup to online / SD / OTG. In my case I prefer to simply install everything and configure everything from scratch.
Follow this guide to return to stock.
In my case I'm on Ubuntu Linux desktop, fastboot got a "no permissions" type message so I had to sudo in front.
The stock for your device, well look at your device Status page now before you start, Settings -> About Phone -> it says Software Channel "retus" so when I go to the list of ROMs in the above guide go to mirrors.lolinet.com - firmware - moto - harpia - official - then I went to Retus, you'd go to a different one probably.
Note these are old stock ROMs I think from September so there have been one or two updates since then.
Follow the step by step guide, basically lots of fastboot commands.
The step where it says fastboot oem lock it bawks and say fastboot oem lock begin and that will do another wipe, so given a later fastboot oem unlock would do a 3rd wipe I didn't do the oem lock, I left mine unlocked and that worked fine.
Let it boot, setup, you will then be in an old stock ROM, then if it doesn't offer to do an update, go into Settings, System Updates, and trigger it to look. It will then download and apply a stock OTA ontop of the stock ROM. In my case it was 1 OTA, 1 update, then that that complete. You then are on stock current ROMs.
Then root and whatever you want.
But note, to get to the impending N OTA, you'll probably have to right back to the top here because your rooted Moto G4 Play will likely refuse the future OTA as the system is modified, so you'd have to repeat, return to an old stock ROM and then let it go through the 1 or 2 or 3 OTAs to get to that future release.
Hence you'd be doing the return to stock twice.
If the mirrors could be updated to newer stocks it would bypass the OTA. My other phone - the OnePlus3T they offer mirrors of full ROMs, they are far easier to use because if you are rooted you download the full ROM not just the delta incremental of the change of the OTA, and then you can flash in recovery the full ROM and it ignores the system state, and no wiping of data. The fact the mirror site is out of date is causing the need to wipe so the OTAs work on an unmodified system.
Fortunately I have multiple phones so I can use another for the few hours this all takes.

works great, I just flash it and without wiping data

Here is time to apply the may OTA MPIS24.241-15.3-21.
I restored the vanilla system.img MPIS24.241-15.3-16 with dd, but it didn't work. The OTA failed with the error "system partition has unexpected content" because the sha1sum was incorrect.
Here is the solution :
Before restoring with dd, you must check "Mount System partition read only" is enable in the MOUNT menu of TWRP.
With TWRP 3.1, you need no more to use dd. Now, the feature "system image backup" is available

Please backup first

My only question, why do all these people keep hard bricking their phones? Please, your first step after unlocking your bootloader should be a full Nandroid backup, and download of the stock recovery. That way you have the full stock system, kernel and recovery in case of any mistake, OTA, or any other reason to go back to pure stock. If you need to back to stock, restore your backup, then flash the stock recovery in fastboot. Boom, pure stock, able to accept OTA updates, no issues. Please, for the love of God, make a backup before you make any modifications to your phone. Rant over, thanks for your patients.

Can I also flash the same fastboot ROM on which my device was while on stock (considering I was on the latest update and was trying to flash the fastboot ROM of the same version) if I forgot to make a nandroid backup?

That should be okay, though be aware that doing so may erase your data in the process. If you need to, make a backup of your device as it currently is in nandroid/TWRP and move it off your device. That way, if anything happens, then you may be able to copy the TWRP backup back and restore your device.

Unfortunately, in the majority of hard brick cases, a backup won't save your device, as it's not the system side of things that causes headaches, it's the underlying bootloader.
The main reason is, from what I've observed, is users flashing either the wrong firmware for their device (e.g. US firmware on an Indian device or vice versa) or attempting to downgrade their firmware. Either method can leave you with a mismatched bootloader and system. OTA updates check what system you have for installation purposes, but appear to assume the bootloader is the same patch level as your system. (Should they check for bootloader as well? That check would go some way to preventing hard bricks, but appears Motorola assumes you wouldn't flash firmware not intended for your device or downgrade...)
Thus, because you have a mismatched bootloader and system patch level, you can run into hard bricks when users attempt to subsequently take OTA updates, especially with bootloaders updated to May 2017 or newer.
E.g. a user flashed the US retail NPNS25.137-35-5 with May 2017 firmware onto their device, but wanted to revert back to the Indian firmware. They flashed back to NPN25.137-15 (Jan 2017 security patch) without being able to flash the bootloader, since bootloaders do not permit downgrading of bootloaders generally, and especially after the May 2017 patch. So you have a May 2017 bootloader but a Jan 2017 system. The OTA update downloads and begins flashing believing that your system is Jan 2017 and applies updates to your bootloader thinking it too is at the Jan 2017 patch level too. Of course, it's not - it's May 2017 - and thus causes a hard brick.
The current resolution for hard bricks is blankflashes to reset the bootloader. The only other resolution is that users do not downgrade their firmware, and are very careful with what they flash, and only flash the same firmware as they had or newer firmware that is a direct update of their existing firmware. Alternatively, flashing TWRP images of stock ROMs may be preferable, as these images only flash the system side of things (like a TWRP nandroid backup), so do not affect the bootloader.

That's absolutely okay with me as I always like to clean flash ROMs and I don't mind the data partition being erased.

That is the point of having a backup. You don't have to flash anything in fastboot. You have your OWN firmware backed up on YOUR OWN DEVICE and don't have to worry about any mismatch issues.I have been rooting and flashing custom ROMs for 5 years on 7 different devices( this is the first phone I have not rooted...yet). The first thing I always do after installing a custom recovery is make a full backup. That way if I do something wrong, I always have the stock ROM to go back to. I firmly believe all unlocking and rooting guides should have this step included and not listed as optional but as required. This would help prevent a lot trouble from users flashing the wrong firmware on their phones.
For what it is worth, I have rooted and ROMed: LG Optimus V, Nexus 7 (WIFI tablet), HTC One V, Samsung Galaxy 3, HTC Desire 820, Asus Transformer TF101 (tablet) and Motorola Moto G3. On all these devices I had a full backup of the stock system.

I agree with what you wrote, a backup in TWRP and having the same stock ROM is essential to a safe and working device... A stock ROM is always useful in flashing the stock recovery and other stock firmware prior to taking an OTA update. With TWRP backups, you now have to be careful not to allow modifications before you take the backup, else the OTA detects the system partition is no longer readonly, if I recall.
Course, this would be much easier if Motorola/Lenovo released the stock firmware rather than having to depend on leaks, but I'm guessing they don't want to deal with users that flash the incorrect firmware for their device.

I have never flashed a phone before.
It seems I have a virus/malware that's inserted itself into the ROM on my phone. I perform a factory wipe and reset but the malware is there on the fresh install, redirecting webpages to a pop-up about Amazon or Walmart gift cards. Backing up the stock ROM seems not an option for me. Is it possible to download a stock ROM somehow?

Some questions regarding flashing the stock firmware

Hello, so basically when I was on the June update of my Moto G4 Plus, build NPJS25.93-14-8, software channel reteu, model XT1642 when I decided to unlock my bootloader and flash RR. Now I want to go back to the stock firmware for several reasons, but I have some questions about flashing it. I know how to flash it trough fastboot, but I have some other questions.
1. What are the risks if I flash it?
2. Can I just restore my twrp backup for the fully stock rom, flash the stock recovery and update to the last build through ota? will that work?
3. Will there appear other problems I have to worry about?
4. Can I just flash the June patch through fastboot so that I don't have to flash the updated modems, fsg, bootloader, etc. but instead update them through ota after flashing the stock firmware? Or will that cause bugs?
Thanks for the help and please don't throw hate at me, the last device that I hade with android had android 4.4 and a MediaTek chipset, then I switched to Windows Mobile till last year.

1) As long as you flash the same or newer stock firmware as the latest on your device, you should be okay.
As of writing, if you flash the June 2017, Sept 2017 or Dec 2017 stock firmwares (NPJS25.93-14-8, NPJS25.93-14-10 or NPJS25.93-14-13 respectively) then you shouldn't run into issues and be okay to take OTA updates provided you do a full flash. By a full flash, I mean flashing GPT, bootloader, system, OEM, DSP, modem and the erase steps. If you're flashing the NPJS25.93-14-8 firmware, flashing the same firmware should do nothing to your GPT, bootloader or modem, but is a good routine to ensure your device is clean.
As you're switching from RR to stock firmware, a data wipe/erase is recommended - you may be able to use Titanium Backup or another backup app to preserve your app data, then restore it after flashing the stock ROM (though ensure the backup is off your device). You will have to root your stock ROM to use Titanium Backup however.
The risks come when you flash stock firmware of an older patch level than the stock firmware currently on your device (custom ROMs do not matter in this regard) - strictly speaking, it's not the act of downgrading but attempting to take OTA updates whilst downgraded that causes hard bricks. In most cases, if not all, I've noted that a mismatch of the bootloader patch level and the system patch level are what cause issues for most users. You cannot downgrade bootloaders, so downgrading leads to the following situation:
Say you're on the June 2017 firmware:
June 2017 bootloader, June 2017 system (or RR).
You downgrade to Marshmallow or an earlier build of Nougat (say in this case Dec 2016 Nougat firmware):
June 2017 bootloader (bootloader will block downgrades with a security downgrade error), December 2016 firmware.
You try to take an OTA update. However, OTA updates are only designed for updating, and appear to assume (from looking at the script) your system patch level is the same as your bootloader. If you did not downgrade, this assumption would hold. However, as you've downgraded, you'll get this:
March/June 2017 bootloader *, March 2017 system.
Due to the OTA having authorisation to flash to your bootloader without prior checks, the older OTA corrupts your newer bootloader (as denoted by the *), leading to a hard brick. We do have a blankflash at the moment to help with this, though the easiest way to avoid this situation is to only flash firmware of the same or newer build that what is on your device. Motorola does not support downgrading and assumes the user takes responsibility for downgrading.
2)In theory yes. However, if TWRP was allowed to make modifications before you took the backup, the subsequent OTA might fail as your system partition would be detected as not read-only. Furthermore, you'd need a stock logo.bin, so if you've flashed a logo.bin to hide the bootloader unlocked warning, you'd have to pull that from the NPJS25.93-14-8 stock ROM. TWRP to my knowledge does not back that up.
3)As long as you take your time, and have not downgraded/hard bricked in the past, you should be okay. Ensure you back up as much data with Titanium Backup as previously mentioned, and ensure that you do a full flash, so your GPT, bootloader and system are at the same patch level. As mentioned previously, having your device on the same patch level should mean you have fewer issues with OTAs and stability.
4)I'm not sure what you mean by the June patch, do you mean the June OTA update, or do you mean the June stock ROM?

1) As long as you flash the same or newer stock firmware as the latest on your device, you should be okay.
As of writing, if you flash the June 2017, Sept 2017 or Dec 2017 stock firmwares (NPJS25.93-14-8, NPJS25.93-14-10 or NPJS25.93-14-13 respectively) then you shouldn't run into issues and be okay to take OTA updates provided you do a full flash. By a full flash, I mean flashing GPT, bootloader, system, OEM, DSP, modem and the erase steps. If you're flashing the NPJS25.93-14-8 firmware, flashing the same firmware should do nothing to your GPT, bootloader or modem, but is a good routine to ensure your device is clean.
As you're switching from RR to stock firmware, a data wipe/erase is recommended - you may be able to use Titanium Backup or another backup app to preserve your app data, then restore it after flashing the stock ROM (though ensure the backup is off your device). You will have to root your stock ROM to use Titanium Backup however.

Thanks for taking your time and answering my silly questions. 4) I mean the June stock ROM. And I've forgotten...
5) If you relock the bootloader, will you be able to unlock it again? How exactly does this work? The device gets another ID that you use again on the Moto site? Or you unlock it with the key that you used the first time you unlocked?
6) I have seen people that flashed the stock firmware through fastboot without relocking the bootloader and the software status shown in bootloader mode changed from "Official" (like mine) to "Modified" and the phone would show "Your device has failed verification and may not boot propertly." instead of the one with the unlocked bootloader. Just like here: https://www.youtube.com/watch?v=4OQQn105Bp8 . Though I have seen that some of these packages on xda are "Signed by Moto". So the problem does not occur when flashing those images?

Not true, that Modified status comes when you try to modify stock ROM, for various meaning, say installing mods in system (not in case of systemless), or if you try to remove/add apps to system/oem, when you change something in stock ROM, then you will get modified status. (Modification in custom ROM will not change it, only stock ROM does.)
So if you have official status right now, you don't need to worry about it.
Otherwise, to remove modified status,
You need to take OTA, (which can be dangerous as echo92 told you above.),
Bootloader relocking is not necessary to remove Modified, you can still take OTA and it will work..
> Flash June's patch (if you are 100% sure about current firmware)
> take OTA of September
Taking OTA makes it again official. (There was no update for bootloader in September patch, if not official again, December will make it..)

Ok then, since I'm 100% sure that I was on NPJS5.93-14-8 I'll flash that firmware, but where exactly do I find the one that I need? Doesn't the region matter? I'm on XT1642, in Europe, on the software channel reteu. So which one package do I use? I found 2 of them on AFH from tywinlannister7. And also, quite many people flashed the wrong modem and got into trouble, from what I've seen on xda. So any precautions I should take in that matter?
P.S. I don't want to flash the December patch since it updates the bootloader and there is no blankflash for that version yet... Also can't find the September one.

One by tywinlennister7, it is fine and confirmed working on different retails, (retin, retus, retla, many others.)
I have seen modem and other critical problems when one flashes old firmware (marshmallow roms), those all problems happened when old (MM) firmware is flashed.
You can take backup of all partitions by TWRP (fsg, data, system, boot, firmware, all options in shreps twrp), this all things can be helpful in case if something wrong happens, internal memory will be wiped so move them to external... Then flash....
About December, it's your wish to update or not.
If you are worried about blank-flash, then let me remind you again, you will need blank-flash only if you downgrade and take OTA. When you update to December's patch update, remove all older firmware on your computer and keep December's firmware zip only. If you need to flash stock, flash it, not other old..

List of Nougat firmware:
NPJS25.93-14-8 (June 2017) : https://androidfilehost.com/?fid=889764386195918175
This build appears to be targeted towards India, Brazil, EU and UK users, other territories may apply. This updates to NPJS25.93-14-10 (Sept 2017):
https://drive.google.com/file/d/0B9tngVBGIajVQkQtLUUxR2NOTnc/edit
NPJS25.93-14-13 is the December 2017 update from NPJS25.93-14-10: https://androidfilehost.com/?fid=745849072291698845
As ____Mdd has mentioned, the blankflash is only useful if you hard brick your device, and even then that usually only happens if you go flashing older firmware than what's on your device and then take an OTA update. If you don't downgrade, then you won't have a use for the blankflash normally.
If you want to be sure you're getting the right updates, you can flash the NPJS25.93-14-8 stock ROM, which should leave your device on the same patch level (if it was previously on NPJS25.93-14-8 and you're certain about that), then let the OTA updates download the correct patch. As your device firmware should all be on the same patch level, OTA updates should be okay. Bear in mind you may not receive the December 2017 OTA yet, as I've only seen it deployed to India/Mexico so far. It should be coming to EU soon if it's not arrived.

Ok, I was busy this week but I'm back with just a couple more questions:
Which partitions should I back up with the Partition Backup app and with TWRP? What format should I choose for the Partition Backup app?
Can I lock the bootloader after flashing and booting the stock ROM or do I have to do it while flashing?
I have restored my TWRP backup for NPJS5.93-14-8 and rooted it for the backup app. Is there any other helpful information about my device that I should share with you?
What should I install on my PC? I currently have mfastboot-v2 on my C:\ drive in the adb folder, should I install the Minimal ADB and Fastboot as I have seen people using it for the stock ROM flash? Also, do I need to install any drivers in particular?

1) If you want to make a backup, I would make a backup with the standard TWRP partitions selected (should be all of them but without cache). I've not used the Partition Backup app so cannot comment as to which formats to use, but standard formats for system and cache should be ext4, and data as f2fs.
2)Generally if you want to lock your bootloader, you should flash the stock ROM first, then boot to the stock ROM. In Settings > Developer Options, you will want to turn on OEM unlocking. Then, you can re-lock your bootloader with a full flash of all the commands. For more info and things to be aware of, have a look at this post: https://forum.xda-developers.com/showpost.php?p=74971791&postcount=497 Be aware that if you choose to lock your bootloader, you may not be able to use backups of data you made as TWRP and backup apps may require an unlocked bootloader. Anything you kept on internal storage should be transferable back to your device though.
Re-locking likely wipes data and internal storage, so ensure you back up and keep the back ups off your device - on your computer is the best location - until you are done. Also, be warned that any SD cards you have formatted and adopted as internal storage will be unreadable and need erasing, unless you retain the encryption key. So if you have an adopted SD card, back that up too.
3)I would install Minimal ADB and fastboot (v1.4.2 or newer) as most of the newer guides are based on fastboot rather than mfastboot (which is Motorola's version of fastboot, if I recall). You may wish to have the Motorola device drivers installed too - https://motorola-global-portal.custhelp.com/app/answers/prod_detail/a_id/79106/p/30,75,27,
4)That guide is quite old, plus only restores your device back to a state where OTA updates would be possible (i.e. flashing stock recovery, system, OEM). That guide you linked will not re-lock your bootloader.

So shreps' twrp can also backup the modems? I am on the 64-bit twrp from lannister7 (too lazy to check his name ) and it doesn't show the modems in "Backup", it only shows firmware, fsg, hw and ol the other stuff. And also, I have to flash the firmware twice if I want to lock the bootloader? I can imagine some really bad situations if you flash it with the OEM lock command included, some sh*t happens, you get an error and the device gets bricked whilst also being locked, and not being able to unlock it because of the "OEM Unlocking" option not being accessible, since the device would be bricked. So if I understand correctly, the OEM lock begin and OEM lock commands fully wipe the device, even the system, causing the need to flash everything again? Or the OEM lock commands require you to flash the stock ROM again because of safety issues?

Don't think shrep's TWRP backs up the modem, only the FSG partition (which appears to be half of the modem/baseband function). Modems are provided in the stock firmware anyhow.
Yes, you have to flash the firmware first (without OEM locking commands), then enable OEM unlocking in Settings>Developer Options, as I mentioned in the other post I wrote. Else, you may not be able to re-lock your bootloader. With OEM unlocking enabled, if a flash failed, you may still be able to unlock your bootloader and flash a custom ROM. Hence, this way gives you a way out, as you have OEM unlocking enabled, hence I recommending that you flash twice. After enabling OEM unlocking, then you flash fully with the OEM locking commands included.
Again, this is why I always say have plenty of time and do not rush this process, as this is critical to your device properly functioning, and to read up as much as you can on the pros and cons of the process.
The two OEM lock begin commands at the beginning of the locking command list will erase your device. Entering the first of those commands will prompt you and alert you to the fact your device is going to be erased. It only erases your data and likely your internal storage/cache, it should not erase any other partitions as they are usually not user modifiable.
If you are certain that your device is fully stock and at the same patch level, then you can use the OEM lock begin commands and OEM lock commands to lock your bootloader. However, if any of your device firmwares is not on the same patch level as your bootloader, you will likely have a boot failure as the firmware fails the bootloader verification checks (as the bootloader expects only firmware of the same patch level). Hence, I strongly recommend to re-flash the firmware to ensure you have clean stock firmware with matching patch levels.
Again, this process of re-locking your bootloader will mean no TWRP (no backups) or root or Titanium Backup.

Let me clarify my recent post of backup of modem,
All issue i have seen related to corrupted modems and HW partition are happened when one tried to flash older firmwares, those are marshmallow firmwares..
Till then, i have never seen any modem or corrupted hw partition while flashing latest firmwares..
Just make sure your downloaded firmware is latest or same as you have right now..

As ____Mdd has mentioned, backups of modem is only required if you've flashed the wrong firmware at some point (due to the different variants of stock firmware). You've given us no indication of that.
modemst1 and modemst2 are, as I understand it, caches and temporary storage of details that are normally wiped during a stock ROM flash, and are then re-filled when the device reboots. FSG is different to modemst1 and modemst2 I think, being one part of the modem/baseband firmware.
As we've both mentioned, modem and FSG are both provided by the stock ROM (as NON-HLOS.bin and fsg.mbn).

I have made it! I've flashed the stock rom without any problem or error!
I want to thank you all because I wouldn't have been able to flash this without your help! I have also locked the bootloader, then I updated to September update and, shortly afterwards, to December update. Now, if I will ever flash custom ROMs again (which has a high probability) I will know how to restore to the stock ROM. So thanks, and I will leave the thread open if anyone will have the need of assistance with this process, or maybe I will have other questions in the future! So, for the third time, thanks for your valuable help guys!

Unlocked bootloader and OTA updates

Will i recive OTA update if i unlock the bootloader?

Yes. Just unlocking the bootloader still allows everything to work normally, though you can't install otas if you mounted or modified /system and /oem partitions, or have twrp recovery.
Otherwise your phone should still function as if it weren't unlocked.

In addition to the above reply - if you do modify your system and want to flash back to stock firmware, please check if you can download the correct firmware for your device. I see from your history you have a retEU device, so the latest series of firmwares would be the NPNS25.137-93 series (with NPNS25.137-93-10 being the April 2018 security patch). I'd suggest checking to see if there is a stock ROM matching your current build before you unlock the bootloader (either at https://mirrors.lolinet.com/firmware/moto/potter/official/RETAIL/ or https://firmware.center/firmware/Motorola/Moto G5 Plus/Stock/ or https://androidfilehost.com/?a=show&w=files&flid=171014 ) though it seems the latest firmware that's been leaked is NPNS25.137-93-4 (the Jan 2018 security patch build). Just as a headsup, firmware.center has a cryptominer that could keep your CPU at 100 % if you have their page open.
If you download and flash the NPNS25.137-92-10 firmware, which is the April 2018 security patch for Brazil/India devices, you may be able to re-lock your bootloader and get back to full stock, but you may not be able to receive OTA updates (as the NPNS25.137-92 series of updates do not appear to be deployed to the retEU channel), so be careful which firmware you flash.
You can still unlock your bootloader without having the latest firmware to hand, but until the firmware matching your stock firmware before you unlocked or newer is available, you may not be able to re-lock your device. You may be able to flash older stock firmware for EU devices, but please do not use OTA updates if you flash older stock firmware, else you may hard brick your device.
Good luck whichever way you decide.

Yes. Just unlocking the bootloader still allows everything to work normally, though you can't install otas if you mounted or modified /system and /oem partitions, or have twrp recovery.
Otherwise, your phone should still function as if it weren't unlocked.

Yes the Same thing Happened
I had TWRP recovery and I installed the Security Patch
my Phone Stuck at TWRP
but it has One solution
First, take the data backup of all in twrp at your sd card
now install any custom Rom
Reboot your device and check the rom is working or not
do reboot and go back to your Twrp and Restore the backup
I tested it and It worked perfectly

In addition to the above reply - if you do modify your system and want to flash back to stock firmware, please check if you can download the correct firmware for your device. I see from your history you have a retEU device, so the latest series of firmwares would be the NPNS25.137-93 series (with NPNS25.137-93-10 being the April 2018 security patch). I'd suggest checking to see if there is a stock ROM matching your current build before you unlock the bootloader (either at https://mirrors.lolinet.com/firmware/moto/potter/official/RETAIL/ or https://firmware.center/firmware/Motorola/Moto G5 Plus/Stock/ or https://androidfilehost.com/?a=show&w=files&flid=171014 ) though it seems the latest firmware that's been leaked is NPNS25.137-93-4 (the Jan 2018 security patch build). Just as a headsup, firmware.center has a cryptominer that could keep your CPU at 100 % if you have their page open.
If you download and flash the NPNS25.137-92-10 firmware, which is the April 2018 security patch for Brazil/India devices, you may be able to re-lock your bootloader and get back to full stock, but you may not be able to receive OTA updates (as the NPNS25.137-92 series of updates do not appear to be deployed to the retEU channel), so be careful which firmware you flash.

I would unlock the bootloader just to try to fix the camera (then edit the system files), not for flash twrp / custom rom

Just unlocking the BL wouldn't be enough to edit system files. You'll need root privileges to do so and for that you will have to flash/boot TWRP to install a root app like magisk.
So all the useful information @echo92 posted above is significant for you.

Is there a way to take TWRP off or disable to still grab the security patches? Or is clean install/backup (like Rutambh mentioned) the only option? The reason I ask I needed TWRP to install camera mod, so it would be nice to still get those OTA's. I tried to just fastboot boot TWRP but it would just hang at it's logo. Flash was only option.

If anything in /system or /oem is tampered like installing a camera mod (or just mounting system r/w) the only way to receive future OTA updates is flashing your current ROM incl. stock recovery via fastboot.
