After flashing phone changed from G4 Plus to G4

I've flashed a stock firmware everyone else flashed. But after flashing, my phone's fingerprint and networks are not working.
In the settings, the baseband is also not "ATHENE_INDIA_DSDS_CUST". It's "DFLT_FSG".
Please help me.

You flashed the wrong one obviously. Which file did u flash?

That's the correct one. Only your baseband is different? Rest all works. In that case just flash fsg.bin and NON-HLOS.bin and wipe modem1 and modem2.

Tried flashing it. No success. Also the fiingerprint reader is also missing.

Even i have the same issue...FP sensor is not recognised during initial setup and also the setting is missing in the settings menu.
Flash the Indian modems doesn't work. Dailing *#06# shows only one IMEI number.Sim card is detected but always stays on No service mode....attempting to search for networks from setting results in an error.Service centre didn't accept my phone saying theres only one IMEI number and the bootloader is unlocked.Any help would be appreciated as we have no where to go.

Glad that someone acknowledge the issue. There is one more guy here at xda roaming with the same problem. I've tried almost every method possible. Still no luck. But for luck, my service center guy offered a free board replacement for the problem. If xda guys didn help, I would send it for replacement. Mine is also bootloader unlocked and software status modified, but he is okey to offer a replacement.

Which city ?I think you should go for the replacement and then update it via OTA when you get a notification.

Any Solutions Yet ?
Has anyone found any solutions yet !?
It is surely a Software issue
Service Center people are asking Rs.6500/- to replace the motherboard
Can't even relock the bootloader as i flashed the Nougat OTA and thus i can't downgrade the bootloader and lock it either !!
Please Help !

A few things:
1) As long as you are fully updated to the latest stock ROM, OTA updates should not be a problem. OTA updates are usually a problem if you have downgraded your device (like in your case downgrading to Dec 2016 firmware) or not having the full stock ROM, including the bootloader of the same patch level, (i.e. having mixed firmware) flashed to your device. If you really want to, you can use the latest stock ROM to re-lock your bootloader, and providing it's the correct stock ROM for your region/device, you should receive and be able to flash OTA updates without problem (as a locked bootloader will enforce you having firmware matching the bootloader update level).
2)I'm not sure how a minimal ADB/fastboot image is 900+ MB. Unless that mediafire link is pointing to the Android SDK which includes the ADB and fastboot programs, the minimal ADB/fastboot is about 1 MB https://forum.xda-developers.com/showthread.php?t=2317790
3)Unfortunately, repairing IMEI and loss of fingerprint sensor is not as straightforward as flashing the stock ROM. You may require the hw, fsg and modem images.

Well
1. if you have unlocked bootloader, you can not re-lock. i think this is the brick's reason. i had installed yes old bootloader file with december 2016 security patch, then came ota update to april 2018 security patch and phone has bricked, as from marshmallow to nougat update while bootloader was unlocked. but i do not know reason exactly, because first time i did stock marshmallow 6.0 rom, then came ota update everything works fine new security patch of 6.0, after that came nougat ota update and phone was bricked
2. yes there is difference between .rar and folder. just extract it
3. if it is hardware issue, rom can not change anything yes

1)You can re-lock your device with the April 2018 stock firmware https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138. You need a stock firmware image as new or newer than your bootloader - we've seen many examples on this stock ROM thread of users re-locking their bootloaders.
The likely reason that you hard bricked is that you did not actually downgrade your bootloader when you flashed the Marshmallow stock ROM. Hence, you still had the Nougat bootloader on your device, which got corrupted when you used the old MM to Nougat OTA.
To re-lock your device, you must use the newest appropriate firmware for your device. Do not flash old stock firmware (including MM) and do not mix your firmwares (do not flash old bootloader files with new firmware). Of course, re-locking your bootloader will not restore your warranty and the process will erase your device, so up to you.

If you have a look and read of the stock ROM initial post https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138 in that guide you'll see flashing commands that should let you re-lock your bootloader.
Also, if you want to re-lock your bootloader, check that you have OEM unlocking enabled in Settings>Developer Options (the same toggle you turned on when you unlocked the bootloader in the first place).
So the summary is:
1)Turn on OEM unlocking in Settings>Developer Options.
2)Boot your device to bootloader
3)Fully flash the April 2018 stock ROM (all files must be from the April 2018 stock ROM, no exceptions) as per the flashing commands in the guide, including all the OEM lock commands. This should wipe your device, re-lock your bootloader and let you boot with stock files. Attempting to mix files will cause your lock to fail or your device to not boot, as the firmware you flashed is now being checked by your bootloader to verify it's all from the same firmware.

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.

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.

Help regarding flashing stock and ota

Hello!
I've the Indian variant of the Moto G5 Plus (XT1686), software channel: Retin. I have unlocked the device and flashed a custom ROM. I want to return to stock now but I have a few questions.
1) Where can I get the latest factory image for my XT1686?
2) Which one should I flash on my device amongst AMZ, RETLA & RETAIL?
3) I was on the November security patch before I unlocked and rooted. Should I flash stock, will my device continue receiving ota updates that are released for India?
4) If I flash the firmware that you guys will link me to here, will it hard brick my device when I try for ota update in the future? I read somewhere about mismatch in the partition table will lead to 9008/ some error and device won't go in bootloader mode and that you'll need blankfiles to revive your device and stuff.
Please tell me what to do to return to my complete stock image and to continue receiving ota updates safely on my XT1686, RETIN Software Channel?

1) To the best of my knowledge, this NPN25.137-92, Nov 2017 stock Motorola firmware, is the latest for retIN (retail India) devices, amongst other regions. https://forum.xda-developers.com/g5-plus/how-to/moto-g5-plus-patch-november-npn25-137-92-t3718976 It's been received by OTA to users, indicating it's been formally deployed in India and other regions too. Please verify this before flashing
Flash using the flashing instructions provided in this post: https://forum.xda-developers.com/g5-plus/how-to/solution-to-flash-stock-romfactory-t3691396 but using the above NPN25.137-92 ROM - the flashing instructions should apply to this ROM.
2)As you're on retail India, you want retail stock ROMs. AMZ are only for Amazon Prime devices (bootloader locked to Amazon, adverts on the lockscreen) and whilst you could flash retla (retail Latin America), it may cause problems for your device later down the line.
3)Provided you flash the correct stock firmware for your region, you should continue to receive OTA updates.
4)As this should be the same firmware as you had previously, you should not hard brick when receiving OTA updates in the future. Users appeared to commonly hard brick when they attempted to flash stock Motorola firmware older than the stock firmware they had (custom ROMs don't appear to matter here), then attempted to use OTA updates. You cannot downgrade bootloaders, thus you have a mismatched bootloader and system - your new bootloader and your downgraded system - so using an OTA update would flash older bootloader files. As OTA updates do not have the same checks as fastboot for bootloaders, that would corrupt your newer bootloader and hard brick your device. The OTA updates don't appear designed to consider downgraded devices, i.e. newer bootloaders but older stock systems, hence why Motorola likely warns you that whatever happens when unlocking the bootloader is the user's responsibility. If you were in that situation, then flashing fastboot ROMs would be the safest way to update.
However, as you're being conscientious enough to flash the same or latest firmware, then this should not occur. To summarise, hard bricks only appear to occur when downgrading/cross flashing stock firmware and then taking OTA updates when you previously had newer/different stock firmware on your device.
If you want to be truly sure this is the right firmware to revert back to stock to, then I would like to see your getvar info before proceeding:
1)Boot your device to the bootloader, connect to your computer via USB.
2)In the ADB terminal, type 'fastboot getvar all' without quotes and press Enter.
3)Copy the output to a post here. This output contains device variables including what the last stock firmware was on your device, which will be helpful in verifying the correct firmware for you. You may wish to remove IMEI from the output before posting.

Guys i unlocked the bootloader of NPN 25.137-92 indian retin variant with nov 1 patch. I unlocked the bootloader and rooted the phone with SU, only problem is that cam stops working. Then i installed Elemental X kernel 2.02 as a workround to get the cam working which went ok . But i want to go back to the stock kernel, i dont want to flash whole rom . Is their a way i get info or download link for the stock kernel, please reply. Is it possible that i can just flash the kernel.

Answered on your post, please check

Custom ROMs and future updates. What do I have to bear in mind?

So, we all know Motorola will eventually (aka never) release Oreo for the G5 Plus.
I am way too anxious so I am going to flash a Custom ROM until they deliver it. However I am quite afraid about something.
I plan to use Lineage 15.1 until Oreo comes out for the G5 Plus. However, I am kind of afraid that I may screw things up when the OTA comes out.
I have recently hard bricked my Moto G 2014 because of OTAs and Bootloader.
So, Oreo releases...
Will it be fine to install the OTA (through normal System Update check) having the latest Stock ROM Firmware for my region installed? (I would erase Lineage 15 and use fastboot to flash Stock again)
Or will I instead need to wait for someone to post the system images and flash it through fastboot instead? (I assume I would need to install the OTA through normal methods because of bootloader changes but still...)

I just don't want this: https://forum.xda-developers.com/g5-plus/help/moto-g5-plus-hard-bricked-t3694119
To happen.

You won't get system updates when you are on a custom ROM like Lineage OS or any other custom ROM. The only system updates you might get are ROM updates if the ROM maintainer has that feature built in.
If official Oreo comes out and you are on the correct stock firmware for your model and region, everything should work fine.

Before flashing custom roms you should backup your efs partition using twrp else you could lose your imei(recoverable) / volte(not recoverable till now) when flashing fastboot firmwire.
You need to flash fastboot firmwire to receive oreo ota.

If you want to avoid hard bricking, then you must flash the same stock ROM or newer onto your device when you revert back to stock firmware.
I imagine your Moto G 2014 got bricked when you took an OTA update? That could have occurred if firmware older than what was present on your device was flashed (bootloaders cannot be downgraded), and like in that thread you linked, attempting to use OTA updates would corrupt your newer bootloader with the older OTA patches, leading to a hard brick.
As mentioned above, if you revert to the correct build for your region and matching your current build at least, you should be okay to receive OTA updates (should also include up to Oreo). Alternatively, you could wait for the Oreo fastboot ROM to be safe, or the Oreo TWRP flashable for a near stock ROM experience (since TWRP flashables shouldn't care about your bootloader or GPT partitions, do it'd be difficult to brick your device. However, TWRP flashable stock ROMs aren't OTA compatible).
Before you unlock your bootloader and flash TWRP/custom ROMs, make a note of your current build version and see if you can find a stock ROM leaked of that build, so you can be sure that you're reverting to the right build for your device.
Just do not flash older stock Motorola firmware to your device or if you do, do not use OTA updates.

Yeah, I did some research and now I understand what happened. Thanks for the comments.

[mini-GUIDE] BRICKED / DOWNGRADE / SAME / UPGRADE - also ALTERNATIVE to RSDlite

I am not responsible for your bricked phone or pigeon poo on your toupe. Do at your own risk.
Many thanks to @SupahCookie for idea and motivation!
INTENTIONALLY DOES --NOT-- LOCK BOOTLOADER!!!
Get factory images here:
https://forum.xda-developers.com/mo...ock-images-t3736767/post75236696#post75236696
THIS GUIDE IS FOR FACTORY/STOCK ROMs - NOT YOUR AVERAGE CUSTOM ROM which may not have bootloaders!!! (thanks!!!!! @echo92 )
FIX:
IF YOU ARE ABLE TO GET TO FASTBOOT THIS SHOULD WORK.
IF YOU HAVE 8.x bootloaders AND ARE DOWNGRADING TO 7, use "Alternative to RSDlite" below.
1 boot to win - 7 or 10 works fine.
2 boot phone to fastboot, and connect phone to computer.
3 start RSDlite
pick a ROM. I believe I used a 7.1.1 rom
3Nov9-ADDISON_NPNS26.118-22-2-8_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip
RSDlite installed it and fixed the problem.
- -
I was then able to use RSDlite to install @rafikowy 's signed 8.0 . - going up from 7 to 8.
- -
- -
If you are on 8.x bootloaders and want to go to 7.x bootloaders, use this (RSDlite throws an error and stops):
ALTERNATIVE TO RSDlite:
1 I used 7zip to extract that 7.1.1 zip (or any ROM zip) into a folder x,
2 add all the adb and fastboot junk to folder x,
3 add the attached file (rename it to flash.bat) to folder x.
4 boot phone to fastboot and connect to computer.
5 click on flash.bat - it throws a lot of "slot" errors but works just fine.
6 reboot your phone if it hasn't already and go through the 7.x install stuffs.
7 you will not show an IMEI if you are coming from an 8.x bootloader. However, it IS there.
NOTE: you may need to add a line to the flash.bat if there are more/less sparsechunk's in your FACTORY/STOCK ROM...
THIS IS NOT FOR CUSTOM ROMs!!!!!!!
EDIT: 3-8-19: I just did this myself to go back very briefly to 7.1 - be sure you don't flash TWRP to it if your going to take OTAs - it will brick it. boot to TWRP if you need TWRP briefly: fastboot boot twrpimg.img
----------
If you can boot to fastboot screen, you can do anything.
Never OTA a ROM if you have modified recovery (TWRP, etc) or if magisk is present.

I changed the attached file to add pause and reboot and exit to make it slightly more automated.

I have successfully used this many times going back and forth. If you can boot to fastboot screen, you can save your phone and flash anything you want.

You may wish to advise users that if they downgrade to Nougat not to use Nougat OTA updates. The reason being that a downgraded stock Oreo device may still have the Oreo bootloader on it. Thus, attempting to use Nougat OTA updates may hard brick their device (as the bootloader is likely corrupted, meaning no fastboot).
Users could either use the Feb 2018 NPN26.118-22-2-17 firmware from your link https://mirrors.lolinet.com/firmware/moto/addison/official/RETAIL/ as that was the last Nougat firmware (and thus no Nougat OTA updates) or avoid using OTA updates whilst downgraded.

Interesting. I used the above GUIDE to go up and down a number of times on my phone (about 20 total) , installing and running on both 7 and 8, and then went down to a Nov 7.1.1 and let it ota all the way up to 8.0 and that is what I am using now. I found that when i used a factory zip, and the above procedure, it corrected the bootloaders to the appropriate version that i was flashing - either RSDlite or the more manual path which ignores the errors worked for me.
Using the above procedure , you get the correct bootloaders, which are in the zip.
Please correct me if i am wrong!

That's intriguing - we saw previously on Z Play that users downgrading their stock firmware (e.g. https://forum.xda-developers.com/moto-z-play/help/hard-brick-moto-z-play-patch-abril-t3782927 )and then using OTA updates hard bricked their device (hence the number of users asking for a blankflash, as fastboot no longer works). I don't know if these users hard bricked by downgrading their firmware too far and then flashed an OTA radically different to their previous firmware, or whether it's a risk that's taken by any downgrading of firmware.
When you used fastboot, did you see any 'security downgrade errors' when you flashed the bootloader, and is your bootloader version now C180, as you've flashed the Oreo OTA?

YES - that's why I wrote these 3 guides - before, it was quite possible to wind up with a bootloader mix - esp depending on the zip you use! - factory/stock only!!!
I added a line to the guide saying that it is only intended to be used for the factory/stock zips as these have (I believe) the bootloaders appropriate to the ROM.
Many thanks for pursuing this! - I wonder if we'll have to exclude certain ROMs that are in the factory lists?????

If you have TWRP (or I assume any custom recovery) present when you try to ota, it can download just fine and then reboot to the update. I had TWRP and wound up in a situation where my phone would only boot to twrp no matter what I flashed or restored. I booted phone to fastboot, RSDlite'ed that 11-09-17 factory zip and all was well. In that particular case I did not fully install 7.x but immediately RSDlite'ed rafikowy's 8.0 signed stock and went on with my testing. Since then I always boot to TWRP rather than intalling it and do my thing. (thanks @jceballos )

Sorry - since it throws a million errors I never look at it if it works.
The particular build I am on at the moment - is BL: C1.82
This one started from that Nov '17 build and ota'ed all the way to 8.0 Apr.
I root and unroot as needed per rafikowy's method but using a boot to TWRP - never an install TWRP.
I'll put up a new guide ref ota and recovery and brick.

1) If you have TWRP, then using an OTA will fail - as you've not got stock recovery (and likely other modifications, including possibly a system partition set to read-write status). As you noted, having TWRP seems to cause a bootloop when rebooting - I'm not sure if the OTA sets a boot flag to stay in recovery until the update is completed. For the G4/Plus, there's a possible solution by wiping the misc partition but I don't know if there's a similar partition for Z Play devices: https://forum.xda-developers.com/moto-g4/help/troubleshooting-twrp-boot-loop-ota-t3714325
The only other solution I've seen is a clean flash of the stock ROM to get your device booting properly.
Booting to TWRP rather than flashing would mean your stock recovery is still present on your device. The only downside is if you need to make modifications, you'd need your computer to boot to TWRP.
2)BL C1.82 seems to be the bootloader provided by the Oreo April 2018 security patch update, so your device looks to be on the right bootloader. It's still curious that the Nov 2017 firmware worked whereas countless other 'factory' stock ROMs caused hard bricks when downgraded to and then OTA updates were installed.
As you mentioned, custom ROMs don't have bootloaders and thus don't care about your bootloader version usually (though I've seen some ROMs require a certain bootloader). However, stock ROMs and stock OTA updates do have bootloaders, which is why downgrading can be risky.

Downgrading is a piece of cake if you don't use RSDlite - it throws an error and stops. Using the bat file it can happily throw all the errors it wants and all I care is at the end I have what I want.
It does indeed change the entire environment when you bat file the zip contents. You can bat file to get from 8 to 7 and then use RSDlite to flash a different 7 OR 8 zip file. There is no resulting difference in whether you RSDlite it or bat file it - the bat file simply comes from the .xml file that is within the zip. There is very little or no difference between that among addison factory/stock zips. Other zips are different (custom ROMs.)
Grab any factory/stock zip for addison and expand it and you will see modems, bootloaders, indeed absolutely everything you would find on that phone if you went to a store and bought it. SupahCookie simply added a couple lock command lines because it was intended for folks who somehow thought that if phone was locked they could take it back to the store and get their money back. Or some such. I found that ATT folk didn't care if you were on CM or whatever if you just needed to swap SIMs or whatever.
I DON'T want to lock the phone as it prevents me from modifying forever. Oh yeah that reminds me I was going to post the obligatory guide (again) about how to flash a white boot logo so you don't get that message - it's still there LOL but since the font is in white, you can't see it.

I have a Moto Z2 Play and used this to get out of a rather sticky situation.. My IEMI shows 0 now and I'm curious if there's a way to fix this? Also, You say you've done OTA updates? My phone is telling my I have some, is it safe to try?

Thanks for feedback and great on success.
IMEI will show zero if using oreo, It will show again if using N. Remember that if you go from O to N you need to use the "Alternative to RSD" as RSD will simply throw an error and stop.
If you have TWRP and/or Magisk you must get rid of them before ota - if twrp present you will soft brick and have to do alternative again - flash a stock recovery. Simply uninstalling/flash magisk will probably not be enough - it will likely d/l but error part way through update. If you are sitting on rafikowy's stock oreo, and haven't modified it, you should be fine. I know Apr and June are out there. I flashed his stock 8.0 and took June fine. Z2 should be no different though of course I can't guarantee it
If you have success, let us know what you have done so others looking in will know. Thanks!

I actually flashed to this: ALBUS_C_7.1.1_NPS26.118-24_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip Which is a 7.1.1 variant and it is showing 0 when I check settings and when I dial *#06#. However upon connecting to the computer and running mfastboot getvar imei it returned a value. I only did the steps above which would mean I don't have TWRP or Magisk (when I fastboot and click recovery I get "no command")
****** Additional information *********
XT1710-01 Duel Sim Variant
I started your steps, only being able to access fastboot. The device would throw an error (I don't recall exactly but it ended up showing me them in the bootloader logs) whenever I tried to start it, or go to recovery. #DefinitelyThoughtItWasDead

It had 7.1.1 stock. I rooted it, and then flashed Resurrection Remix (which was yes 8.1 I believe) and the upgraded bootloader. I then found out my service wouldn't work with that.. so I attempted to flash back to stock which gave me a flurry of issues.. eventually getting to nothing but fastboot working. Flashed back to working with your guide to 7.1.1
If it helps in in fastboot it tells me BL: C0.CD

Custom ROMs won't usually update the bootloader (even if they are newer) as stock ROMs typically only have the bootloader firmware.
You could look into flashing the stock Oreo albus 8.0 ROM https://forum.xda-developers.com/z2-play/how-to/fastboot-rom-oreo-retail-via-fastboot-t3786153 or the 8.0 June 2018 firmware https://forum.xda-developers.com/z2-play/how-to/fastboot-rom-albusretail8-0-0opss27-76-t3822195 but please check that firmware has been released for your device variant.
I don't know if updating your baseband to stock Oreo formally may fix your IMEI issue.

"BL: C0.CD" even right after flashing that albus 7.1.1 using "alternative" above?
What happens if you flash one of the oreo roms from the links I gave you above?
Yeah, RR wouldn't change bootloaders... so you upgraded bootloaders independendently?- that could easily lead to a soft brick... -
I read RR on Z2 and it says nothing about bootloaders even though it says 8.1 based, so i wonder if it needs 7.x bootloaders? I did not read entire thread...
In a reverse, I would wonder if you put an 8 on there if you wouldn't see your IMEI. (On the Z if you flash 8 You won't see the IMEI until you return to 7.)(wondering if z2 is reversed)

Yes, right after flashing that is the BL that fastboot is showing me. I don't recall updating the bootloader so to speak, however RR did require an updated variant of twrp which I flashed 3.2.2 I believe to get (unsure if that would have changed the bootloader or not). I also tried flashing a stock Oreo (which you've stated stock Roms usually only have the bootloaders so maybe somewhere during this process I updated it?). I wish I had all the notes for what I did to give more precise information, but I'm in a position where I really need my phone so I kinda just panicked and started flashing things when my service wouldn't work.
I'm highly considering trying to run an OTA (though very afraid of bricking). - On a side note though, it wouldn't even tell me I had OTA's until I did the steps in the original post here (doing the different 7.1.1. and 8.0 flashes, it wouldn't ever tell me I had updates, and now it does).
*** Edit ***
Looks like I'm able to enter stock recovery, which makes me believe everything is stock at the moment.

If you flashed a stock O that would have changed bl to O, but doing the above with the stock 7.1.1 would have changed them back to N. No matter (other than academic) that you don't remember the path - flashing a stock anything reverts it to that point in time. However, IMEI may have been moved - don't know. It will likely show on EITHER 7.x or 8.x stock - just don't know which.
If you flash a stock 8.x from those links I gave you above, it should offer you ota, ASSUMING there are any at this point in time(Z has 2). Adding Magisk at any point seems to hose you for receiving any more ota's - don't understand why, even with magisk uninstall, so that would mean going back to the latest stock and losing what you have (which is why I try to take a TBPro and copy that backup to PC (because re-flashing 8.x stock will likely reset internal storage.).
yes, if you enter stock recovery, you are likely at stock, though you could reflash the latest 7 or 8 stock to be sure, depending on which you want to use as base. Since 8 is having security fixes released, I choose 8 and will likely have no more interest (no time!) in 7.

So, ran the OTA and it was fine running the update and staying on N. I also downloaded the OTA for Oreo, when trying to update the recovery error'd out. It looked like the error said "Error in modem unexpected results" or something similar.

did it offer to let you d/l it again? you could try that.
However, there exist O stock zips in those links I gave you so you could just flash the latest...
