[HELP] OTA Updates

Hi my device Moto G4 plus XT1643 is :
Android version 7.0
Build Number : NPJ25.93-14
Security Patch : 1 December 2016
Rooted.
Can someone help me find all the OTA update captures after the December patch OTA.
Also a way to flash them without unrooting my phone, FlashFire almost never works for me , maybe some flashing with rsd?
I rooted my phone with this method and with ElementalX kernel : https://forum.xda-developers.com/moto-g4-plus/how-to/guide-how-root-nougat-moto-g4-plus-t3484672
Thank You in advance and apologies for my naivety.

You can't flash an original ota update with a custom kernel and recovery. You need stock recovery, otherwise it's not possible. Therefore you will loose root.
The easiest way is to flash the whole stock rom with June security patch and install ex kernel and twrp again.

That's it.

Download Nougat or Marsh from sammobile and flash t with Odin, more instructions on sammobile.
downgrade only possible with V2 firmware files, don't flash any firmware build before the january 2018 or you will brick your device .

I am new here i dont know what is V2 firmwarefile. Can you explain what is V2 firmware?? Thanks you for advise:fingers-crossed::fingers-crossed::fingers-crossed:
I mean the bootloader version that is written in the firmware name i.e in G935FXXU2DRAG, 2 is the bootloader version of the firmware after U letter and if you are already on version 2 bootloader, you cannot flash a firmware which has 1 in place of 2..

Ok Thanks you bro!!!!:fingers-crossed::good:
This is useful! I tried to downgrade from 8.0 to 7.0 and bricked my device, luckily I could restore the same version I had before... even SmartSwitch don't give a damn about my device anymore.
If you have bootloader version which says XXS2 then you can't downgrade to Marshmallow and initial Nougat firmwares released till December 2017.
However, if you never upgraded your bootloader to v2 (like me), then you can downgrade to even Marshmallow without any issues. Check my phone screenshot. I am running latest Oreo firmware on v1 bootloader without any issues.

Is it possible to downgrade from Oreo to Nougat after September security patch?

Is it possible to downgrade from Oreo to nougat after September security patch? Cause I can't install any .zip install via "apply update from sd card".
EDIT: I've found a way to downgrade after September security patch.

bootloader unlock Can You Receive Updates via Ota or No?

I am curious about these issues, my question is the following when I unlock my Bootloader I can do an update via OTA when it arrives on my device? Or is my phone going to have Hard Brick?
I want to give a Downgrande on my smartphone but it is still in stock without any modification. And through the tutorials I read ask for the unlock Bootloader. My intention is to only downgrade. A friend of mine gave the following idea: "unlock the bootloader to then downgrade and after it has been successfully done." I search how to lock the bootloader again using CMD to put a system with the bootloader locked and so in the future I will be able to receive updates via Ota. " Does This Worker Ideas In Practice?
This my Frist Post here If I make a mistake, tell me, we will not repeat.:fingers-crossed:
When it comes to being able to receive updates when bl is unlocked, that's a yes, it will work fine and won't affect your phone's functionality.
On the other hand downgrading is generally a bad idea. The problem is, when you update your phone your bootloader also gets an update. All parts of the OS except for the bootloader can be downgraded to a previous version, and if you do that, the downgraded OS can function normally on the newer bootloader.
Now comes the tricky part. If you try to do an OTA on a downgraded OS with a new bootloader, the OTA will treat the bootloader as if it were the old one, and will overwrite parts of it that it shouldn't, which will corrupt it. And there you have a pricey paperweight.
The only way of updating a downgraded device is to flash it clean with a newer version (or the version same as the bootloader).
Now what is the reason you'd want to downgrade?

My bootloader is unlocked.
I wanted to upgrade to the latest firmware and because I was rooted I flashed the firmware I was on at that moment (no down - or upgrade) again and after that I was able to apply and install every single OTA up to the latest. I could have flashed the latest Oreo firmware directly too but I wanted to test this way and to update by flashing latest firmware would have been possible after that too.
So updating via OTA with an unlocked bootloader was no problem for me.
In the end you get the unlock code from Motorola itself and it would be kind of strange if they won't deliver updates anymore for a feature they provide for their devices.

I am planning on to unlock bootloader only will I continue recieving official updates from Samsung and able to install them (not flashing that, OTA ones). I am not going to install custom recovery or kernel or even custom rom. Will it work that way?
