Upgrading from Oreo stock rooted to Pie stock - LG G6 Questions and Answers

I'm rooted with unlocked bootloaders. I've oreo stock and I'd like to upgrade to pie stock through an official firmware (released by LG). I wonder which is the correct sequence for not breaking the smartphone: do I have to lock the bootloaders again ? And what about the twrp now installed ? And what should I do to be rooted again ?
To be pointed to a guide would be fantastic!!!

I have a Zenfone 2 LAser ZE550KL with locked bootloader. Android 5.0 version installed. Not yet upgraded to Marshmallow.
Can we use that official unlock app to unlock bootloader and then upgrade to marshmallow through the OTA?
Is that possible?

Upgrading to LOS from 6.0 Stock?

Hello, will this be possible? I can't upgrade to the stock Nougat firmware because I have unlocked my bootloader which is causing me problems, I can't upgrade with the instructions found here in XDA, and I'm running the latest official Marshmallow build. Thanks!

I had no issues. I'd prefer an earlier Marshmallow build though. Doze mode in Nougat is so messed up that battery life went down a lot!!

Can I safely flash back to stock Marshmallow?

My Moto G4 came with Marshmallow installed and I performed an OTA update to Nougat. I then unlocked my bootloader and flashed some custom Nougat ROMs (7.1.2, so newer than the newest official available version). Now I want to get back to stock Nougat so I can relock the bootloader and all that jazz.
As far as I can tell, only Marshmallow firmware images are available so can I safely flash that (I'm thinking "ATHENE_MPJ24.139-23.4_cid50_subsidy-DEFAULT_CFC.zip") and then OTA to Nougat from there or will that cause problems because I already (presumably) have the Nougat bootloader version? I don't want to brick my phone!
Note I'm using a retail United Kingdom XT1622 Moto G4.
Cheers all in advance,

Ah ha! Found this:

Got back to stock Marshmallow all OK
flashing back to marshmallow and being able to relock the bootloader after doing the ota wont really work. best bet is to try and find the stock nougat image and flash it.
