I have unlocked my bootloader, installed a TWRP, and flashed a custom ROM. Everything is working fine, but I just want to know how to return to stock if I wanted to. Is it just as simple as flashing the latest OTA? Do I have to re-lock my bootloader?
Thanks!
You can easily return firmware and/or recovery to stock by flashing, but currently there is no way to relock the bootloader.

I'm sort of a noob when it comes to this stuff. I usually just follow guides to get what I'm looking for.
So would I just download the latest OTA and flash that? Can someone share some simple instructions on how this is done?
Thanks!
When you want to flash back to stock from custom, are the steps the following?
1)Download stock rom from asus
2)Format phone
3)Flash stock ROM from custom recovery?
The reason I ask is because there is a guide that says you need to edit the stock rom when flashing from custom rom/recovery.. Link to his guide here: GUIDE FOR FULL ROM

For warranty purposes, i need to do these. Currently, my FLO's bootloader is unlocked, rooted and has custom kernel and recovery. but it is still in Stock JSS15R Rom. how will i unroot, flash stock kernel and relock without downloading stock roms? is that possible? because the method i only see here is to flash stock rom or use nexus toolkit to unroot. but i think when i use the toolkit it downloads the stock rom again right? thanks in advance!

^thanks for this! i'll try this later..
Hello all developers, I have a noob question, please guide. I have ZenFone 2 running on stock android 5.0 and it is rooted. Now I have to flash custom roms and mods but also want to update stock Rom to android 6.0 whenever ASUS provide updates. So I have a simple idea as below -
1) Install flashify app.
2) Take backup of stock recovery.
3) Flash CWM.
4) Take nandroid backup.
5) Now I can flash custom roms.
6) When ASUS provide updates, flash nandroid backup.
7) Flash stock recovery through Flashify.
8) Full unroot from supersu.
Thus my phone will be fully stock and I can update stock Rom to android 6.0 .
Will this trick work; please tell. I am eagerly waiting for your replies.
[emoji4] Thank you [emoji4]
you have to unlock bootloader if you want to flash custom rom !!!
if you unlock bootloader with official tools. you cant receive any update from asus with OTA. but you can flash full stock rom with twrp via sideload or edit stock rom zip then install with twrp.
somebody can unlock bootloader without official tools (i dont try) and they can update OTA

Thank you very much for the information. Btw, can I make changes to stock Rom without unlocking bootloader and revert back to fully stock phone when OTA comes with the above method ?

Hey!
I just recently flashed twrp recovery and flashed some custom roms without making a backup of the stock ROM. Is there a way that I can flash the stock ROM and continue having OTA updates?
Thanks
I will assume that you have removed apps in you current ROM so before you return to stock you need to have a pre-rooted firmware will all the asus apps installed. Here is the link to the guide and follow the Pre-root stock method.

But shouldn't this method work?
http://forum.xda-developers.com/zenfone2/general/how-to-flash-ota-rom-twrp-t3209545
Do I still need a pre-rooted stock to flash the stock ROM?

I havent tried that method, but I think its the same. You can try it but be sure to follow it corrwctly and I read that it only works specific version of twrp. Read the thread and comment before doing it.

Yeah, that was the problem. I forgot I had to flash lollipop recovery and now it worked fine. I was also able to flash the stock rom with this method with marshmallow twrp but I had to flash the pre-rooted system image first through fastboot. Thanks!
I've managed to install TWRP on my phone.
I'm currently on nougat with s-on.
I want to root so I can flash custom rom but can't find instructions on how to do that. Could someone provide simple instructions on how to do that please. Also do I need s-off to flash custom Rom, if so how do I do that?
Thanks for reading

There is a N00b Help thread that is stickied for exactly questions like these.
You don't need root to install a custom rom. Most custom roms already come rooted. Instructions for flashing them are in each custom rom thread. Basically you do a backup of your stock rom in twrp (select system image and boot), and then flash your custom rom zip file in twrp.

thanks for that, just successfully flashed LeeDroid rom.
I followed this guide "[ROM][6.0.1]MODest Rom☆Multi-DPI☆Stock-Modded☆CQL1☆(1/26/18" to get to a custom rom.
I've been looking but can't seem to find a guide to get back to stock. Is it as simple and flashing the stock rom with ODIN?
Depends. Do you want stock w/locked bootloader/recovery? Then yes.
If you want stock unlocked bootloader/rootable that is slightly different.
