Downgrade GSM Gnex to 4.0.2

Hello
Today i recieved the jellybean ota update. its not working. i searched for a while and found out that ill have to update it with something called cwm and this requires root, but i dont want to root my phone. so i thought it would be possible to downgrade my device but apparently this also requires root. I have an unlocked bootloader but is there no way to update/downgrade my device without using root?

cwm does not require root, just an unlocked bootloader.

dafuq? it was written everywhere so can please someone delete this thread?

can ota work unlocked bootloader

Does OTA updating work while bootloader is unlocked? Or does it not work only when rooted/custom recovery?

Having an unlocked bootloader does not interfere with accepting an ota, root, exposed , TWRP recovery and any other alteration will cause the ota to fail.

Thank you sir

I have a rooted device with f2f patch, twrp and supersu, can I still install the OTA?, or I have to restore to stock?
EDIT: the OTA i am receiving is nougat 7.0 (yeah, till today I am receving nougat...)

You have to reflash stock. Root and TWRP will cause OTA updates to fail.

Why would you take a chance and end up hard bricked? I gotta bang my head against the wall as you already have TWRP installed and you can flash my nougat stock 7.1.1 rom which has the July 1st security update.

ok, now I want to update to the december patch but one of the requirement is to have a nougat bootloader, but whan installed TWRP i had marshmallow. that means I have a MM bootloader because I never updated to nougat by OTA. I have an MM NANDROID I made with TWRP, how I can update my bootloader?
thanks in advance

Flash stock over rooted to get OTA

I wonder is it possible to flash stock unrooted OOS over rooted OOS in order to install small OTAs. After updates plan to root again. Does anyone know whether this is possible or not? And, any side effects could occur?
I search over internet and couldn't find any useful info about this.
Thanks in advance.

Technically you'll be updating your device by flashing the newest stock anyway. No need for OTAs. You can then re-root.

Not what i meant. Let's say I'm on rooted OB18. But i want to update it to OB19. all i have is OB18 stock firmware. So, can i flash OB18 over rooted OB18 and then update it to OB19 (ota). Then re-root.
The reason I'm asking this is i have a very limited data internet connection. So i can save GBs if this is doable.

Plan to keep a copy of OB18 around? If so, then yea absolutely it should work. Root will either modify your system or your kernel depending on the method, which both get overwritten if you flash stock.
Issue you'll probably end up having in the future though is that if you always use OB18, when it comes time to install OB20, you'll be downgrading without a wipe, which I don't think is a great idea.

No you can't.
Because OTA will fail for "partition mismatching": the systemless root alters only but anyhow the /boot partition.
You must update with FOTA (Full OTAs), doesn't matter you're using stock or TWRP recovery.
The OxygenOS built-in updater should detects your system as modified and download only FOTAs.

Let's say he has open beta 18, rooted and twrp installed, if he flashes ob18 again over it, this will get rid both of the root and twrp, resulting in an untouched system, therefore, ota after this will be possible. He can then flash back twrp and root the device

But practically speaking, it's crazy to unroot system only for OTA.
It would be more reliable to download FOTAs on rooted system.
Then, if @GTRanushka is running Magisk (MagiskSU) as root method, it could be working even after firmware update.
Because of its systemless nature.

This would be weird because I always had to flash magisk after a ota update..

In order to flash OTAS has to have stock rom but also recovery stock and bootloader blocked but not installed the OTAS otherwise it tells you that you have something modified and you have to download the complete rom. (That does not suit you)

You don't need a locked bootloader for OTA just have to flash stock full ROM zip and stock recovery then you're good to go

Why i try to unroot and do OTAs is the much less download size compared to FOTAs.

Well root yes. But if you delete the bootloader you will not be able to "load" anything to "boot"
In other words device will be just a brick

Well original state , Android has always had a bootloader. You cannot delete it.
Maybe you just want to unroot and relock bootloader?
This is possible. And answered in the thread. Do a search.

Couple of warnings first. If you are new to Android and rooting, you might not know, lot of times problems(bootloops) happen when you do not do it correctly.
If phone is not on full stock unrooted system then locking bootloader will cause phone to "brick".
Do you have reason to need it locked again?
Usually to unroot all you need to do is flash the stock boot.img if you are on nougat or stock Ramdisk if you are on Oreo.
Magisk manager has an unroot option that will work only if you installed root from twrp.

Well if what you want is to update. There is hwota for doing g that while rooted. And when it finishes you will be updated, unrooted, and if you want bootloader locked.

As long as you updated through the update center it's ok. Just don't use LG Bridge to update.
