Question on how to upgrade official firmware on Rooted device

Hi,
I have rooted P10 Plus L29. Currently, it is on B133 and I want to update to B162. I did some research on how to update and found several methods (Link ).
I used HWOTA method when I update from B131 to B133 but unfortunately the bootloader is locked again after updated. To unlock bootloader, it will wrap all data from the device.
So, I just curious about the other method whether it will lock bootloader or not. Any suggestions on this?
Imho it is not possible to update without relocking bootloader.

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.

How to downgrade to stock from soak test oreo

So I installed Oreo soak test on Moto G5 plus which was shared by link over stock Nougat build with august security patch.But i want to go back to nougat with august security patch from this soak test build...How can i do that without bricking and losing imei etc.I have not rooted or unlocked bootlader ever...and yes i read some threads but none of them are matching my current situation ,so please guide me through proper process .
Well I'm in the same situation. And I was having wifi issues. Bt I managed to fix it. From what I've read so far you cannot downgrade the bootloader. So you can flash using fastboot bt leave out the gpt and bootloader commands. I'm not sure if this will let you download OTAs. I haven't tried it out yet. Or if u manage to get the C092 bootloader unlocked ( some people managed) then you install TWRP and flash a stock nougat zip. Or you will have to wait for someone to capture the actual 85-16 OTA , make a zip of it and then update. There was a guide for flashing, it was for g4 series to downgrade from N to MM, the commands should be the same. Hope this helps.
Can anyone share official oreo update zip?Not talking about soak test one.

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.

Moto G4 Amz Version

Hello, i would like to ask here if someone has the same issue, i had a fully working Moto G4 AMZ Version Running Nougat, however after waiting too much and the oreo version never was released, i wanted to try to flash the firmware and update it via rsd lite with oreo version, however this resulted in my phone bricked, i tried some ways to downgrade again to nougat however i was not able since it is not possible to downgrade to stock amz firmware once i had updated it with wrong version of 8.0, so may i ask if after maybe 1 year is there any advance or release for the 8.0 amz version firmware? i think the only solution for this is to send the device back to motorola, but i will ask first here any other ideas?
Thank you in Advance
Henser.
Use lenovo save and rescue to unbrick your phone.
I’ve tried installing stock moto G4 Android 8.1 and no luck. This is with boot loader unlocked, custom kernel and root. No luck.
same issue, i try from time to time to recover the device with no luck, still waiting for a solution with bootloader locked
