So I really want to install a custom rom and I know I need to unlock the boot loader and flash it with twrp. But I been reading around here and it seems unlocking the bootloader on Oreo is not possible and the only way to do that is to downgrade to nougat... except I don’t really know how to do this on my device since as previously stated, the boot loader is not unlocked and I don’t know where the stock rom for nougat is even available to download from, or any necessary tools to download to be able to do this (I’m a complete noob). Some info of my device: A2017u, Oreo, B20
Help would be appreciated, thank you
I think you may need to go back to Marshmallow to unlock bootloader and install TWRP but I'm not on an A2017U so won't try to advise you.
I did revert my own A2017G from latest Oreo back to Nougat ok. Since gone back to Oreo. It seems to work when stock but once you meddle with it that's when all the problems start.

Hi, newbie question here. I just got my Axon 7. Unlocked the bootloader. Installed TWRP. Made full nandroids of stock and rooted firmwares.
I would like to flash the new Nougat update. What would be the best way to accomplish this without losing TWRP? and what is the correct firmware to use? ota? Also can nougat be rooted? Just dont want to brick my new phone. Thanks
No TWRP flashable file yet.....but I'm sure it'll be soon.
You will need to be on the Nougat bootstack, but you'll have to search for that info.
Hi all,
Noobie questions sorry.
I have a xt1625 us retail version and I'm getting prompted to take the OTA nougat update.
However, I have unlocked bootloader and TWRP installed so it fails.
1) Is the stock nougat available as a zip?
2) Is my best option to relock bootloader and go back to stock recovery, in order to take the OTA?
3)Is there a stable custom rom that is preferable?
Thanks very much
update;
I reflashed the stock firmware using fastboot and the 16 ish commands needed.
After this I took the OTA update without issues.
You can re root your phone and reinstall twrp now.

Try to remove root and lock the bootloader, and search for the B380 OTA again

On which rom you are?
If its some emui just search somewhere in here for firmware finder tutorial i used it to update to 380 (i had root and unlocked bootloader) and if you are on cm you shoud have backups (atleest if you did everything like all tutorials said) and just restore back if you don't know search
If you are on any other rom look up post from which you flashed it... Usually there is written how to get back
go to huaweis support site and find your phone. under downloads they have stock rollback package and stock firmware. download both and you will find a guide inside the downloads. then you're back to stock
Hi,
Right now i am on stock EMUI 5.0. My version is VNS-L21C432B370 but i have battery problems which i think B380 can solve but since i am rooted and with unlocked bootloader i cant OTA update.
I think getting the VNS-L21C432B380 full ROM i can update with 3 buttons method but i cant seem to find that ROM nowhere.
Can someone help?
Thank you
Hey,
I have the VNS-L21C432B380 full rom (stock) with an unlocked bootloader and unrooted. If there is a way to backup it without unlocking b/l and rooting, PM me and I'll get you sorted. Cheers!

Hi,
Stayed up late yesterday to prepare this for you. Hope it works as I flashed Arsenik and would like to safely go back in case something goes wrong.
Let me know how it goes..

I have Custom ROM stock nougat
Can I install only the MM bootloader, do full wipe, and install a custom MM ROM, just for recovery?
Downgrade for recovery?
I'm confused about what you want to achieve, are you asking if you can downgrade to stock marshmallow from stock Nougat, to flash a custom marshmallow ROM?
If so, you could downgrade, but I would strongly recommend not using OTA updates on the stock marshmallow ROM if you downgrade, else you may hard brick your device. In most cases, you can't downgrade the bootloader in fastboot.
I'm not sure what you are asking for about recovery, can you elaborate?

You can even stay on nougat firmware, there's no need to downgrade as nougat is official released and available for all countries
if so, which version or file should I use?
thanks in advance.
@josuemf: Downgrading is easy peasy, no issues at all. You can even go all the way back to Marshmallow if you want. Just flash a stock ROM EDL of your choice.
