I tried downloading the B19 build and it's saying signature verification failed in stock recovery. Is there another way to do it? Do you have a link for another build?

Uhh try not using stock recovery, just go to Settings and Updates
But you need one of the full updates (~2.5gb) and original from ZTE. and unzipped

Same process as rooting the previous build. Flash SuperSU in recovery. Pretty basic.

Only if you want to use traditional root, which has been discontinued. Systemless root patches the boot.img for you, so all you have to do is flash the zip.

Yes, if you want to root the stock ROM. If you're going to flash a custom ROM just unlock your bootloader, install TWRP, and install the ROM. No need to flash SuperSU first.

No. Unlock bootloader/flash twrp/flash rom of your liking. Just like @Hisenberg said. Make a backup of your stock rom before you wipe and flash a custom one though just in case.

Yes. It does not rely on root. Just unlocked bootloader.

Yes it does. TWRP is what you use to flash SuperSU, which gives you root.

Yeah, but you don't need root to use TWRP. You can flash zips, custom ROMs, kernels, etc all day and not be rooted.

I can probably see right now, you've done it wrong... Download stock rom from huawei.consumer... For some reason i thought it's gonna be android MM, but it was android N, so no problem here, just download stock rom and you will have newest android.
You probably downloader rom from xda, rom it's in .zip right? And you tried to flash it with TWRP?

Yesterday I had this issue, it's more easy than it seems. In Revolution Recovery for Nougat, flash the update.app ZIP with 6.0 , it will show you a lot of errors, but don't worry, it's ok. After this flash than DUALSIMOEM.zip and after that shutdown your phone and use the 3 buttons method to automatically ,,update" to B161.

That's because u don t have the bootloader unlocked Also, verify in Developer Options to have Enable OEM on, that's why you have an error in CMD

OK you have ways of possibly bypassing this issue.
One is to root the device. This will patch the boot.img and disable dm-verity.
Or use an eng boot.img.

Flash the entire combination firmware. Enable OEM UNLOCK and Factory reset from within the firmware.
Then try reflashing the stock firmware.

Totally Bricked?

I Have an Huawei P10 lite with Elemental EMUI 8.0 rom...TWRP Recovery. my Phone rebooted by itself. Now i cant boot the os and recovery...no erecovery ..and Fastboot says Phone locked and FRP lock. Is my Phone totally fkd now or can i unbrick it?
Yep. It's almost totally fkd
You can unbrick it by DC-Unlocker + HCU Client with their support, but the whole service will cost you a lot of money!

you can use magisk 18 also
I just recently installed b20, had trouble installing it had to oem lock and oem unlock in b15 edl then update through official recovery to get the thing to install. Well the playstore store now shows device not certified on a clean install, im guessing its because of the oem unlock.

Thanks. I was able to get back from Oreo to Marshmallow via Jcadduno's instructions in the rom/kernel sticky. Used MiFlash + B19 EDL package and then was able to get into fastboot & oem unlock.
I'd like to get to a state of stock Oreo + TWRP + Magisk. Has that combination been achieved by anyone?
Is your playstore certified? Cause on my clean install before i installed any other stuff showed device not certified.
