Help twrp

I have a Huawei P9 Lite and i have installed twrp and android 7.0 on it. Now I want to install Google assistant, but when i try to boot in twrp recovery (volume down + power b) it shows me the screen where it says ''Installing update'' and then freezes at 5 % so i have to hold my power button to power off the phone.
If I dont try to run in the twrp, phone works just fine.
I apologize for my bad english.

Hi there,
I will move your thread in the correct forum dedicated to Huawei P9 Lite for more relevant answers.
Good luck

Bump..
Just to state that I am in the same boat here; as I am facing the same issue. Here's what happened in my case (using a guide found here at XDA-Developers):
-- unlocked the bootloader
-- booted to bootloader and flashed twrp
-- used adb to reboot to recovery (adb reboot recovery)
-- used twrp recovery to flash nougat update (two zip files, one ~1300mb and second ~680mb)
-- had some errors that were expected, the guide said ignore them and reboot after both zips have been flashed.
-- the flash overall was successful as the phone booted in emui 5 with android nougat. However, there was no virtual keyboard; so decided to do a factory reset
-- rebooted to recovery, but this time, the phone booted to huawei erecovery
-- did a factory reset, but to no avail
-- now, i can't boot into twrp to flash anything else. booting into bootloader and using fastload to flash recovery image is successful, but the phone does not boot to twrp recovery; remain stuck on "your phone is booting up" (or something similar).
My phone is not bricked, as basic telephony, wifi and built-in apps are working fine. But, without a keyboard, its pretty useless for everyday use. Any help in this matter will be appreciated.

This seems helpful; but how can I flash recovery if I can't boot to fastboot?
[Update] Oh, got to fastboot, trying the suggested recovery now.

Fixed
Fixed using the suggestion above. Thanks.

Bootloader locks itself, can't restore via fastboot

Hi,
recently my friend asked me wether I can look at her P8 Lite which wasn't working after beeing left unused for some time. Basically when she got a new phone this P8 was left in box for a few months and after turning it back on the screen included in attachment appeared. https://imgur.com/a/WcvNByN I'm not new when it comes to unlocking bootloaders and all that stuff as I was doing it many times on another devices so I tought it will be easy job. Well, was I wrong... What I tried so far to recover this phone:
1) I obtained all necesary data to get the bootloader unlock code from Huawei. When I want to unlock the bootloader it works but after I reboot the device it goes back to "Locked" state.
2) It does not boot to recovery with buttons combination.
3) It does boot to fastboot but as I said bootloader locks itself down after reboot.
4) I tried to place UPDATE.APP from various firmweares on SD card and update it that way, it takes extremly long but with this metod it boots to some kind of MIUI recovery in which I have 3 options: wipe cache, wipe data/factory reset, rebboot system. Depending on firmweare it allows me to wpie cache or/and wipe data but reboot system always fails taking me back to this rescue mode screen.
5) Finally I tried to flash stock rom by extracting files from UPDATE.APP via fastboot. It flashes everything except recovery and boot which gives me fastboot error: "FAILED (remote: flash write prim vrl failure)". Interestingly I can flash TWRP recovery without error but when i try to access it whit buttons combination it fails and goes to rescue mode.
Device was stock and unrooted before this. I'm kind of out of ideas, I searched a lot of topics without any conlusion on this, if anyone could help me I wolud really appreciate this. However I think there is no hope for this phone maybe someone here would be able to help.

Oh no... You should contact Huawei and don't tell them that you tried to unlock the bootloader. Your phone may have a thing named "Huawei eRecovery". Launch it, it will download and flash stock ROM.

That option works only in China . I guess

I had the same error on my Huawei P8 Lite 2017 but I broke it myself.
The only way I was able to fix it by not taking it to a store was to use DC Phoenix,but it costs 20 euros for a 3 day license.
It was worth it though,since it did first of all lock the bootloader again,and it bootlooped at first but then I went to eRecovery and it installed the latest update and booted up.

Can't access Recovery, only fastboot and the universal bootloader, please help!

So after stupidly trying to update twrp through twrp instead of fastboot, I can only access fastboot and the universal bootloader installed on the phone. If I don't do anything, the phone simply goes through universal bootloader and I see a small penguin before the screen goes back and I need to restart the phone again. However, in the bootloader I can select to go to fastboot which does work. I've tried flashing TWRP through fastboot (fastboot flash recovery twrp...) and it said success however after clicking 'reboot to recovery', the phone once again just boots to the bootloader and I'm back at square one.
Thank you so much if anyone can help!

FYI, you can update TWRP using TWRP. Nothing wrong with that, I do it all the time. It's faster and easier to do so.
You might have an incompatibility between bootstack and TWRP.
So, please provide us more info.
ROM:
Bootstack used:
TWRP version:
What were you trying to do besides updating TWRP?:

Funny thing... I'm having the exact same problem.
I instaled TWRP (3.1.1-0-9c3b7e99) using the AxonToolkit 1.2.1.
Everything went smooth with the toolkit. I could get into TWRP and did some back-ups (as recommended), then wipe Dalvik/ART Cache, System, data, cache, and finally, try to install LineageOS 15.1.
I used the files:
- ZTE_A7LOSv1_UniversalBootStack.zip
- A2017U_OreoModem.zip
- lineage-15.1-20180810-UNOFFICIAL-axon7.zip
UniversalBoot and Modem were installed correctly, but I got an error when trying to install Lineage. I can't remeber the error number but it said something like: "this ROM is for device ailsa_ii_axon7 but this device is ."
Since then... my phone is in eternal loop and can only get into Fastboot. Can't access TWRP.
Thanks in advance to anyone willing to help me.

Don't mind... I have it back.
After many reboots, It only seems that this is working different with the Universal O bootloader. On the main screen, I tap the volumen button, choose "Recovery", reboot, press the power button on the main screen, press it again, the Linux Pinguin appears, press power button again, and then TWRP is back.
After that, I got to wipe and do the normal ROM installation process.

What am I doing wrong with flashing?

Hi folks. I have tried to upgrade the android release of a rooted P9 Lite phone.
(It had the 50%-to-1%-in-1-minute battery issue so I thought this would cure it)
Anyway, the working phone had vns-L22c636b120 installed.
So my faulty logic told me to go to update.highcloud.com site and download a full-ota image that started with the same letters, except with an image ending in something higher than 120. I downloaded the VNS-L22C636B384.
I did some fastboot flash operations on the phone, namely boot, system, cache and eventually recovery and recovery2, all flashes went fine, but the phone got stuck at "your phone is booting now". Only fastboot kept working. No recovery booted.
Eventually the phone accepted vns-L22c636b130 image and it now works.
My general question is: If I wanted to upgrade a Huawei phone's android version, what would I need to flash it with, and how? Obviously I am doing something wrong since the phone ends up stuck at the "Your phone is now booting" stage, if I pick anything with a higher number.
PS: During this flashing, I had no access to the recovery, therefore I was unable to 'wipe cache/dalvik' maybe that I was my problem. fastboot erase .... gave permission errors so I couldn't use that either.
Many thanks, -t

[Help] Bootloop after updating, usb debugging not enabled.

Using the miflash tool I flashed stock firmware (some version of android 8) after previously having a custom ROM installed. Everything worked fine until I rebooted after updating to the latest version using OTA.
My phone never got past the android one screen where it would freeze part way through, and after removing my sim card I could get to the pin unlock screen before the lock screen but after inputting the correct pin it would reboot and ask me for it again and again. I can get into fastboot fine but since usb debugging wasn't enabled and my bootloader is locked I can't reflash.
Booting into recovery also only brings me to a screen where the android mascot has a red triangle with an exclamation mark and a message saying "No command", so I can't factory reset.
Is there anything I can do to unlock the bootloader in this state or factory reset? (all flash tools and fastbooting into TWRP require the bootloader to be unlocked which in turn requires usb debugging to be activated)
Thanks for your time.

Update: I messed around with stuff on the cli based tissot tool and used option 2 to boot me into TWRP. It didn't do that but brought me into android where a system process kept repeatedly closing until a random factory reset happened.
I then got into normal android for a bit before I had to reboot (did remember to unlock the bootloader this time). I can now install twrp fine but every time I install the stock rom using miflash or try to install resurrection remix through twrp I get the same bootloop issue.
For some reason also my internal storage is completely empty no matter what i do so i need to sideload roms via sd card. And sometimes twrp gives me the error "failed to mount /system"
Trying the latest version of LineageOS next.

Update 2: if you have the same issue I had, the only working fix I've found is this restore point for twrp. Have not tried to update yet in case it breaks again but will make a final update with how that goes.
[SOLVED] Mi A1 BOOTLOOP
THIS PROBLEM IS VERY ANNOYING!! (The reason is because i didn't backup EFS before i flash Custom ROM) And I would like to share how to RESOLVE it. **your phone must be Unlocked Bootloader. Search Google how to do it. (Quick tip: in Fastboot...
