[Help] Noob trying to root Huawei P9 Lite VNS-L31 (B239)

Soooooo, here it comes
Trying to root my Huawei P9 Lite VNS-L31 (Compilation VNS-L31C02B329), but I can't make it to boot from TWRP
Android 7.0 Nougat / EMUI 5.0
1 - Already unlocked bootloader
2 - Already installed all those Huawei Drivers / ADB and all sorts of things
3 - Already usb debug mode ON and also OEM unlock active
4 - Already used the adb flash recovery recovery.img
5 - After the steps above, rebooted device in bootloader recovery, but it never goes to boot TWRP, only to Erecovery Huawei
Can someone help me, step by step, how to make the system boots first to TWRP and skip Erecovery Huawei?
Many thanks

The command is fastboot flash recovery recovery.img

yes, sorry, I used this one, it even appears the the file being flashed to device, but the problem is when I try to boot it, goes all the time to erecovery, not to twrp thing. Is it possible to skip or change priority to make it boot twrp first?

What TWRP did you use?

I've tried a lot of them (3.0.2 was the last one, if I'm not wrong), but all seems not being working
I wonder if I'm not doing something wrong when restarting the device, maybe I'll try again some steps, but if someone here could give me an precise step by step and a 100% guarantee twrp file, maybe I could figure out what was wrong
Do you know someone whose cellphone is the same as mine?
Many thanks for your attention, I'll do my best to follow your instructions

Use this one:

VNS L31 Unable To Start TWRP Recovery \ ROM Question

Hi Guys
I finally manage to unlock my bootloader on my VNS L31 unlocked. I have flashed the TWRP Recovery tool, but I'm stuck on the Booting... text if I press Volume Up and Power. If I do a normal boot, the phone boots as per normal and I can access the OS. After looking around it seems like its because I'm using Android 7.0 - and have tried a few Nougat specific TWRP builds. None of them worked.
Can anyone please point me in the right direction? I'm looking for a TWRP recovery tool that will work, as well as a working root method.
Bonus Question:
What custom ROMs do you guys recommend for the VNS L31?
My experience with the bootloader unlock code that might help some people:
I tried the Huawei request form, but it just gave me errors. I also emailed them twice, but they refused to give me the code. What I ended up doing was using DC Unlocker. It sucked that I had to spend money, but at least it worked... I hope this might save some people from getting super frustrated.

Hi,
It's simpler for you to install directly a custom rom with (include) TWRP recovery and root methode (magisk is cool).
In my personal experience, EliteRom is the best at the moment, the next version was coming soon, please wait (v5) and install.
Advice: reinstall a clean and untouched version of Emui before flashing a custom rom (Elite Rom ).
Follow my guide HERE
EDIT: is not difficult to obtain a OEM code with Huawei website, just try on Chinese version and done!
Good luck!

Flash @OldDroid TWRP from fastboot:
Code:
fastboot flash recovery recoveryname.img
Then reboot to android:
Code:
fastboot reboot
You need to have adb installed on your pc.
I recommend the 15 second ADB installer .
Enable usb debbuging in development settings and give authorization to your pc by confirming the prompt on your phone.
Then using adb reboot to recovery.
Code:
adb reboot recovery
Hope it helps

NEED REAL HELP! MOTO X PLAY Bricked! :( :(

I just wanted to root my phone, but got stuck when I tried to flash a Supersu using TWRP recovery in my phone.
Things I did before trying to install supersu:
1. Unlocked bootloader
2. Installed twrp through fastboot adb
From then, I tried multiple different things and now I am stuck with these issues:
1. When I try to fastboot some firmware using ADB and fastboot, I get this message on every line "Pre flash Validation Error" and "Remote error" something
2. When I tried to install a rom through TWRP recovery , I get some other error there. Ill update on the error in a few hours.
Basically, I was using Android 7.1.1 when my phone was working properly. Please tell me what to do? I don't know what I am doing. My phone is stuck at "Unlocked boot loader" screen.
Please help. I have a MOTO x PLAY dual sim card version!!

Unlock bootloader then search moto x play twrp.img(3.1 or 3.2) file then flash magisk.zip.

Don't use SuperSU. Use Magisk 14.0 version stable and good.
First flash the zip file from TWRP 3.1.0 or greater, then install the Magisk Manager app.
I too faced the same issue with X Play/SuperSU. Finally i resolved the issue by writing some code in terminal.
But i prefer Magisk over SuperSU. It won't give any issue.
But if you want to use SuperSu. First write this code via terminal then flash zip.
echo SYSTEMLESS=true > /data/.supersu

[X01BD] Can't install TWRP after unlocking with Official UnlockTool

Hi guys,
I am using Zenfone Max Pro M2. I wanted to install a custom rom and I tried to unlock bootloader but I unlocked it through official unlocktool. Now I can't flash anything or send any command through fastboot, whenever I do then it restarts the device.
When I try to keep the fastboot command running and then connect phone - it throws errors like "Fail - Too many links", "Fail - Write to device fail (No such file or directory)" or "Fail- Unknown command".
I tried unlocking bootloader with the unofficial way provided in https://forum.xda-developers.com/max-pro-m2/how-to/unlook-bootloader-root-asus-zenfone-max-t3885457
but it isn't working either, any fastboot command is rebooting the device although bootloader is unlocked.
How do I fix this?
EDIT: Things I have tried:
- Changing USB Cable and Port
- Reinstalling ADB and device driver
- Reunlocking bootloader from UnlockTool (don't know why I did that again)
- Unofficial way to unlock bootloader
None of it helped.
Thanks

Did ur unlocking bootloader succeed?

Did you try relocking the bootloader ?
1) Try relocking the bootloader using the methods described here :
https://forum.xda-developers.com/max-pro-m2/how-to/unroot-relock-bootloader-max-pro-m2-t3885870
See if it successfully relocks...
If it does, then next time unlock using the unofficial method only...
2) If not then maybe try contacting ASUS... Tweet them on Twitter... Companies usually respond very fast on Twitter, since their reputations are at stake...
3) All else fails then try rooting it using something like Kingroot... Once rooted, flash TWRP Recovery using Flashify... then flash any custom ROM u want...
I hope your problem gets solved... Next time be a little more cautious when taking such a risky step... See what are all the options you have before jumping into something...

I guess it did because when I reboot it I get that bootloader unlocked splash screen.

Tried everything except 2, none worked. I'll drop them a query over twitter like you say, let's see what their reply is.
I am on stock recovery, non working bootloader but unlocked, and stock rom unrooted.
I think Pie update may give some insight on fixing this.

I see.. did u've try using another laptop/pc? Sometimes antivirus blocking the tools that are needed for unlocking bootloader..

I unlocked using official bootloader apk provided by asus. Now I have encrypted phone which isn't decrypting and can't flash twrp.

Hey you said phone is encrypted ? Maybe this might work :
1) Download and install the latest Magisk Manager apk
2) Extract boot.img from stock firmware
3) Put boot.img in your internal storage and open magisk app.
4) Click on install and select patch boot Image.
5) Select stock boot.img file placed in phone memory.
6) Magisk will automatically patch the stock Image and this patched image can be installed using fastboot using this command:
fastboot flash boot patched_boot.img
This will root your phone. After that you can install Flashify to flash TWRP or PBRP
Note:
- This method is highly experimental... There are 50% chances of bootloop. I would not have recommended this method, but situation seems to demand it.
- Your data will most probably be formatted, so keep a backup.
- If it falls in a bootloop, then you need to flash original stock firmware to restore your phone.

Who came up with this method, but removed it from the main guide, because of being experimental... (I guess)

After going through the errors, I strongly believe that the problem is with your drivers. If reinstalling doesn't works, try a different pc. If your pc detects your device on MTP or your are able to perform adb operations without any hassle, it's not the problem with your phone.
You can decrypt the device only after flashing custom recovery.

Yes this method is highly experimental. Also in this situation, he cannot use any fastboot commands. So this method won't work

This method didn't work, as fastboot isn't accepting any command. I tried giving command before connecting phone and then connecting, it gives me error of "File size is more than max allowed".

So is it done?

I've the same problem too. Let me know if you've configure it out. Thanks.

Okay @Mr147, I've fix this. I checked Windows Update and there was a pending ASUS driver update. I downloaded it and now I can use the fastboot commands.

Anyone that can fix this problem? I also experience this.

TWRP Invalid partition name recovery

Hello guys, I have a Moto G6 Plus 4GB+64GB Brazil, and I'm trying to install the TWRP on it, I managed to unlock the Bootloader normally, but I've tried all the ways to install the TWRP and I can't, I've updated the Motorola Drives, the programs, and always do the commands in the CMD, displays the message: Invalid partition name recovery.
After that I can only connect it again by restoring the ROM with android 9.0.
I am trying to install to root it. I've tried to do the root installation without TWRP but without success too.
Does anyone know how to fix this error? Thanks

With this phone you need to first boot twrp via command: "fastboot boot twrp.img" , and then use a zip file to fully install TWRP. you can find this zip here on the forums.

From where did you get this twrp.img? Download the official build from twrp.me., they have a installation guide.
