Stuck after unlocking bootloader? - Huawei Mate 9 Questions & Answers

Hi everyone,
Today I decided to root my Mate 9.
I started out with turning 'OEM unlock' on and usb debugging. With ADB installed and the huawei drivers, I began to unlock my bootloader. On the 'EMUI Huawei' homepage I filled out my device details and obtained an unlock code. I opened ADB and checked with 'adb devices' if my device was there. It was. So I continued with typing 'adb reboot bootlader'. After that I typed 'fastboot devices'. My device was still showing up. I typed 'fastboot oem unlock CODE (with the code). On my screen I pressed 'Yes'. Bootloader unlocked.
After this step I tried to flash twrp with the command 'fastboot flash recovery xxxx.img'. I couldn't continue because every adb/fastboot command keeps failing (remote: command not allowed). Now when I boot up my phone it shows 'your device has been unlocked and can't be trusted'. Phone=unlocked, FRP=locked. I can't do anything.
Device: Mate 9 L29C432B198
What did I do wrong or what did I missed? :crying:

I had this issue at first to had to redownload the original rom via the phone recovery this will fix the frp lock then u have to unlock and flash twrp 3.1.01 that is linked in the threads on here

Did it format after it unlocked?
You can try fastboot oem relock UNLOCKCODE
Then go to Settings -> Dev options -> enable OEM Unlocking
Then unlock again.
It probably will fail though if FRP is locked, but worth a shot.
Edit: It's supposed to say
PHONE Unlocked FRP Unlock

[Q] Unrecoverable bootloader error - Bootloader locked

Hi,
I would like to know if there is anyone who knows how to unlock the bootloader on a TF300T with the Unrecoverable bootloader error. I have access to fastboot, yet the "fastboot oem unlock" command doesn't unlock the device.
The entire device is wiped due to following another tutorial for fastboot to recover from the bootloop error, so there is no more way to enter recovery or cold start android... the device has two options, fastboot mode, or being stuck at the asus logo untill the battery runs out. Adb doesn't recognise the device, even with windows drivers installed.
I can't flash anything with fastboot as the bootloader is locked.
Is there a way to unlock the bootloader, or is it gonna cost me repairs?
Grtz

Which method you used for unlocking bootloader and which phone you are using

Can't unlock bootloader

So I got my new U12+, bought the unlocked version, I'm pretty sure when it updated it became locked??
Anyway, went to HTCdev to unlock and I get this message when I try
Security checking failed DENY
Shows it as locked S-ON
Should I reset it then get S-Off?
Sounds like you might be confusing a few things.
The Unlocked version is the sim-unlocked. The boot loader will be Locked S-ON. Two different things.
Now to unlock your boot loader to run custom software make sure you follow the steps exactly on HTCdev website.
Get your token key while in Download Mode, copy and paste the correct parts. Then unlock once you have the correct unlock token bin from HTC.
Unlocking your boot loader is all down while in Download Mode. Make sure your have OEM boot loader unlock enabled in Developer Settings.
What a dummy....
OK, de-bugging on and OEM unlocking is enabled.
Tried the steps at HTC and got no response from the phone after typing the get identifier command
I'll try again
BTW, is it just me or is it a pain to get the button sequence just right?

Click to expand...
Click to collapse
It's annoying. But if you have adb on your computer with Debugging enabled within Developer Settings.
adb reboot bootloader
Thatll save you a few a minute or two
OK, so now I'm stumped again,
adb reboot bootloader
phone reboots as it should
fastboot oem get_identifier_token and nothing
<waiting for any device>
Never Mind, took a few tries and new drivers, we're good to go!
How were you able to resolve it? what drivers should i download? I tried twice and i am getting the same message:
Error Code: Invalid Bootloader Token Length.
Error Reason: The submitted Token appears to be the wrong length and won't work.

Unable to Unlock Bootloader (help!)

I've tried online guides to unlock bootloader, but messed up in some point and now I'm stuck.
1st. Download indepth test and reboot to bootloader within the app.
2nd. Tried adb devices successfully
3rd. Fastboot oem unlock nor Fastboot flashing unlock run (output: fastboot oem unlock failed "remote unknown command")
4th. Decided to make a factory reset (just becase I had to make an stupid desition)
Now I can reboot into fastboot again, because in depth test app won't install anymore. Installer says "Installation failed -An app with the same signature has already been installed"
I've unsuccessfully tried to flash stock rom from recovery but thein depth test seems to be "installed" without front user interface, also fasboot reboot bootloader get stuck in waiting for any device.
Can someone have a solution I already tried anything that comes to my mind.
Thanks.
I was able to solve the problem installing extractly the same apk.

MSMDownloadTool messed up my phone

Used MSMDT to reset to TMO firmware on KB2007 (OnePlus 8T) and now bootloader is locked and unlock token doesn't work again "FAILED (remote: 'Error - Verify Failed ! (4:-2)')" and my bootloader is permanently locked. Any help would be appreciated.
The MSM Tool returns the device to the way it was when you took it out of the box and booted it for the first time. Do you have USB Debugging enabled in Developer Options? You only need the token once. Have you tried using ADB to unlock the bootloader?
I checked oem unlock in the settings, and then tried to flash twrp and got an error saying the device was locked, tried fastboot oem unlock, and it told me to flash the unlock token, but it won't accept the token.
Try requesting another through OnePlus Support then.
