fastboot oem unlock FAILED (remote: password wrong)

I've got my Bootloader unlock password from the Huawei website.
When I use adb reboot bootloader the phone successfully reboots into fastboot.
But when I try to unlock my bootloader I get:
Code:
fastboot oem unlock my16digitBLcode
...
FAILED (remote: password wrong)
finished. total time: 0.014s
I have enabled OEM unlock and USB debugging
Model: BLN-L21
Build: BLN-L21C432B368
Android 7.0
I also get:
Code:
fastboot oem device-info
...
FAILED (remote: Command not allowed)

and:
Code:
fastboot oem get-bootinfo
...
(bootloader) locked
OKAY [ 0.003s]
finished. total time: 0.004s
Why does it say that my password is wrong?
I've checked the SN and IMEI many times - and even used the IMEI2 and MEID on the Huawei website but I get the exact same unlock password.
The german customer service sent me the same unlock password.
I'm thinking about using dc-unlocker but I don't want to spend 4€ just to find out that it will generate the same bootloader unlock password that I already have.
Would downgrading help?
Or can I use kingoroot to root it?

Maybe FRP is locked,take a look at fastboot mode.

So weird that it keeps saying wrong password... Are you completely sure that it is correct? (I don't think that you can't read, it's just for being sure because that's what the command says)

FRP is unlocked when I have enabled OEM unlock in developer mode.
FRP is locked when I have disabled the OEM unlock option in developer mode.
I've tested it with both options but when I have disabled the OEM unlock it tells me that the command is not allowed.
I have checked the SN, IMEI and the unlock password many times.
I even used the IMEI2 and MEID on the Huawei website but I get the exact same unlock password.

Did you ever figure out what's wrong? I have the exact same problem.

No, unfortunately not.

I have the same problem

How much did you pay for it and are the 2 bootloader codes totally different from one another?
Can you check if there is a pattern between the two when you convert them to hex?

i used hcu and code was different you should try if your phone still with bootloader locked if you cant unlock boot loader i'll give you the 4 euros i paid 5 usd because i paid by paypal
but i'm sure you will be able because i said the same that dc unlocker or hcu will give me the same code but was completelly different and it worked !

This is because honor has disabled bootloader unlocking in all its current phones.
you will no longer be able to unlock it anymore...

Free bootloader Unlock key for Nokia 8.1

Disclaimer : I don't know Nokia fixed this or not and will this work for you guys but it worked for me and i want the developers to provide mass support for our Nokia 8.1 coz this is highly capable devices made stupid by HMD and fed up of lack of support by nokia
IMPORTANT: Do not verify your device on hmd unlocker app or it won't work for sure
step 1: go to website https://www.nokia.com/phones/en_int/bootloader sign in via Google(i did but don't think so it matters)
Step 2: Fill in required details asked and proceed directly on website and the website alone...do not verify ur imei on the nokia bootloader unlock app or this will not work 100%
Step 3: Agree all the terms and validate...u will get the unlock key from hmd global on email by which u signed in on Step 1
I am attaching the pics of the key i got...also it says it is the key for Nokia 8 but that's typo I guess but I assure u it works coz I unlocked my device also I relocked the bootloader and all the widevine works perfect after relocking the bootloader so no worries if you want to go back to stock also
I REQUEST ALL THE DEVELOPERS IF THIS WORKS FOR U GUYS PLEASE PLEASE SHOW CUSTOM ROMS AND RECOVERY SUPPORT FOR OUR NOKIA 8.1
THANKS IN ADVANCE

Is there any advice that ROM cannot be upgraded ? My condition is : I followed your steps to do but I couldn't flash unlock key. I returned system and found the "OEM unlock" cannot be enabled. That's why I cannot flash my unlock key.

Maybe its a possibility but low...although just found out yesterday that it depends on which production batch ur phone is made in....Nokia 8.1 manufactured in old batches have unlockable bootloader coz there imei is properly written
So its upon luck....which batch ur phone belongs to

thx it did work on my phone.

Hmmm, looks like site isn't working anymore.
I check the checkbox, but the log in to continue button stays greyed out, tried 3 different browsers.
Sadly, Looks like I have to pay for unlock. Am looking in lineageos development for this device. Too much free time after loosing job

Hi! Does anyone know how to lock the bootloader?
Previously, I experimented with installing GSI (PixelExperience, Havok OS, etc.). But as it turned out, the original system is much more stable than the GSI (although I may not have found the correct GSI
I want to return the phone to the state it was before unlocking the bootloader. That is, now I have the bootloader in the "unlocked" state. And I want it to be "blocked". Thus, the phone will be almost in its original form.

[SOLVED] Bootloader Unlock - Says it's flashing, but isn't?

Hello Oneplus friends!
My goal has been to get myself on the LineageOS ROM on these forums...and I miss the olden days just a bit =).
I got T-Mo to do the SIM unlock thing for me. OnePlus gave me the unlock_code.bin earlier this morning. It was like Christmas all over again! I ran "flash cust-unlock unlock_code.bin
I followed the instructions as best as I could to copy/paste all the commands from the main post, but doing "flash system system.img" turned into a bit of a mess, as it apparently didn't see the system partition to wipe. Naturally the phone wouldn't boot after this, so a bit more googling found me this page: https://www.oneplus.com/support/softwareupgrade/details?code=PM1605596915581. And, it did the wipe-and-reload thing that I expected it to, and I'm back to stock ROM...but, with a locked bootloader.
"No problem, the hard parts are all taken care of already!"
I go to the network settings, and the phone is showing as SIM unlocked. I enable USB debugging and OEM unlocking, reboot to make sure it takes effect, and then I reboot into the bootloader.
I then do "fastboot flash cust-unlock unlock_code.bin", like last time. I then get the following:
PS C:\platform-tools> fastboot flash cust-unlock unlock_code.bin
target reported max download size of 805306368 bytes
sending 'cust-unlock' (0 KB)...
OKAY [ 0.013s]
writing 'cust-unlock'...
(bootloader) Device is unlocked.
OKAY [ 0.010s]
finished. total time: 0.029s
That should mean the bootloader gets unlocked, right? I get the "are you sure" prompt, affirm it, and then I have an unlocked bootloader? That's what I'd expect...but the phone camps out in fastboot with the device state saying "locked", no matter how many times I reboot and redo this - same behavior. My computer says the phone has been unlocked, but the phone doesn't actually unlock.
Thank you for your consideration of this issue, and I hope this thread helps someone else in the future.
(edit: clarification - though the 'sending cust-unlock' command says 0KB, the file is 288 bytes so it is likely a rounding error. The file does have actual data in it)
Edit 2: aaaaand I'm a moron. Once that flash is done, THEN the "fastboot oem unlock" command works. Issue that, the confirmation prompt comes up, you've got an unlocked bootloader.
I'm leaving the thread here in case it helps someone else with lapsed memory; if the mods want to delete it, no harm, no foul.

Haha, I was about to suggest running the actual command, until I got to your edit.
Glad you solved this error.
I wish T-Mobile would let me unlock my phone!

Unable to unlock bootloader

Hello all, my first post in the OP8 community. I have a Verizon OP8 and I'm not able to unlock the bootloader. ADB seems to work fine and my device is recognized in fastboot. It gives me this error:
Code:
...
FAILED (remote: Flashing Unlock is not allowed
)
finished. total time: 0.002s
I've tried googling for answers, but everything is years old and seems irrelevant or just doesn't work.
I'm not sure if this helps, but "fastboot oem device-info" returns:
Code:
...
(bootloader) Verity mode: true
(bootloader) Device unlocked: false
(bootloader) Device critical unlocked: false
(bootloader) Charger screen enabled: true
OKAY [ 0.004s]
finished. total time: 0.005s
Any recommendations? I can't understand what I'm doing wrong.

Perhaps the answer is in here:
OnePlus8 VZW Bootloader is Not Unlockable
Has anyone seen any difference in the bootloader, unlocking, rootability on the Verizon Version of the OnePlus 8. Anything in coding that speaks to a lock out from Big Red? I heard about sign up and IMEI issues with the direct OnePlus buys...

This can be handy for your Verizon OP8: https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4191723/
Also maybe some insight on how to bootloader unlock and root your phone: https://forum.xda-developers.com/t/guide-android-11-how-to-root-t-mobile-op8-5g.4228303/
TIP: Go into Settings>Wifi&Network>SIM&Network:> Network Unlock. This should get your phone unlocked which is the first step. I have Tmobile OP8 but I think it's the same UI across all OP8s.

OEM unlocking enabled, still can't unlock bootloader

I have an unlocked variant of the Pixel 2. I put a Verizon SIM in it, and because of that, OEM unlocking was grayed out. However, a factory reset allowed me to enable it in developer settings. But when I tried to go to fastboot and unlock the bootloader, it kept giving me the following:
Code:
FAILED (remote: 'Flashing Unlock is not allowed')
Then when the phone is rebooted, the option is sometimes grayed out again, but it sometimes it stays on. It is running Android 11/RP1A.201005.004.A1/6934943, latest securiy patch.
On Verizon's site, the IEMI reports GOOGLE PIXEL 2 NON-VZW.

Hi i have the exact same problem. Looking for a solution...

I read on a Google forum that if your IMEI starts with 35 then it's an ex-Verizon phone so the bootloader is Verizon. Can you guys confirm that yours is 35* too?

I have the same problem on two Pixel 2 devices one is from Verizon the other isn't and has OEM unlock. They both start with 35 and both won't unlock the bootloader. Can you post a link to the Google forum post? I would like to read it.

has anybody found a solution to this? Why is this only appearing recently? It seems that these phones might have been flashed with incorrect firmware or a bug in the firmware?
