RMA phone from Google is not unlocking the bootloader

It says it's unlockable, but fails.
Code:
platform-tools_r29.0.0-windows\platform-tools>fastboot flashing get_unlock_ability
(bootloader) get_unlock_ability: 1
OKAY [ 0.003s]
Finished. Total time: 0.009s
So then:
Code:
platform-tools_r29.0.0-windows\platform-tools>fastboot flashing unlock
FAILED (remote: 'Flashing Unlock is not allowed
')
fastboot: error: Command failed
platform-tools_r29.0.0-windows\platform-tools>fastboot flashing unlock_critical
FAILED (remote: 'unknown command')
fastboot: error: Command failed
If I factory reset, then oem unlock is allowed, but when I simply reboot to the bootloader, and start the phone after, it is greyed out. I feel like I am getting a false positive, except for the command above literally says it should be unlockable. fastboot oem unlock also does not work. I am skipping all options during setup and using Wifi as well only.
Any ideas?

There's already a thread about it. More than likely your rma is a Verizon phone and they can't be unlocked. Search and you shall find

I highly suspect Verizon model. A quick way to solve this is contact Google Pixel Support and give them the IMEI of the phone and ask for them to confirm if it is the VZW or Google Edition. I've done this a couple times to find a used Google Edition phones cause I've had a few duds. Phone support is the quickest, chat support has protocol that might make it hard for them to disclose that information.

[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.

hey, im on this exact thing. ive got the sim unlocked, but i need to get the unlock token. can you tell me how to request it from one plus? and did you get your bootloader unlocked?

Oneplus's website is screwed up and you can't download the token (it's corrupt) currently.
Use my msm conversion to unlock bootloader w/o token

Did you ever get your oneplus 8t unlocked? If not, I was going to suggest the msm tool to convert it to a EU version. I'll edit this post with a link. https://forum.xda-developers.com/t/...l-to-restore-your-device-to-oxygenos.4180981/
I've hardricked my oneplus 8t li ten times because I'm learning on my own. But I bring that sucker back every time. There are different msm tools, but ALL OF THEM that I've tried have worked every time. The only difference is what they convert it to. You can either "adb reoot edl" from home screen with adb enabled in the developers options or you can turn the phone off, let it sit for a minute, start the msm tool, then hold both volume buttons down for a few seconds and plug the phone into the usb while still pressing the volume buttons. The screen stays black, but you can see activity on the msm tool dashbord. I'm about to use it now, since my phone is currently hard bricked...lol. I've flashed shape shift os, lineage, icecold os, and some others. I have screenshots of all of them. Like shape shift, because it has a grip of hidden stuff on it, like easter eggs. It's hilarious. Just let me know if you need help.

New Case for Nokia 6.1 Unlock OEM

Hello, i read many post under this case, but i try to understand the reason why it's not working on Nokia 6.1 (2018).
Mine is a refurbished smartphone but i don't think it is the reason.
When i try to push the button oem unlock, it stay greyed and for sure the fastbook command doesn't answer other things that below ...
C:\adb-fastboot\platform-tools>fastboot oem device-info
(bootloader) Verity mode: true
(bootloader) Device unlocked: false
(bootloader) Device critical unlocked: false
(bootloader) Charger screen enabled: true
OKAY [ 0.016s]
Finished. Total time: 0.016s
Impossible to flash unlock or oem unlock.
Why flags can't be changed by other values ?.
What append witn Nokia 6.1 TA-1043, it's locked by HMD directly.
Any other solution than paid solution ?.
Thanks for your answers.
