Fastboot differs on how it got implemented by OEM.
Try this
Code:
fastboot OEM unlock
to unlock device's bootloader.
Note: This requires "OEM unlock" got enabled in Android Settings -> Developer options & device got rebooted afterwards.

I tried fastboot oem unlock too same error.

I don't have this device but, your best bet is to post this question within the following Q&A thread that's specific to your device.

Bootloader block in the page.

Hello, I tried to unlock the bootloader several times, and was blocked, the page displays that too many attempts, how to unlock it? I care about time.
Thanks guy..
I'm sorry for my English.
Hello. Where exactly do you get "too many retries", in the webpage to request the code or in fastboot mode where you must type the command to unlock the watch's bootloader? What watch model? Can you share a screenshot showing the problem?

When you enter the unlock command, an error appears and can not be unlocked.
When he types "fastboot devices" he shows me "0123456789 fastboot"
when entering a command to unlock shows me

If you have the wrong code and you attempted to enter it many times then maybe there is some security mechanism that permanently locked it. I advise you to post your question, with screenshots if possible, in the unlock bootloader thread so other people with more experience about doing it can help you.

No option to update from ADB in recovery menu - HDX 8.9 3rd Gen

When I use ADB to reboot into recovery, there is no option on my device to update from ADB. (See picture)
I just want to wipe the device and flash the latest update to get it running normally.
Am I missing something obvious?
Thanks.

I've also tried going into fastboot and running the recovery command
.\fastboot flash recovery recovery.img
It returns with:
FAILED (remote: 'flashing not allowed for locked hw')
I'm guessing this has something to do with why ADB is not showing in recovery menu.

Stock HDX devices do not have a customary recovery menu or fastboot command set. If your device fails to boot and Amazon's simplistic reset does not fix it there is no recourse other than unlocking the bootloader (3rd gen) or tossing it in the waste bin (4th gen).

Fastboot detects device but freezes while flashing.

I am trying to flash recovery in my Poco F1 but fastboot stucks when running fastboot flash recovery recovery.img. Also while running fastboot oem device-info for a second time gets stuck.
Bash:
➜ ~ fastboot devices
c7ca2666 fastboot
➜ ~ fastboot oem device-info
(bootloader) Verity mode: true
(bootloader) Device unlocked: true
(bootloader) Device critical unlocked: true
(bootloader) Charger screen enabled: false
OKAY [ 0.001s]
Finished. Total time: 0.001s
➜ ~ fastboot --version
fastboot version 30.0.5p1-android-tools
Installed as /usr/bin/fastboot
➜ ~ fastboot oem device-info
this is where fastboot gots stuck when I ran fastboot oem device-info for a second time.
When trying fastboot flash recovery recovery.img gives error [Failed] fastboot flash failed no such device. If I try flashing after using fastboot --version, it stuck as described previously.
I tried with both Linux and Windows (Intel CPU) and the problem persists. I have already unlocked bootloader and previously(few months ago) flashed TWRP.

Question Nokia X20 stuck in fastboot mode after ota update

Hello,
A couple of days after buying the Nokia X20 it asked for an OTA update so I did it but it failed somehow and it booted into fastboot mode.
I tried through fastboot platform tools administrator:
- Flashing stock rom
result: "remote: did not have permission to flash"
-"flashing get_unlock_ability"
result: 1
-unlocking bootloader using "fastboot flashing unlock"
result: "FAILED (remote: 'unknown command')
fastboot: error: Command failed"
-wiping it using "fastboot erase data"
result: "
Erasing 'data' FAILED (remote: 'did not have permission to erase')
fastboot: error: Command failed"
PS: my only options are "Start", "Restart bootloader", "Power off". No recovery mode plus I can't take it to Nokia Care
I have no clue what to do next. If anyone could help it would be much appreciated

Your phone is fully bricked then! There's literally 0 WAYS to fix this issue, so you might as well just ask Nokia Customer Support to fix it. Sorry, but the next time you want to get a phone for tinkering and installing custom ROMs, just buy a Xiaomi or maybe a Samsung with good community support instead
