Unlocking bootloader HTC Tattoo -Spain

I've an HTC Tattoo and I'm trying to unlock the bootloader with the HTCdev bootloader unlocking. I do everything they say to do, but when it's time to put this command:
fastboot oem get_identifier_token
I get this error:
...
(bootloader) [ERR] Command error !!!
OKAY [ 0.007s]
finished. total time: 0.008s
I've removed and inserted the battery lots of times, reinstaled the drivers, searched information, but I couldn't find any solution.
I've S-On. I suppose it's not a trouble.
Thank you in advance!, you'll help me a lot!

I have the same issue with my HTC desire Z.
It shows following error:
...
(bootloader) [ERR] Command error !!!

Is there another way to find identification token?

What happens after reboot, try to boot to recovery with volume button, when you use
Code:
fastboot flash rescue_recovery_ramdisk RECOVERY_RAMDIS.img
recovery_ramdisk
does phone still have your broken twrp or the stock recovery?

HI, You said if you could put stock recovery then you can unbrick yourself. Can you elaborate on this please? Also, you tried the load method with the update.app so can you tell me where did you get that file? I'm in the same situation. I locked myself out completely trusting that the dload update.app method so that I could go back to complete stock as I was stuck in the emui 8 beta earlier with twrp installed with twrp backups. I have stock recovery "RECOVERY_RAMDIS.IMG" installed on my phone. I flashed it to get rid of TWRP so I could be on stock recovery.
I flashed stock recovery, relocked bootloader and tried the dload method and every time it fails at 5%. I'm using BND AL10C675 (INDIAN) so now I can't unlock bootloader because I need to enable "OEM unlock" in settings and I can't do that cos I can't boot into system as the system is formatted (NO OS) and so I can't install twrp or any system images nothing. I just locked myself out and I can't believe it. **** does happen

Question No way to unlock bootloader?

I got a ROG phone 6 few days ago. But I found that after I used the official unlocker app, I cannot find OEM unlock option in Developer settings.
I tried 2 commands in bootloader:
Code:
(bootloader)
fastboot flashing unlock
FAILED (remote: 'permission denied')
fastboot: error: Command failed
get_unlock_ability: 0
OKAY [ 0.003s]
Finished. Total time: 0.004s
How can I enable it?

To unlock the bootloader, you have to use unlock app from the Asus homepage. That's the best way to do it. Relock could be done by CMD command.

I also cannot unlock my bootloader. When i use unlocking tool app my device just reboot
