thank you very much for your answers, but I cannot unlock the bootloader, when I try to unlock the bootloader in fastboot I get the following error message: FAILED (remote:
Unlock operation is not allowed
)
So, it is not possible for me to unlock the bootloader in fastboot mode. are there any solutions for that?

I write fastboot flashing unlock. This is the complete code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flashing unlock
...
(bootloader) Start unlock flow

FAILED (remote:
Unlock operation is not allowed
)
finished. total time: 5.100s

If I write fastboot flash unlock, I get an error, that I did not select a partition.
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flash unlock
unknown partition 'unlock'
error: cannot determine image filename for 'unlock'

thanks, but they did also not work. It always shows not allowed
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot oem unlock
...
(bootloader) Start unlock flow

FAILED (remote:
Unlock operation is not allowed
)
finished. total time: 5.838s

C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot getvar unlock
unlock:
finished. total time: 0.004s

I also tried
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flashing get_unlock_ability
...
(bootloader) unlock_ability = 0
OKAY [  0.009s]
finished. total time: 0.011s

I am also not able to flash the system.img file, it says not allowed in this state
erasing 'system'...
FAILED (remote: not allowed in locked state)

thanks so much for your help
