That's to enable you modify /system partition?

So first i enabled usb debugging and oem unlocking in developer settings.
then i booted my live usb and downloaded the moded fastboot file. (Opened the terminal in that folder)
cmd that i used:

1. sudo -i
2.sudo usermod -aG plugdev root
3.cd /home/ubuntu/Downloads/modified_fastboot/
4.i booted my device into fastboot
5../fastboot devices (my device was shown in terminal)
6. ./fastboot oem get_identifier_token
...
(bootloader) Identifier token:

(bootloader) 30363531323335313734303034363038

7. ./signidentifier_unlockbootloader.sh 30363531323335313734303034363038 rsa4096_vbmeta.pem signature.bin
