[OnePlus 12] bardochu:
Sorry, I need help here, I have downloaded all files from page 1, I am going to change to CPH2581. and I unlock the bootloader, then I back into the fastboot and run the bat file, I have got something wrong. It's stuck in the process. I have checked I'm in slot A.

It's the following command that is shown in the process. Thanks a lot!
