when I download the stockrom and extract it, there are none of the files mentioned in the fastboot method. Why is this?! Is there a separate rom I need to apply? I have a oneplus 9 and it’s currently running lineage os with no ability to use the first method of applying an update of device (not when booted up and not from recovery either).
