I have a few old nexus 5x and 6p phones. The owners have since left the company and no one knows the password for them so I factory reset them but now they are asking for the account details for the google accounts that they were signed in to. As I understand it this is an anti theft feature.
I wish to install lineage OS on these devices. Is it possible to use adb/fastboot to install a custom ROM on these devices while they are in this locked mode?
