Depends on the phone, many come with locked bootloaders
Many can be easily unlocked
But few can be relocked.
?? If you unlock BL by fastboot method, it's trivial to re-lock it.
The only non-reversible method is usually via manufacturer unlock portal.
Even when using another OS? Been trying to find info on relocking my /e/ OS install on my 1+7P and haven't had any love luck.
Cursory glance at XDA tells me that OnePlus devices need an unlock token for that device to re-lock the bootloader but you would have to roll back to the original factory firmware to do so.
Sucks that vendors can keep such a tight control on what you can do with your device. Would be nice to have the possibility to safeguard your device with any OS of your choice.
It's infuriating how few of them seem interested in holding the door open for us.
