Is it possible to re-lock the bootloader after installation of /e/?

Hello,

is it possible to re-lock the bootloader after installation of /e/ ?
On My pocophone F1, I only have on icon at boot that indicate, it’s unlocked.
But on a Oneplus3T, the message is a kind of boot menu…
Oneplus3T-unlocked

What is the consequence of re-locking a phone ?
Boot ? Recovery ? OTA Updates ?

Thanks.

As far as I know, this is only possible on FairPhones.

I think in your case, relocking would format the phone or require that you format it.

Probably also would require OEM ROM.

On the Fairphone 3/3+, to be precise.
The Fairphone 2 comes with an unlocked bootloader which can’t be locked.

That’s the case on the Fairphone 3/3+, too.
Unlocking as well as locking the bootloader will force a factory reset for security reasons. For a new install with a wiped data partition this would be of no consequence to any user data, but it might be troublesome later on, so if the device supports relocking when running /e/, it’s better to make up one’s mind about this at the time of a new install.
