Fairphone 6 stuck in Fastboot Mode after locking with /e/OS/ installer

The next questions would be: what to do next and what can I do to lock the bootloader without getting stuck in the FastBoot Mode again?

try to reinstall e-3.2-a15, but wait for the soon e-3.3-a15 release to update /e/ before to try relocking again.

If there’s a simple step by step guide like the one you gave, I can surely do it.

in 3 copy / paste actions !

because even well illustrated, the “web-installer” often don’t work,

and because the official documentation is imbuvable for some new users.

here we take the Fairphone 6 as example,

Finaly,

only if the android security update in the previously installed Stock OS was older
than the android security update included in the /e/ build you want to install
you will be abble to relock the bootloader according to instructions at the bottom of the device install page (only possible with Official version)
