Hey Fairphone-Community,
Hi @yvmuell
yeah, my 1st post will begin with a question as I already read for a few days now, because actually I wanted to install /e/os on my phone and while I saw that it should run /e/os without problems I also bought one, but without the preinstalled OS from Murena.
Now I’m a bit confused and/or afraid at the same time, because I read this “brick” stuff all the time.
I haven’t flashed anything yet, but unlocked the boot loader and afterwards I trapped myself in a boot loop, which is not a brick, as I thought before.
What I did was changing the boot slot from b (which was default) to a.
So now here is my question: Is it really possible to brick the device completely or is it always possible to install any bootloader with adb or change just change it to the non-default slot (to a in my case) and work with that.
I thought if the device doesn’t boot anymore, I always could change to b and do whatever I want.
(like a backup bootloader) - I heared about that on Google- or Samsung-Phones.
So I never had the risk to brick my device completely.
At the moment I can’t install /e/os because of a message saying so from /e/os-Easy-Installer (idk why), but if I really can brick my device I’m not in the mood for that even though I’m disappointed about the display, not even 90Hz…
That would be a really expensive “Briefbeschwerer” for me… 
I hope you can clarify or make me calm myself 
Best regards to ya’ll.
