I did not experience using the Fairphone warranty after having manually installed /e/ OS. What I say just relies on the last paragraph of this page: https://support.fairphone.com/hc/en-us/articles/9979154556817
About the bootloader, yes you can unlock/relock it several times.
Thank you, this is what I need to know.
Be careful.
Always before locking the bootloader, check the result from āfastboot flashing get_unlock_ability"
If the result is 0 donāt lock the boatloader as you will brick your phone.

Have my Fairphone 5 (black Edition) since, 15. September at Home. Just played around with it and I like this concept and smartphone. Yes the camera is not the best, but itās for me more than ok.
Now Iām waiting for /e/OS to configure / install all my apps and start using the Fairphone 5 productive 
To use the ādefaultā Fairphone OS is regarding all google services a bit scary ^^
Hi everyone!
I got my FP5 today and well, it is an amazing piece of hardware.
Got the FP2 and FP3 and now 'm very hyped for using e/os with the FP5.
Any news if this is possible to install via easy installer?
I will make a review of the installation process, so yeah, Iām hyped!
Best regards,
Reini
Yeah, same here. I was considering buying directly from Murena, but the warranty terms donāt allow installing other OS, and as Iāll likely want to use other OS as well as soon as they become available, I refrained from buying there and bought at Fairphone instead, considering to donate the price difference when Iām installing /e/-OS without having the phone bought here.
However, thereās no visible progress on the Fairphone 5 port, apparently all the work is kept secret so far. As a developer, Iād prefer an open process, as I would also like to support the development and test pre-release software.
You could join the testing Telegram channel and get access to the test build as soon as it is ready for testing
Wait what? They are using telegram for this?
Where I can find the Telegram group link ?
I would love to take part, but Iām not using telegram since 2018. Very unfortunate 
I have a feeling this would be better suited as a (potentially protected) Thread here in discourse, just like Fairphone handles it for example?
Signal would be a good choice
Yeah, theyāre probably not going to change that procedure now, but maybe for the future. I donāt see why there should be any third party platform required, as I donāt see anything a thread in this forum couldnāt supply. Of course, Signal objectively better than Telegram, but then the Telegram people would be unhappy having to move to Signal. So maybe a thread in this forum would be common grounds. But until then, maybe someone can post on the forum if thereās some testing for the Fairphone 5 available
100% I also would love in partisepating with my fairphone 5. I donāt want to setup it now, because then I have to do it again with e/os
I wonder if it is not possible to have the testgroups here on the forum. Like Fairphone forum has closed groups for testing.
Exactly, thatās what I meant. I hope theyāre considering this for the future. Maybe we should open a request thread for that?
The testing group will remain on telegram for now.The reason behind it is very simple. It is easier for the team to follow up and get updates in real time on the telegram channel. We also get all the information in one place and do not have to monitor multiple channels and sites for the same information. This is especially important as we can pass on the information to the developers and build team members who can come out quick fixes to some of the issues faced during testing.
