e/OS Easy Installer leaves bootloader open

Hello forum, I am new here. I have experience with a flashed FP4 with e/OS. Now we have tried this with the FP5. We used the Easy Installer for Fairphone 5 with Ubuntu 22.04.4. The process worked, but the bootloader remained open. There was no dialogue to close it. Why is this, can anyone say, and is there any way to close the bootloader now? Thanks for help.

fp5 was introduced to Easy Installer v0.20 about a month ago and withdrawn a day ago in v0.20.1. (Source https://gitlab.e.foundation/e/devices/easy-installer/-/tags.)

If you search “brick” within fp5 there have been some issues, sometimes these involve bricking which seems can only be undone by Fairphone or their repair contractor for a fee.

If you check the manual install instructions https://doc.e.foundation/devices/FP5/install you will see this warning within the locking section

Caution: FP5 comes with an anti-rollback feature. Please read the paragraph marked Caution in Requirements section of this guide, before you proceed to install /e/OS on FP5.

Users acquiring an FP5 from Fairphone may well receive a recently updated of FairphoneOS.

However /e/OS releases (containing all the “extra work” associated with the “adjusted_for_e” system apps) often lag this by about a month, see release notes https://gitlab.e.foundation/e/os/releases/-/releases search for “security fixes”. This is the potential trigger for “anti-rollback”.

Locking the bootloader causes a Factory reset.

Speculation Easy Install may regard locking as a “option” only to be handled by the wary user, idk.

Did it actually started?
I use Ubuntu 22.04 as well, but easy-installer for my FP5 does work for the reason explained by @aibd .
I do not understand how it can possibly work for you

Hello and thank you for your answer.
It looks to me like I’ve done everything right. Or what do you say?

Android-Version 13

I have no locking experience. I think your images only show what you have now.

The danger could be if your prior Fairphone OS was say at a more recent Android SPL date. Can you confirm for yourself that this is impossible ?

Please look at Fairphone Release Notes https://support.fairphone.com/hc/en-us/articles/18682800465169-Fairphone-5-OS-Release-Notes.

At this stage you have to be 100% confident that you had either

Fairphone OS version A.131

Release date: 29th Dec 2023
Security Patch Level: 5th Dec 2023


Fairphone OS version A.141

Release date: 5th Feb 2024
Security Patch Level: 5th Jan 2024

(or earlier)

on your phone before you started /e/OS install.

Often the Baseband-Version will tie with the Vendor firmware, as a form of double check, but I did not find an exact match.
