Murena Fairphone 4 with OS 2.5 (A13) and Oct 2024 Sec patches, is it safe to flash now, or wait?

I have a Murena FP4 that I’ve had for about a year. I have the Nov 8 2024 OS version, which contains the Oct 5 2024 Security patches. I have not flashed an A device is YEARS… a lot has changed.

For reasons I won’t go into, I want (need) to move away from e/os. I recently learned about iode, and after some digging, it seems that this OS is in step (built in blockers, microG, etc) with what I have been using, and with a bit more flexibility. I’m comfortable in the cli, and have spent today just getting aquainted with tools, and various install methods, verifying comms, etc. My device is factory reset, so I’ve done a lot of playing without unlocking my bootloader.

One of the items I came across was that the FP4 has the Security Patch feature preventing success with a ROM with lower patches (if I understand that correctly), so I wanted to just ask:

With my phone at it’s current version, do I need to wait until a later iode release drops before I flash? And should I be able to lock the bootloader back?

Thanks!

So I thought I would post an update to this, for anyone else.

I successfully flashed the latest iode build from here (FP4 · master · ota / release · GitLab) using the iode GitLab doc. It worked with only a small “questionable moment”… more like a long pause (in which I pulled the cable and floundered for a few seconds.) But I ran through it a second time, with no issues.

I then flashed back to the e/os with this “Install /e/OS on a Fairphone FP4 - “FP4”” document (which worked to perfection actually)

I then flashed back to iode again.

I only have two questions at the moment, and it’s based on this image and a link I found in the community. I was hoping someone might clarify it, so I can install my eSim and start using this OS.

I locked my bootloader back, but still get this, with a key ID I think. I found this article that said this was normal… FP4 Relocked bootloader Futur updates - #2 by AlphaElwedritsch

In 2024, is this still normal, and do iode Fairphones show this? If not, I’m really just more curious as to the details on why/why not.

Thank you!

Yes, that’s normal an ok
