This /e/OS 3.0.4 version includes the Android security patches available as of June 2025.
Please give the complete date in the documentation as this is important for the anti rollback feature that may brick the phone.
Example:
e/OS Version 3.04 has the patch date of 01.06.2025
Latest Fairphone OS has the patch date 05.06.2025
In this case i can not lock the bootloader as the e/OS patchdate is older than the official FairphoneOS that was installed previously.
I needed to install several tools to extract the flashfile to find this out. Please put the exact date into the documentation - would be very helpfull and cost no efford.
Thanks for the clarification. Sloppy wording on my part but I guess I was just drawing attention to the bulletin’s date of publication where I gave a recent example of the bulletin itself containing the date 01-06-2025.
It seemed to me as if Google have become more upfront about dating as many of us have got used to seeing Android SPL consistently 5th of the month until more recently.
the implicit meaning of what the OP presents is: /e/ v3.0.4 doesn’t include the vendor firmware partition updates that fairphone currently ships. Or one forgot to set the string.
I struggle with assessing how out of date (or not) /e/OS is for the different Fairphones… how would one properly assess this?
Also, one step further, if Fairphone provides security updates, it does mean all base hardware issues should be addressed, right? So as long as Fairphone still supports the device (update latency notwithstanding), the device should be patched, right?
“assessing”: SPL dates aren’t inherently wrong though intransparent. There was a CVE checker that did analysis on-device (SnoopSnitch), but I don’t think its kept updated.
“the device should be patched”: someone at /e/ has to bundle the firmware, do kernel vendor fixes, it’s not automatic
if you want to dig into it, look at the device kernel repo, firmware version strings and framework base. But it is another thread. This here is just about some help in knowing the SPL of the image offered to prevent rollback bricks.
