I am attempting to install CalyxOS on my Fairphone 4 (switching from DivestOS due to EOL). However on the CalyxOS installation site the relevant CalyxOS image (link) is missing (same for FP5). Anyone know what happened or where to find the image?
According to the CalyxOS chatroom:
All Models with version 0.0.0 has current a security update problem, do it was “disabled” to download them: Install CalyxOS
If you install the current stock version, the current official calyxos version behind the security patches. So the bootloader would not let boot calyxos (because that would be a downgrade and become less secure).
Best you ask CalyxOS directly they e.g. have a Telegram Channel as far as I know, however it seems you already found the answer.
From the above quote, it appears that the Calyx team is doing this because Fairphone lags behind on security updates. Given that the most recent update came out on 27 January the next Fairphone update is likely end of March so CalyxOS won’t be available for Fairphone until April.
This makes two of the best non-google OSes - Calyx and Graphene - unavailable for the Fairphone purely because of their lagging security updates.
The other way round I would say
Well and thats wrong,
GrapheneOS is only and solely available 8n Pixel Phones and for other safety reasons and not SPL updates.
I was also taking into account this quote from the calyx install page:
Security Updates: The Fairphone 4, 5 … stock OS follows a different security update release schedule, which usually lags behind by a month or two compared to Pixels. The CalyxOS releases for it only contain the latest fixes to the open source components, such as the OS code and the Linux kernel. Proprietary components such as the bootloader, modem firmware, and other firmware get updates as soon as the stock OS update is available.
But schedules and patches aside, it’s a shame that CalyxOS is not currently available for FP, and looks like a new patch from FP won’t be until late March, and a new release from Calyx will also not be for at least a month.
My understanding was that the reason GrapheneOS is not available for Fairphones is at least partly due to the security update schedule. In this very extensive (and a little combative) reddit comment literally the first line is:
Fairphone 4 doesn’t provide proper privacy/security patches, which is the most bare minimum requirement for a device.
We are talking here in your topic about the fact that at the moment downloads are unavailable because at the moment CalyxOS is behind with SPL and not what usually is the case compared to Pixel.
So you just have to wait a few days I guess until Calyx publishes a new download with same or greater SPL
So generel update speed of Fairphones to be discussed here instead
New images are out now!
