Ui da hast du aber ein älteres Video ausgegraben. Sollte aber denke ich noch soweit relevant sein

You need to use "pmbootstrap install" with the "--fde" flag. You cannot use prebuilt images as they can't be encrypted in-place.

As written there, Firefox does not support WebUSB, so no. You cannot use Firefox to flash postmarketOS.
You can use any other flashing method though, command line, UBports installer and so.

What if adding more printf makes less printf appear 🤔
I had that a few days ago debugging Qualcomm bootloader bits

Because Ubuntu Touch doesn't yet support Fairphone (Gen. 6).
It's just that you can use the UBports installer to install postmarketOS which is a completely different operating system.

There's no audio support at all yet, so no phone calls for sure. See https://wiki.postmarketos.org/wiki/Fairphone_(Gen._6)_(fairphone-fp6) for all the info.

Zeker langer, ik denk bij de 40km was ik al altijd ongeveer 10 uur mee bezig met pauzes, maar ik had ook nooit haast wat ook fijn is bij Nacht van de vluchteling.

The last couple of years I've always walked 40 km during Night of the Refugee (Nacht van de vluchteling). This year there is a special 50 km route, due to Stichting Vluchteling existing for 50 years. Definitely a challenge since 40 km is already quite long, but I'm confident I will succeed 😊
I'd really appreciate you donating via the link above to raise funds!

On World Refugee Day, I will be taking part in the Night of the Refugee in the Netherlands. Together with thousands of others, I will walk 50 kilometers in support of people forced to flee.
I’m raising money for emergency aid worldwide, such as clean drinking water and medical care.
Will you support me? Every contribution makes a difference. Or sign up yourself and take action too. 💛

To be honest I'm super happy not having to think about exactly what you're writing about, because other people are taking care of it (like you). Sure, kernel dev is fun but a kernel does little without functional user space!

Fairly sure [@cas](https://social.treehouse.systems/@cas ) is also aware of this, this happens on multiple Qualcomm based devices. Could also be due to some code in XBL, I wouldn't 100% blame ABL

**Update:** the UBports installer config has been merged so it should be available now with any recent version of the installer!

Some basic level of usability is there, you can see https://wiki.postmarketos.org/wiki/Fairphone_(Gen._6)_(fairphone-fp6) for the list of features that work or not work.
Most significantly audio and camera do not work at all yet.

The ADSP firmware seems to require write support via these fastrpc protocols, otherwise it just refuses to work. If you have some other ideas, feel free to try them!
For audio, some basics are already in the kernel branch, but for actual speaker support I've been working in this branch but it's not working yet with the amplifier not initializing correctly https://github.com/z3ntu/linux/tree/milos-6.19.y-wip-speaker
You'll also need something like https://github.com/z3ntu/audioreach-topology/commits/fp6/ The UCM is super basic, don't think I pushed this yet

2026-04-17 14:05:41 GMT

An easy way to install #postmarketOS on the #Fairphone (Gen. 6), with the UBports installer and the postmarketOS web flasher!
The UBports installer config is currently under review, and the postmarketOS web flasher support for Fairphone (Gen. 6) is already live at https://flash.postmarketos.org/ Enjoy!

Yep, with https://github.com/linux-msm/hexagonrpc/pull/21 it seems to be functional, but this PR will surely need some more work to be ready to be integrated into hexagonrpc.

So in short: only Fairphone 3(+) so far, Fairphone 4, 5 and Gen. 6 do not have NFC support in the kernel yet. But there now being an end-user usable way of at least reading NFC tags, there may be some more motivation now (though it's still quite low as there's way more important features that need to be worked on) :)

Front camera enablement for Fairphone 5: sent upstream ✅
https://lore.kernel.org/linux-arm-msm/[email protected]/
Vladimir Zapolskiy developed and submitted the actual S5KJN1 driver upstream (for a different device), so just some dts additions were left for me :)

Well, I'm on a camera bringup streak it seems! 🚀
As of tonight the Fairphone 3 cameras (front and rear) are working on postmarketOS with mainline Linux!
And if you saw, only last week I got the Fairphone 4 cameras to work.
A bright future is ahead for mobile Linux! 📸

Camera support on Fairphone 4 with postmarketOS is coming to you very soon!
All 3 cameras are supported, main rear camera, ultra-wide camera and front camera.
And all with a completely open source software stack of course!

Is a new fixed Synapse version to be expected today? If I read https://element.io/blog/coordinated-matrix-security-update/ correctly, it's only to be released tomorrow??

2025-06-25 09:28:26 GMT

I'm super happy to share, that the #Fairphone (Gen. 6) was just announced, and we've been able to already publish a lot of code for it!
* #postmarketOS support is submitted
* 59(!) patches were sent to bring up upstream #Linux on the SM7635 SoC and enable the device.
* The stock Android source code is public on code.fairphone.com
This has been a lot of work over the last couple of months so it's awesome to finally be able to share it!

And #Fairphone is also now finally no longer active on ex-Twitter!
Just a bit sad that Mastodon doesn't seem to be in the picture. Seems Mastodon is not a great place for corporate social media, which maybe even is a good thing to keep it more human-centered.
