I've just pushed the 0004 RC1 images.
The most important thing to know (copied from the release notes draft)
is the following:

Since we use WordPress for the blog system, it's not easy to share
- By default users need an account to see the drafts. The result of it
is that none of the drafts end up being public.
- When the drafts are published they are not draft anymore.
In addition to that the default web interface forces people wanting to
While the code is probably fully free software it's still an issue to
force people to run specific code.
So we will probably have to find another way to work on announcements in
In the meantime I've written a script to semi-manually extract the
release notes from WordPress. The script has already been sent as a
patch to the mailing list, and the result has been pasted at the end of
I've also found a bug between after tagging the release, and a
patch (modem: workaround silence not finding the SIM card when it is
"launched") has already been sent for it.

# Replicant 6.0 0004 release and Replicant 9 status.
Posted on [January 9, 2020] by [GNUtoo]
Replicant is in the [list of distributions that are recommended by the
FSF.] As such, Replicant needs to follow [strict criteria] that
ensure that the distribution does its best not to violates its users’
However fixing the issues and making new releases can sometime take a
long time. The last Replicant 6.0 release was from December 2017.
This new release fixes some very serious freedom and privacy issues:
* We found an issue within the phone application: it was leaking the
phone numbers of both inbound and outbound calls to third parties
as part of a feature called phone lookup providers. More details
are available in the [bug report]. Even if it was not trivial to
reproduce and find the bug it’s now fixed as the feature has been
completely disabled with 3 patches ([], [], []).
* F-Droid has been removed as many applications shipped in it are not
compliant with the [guidelines] for distributions recommended by
the FSF. It was kept so long because we expected to get it fixed
upstream fast enough, but that didn’t happen for various reasons.
We have setup a [wiki page] and a [forum section] for more
information about the issue and how to deal with it.
* Several nonfree firmwares related to the back and home “touch”
buttons were found and removed with 4 patches ([],
[], [],[ ]). The firmwares seem to have only
been used for factory testing, so the buttons should still work on
the devices that have them.
* On all the currently supported devices with a modem, when users set
the device in flight mode, the modem is only asked to go in low
power mode. Because of that the modem is probably still on and its
OS is probably still running. Because of that we fixed the wiki and
added [the scripts to disable (and enable back) the modem] to
the new Replicant images. They work by preventing Replicant to load
the modem OS.
This release may also fix [several bug(s) which made some SIM cards not
recognizable by Replicant 6.0]: we have now merged a fix for one of
the bug ([#1909]) but as we don’t know if all the “SIM card not
recognized” bugs are related. We would highly appreciate if those that
opened the original bug report could confirm if it also fixes their
issues as well.
Several issues still need to be fixed, but we didn’t want to delay even
more this release, as that would prevent users from getting the fixes
* It’s still not possible to build Replicant 6.0 from a [distribution
that is recommended by the FSF] (bug [#1861])
* While investigating if it was possible to upgrade WebView, the
Android builtin web browser component (bug [#1786]) we also
discovered that, because Android build system doesn’t use a package
manager, finding the license of each repository wasn’t trivial (bug
* More investigations are needed as well to replace WebView with a
free software and up to date implementation (bug [#1786]).
* The bug related to a bad sound quality during calls in some
circumstances (bug [#1773]) is not fixed yet, but there is a
workaround that works for some use cases.
It will also not be possible to keep the data partition and a full re-
installation will be necessary. Users are advised to backup the
important data from the applications (contacts, SMS, etc) before
migrating to a this release. There are already [some tips] on how
to backup some applications. We didn’t have enough time to investigate
the precise cause of the issue.
As the internal WiFi doesn’t work with free software, some new network
related features improving usability were merged :
* RepWiFi has been removed as it’s now possible to use the stock
Android menus to handle the WiFi. This was done by patching Android
to also accept external dongles. It is less reliable than with
RepWiFi because in some cases reboots are needed for the WiFi to be
recognized, and enabling the WiFi most probably also powers on the
Internal WiFi chip as well, increasing the power consumption.
However it should reduce the probability of applications like
F-Droid being broken in the future, as it’s better integrated in
Android. In the event that Replicant 6.0 stops being maintained and
that Replicant 9.0 doesn’t get support for all the Replicant 6.0
devices, this patch should increase the lifetime of the affected
* Ethernet support has been added but it doesn’t work on all the
* The USB networking scripts has also been added to the devices.
* Support for some rt2500-usb dongles that don’t need the OS to load a
firmware [has been added to the Galaxy SIII 4G (i9305)], which
is an uncompleted device. Unfortunately it couldn’t be ported to
other devices in due time for this release.
Other improvements were also made:
* llvmpipe is now the default OpenGL renderer. This allows running
many applications that weren’t working before. Unfortunately
llvmpipe significantly slows down some system components used in
the graphical interface. This has been catered for by patching
Android to use the old libagl renderer for those system components.
* [Scripts to switch between OpenGL implementations globally]
have been added to the image as well. Thus, if you want to revert
back to the old behaviour, just run androidsw.sh in a root
terminal. To switch back to the new behavior you can instead use
llvmpipe.sh. Note that llvmpipe.sh will still keep the old OpenGL
implementation for the system components mentioned above, so there
is little risk in trying the scripts.
* It’s now easier to build Replicant as there is a new script that
wraps part of the building process. It’s also more convenient as it
stores build logs. The script has been used to build the release,
and the build instructions also use it now.
* It has became easier to modify the installation instructions as
they now apply to all devices, and were split into parts that are
reusable. This way a modification needs to be done only once and
not 10 or 30 times like before.
* [Instructions to backup the modem data partition] have been
added. The modem partition can [become corrupted] in some
conditions. As it can be very difficult or impossible to recreate
that partition, and that it’s required for the modem to work, we
strongly advise users to do a backup.
Work on Replicant 9 has also been ongoing in parallel. As it will use a
kernel closely based on upstream Linux, it has some implications:
* The work on Replicant 9 is made with the Galaxy SIII (i9300), so it
should be supported.
* The Galaxy Note II (N7100) is very similar to the Galaxy SIII but
requires a bit more work to be supported.
* The Galaxy SIII 4G (I9305) and Galaxy Note II 4G (N7105) could also
be added if work is done to add support for their modem in
* We don’t know yet how much work is needed to add support for the
other devices that are currently supported by Replicant 6.0, so we
don’t know yet if they will be compatible with Replicant 9 or not.
We would need to find or get more information on the upstream
status of theses devices before having a rough idea.
* It will be easier to add support for devices using a mainline
We also take advantage of this release to announce some policies
* As Replicant 6 only supports devices with isolated modems,
Replicant 9 and upward will also only support devices with isolated
* Support for devices with non-isolated modems and upstream kernel
will need to be added in other Android distributions instead.
* We are welcoming collaboration with various upstream projects and
other Android distributions to co-maintain the ability to run
Android with upstream kernels.
As Replicant 9 requires more work and working to upstream devices
support in Linux takes more time than adding devices in Replicant 6, we
also decided against supporting devices with batteries that cannot be
replaced by users and developers.
The issue is a very practical one: if we start adding support for a
device, we want to be able to spend the time required to do it right
and to work with upstream projects like Linux to add support for it in
theses projects as well. The advantage is that it makes Replicant and
the device being added more sustainable. However if the device has a
battery that is not replaceable by experienced users, developers,
repair shops, or [repair café], the device would have a very short
lifetime which is incompatible with making Replicant sustainable:
* Users would need to buy the device new in order to make sure that
the battery lasts enough for a daily use. Buying the device second
hand would be way more complicated as users would need to make sure
that the battery last enough time.
* Developers would still be able to work on the device for a very
long time, assuming that they are not users as well that want to
use the device. But their work would not be very useful without
If we look at the smartphones currently supported by Replicant 6.0:
* They all have removable batteries, so they are very easy to
* Compatible batteries are easy enough to find in several countries.
And for the tablets supported by Replicant 6.0:
* They all have batteries that are not removable in the usual
meaning, but they can still be replaced by opening the device.
* It is easy enough for experienced users, developers, repair shops,
and repair café to open the device and remove the battery, so it is
probably possible to replace it as well.
* It would be interesting to know more about the availability of
* It might also be possible to use tablets with batteries that last
way less than when the device is new, as many people have them off
most of the time. But even in that case it still shortens a lot the
lifetime of the device, as they probably still needs a working
battery to boot.
