i was using a older version and have yesterday installed the 'iode-3.1-20220726-cepheus.zip'. Now the phone won't boot into os. Only into recovery. I can not mount anything as it can not find the cryppto footer and can't mount data. I want to restore the twrp backup but it is not there. How do i get my old system back?
I had the same issue but have now managed to restore my previous version (1.5) by using the Wipe/Format Data option in TWRP before pushing & installing the old v1.5 zip (I also had trouble doing that initially).

However I still haven't worked out how to install v3.0 or above. Could there be a similar issue to on this thread or is that just specific to Samsung? I am still on TWRP v3.4.0.0-mauronofrio. Do I need to upgrade this too before/after moving to iode v3?

For all of those having trouble installing version 3:I mentioned in the OP that it requires a clean flash due to an incompatibility in the encryption method. Do not try to dirty flash: it cannot work.

ROM is nice but how can i install the play store?
And what is about Face ID? Not yet implemented or it will be never?
Actually this Rom is made for more privacy, so all Google play stuff and so on are removed due thie reason.
But if you realy urgent need some app from Play Store try out " Aurora "as alternative.
Not all Apps will work when MicroG is not enough google for them ;-)

Update 20th feb 2023
Always do a backup of your signal account before updating or changing your system, or changing your phone, or you may lost your account.


Hello, I had a problem with Signal private messenger when transfering my account, because of the "human verification", it can't do it on Idodé Os. I've read somewhere that Signal was using googleplay at know.
Does someone know a moded version of Signal that I can install on iodé os without problem ?

This is a great ROM!

Smart Charging is working perfect with USB but not with wireless charging? Is there something one can do to get it running?

Appreciate iodéOS since a few years now and proud to use it as an occitan ;-)

However I have the latest (3.5) version on my MI9 (non rooted) but the new version of applications available on F-Droid can't be updated because a signature mismatch with the older version.

How can this problem be solved?

    iodéOS is a privacy-focused operating system powered by LineageOS and based on the Android mobile platform. iodéOS aims at protecting the user's privacy with a built-in adblocker and by freeing the smartphone from snitches.

    The objectives in the conception of this ROM are threefold:

    1. To keep the stability and security level of LineageOS, by minimizing the modifications made to the system. Apart the system modifications required by the adblocker, we mainly only added a few useful options commonly found in other custom ROMs, made some cosmetic changes, modified a few default settings to prevent data leaks to Google servers.
    2. To ease a quick adoption of this ROM by new users. We especially target users that are concerned by the protection of their privacy, but are not reluctant to still use inquisitive apps like Google ones. We thus included MicroG as well as a coherent set of default apps, and simplified the initial setup of the system. Particularly, an initialization of MicroG has been made with GCM notifications allowed by default, a privacy-friendly network location provider (DéjàVu) pre-selected, as well as Nominatim Geocoder.
    3. To provide a new and powerful way of blocking ads, malwares, data leaks of all kinds to many intrusive servers. We are developing an analyzer, tightly integrated into the system, that captures all DNS requests and network traffic, as well as a user interface (the iodé app). Compared to some other well-known adblockers, this has the advantages of:
      • Avoiding to lock the VPN for that use. You can even use another adblocker that uses VPN technology alongside our blocker.
      • Being independent of the kind of DNS server used by the system or set by an independent app: classical DNS on UDP port 53 or any other one, DNS over TLS (DoT), DNS over HTTPS (DoH), ..., as we capture the DNS requests before they are transmitted to the system function that emits the DNS request. What we do not support, is DoH when it is natively built into applications, i.e. when an app communicates directly with a DoH server, without asking name resolution to the system. It would require to decrypt HTTPS packets between such an app and the DoH server, which may create a big security hole.
      • Precisely mapping DNS requests and network packets to the Android apps that emitted (or received) them.
      • Deciding which apps have a filtered network usage (by default, all apps), and which ones can communicate with blacklisted servers.
      Since its first versions, we added many features to the iodé blocker: several levels of protection, fine-grained control over the hosts that should be blocked or authorized, displaying statistics on a map to see the quantity of data exchanged to which countries, clearing statistics... We are actively developing the blocker, and new functionalities will be regularly added.


    Changes in LineageOS to prevent data leaks:

    • Default DNS server: Google's DNS replaced by Quad9's 'unblocked' servers in all parts of the system.
    • A-GPS: patches to avoid leaking personnal information like IMSI to supl server.
    • Captive portal login: connectivitycheck.gstatic.com replaced by captiveportal.kuketz.de for connectivity check.
    • Dialer: Google default option replaced by OpenStreetMap for phone number lookup.

    Pre-installed apps:

    We included many useful default apps, but our choice cannot suit everyone; so we added the possibility to remove them. It can be done at the end of the phone setup, or at any time by going to Parameters -> Apps & Notifications -> Preinstalled apps.

    • MicroG core apps: GmsCore, GsfProxy, FakeStore.
    • NLP backends for MicroG : DejaVuNLPBackend (default), MozillaNLPBackend, AppleNLPBackend, RadioCellsNLPBackend, Nominatim Geocoder.
    • App stores : FDroid (with F-Droid Privileged Extension) and Aurora Store.
    • Browser: our own fork of Firefox (with Qwant as default search engine, many other ones added, telemetry disabled, parts of telemetry code removed) instead of Lineage’s default browser Jelly.
    • SMS: QKSMS instead of Lineage's default SMS app.
    • Email: p≡p (Pretty Easy Privacy).
    • Camera: our own fork of Open Camera, with a few tweaks.
    • Maps/navigation: Magic Earth GPS & Navigation (the only one free but not open source).
    • Keyboard: OpenBoard instead of AOSP keyboard.
    • PDF: Pdf Viewer Plus.
    • Personnal notes: Carnet.
    • {Ad/Malware/Data leak}-blocker: iodé.
    • News: to keep users informed about our developments, as well as a FAQ.
    • Meteo: Geometric Weather.

    Pre-included FDroid repository:

    The apps that we tweak or develop (microG services, the browser based on Firefox, the News app, Open Camera ...) are available through a repository that we included in FDroid (check the "Apps for iodéOS" category). For this purpose and to avoid name conflicts of some apps, we also had to make a few changes in FDroid.

    Useful options from other custom ROMs:
    • Smart charging (disables charging when a given level is reached, to protect battery health).
    • Fingerprint vibration toggle.
    • Swipe down to clear all in recent apps (Android 10 only).

    • 07/02/2023 (build 20230131):
      • Blocker:
        • Improved blocking settings. You can now choose 'Standard' blocking (ads, trackers, malwares, etc) or 'Reinforced' blocking (same objective but more extensive), and then select additional categories.
        • The 'Porn' category has been extended to a wider 'Sensitive content' one, that also includes fake news, gambling, drugs, piracy, torrent..., with mainly child protection in mind.
        • The 'Extreme' category has been removed, as it is now part of the reinforced blocking.
        • Improved blocking lists. We merge several acknowledged and up-to-date sources, and have diversified our sources to produce more complete lists. The standard list has however been reduced a bit, to avoid as much as possible interference with apps expected behavior.
      • Added a new network location provider: Local NLP Backend. It is an improved version of the DéjàVu NLP backend which was already available in iodéOS. Like DéjàVu, it builds a local database connecting localizations learned from other NLP backends and apps using GPS, and mobile antennas/Wifi; but also has an active mode (not preselected) that can trigger GPS requests. To configure it: Settings -> System -> microG -> Location modules
