Great ROM, much better better battery life and performances than miui plus the tracking blocker is a big plus.

However i would like to update the rom to the latest version but the updater tells me that no updates are available. Is there a way to fix the problem or do i need to flash it again ?

Thanks for the great work.

Cannot open Whatsapp links (wa.me and api.whatsapp.com) from browser.
When I try to start a Whatsapp Chat via the web browser (same problem on Iode and others) by entering wa.me/(telephonenumber), Whatsapp doesn't open (error message "Whatsapp not installed").
Of course I installed it and in it's settings the links wa.me and api.whatsapp.com are pointing to the app.
Anyone any idea?

P.S. Reinstalling Whatsapp didn't help and the same thing for Telegram (t.me/....) works to open the app.

It looks really promising ROM and very nice mindset.
Could you please publish a procedure for building this ROM,
So more developers could help with supporting more devices and increase the community.
As well this will contribute to the transparency of this solution and for the trust in this solution.

Thank you for this very nice ROM! I like privacy!

I tried to use the smart charging with my wireless charger. Unfortunatly the phone didn`t stop charging at the 80 percent that i selected. Is there a fix?

I had the same smart charging issue with HAVOC. So i installed "Battery Charger Limit" from F-Dorid. This worked. But the device has to rooted. Is there a easy(!) way to root this device in this ROM ot to install Magisk?

Hey Vincent thank you for the sources I appreciate it very much. Unfortunately I could not build it with the provided informations either. I am not very experienced and also want to ask you for further build advices for this rom.

thank you and have a nice day

Do iode recommend any VPN, and cloud services?
should i wait until you provide us with something in the next updates 😁?
Thank you so much .
We are planning to add VPN/cloud services to our solution by the end of 2021 but certainly not for the next update which will come in the following days. Can't recommend you any particular for now

    iodéOS is a privacy-focused operating system powered by LineageOS and based on the Android 10 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 (all open source, with one exception), 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.
      The iodé blocker is already perfectly usable, although still in its infancy. Many features are lacking, like the possibility of clearing statistics (for specific apps or all), forbidding the collection of statistics for some apps, personalizing the blacklist, etc. We are actively developing it, 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.
    • A-GPS: supl.google.com replaced by supl.vodafone.com.
    • 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:
    • MicroG core apps: GmsCore, GsfProxy, FakeStore, maps API.
    • NLP backends for MicroG : DejaVuNLPBackend (default), MozillaNLPBackend, AppleNLPBackend, RadioCellsNLPBackend, NominatimNLPBackend.
    • App stores : FDroid (with F-Droid Privileged Extension) and Aurora Store.
    • Browser: our own fork of Firefox (with Qwant as default search engine and telemetry disabled) instead of Lineage’s default browser Jelly.
    • SMS: QKSMS instead of Lineage's default SMS app.
    • 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.

    Pre-included FDroid repository:

    The apps that we tweak or develop (microG services, the browser based on Firefox, the iodé blocker app, the News app, ...) 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.

    === New Update : 07/03/2021 ===

    Available as OTA (see OP)​
    Looks like you're good at guessing what kind of ROM I might like before even I know what I want :D

    I picked my Mi9 half a year ago because it appeared as the best available piece of hardware (among the devices with a chance to open the bootlader and hope for a future with a well-maintained custom-ROM).
    I might not have done so if I had not found your ROM beforehand, hoping it would proof to be good enough until official Lineage-Support might start sometime soon...

    I was honetly suprised by its quality and reliable updates. I loved its focus on microg and privacy from the start and since around May I'm no longer intending to drop it in favour of 'official Lineage'.

    Two days ago I wanted to check for updates in its thread and got shortly shocked when reading "This rom will be discontinued in its current form."
    Seconds later I started to smile again and that smile grew bigger while reading about your ambitious plan and the shape it has already taken.

    I downloaded and dirty-flashed it straight away and from that beginning on I am completely happy in terms of quality/stability. The added features are a perfect continuation on your previously chosen route.

    In short: I love it and I'll keep coming back for more! :laugh:

    Btw.: Where are the right places for donations?

    Thanks a lot for your words! glad you like it :)

    For donations... Just to be clear and transparent, Vincent and I recently launched 'iodé' as a french startup selling refurbished smartphones with iodéOS rom. I will add a paypal link via xda where you can donate if you wish, but I wanted to clarify this
    Thanks for your comment!

    About stability/reliability, we are very cautious with the additions we make to lineage. We don't want to make a ROM with tons of options that may begin to be unstable, or cannot be upgraded with OTAs. This principle of stability and reliable updates are at the basis of Lineage, and we stick to that. Our focus on privacy do not require heavy modifications of Lineage's sources and Android system, except a small part for supporting the adblocker, but this cannot affect reliability of updates.

    As mentioned by Antoine (@iodeOS), we're launching a start-up to sell refurbished smartphones with iodeOS pre-installed. This startup in some sense, will sponsorize the development of this ROM that will also be freely available ; so if you want to help us, you can sponsorize iodeOS via its paypal link... And by the way, many thanks for the 3 ad-free months you offered us :)
    It must also be considered that the two aspects of that project (the startup and the iodeOS ROM) are in some sense disconnected: even if we do not succeed in the startup, we will continue to develop the ROM, just for passion and personal interest for our own phones ;)

    Hi, it seems the device tree on GitLab is private. Could you make it public?
