You wont need a video for that. Just take a Android 10 base ROM (I took the one from Alex in this section, May Version), flash it, go back to TWRP and flash iode, wipe data, done.

BEWARE: the play store magisk module given in the OP (unofficially supported) needs to be updated *before* updgrading to iodéOS 2.0 to avoid a bootloop. You can find the updated version in the OP.

Do i have to install the NanoDroid's magisk module before flashing the iode? currently i flashed iode and twrp directly replacing stock rom and not installed magisk yet because i have to run banking app first before rooting otherwise it wouldnt work.

It must be installed after iodé and magisk. Maybe you could try your banking app with magisk hide, it may work.

My compliments to you and the entire iodé team. I just updated my S9 from iodé 1.2 to iodé 2.0 using the integrated updater. The download and installation went extremely smooth and there was no need to recover any backup data that I had created before (just to take no chances ;)). I only had to re-install Magisk v23.0 afterwards.

Great job (y)& thanks a lot.

    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 (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.
    • Email: p≡p (Pretty Easy Privacy)
    • 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, ...) 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).

    [[[ Breaking News: iodéOS 2.0 in beta testing phase ]]]

    We're proud to announce that iodéOS 2.0, based on Android 11/LineageOS 18.1, is in beta testing phase (and runs pretty well).
    If you want to join the beta testing team, follow the link in the News App (FAQ, About Iodé, How can I contribute).

    BEWARE: the play store magisk module given in the OP (unofficially supported) needs to be updated *before* updgrading to iodéOS 2.0 to avoid a bootloop. You can find the updated version in the OP.
    Do I need to change some settings to take it in effect?
    Not at all! If anything, if you want; that is, you can enable Google Cloud Messaging, and even log in into your google account and have everything linked up. It's mostly seamless, if anything you MIGHT have to configure the UnifiedNlp for GPS, IF it's not preconfigured.

    Our beta tester volunteers can now configure the blocking level of their iodé phones!
    Feel free to join our Telegram app group (link in the news app) if you wish to become a beta tester.
    I'd love to, but I can't find the telegram link anywhere, nor is it on the OP.
