[[[ 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.

Hi all. I've messed up bad. I'm not an amateur, been rooting/installing roms for several years but mistakes can be made.
I mad a big one. it's my sisters phone and I've lost her whatsapp database backup files!
I did the usual, made a twrp rom backup to the sdcard. I've been using Migrate app to backup particualr apps.
I had used mixplorer to copy the whiole whole of the whatsapp folder to the sdcard, this is where things messed.
I thought it had completed it.
I went through this rom's installing process and it called for format data, which I don't normally do as it includes the internal memory, but as I had assumed all was backed up, I did it.
After installing this rom, I went to install whatspp, run and theres no chat restore from local databases! I dont do Gdrive backups

I've tried the usual recovery apps diskdigger/undeleterapps to find the database files, but nothing. they mostly target media and docs etc.
Dr.fone doesnt work, keeps saying the phone is not rooted, although magisk is installed and running.
I havent installed anything extra on internal memory, so still have a chance to recover files so what app or pc software could find files with such extentions from internal memory? please, I'm so desperate. The chat history of hers has some very sentimental chats and I feel so so bad messing it up..First time ever.

I have now created a twrp back up of iodeOS rom and tried to restore the previous rom (lineage 17.1 by derf),
which also seems messed up as it keeps going in a boot loop. Whats going on, I'm losing my mind.
I thought maybe whatsapp could have some other backup somewhere, cluthing at straws.

please someone

    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 (Anddroid 10 only).

    Downloads : add-ons
    • phonesky-magisk.zip : Magisk module for NanoDroid patched Play Store, for those who really need to get access to their paid apps that don't work with microG. This module can be generally be deactivated when you have installed and ran once the paid apps.
      NB : you may have to wait a couple of hours after activating the module for being able to install paid apps.
    • phonesky-magiskV2.zip : compatibility for the upcoming iodéOS 2.0 based on Android 11. It can ben installed on iodéOS 1.x based on Android 10 too.
      IMPORTANT : install this module or deactivate the previous one before installing iodéOS 2.0, or you'll be caught in a bootloop.
    How did you fix the memory leak? Couldn't find a repo with the full manifest used so couldn't check myself.

    BTW: Would be great to include build instructions and full description/code used as a privacy focused ROM should be transparent and for others to improve :)

    About our sources:
    We completely agree that transparency is at the core of a privacy-oriented project and we will (no ETA) open source our code.
    We will publish them when we consider it is the good timing. We have many features that remain to be done, we have to clean up the sources, and we want our work to be more known before doing so.
    It's great to see another privacy focused rom for this device! I do have some questions though: why not use osmand (open source nav app) for maps. Also I understand that the built in ads blocker is better than a vpn based one, but how is it compared to say AdAway? And can it be deactivated (sometimes blocklists block useful sites too or result in certain apps to not function properly)?

    I'll do a backup on the weekend and check it out.
    The main reasons for the choice of Magic Earth over Osmand: it is simpler to use, and has real-time traffic information. There's not perfect choice...

    The blocker can be deactivated globally on its home page, or app by app on the report page. However, statistics are still collected. We will add a 'mute' function, to avoid statistics collection. Both (block and mute) will be able to be combined: mute but still block, unmute and unblock, ...

    Some of the main advantages of a low-level blocker like the one were're implementing:
    • there's no need to root the phone (for Adaway, root is required)
    • VPN remains free
    • the blocker is a low-level system process which cannot be killed by the Android memory management
    • it is implemented with efficiency and security in mind (c++ with RAII principle as much a possible, multi-threaded, specific sepolicy rules)
    • fine-grained control over which app may be blocked (and/or muted in a future version)
    • very accurate statistics: we can track exactly which app makes which DNS request, which app sends or receives which packet on the network, the quantity of data exchanged, source/destination, ports, ...
    • in addition to DNS blocking (equivalent to a hosts file based method like Adaway for global blocking of all apps), we can also block network packets whose source or destination IP address has recently been associated to a domain in the black list.
    • we will be able to make even more fine-grained tuning, like deciding that a domain must blocked for a given app but unblocked for another app, and many more
