The update worked great on the second try, no problems so far.

Unfortunately, I still had TWRP as recovery at the first attempt. Bad idea. For the repair I needed Odin and a lot of time ...

This might sound crazy. Is it possible to install micro Gapps on this Rom? Would it work with the Adblocker? I'm thinking about trying it later today.

Has anybody managed to get ANY swipe keyboard to work? I can install whichever keyboard I like - I can only type, but not swipe.

Just want to say thank you, this ROM really reduced all the efforts to get a google-free and slim ROM on the phone.

The only think left now is some TTS-Engine... (I'm currently going with eSpeak-NG)...

I managed to finally restore my WhatsApp messages. If you have a spare device handy it helps, I'll assume in my instructions that you do and this device has WhatsApp with all your data on.

On the spare device:
  • Open WhatsApp -> Settings -> Chats -> Chat Backup
  • Make sure "Back up to Google Drive" is set to "Never"
  • Then click "Back Up"
  • This will then save a local backup to the root of your device (well the main user folder)
  • Navigate to your root/user folder and compress the WhatsApp folder. It should contain 3 folders within it: Backups, Databases, Media.
  • Download Airdroid (or something similar, but this worked best for me) and start a web session.
On the new device with iodé:
  • Go to the Local IP Address displayed in Airdroid (or equivalent)
  • Download the .zip file you created.
  • Unzip this file into the root/user folder that you found it on the spare device.
  • DOUBLE CHECK: That the folder structure is the same as on the spare device:
    • Root/User
      • WhatsApp
        • Backups
        • Databases
        • Media
  • Install WhatsApp from the Aurora Store (or whereever you prefer)
  • You should then be prompted to "Restore Backup" after the SMS/Phone verification in the process.
Hope this helps!

p.s. Use Signal rather than WhatsApp if you're interested in even more privacy. The hard part is getting others to use it.
Thanks for writing this out, was enough to convince me to switch over from lineageOS with gapps.

The only things I did differently was using the USB OTG adapter that came with my s10+ and plugging it into the spare phone. This way I didnt have to compress the file (which would have taken a while because spare phone is fairly old).

I also ended up pasting the whatsapp folder in 0/media/com.whatsapp/ because that's where it was on the old phone, which worked for me

Does the proximity sensor work on your S10e properly?
My display tends to activate several times during longer phone calls. My ear then likes to activate the airplane mode ;-)
I saw the same bug report in the LOS 18.1 thread
I use the latest update(09-2021)

Which apps do not work for you?
For me there are only 3 from the Aurora Store:
1)LED Me Know and all other apps that use status notifications via the Camera LED - is probably a LineageOS problem.
2)Bolt App: Scooter app crashes frequently, Taxi app works fine(shared app, switching inside the app).
3)SpainTravel Health: official app from Spain for entry by airplain, the last 6.step is not completed, but alternatively there is still a website.

The rest works fine, even Google Maps and Banking Apps.

I tried the new update, until now everything works fine. Some lineage fixes are included. For example the fingerprint sensor of the power button does not wake the device after activating standby.
I do not like the new start splash screen, it is to bright.

I've updated to 2.2 using OTA and can confirm it worked flawlessly for my S10.
There were two issues:
  • Updated stucked at "99%" (almost finished) and device did not reboot. I had to manually reboot it, but afterwards it completed the installation and everyhting worked fine
  • Root got lost (but I already guessed this)
Update: OK, it looks as if root itself caused the issues (addon.d could not access encrypted /data). For the next run, I'll go with Lygisk instead of Magisk.

    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).

    Great Rom, I am using it since 2 hours.

    One important note:
    Your installation guide has some mistakes(at least for unlocked phones )

    You do not tell which recovery should be used. Also that you need the recovery image and the file vbmeta .img.
    The TWRP xda page instructions for Heimdall Linux helped me:

    Just a quick heads up - TWRP will break stuff just like on my lineage, lineage recovery should be added to installation instructions instead.
    Manually flashing a disabled vbmeta image also isn't needed unless AVB was disabled in this build.

    • phonesky-magiskV2.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.
