FAQ

What Gapps to flash ?
Opengapps

SafetyNet status ?
SafetyNet passes without any mods. if magsik is installed safetynet will fail so you need to hide magisk from the settings to pass again.

Updates ?
Weekly or bi-weekly

Mine showing as L1 , still didn't use Netflix so I don't know if fhd will work or not. Just make sure to use unmodified stock vendor

You need to be on stock rom (android 10) , use newer twrp > format data > wipe system,data, cache , flash ROM.

Community builds are live

About "community" builds , these are official builds hosted on arrowos servers they only miss OTA updater. After a while these builds will become "official" with the updater.

There are two variants for each device a Vanilla (no gapps) and Gapps.

Nikkgapps is no longer recommend, if you are one my previous build and flashed nikkgapps , DON'T UPDATE until you do the following

* First Backup your data
* Wipe system
* Flash your current build of the ROM
* Flash open gapps
* Reboot
* If everything is okay , dirty flash rom update. Otherwise clean flash.

Opengapps is recommended one for vanilla builds

Gapps builds should be cleaned flashed to avoid any issues only for the first time , later on you can dirty flash.

If you are coming from another ROM always clean flash.

Pretty good rom, latest AOSP Base, but it have critical bug for me, when I'm switching off the device the Android OS Not Sending Power Off Signal…
I programmed some actions with Tasker on device power off and it not working.
And it can possible lead to some data lost.

Hmm , I never used tasker before so I don't know how it work . My best advice is to try it on los18 to see if it is a rom side issue or device tree one.

Thanks for the great ROM!

The best custom rom android 11

You are all welcome

Are there any customizations in this rom?

How is the batterylife compared to stock?

Thanks. :)

Yes, a bit more than los17/18

Any idea about moisture detection sensor working on custom roms ?

Nope not available

Having issues with netflix doesn't play any content.
You might want to check this out : Post in thread '[ROM][Android 11] crDroid Android v7.1 for S9/+ [OFFICIAL/WEEKLY][EXYNOS]' https://forum.xda-developers.com/t/...-official-weekly-exynos.4209683/post-84188511

Since I'm here, thanks for the good work king1990, after the initial setup I completely forgot that I'm using a custom ROM since February, which means everything works perfectly!

Thanks a lot for this ROM, which works perfect on my starlte! Because I don't want the full gapps package, I used NikGapps-core to only install the base essentials (play store and play services), and it works OK so far.

I do have a question though: I cannot find the options to enable the "night mode" (redshift the display in the evenings). I was assuming it's a base AOSP feature, but is it LineageOS specific?

    Night mode (native aosp option) is broken on 9810 and no way to fix it atm, los has an option called livedisplay which is not shipped with this rom.

    using nikk gapps might prevent you from updating to newer version, to avoid any issue switch to opengapps which is recommended

    When coming from Alexis Rom with ElementalX-Kernel, just wipe system/dalvik/data/cache or do i have to consider anything?

    yes but if you are encrypted you need to format data.
    (your previous rom should be android 10)

    Thanks for the explanation. The feature gap can be filled with the Twilight application in the meantime.


    Opengapps.org does not publish an Android 11 package yet, and installing the Android 10 one failed (don't recall the error message though), this is why I went with nikk gapps. Is there a Android 11 opengapps package available, that I missed?

    you can find it here
    to switch to opengapps without clean flash do the following:
    • backup first to be safe.
    • wipe system , cache , flash rom , flash opengapps , reboot
    • if everything is working you can update to newer version , otherwise clean flash.
