[Android General] ivelischt:
CooperTUGA, thanks for writing. And I want to apologize for letting you wait for so long. In fact, at the moment i do not actively develop this ROM (due to data loss on my virtual machine). :(

Anyways, i will try to address your issues as good as i can, though i must admit, none of these issues happened on my device.

ad 1: The only thing that comes to my mind is, that something went wrong when registering your device with the Android-ID. (see OP activation instructions). The SafetyNet-API itself should be working, atleast I had no similar issues (after Registering the device it takes some time - around 5 minutes - for Android to reflect the registered state).

But if someone happened to have this issue and knows another solution, you are welcome to tell! :)

ad 2: Does it help when you try to import the Files from the SIM card? As for Google contacts, it is - from my POV - stringent, that, if the SafetyNet API doesn't work properly, you will be unable to access Google Services (as Google Contacts) which would explain the missing Google Contacts.

ad 3: GApps and microG are two different things. GApps install a version (open-source fork, contains proprietary binaries) of the Official Google Apps, that is, they provide full functionality towards google services, provided you registered your device correctly.

microG is a pure Open Source fork of that, providing but the Framework with which Google Apps can be run. It does not provide Google Apps (like PlayStore etc.) by itself but merely allows them to run, given the configuration is right. This microG-ROM is not built to work with GoogleApps like PlayStore, but instead relies on the microG Services to get Apps, providing same or similar services, running (like Aurora Store etc.). To address your question, it is possible, to change the source code which was used to build this ROM, so it builds with Gapps or completely free of any such services, in fact it would mean to exclude certain patches, but such projects (Treble-enabled) are covered by others and because of above stated reasons i will not be able to provide such in near future.

Short but clear: No, there is no way to "uninstall" microG as it is built together with the ROM and the source used was especially prepared to use microG. But if configured right, you should be able to use your Google-Account in combination with Google-Services-Apps or Games despite using microG.

ad 4: See above. If everything's configured right, you should be able to play Pokemon GO, although i don't use any of these Apps (Clash Royale, Pokemon GO, WhatsApp). I never encountered any Problems along using Google Apps with this ROM.

ad 5: Well, the error says it all. I have Mozilla Location Service installed, which works like a charm. Maybe try this one? You can get it from FDroid, search for "MozillaNlpBackend" and see if it helps to sort this out? This works for me, after all.

ad6: as this is very unspecific, i cannot really tell what's the problem, but i would guess it has to do with the SafetyNet API not doing what it should or even the Location Backend not reporting position in time...

Did you clean your cache and data partitions while installing this ROM? I really am not sure what could create the behaviour you describe. Maybe there was a change in the SafetyNet/Device Certification process since this ROM-Build, maybe theres someone in those boards who could answer this, but i unfortunately can't... :(

I'm sorry that i cant give you more positive news, but hopefully it helps you in orienting what some common problems could be caused by.

Let me know about your success in trying to get the ROM working.

Best regards and greetings to portugal! :)
