Introduction

Hello Friends!

I had troubles to find current builds for my devices so I decided to make regular builds for my devices. When my friends told me about similar problems, I extended the builds to include their devices as well. So these builds were and are mainly for my friends and me, but I finally decided to provide them also for public download.

My ROMs
My LuisROM an awesome combination of performance, customization, power and the most new features, brought directly to your device. The LuisROM build server generates automaticly every 2nd days new builds directly from the sources. Thanks to (thanks to @LuK1337) for the device,vendor and kernel sources.

Notice
Sometimes I get a lot of help or feature requests from users of my LuisROMs. My dog Luis and I try to fulfill most of the wishes, but that is not always possible. I do that as a little hobby and Luis does not always want to build ROMs . Please understand if I can not always answer directly.

signature spoofing permission to enable MicroG

Coming from LOS, I installed this ROM on my tablet to try out MicroG. (Great ROM btw, faster and more stable. Great work!) For MicroG, one needs signature spoofing support, which is not available in LOS, but should be built-in in the crdroid ROM, hence the switch.
Unfortunately, there seems to be something wrong with signature spoofing. When I check its status in the Signature Spoofing app, it does report back as enabled (see screenshot "Signature Spoofing check"). When I do the self-check in the MicroG app, I get the same result but MicroG doesnt seem to be getting the permission to do signature spoofing (see screenshot "Self-check MicroG", unchecked boxes). It reports : "This is a strong indicator that the ROM does support signature spoofing, but requires further action to activate it. Please check the documentation on which steps might be required."

I tried in settings, applications, permissions to give the MicroG the signature spoofing permission. The permission is there, but I can't seem to add applications to it. Also checked developer options, but couldn't find anything there, nor in a thorough search of information on signature spoofing and microg. Maybe I'm missing something really simple here, maybe it's something completely different. It just feels like I'm really close.

So I'm here to ask whether anyway knows which extra steps might be required in this ROM to give the MicroG app the permission for signature spoofing.

Any help would be greatly appreciated.

I am not familiar with MicroG but a brief search seems to indicate that it is sort of replacement for gapps and that it has a forum of its own in XDA. Have you tried checking there? It sound like an interesting concept and I'd like to learn more about it. Why is signiture spoofing needed?

I haven't tried the forum there, as the problem seems to be related to settings in the ROM, as the error message states. Ofcourse, I did some searches there and on other forums for information specific to this issue, but wasn't able to find anything useful. Which is why I tried here. I'll leave my question here for some time, giving people the time to respond. If that doesn't work out, I'll try in the other forums. But I'm afraid they'll just point be back to this forum.

About your question, MicroG is indeed a replacement for gapps, cutting you of from the all-seeing eye of Google, but without losing (too much) functionality. Privacy is why you would go for it. MicroG needs signature spoofing so that its apps can present themselves as official Google apps. You can find more info on signature spoofing here and here. More info on MicroG can be found here.

I'm in your previous ROM with Android 9.0. Can I do a dirty flash with this ROM or do you have any specific recommendations?

 

[ViktorFoedowski]

I followed you installation instructions. Got twrp installed and flashed your ROM. Now it is stuck in the boot animation for hours.
I tried flashing the ROM only. Tried with simultaneously flashing opengapps and tried with wiping data before rebooting.
All of them resulted in the same thing. Device stuck in the boot animation

 

[mperson007]

Did you format data instead of just wiping? To get out of boot loop, hold down both volume keys, insert USB cable, then press and hold down power key. It will put you into boot loader mode so you can re-flash.

BTW, when in TWRP, make sure to select ROM zip, then add OpenGapps zip, then add Majisk zip. Reboot after all 3 have been installed.

 

[ViktorFoedowski]

Yeah I stumbled over the format data. I just wiped instead of formating. Now it worked and booted succesfull.

 

[Watschnbam]

great Rom thank you !

And thank you for your Work to keep it up to date!

 

[23598685]

I had a hard time installing this rom, none of the v6.4 roms worked.
two roms failed to update vendor image, error 7
one rom failed to update system image, error 7
I have been running Luis Android 9 rom before, tried wiping, formatting, different twrp versions etc.
Updating via twrp this version worked:
crDroidAndroid-10.0-20200303-gts4lvwifi-v6.3-LuisROM-4.9.215
after booting I was able to do an online update, got version 20200316 running now.

@8224Freak Is there a way to change the quick settings icons to black? Whenever I change the accent colour to anything else than white the icons are white instead of black which looks worse than the default black. Also the rotation animation is not working.

Aww, come on, you must be able to find a smaller nit than that to pick!!

 

[fn_noobee]

Does Dex (desktop mode) work with this ROM?

 

[Sparh4wk]

Hi,

I installed this great rom.. but I just wanna be sure.. is it needed to flash your kernel as well if I want to use it, or is it already in included in this rom?
