Much stable. Games rather smooth comparing previous version. Further improvement on heat. Please suggest sound mod other than viper. Or the one you use.

Thanks for the awesome rom.

Cannot add google account

It crashes and again starts loading. Signing from play store makes the play store app craah.

I flaahed latest 3.9 zip file the open gapps nano and the magisk 20.3.

In fact the default browser is also craahing and this is first boot.

Apart from my S and S3 I’ve had Havoc on everything since, although there's been a few small glitches here and there AND the dreaded echo (which is understandable) it’s always been my daily driver but finally NO ECHO… Great work from all the devs involved over the years (y)

    Q1 I can't pass safetynet/I can't get cts profile to be valid.Now?

    Guide to pass ctsProfile

    1. Search and download MagiskHide Props Config and Busybox for Android NDK from the Download section within Magisk
    2. Download termux from the play store
    3. Reboot the device as necessary
    4. Run the following commands within termux su then props
    5.Press the keys in order on each prompt 1,f,6,23,y,y

    Q2 My Device is stuck in Booloop

    Make sure you have followed the instructions on how we install it. Make sure you are on the latest One UI either 2 or 2.1 it doesn't matter as long as you're on Q. Wipe Everything and flash the rom, gapps (flame gapps preferable), magisk if you want

    Q3 I am having problems setting up my phone on initial BOOT

    FLASH Flame GAPPS basic. It's similar with open gapps pico but with sound picker.

    Q4 Why isn't X feature there? Its there in xyz rom

    I have recently worked on this due to the quarantine situations that gave me time to work on it. I have worked alone and currently I am working on my own because everyone is busy with their own lives right now. If you have a feature request, I will not guarantee adding it because I may get busy.
    I built this ROM for personal use but since evryone is sitting at home now I thought to publish it.

    Q5 Will we be back in the next Android version?


    Q6 Will this Rom get updates?

    Yes. Regular up to some point

    Hi, is this rom compatible with the g9600? I'm new to the world of S9 roms and I'm looking for a custom one to install, but I've seen that there are so many models that I wonder which one to choose. Gave.

    Thank you guys for the work and still supporting this device... one question, is it important to install gapps nano?

    yeah it is important or else you'll get no sound picker :D:D
