I have two issues:
1. GPS reception is very, very bad
in the NON-GApps variant and in the GApps variant. I already tried to change the gps.conf, but I couldn't get any improvement. I can't get a signal interior and it takes 10-20min to get a very weak signal outdoors. I'm checking the status with the App Satstats (fdroid)
2. No SMS (in the NON-GApps)
in the NON-GApps variant I'm not receiving any textmessages (SMS)
Can anybody help to fix these issues! Actually I like the ROM very much, but missing these two functions make it unusable for me...
Here I bring to you the official Havoc-os ROM for ARM64 A/B devices and fully functional on Redmi 8
The intention of this post is to make a step-by-step tutorial on the installation of this excellent GSI ROM on Redmi 8 and give assistance in the installation process
All the development credits for this wonderful ROM go to the Havoc team

What is working:
Everything works perfectly
Automatic brightness is not working, (brightness must be adjusted manual for now)
Update to fix the automatic brightness on your device, after installing the ROM, put in the folder SYSTEM-OVERLAY the treble-overlay-xiaomi-redmi 8.apk and set the permission for the apk on 644 and reboot ..... problem solved
the necessary files are at the end of the tutorial
Remember I am not a developer if you are presenting any bugs let us know and you can contact the Havoc team at the links described above
I am not responsible for any damage caused to your device by not following the steps or negligence at the time of this process, All the steps were carried out and tested on my personal device and are confirmed, My device Redmi 8 3/32 global version, the version that i tested Havoc-OS-v3.5-20200522-Official-arm64-ab.img.xz
First make a backup of all the necessary information in case something goes wrong you can easily recover,Charge the battery at least 80%
All your data will be deleted during the process
the necessary files are at the end of the tutorial
1) Unlock the Bootloader if you have not already done it or do not know how to, follow this post:http://en.miui.com/unlock/
2) Install a custon recovery and flash vbmeta.img together
Note: TWRP is recommended for this process but you should be aware that depending on your type of screen there may be problems (TWRP work fine on Tianma display), so you can also use Orange fox,
Note2: it is recommended not to use Hyper Shell for the installation of vbmeta.img it can cause problems, cmd can be used in the root folder plattform tools
Note3: If you already have the recovery installed and you are only going to flash vbmeta.img it is recommended to redo the full TWRP installation process together at vbmeta.img, restart in the recovery you can see that the encryption of the data is no longer available if you had it, and then boot in the ROM (in my particular case I did not do it first time and then could not put the files necessary for the installation in the internal memory)
Note4: use only This conmand to flash vbmeta.img " fastboot flash vbmeta vbmeta.img" if you disable the secure boot loader with the Disable_Dm-Verity command then when starting in the ROM you will not be able to configure any lock or passsword for your devices.
3)Format data, if it doesn't format the data you will have bootloop
4)Make wipe only to cache, dalvik, system, data
5) Copy all the files to the phone (Havoc-OS-v3.5-20200522-Official-arm64-ab.img you can find it by unpacking the zip, permisiverv5, magisk,Certification Patch.zip, opengapp recommended nano or pico)
6) Install system image to system partition.
7) Install permissiver V5
8) Resize system partition to flash opengapps.
9) Flash Opengapps
10) Flash Certification Patch
12) Install Magisk (optional if you want rooted your ROM)
the boot process takes 5 to 10 minutes the first boot in case of any problem in any of the stages you can reinstall Miui version fastboot with Mi flash tool and start again
How upgrade (Same Android Version)
1 Make a Wipe on Dalvik and cache only.
2 install the 3.x version system image on the system partition
3 Install permissiver V5
4 Resize system partition to flash opengapps.
5 Flash Opengapps ( if you dont flash the gapps you will have a fc on google apps )
6 Flash Certification Patch
