Bugs

videos recorded with the default camera do not play

Update: Install the NGCam_7.4.104-v1.8-fix.apk Once the application is installed open it take a photo close the application, this will create a folder in the SD called Gcam, inside the Gcam folder create a folder and call it Config7 and inside this place the XML file Redmi 8 GCam 7.4.104.314953318 G_Modder.xml restart the application and you're done

the only bugs that have is slow motion record not work for now

Automatic brightness does not work

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 ( use root explorer ) and reboot ..... problem solved
the necessary files are at the end of the tutorial

Steps

Note: I did the installation coming from Mui 12.EU, and there was no problem in the installation process or in the boot process

If you come from Miui12 .EU or any other GSI Rom go to step 4, if you come from the Rom stock follow the this steps

1- 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

2- Unlock the Bootloader if you have not already done it or do not know how to, follow this post: http://en.miui.com/unlock/

3- Install a custon recovery, if you dont know how to, follow this post: https://c.mi.com/thread-2850424-1-0.html

4- Make wipe only to Cache, Dalvik, System, Data and Internal SD

5- Format data,( if it doesn't format the data you will have bootloop) then Reboot into Recovery

6- Copy all the files to the phone (Havoc-OS-v4.X-20200522-Official-arm64-ab.img you can find it by unpacking the zip), Magisk,Magisk Path Fix, Permisiver, Certification Patch.zip, opengapp (recommended nano or pico)

7- Install system image to system partition (on TWRP go to install-Install image-System) .

8- Flash Permisiver v5 (on TWRP go to install selec permisver_v5.zip)

9- Resize system partition to flash opengapps (on TWRP go to Wipe-Advanced Wipe-Select System on the list-Repair or Change File System-Resize)

To Root

once you have installed an resized the system

10- Flash the Magisk path fix (on TWRP go to install selec MagiskA11_PATH_fix.zip)

11- Flash Magisk (on TWRP go to install selec Magisk-v23.0.zip)

12- Flash Opengapps

1-Flash Certification Patch

1 - Make a wipe to Cache and Dalvik

1- Reboot

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

Hey !
I have a stupid question. Do you upload the GSI ROM and the other files on a SD card or on the internal storage ? I was searching this guide on the morning but I was wondering about that...
Thanks for your answer

You can place it in either of the two, as long as you can access the storage where you placed them from the recovery

Hi, I need to know some things to help you, what ROM did you have before flashing Havoc? do you have the bootloader unlocked? When did you use My flashtool, what method did you use?

In my particular case it was not necessary to flash vbmmeta as I comment in the OP I come from Miui12.eu, but it is necessary to avoid problems whatever the ROM you have before installing Havoc is to have the latest version of TWRP and have configured a lock pattern security in ROM access and in the flashing process I didn´t have problems

Hey!
I was on the stock ROM when i started to flash HavocOs.
I unbricked my phone with the MIUnlockTool V2 and my phone's still alive.
I booted on TWRP with fastboot boot TWRP.img 'cuz I can't boot to TWRP with volume up and power...
How can I flash HavocOs in the good way ?
I have Redmi 8 3/32 like you...

Ok the first thing is that you have the bootloader unlocked, if it is that way regardless of the stock version of the rom you have when installing twrp you must install magisk to ensure that the Recovery remains fixed in this link is a tutorial on how to install it, that tutorial was made by me and approved by Xiaomi https://c.mi.com/thread-2850424-1-0.html ,
install the latest version of TWRP and as it says in the tutorial then flash magisk, once you have everything ready install miui 12.eu do not do many settings except create a blocking pattern when starting the rom this is used by TWRP to be able to decrypt the internal memory
All ready do the steps as indicated in this tutorial (If you come from Miui12 .EU or any other GSI Rom go to step 4)

If for some reason you have a problem, use MI flashtool to return to the stock rom, but make sure to use the snapdragon method, select MIflash and when opening the screen at the bottom select clean all, this will prevent you from blocking the bootloader and you can start again without problems (note when selecting clean all at the end it will give you an error for not being able to block the bootloader and the device will restart, do not worry it will restart normally without problems)

Hey!
I thought about something this afternoon : if I flash HavocOS with adb and fastboot, we also haven't any problems with TWRP installation ! But the problem is that I haven't found any wiki to do that and i won't transform my phone to a beta tester....
Thanks a lot for your help but I think i will wait until a custom rom of LineageOs or HavocOs...

Hi . I am currently running havoc is 3.12 on my device I tried multiple times to flash this ROM without any success. Is not installing open gapps a problem ? Anyways when I flash this rom without flashing the certification patch I get a no os installed warning before rebooting from orange fox recovery but when I flash the certification I no longer get this message. Etherway I am getting stuck on a bootloop . How can I solve this issue? I did all the steps correctly wiping the correct partitions and formating data . Edit I wiped cache and dalvik after the bootloop without any success .

Hey !
I had the same bug before installing the v3.12 version.
I think it goes from the Permissiver v5. I think we should flash it to have the Havoc v4.
I'll test later if I have the time to do this and I'll inform you about the possibilities.
Hope I can help.

Thanks for replying and trying to help but last night I managed to get havoc 4.1 is installed by flashing lineage first (using another guide from this category). I will try again to get havoc 4.1 working without flashing lineage as soon as posible because I am curious .

Magisk doesn't work on Android 11

Magisk doesn't work on Android 11

Finally managed to flash Magisk on Havoc 4.1 with the help of youtuberking (telegram and YouTube).

How: just flash Magisk path fix before magisk and it's good to go.
