INSTALLATION

- Boot into your recovery
- Wipe data, dalvik-art cache, cache
- Flash RevengeOS build
- Optional: flash FlameGApps
- Reboot
- Optional: flash MagiskCU
- Optional: flash DFE
- Optional: flash Magisk stable ONLY AFTER MagiskCU

Just wipe data, dalvik-art cache, and cache? System is not included for clean flash? I'm used to wiping system as well so I had to make sure.

just installing the latest version, testing the mic and it doesn't go well. it has very small audio volume when try to recording sound. is there any fix about this?
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] iAlcatrazZ:
greeting guys, I have a favor to ask. I'm a complete newbie to nowaday android's zips stuff and especially MIUI. I carefully read the installation instruction for cepheus, which is Mi 9, but I'm still a bit confused. According to the instruction, my device needs to be on firmware v12.0.3 which is kinda latest version, and I only need to wipe data, cache and dalvik in order to install Revenge. But according to my device's history, it was on latest MIUI version which is 12.0.4 when I unlocked it then wipe all 5 partitions (data, vendors, cache, system, dalvik) and format data using twrp latest official version for cepheus in order to flash Havoc OS and then xiaomi.eu's 12.5 build Do I have to flash the latest official firmware and MIUI or vendors for my device once again, like restore it to factory state with the exception of TWRP before I can install Revenge OS ?

Hi. I'm interested in using this ROM, but I have a question. The post only talks about installing the ROM, but how would one go about updating it when a new version releases? Is there OTA updates, do I need to redownload the ROM from xda? Is there a notification system that tells me there is a new version? Thanks!

Witct costum kernel can suggest me for this Rom?
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Giovix92:
Sad to hear. Maybe it's caused by magisk, if you have it installed.

Quantic is a great kernel, give it a shot!
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] NafiShahriar:
After using almost 10+ days,i must say,it is the most stable version.No random reboot,good battery backup with excellent performance.Although i miss anx camera and swipe to screenshot(as it capped maximum finger support at 3),this rom is soo good that i am willing to sacrifice them.

Safety Net doesn't pass for me. Do we still need to flash MagiskCU first for it to work?

Btw, a problem I experienced was being stuck at rom boot after a clean installation (hadn't updated since Nov 20). Even my nandroid full restore was. I tried format data before and after installation which worked, although I don't know the reasoning.
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] RealNBB:
No, it is a mistake caused by Magisk.

Do you mean that it's supposed to be okay, just magisk can't test it properly? I still get a cts profile mismatch failing when testing with that other app.

My magisk is hidden and package renamed. I also tried flashing the modules 'MagiskHide Props config' and Universal 'SafetyNet Fix' but they didn't make any difference.
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] hazopoulis:
I managed to fix it by changing my device's fingerprint using this module:

https://xdaforums.com/t/module-magiskhide-props-config-safetynet-prop-edits-and-more-v5-4-0.3789228/ I assume this happened because I used later google apps?

To summarize the process for anyone with the same issue if you're too bored to read through:

flash module MagiskHide Props
reboot
open terminal and run su
run props
select option 1: Edit device fingerprint
select f: Pick a certified fingerprint and then select your device
reboot

Netflix still detects something 'wrong' though.

It magically worked, I assume after a reboot/update of the app.

oh thank you. This "ANXCameraUnity_185R.SaltyIntelligentPlainsqueaker.zip" file already is the patch? - I ask because, it's not working. Every known working mod with aux camera support is not working with revengeOS on my phone. I thought it was a real magisk patch, sorry.

edit: MGC_8.1.101_A9_GVw_snap_libs.apk seems to work stable with mi 9 aux cams on RevengeOS 4.0
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] hazopoulis:
I think this is the one. I don't know how it works for others but for me it's still buggy to use anx. I managed to launch the app through some crashes and switch to video which is the one I was looking for and then the pro tab works too for photos. Photo still crashes and I need to wipe storage to be able to use the app again.

Gcam ports work fine.

[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Bubibubibibi:
Dear Friend. Your ROM is great. It is suitable for daily use. RevengeOS-4.0-R-OFFICIAL-cepheus-20201006-2242.zip

It works quickly, 455,000 points in anttu. The hotspot is working.

If you allow a few remarks:

- the aod does not move around the display and is not very bright, the pixel shift is very small.

-the color rendering of the display is very saturated like that of a Samsung.

-battery drain in stby, a lot , 15-20% in the nigt.

-the kernel does not underclock the 1 claster up to 300mHz

- no face unlock present

thank you very much for your great work!
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] kipue:
Hi, most issues could be fixed by updates, but the battery, two things to check:

- If you have AOD on, then that's for sure going to murder the battery (it does on any non MIUI rom)

- Check if you have "pocket detection" on. That will also kill the battery.

On another ROM, I would get same as you, 15-30% drain/night, after turning both those off, I get 0-1% drain/night.

The impact of those is huge.

Hello, how AoD looks like in this ROM? Can it show notification icons? And is fingerprint unlock working with AoD?
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Thom2804:
AOD does show icons for your notifications, it supports to display currently playing media, like spotify or youtube, it does display do not disturb icon, fingerprint scanner can be accessed straight from AOD.

Sadly can't take screenshots of an AOD screen, otherwise would have showed it.
[Xiaomi Mi 9 ROMs, Kernels, Recoveries, & Other Dev] Giovix92:
EdXposed may not be compatible yet. Kindly check its github page (if any) or XDA thread.

Glad you solved! :)

Hello, can you send a log? You can pick it by going thru advanced - copy logs. :)

Hello, thank you!

Sadly, face unlock won't be added in RevengeOS, unless we find an OSS solution, in order to avoid any kind of DMCA.

Regarding the color saturation, under settings - display there's an option in order to regulate colors. Did you try that?

Talking about the kernel, I'll refer it to Ayrton (Quantic Kernel creator). :)

Thank you for your feedback! I'm gonna investigate what causes the high drain. Probably an elevated use of the ultrasonic sensor.

Hello! FOD works correctly with AOD, and it can shows notifications too! :)

Looks like any other AOD. Don't know how to make a screenshot of it though.

Is there anyway to flash magisk and keep encryption on? Btw, thanks, it's a great rom!

Edit: I figured it out. You can use adb-sideload to flash the zip through adb (as TWRP can't acces the encrypted internal storage). I had to boot without root, reboot to TWRP, flash "magisk-debug (2).zip" (cleaned cache and dalvik, not sure if necessary), reboot to system, reboot again to TWRP, flash latest Magisk Cannary ("magisk-debug.zip" from TopJohnWu's github) and wiped dalvik and cache again. Now it seems alright.

We can probably use this method for updating the rom too (usb-otg should work fine too probably)

I sure hope TWRP developers fix the issue soon, it's a pain not to have access to the internal storage from the recovery and I don't like leaving my phone unencrypted.

Is this kernel that comes preinstalled with RevengeOS same as "Quantic-Illusion-Cepheus-051020 - R" or is it some kind of custom version of "Quantic-Illusion-Cepheus-051020 - R" for RevengeOS. I am asking this becaus preinstalled kernel has gpu clock of 675mhz but "Quantic-Illusion-Cepheus-051020 - R" supposedly has 750mhz so its not the same.

Have you pay with gpay succesfully in a shop?, because I can add a credit card without problems, but can't pay. There is a "no set up" text above the card, and in contactless setup it says "phone doesn't meet security requirements"

I'm already trying to work on a fix. Sadly I don't have much time due to university, tryna doing my best. :)

Had to revert that commit in order to allow it booting without any problem. Ayrton also suggested me to NOT add it in order to not mess with lower frequencies. :)

Use magisk debug, reboot to system, install magisk 21 thru magisk manager, reboot. :)

Yep, I can pay with it! Make sure you've enabled magisk hide.
