Ryuki Notes

Miui Apps Optionals

You can create /data/media/0/optionals.prop file yourself if it's not exist yet (if you are not in user 0, then change the 0 to your current user) using @mtmanager or any file manager and write any modified settings bellow inside the optionals.prop file BEFORE INSTALLING/REINSTALLING THE MODULE:

- To fix Miui Screen Recorder doesn't work with skiagl nor skiavk in some ROMs :

miui.fix.renderer=1

- If you are facing bootloop with Miui Core, you can disable public.libraries.txt patch, but you will not be able to normal install Miui apps:

miui.public=0

- To turn any Miui App Magisk Module into Global mode instead of original China mode:

miui.global=1

- To activate recents provider of Miui Home Magisk Module:

miui.recents=1

Don't use quickswitch app/module!

- If you have display brightness issue:

miui.code=0

- To show Sky feature in Miui Gallery AI:

miui.features=1

(Delete any other else miui.features)

- If there is no playback while recording with system sounds, you can change gallery mode to lavender instead of cepheus:

miui.features=lavender

(Delete any other else miui.features)

If system sound option is gone, that means your framework.jar is not supported. To check is your framework.jar support system sounds playback or not, run terminal:

su

grep -E 'createAudioRecordForLoopback|FOR_LOOPBACK' /system/framework/framework.jar

If there is no output, that means unsupported.

INSTALL/REINSTALL THE MODULE AFTERWARDS and reboot.

Global Optionals

You can create /data/media/0/optionals.prop file yourself if it's not exist yet (if you are not in user 0, then change the 0 to your current user) using @mtmanager or any file manager and write any modified settings bellow inside the optionals.prop file BEFORE INSTALLING/REINSTALLING THE MODULE:

- Some modules requires sepolicy patch to be working properly in Enforcing mode. sepolicy.rule file will be installed to sepolicy rules dir. But if there are still denials even the sepolicy.rule is installed correctly, you can use this instead:

sepolicy.sh=1

- If sepolicy patch still not enough caused by denials that are not already allowed by sepolicy patch, you can turn your device to Permissive state instead:

permissive.mode=1

PLEASE REMOVE permissive.mode=2 IF USING THIS!

This option will not be working if your kernel does not support permissive state.

- To use Magisk Permissive mode instead of device Permissive mode:

permissive.mode=2

PLEASE REMOVE permissive.mode=1 IF USING THIS!

- In some devices, using dirac & misoundfx Remover Magisk Module causes the *Parts.apk (Advanced settings app) loop crash. To fix that, you can hide the *Parts.apk:

hide.parts=1

or you can simply disable the *Parts.apk using any root disabler/freezer and reboot afterwards. Usually *Parts.apk not only contains equalizer but also contains some other ROM features. Hiding/disabling it will also remove those ROM features.

If dirac or misoundfx not working after re-enabling/removing/disabling modules, wipe dalvik cache and run:

su

rm -rf /data/system/package_cache/* /data/dalvik-cache/* /data/user*/*/com.android.settings/* /data/user*/*/com.miui.misound/* /data/user*/*/se.dirac.acs/*

Reboot.

- If you have dual speaker issue or stereo issue or earpiece issue or speaker not balanced or right and left not balanced with any of audio mods or if you want to enable auto rotation feature in Dolby Moto:

audio.rotation=1

- If you faced no sound or low sound issue on some apps while using any audio mod modules or you don't want audio mod affects your game app and notification/ringtone sound:

disable.raw=0

- You can use any modified or themed UI apk for any audio mod modules: Place the modified UI apk to your /data/media/0/ (if you are not in user 0, then change the 0 to your current user) first!

mod.ui=1

(you may need use dolby.mod=0 also in Dolby modules)

For APK UI (User Interface) modder, you can share your modded UI apk only and you have to use this feature instead. Not allowed to duplicate my modules.

- If you don't want system apps of modules keeps running in background/draining battery too much:

power.save=1

Then you can also restrict background of those apps in the app info. This option may reduce applications performance or even makes crash because some apps requires running in background to be working properly.

- To clear all data of a module:

data.cleanup=1

(After installing with that, the value 1 will be changed automatically to 0)

INSTALL/REINSTALL THE MODULE AFTERWARDS and reboot.

Global Troubleshootings: https://t.me/androidryukimodsdiscussions/29836

Global Troubleshootings

- For HyperOS users, please read here: https://t.me/androidryukimods/2218

- "Unable to find pre init dir" means you haven't completed the Magisk installation yet and the early/pre init mount will not be working in Magisk Delta/Kitsune Mask. But if you sure it's not then use #global_optionals sepolicy.sh=1 instead. But if it's showing in recovery, then it's normal.

- If module installation is freezing, probably your ROM doesn't have a complete toolbox, then you need to install busybox first: https://github.com/Magisk-Modules-Repo/busybox-ndk/blob/master/update.json (Go to the zipUrl link)

- All system apps from module will not be allowed to network access by default in some Android 13 and above ROMs. You need to manually allow it in the app info.

- Notifications cannot be turned off? If you just have disabled your Android Signature Verification, then that's the cause. But in Android 12 and up, you can't disable platform_app type notifications. You can minimize it instead. The notifications of system_app type and persistent app type also cannot be disabled in any Android version.

- Just in case if using multiple (2 or more) audio mod Magisk modules, you must install Audio Modification Library Ryuki Mod (AML) Magisk Module: https://github.com/reiryuki/Audio-Modification-Library-Ryuki-Mod-Magisk-Module (use with the latest #magiskdelta is recommended). You can also use the official AML version but with some limitations.

- If using 2 or more audio mods with different soundfx type, read here also: https://t.me/androidryukimodsdiscussions/26764

- NLSound & Ainur Narsil causing some Audio Mods not to work.

- If you are using KernelSU/APatch or SuList, you have to include your launcher app & all package name from module (listed in package.txt) to the whilelist/superuser list and reboot, otherwise apps/icons will be broken https://t.me/androidryukimods/1096. But exclude your launcher app and any package name from module to Zygisk DenyList or Xposed or Riru LSPosed or Riru EdXposed or Taichi Magisk Module then reboot!

- Sometimes built-in soundfx makes audio mod doesn't work properly. AOSP soundfx Remover, dirac misoundfx Remover, & Sound Alive FX Remover Magisk Module may solve with AML.

- If app force close or shows blank only/error, try to reboot twice without reinstalling.

- If you have a playback issue like no sound or volume getting max, maybe it's caused by Mediatek ALSA audio playback https://t.me/androidryukimodsdiscussions/135457. Then you need to change ROM. Sound Enhancement, AudioFX LineageOS, & Audio Effect Deep Field also unsupported with ALSA playback.

- If you're using Island app or Work profile, disable apps that are cloned in the Island or the Work profile to prevent conflict.

- If you have deep sleep issue with official Magisk, then you need to move to #magiskdelta instead.

- If anything is not working after installing/uninstalling any Magisk module, run:

su

rm -rf /data/system/package_cache/* /data/dalvik-cache/* /data/user*/*/com.android.settings/* /data/user*/*/com.android.musicfx/*

Reboot after.

- If wired/headset is not detected, it's probably the ROM bug using deprecated android.media.AudioSystem method in Android 11 and up instead of android.media.AudioManager method. https://t.me/androidryukimodsdiscussions/85275

- If any module is turning your device to permissive state, you can turn it back your enforcing state automatically after device boot using this app: https://github.com/reiryuki/Sound-Mods-Automator.

- If you have dual speaker but the left speaker has lower sound than the right speaker, try run this on terminal:

su -c settings put system master_balance -0.5

If the right speaker has lower sound than the left speaker, change -0.5 to  0.5. If you want to revert it to the default, change it to 0.0.

One UI Optionals

You can create /data/media/0/optionals.prop file yourself if it's not exist yet (if you are not in user 0, then change the 0 to your current user) using @mtmanager or any file manager and write any modified settings bellow inside the optionals.prop file BEFORE INSTALLING/REINSTALLING THE MODULE:

- Global Optionals: https://t.me/androidryukimodsdiscussions/60861

- To fix crashing issue while you are using Samsung app ports that's not from mine with my One UI Core module:

oneui.features=0

But this option will disable some features.

- Swipe down for notification panel doesn't work except this launcher is used as recents provider. To enable recents provider (for Android 11 and up only):

oneui.recents=1

Don't use quickswitch app/module!

INSTALL/REINSTALL THE MODULE AFTERWARDS and reboot.


Troubleshootings

Frequently Asked Questions

- Which module is best?

Nothing is best. Every module is unique.

- Is the module working for my device/ROM? Which module for my device/ROM? Can I install it to my device/ROM? Is this module better than other module? Is the module support my device? What's the different between modules? Does the module compatible with my device? Can I use this module with other module? Is this module universal?

You think I have all smartphones in the world? Give it a try/find it yourself instead and tell us after. I never create module only for a specific device/ROM.

- Does the module make bootloop or brick?

DwYOR. Every system modification has risks. If you don't know what are you doing, then don't root your device. If you didn't backup your data, that is your fault.

- This module is not working for me.. Help..

Send #bug_report. Otherwise, no helps.

- What device that you are using?

Xiaomi Redmi 4A (rolex) for now.

- What module is recommended? Any suggestion?

I will recommend and suggest you to install and try all of my work one by one and find out which is the best for ya.

- When you will update the module (ETA)?

When there is an idea and I want to update the module, I will update the module. This is not official job, so there is no ETA.

- Is there any rootless?

So many at Playstore. If there isn't, ask to their corporations, not me.

- How can I make a Magisk Module?

https://topjohnwu.github.io/Magisk/guides.html

- What is this feature? How it works?

Click here google.com and type your question there. The artificial intelligence will tell you the best answers.

- Why don't you reply my question?

Don't PM me unless you follow #bug_report. Otherwise, no reply. If I don't reply even you sent the #bug_report, that means I don't know.

- Can you port this app Sir? Is it possible to port this app Sir?

Maybe yes, maybe not.

- Is there a module for 32 bit architecture? Is there a module for Android 8/8.1/9/10/11/12/12.1/13/14/15? Can it be installed for non-rooted? Is this working with enforcing? Can it be installed via Recovery without Magisk?

READ REQUIREMENTS at README.md! If there is no 64 bit only written, then it supports 32 bit. If there is no Android version written, then it's working in any Android version. If there is no Magisk only required then it can be installed without Magisk. If there is no permissive only written, then it's working in enforcing.

- Can you add/fix a feature of audio mods?

I only port the already existing soundfx from a device, not creating a new one. Any addition or fixation about soundfx is from the product itself.

- What is your favorite audio mod module?

Moto Waves

- Is it possible to update your module via Magisk/KernelSU app (add update.json support)?

Not possible because update.json doesn't support pling.com

- How do I know the audio mod works or not?

Use your ears. But in programmatically, read #global_troubleshootings.

- Does this module spoof ro.product.name or ro.product.device or ro.product.model?

I always write it at README.md descriptions if a module is spoofing anything.

- Why sometimes the apk is treated as malware/trojan/virus?

Please read #false_positive notes!

- Unzip error? Error while installing?

Make sure you are read the installation guide. Check how much your internal storage free left. Check is the zip corrupted or not. Check are you using deprecated Magisk version or not. Don't change download saving files to external storage. Try to install again.

- Why no module is loaded?

Because you are activating Magisk core-only mode.

- What Magisk version I should use?

Use any version you want.

- How to integrate the module to ROM?

I've never even build a ROM not even kernel

- After uninstalling modules, does everything role back to original state?

Yes. Except manifest.xml patch that Dolby does.

Fix Legacy External Storage Access

- To check is the app require legacy external storage access or not:

su

PKG=
UID=$(dumpsys package $PKG 2>/dev/null | grep -m 1 Id= | sed -e 's/    userId=//g' -e 's/    appId=//g')
echo $PKG
appops get $PKG
echo "UID $UID"
appops get --uid $UID

If there is LEGACY_STORAGE written, then it's require legacy external storage access.

- We need to put these 3 lines at in AndroidManifest.xml

android:requestLegacyExternalStorage="true"
  android:preserveLegacyExternalStorage="true"
  android:requestRawExternalStorageAccess="true"

- For more info: https://developer.android.com/training/data-storage/use-cases

Miui Apps Troubleshootings

- Miui Apps Optionals: https://t.me/androidryukimodsdiscussions/54012

- Global troubleshootings: https://t.me/androidryukimodsdiscussions/29836

- If you have disabled your Android Signature Verification but still find INSTALL_FAILED_SHARED_USER_INCOMPATIBLE in Miui Security installation, then just ignore it and reboot. If Miui Security app is not installed after reboot, that means you are failed to disable Android Signature Verification and you can try another method in #disable_signature notes.

- If you have density issue, probably you are using a buggy custom kernel. Just restore your default kernel.

- The notification in Miui Gallery is a notification of media scanner foreground service required for scanning photos and videos in your storages. Just long tap and minimize the notif if it's annoying.

- Miui Gallery doesn't have inbuilt video player. Use this app instead: https://play.google.com/store/apps/details?id=com.miui.videoplayer
You can find it here also: https://www.apkmirror.com/apk/xiaomi-inc/mi-video/

- You can create PDF in Miui Gallery by installing this app: https://www.apkmirror.com/apk/kingsoft-office-software-corporation-limited/mi-doc-viewer-powered-by-wps-小米文档查看器（wps定制）/

Need to grant the storage permission manually otherwise your PDF cannot be saved. Screenshot: https://t.me/androidryukimods/203. The PDF file will be saved to internal storage /MIUI/Gallery/PDF/.

- If signature test is failed in Miui Security or Screen Recorder Magisk Module, then you need to disable Android Signature Verification first. Tap here: https://t.me/androidryukimodsdiscussions/58331. You can re-enable the Android Signature Verification after those Miui apps are installed correctly. They will be keep installed and working normally. But if you want to update or reinstall those modules, you need to disable Android Signature Verifications again.

- If Miui Game Turbo and Security Scan won't be connected to network then allow System service plugin app and MIUI security components app network access in it's app info > mobile data. Find it in your Settings app and enable show system apps. You can also find it via MT Manager > Extract APK > System App > System service plugin or MIUI security components > More > Details > Data Usage > Allow network.

- If Miui Gallery or any other else app won't be connected to network then allow the network access manually in it's app info > mobile data.

- Some people were talking about privacy concern about using miui Gallery. What’s your opinion?

I don't know

Dolby Troubleshootings

- Recommended to use Kitsune Mask in Read-Only ROMs https://t.me/androidryukimodsdiscussions/100091 otherwise, Dolby module (except Magic Revision) will be turned to hwservicemanager restarts method. It may break some system services & root hides on some ROMs. If ROM does not allow hwservicemanager restarts, you will get bootloop.

Another option:

Some ROMs are not allowed to write system/vendor caused by encrypted /data. You can decrypt your /data using this: https://forum.xda-developers.com/t/deprecated-universal-dm-verity-forceencrypt-disk-quota-disabler-11-2-2020.3817389/

If it's not the problem, try this: https://forum.xda-developers.com/t/script-android-10-universal-mount-systemrw-superrw-featuring-makerw-read-write.4247311/ or https://forum.xda-developers.com/t/guide-how-to-make-your-system-rw-super-r-w-read-write-able.4258745/

Can I use Magisk OverlayFS module instead?

No. It doesn't run in pre-init whereas Dolby manifest.xml needs pre-init.

- If you have sensors issue, or Bluetooth audio issue with OPSoundTuner UI, or still facing bootloop/softbrick even your ROM is RW, then READ #dolby_optionals!

- If you have in-built Dolby in your *Parts.apk (Advanced settings app), then you may need to disable the *Parts.apk using any root disabler/freezer and reboot afterwards. Usually *Parts.apk not only contains equalizer but also contains several other ROM features. Hiding/disabling it will also remove those ROM features.

- If your early mount dir is in /cache/, then do not ever wipe your /cache. If your /cache is wiped by another reason, then you need to remove Dolby module and REBOOT FIRST, then reinstall the Dolby module.

- Sometimes Dolby needs to reboot twice to restart sensors service.

- Some Dolby are changing/spoofing your system properties. If you have issues with that, use any other else instead. No solution for this.

- To disable FX for loudspeaker in Dolby Moto, tap 'About' then tap multiple times the text/image.

- If Dolby effect is stopped working or it's only working while opening the UI, run at terminal:

su

SVCS="vendor.dolby.hardware.dms@1.0-service vendor.dolby.hardware.dms@2.0-service vendor.dolby_v3_6.hardware.dms360@2.0-service"
killall $SVCS
sleep 1
for SVC in $SVCS; do
if [ ! "$(pidof $SVC)" ]; then
$(realpath /vendor)/bin/hw/$SVC &
fi
done
sleep 1
killall com.dolby.daxservice com.dolby.atmos com.oplus.audio.effectcenter
echo done

If there is "segmentation fault" or dms service is not registered https://t.me/androidryukimodsdiscussions/112081 then read #dolby_troubleshootings_2 https://t.me/ryukinotes/10

- If your inbuilt Dolby is not working after uninstalling any Dolby Magisk module, run at terminal:

su

rm -rf /data/user*/*/*dolby* /data/vendor/dolby /data/vendor/media/dax_sqlite3.db

Reboot afterwards.

- Can a dax-default.xml be used to another Dolby?

Usually it doesn't work because the dax-default.xml depends of vendor.dolby.hardware.dms@*-service compatibility.

- Why Apple Music and Tidal app can't detect Dolby/Spatial format in my device even I have installed Dolby module?

It's different thing. Apple Music and Tidal detects AC3/AC4 Dolby format decoder support from ROM framework.jar and whether libstagefright_omx.so is loading libstagefrightdolby.so or not and not detecting Dolby soundfx. AC3/AC4 decoder can only be added via ROM building, not via Magisk module nor any script. But why AC3/AC4 while FLAC is better and even best? There is no compression in FLAC.

- To turn on/off Dolby Magic Revision, tap the top title of the UI.

- What's the difference of Dolby Atmos and Dolby Digital Plus?

They are just the name of UI. DDP and old Dolby Atmos is using DS soundfx. Newer Dolby Atmos, Moto Dolby, & Dolby Audio they are using DAP soundfx that requires ROM/device manifest.xml support.

- Smart Audio equals to dynamic profile. It doesn't mean to change profile automatically.

- No need to remove your Dolby in-built to install my Dolby modules.

- If you have zygisk issue, then uninstall Dolby, reboot, then reinstall Dolby.
