Redmi Note 4 (mido) 2019-20 - Xiaomi Redmi Note 4 Guides, News, & Discussion

Redmi note 4 (Snapdragon) aka Mido, is a beautiful smartphone with great features from a very good 4100mAh Li-Polymer battery to Hi-Res Audio support and much more. But to experience it's real and completely unbound performance,a custom software need to be flashed as OEM's software is coded with nothing but prohibitions that help boost the battery and don't know what at the cost of features we must have. In this thread, everything is explained to make most of this device except the procedures of unlocking bootloader/rooting/flashing custom recovery etc. Better get basics done first!​
So let's Start.
Best Pie Rom Available: DotOs Roms
Why= Fully Stable with amazing battery life & native Gcam with no Root solution added. Purely Stock with a very-very nice UI. Can surely be used a daily driver Rom!
Link= https://sourceforge.net/projects/dotos-downloads/files/dotp/mido/​
Decorating the System software with addons​
:::::Addons::::
Audio Mods (For Enhanced Audio Output)​
1. Dolby Atmos (No Ports available for Pie as on today/full compatibility with Nougat)
2. Dolby Digital Plus (Ports Available. Google it/lots of helpful videos available on YouTube)
3. Viper4android (Detailed below)
4. Ainur Sauron (don't think you need this on top of V4a)
5. Ainur James DSP (V4a has it all)
5. Maxx Audio (Never tried on Pie nor interested to)
6. DTS (causes system crash/random reboots/kernel specific/not something to cry for)​
::::Flashing Viper for Android (v4a) in Pie::::
Previously, I had to go to the download section of Magisk to dowload and flash this audio MOD systemlessly(the beauty of Magisk). That is still convenient but since Team DeWitt's Viper App has come, the process of flashing v4a has become so easy as installing a regular apk. Really, its way better now. But as promised, both the ways are detailed below?​
1. Flash using Magisk Dowload section.
For this, just touch into Magisk's Download section> search or scroll to Viper for Android>install> and then hit reboot>Done! V4a Installed!
2. Install as a normal apk>authenticate popup for installing driver>hit reboot> Done! V4a installed!​
"Experiencing Dolby's Objective Audio Technology alongside Viper For Android"
Requirements:​1. Any custom Nougat ROM
2. Latest Magisk Installed!
3. Dolby Atmos
4. Viper For Android (App)
4. Internet connection (for downloading Audio Modification Library from Magisk)
Installation/Procedures
Follow serially>>
1. Rename downloaded Dolby Atmos zip to "axon">Open Magisk Manager>modules>Touch add icon>navigate to Dolby Atmos(axon) zip downloaded earlier>Select and follow the instructions.
2. Install V4a as apk downloaded earlier> install driver>grant super user access prompt>exit on done.
3. Open Magisk Manager>Downloads>search Audio Compatibility Patch> install. (for audio apps like Spotify etc. to process Audio Mod effects)
4. Now again in Magisk Manager>downloads>serach AML>download>install>reboot!
(If device automatically reboots after installing V4a driver, repeat step 3 & 4 and reboot again.
Thats for Now! Like If you Like!
Will be back with more on this device.
Please do not request a feature. I'm not a developer but a superuser.

As far as I believe Arise doesn't work with 8.1 (could be wrong) But I use a magisk Module Viper4Magisk or whatever it's called will install V4A works fine I tried a Dolby Oreo zip on the Arise thread but it didn't show in app drawer so not sure if that installed correctly hope that helps :good:
Fwiw, I used this with Magisk 15.2 in a clean install of 8.1. Working without issue

It doesn't actually give you dual speakers though? My understanding is that one side is a speaker and the other is a microphone.

How do you get Viper to work? Which prompts are the correct ones? After installing 2.5 with everything else it gives me an I/O error on installing the driver. I'm on LineageOS 15.2 btw.

First of all are you on aml viper? ARISE doesn't work with 8.1 and i'm talking to some of the devs about fixing this issue. I've had some experience with LOS, it may be throwing an error because of the rom or because there are some other things LOS has by default that is interfering with viper. The builds are unstable, my advice would be to switch to crDroid because it is LOS based, but is made for audio. I'm not sure what you mean by prompts but I have been hitting the vol up key both times and it works for me on the Pixel Dust rom

I changed the v4a guide, you don't need the permissive module, maybe that's what's crashing it?

It didn't "crash" per se, it just wouldn't install the necessary driver after the package was installed. I'll try it with the module disabled and see if it works. Do I still need the permissive module for the other mods? Or just when they're being installed?

Viper4Android Pixel 2 XL stereo speaker optimization profile (Android Q working)

Updated: OP contains instructions for Android Pie and below, post #5 has current instructions for Android Q.
Saw a couple Viper4Android threads, did not see much in terms of profiles for the 2 XL specifically. Just got the 2 XL coming from a 6P and there was a great profile to optimize it's internal speakers so decided to try out the mod for the 2 XL's speakers. Working very nicely.
Not sure if this will work with every ROM but works nice on Bootleggers (should work on any Pie ROM including stock) and thought I would share so more people could enjoy much improved sound quality. Makes rooting the phone well worth it.
Instructions:
After installing Magisk 18.1
Install BusyBox and run the set-up
Download the Viper4Android V4.1 (used Material theme) via Magisk manager
run the install process, select 2.5.0.4 material theme, install as system app, grand root access then reboot
Load the DorianX profile taken from the 6P. Just unzip then look over the extracted files.
Edited to explain further: You will probably need to individually place the "SRS Audio HD" IRS file in the Viper4Android Kernel folder and put the Profile folder in the Viper4Android Profile folder (using a file explorer to copy/paste the files). Once that's done, in the Viper4Android app under "Convolver", tap it and choose "impulse response file", You should see the "SRS Audio HD" IRS file that you placed in the Kernel folder, select it, tick the box next to Convolver to enable it. Under the main app settings you should be able to select and load the profile. If you did it correctly the DorianX profile folder should be visible to select it. It depends which version of Viper4Android you install. If you do materialized (2.5.0.4) the above should work. Let me know if any problems
Play some music. Toggle Viper4Android master power on and off under the phone speaker tab within the app then back to on once to enable it. Usually you have to do this to "officially" enable Viper4Android. If it's working you will hear the difference. Under the app settings you can verify that the app is processing as well under "driver status". Working with the latest Poweramp, Youtube, etc.
Credit to DorianX who made the profile. There are 4 profiles included to optimize specific bluetooth devices, headphones,etc but just using the internal speaker one (for now). Unable to locate the past post in the 6P forum containing the profile and which other devices were optimized to link to it.
Works very well and thought it was worth posting and making a small contribution so for now enjoy! Profile attached.
Have Viper4Android working nicely on Android Q Beta 4.
Those that downloaded this profile if you don't mind posting the Dorian profile speaker settings (all of them for each tab and whether enabled or disabled) would appreciate it. Profiles no longer can be loaded in this version of Viper.
Looking at the speaker xml file can see some of the settings but probably not all.
Magisk 19.3, Adaway works, viper now works all on today's beta 4. Tried all versions and combos. Getting the driver to install and stick was a big pain.Can post some instructions if anyone is interested. I'm sure plenty of people would like to get viper working.
Now if only Google apps like Gmail and Google play would be themed. Can see the force dark toggle is broken in this beta. Not sure if the Google apps were theming in Beta 3 or not.

See below
Ok I got it. No need to PM me the profile. Took most of the night but done now.
Would be unable to stay on Q without Viper4Android as well...
Make sure to uninstall all previous versions of Magisk and modules to start fresh.
Install Magisk 19.3 via twrp, install latest Magisk manager and then Busybox (make sure to set up busybox). Some are having problems with this Beta and Magisk so YMMV. Working well for me and no app lag.
On Pie in Magisk you should see Viper4Android 2.7.1 module as available
On Q it's not listed (for me at least) so get it from XDA labs.
Install Viper4Android:
https://labs.xda-developers.com/store/app/download/com.pittvandewitt.viperfx (link to direct download, must be signed in)
Or use this link: https://labs.xda-developers.com/store/app/com.pittvandewitt.viperfx
The installer will install it as a magisk module. Grant supersu permissions, install driver, phone will reboot.
Install the magisk audio modifications library module. Reboot. After rebooting disable this module (do not uninstall). Reboot again.
Open up Viper4Android. If it asks you to install driver again do so and phone will automatically reboot. Repeat if needed. If driver install remains unsuccessful try enabling and disabling the audio modifications module then try again. What worked for some worked the opposite for others in past threads on previous Android versions and various devices. Here is the thread for reference: https://forum.xda-developers.com/pixel-2/help/viper4android-driver-installation-fails-t3766362
Once driver is installed the app will load properly and under driver status it will probably say "unsupported" and "abnormal". Close the app
Go back into Magisk manager. Now toggle to re enable the audio modifications module. Reboot. (This is the module that allows Viper4Android to process and can help to install the driver)
Upon reboot, Viper4Android should work. Play some music, check the driver status to verify, you may need to toggle off/on master limiter to finally enable it.
For this profile, put the SRS file in OP above in the Viper4Android Kernel folder. Under the apps speaker tab manually input these settings:
Master limiter: On
Playback gain: moderate or 2, max gain 4x, output threshold -1.9db
FIR Equalizer: On. EQ is flat
Convolver: On. Tap convolver then select the SRS inpulse file you placed in the Kernel folder. Cross channel set to 0
Profit.
You can set or disable the viper4android notification icon in the statusbar within the app's settings.
Let me know how the 2 XL's speakers sound Post updated, instructions should be clear enough. Some having problems will need to wait for the updated Magisk. Moving forward, we do have viper4android working on Q. Fully tested on my 2xl and stable with beta 4.
Thanks to @Team_DeWitt
And Dorianx for his profile originally created for the 6p

Playback gain: moderate or 2, max gain 4x, output threshold -1.9db
FIR Equalizer: On. EQ is flat
Convolver: On. Tap convolver then select the SRS inpulse file you placed in the Kernel folder. Cross channel set to 0
Profit.
You can set or disable the viper4android notification icon in the statusbar within the app's settings.
Let me know how the 2 XL's speakers sound Post updated, instructions should be clear enough. Some having problems will need to wait for the updated Magisk. Moving forward, we do have viper4android working on Q. Fully tested on my 2xl and stable with beta 4.

succesfuly, ty
for my 2xl It was
1. installation from xda lab - reboot
2. install audio modification library - reboot
3. open viper (still asking to install driver - just close app, don't choose nothing)
4. go to Magisk switch off audio modification library - reboot
5. viper successfully load, status normal and working (media) with just my favorite profile no custom settings

Our 2 XL's can be temperamental, lol.
Glad you got it working. Not sure how the driver installed and the viper app fixed itself with the audio modifications module switched off. It's like you didn't need that module at all. Whatever works.
Just happy we have viper for Q. Played games, music, youtube and running stable here.

Ok I got it. No need to PM me the profile. Took most of the night but done now.
Would be unable to stay on Q without Viper4Android as well...
Make sure to uninstall all previous versions of Magisk and modules to start fresh.
Install Magisk 19.3 via twrp, install latest Magisk manager and then Busybox (make sure to set up busybox). Some are having problems with this Beta and Magisk so YMMV. Working well for me and no app lag.
On Pie in Magisk you should see Viper4Android 2.7.1 module as available
On Q it's not listed (for me at least) so get it from XDA labs.
Install Viper4Android:
https://labs.xda-developers.com/store/app/download/com.pittvandewitt.viperfx (link to direct download, must be signed in)
Or use this link: https://labs.xda-developers.com/store/app/com.pittvandewitt.viperfx
The installer will install it as a magisk module. Grant supersu permissions, install driver, phone will reboot.
Install the magisk audio modifications library module. Reboot. After rebooting disable this module (do not uninstall). Reboot again.
Open up Viper4Android. If it asks you to install driver again do so and phone will automatically reboot. Repeat if needed. If driver install remains unsuccessful try enabling and disabling the audio modifications module then try again. What worked for some worked the opposite for others in past threads on previous Android versions and various devices. Here is the thread for reference: https://forum.xda-developers.com/pixel-2/help/viper4android-driver-installation-fails-t3766362
Once driver is installed the app will load properly and under driver status it will probably say "unsupported" and "abnormal". Close the app
Go back into Magisk manager. Now toggle to re enable the audio modifications module. Reboot. (This is the module that allows Viper4Android to process and can help to install the driver)
Upon reboot, Viper4Android should work. Play some music, check the driver status to verify, you may need to toggle off/on master limiter to finally enable it.

Good stuff. To anyone else installing viper just to note if you click on driver and see it as processing = no this does not mean you did anything or the install went wrong. Play a video or music, driver should show as processing yes. When nothing is playing then processing will be no.
Does this enable dual speaker for calls/message alerts?
How did you guys get magisk working on Q beta 4? For me it makes systemui not start on boot and it skips the lock screen entirely. And if it does boot normally, apps take over 10 seconds to launch. I have tried to wipe system data cache and then ran the flash-all bat and still have the issue. A lot of others have the issue on the magisk canary thread. Some don't have it. Someone suggested after a full wipe with -w it fixed it.

Looks like I found a solution that is working for several members (and it was purely by accident because installing Magisk threw an error). Uninstall Magisk in TWRP first then:

It's not working for me. I had to reboot about 4 times because systemui wasn't starting up and I was getting a black wallpaper with no status or nav bar. Finally rebooted normally and at times apps refuse to open but it's slightly better than it was. This is just so weird. Do I really need to wipe my phone or is it magisks fault?

Someone in the Android Q discussion thread might be able to help better. Google pulled the beta so it's tough to say whether in your case it's a magisk or android issue. Or both.
I love this post for real, I have a Pixel 3 with Android P, viper v2.7.1.
I had to port the userprofile to the new version, if someone want it, PM me

Feel free to post it as well. Curious how you were able to port the profile. Looked everywhere but couldn't find any info to convert the old profile to the new preset format.

Yes it did the same for me. The first time, almost forgot. I did not find the sound to be the same, not even close. Ultimately I still had my Nexus 6p and was able to retrieve the settings and input them manually. Then the sound was as it should be.
Do you find the sound identical with the ported profiles? It might be hit and miss.
