No sorry. Only used miui for a few weeks 1/2 year ago then switched to RR.
Switched to Luis kernel for RR 5.8.4 and it is running very well. Best kernel so far.

Posted V15 of the init script. See OP.

Which RR are you using? Doesn't Luis' RR comes with Luis kernel?:highfive:
Also I noticed your audio tweaks, do you have any idea how to reverse right and left audio channel? If there is such a line that governs that? Thanks in advance
@snkmv Still RR 5.8.4 Firmware 35 and Luis kernel 
I assume you want headphone L/R channel switch?
You can try this in /etc/mixer_paths_sku1.xml
<path name="headphones">
<ctl name="MI2S_RX Channels" value="Two" />
<ctl name="RX1 MIX1 INP1" value="RX1" />
<ctl name="RX2 MIX1 INP1" value="RX2" />
<path name="headphones">
<ctl name="MI2S_RX Channels" value="Two" />
<ctl name="RX1 MIX1 INP1" value="RX2" />
<ctl name="RX2 MIX1 INP1" value="RX1" />
Maybe?

That works, thank you, somehow the audio feels off though compared to when I just switched L/R earphones, so hard to explain, but thank you still
Figured maybe just my ear, understandable when I was wearing the earphones the wrong way

into <ctl name="RDAC2 MUX" value="RX1" />
Just play a little with these values. Keep an original copy of the xml file in case you mess up. Nothing can go wrong. Just try

rootless camera features tweaks
From phone in recovery it does not find /etc/device_features/santoni.xml, while with phone turned on i can copy and edit it on my pc... Is there a rootless solution? For camera2 api someone managed how to copy, edit on pc and save build.prop through adb and it worked for me also, but this time i can't reach santoni.xml (in mycase is whyred.xml) in recovery mode
Hi,do you know if there is any way to edit santoni.xml with adb fastboot without enabling root permissions?

Thx very much for replying! actually I have Redmi note 5 and instead of santoni.xml i have /system/etc/device_features/whyred.xml
There is no /sdcars/device_features/ path in /system/ or parent folder... I'm able to modify the file through adb pull, notepad++ and then adb push (followed by adb shell chmod 644 /system/etc/device_features/whyred.xml)... The editing is confirmed as if i newlly pull the file on my pc, i can recognize the added lines (and also comments i added)
But the edited version doesn't exist while the phone is turned on (if i use adb pull it returns the original file and i receive a permission denied message)
If i newly turn off the phone, the edited version appears again... Can you find an effective way to edit permanently the whyred.xml file (your santoni.xml)
I would like to not enable root access with magisk as i said before
Thank you very much for help!

Reversing Stereo output on earphones
guys i need help regarding reversing stereo output on my earphones, i.e. left sound to right and right sound to left.
My Device : Redmi Note 4X (mido) (rooted with Magisk)
ROM - MIUI 9.1.3 by Xiaomi.eu on Android v7.0
i attached the screenshot of mixer_paths_qrd_....xml files for more info of files on my system.
i tried altering values as told by @tweakradje in ___qrdhf.xml , ___qrdh.xml , ___qrdm.xml and rebooted still doesn't worked out.
the below method doesn't work for me as my device don't have this file -> /system/etc/mixer_paths_qrd_sku1.xml

@sam_auditore Did you search with Google? I did a search and found that Note 4X uses
/system/etc/mixer_paths_mtp.xml
Could also be in /vendor/etc!
Good luck.
/system/etc/mixer_paths_mtp.xml
Could also be in /vendor/etc!
Good luck.
Very bad idea
After modifying that mixer_paths_mtp.xml file , no sound is played by my device now and even after restoring original file the sound cannot be played by system
I just changed rx1 to RX2 and vise vesa as you originally told in the previous post which i quoted.
Error generated by Poweramp player when trying to play music is shown in the attachment.

Permissions on file? How good are you with Android and linux? I gave you all I can help. You will figure it out!
This thread is for Redmi 4X. Not Note 4X!

29Hello xda world,
EDIT 24 may 2018: using Luis kernel now on RR 5.8.4. Best I have tried so far!!
Link: http://luis-builds.de/downloads/lineageos/rr/Xiaomi_Redmi_4X_(santoni)/
EDIT 10-feb-2018: battery drain due to *alarm* and *launcher* system wakelocks solved with firmware V32.
Grab it here and flash with TWRP: https://forum.xda-developers.com/xiaomi-redmi-4x/how-to/firmwares-t3682965
Here I hope to collect some tweaks and mods that work in rooted Redmi 4x stock rom. (8.2.10.0 Global)
EDIT: since I use Resurrection Remix now I also added some RR tweaks
Since I just own the device it will be work in progress for a while. I search the forums for solutions for problems I encounter.
My Redmi 4x is OEM unlocked via Xiaomi, has twrp and Magisk root. (you need root for tweaks)
For OEM unlock you need account and register at miui.com, ask for unlock, wait 30+ hours and then use the miui unlock tool that checks if you are granted bij Xiaomi for unlock.
Some Redmi 4x facts:
- Xiaomi Redmi 4x has codename Santoni
- The Soc is Qualcomm 435 (msm8940 socid 313, msm8937 for the firmware), 4 cpu cores perf and 4 cpu cores power
- The gpu is Adreno 505
- main camera is Samsung S5K3L8, front camera is Omnivision ov5675
- notification LED has RGB!
- 5 GHz (11ac) only supported for wifi hotspot (wlan.ko issue)
- MIUI features are setup in the /etc/device_features/santoni.xml file
- CPU/kernel features are mostly setup in the /etc/init.qcom.post_boot.sh file
- fastboot: hold vol- and power, release power after vibrate
- recovery: hold vol+ and vol- and power, release power after vibrate
Redmi 4x related sites:
- Official miui.com for Redmi 4x http://en.miui.com/forum-123-1.html
- Resurrection Remix ROM for Redmi 4x https://sourceforge.net/projects/resurrectionremix/files/santoni/ (Antutu score 43000+)
- Miui EU ROM https://xiaomi.eu/community/forums/miui-weekly-rom-releases.103/
- Mi-Globe ROM (like EU ROM but with options) Mi-Globe
- Miui Belarus (MiuiPro) ROM https://miuipro.by/roms/
- Redmi 4x Global Edition on Bangood
- AOSP Extended (AEX) ROM Redmi 4X http://downloads.aospextended.com/santoni/
Note: If you change any file always make a copy of it first. I always copy the file in the same folder and give it extension .ORG. So build.prop becomes build.prop.ORG with adb shell: cp -p build.prop build.prop.ORG
Be sure the permissions of the files are set to rw-r--r-- (644)!!!!!!
Example adb/linux commands
From pc:
adb push "afile" /sdcard
adb shell
On device:
su
stop
mount -o remount,rw /system
cd "/afolder"
cp -p "afile" "afile.ORG"
cp /sdcard/"afile" .
ls -l "afile*"
chmod 644 "afile"
reboot
Ofcourse afile and afolder are just example names.
If you are not familiar with linux shell or adb then you can find zip files to flash in TWRP mode.
You need to REBOOT after changing any of these files.
Note 2: I am not responsible for any damage to your device. Use this at your own risk!
Audio recording mod (mixer mod)
Recording audio on stock rom is terrible. On the internet I found a solution. You need to change 2 mixer files.
If you also want louder speaker you need to copy /etc/mixer_paths.xml too.
/etc/mixer_paths_qrd_sku1.xml
mic volume for voice call
mic volume for audio rec like movie, try between 100-124, use 100 for very loud envCode:<path name="voice-call"> <!-- tweakradje add 2 lines --> <ctl name="DEC1 Volume" value="88" /> <ctl name="DEC2 Volume" value="88" /> <ctl name="PRI_MI2S_RX_Voice Mixer CSVoice" value="1" /> <ctl name="Voice_Tx Mixer TERT_MI2S_TX_Voice" value="1" /> </path>
mic volume for audio rec like movie, try between 100-124, use 100 for very loud envCode:<path name="handset-mic"> <path name="adc1" /> <!-- tweakradje add 2 lines --> <ctl name="DEC1 Volume" value="110" /> <ctl name="DEC2 Volume" value="110" /> <ctl name="IIR1 INP1 MUX" value="DEC1" /> </path>
Code:<path name="handset-stereo-dmic-ef"> <!-- tweakradje add 2 lines --> <ctl name="DEC1 Volume" value="110" /> <ctl name="DEC2 Volume" value="110" /> <path name="speaker-dmic-endfire" /> </path>
/etc/audio_platform_info.xml
Code:<acdb_ids> <!-- tweakradje add 2 lines, but no more auto rec mic volume --> <device name="SND_DEVICE_IN_HANDSET_MIC" acdb_id="1"/> <device name="SND_DEVICE_IN_HANDSET_STEREO_DMIC" acdb_id="1"/> <device name="SND_DEVICE_OUT_SPEAKER_PROTECTED" acdb_id="136"/> <device name="SND_DEVICE_OUT_VOICE_SPEAKER_PROTECTED" acdb_id="136"/> <device name="SND_DEVICE_OUT_SPEAKER_PROTECTED_VBAT" acdb_id="136"/> <device name="SND_DEVICE_OUT_VOICE_SPEAKER_PROTECTED_VBAT" acdb_id="136"/> <device name="SND_DEVICE_IN_CAPTURE_VI_FEEDBACK" acdb_id="137"/> </acdb_ids>
Now audio is fine when recording video and sounds even great!
You can download the 2 files below. Check if you need to insert these lines in your file or that you can use mine.
For recording stereo audio only I use Sony Audio Recorder which is free and perfect.
EDIT 18 dec 2017: Found that acdb_id="4" works well, which is the default mic profile in ACDB. However you need to lower the "DEC1 Volume" and "DEC2 Volume" to 94.
EDIT 23 dec 2017: About Audio Calibration (ACDB) files
You might have noticed that there are more than one set of acdb file in /etc/acdbdata folder. There are MTP end QRD sets. QRD stands for Qualcomm Reference Design. You can play with these Calibration Profiles for speakers and microphone.
Easiest is to create a new build.prop (644) in the /vendor folder.
Then play with these values. You can also mix MTP and QRD for devices. Like using all MTP but for General and Handset use the QRD version.
Code:persist.audio.calfile0=/etc/acdbdata/QRD/QRD_Bluetooth_cal.acdb persist.audio.calfile1=/etc/acdbdata/QRD/QRD_General_cal.acdb persist.audio.calfile2=/etc/acdbdata/QRD/QRD_Global_cal.acdb persist.audio.calfile3=/etc/acdbdata/QRD/QRD_Handset_cal.acdb persist.audio.calfile4=/etc/acdbdata/QRD/QRD_Hdmi_cal.acdb persist.audio.calfile5=/etc/acdbdata/QRD/QRD_Headset_cal.acdb persist.audio.calfile6=/etc/acdbdata/QRD/QRD_Speaker_cal.acdb #persist.audio.calfile0=/etc/acdbdata/MTP/MTP_Bluetooth_cal.acdb #persist.audio.calfile1=/etc/acdbdata/MTP/MTP_General_cal.acdb #persist.audio.calfile2=/etc/acdbdata/MTP/MTP_Global_cal.acdb #persist.audio.calfile3=/etc/acdbdata/MTP/MTP_Handset_cal.acdb #persist.audio.calfile4=/etc/acdbdata/MTP/MTP_Hdmi_cal.acdb #persist.audio.calfile5=/etc/acdbdata/MTP/MTP_Headset_cal.acdb #persist.audio.calfile6=/etc/acdbdata/MTP/MTP_Speaker_cal.acdb
MIUI Camera mod (features unlock)
This is how you unlock those high end features you find on higher end models. To enable the features you need to edit the /etc/device_features/santoni.xml (or /sdcard/device_features/santoni.xml) file. Mostly change false into true to enable them.
Some are also added from other Xiaomi devices.
Download from below.
Camera parameters found:
Code:support_camera_4k_quality support_camera_age_detection support_camera_aohdr support_camera_audio_focus support_camera_boost_brightness support_camera_burst_shoot support_camera_gradienter support_camera_hfr support_camera_manual_function support_camera_movie_solid support_camera_peaking_mf !support_camera_press_down_capture support_camera_quick_snap support_camera_record_location support_camera_shader_effect support_camera_skin_beauty support_camera_tilt_shift support_camera_torch_capture support_camera_ubifocus support_camera_video_pause support_camera_water_mark
Camera 2 API
You can enable Camera 2 API for 3rd party camera apps. Think about manual focus etc.
Add this line to your build.prop:
persist.camera.HAL3.enabled=1

Better (modded) MIUI Camera
From my friends at 4pda. Much better camera at low light. Also JPEG quality set to 98.
http://4pda.ru/forum/index.php?showtopic=793497&view=findpost&p=57013739
Flash zip in twrp (backup of original camera is made by script)
If you want to do it manualy:
- take the MiuiCamera.apk from the zip
- adb push MiuiCamera.apk /sdcard/
- adb shell
- su
- mount -o remount,rw /system
- cd /system/priv-app/MiuiCamera
- mv MiuiCamera.apk MiuiCamera.apk.ORG
- mv oat oat.ORG
- cp /sdcard/MiuiCamera.apk .
- chmod 644 MiuiCamera.apk
- ls -l
- stop
- sync
- reboot
Enable Dalvik JIT (Android 6)
Add this line to your build.prop file:
debug.usejit=true
When cleaning the dalvik cache your phone will boot much faster. Don't have to wait for 5 or 10 minutes anymore
Test Color Notification Led
See here: http://en.miui.com/thread-605570-1-1.html

Change MIUI theme and launcher
You can change variables of the package (apk) using MIUI themes. But you can also change the default theme.
The default theme is located at /system/media/theme/default
Changes to the MIUI Launcher (home screen) can easily made. It is a zip file (com.miui.home.zip) with a theme_values.xml in it. Change or add values to the xml file, copy it to /system/media/theme/default/com.miui.home and reboot.
Note that the zip has no extension when you copy it to the folder!!! It must have the name of the package.
Below you find an example of a 5x6 launcher grid. If you want to know more better search google with MIUI_Theme_Values
You can do this for example also with MiuiSystemUI.apk (com.android.systemui) and many more
Alternative CPU core control
There are 4 performance cpu's (cpu 0123) and 4 powersave cpu's (cpu 4567). Depending on the task load they increase or decrease their cpu frequency. But they can also switch on or off. Default 2 perf cores and all 4 power cores stay on.
I modified the /etc/init.qcom.post_boot.sh script for the purpose that only 1 perf and 1 power core stay on with no task load. This consumes less power and increases battery life.
Copy init.qcom.post_boot.sh.txt to /etc/init.qcom.post_boot.sh and reboot. Don't forget to make a copy.
Code:echo 1 > /sys/devices/system/cpu/cpu0/core_ctl/min_cpus ### power cluster min 1 cpu max 4, busy up/down from 0000 to 68 and 40, perf cluster up like 80+ ### prefer (low-)power cores cpu4567 up before perf cores cpu0123 (high power consumtion) echo "80 85 90 95" > /sys/devices/system/cpu/cpu0/core_ctl/busy_up_thres #68, only looks at 1st value echo 68 > /sys/devices/system/cpu/cpu4/core_ctl/busy_up_thres echo 40 > /sys/devices/system/cpu/cpu4/core_ctl/busy_down_thres ### Wait x ms before switching core off, you might need it again echo 500 > /sys/devices/system/cpu/cpu0/core_ctl/offline_delay_ms #100 (test .5 sec) echo 500 > /sys/devices/system/cpu/cpu4/core_ctl/offline_delay_ms #100 (test .5 sec)
Resurrection Remix strange adb shell prompt
Change /etc/mkshrc, comment last 3 lines

My additions to build.prop (/vendor/build.prop)
This is my current /vendor/build.prop and the big advantage is that you can leave your ROM's /system/build.prop as it is. The /vendor/build.prop will overwrite settings from /system/build.prop!

If you have more interesting mods don't hesitate to post them and I will add them to the OP.
EDIT 5 sep 2017: added new RR init script (v2), better CPU cores and audio !!! v2 might cause battery drain, then v3
EDIT 8 sep 2017: added /etc/wifi/WCNSS_qcom_cfg.ini for 40 Mhz channel on 2.4Ghz
added new RR init script (v3) for better battery life
EDIT 15 oct 2017: removed mixer_paths.xml, use stock. Changes applied to new mixer_paths_qrd_sku1.xml
EDIT 21 oct 2017: added V4 for RR, better target_loads for big/little CPU's
EDIT 31 oct 2017: added V5 for RR, better big perf/little lowpower cpu switching. Perf cpu minimal is 0. Most tasks done with lowpower cpu's. Can run youtube for almost 11 hours now!
EDIT 4 nov 2017: Noticed one little error in V5 RR script.
Echo Y > /sys/module/workqueue/parameters/power_efficient
should be
echo Y > /sys/module/workqueue/parameters/power_efficient
EDIT 16 nov 2017: V6 RR script. Optimal use of RAM. Tested for 3 GB only. All apps stay in ram. Almost no swapping. Example, Chrome keep tabs without reloading. Antutu score now 46350!
EDIT 20 nov 2017: V7 RR script. Create 512 MB ZRAM swap if RAM < 2GB and don't lower swappiness (only for 3 GB)
Little change for V7 script:
### tweakradje use small cores to the max before switch to big cores (antutu only 35000 instead of 46000)
echo 0 > /dev/cpuctl/cpu.upmigrate_discourage
EDIT 23 nov 2017: added stereo recording in AAC with Redmi 4X (speakers cyburg needles with Tangband w3-881sjf https://www.youtube.com/watch?v=MsgAFoTghvw )
EDIT 2 dec 2017: little corrections in V7 RR script and changed to flashable zip.
EDIT 6 jan 2018: change emmc max freq from 200 to 300 MHz. Increase the read speed from 80Mb/s to 120 Mb/s (note: you can try 400 or 500 Mhz. Might cause reboot, please report back) Test with busybox hdparm -tT /dev/block/mmcblk0p49
EDIT 13 feb 2018: V9 of the script. Added tweaked deviceidle (doze) settings. Device looses 0-1% overnight!
EDIT 15 feb 2018: V10 of the script. Improved Light/Deep Doze settings with documentation in the script. Put your email app in the whitelist too!!!
EDIT 18 feb 2018: V11 ready. Won battle with Google Play Services that reset the device_idle_constants to "null" every few hours. Solution: pm disable --user 0 com.google.android.gms/.phenotype.service.sync.PhenotypeConfigurator
Doze settings and explanation are in the script for those who want to change some timings. The script sets it to this scheme:
- Enter light doze after screen off
- Light maintenance windows every 5 minutes
- Enter Deep doze after 15 minutes (enter deep if there is no alarm within 5 minutes from now, was 1 hour)
- Deep maintenance windows every hour
- Whatsapp and Gmail white listed (can do their thing regardless of doze state)
- No delays for phone motion or whatever
EDIT 8 mar 2018: updated some audio related files with comments in it. Change to your liking, now awesome high quality good calibrated stereo sound recording!!
EDIT 6 apr 2018: V13 of the init script. Changed things like min/max cpu speed for custom kernel
EDIT 9 apr 2018: flashable scripts now create backup of replaced files if not exist. (*.ORG)
EDIT 25 may 2018: V15 of the init script for 7.x Nougat ROMs.
EDIT 16 jun 2018: V16 of the init script for 7.x Nougat ROMs (LAST AND FINAL!)
Cheers11PLEASE don't quote first post. Waste of space and it will change anyway. THANKS
Data partition is encrypted
I found that the data partition is encrypted when coming from Miui ROM to RR. Fingerprint is not working with encrypted data partition.
Data is encrypted if TWRP asks for unlock code.
These steps decrypts it and preserves data.
Code:- Boot into TWRP - Backup /data to "internal sd" (or to "ext sd card") with TWRP - On PC: adb pull /data/media/0 - Wipe -> Format /data in TWRP - Reboot to TWRP again - On PC: adb push . /data/media/0 - On PC: adb shell chown -R media_rw.media_rw /data/media/0 - Reboot to TWRP again - Restore the previous backup with TWRP - On PC: adb shell rm /data/system/locksettings* /data/system/*.key - On PC: adb shell rm -r /data/dalvik* - Reboot
Change Doze (deviceidle) settings
On the device you can change the Doze settings very easy. First list the Doze settings to get all current parameters:
Code:dumpsys deviceidle
Then change parameters by setting some variables in the Android Global Settings db:
Code:settings put global Phenotype_flags device_idle_constants settings put global device_idle_constants inactive_to=300000,idle_after_inactive_to=300000
Enable light doze too (mLightEnabled=true mDeepEnabled=true)
Code:dumpsys deviceidle enable all
Add whatsapp and gmail to the whitelist
Code:dumpsys deviceidle whitelist +com.whatsapp +com.google.android.gm
Note: Google Play Services reset the device_idle_constants to "null" every few hours. Solution: pm disable --user 0 com.google.android.gms/.phenotype.service.sync.PhenotypeConfigurator
See more info in post above
Use Fingerprint sensor as button
As you might know hardware keys have keycodes. These keycodes can be found using an app like KeyEvent Dipslay
The mapping between Keycode and Function is done in the kl files in the folder /system/usr/keylayout
To map the Fingerprint key (Keycode 353) you use the gf3208.kl file.
Code:#key 353 ENTER #key 353 CAMERA #key 353 MENU key 353 SLEEP
Reboot for effect. This will not effect the Fingerprint function.
Super audio for Resurrection Remix
To enable HD audio for headphones and other audio tweaks for RR (maybe for Miui too)
Add these lines to the end of your build.prop

Some tweaks for camera driver
To enable some extra features to play with. You can add these to the end of your build.prop
For the stock camera on RR ROM make sure you disable Color Denoise setting.

More will follow4I will repost V7 with cpu.upmigrate_discourage = 0
I think V7 of the script is the best. At least for my 3GB RAM Redmi 4X. I get 46000+ Antutu and got 11,5 hours SOT when used continiously whatching youtube in a test run.
Again thanks for your feedback.3The V7 script in the zip file in the OP already has that commented out!
Code:# check actual charging current : cat /sys/class/power_supply/battery/input_current_now # USB charging little higher, fully charge in 2 hours echo 0 > /sys/class/power_supply/battery/restricted_charging # Charge 0nly up to 89% instead of 100% for longer battery life? cat /sys/class/power_supply/battery/voltage_now #echo 4260 > /sys/class/power_supply/battery/voltage_max # 4400 (nominal 3.85V) #echo 4380 > /sys/class/power_supply/battery/voltage_max # 99% #echo 2000000 > /sys/class/power_supply/battery/input_current_max echo 2000000 > /sys/class/power_supply/battery/constant_charge_current_max #cat /sys/class/power_supply/battery/charge_type -> should be Fast or Taper
Happy New Year everybody! Best wishes and Heath for 2018!3V9 of the script. Added tweaked deviceidle (doze) settings. Device looses only 0-1% overnight!
