Hi everyone! After a couple of days working on ubuntu, I have built my own kernel

If you enjoy my work, please buy me a coffee. Thanks: http://nui.pe.hu/donate.html

I AM A STUDENT, NOT A DEVELOPER. I CANNOT FIX ALL ERRORS. SO PLEASE DON'T GIVE MY APP 1 OR 2 STARS.

MOD: Disable emulated storage (internal storage)

MOD: Disable emulated storage (internal storage)

FOR ANDROID 6.0+: http://forum.xda-developers.com/showpost.php?p=63787343&postcount=845

This mod works on almost roms. I tested it on CM11, CM12, Bliss pop v2.3, AICP, CM12.1 (beta 2 and 3), Flex OS and XenonHD
Update: Maybe not works on CM12.1 nightly

Unlike init.d method, this method is more stable. It will disable the emulated storage and change default storage to your real sdcard.

To use this mod, you must have:
- A computer running Windows
- Java Runtime (jre) installed (to use apktool)
- Your xperia M using NUI kernel
- You have to move ALL data from internal storage to sdcard before using this mod
- Download this file: http://www.mediafire.com/download/rj3vnokcbl8eyit/disable_emulated_storage_20150917_2.zip

Update log:

Guide:

Extract files from disable_emulated_storage.zip
Run 1Pulling_Files.bat and follow the instructions
After running 2Patching.bat, 3 files named backup.zip, NUI_MOD.zip and NUI_MOD_1.zip are generated
Flash NUI_MOD.zip
If it doesn't work, flash NUI_MOD_1.zip
If both files don't work, flash backup.zip

Enjoy!

Notice:

If you want to remove your sdcard, turn off phone first.
Wiping dalvik cache is recommend

Pre-built file (just flash it and enjoy):

Thanks so much for this kernel!

What's the default voltage for any given CPU frequency and how much can we undervolt safely at 1.3Ghz for instance?

Not sent by me.

You can reboot your phone to have the default voltage value
This is my UV settings. I suggest using Kernel Tuner
From 384MHz to 702MHz I reduce 200mV
From 702 to 1.6GHz I reduce 150mV (Don't reduce more. Otherwise, your phone will reboot immediately)

Code:

  384000:   750000
  432000:   775000
  486000:   775000
  540000:   800000
  594000:   800000
  648000:   825000
  702000:   825000
  756000:   875000
  810000:   875000
  864000:   900000
  918000:   900000
  972000:   925000
1026000:   925000
1080000:   975000
1134000:   975000
1188000:  1000000
1242000:  1000000
1296000:  1025000
1350000:  1025000
1404000:  1037500
1458000:  1037500
1512000:  1050000
1620000:  1100000

Wiil try tonight and post the results.
My ROM at the moment is RR 537 CM12.

Well...as is the case with almost every OC kernel I've tried, the second core is stuck at maximum frequency. Kernel Tuner cannot make the settings stick. Any suggestions?

That's because of the mpdecision included in almost qcom devices. You can try the newest Kernel Tuner 2015 (with green icon). Or you can use these command in terminal:

Code:

su
stop mpdecision

BlackArtsInc · Apr 1, 2015

So I can use Kernel Tuner 2014 and be OK even after a reboot? OK thanks!

Sir

Thanks for the awesome kernel , everything works fine

Few requests

Can you check out and add commits from this kernel http://forum.xda-developers.com/xpe...rnel-thunderzap-4-1-r2-sound-control-t2390831 if you have time

Yes. I will include this feature in the 2.0 version. So you can use other apps to set CPU

Almost feature in that kernel was included in my kernel. Just enjoy the smoothness and longer battery life!

SOME REMARKS:

1) Is undervolt is really working? You know i have tried undervolting from inside ACPUCLOCK file but i didn't find any difference.
2) AFAIK mpdecision maintains clock speed disabling it will give you max freqs all the time.
3) Use intelliplug it governs frequency better than mpdecision.

There's only one method to make sure UV work: If you under volt more than 250mV and change cpu freq again, your phone will reboot immediately! That because voltage table will be read when cpu freq is changed
About the mpdecision, I've found a way to disable it. I found this code in init.qcom.rc

chown root system /sys/devices/system/cpu/mfreq
chmod 220 /sys/devices/system/cpu/mfreq
chown root system /sys/devices/system/cpu/cpu1/online
chmod 664 /sys/devices/system/cpu/cpu1/online
start mpdecision

service hostapd /system/bin/hostapd -dddd /data/hostapd/hostapd.conf
class late_start
user root
group root

Just delete this code and you'll have permission to control 2nd core.

Finally a fully working OC Kernel for CM12!

Been waiting for this for so long. Just installed it moments ago. FindYanot's kernel was working fine except that there was Camera and Flashlight FC issues. But no such issues in this one, so I am delighted. No other feature seems to be broken at the moment.

One question: Where to install Kernel Tuner 2015 from? Kernel Tuner 2014 was updated on Feb 28, 2015 according to Play Store, so is that gonna work as needed? (override mpdecision and set on boot)

It's KT 2014. Sorry I forgot the version.
Btw, the doubletap2wake function is now working. 2.0 version will be release soon!

Dude, can you add intelliplug to v2.0?
