Installation

Step 0:

This Step is only needed if you need to update to Android 4.x.x as it's required for this ROM and Kernel.
If u've already Android Version 4.1.2 or even 4.4.x installed, then go to Step 1.

Update to the latest Samsung Stock ROM 4.1.2 with ODIN.
All the needed Files u'll find it in the FTP Server, Click!
Make sure your Battery is at least charged at 70% before u proceed.

I'm a noob, please show me more details:

Download needed Files for Windows (for other OS, please search the Web):

Samsung USB Driver for Mobile Phones and odin3_v3.07.zip Offline flasher:
http://www.xda.mister-freeze.eu/XDA-...I8160/General/

Stock ROM:
http://www.xda.mister-freeze.eu/XDA-...160/Stock_ROM/

For the GT-I8160 you need:
I8160XXMB4.zip (3-parted)
and
ONE-I8160XXNF2-20140930142454.zip (Latest Stock ROM)

For the GT-I8160P you need:
CODE_GT-I8160P_I8160PXXLK2_CL1211774_REV00_user_SEC_KEY_XL K2_4G.zip ( first 3-parted)
and
CODE_GT-I8160P_I8160PXXME1_DBT_1106830_REV00_user_low_ship .zip (second 3-parted)
and
DBT-I8160PXXMG2-20130820164646.zip (Latest Stock ROM)

For the GT-I8160L you need:
GT-I8160L-3parted.zip (3-parted)
and
PGU-I8160LUBMK2-20140603151522.zip (Latest Stock ROM)

After u've downloaded the needed Files and u've unpacked and installed the Samsung USB Driver, u can proceed wit the upgrade.
Note: All your data will be deleted, so it's recommended to backup some important files to your Computer, including the content of your sdcard.
First of all, export all your Contacts to your ext-sdcard. Later you will need this File in order to import your Contacts into the new ROM because the new ROM CM11 has a small issue that it can't read SIM-Contacts.
Now copy the exported contacts to your PC and then format the sdcard as FAT32 if u can, if u don't know how to do that, it's also (for now) enough to simply delete all files and folders from the sdcard.

Unpack Odin3_v3.07.zip and open the Program inside, it's: Odin3 v3.07.exe

Unpack the ROM, for example we unpack the ROM: I8160XXMB4.zip for the GT-I8160 which is a 3-parted Stock ROM.

Well, now Power OFF the Phone and remove the sdcard.

Press and hold at the same time: Volume down + Home + Power Button.
The Phone will boot directly to "Download Mode", now press "Volume Up" to enter "Download Mode".
Connect the Phone with your PC with the original USB Cable (important: during flashing don't turn off your pc or phone, also don't touch the Phone or the USB Cable)
Your Phone should be recognized by ODIN .. u can see this in "ID:COM"
if not, then the USB Drivers for samsung mobiles are not properly installed !

Don't change the check boxes !!!

Now load the *.tar.md5 files as following into ODIN:

PDA = HOME OR CODE (*.tar.md5)
CSC = CSC (*.tar.md5)
PIT = *.pit File (the checkbox Re-Partition is now checked )

Wait until the MD5 Check is done and proceed by adding the next package in ODIN.
Before u press "Start", make sure everything looks like this:
For 3-parted Stock ROM:
http://www.xda.mister-freeze.eu/XDA-...in_3parted.png
For latest Stock ROM:
http://www.xda.mister-freeze.eu/XDA-...neral/odin.png

Finally press "Start" - Wait patiently ... this takes around 7 Minutes.

The Phone will reboot several times. When u see the pad for entering the SIM PIN ... then the (3-parted) ROM was flashed successful and u can now remove the USB Cable and reset ODIN and u should flash the next ROM with ODIN which is:

ONE-I8160XXNF2-20140930142454.zip (Latest Stock ROM)

flash it exactly like the 3-parted one, with the difference that it's only one File to add in ODIN .... see the Screenshot "For latest Stock ROM" which is odin.png.

In General the order should be exactly like it's already listed here above !
That means:

1. flash "first 3-parted" and wait till it's fully booted up ...
2. flash "second 3-parted" (GT-I8160P only) and wait till it's fully booted up ...
3. flash "latest Stock ROM" and wait till it's fully booted up ...

Step 1:

Download needed Files and copy them to your micro sdcard, DO NOT unpack them!:

Temp_CWM_6.0.2.8.zip:
Click!

CM11:
Click!

Kernel for the three Models, sdcard_only is recommended (for optimal functionality, note: micro-sd is required) OR normal version if u want to use the phone with internal + micro sdcard or simply without micro sdcard:
Click!

cwm_cm11_partitions_layout_sdcard_only.zip(for sdcard_only version) OR cwm_cm11_partitions_layout.zip (for normal kernel version):
Click!

gapps are required for Google Play:
Click!
Choose ARM - 4.4 - pico
OR if it doesn't work well, then use this tested package from FTP Server:
Click!

Swype_fix.zip:
Click!

Explicit for GT-I8160P, download GT-I8160P_Support_Vx.x.zip:
Click!

Explicit for GT-I8160L, download GT-I8160L_Support.zip:
Click!

Step 2:

Power OFF Your Ace 2
boot to recovery:
Press and hold at the same time Home + Volume UP + power button till it'll vibrate.
Navigate with Volume Keys to "apply update from external storage" and confirm always with "Power-Key"
Choose "Temp_CWM_6.0.2.8.zip" and confirm.
"install zip from sdcard" and confirm.
"choose zip from sdcard" and confirm.
Choose "a2n_kernel_gt-i8160_4.4.4_sdcard_only.zip OR a2n_kernel_gt-i8160_4.4.4.zip" and confirm
Hit "Back Key" few Times and select "reboot system now"
When then Screen is black immediately boot directly to recovery again.
Now the cwm version should be 6.0.5.0.

Step 3:

Increase the available space for Apps from 1,2GB up to 3GB !
More Informations about the Repartition: Post #3

This Step is optional, so if you don't plan to install a lot of apps you can skip this and go to Step 4.

flash cwm_cm11_partitions_layout.zip OR cwm_cm11_partitions_layout_sdcard_only.zip
press several times the soft back-key, then press "advanced" and "power off"
boot again to recovery
mounts and storage
format /system
format /storage/sdcard0 as "vfat" [it's like FAT 32]
Go back and "wipe data/factory reset"
advanced
power off

Step 4:

If you performed Step 3 then Boot to recovery otherwise

flash CM11 (GT-I8160_Support.zip already included)

in addition for GT-I8160P (for the NFC Model):
flash GT-I8160P_Support_Vx.x.zip

in addition for GT-I8160L (for the Latin Version):
flash GT-I8160L_Support.zip

Flash latest Kernel:
a2n_kernel_gt-i8160_4.4.4_sdcard_only.zip
OR
a2n_kernel_gt-i8160_4.4.4.zip

Flash gapps

Finally flash Swype_fix.zip

Reboot system now

If it asks for root, just say NO (it's cwm bug)

DONE !

Info 2 Useful Tips
Activate Developer Options

Go to Settings ---> "about phone" and tap several times to "build number"

3-Way Reboot Menu

Go to Settings ----> developer options and enable: "advanced reboot menu"

Faster Animations

in developer options set all 3 Animator times from 1.0x to 0.5x

CM Performance Profiles

This ROM and Kernel has 3 Performance Profiles:

Powersave:
CPU: min 400 max 600 MHz
GPU: min 0/225/450 max 450 MHz

Balanced (default):
CPU: min 400 max 800 MHz
GPU: min 0/225/450 max 500 MHz

Performance:
CPU: min 400 max 1000 MHz
GPU: min 0/225/450 max 500 MHz

On Suspend CPU min_freq is always 200 MHz.

How To make SpiritFMFree working:

Open SpiritFMFree App, go to Setting ----> Audio ----> Method ----> "Galaxy S3/Note/S2_ICS"

Tips for max SOT (screen on time)
  • Use "Performance" Profile
  • Enable FSB OC
  • Make sure 2/3G Signal is good (if it's bad toogle 2/3G)
  • Try to use more 2G than 3G
  • Use always the lowest possible LCD Brightness
  • Disable zRam and use KSM instead
  • Try some undervolting in A2N Kernel Control App
  • Disable all features you don't need
  • Set CPU "Suspend Max Frequency" to 400 MHz
  • Uninstall Apps you don't need at all
  • Eventual replace the Battery with a new one or replace it with higher capacity

Changes after the Repartition

cwm_cm11_partition_layout_sdcard_only.zip
  • The total space from sdcard0 will moved to /data - so that's why a real sdcard is mandatory here.
  • /data is 3GB for apps - max. possible!
  • No problems with Apps installations
  • No wasted space !

cwm_cm11_partition_layout.zip
  • sdcard0 will be added with 1GB Size... and u're able to use also micro-sdcard (sdcard1)
  • /data is 2GB for apps.
  • No wasted space !

For Reference purposes, the original partition layout has following setup:
  • sdcard0 is 1,1GB
  • /data is 1,2GB for apps
  • Some wasted space and too low free space for installing Apps.

How to disable EOC(end-of-charge) BLN(backlight notification) for LPM(offline-charging) + Recovery

Open "FileManager" ---> Settings ---> "General settings" ---> access mode --> "root access mode"
go back and navigate to the root "/" open the file user_lpm.rc and uncomment the corresponding line.

example:

Code:
on boot

# Disable end of charge BLN
#   write /sys/kernel/abb-chargalg/eoc_bln 0

# LCD Brightness (default 100 - max 255)
#     write /sys/class/backlight/panel/brightness 50

# Disable Sweep2Wake
#	write /sys/module/sweep2wake/parameters/enable 0
uncomment:
Code:
on boot

# Disable end of charge BLN
   write /sys/kernel/abb-chargalg/eoc_bln 0

# LCD Brightness (default 100 - max 255)
#     write /sys/class/backlight/panel/brightness 50

# Disable Sweep2Wake
#	write /sys/module/sweep2wake/parameters/enable 0
Now EOC is disabled for offline-charging.
The same procedure is for "user_recovery.rc" if want to disable it as well in recovery mode.
Also there u can do other things, like enable/disable sweep2wake or change the lcd brightness for LPM or recovery.

REPORTING BUGS

First of all:
make sure u're running the latest Version of ROM, Kernel, and Kernel Control APP Provided by this Thread.
Bofore u want to report bugs or post some logs, u should make sure that u're NOT using any CPU/GPU OC/UC/OV/UV at all.
Also revert first all ROM changes made by i.e. XPosed, AutoRunManager, task killer, Disabled Services, Greenify and so on ... then u can proceed:

Open "A2N Kernel Control Demo" App and press the left soft-key menu button and select "debug"
there u'll be able to export logs to your sdcard and then u can post them here in the Thread to get some help or help with debugging.

Thanks for your interest in this Kernel !
Please rate this Thread and my App in Play Store and leave a nice comment. - Thank you!.

The Procedure is the same like Rox's CM11 ... just download the right Kernel / Build / ROM.. and copy this in your sdcard1 ... do not unpack it.. as .zip is fine. Then turn your Phone Off... And press together till it will vibrate: Volume up + Home + Power.

Chose now:

Wipe Cache
Go advanced
wipe dalvik cache
go back
install zip from sdcard
install zip from sdcard1
choose the Kernel and flash it..
go back and reboot system..
That's it !

If u like clean install, then choose wipe data instead of wipe cache ! But all your apps and settings are gone.
If u are running CM 11 .. then wipe data is not needed... even if u like to flash my ROM Builds... wipe cache and wipe dalvik is enough... but if u have 10.1 or 10.2 .. u need to wipe data first !

PS: Kernel for codina and codinap 20141028 online !!!!!!!!!!!
