Installation​
Step 0
This step is only needed if your Android version is lower than 4.
If you have already Android 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.
Make sure your battery level is at least 70 % before you 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
odin3_v3.07.zip offline flasher
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_XLK2_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 you've downloaded the needed files and you've unpacked and installed the Samsung USB Driver, you 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 you can, if you 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 +" to enter "Download Mode".
Connect the phone with your PC with the 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 .. you 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 follows into ODIN:
PDA = HOME OR CODE (*.tar.md5)
Wait until the MD5 check is done and proceed by adding the next package in ODIN.
CSC = CSC (*.tar.md5)
PIT = *.pit File (the checkbox Re-Partition is now checked )
Before you press "Start", make sure everything looks like this:
For 3-parted stock ROM:
http://www.xda.mister-freeze.eu/XDA-files/ace2nutzer/GT-I8160/General/odin_3parted.png
For latest Stock ROM:
http://www.xda.mister-freeze.eu/XDA-files/ace2nutzer/GT-I8160/General/odin.png
Finally press "Start", be patient ... this takes around 7 minutes.
The phone will reboot several times. When you see the pad for entering the SIM PIN ... then the (3-parted) ROM was flashed successfully and you can now remove the USB cable and reset ODIN and you 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.
Step 1
Download required files and copy them to your micro sdcard without to unpack them:
Temp_CWM_6.0.2.8.zip to your sd-card, do not unpack it.
CM11
A2N Kernel (choose normal version, or if you want to increase the space for apps, then choose "sdcard_only", but you need micro-sd-card and you should perform re-partition - very easy - step-by-step)
Optional re-partition:
cwm_cm11_partitions_layout_sdcard_only.zip (for sdcard_only version) OR
cwm_cm11_partitions_layout.zip (for normal kernel version):
gapps (required for Google Play)
Choose ARM - 4.4 - pico
OR
if it's no longer available, then use this version from FTP-Server
Swype_fix.zip
Explicit for GT-I8160P, download GT-I8160P_Support_Vx.x.zip
Explicit for GT-I8160L, download GT-I8160L_Support.zip
Step 2 (only required if your device has no cwm recovery)
Flash a2n_kernel_gt-i8160_ODIN.tar with ODIN in order to have CWM recovery or boot to stock recovery in order to flash temp_cwm.
Step 3 (optional)
Increase the available space for apps from 1,2 GB, up to 3 GB !
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 tap
"advanced"
"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"
Boot to cwm
Go to step 5
Step 4
"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"
boot to recovery
Step 5
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 open-gapps
Finally flash Swype_fix.zip
Reboot system now
Be patient, it takes around 5 minutes for the first boot.
DONE !

Useful Tips / FAQ
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.
How to Setup SpiritFMFree
Open SpiritFMFree app, go to setting ----> audio ----> method ----> "Galaxy S3/Note/S2_ICS"
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 3 GB for apps - max. possible!
No problems with apps installations
No wasted space !
cwm_cm11_partition_layout.zip
sdcard0 will be added with 1 GB size... and you're able to use also micro-sdcard (sdcard1)
/data is 2 GB for apps.
No wasted space !
For reference purposes, the original partition layout has following setup:
sdcard0 is 1,1 GB
/data is 1,2 GB 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 check the content.
The same procedure is for "user_recovery.rc" if want to disable it as well in recovery mode.
Also there you can do other things like enable/disable sweep2wake or change the lcd brightness for LPM or recovery.
FAQ
Q: Is this Kernel 100 % Safe ?
A: Yes.
Q: Will this Kernel Overheat the Phone if I use Highest Settings ?
A: No, you can't do anything wrong. Your phone has hard- and software overheat protection.
Q: How to Revert all Changes Made by this Kernel ?
A: Flash latest 3-parted stock ROM with ODIN.
Q: How i can Tune this Kernel ??
A: Everytime you install or update this kernel you will face an red (demo) app "A2N Kernel Control..." open this app, and it'll redirect you to Google Play to get the full version (blue app).
Q: Can i use and Tune your Kernel with other Kernel Manager Apps ?
A: Yes, but you need first to unlock kernel with the A2N app full version.
Q: I've Installed the Full Version of the App, Will it Change any Kernel Settings by Default if i do not Change them ?
A: No, default app settings = default kernel settings.
Q: I've the Full Version of the A2N Kernel Control App, Do i still need the Demo Version of the App ?
A: Yes, there are some special features in-app-menu like "Fake Enforce" and debugging features for easy bug reports.
Q: How to Charge from 10 % to 100 % In just 1 h ?
A: E.g. set "AC Current Max" and "Maximum Charging Temperature" to the Max.
Q: Can i use your Kernel Control App with other Custom Kernels ?
A: No, it's not universal kernel manager app.
Q: My A2N App shows: "Please check your internet connection" - But i've good internet connection. - How to fix it ?
A: Settings --> network settings --> use private DNS server like "dns.adguard.com" - confirmed to work by user @Arnz09 - see his post here.
Q: My A2N App is Crashing after an Update, how to fix it ?
A: Re-install it. If it doesn't help, wipe dalvik-cache in recovery.
Q: How to Report Bugs ?
- Please DO NOT report bugs if you are:
--- using "unsafe" Freqs
--- not using the latest release !
--- not using Samsung stock ROM (based stock ROMs are custom ROMs !)
A: Open the red A2N Kernel Control demo app and check in-app-menu (3 dots) then "Debug" and then on "logcat and dmesg" if you faced an app crash or if some features didn't work.
If the phone rebooted randomly, then tap on "last_kmsg". You will find the logs in your internal storage. After that you can attach them here in your bug report, by clicking "Attach files".

Any download links for kernel?

Nice to have another kernel. Is it really stable yet?

---

where is build 27.10? I cant find it, only build p1 for now.

---

I'm actually writing in the Thread.. sorry..... Downoad link added.
20141028 Version, shall be the first very stable Kernel Version.. because of CPU / GPU Stock Voltages and freq.
10/27 never exists.. and 10/28 I'll upload it in 1 Hour....
Please be patient.. let me finish writing the Changelog..

Hi @ace2nutzer!
First of all, thank you very much for your work!!
Can you explain how to install kernel and ROM?? (i've never flashed a kernel... i have no idea...)

---

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 !!!!!!!!!!!

Another Great Kernel for Ace 2. NUFF SAID!
Keep it up ace2nutzer. Good job.

---

@ace2nutzer I cant falsh new build, because I cant go to cwm, I use p1 kernel from you and cant go to cwm, always blackscreen.

No, just cant go to cwm, I get blackscreen. My device boot normally.

---

diference ?
what is the main diference between 3.2 and 3.0 that you make ?
how distinguish these two kernels ?
BTW we evolve so no need to make kernel for 4.3.x because all apps are optimizing for 4.4.x OS slowly so more need is to work on kernels I appreciate that ...
Will there be ART support in kernel ? so we can later adapt L 5.0 ?

---

Could you also include OndemandPlus governor? Its best on Galaxy Nexus devices. May be here as well.

Ok.. I' don't have this Problem... perhaps it is related to the famous s6d Driver
I've builded a odin Version for u.. it is the same kernel ----> 10/28 .. flash this with odin.. and tell me if u can enter in CWM...
I've uploaded it for u.. : codina_kernel_ODIN_cm11_20141028_ace2nutzer.tar - 10.99 MB
If not, i can do nothing.. but don't worry.. i can always do separate Odin Kernels.. then u can flash at this way my kernel updates.
An another way is over ADB... just check also if u have access with ADB.... just boot into CWM.. and even with black screen.. connect the Phone and start ADB.. try if u have access... u can do all the things with ADB.. that's all the same.. and u can even wipe cache and dalvik cache with FileManager.. all no problem

---

Good job @ace2nutzer
Gonna try it as soon as the f2fs support is ready

---

Is your ROM compatible with f2fs???

I can't enter CWM too. I wrote lots of post about that and no one really care about it.
I'll tell you what happened:
I bought my Ace II, stock recovery works great. I've installed temporary CWM and everything was ok. I've installed old CM11 TC and Nova versions and everything was ok.
When Chrono made his first kernel version with a CWM built in, i had the first black screen issue. Since there, i cannot enter any recovery (CM11 cwm, chrono cwm, stock cwm). Only TWRP works good but it can't mount external SD and i don't feel comfortable with it. I never had screen issue, never had a problem since now.
Solution: it randomly let me enter on recovery, but it's a pain in the ***.
I've tried to format everything, i also installed GB stock with stock repartition, nothing to do.
With this version i've tried lots of time but still cannot enter. Can you try changing CWM version? Maybe a older one, or just a different one. I can test it if you need help.
Actual situation: i've installed this kernel with your CM11, i had some bugs that i can fix formatting some partition, nothing bad. But i can't enter on recovery, so i have to flash stock version with odin -.- I suggest to make a stable version and then focus on those issues, i bet other users have them.
I've tried to flash kernel via Odin... Failed, dunno why
