( Installation )
If you have never installed a custom kernel on device:
You can:
1. Extract the latest kernel.bin.md5 from the zip, and installed it via Universal Kernel Flasher.
2. Use dd method below to install a custom kernel, and also you will have a custom recovery.
3. Make a Odin flashable package to flash custom kernel which will increase custom binary counter.
[Universal Kernel Flasher]
Thanks Frapeti for this tool!
[DD method]:
You need to ROOT your phone first.
1. Download kernel zips
2. Extract kernel.bin.md5 from zips
3. Copy kernel.bin.md5 to somewhere you like (e.g. /sdcard)
4. Open Terminal app,use these commands
Now lets go to superuser mode
su
Click to expand...
Click to collapse
Now lets flash(dd) kernel to kernel partition
dd if=/sdcard/kernel.bin.md5 of=/dev/block/mmcblk0p15
Click to expand...
Click to collapse
5. Reboot to take effects
reboot
Click to expand...
Click to collapse
* If you type a wrong dd command,it might hard birck your phone
So please think twice before hit enter
* WARNING: Think twice before you hit Enter,
some people bricked their phone because of a wrong command.
* Recommend SAFER recovery method
* It is recommended that check the md5 of kernel.bin.md5
If it doesnt match 'md5.txt' in zips,dont flash to phone.
Please re-download zips
[Recovery method]:
CoCore-E 4.0+ will only provide flashable zips.
Please flash custome recovery kernel first(3.3 or others).
Press Vol.Up + Home + Power to go to recovery.
Then choose zips in external/internal sdcard to flash.
( Uninstall )
Flash stock kernel to uninstall
dd if=/dev/block/mmcblk0p17 of=/dev/block/mmcblk0p15
Click to expand...
Click to collapse

2. Faq & how-to
( FAQ )
Q: What firmware does this kernel support?
A: All ROM bases on stock firmwares,all stock firmwares.
Click to expand...
Click to collapse
Q: Why my phone lags a lot!
A: Please check the cpu load.If it always goes very high,some apps are using cpu!And please check that you are not in PowerSaving mode.
Click to expand...
Click to collapse
Q: Why my phoen lags after booting in some minutes?!
A: Media Scanner is running in the background. More media files(especailly HD videos),more time it will take
Click to expand...
Click to collapse
Q: Why my phone cannot go to deep sleep when screen is off!!!
A: Fix it youself. It is app(s) taking the wakelock. Not kernel.
Click to expand...
Click to collapse
Q: Do I need to wipe anything when flashing this kernel?
A: NO
Click to expand...
Click to collapse
Q: My phone rebooted suddenly!!! What can i do?!
A: Give me /proc/last_kmsg and logcat. Will try my best to fix.
Click to expand...
Click to collapse
Q: Do i need to wipe data or dalvik caches?
A: No.
Click to expand...
Click to collapse
Q: Hey!Your kernel has issue!No-fills CPU shows me a wrong freqs!Fix it!
A: This is NOT issue.Every I9070 kernel will have this problem.Because No-fills will show you Dynamic Min/Max scaling freqs,DVFS(dynamic voltage and frequency system) will adjust Min/Max freq according to system load.
Open SetCPU,it shows you real freqs.Or check sysfs directly.
Click to expand...
Click to collapse
Q: My GPS doesnt work!?
A: Our Kernel only provides a trigger of enabling the GPIOs of GPS.It doesnt have GPS driver.
So check it in setting menu or try to reboot to fix or try to edit the region server of your GPS,remember to enable Wireless Position
Click to expand...
Click to collapse
Q: The audio volume is tooooo low in calls!!
A: My teammates diego and frapeti confirmed that this is baseband issue.
Flash newer firewares(at least LQB) or flash newer baseband directly.
Click to expand...
Click to collapse
Q: Hey my phone still lags after startup!
A: 1) Select another governor 2) Install Elixir(an app),tap Running,Select CPU usage filter,check which app(s) is taking cpu load!Then kill them.
In most caes,download provider is the battery and performance dainer! It runs when you download a file in browser like Chrome,it has a
serivice named Media Scanner,so dont remove it,just kill it.
Click to expand...
Click to collapse
Q: My phone cannot charge properly!
A: This is caused by your cable. Our usb switch driver has bugs right now(stock kernel too). We are fixing it. See here

( HOW-TO )
HOW-TO play with this kernel.
Terminal is needed.
If you get 'Permission denied', you need su permission.
If the devices lost responses, hold power button 8s to reboot.
Simply,You can cd to the folder first,then do echos.
Then `???` stands for the number to input.
It's a good idea that use SManager to add widgets on the launcher to switch tweaks!
I have uploaded my scripts in POST#5
( Boot time )
CoCore-E boots faster than stock normally.
Stock: 8000ms - 8500ms
CoCore-E: 7800ms - 8000ms
Click to expand...
Click to collapse
To check boottime
cat /d/boottime/summary
Click to expand...
Click to collapse
* TWRP kernel boottime is longer(around 8000ms). Because of that big ramdisk!
( Bootanimation )
Put bootanimation.zip in /system/media/.
Recommend you changing the permission to 0666.
If there is no bootanimation.zip, kernel will show Samsung's.
( CPU governors )
Performance, OnDemand(default), Powersave,
Userspace, Conservation, Interactive, InteractiveQ, PegasusQ, PegasusQPlus, HotPlug, OnDemandQ, AbyssPlug,
Smartassv2, Zzmoove, LulzactiveQ
Click to expand...
Click to collapse
* OnDemand has been patched cpu idle detection
* PegasusQ is taken from SiyahKernel (new version)
* PegasusQ recommended
* Most of custom governors are based on ondemand/interactive
* OndemandQ/InteractiveQ will hotplug cpu when screen turns off only.
* If you mind the battery life time, choose HotPlug. It hotplugs cpu frequently.
* Interactive updated to linux-android-3.4 [Thanks! Aditya!]
* Zzmoove is the new version(0.3)
* LulzactiveQ, it will hotplug CPU1
( CPUFREQ - DVFS )
Samsung DVFS is disabled by default now, since it conflicts with new cpufreq table.
Now we have took back the cpufreq control.
Use CPU control APP like SetCPU, no-frills CPU to set min/max cpufreq.
I created some fake interfaces in /sys/power/, so Power Saving mode still works.
To change the Power Saving max cpufreq: (default: 800MHz)
echo 600000 > /sys/power/cpufreq_dvfs_powersave
Click to expand...
Click to collapse
( LiveOPP - CPU OC/UC/OV/UV )
LiveOPP can control the properties of each cpufreq step.
LiveOPP values in /sys/kernel/liveopp
View all files in that folder first.
CPU freq table:
(Showed freq) : (Real freq)
200000 kHz : 192000 kHz
400000 kHz : 399360 kHz
600000 kHz : 599040 kHz
800000 kHz : 798720 kHz
1000000 kHz : 998400 kHz
1050000 kHz : 1049600 kHz
1100000 kHz : 1100800 kHz
1150000 kHz : 1152000 kHz
1200000 kHz : 1200000 kHz
1250000 kHz : 1228800 kHz
Click to expand...
Click to collapse
Overclocking depends on the device CPU quality you have.
You need to enable setting voltage in the slot first, if it is disabled:
echo set_volt=1 > arm_slot<id>
Click to expand...
Click to collapse
To decrease the voltage (UV) of a step: Example: @200MHz
echo varm- > arm_step0
Click to expand...
Click to collapse
To increase the voltage (OV) of a step: Example: @200MHz
echo varm+ > arm_step0
Click to expand...
Click to collapse
To change the voltage of a step:
echo varm=0x?? > arm_step<id>
Click to expand...
Click to collapse
* It means it accepts a HEX value only.
* ARM voltage is in 12.5mV steps
* Recommended that not tweaking Overclocking steps voltage
( GPU OC )
GPU clock controller valued in /sys/kernel/mali
Available interfaces:
mali_auto_boost
mali_available_frequencies
mali_boost_delay
mali_boost_high
mali_boost_low
mali_dvfs_config
mali_gpu_clock
mali_gpu_fullspeed
mali_gpu_load
mali_gpu_vape
version
Click to expand...
Click to collapse
Check mali_dvfs_config first.
mali_auto_boost
It's a simple GPU governor that can boost clock according to GPU load, enabled by default
To disable: echo 0 > /sys/kernel/mali/mali_auto_boost
Click to expand...
Click to collapse
mali_boost_delay
The delay of boosting frequency, in ms.
echo ??? > /sys/kernel/mali/mali_boost_delay
Click to expand...
Click to collapse
mali_boost_high
The high frequency performance profile.
Upthreshold: When GPU load is higher than this value, GPU clock will increase.
DVFS idx: DVFS data index in mali_dvfs_config.
echo ??????(a frequency) > /sys/kernel/mali/mali_boost_high
echo idx=??(a DVFS index) > /sys/kernel/mali/mali_boost_high
echo threshold=??? > /sys/kernel/mali/mali_boost_high
Click to expand...
Click to collapse
mali_boost_low
The low frequency performance profile.
Downthreshold: When GPU load is lower than this value, GPU clock will decrease.
DVFS idx: DVFS data index in mali_dvfs_config.
echo ??????(a frequency) > /sys/kernel/mali/mali_boost_low
echo idx=??(a DVFS index) > /sys/kernel/mali/mali_boost_low
echo threshold=??? > /sys/kernel/mali/mali_boost_low
Click to expand...
Click to collapse
mali_gpu_clock
Current GPU clock.
Say a frequency to tweak the clock directly.
echo ?????? > mali_gpu_clock
Notice! If auto-booster governor is enabled, this GPU will override.
Click to expand...
Click to collapse
mali_gpu_fullspeed
Value 1 means GPU is working at full speed.
Value 0 means GPU is working at half speed.
When on half speed, GPU clock will be divided by 2. Namely, 399 / 2 = 199 kHz.
Require full speed:
echo 1 > mali_gpu_fullspeed
Required half speed:
echo 0 >mali_gpu_fullspeed
Click to expand...
Click to collapse
mali_gpu_load
GPU load (aka: utilization)
Click to expand...
Click to collapse
mali_gpu_vape
GPU voltage on full speed.

( IO schedulers )
SIO(2012), SIO-Plus, VR, BFQ(v7r2), CFQ, NOOP, ZEN, ROW(v4), Deadline
Click to expand...
Click to collapse
* Default IO scheduler: CFQ
* SIO/ROW/SIO-Plus recommended!
( frandom module )
(5.3+) To enable FRANDOM kernel module:
insmod /lib/modules/frandom.ko
chmod 0666 /dev/frandom
chmod 0666 /dev/erandom
mv /dev/random /dev/random.orig
mv /dev/urandom /dev/urandom.orig
ln -s /dev/frandom /dev/random
ln -s /dev/frandom /dev/urandom
Click to expand...
Click to collapse
( Deepest sleep state )
Stock: 3 Default: 3
Deepest supported is 5.
To change:
echo 5 > /d/cpuidle/deepest_state
Click to expand...
Click to collapse
* PegasusQ(hotplug governors) works badly with 5
* OnDemand works well with 5
* Please note that it wont increase the using time but standby time.
* ( 6.0+)You can add an init.d script to tweak it 4 if you want
To check the cpuidle state:
cat /d/cpuidle/stats
Click to expand...
Click to collapse
( exFat sdcard )
In TWRP version kernel, it supports exfat sdcard.
Copy /sbin/libexfat.so to /system/lib
Insert exfat sdcard, use binary /sbin/exfat-fuse to mount
su
/sbin/exfat-fuse /dev/block/mmcblk1p1 /storage/extSdCard
Click to expand...
Click to collapse
Then tap mount sdcard in system settings to let system know sdcard is mounted
* Create an init.d script to mount exFat sdcard during startup
( zRAM SWAP )
[zRAM]
zRAM is optimized for Android. It is not lazy anymore. Recommended zRAM instead of SWAP.
Using zRAM will take a little CPU, because it needs to compress/decompress memory.
Recommended compressing about 18% of RAM, about 100 mb.
Setup disksize first: (example: 200mb)
echo $((200 * 1024 * 1024)) > /sys/block/zram0/disksize
Click to expand...
Click to collapse
* Larger size more RAM will be compressed.
* Too large size might make phone lag
To enable:
Code:
mkswap /dev/block/zram0
swapon /dev/block/zram0
To check how many does it use:
cat /sys/block/zram0/num_reads
cat /sys/block/zram0/num_writes
cat /proc/meminfo | grep swap
Click to expand...
Click to collapse
* We can get other info in its sysfs
[SWAP]
1. Format/resize external SDCard via computer first.
2. Create a new swap partition (mmcblk1p2)
Enable:
mkswap /dev/block/mmcblk1p2
swapon /dev/block/mmcblk1p2
Click to expand...
Click to collapse
2. Using a FILE as swap RAM: (Create a continuity file first)
su
cd /cache
dd if=/dev/zero of=swapfile bs=1024 count=81920
mkswap swapfile
swapon swapfile
Click to expand...
Click to collapse
Then we will have an 80mb swap RAM.
( Init.d script )
Please install busybox in system first
I recommend install busybox via apps
Create a new folder named 'init.d' in /system/etc
Set the permission of init.d foler to 0777(rwxrwxrwx) (at least has read and exec permission)
Set the owner to 0.0 (root root)
Put some scripts (any name you like) in init.d folder with permission 0777 (rwxrwxrwx) (at least has read and exec permission)
Scripts with right permission will be executed when system boots.
( Charger Control )
Please note that this control can damage your battery/phone.
If your battery/phone damaged, read the top of #1 post.
Lower current makes the charging longer, but protects battery.
On our board, the highest safe current is 900mA
( 6.8- ) See here,6.8+ has used new entries
( 8.6+)
To enable Current Control:
Setup current first: (for example, 900mA)
echo 900 > /sys/kernel/abb-charger/charger_curr
Click to expand...
Click to collapse
Turn on Current Control:
echo on > /sys/kernel/abb-charger/charger_curr
Click to expand...
Click to collapse
Turn off Current Control:
echo off > /sys/kernel/abb-charger/charger_curr
Click to expand...
Click to collapse
* The Custom Current must match the value in the Current Table
* InputCurrent and OutputCurrent are read from charger registers,
* If we find that this sysfs interface prints "VBUS DROPPED!" warning,
The charging current has been changed by driver because of a BAD charger!
* It need to plug/replug charger to take effect!
To enable Charger HW Control:
If we want to transfer data or stop charging, we can disable the charger:
echo off > /sys/kernel/abb-charger/charger_hw
Click to expand...
Click to collapse
To enable:
echo on > /sys/kernel/abb-charger/charger_hw
Click to expand...
Click to collapse
( Cycle Charging Control )
Similar to BLX by Ezekeel. It can be used to limit the battery charging level.
Example: Limit the battery level at 70% ~ 75%
Enable:
echo on > /sys/kernel/abb-fg/fg_cyc
Disable:
echo off > /sys/kernel/abb-fg/fg_cyc
Discharging threshold (battery level %):
echo dischar=75 > /sys/kernel/abb-fg/fg_cyc
Recharging threshold:
echo dischar=70 > /sys/kernel/abb-fg/fg_cyc
Click to expand...
Click to collapse
( USB Power Sharing )
( 6.2+) This can enable the internal vbus power supply for usb devices.
But the phone still cannot recognize our usb devices now.
We can use it for fun, like charging for other devices, USB fan...
cd /sys/kernel/abb-regu
echo 1 > VOTG
Click to expand...
Click to collapse
* Say 0 to VOTG to disable
* Plug OTG cable first, then enable it
( USB Switcher )
Sometimes, we will lost the ADB connection after a reboot.
This is the software workaround to fix this issue, namely, SW reset the USB swticher.
echo 1 > /sys/devices/virtual/usb_switch/FSA_SWITCH/swreset
Click to expand...
Click to collapse

---

3. HOW TO
( WiFi PM Mode )
We can tweak WiFi screen-off PM mode now.
PM FAST is used by default to speed up, PM MAX is used to save power
To switch to PM_MAX:
echo 0 > /sys/module/dhd/parameters/dhdpm_fast
Click to expand...
Click to collapse
( MMC SPI CRC )
Disabling SPI CRC can improve mmc performance (10%)
But phone may freeze randomly.
echo 0 > /sys/module/mmc_core/parameters/use_spi_crc
Click to expand...
Click to collapse
( Real charged notification )
Well, please let me call it notification.
To be honest, it needs to check manually.
( 6. For old versions
cat /sys/kernel/abb-chargalg/eoc_status
Click to expand...
Click to collapse
* You can use Root Explorer to view these files in /sys/kernel/abb-chargalg
* When it says "First eoc reached", then the UI should show you charged 100%
But it is not the real full charged.
* When it says the real EOC reached, unplug the charger.
* According to my experiments, it needs 1-2 hours to charge to real full after it shows you 100%
( POnKey Emulator )
Because my power key is going to break, so I need this feature.
This is the software emulator of power key.
To turn off screen: ( 20 < value(ms) < 520 )
echo 100 > /sys/kernel/abb-ponkey/emulator
Click to expand...
Click to collapse
To active the power menu: ( 520 < value(ms) < ∞)
echo 800 > /sys/kernel/abb-ponkey/emulator
Click to expand...
Click to collapse
To use Vol.Up or Vol.Down key as Power Key:
echo volup=1 > /sys/kernel/gpio-keys/ponkey_emu
OR
echo voldown=1 > /sys/kernel/gpio-keys/ponkey_emu
Click to expand...
Click to collapse
* It doesn't work in suspend expect in charging.
( ABBamp Audio )
Please note that listening to too high volume music over 1 hour or more can damage your ears.
Too high volume can make your external speakers/headset overload or damage them.
( 6. Old versions,please see here
Credit: Aditya(Adi_Pat)
First, why do i call it `AMP`?
Because most of our tweaks are about gain(volume)
Our codec is simple, It doesn't have any hardware EQ (although i want...)
ABBamp sysfs entries are in:
/sys/kernel/abb-codec
Click to expand...
Click to collapse
* Use RootExplorer to view this folder,there are lots files
Tweaks will take effects immediately!
Most tweaks will accept inputs like "on", "off" (no quotes)...
So, say "on" to enable this tweak, then this tweak will apply the value stored/inputed
View(cat) these files, most of them will give you useful infomation about this tweak.
They will show you the volume in dB of gain
`cd` to /sys/kernel/abb-codec first then do echos, will be more convenient.

Let me clear the panel brightness for you:
The brightness of our panel is depends on gamma
The gamma is generated according to illumination value
We have 26 levels of gamma, means we have 26 illumination values too
So the brightness in system like 1 and 6 are the same brightness in kernel driver(converted),
Because 1 and 6 are in the same gamma level.
Check the file gamma_table to see, the gamma valeus are the same
Unlocked brightness:
In non power saving mode,
We allowed 255 brightness uses the maximum gamma level(25) in kernel driver
In power saving mode,
The maximum brightness can be set is around 230(not 255).

This can control this brightness of panel
You can write any value to it, maximum proper illumination is 300

Current: [??] ??? Shows you which index is using
The index0 is the minimum brightness(namely in power saving mode).

For example:
Tweak index0 illumination:
echo 0 10 > illumination_table

* 0 is the index
* 10 is the value
* If you are in power saving mode now,the brightness will change!

* Keep this default if unsure.
Mali Utilization control
(Default: low_to_high 192 high_to_low 64)
Our driver will report a mali utilization frequently.
This utilization(range: 0~255) means the load of mali.
If utilization is bigger than low_to_high, driver will request higher hardware performance(highest APE/DDR OPP).
If utilization is smaller than high_to_low, the driver will store the requested OPP(uses low OPP).
OPP can be understood as freq simply.
To check mali utilization values:
echo 5 > /sys/module/mali/parameters/mali_debug_level
cat /proc/kmsg | grep -i utilization
Click to expand...
Click to collapse
When it says SIGNAL_HIGH, it will request highest OPP.
When it says SIGNAL_LOW, it will request lowest OPP.
Press Ctrl+C to stop printing.
