Frequently Asked Questions​
For NOOBS​
Q) How to flash the kernel
A) Just apply update.zip from Recovery or flash tar file using ODIN.
Q) Will i lose my data if i flash kernel?
A) No, you wont lose any data nor do you have to wipe data or cache.
Q) Does my battery need to be 100% to flash?
A) Not at all
Q)Flashed CM 6.2 Kernel on Froyo Rom and WIFI doesnt work?
A) There are two versions of Kernel. One is for Froyo Rom and other is for CyanogenMod Rom 6.2 (CM 6.2). if you are on Froyo rom and flash CM 6.2 then your wifi wont work and vice versa.
Q) 1400 Mhz (Extreme version) doesnt work for me
A) Not all Galaxy 3 suppport overclocking as high as 1400 Mhz. If it doesnt work then keep frequency lower or flash Ultimate, Performance or Lite version
Q) What does this data2sd in g3mod do?
A) data2sd is method by which all your /data partition goes to your sdcard thus giving you more space for downloading apps. Its suggested to use data2sd only if your sdcard class is higher than Class 6
Q) Internel Memory shows 0kb
A) Check if you have fs.data2sd at this location /sdcard/Android/data/g3mod/ If yes then delete it or else your sd card doesnt have sd-ext partition
Q) How can i go to recovery mode
A) Press MENU+VOLUME UP+VOLUME DOWN+POWER button and bingo!!!
Q) Should i use multi boot even if i am having 2 gb card class 2 ?
A) Sd card with any class can use multiboot
Q) Data Wipe Necessary When Switching Between CM and Froyo ?
A) Yes data wipe is necessary for switching roms between CM and Froyo. But we have given option to Backup data also in recovery.
Q) My APP is not working after Flashing KERNEL
A) Its not a kernel problem
Q) What is tun.ko?
A) It is basically used to setup Open VPN connections
Q) What is jhash3?
A) jhash3 improves the HSDPA/3G/EDGE speed
For Advanced users​
Q1) Battery is draining fast?
A) After flashing the kernel please calibrate your battery or else let 3-4 full battery cycles pass.
Q2) Which profiles should i use?
A) Lets take example that you are using Ultimate kernel. Keep the governor ondemand (Like every good boyfriend fulfills all demands of his girlfriend ondemand governor does the same for your CPU ).
Make profiles:-
1) Time Profile - 12 am to 6.00 am Freq 100 Mhz to 400 Mhz Priority 100
2) Screen Off - Freq 100 Mhz to 600 Mhz Priority 95
Q3) What are advanced settings in the SetCPU mean?
A) Sampling rate is rate at which the frequency of your CPU changes. Up Threshold is limit at which CPU will change freq on load (Scales Up). Down Threshold (conservative only) is limit at which CPU will change freq on load (Scales Down). Powersave bias is used for saving the power of CPU, it will slow down the CPU and affect the performance also 200 in powersave bias mean 20%...250 means 25% and so on.
Q4) I want performance and also good battery what profiles should be i use?
A) Refer to Q2 for Profiles Set up and now go in Advanced tab and Keep Sampling Rate 10000 or 15000. Upper Threshold to 90 and Powersave bias to 200 (20%). Since we are using powersave bias, this will affect the performance as it slows down the CPU so to increase the performance we are lowering the Sampling rate thus we get perfect balance of Performance and good battery backup.
NOTE: ABOVE SETTINGS ARE JUST EXAMPLE..PLEASE PLAY AROUND AND CHOOSE SETTINGS WHICH SUITS YOU THE BEST

Steps for Multi boot:
1) Flash Kernel v1.7+
2) Go to CWM Recovery -> Multiboot -> Backup ROM.
3) Backup your Current ROM to ROM1 (It will backup the system.img at /sdcard/Android/data/g3mod/roms/romname_ROM )
4) Add the system.img of your 2nd ROM to /sdcard/Android/data/g3mod/roms/romname_ROM and similarly for different ROM's.
5) Use the CWM Recovery -> Multiboot -> Switch ROM option to switch between different ROM's.
6) If switching between Froyo ROM and CM6.2 RoM, you will need to wipe data and also change kernel's via update.zip method.
7) Use the data backup and restore option to prevent loss of data when switching between Froyo and CM6.2 ROM's.
Note: Ask the developer of the ROM's to provide you with the system.img for their ROM
How to use Hybrid Data2SD
1) Connect your phone via ADB
2) Go into adb shell
3) Type 'echo hybrid > /sdcard/Android/data/g3mod/fs.data2sd'
4) Create a text document in Notepad with a list of all the directories you wish to move. Example:
Code:
app
log
dalvik-cache
---LEAVE A BLANK LINE AT THE END---
5) Save the file and call it 'data2sd.dirs'
6) Do 'adb push data2sd.dirs /sdcard/Android/data/g3mod/'
7) Reboot your phone
8) Once your phone has booted, run 'adb shell cat /data2sd.log' to ensure it is running correctly.
How to enable Multi Data
1) Connect your phone via ADB
2) Go into adb shell
3) Type 'echo 0 > /sdcard/Android/data/g3mod/multiosdata'
4) Multi Data will automatically backup your data upon booting into a different OS.
Make sure to not wipe your SD-EXT partition. Doing so will erase the backups from other firmware. Only wipe it if you wish to erase data for everything.
You can also use Multi Data to quickly restore data if your phone has become corrupted. It will restore it back to the last multi-boot switching
1) Connect your phone via ADB
2) Go into adb shell
3) Type 'echo 0 > /sdext/lastos'
4) Reboot the phone
Directories for Multi boot:
//ROM Dir
__system("mkdir /sdcard/Android/data/g3mod/roms/CyanogenMod6_ROM");
__system("mkdir /sdcard/Android/data/g3mod/roms/CyanogenMod7_ROM"); //Add CM7 Support
__system("mkdir /sdcard/Android/data/g3mod/roms/G3MOD_ROM");
__system("mkdir /sdcard/Android/data/g3mod/roms/Kyrillos_ROM");

__system("mkdir /sdcard/Android/data/g3mod/kernel/CM6");
__system("mkdir /sdcard/Android/data/g3mod/kernel/CM7");
How to configure compcache:
If you want to use default configuration (as up to now.. 62 MB aprox.), you don't have to do anything different as what you have been doing. But if you want to use a more/less memory, here are the steps:
Inside that /sdcard/Android/data/g3mod/compcache file, write ONLY the number of MegaBytes you want to use for compcache.
Reboot.
If compcache file is empty or contains a "0" inside, it will use default configuration.
How to: BLN
This is only "needed" if you have a i5801 | i5800L or any other Galaxy 3 model with back button lights and want BLN in it.
How to install:
First, download the lights.GT-I5800.so file from google code. Then execute this commands:
adb remount (or if this doesn't work: mount -o remount,rw /dev/stl6 /system)
adb rm /system/lib/hw/lights*
adb push [Location of this file] /system/lib/hw
After that, reboot and now you have BLN working
Steps for Changing the Max Freq(Dynamic OC):
There is an entry in /sys/devices/system/cpu/cpu0/cpufreq/plls_table where you can put your own value for APLL.
Before doing this, set "PERFORMANCE" governor on and min and max frequencies to the maximum.
Code:
// Do this in adb
echo "0 a[SIZE="5"][B][U]258[/U][/B][/SIZE]0[SIZE="5"][B][U]3[/U][/B][/SIZE]01 a14d0303 c07e13fc cf850240" > /sys/devices/system/cpu/cpu0/cpufreq/plls_table
You need to replace the 258(Hex Value) with your desired value.
Here 258 means
(2*16*16) + (5*16) + 8 = 600
and 3 means it is 600*2 = 1200
Therefore, a2580301 means 1200MHz.
This is a temporary method. For a permanent Method, add this line to a init.d script. Name the script to something like S10_Dyanmic_OC.
Help Others: If you calculate a Hex Value for a particular frequencies add it here:
https://docs.google.com/spreadsheet/viewform?formkey=dG5hdnpsWFdTNExiY2t3dy16VzBvaWc6MQ
You can view all the frequency Hex value's calculated by others over here:

Note:
We am learning how to develop kernels.
We willl add different features as and when we can implement them.
The main goal of this kernel will be to keep the phone stable and fast.
There will be nothing as alpha or beta releases.
We will give out the kernels directly, but if anything goes wrong and you have to reflash the ROM or kernel, please dont start shouting.
You may give us different ideas on what features to implement. We will try our best to implement all the features you want
Many of the features implemented in this kernel, are taken from marcellusbe's Fugumod Kernel, and we shall be ever thankful to marcellusbe for the fugumod kernel
Warning:
We are not responsible for any damage caused to your phone (softbrick or hardbrick)

Credits:
marcellusbe for all his help, awesome fugumod kernel
supercurio for voodoo v10
Paolo for BFQ I/O Scheduler
All developers for making this an awesome phone
Everyone who is helping is solving different issues with this kernel
Please let us know if we miss anyone ...oh we did already miss someone..thanks G3MOD TEAM too

What to the old thread?
Nm read that
Btw 6th post got some errors...

@Dharam, i have a question. In your v1.8 Kernel, We can change the partitions to any type we want, can't we? Because in Mumbozver's recovery, we could only use ext2/ext4/ext2.

The kernel itself supports everything, but CWM only supports EXT2. I will look into either porting CWM4 or getting 2.5 to support more systems.

getting 2.5 to support other partitions will be a better idea...coz for CWM 4 you need complete CM7 source, and also most of the update.zip's on the g3 forums use amend...and CWM 4 supports only edify....

All the best to the future process
Sent from my GT-I5800 using XDA App

Right, I want to work on USB OTG but lack the cable, and the only way I can do it with what I have is if I destroy my only USB cable for my phone. So if someone wants me to do USB OTG, then buy me a cable and I'll do it
All the stuff is there to do it, I just need to get the phone to switch into host mode.

I think v1.9 is going to come sooner than expected...excellent work by the whole team...

[KERNEL & CF-root][GB][LE4/Universal] Bam Custom Kernel: BCK beta 15 [07.02.13]

BCK - Bam Custom Kernel for i9003 / Galaxy SL
This Kernel is based on the Chinese GB source, released by Samsung on the 18th of November. Last changes to the source were made by Samsung on November 15th. If you still have questions after reading this post, look at the FAQs (including a list of requested features and known issues).
Kernel features:
No SOD
Bugfixes:
~ Sync bug fixed. Notifications for new mails and messages should arrive within one minute under all circumstances
~ Bluetooth problems fixed. Your phone now should play nice with bluetooth hosts, i.e. your car audio system
~ Micro stutters nearly completely gone thanks to lowered processor transition latency. It's smooooooooth
~ Home button double presses exterminated
Governors:
~ smartassV2 governor by erasmux (default)
~ interactive governor by Mike Chan
IO scheduler:
~ SIO IO scheduler by Miguel Boton (default)
~ BFQ IO scheduler by Paolo Valente and Fabio Checconi
~ deadline IO scheduler
Extended features:
~ ro.secure=0 (root acces through adb shell - to root the 'clean flavour' of BCK, please follow the instructions)
~ EXT4 support (to convert your file system, use amit.bagaria's ext4 add-on .apk) (Only in CF-Root .tar)
~ Support for init.d scripts (to use scripts, please follow the instructions) (Only in CF-Root .tar)
~ BLN support (to use BLN, please follow the instructions)
~ TUN support for VPN networks built-in (no module needed)
~ Increased SD-card read ahead of 768 kb for improved read speed
~ Available with universal CF-root ramdisk based on amit.bagaria's version, improved by loSconosciuto (Only in CF-Root .tar)
~ Available with universal CWM ramdisk (rooted) based on universal CF-root, but 'tweakless' (Only in CWM .tar)
Overclocking and Voltage:
~ Evolved sysfs interface for variable overclock or underclock (all operating points [OPPs] can be adjusted seperately)
~ Fifth OPP (1.2 GHz) available, device booting up at stock speed (1 GHz)
~ Total frequency control. The device will never run at higher speeds than defined by you, not even on WiFi.
~ sysfs interface for voltages (read only at the moment)
~ Slight undervolt (3%) on all OPPs
Flashing , settings and compatibility:
If you want to use BCK, please flash it on a clean stock ROM. If you want to go back to stock, repartition and reflash the full firmware with ODIN. This kernel will not work on CM or MIUI.
The CF-root and CWM versions (PDA_BCK_CF-root_universal_***.tar / PDA_BCK_CWM_universal_***.tar) can be flashed on any recent Gingerbread firmware. These versions are pre-rooted, which means they include Superuser.
The non-CF-root "clean" version (PDA_BCK_XXKPQ_***.tar / PDA_BCK_XXLE4_***.tar) will only work on XXKPQ / XXLE4. Do not flash this version on anything other ROM than the one indicated in the file name. This will break your WiFi. It's especially risky to flash the clean version of BCK after flashing any CF-root kernel before. Don't do it. This version does not include Superuser, but it is prepared to be rooted. Follow the instructions to do this.
After a kernel update, please wait for the device to boot up and reboot once. There is generally no need for cache cleaning or a full reset. To change the governor and IO scheduler, I use NoFrills CPU Control from the market. It's free and reliable.
I recommend to use the clean XXKPQ version. If you want / need to have root, try the CWM version. If you want the 'full package' with FuGu-Mod and more, use the CF-root. I recommend that you do not apply any further tweaks and use a stock ROM.
>>> Warning: Overclocking may damage your device. <<<​
Overclocking instructions:
For overclocking, you will need a shell on your phone, or adb access. I use Android Terminal Emulator. Overclocking is currently limited to certain frequencies (see below) and all operationg points will be set with the stock voltage of the corresponding stock frequency. The frequencies you set have to be within the following ranges:
Code:
OPP1: 100 - 500 MHz, stock 300 MHz
OPP2: 501 - 700 MHz, stock 600 MHz
OPP3: 701 - 900 MHz, stock 800 MHz
OPP4: 901 - 1100 MHz, stock 1000 MHz
OPP5: 1101 - 1500 MHz, stock 1200 MHz, not used by default
Remember that your phone uses all operating points depending on the current load. Anything more than 10% higher than the highest stock frequency is likely to be unstable, but you are free to try it. To change the clocks, open Terminal Emulator (or type 'adb shell') and hack in
Code:

echo "1100" > /sys/power/overclock_opp4
as an example. The others are opp5, opp3, opp2 and opp1. That's it.
Settings will be lost at reboot, unless you add them to your init.d scripts. I do not recommend this, as this may cause boot loops if the settings are to high! Be advised that NoFrills CPU Control, SetCPU, or whatever app you use that may adjust clock settings interfers with this. You may wanna update their settings after this. I do not recommend using them to set anything at boot if you overclock any OPP, because they might save the wrong frequencies and crash or do worse.
Changelog:
beta 1:
Added cpufreq governors
beta 2:
Changed smartassV2 settings to fit i9003
Added EXT4 support
Smaller zImage due to .config changes
beta 3 (not released):
Experimented with overclocking (not working, yet)
beta 4:
Finetuned smartassV2 settings
Made smartassV2 governor default
Reverted: Smaller zImage due to .config changes
Switched to linaro 4.6.2 toolchain (also used for ICS)
Activated new, aggressive compiler optimizations (-O3)
Added deadline IO scheduler
Added BFQ IO scheduler (10% higher performance than CFQ in Antutu Database IO Benchmark. This does not mean, that the maximum read or write speed increase! It just means that the throughput under heavy load is higher.)
Made BFQ IO scheduler default
Updated all modules
beta 5:
Variable overclock. Loosely based on the modifications of the Nook Color sources by dalingrin and of course with help from amit.bagaria and DooMLoRD.
beta 6:
Variable overclock for all operating points
beta 7:
Switched to universal CF-Root by amit.bagaria (BCK now should run on every recent GB ROM)
Added correct version information in settings menu, credits to DooMLoRD
Fixed cpufreq stats to correctly reflect frequency changes
Increased SD-card read ahead to 768 KBytes. This results in higher SD-card read speeds.
Major simplifications in overclocking code. Works more robust, now.
Added sysfs interface to show voltages. See /sys/power/overclock_vdd_oppX
Changed all voltages to the mainline Linux kernel defaults. This results in a slight 3% undervolt for each OPP, which saves about 5% power and should have no impact on stability whatsoever. Below you will find an overview of the exact voltages.
Code:
stock BCK
OPP1: 1.0250 V 1.0000 V
OPP2: 1.2000 V 1.1625 V
OPP3: 1.3300 V 1.3000 V
OPP4: 1.3875 V 1.3500 V
OPP5: not def. 1.3800 V
beta 8:
OPP5 (1.2 GHz) now enabled in _1200 version of kernel. Thanks to knzo for pointing me to the right patch.
Fixed video recording bug when running at 1.2 GHz
Fixed power management issues at 1.2 GHz
Small changes to smartassV2 and interactiveX settings
beta 9:
Added simple IO ('SIO') scheduler
Only one kernel version now, which includes OPP5 (1.2 GHz) but boots up at 1 GHz. Be advised that your device may nevertheless be running at 1.2 GHz for five to ten seconds at boot because of software limitations.
Changes in PM to always respect cpufreq policy limits. From now on, the device will never run at higher speeds than defined by you, not even on WiFi. Based on an omapzoom.org patch.
Changes to OPP switching code. May lead to less 'hickups'. Based on an omapzoom.org patch.
Bugfix for framebuffer code. Based on an omapzoom.org patch.
Reduced IVA / DSP frequency when on OPP5 to be on the safe side.
beta 9fix:
Reverted: Changes to OPP switching code. May lead to less 'hickups'. (Patch caused random freezes using WiFi.)
Reverted: Bugfix for framebuffer code. (Patch showed no noticeable benefits.)
beta 10:
Fix for sync bug applied. If you still have problems, please report.
This version is identical to beta 10rc14. No need to flash again, if you already are on that version.
beta 11:
Updated universal CF-Root by amit.bagaria to version 9 (released 1st of February 2012), but NO touch recovery
Slight increase in OPP5 voltage (1.38 V -> 1.40 V), may prevent some reported reboots on 1.2GHz
Code:
stock BCK
OPP5: not def. 1.4000 V
Changes in overclocking code to play nice with your frequency settings. If you overclock OPP5 but have restricted freqs to 300 - 1000 MHz, it won't automatically activate OPP5 anymore. The same is true for the lowest OPP.
If you overclock OPP4 above 1000 MHz and have restricted freqs to 300 - 1000 MHz, it will update the upper boundary to the new frequency of OPP4 so it doesn't get deactivated.
beta 12:
Fixed bluetooth problem with car audio systems (Based on omapzoom patches [1], [2] and [3]). Might resolve other bluetooth issues, too.
Universal CF-Root: Fixed bootanimation. Thanks to loSconosciuto.
Universal CF-Root: Fixed install procedure. It will check the actual kernel version, now. Thanks to loSconosciuto.
Universal CF-Root: Fixed fix_permissions script to work on our device. Thanks to loSconosciuto.
Switched to user_defconfig, to avoid unnecessary debug lines in dmesg.
beta 13:
Updated sources to GT-I9003_SWA_GB_Opensource_Update1 from the 30th of March. This also enables TUN support by default. You do not need any modules for this - it works "out of the box" with any VPN client.
Universal CF-Root: Backup is not failing anymore when started from CWM. Thanks to loSconosciuto.
Universal CF-Root: Some small improvements to multiple scripts.
Home button double press issue fixed. There should be no more unwanted double selections in CWM and you can now reliably long press the home button to bring up the list of previously used apps. Idea and timer function taken from a patch by Tegrak.
Fixed priority class for CONTENT_PROVIDER not being set, which may have caused apps of this class to be ignored by the autokiller, resulting in less free RAM.
Lowered OMAP processor transition latency to the value recommended by TI. Subjectively, this brought huge improvements in terms of reducing micro stutters.
Lowered CFS scheduler latency and granularity to values very close to mainline kernel defaults. This could reduce lags in some critical situations, but it doesn't do wonders.
Switched to SIO as default IO scheduler.
beta 14:
Universal CF-Root: Replaced CWMManager and TweakManager with zipaligned files. Thanks to loSconosciuto.
Universal CF-Root: The TweakManager is not replaced on install if it didn't change to preserve it's settings. Thanks to loSconosciuto.
Universal CF-Root: Corrected problems because of too little free space in /system when converting to ext4 by permanently moving InfoAlarm.apk from /system/app to /data/app. Thanks to loSconosciuto.
Universal CF-Root: Fixed the non-working WiFi on XXLE4 and prevented future problems. Instead of patching the WiFi modules, they are now replaced. Thanks to loSconosciuto.
Universal CF-Root: Fixed some small mistakes in the CF-root install procedure.
Switched the compression of ramdisk and kernel from gzip to lzma. This makes the files much smaller and allows us to include more 'stuff'.
Changed smartassV2 settings to wake up at lower frequencies. Further, it is not locked at 300 MHz anymore when the screen is off. Tests showed that free scaling is more battery friendly.
Removed InteractiveX and OndemandX governors and added the Interactive governor by Mike Chan (Source: CyanogenMod Crespo kernel). Since free scaling proved to be more battery friendly, the screen off profiles in InteractiveX and OndemandX made them superfluous.
The device will not scale above 1 GHz for some seconds when booting anymore. It's now safe to use BCK even if your device can't handle 1.2 GHz. Based on a patch by dalingrin.
Changes in PM to respect cpufreq policy limits when playing or recording video. The device should respect your wishes under all circumstances, now
Fixed the SmartReflex voltage calibration of the OMAP SoC for OPP5. This could lower power consumption as soon as OPP5 (1.2 GHz) is activated for the first time.
Slight increase in the OPP5 nominal voltage (1.40 V -> 1.42 V) to allow for some adjustment by SmartReflex (now that it's working...), if necessary. The actual voltage when the device is running will not change for most users! Based on patches by dalingrin and Sanjeev Premi.
Code:
stock BCK
OPP5: not def. 1.4200 V
beta 14 fix:
Universal CF-Root: Fixed the non-ending row of force closes after flashing the Universal flavour of BCK. The clean XXKPQ version did not show these problems and didn't need a 'fix'.
beta 15:
Universal CF-Root: Modified some permissions to bring it closer to the stock ramdisk
Universal CWM: Created a CWM ramdisk based on CF-root, without most tweaks. You now have three BCK flavours to choose from
Updated to newest UPDATE2 sources by Samsung
Sync bug fix reworked to use new Samsung method from UPDATE2. This may lead to slightly lower standby battery consumption.
Fixed accidental front camera mirroring
Editing smartassV2 settings with busybox 1.20.x and newer no longer leads to reboots. Thanks to loSconosciuto for pointing me to the patch.
Fixed complete crash of WiFi driver when activating WiFi by adapting smartassv2 thresholds
Reverted to the original Google Android toolchain using gcc 4.4.3
Because of the toolchain-switch, the compiler optimizations are now back to -O2 instead of -O3

it doesnt have oc ! it has special cpu governors which are efficient and fast

tough luck for me mate....
i compile a vanilla kernel which is ~200 kb larger than stock zImage and it doesnt even boot!
also,even i want to update to 2.6.35.14,,,,,,,,,,,,,,how u did it without source?
also(2)lz open an acc. on github!

@sakindia123: Take a look here, update your sources to the new version, and get the new toolchain they use (see readme in the sources).

i followed that link before......
ok i will try with new source

what will happen if we use this ? are there any good feautures ?

it has special cpu governors which are efficient and fast

Now just wait for some days guys. Doomlord, bam, sakindia will show u real power of our device.

This is great! Just one little question, you said this is for a chinese firmware, but you mention KPQ, so it can be put in XXKPQ or not? Anyway sorry for my noob question

It is based on the Chinese source - this includes kernel and android system source. But the kernel is universal (not language specific), and I applied all necessary settings for XXKPQ. Therefore you can flash it on KPQ.

what does a kernel do??
it is the main driving force of a phone that i know.
does it make our phone fast??
how to flash it as i would like to give it a try right away!!
can i roll back to stock kernel after this??
sorry for thr noob question as im new to all this.
---------- Post added at 08:45 PM ---------- Previous post was at 08:40 PM ----------
also do we need to have CWM recovery for this????
or we can do it with the stock recovery menu??

i was just doing some testing and the kernel is stuck at "SAMSUNG" bootanimation after a FRESH FLASH...
any idea?
used on XXKPQ FW

I flash your kernel. From last 5hours no SOD ISSUE. I'm using smartass v2 let's see how will battery I will get from it.

Fresh flash of what PDA? Yours, mine, GitHub?
@manrock111: smartassv2 gives me slightly higher battery usage than stock. I want to tweak it, but have problems with my sources at the moment.

Log Test 9:
- Fix USB Tethering (need change dnsmasq_dhcp patch & make run dnsmasq_dhcp when USB Tethering running)
- Fix segment fault when zipalign script execute
- Add dnsc binary to ping url address and this binary function to know when you online or not. If you online crossbreeder script run/execute
- Remove sqlite3 and system server binary (not stable and broken something)
- Change value of scripts
**) For flash this need clean rom and this kernel CAN'T update from previously kernel. If you have issue with wifi tether, you can use app Barnacle Wifi Tether from play store.
Recommend kernel and everything look like stable for me. May be this final version if i don't found any bugs again
Log Test 8:
- Fix dnsmasq dhcp only need 1 process and previously version i got trouble connection issue while tethering
- Change path dnsmasq_dhcp binary to crossbreeder folder (from /system/bin/* change to /system/etc/CrossBreeder/*)
- Fix Clean Dalvik script and now work with schedule
- Add dalvikvm binary and system_server binary from jellybean (may be can boost performance)
- Use some value of tweak from ThunderBolt/Pikachu01

**) For flash this need clean rom and this kernel CAN'T update from previously kernel. If you have issue with wifi tether, you can use app Barnacle Wifi Tether from play store.
Log Test 7:
- Fix crossbreeder (low RAM because duplicate dnrd process and dnsmasq_dhcp process. Fix in this version)
- Fix haveged script (need link /dev/random to /dev/urandom). Entropy always stay in 4096. To check this you can type in terminal emulator
Code:
su
entro
- Remove extendedmenu and rngd
- Use only two dnsmasq_dhcp/dnsmasq process. If you check in terminal emulator with
Code:
su
ps | pgrep dnsmasq_dhcp
or
Code:
su
ps | pgrep dnsmasq
You'll found only 2 process running and always got 2 dnsmasq process everytime (in other version you'll get many dnsmasq and make low RAM).
- Fix build.prop tweak
**) For flash this need clean rom and this kernel CAN'T update from previously kernel. If you have issue with wifi tether, you can use app Barnacle Wifi Tether from play store.
Log Test 6:

Log Test 5:
- Fix script init.d
- Fix Crossbreeder more better and less aggressive to check DNS and IP Address
- Fix hosts and save more memory
**) For flash this need clean rom and this kernel CAN update from previously kernel test 4. If you have issue with wifi tether, you can use app Barnacle Wifi Tether from play store
Log Test 4:
- Use GCC 4.4.3 to compiler kernel (much more stable)
- Remove unnecessary module
- Add random optimize in kernel (3 commit github)
- Remove haveged and use rngd
- Combine crond script to one script and run every 45 minutes. Save more ram for this (script are Fast Engine Flush, Fast Engine Swap and Reduce Wifi TX Power)
- Add script Read Write Partition tweak and I/O Scheduler Tweak
- Update CrossBreeder. Much more save ram and now use blank gif for ADBlock (every things work).
- Boot more faster than before (optimize script more efficient) and more performance
**) For flash this need clean rom and can't update from previously kernel test (a lot of difference things)
Log Test 3:
- Fix All CPU Governors source code (i hope it)
- Try with difference egl.cfg value
- Change Fast Engine Flush script run every 60 minutes
- Change Fast Engine Swap script run every 45 minutes
- Change Haveged script run every 20 minutes
- Add Reduce TX Power script and this script run 30 minutes after you turn on your wifi/wifi tethering

FAQ
How to know my script in init.d work?
You can see all log in /data/*.log
Why first boot so long?
Be patient. Because 3 script do it a job first time (SQLite database vaccum Script, Automatic ZipAlign Script and Clean Dalvik Cache and Cache Script).
The second boot will fast.
How to know rngd or haveged run?
You can type in terminal
Code:
su
extendedmenu
How to make/create Odexed framework file?
You can type in terminal, use adb or qtadb
Code:
su
dexo
And your phone will reboot if the script finish do a job
How to know CrossBreeder AdBlock work?
You can try to view file /system/etc/hosts and try one url in that file. Try it in your internet browser and you can get [ADBLOCK] (in NEW VERSION you'll got blank gif).
Can I disable ADBLOCK CrossBreeder?
Yes, you can. Try to enable or disable with huawei extended menu or use AdAway apps to disable hosts file and reboot to see result
Can I enable or disable feature of this all tweaks?
Yes, you can. Try to enable or disable with huawei extended menu

You should probably provide a link to your kernel source.

In plain language
DO NOT STEAL MY SH*T !!
UpInTheAir is NOT responsible, the person you see in the mirror is !!
REQUIREMENTS:
Supported variant only !!
Touch Wiz Android M 6.0.1 ROM or UX leaked firmware (beta support)
Appropriate custom recovery (i.e..TWRP for your variant)
INSTALLATION & UPDATE:
If you have Synapse installed = = you must clear Synapse app data before flash !!
Device Settings: Enable Developer Options > OEM UNLOCK is ENABLED
Boot into custom recovery (volume UP + home + power)
DO NOTHING but flash SkyHigh kernel.zip (ALWAYS flash again AFTER any custom ROM installation, system or data wipe)
After flash == DO NOTHING but REBOOT IMMEDIATELY from TWRP or you will have to re-flash !!
CONVERT EXT4 TO F2FS FS:
If not already, install the latest TWRP for your device variant (ie. 3.0.2-2). This must support F2FS.
Boot into TWRP.
Insert USB-OTG
** ALL DATA WILL BE WIPED FROM INTERNAL STORAGE (restored later)
Backup (copy) all important files (incl. your NANDROID) off device (ie. from internal storage > USB STORAGE). This can take a while. Advanced > File Manager > .....
Home > Backup > Select Storage > USB Storage > OK > "Swipe to Backup" (Only need DATA, but recommend to backup all partitions).
Install > Select Storage > USB Storage > OK.
Select f2fs.zip > "Swipe to confirm flash" (This will WIPE ALL DATA !! & convert DATA & CACHE to F2FS. System is not supported by kernel).
Check the box to remember setting and “Swipe to allow Modifications”.
If you do not have Step #8, then Data was not converted to F2FS.
Mounts > unchecked both Cache & Data. Repeat Step #7 & 8.
Restore > Select Storage > USB Storage > OK > Select TWRP Backup folder > DATA ONLY !! > "Swipe to Restore" (ignore warning about EXT4).
Home > Install > Select Skyhigh_kernel.zip > "Swipe to confirm Flash".
Home > Mount > USB STORAGE > uncheck/unmount (then remove USB-OTG).
Home > Reboot > SYSTEM.
Wait ~2-5 mins for boot.
Once booted, let stabilize for ~5 mins.
You can check Data & Cache F2FS FS status in either /proc/mounts or Synapse app (FS section).
Use a root type explorer (su permission) & navigate to /sdcard, and delete the "0" folder.
Move (copy) your backed up files from Step #4 to internal storage (/sdcard). This can take a while. Maybe one folder at a time is better?
ISSUES ?
If using TWRP MTP mode, deleting some folders/files may crash TWRP and cause corruption. Instead, use a root type file explorer to delete from device.
If you need to wipe data, then use the ext4 or f2fs.zip, otherwise this is not possible with this TWRP !!
Not tested any method with customized ROMs. The ROM installer script may re-format partitions back to EXT4 or not mount correctly causing TWRP crash or corruption. I can only suggest to Flash ROM with EXT4 FS > make a NANDROID on USB-OTG and then follow the F2FS steps above.
CONVERT F2FS TO EXT4 FS:
The Same steps as above, but use the ext4.zip !!
OPTIONAL SYNAPSE INSTALLATION:
After boot:
Wait at least 120 secs to stabilize
Install Synapse app from Google Play and rate it ☆☆☆☆☆ !!
Open Synapse
Tap "Understood"
So changes stick every time you start Synapse == Make any change & 'apply'.
Recommend: Disable KNOX with Synapse
DOWNLOADS:
** I will NEVER support KOREAN (S/K/L) variant. Get over it and flash ARTER kernel instead !! **
Mod Edit: Link removed.
BUGS:
Aroma Installer: 10% of installation will encounter Aroma installer "freeze". It's only the display that freeze, the script still execute in the background. Just wait a minute, then press slightly to the top right 'home' key / top left of the 'back' key . . .

FAQ & HELP
TROUBLESHOOTING GUIDE:
I might not have your device variant and or able to reproduce your "issue".
Please provide as much information as possible.
Without resetting your device to a stable unmodified baseline, any potential troubleshooting or logs could be meaningless.
So please follow the guidelines set out below. Users can't "read minds".
Without providing important information, we are unable to help YOU.
Search thread, XDA and Google before posting
Provide as much information as possible.
- Device model
- Firmware version
- ROM name / version
- Kernel version
- Modem version
- Bootloader version
- Synapse settings (try default)
- Installed tweaks and apps etc (Xposed ?)
- The exact steps you've taken to try resolve the issue yourself.​
Exact steps to reproduce the issue. Provide screenshots if able.
Does it work with older / other versions etc
Reset your device to a stable baseline (ie. stock) with only custom TWRP recovery and kernel (FULL WIPE: system, cache, dalvik-ART)
Possible logs
FAQ & HELP:
CAN I BUILD A KERNEL FOR YOUR __XX DEVICE ?
Sorry. I don't have the spare time for any more variant support.
Additionally, I do not build for any device that I can not compile using SAME source, personally test method or debug. Some device variants can compile with same source.
CAN I INCLUDE SkyHigh KERNEL IN MY ROM
NO == My ramdisk modifications are COPYRIGHT (refer LICENSE in Post #2), and distribution without MY (UpInTheAir) prior written consent is not only in a breach of that license, but also XDA Rule #12)
Although I do appreciate your contribution, if you could please do not include my kernel in any ROM package etc. This policy goes for anyone.
Having my kernel distributed outside my development thread just removes a lot of credit and more importantly, constructive user feedback that could be helpful to my development or user issue.
ALWAYS on DISPLAY (AoD)
I have spent some time to attempt port S7 display drivers to our kernel, but haven't had success as yet with too many errors.
TBH, it's a lot of work for something I'm not really interested in or would use. . . so I don't wish to spend any more of my own time on it, sorry. If someone else does it, GREAT
DO I "NEED" SYNAPSE
THERE IS NO "NEED" !!
It is "recommended", which is OPTIONAL, and not "needed".
It is for ADVANCED or adventurous users who wish more control of their device or use various features I've added.
Using any other optional tweaking or control app may conflict & many features and options won't be available.
WHY WAIT 120 SECS
The kernel and Synapse scripts need time to boot up properly and allow SU permission.
There are scripts / code that have a deliberate delay and must run after Synapse. These are not user optional.
Synapse has a stability check on boot. You may get "synapse boot cancelled".
Thermal throttling will be trying to limit many things, let the device settle
OTHER PARTY CAN NOT HEAR VOICE ON SPEAKER PHONE
It could be a conflict in the system/etc/mixer_*.xml. I don't know for sure, but if I exclude the sound mod, then this "fixes" the problem.
As I cannot reproduce the issue (and the majority), then the audio mod stays.
Unfortunately, making it optional would require to build kernels without and create much more work for many device I don't actually use.
Either live with it, or use another kernel. Sorry.
"NO UCI SUPPORT"
It's a ROM busybox compatibility issue !!
Re-flash kernel as per Installation Instructions. (kernel install zip flashes proven busybox binary to /system/xbin)
BACKUP / RESTORE ISSUES
It's a ROM busybox or sqlite3 compatibility issue !!
Re-flash kernel as per Installation Instructions. (kernel install zip flashes proven busybox binary to /system/xbin)
BACKUP & RESTORE
DO NOT restore profiles from different kernel version
Refer to THIS post for "how-to" screen-shots
Refer to THIS post for a "how-to" video
LOADABLE MODULES AREN'T WORKING
Check your /system/lib/modules directory. Are any ____.ko present?
Did you flash a ROM or wipe the system partition at any point? Doing this will remove them !
Re-flash the kernel will install the modules.
If modules aren't installed after flash, then re-flash and manually mount system in recovery first.
You can check running modules in terminal with:
​lsmod

F2FS SUPPORT
It's not needed. You wouldn't see any difference or measure much, if anything. Not worth the potential trade-off. This is not eMMC anymore
Storage Benchmarks
STUCK ON SAMSUNG BOOT LOGO AFTER FLASH
Ensure you flashed the correct kernel for your device model
Ensure your download is not corrupted. Check MD5 hash or re-download
Your current base firmware (ROM, boot-loader version etc.) may be incompatible - UPDATE to latest with Odin and try again.

BATTERY TIPS (require updating !! )
Try some (or combination) of the CPU MULTICORE features in Synapse:
HMP profile = Default (values are battery orientated)
Power Aware Scheduling (slight performance cost) = Enabled
HMP LITTLE Packing (slight performance cost) = Enabled
PEWQ (power-efficient workqueue) (slight performance cost) = Enabled
Set A57 & A53 Interactive governor profile = Battery
Set Input-Booster for key/touchkey profile = Battery
Multi-tasking: enable UKSM & "low" or "quiet" profile (slight performance/battery cost)
PERFORMANCE TIPS (requires updating !! )
Set A57 & A53 Interactive governor profile = Performance
Set A57 & A53 Interactive governor = Turbo Mode (battery cost)
Set HMP threshold profiles = Stock or Performance
Once in a while:
Optimize Databases
FSTrim​
RANDOM REBOOT
Don't UV or UC CPU or GPU
Use SkyHigh defaults
Use a stock UNMODIFIED ROM for your device variant
No tweaks, Xposed or other CPU control apps installed
Follow the TROUBLESHOOTING GUIDE
ASV_GROUP (ALL DEVICES ARE NOT CREATED EQUAL)
THIS is an example from my Exynos5420 source. Similar idea for Exynos4
DOWNLOAD LINK NOT WORKING
I want to keep this project all in one place - ☆☆ NO MIRRORS ☆☆
Please try again in a few minutes
POOR CPU/GPU BENCHMARK or GRAPHICS PERFORMANCE
Disable any CPU MULTICORE options in Synapse
Disable any Battery profiles in Synapse. Set to default or Performance.
Allow the device to cool. Repetitive testing will heat the device hardware and invoke thermal throttling and lead to decreased benchmark.
HIGH CPU/GPU OC == excessive heat == thermal throttling == reduced clock frequency == DECREASE PERFORMANCE
DYNAMIC MANAGEMENT OF DIRTY PAGE WRITEBACKS
by Christopher83
This feature allows to have two different intervals for dirty page writebacks and to dynamically manage them when the system has been resumed (it's active) or when has been suspended.
Three new procfs parameters are exposed inside /proc/sys/vm path:
dynamic_dirty_writeback is the activation status of this feature, set 1 to enable it, set 0 to disable it and use the standard behaviour
dirty_writeback_active_centisecs is the interval for the dirty page writebacks when the system is active (screen on)
dirty_writeback_suspend_centisecs is the interval for the dirty page writebacks when the system is suspended (screen off)
This feature is in part inspired on Francisco Franco's PATCH
TCP/IP NETWORK SECURITY
Thanks to zeppelinrox & V6SuperCharger
Hardening the TCP/IP stack to SYN attack

CHROMECAST - STREAMING PROBLEMS
Lock screen MUST be enabled (simple screen lock swipe) I don't know why but it breaks the chromecast app's ability to resume smoothly if switched off
Synapse > Network > DTIM (both screen ON & OFF) = 1
Synapse > Network > WIFI Power Mode (screen OFF) = FAST

@UpInTheAir needed to create these threads to compile them for Synapse. He contacted me to close these as soon as he made them until he is ready with the finished product. Have patience.
Also I would like to apologize to UITA as the last ban may have been due to a system glitch where the signature was restored upon return, so was unjust. I have seen these glitches before and better communication might have prevented the error. We will do better going forward!

SkyHigh KERNEL REBORN - v5.6 released !!
SkyHigh KERNEL REBORN - v5.6 released !!
Hi fellow members.
Please find my latest release for SkyHigh kernel. There are many many changes, both visually (more / improved features) and a upgraded engine (better performance & efficiency) since I last publicly released. Far too many to talk about. . . .
And no - it DOES NOT fix call audio issue with leaked UX ROM. I believe it to be a ROM issue n!
Please note that although I have taken as much care in building and testing by my friends and I, the kernel may still not perform as hoped for you. Could be due to various factors including (but limited to):
hardware quality
firmware installed (incompatibility)
user habit (how you use the device)
apps & mods installed, customization's (conflicts)
user kernel settings (read them carefully - if in doubt == defaults)
As noted in Post #3, I may not have your device variant and not be always able to help either. In the end, sometimes SkyHigh is just not meant for you . . . .
If you have issues = = READ & FOLLOW ALL Posts #1-3
READ & FOLLOW THE INSTALLATION INSTALLATIONS EXACTLY (or else device will not boot)
Also please note (as per OP) the support for UX based ROMS is still in beta. I have personally tested very briefly, and also some of my friends (not all variant)
Enjoy
UITA

BUG Report Update: UX firmware Bluelight Filter
The blue-light issue is in kernel source.
Compiled & flash SkyHigh + stock ramdisk + stock dt.img == no blue-light

I see your posts in various development threads. . .
From your history, seems you're never happy with anything.. .
THREE options:
1. Read and follow what's requested of YOU top of Post #3.
2. Use a different kernel
3. Use stock

Anyone using a Grace UX rom with this kernel and if so can you link me one that's working? Been wanting to try it out.
