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/roms/rom4_ROM");
//Data + sd-ext Backup Dir
__system("mkdir /sdcard/Android/data/g3mod/data/Froyo_DATA");
__system("mkdir /sdcard/Android/data/g3mod/data/CM6_DATA");
__system("mkdir /sdcard/Android/data/g3mod/data/CM7_DATA");
//Kernel dir
__system("mkdir /sdcard/Android/data/g3mod/kernel/Froyo");
__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.

Click to expand...

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...

[ROM][STAR N9500][4.2.1] King Rom 3.0 Evolution

King Rom 3.0 Evolution
This is the version to install from CWM recovery
valid for all models of Star N9500​
The problem with Lcd and Camera drivers will never be a problem. First in the world I solved the problem.
You only need to know before installing what is the combination of LCD driver - camera of your mobile phone. Know that during the setup wizard, the installer will ask you what is your driver combination.
Links to everything that is required for proper installation can be found in the following paragraphs.
An introduction is due​If you are looking for a Rom that only changes the look and feel of the phone, which has a nice logo Samsung, or other (which I think is really pathetic), or having many beautiful colorful icons and also some beautiful 3D effects and maybe even makes a good coffee… then don't download my Rom is not for you!
But if you are looking for fluidity and speed, if you want a gps fix in a few seconds, if you want a wi fi stable and fast, if you want the best performance from your phone, then download it, this is your Rom!!​

Introduction to the installation of the King Rom 3.0 Evolution​
Before installing the Rom you need to make a backup of your device in case something goes wrong. Do it with MTKDroidTools flashabile with FlashTool.
Those who have already installed the recovery Cwm they can make a second directly from recovery.
For the first, here is a guide to the procedure of backup, for the latest version of MTKDroidTools and drivers necessary for the proper use of the application Backup with MtkDroid
Just this already, but if you want here is the guide for the second procedure to install the modified recovery Cwm How to install Cwm

Installation Guide
King Rom 3.0 Evolution
through Cwm recovery​
Link to download the King Rom 3.0 Evolution version for CWM recovery:​King Rom 3.0 Cwm version
See here​
Before installing the Rom is necessary that you know what version of drivers Lcd and Camera is on your device, because the installation with incompatible drivers would inevitably lead the phone to the brick. During the installation process, my Touch Installer you will propose different combinations of drivers Lcd and Camera. Simply indicate which is the your, and the installer will continue its task.
If you do not know what is the drivers combination of your device, you can check it through this easy steps:
Open the numeric keypad of the phone (as if you have to dial a phone number)
Enter the combination * # * # 116 # * # *
A window will open which among the many things listed, will also present the version of your Camera and Lcd drivers.
If this procedure does not work (does not work on all versions of this device) then you just enter in "Factory Mode":
Turn off your phone
Holding down the volume down button (be careful! Volume -), press the power
As soon as the phone is starting, you can leave the power button whilst continuing to hold down the volume button -
It will open a window with the words "factory mode" followed by one with various items, as in this example
You can leave the volume button
Now the volume button will need for scroll through the menu items
Go to "version" and enter by pressing the home button (middle bottom)
Now between the various items that appear on the screen there will also be those of your camera and LCD drivers (if you do not see scroll with the volume key that are below)
Now we are ready to install the King Rom​
You may have already downloaded the zip file from the link above and copied the zip file in SD card.
Restart your device in Cwm recovery and make a backup of your device.
Then always from Cwm perform a full wipe:
-> Wipe data / factory reset
-> Wipe cache partition
-> Advanced -> Wipe Dalvik Cache
-> Advanced -> Wipe Battery Stats
-> Mounts and storage -> format system
-> Mounts and storage -> format EMMC
to make sure you have no problems!
You are ready to install the King Rom from Cwm with the usual:
-> Install zip from sdcard.
Will start the installation process with the touch controls. Be guided by the Touch Installer and when will be asked what is yours drivers combination, simply indicate which is the your from those listed, and the installer will complete the installation.
At the end of this at the request of the installer confirm that you want to reboot into CWM recovery and from here again:
-> Wipe cache partition
-> Advanced -> Wipe Dalvik Cache
Reboot and enjoy your new King Rom!
Enjoy my work. It's really powerful and optimized. Enjoy!!

*/
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

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

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

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

It turns out to be the google DNS causing the problem. I forgot L Speed was applying the google dns as well. Sorry for being wasting your time. Thanks for the support ! the kernel is smooth and the battery last longer. I can send you the latest boot.img if you still want it.

When in Aroma, please DELETE all that interfering BS init.d 'tweaks' that are not optimised for our device. Those that come with SkyHigh are !!
Don't worry about boot.img thanks.

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.

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

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

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!

Me likey. Up in the Air can't wait to have you back!

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. . . .
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 Filte
The blue-light issue is in kernel source.
Compiled & flash SkyHigh + stock ramdisk + stock dt.img == no blue-light
Compiled & flash SkyHigh + stock ramdisk (with permission edits) + stock dt.img == no blue-light
Compiled & flash SkyHigh + UX ramdisk + stock dt.img == no blue-light
Compiled & flash SkyHigh + UX ramdisk + UX dt.img == no blue-light
Which all points to the source I’m using . . . and nothing I can do about it. That's leaked firmware and no proper source, what else to expect. . . .

Good to see you back! Been running v5.6 since early yesterday and it has held up great.
Out of curiosity, I flashed a UX based ROM along with SkyHigh and it booted up. No data since it was for another variant (even though it was claimed that it works for Sprint). Just wanted to report that it was booting for UX.

Nice. Haven't BLIND build for anyone to test for Sprint as so much development has gone on since.
Some variant can be incompatible due to firmware issues, and indeed individual devices too. For example, had to remove the adaptive touchkey and brightness mods for a friends N9208 to remain stable.

YES! You're back!!!
Been running now for 4 hours without any issues. If something wonky happens, I'll get logs.

Well extra props to you for being able to pull this off blind! Maybe somebody smarter than me can port one of the UX ROMs so we can really give it a test.

Oh, I just meant that the only problem that I found was that I had a no SIM error. I wasn't trying to imply that it was kernel related. More so that the problem was that I was flashing a ROM built for the international variants. From what I could tell, your 920P kernel was running well on UX.

That could be anything. But, most likely due to incompatible ROM same as the T/W8 and not the kernel. Some ramdisk permissions may have changed though.

Up In The Air,
I am loving this new kernel and all the great functions with synapse. My battery is finally lasting 2 days with moderate use. Thanks for coming back and for all your hard work it is greatly appreciated.

Been running this since I got my N5, loving it dude, fantastic work sir... :good:

Thanks for this man. I was just commenting on telegram the other night about the level of reading comprehension and being lucky we have the devs we do for the N920p.
Some people do still read and appreciate the work. :good:
