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 !!
​** I will NEVER support KOREAN (S/K/L) variant. Get over it and flash ARTER kernel instead !! **
Touch Wiz Android M 6.0.1 ROM or UX leaked firmware (boot support only)
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 . . .
UX BETA firmware - blue light filter
UX BETA firmware - torch light (some ROMs)
HD voice ? - Speakerphone: other party cannot hear voice

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.
** I will NEVER support KOREAN (S/K/L) variant. Get over it and flash ARTER kernel instead !! **
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
KTOONSERVATIVE GOVERNOR
Some info from the author HERE
DT2W & COLOUR CONTROL
No, I cannot make it work properly with single source for all supported variants
CPU POWER CONSUMPTION
The Samsung Exynos 7420 Deep Dive - Inside A Modern 14nm SoC (by ANANDTECH - Andrei)
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
Bump up tw_buckets in case we get DoS'd
Ignore pings
Don't cache connection metrics from previous connection
Don't pass traffic between networks or act as a router
Enable spoofing protection (turn on reverse packet filtering)
Don't accept source routing
Don't accept redirects

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. . . .
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

I don't know if it's a bug, On the first attempt I tried to boot on Enforcing but didn't boot, at the Samsung logo it vibrated consequtively, bzz, bzz .... bzz, bzz like. But Permissive works fine. I am fully operational besides Blue Filter not working.

Might be to do with UX or your ROM. I only test that on 100% stock ROM and worked fine at the time.
The blue light filter bug for UX is known and has already been reported / added to the "BUG REPORT" tab. (View in website mode on PC).
Please be aware that I extensively test only on stable stock firmware. Not beta leaks etc. So some UX bugs may or may not get fixed. I personally use stock.
