[Q] Build.prop please help

i just tried to add
Code:
windowsmgr.max_events_per_sec=26
into my build.prop using flashtool
i rebooted and got stuck at the SE logo
ok, so trying to fix this i rebooted into recovery and mounted the sd card
i copied the system.img out of my backup and extracted it using wunyaffs
undid the changes in my build.prop.
repackaged as a .zip and used recovery to flash the build.prop back...
and it still gets stuck.
what am i doing wrong ?
*EDIT*
damn... i posted this in the wrong forum... sorry
it was meant for Q&A not General :\ mybad

here is my current build.prop

i am... was... running freeX10 beta4

I didn`t see any error on your build.prop file.
You just add that line? Cause i don`t see it on your build.prop file
I just wonder why that value so low...

oh i removed the line then posed sorry
apparently 26 is optimum
i just thought id try it and now it doesnt boot.
and, stupid me, i should have backed up before changing the file but ... i didnt think it would break it :\

by adding just that line that won`t happen. i`m sure that`s not the cause!
if you just add that. i add so many things...
witch flashtool you use? the last one or 26th?
i didn`t have time to try last myself so do know if there`s any issue regarding that but i doubt

oh dear
i just realised what my problem is
when i made the changes to the build.prop i used FlashTool. waiting for a reply now i was reading your FlashTool Guide and read the bit about JIT, clicking the optimise button and saw the BIG RED TEXT
"PLEASE DON`T USE JIT OPTION THIS WILL MAKE YOUR PHONE STUCK ON BOOT!!!"
guess what i remember clicking
is there anyway to fix this ?
Btw about that number for build.prop. heres where i got that info
http://forum.xda-developers.com/showthread.php?t=881778 posts 5-8

So i presume that you've done that on 26th version.
Download the last one and run optimize cause it was one of the upgrades.
if that wont help your only option is reflash.

yeah 0.2.6... wow i cant believe i did that.
ill try 0.2.7 now.
also... thankyou for your quick replys

0.2.7 is downloading now.
but umm... if my x10 is stuck at the se logo im not going to be able to connect to it over adb will i?

even if you`re stuck you probably get some functions

ok i just tried it
this is what i got
10/042/2011 23:42:23 - ERROR - Cannot identify your device. Found lin while expecting X10, E10, U20 or E15 (read from ro.product.model from build.prop)

it doesnt give root permission

try press ask root permition
if you can`t do anything or only option is reflash i guess

yeah when i press ask for root perms the phone denies it
i guess its a reflash then ay ?

Click to expand...
Click to collapse
the phone denies?! he`s got own life?
didn`t appear to choose yes or no on the phone?
if not...reflash

hahah unfortunatly
no theres no dialog or anything on the screen to ask for root. it just denies it
i have one other idea. get the files that flashtool changes when you click optimise.
repackage them in a .zip and use the recovery console to update them
your opinion ?

don`t believe but...try

nope, not working. thanks for all your help
i will reflash tomorrow its late here

How to install/unistall?
Just flash from recovery. If you can't boot the kernel (invalid size) you probably have installed some other stuff that put kernels in /boot. Currently we are limited to 30MB on that partition, so the kernel could not be written completely. From recovery, mount /boot and just do:
Code:
adb shell rm /boot/uImage.CyanogenMod
From booted CM-Stock kernel do:
Code:
adb shell
mount -o remount,rw /boot
rm /boot/uImage.CyanogenMod
Then flash the kernel again from recovery.
This will delete the original stock cm9 kernel and make room for Bricked.
This is, per default, installed as an additional kernel, so your cm9 default kernel will still be there as a fallback.
However it will automatically be set as the default boot option.
If you want to boot into the cm9 kernel for just one time, just choose it. Though wifi will be broken because the modules differ. (pushing the cm9 modules will fix that but break Bricked wifi , how that is done is written a few lines down)
If you want to permanently fallback to the CM9 Kernel for whatever reasons, just extract the ar6000.ko from the cm9 install zip (/system/lib/modules) and do this:
Code:
adb shell
mount -o remount,rw /boot
echo "CyanogenMod" > /boot/moboot.default
mount -o remount,rw /system
exit
adb push C:\path\to\the\cm9\ar6000.ko /system/lib/modules/ar6000.ko
adb reboot
This should set the default kernel as default bootoption, as well as replace the Bricked-Wifi-Module with the original cm9 one.
If you had previously removed the CM Stock kernel, extract it from the latest cm update and add this line before adb reboot in the above list:
Code:
adb push C:\path\to\the\cm9\uImage.CyanogenMod /boot
If you want to completely remove bricked, add
Code:
rm /boot/uImage.CM_Bricked-Kernel
before the 'exit' line above.

Thank you, good catch! it's 7:45am here and I was awake all night doing stuff for the tp and for the sensation so I guess this mistake can be forgiven

remove post.

Probably a dumb question, but is the kernel backed up in a nandroid backup? Incase we run into a problem? I have a feeling it is, just wanna be sure.

I think nandroid does a backup of /boot.
But even if not it is installed as an additional kernel and set as default, should you run into any problem, just choose the default Cynogenmod kernel from moboot and push the ar6000.ko from cyanogenmod9 (zip file) to /system/lib/modules

I see it says shooter in the near future...

is it me or does this kernel @ 1.5 have better/smoother app transition than the default kernel at 1.7?
have have had a few forced reboots that i wasnt experiencing with the cm kernel though. I don't know if it's the new gapps i installed or the this kernel.. will post back after a few hours.

Back to the old kernel for now. It seems a tad slower to me. Is battery life better or worst?

There are only a bunch of compile fixups, clock+voltage changes and cleanups present which differs this kernel from the cm9 one. I am also prefering ondemand over conservative as a governor.
The real stuff will be done once I got some sleep, like fixing the pagefaults that are forcing reboots on our devices with both kernels (since this is based on cm9, it has all it's pros and cons). It is at this moment not possible that this is noticeable slower or faster than cm9, nor that it reboots more often
Benchmarks may be better due to the L2 Boost, which is not relevant for me.
All issues you are experiencing (if present with cm9 default kernel or not) should be reported to the issue tracker with as much information as humanly possible

not using OC app. so default at 1.5GHz. sitting idle, it auto reboots. i need my tablet the today so back to the CM kernel for now. Thanks for the info show-p! i'll be back here when you update the kernel.

You will still experience reboots now and then, deactivating "force 2D rendering" seems to significantly decrease the amount. But it still will happen

Awww YEee good to see showp up in here! love your kernels for the sensation!

[Kernel][01/03/2013] CoCore 4.1

This custom kernel is base on diego-ch's TWRP kernel.
I call it CoCore.
( Responsibility )
I'M IN NO WAY RESPONSIBLE OF ANY DAMAGE CAUSED BY USING THIS CUSTOM KERNEL.
( Compatibility )
This kernel works well on i9070.
I am sorry that it causes high cpu load on i9070P!
( What is needed )
* An I9070 (Andorid 2.3.6)
* Some Android experience
* Know some knowledge of how to use Android Terminal
* More patience
( Features )
TWRP Recovery 2.2.1
28 CPU Governers
8 I/O Schedulers
IO Unlocked (increased a bit speed)
Init.d Script
Custom Bootanimation
Deeper Sleep Mode
zRAM, SWAP Supported
NTFS(Read Only)
CIFS
ARM ThumbEE
ARM VFP with neon
Optimized RWSEM Algorithm
Mali GPU Tweakes/Controls
LZO Kernel Compression ( for faster boot )
Removed Useless Drivers ( for faster boot )
SLUB Memory Allocator
Automatic readahead cache size
Audio Boost*
Linaro GCC Toolchain
And many miscellaneous tweaks, it's hard to make a list for them.
Maybe i also forgot them.
A ton of new features in my updates,please Check the updated version.( See below )
( Detailed explanation )
CPU Governers Supported:
Code:
Performance, OnDemand(default), Lionheart, Powersave, Userspace,
Conservation, OndemandX, SmartassV2, Interactive, Scary, Sakuractive,
PegasusQ, Intellidemand, Lazy, Wheatley, HotPlug,
SmartAss, LagFree, BrazilianWax, InteractiveX, MinMax, SavagedZen,
Aggressive, AggressiveX, Gallimaufry, GallimaufryX, AbyssPlug, Skywalker
* To get stable scores, please use Performance to run benchmarks.
* For daily using, i recommend PegasusQ.
* Please test the governors by yourself.
* And the PegasusQ will hotplug the second cpu when screen turns off,that might cause music skip when system load is heavy.
* If unsure,please use ondemand(default)
IO Schedulers Supported:
Code:
NOOP, Deadline, CFQ, BFQ(default), SIO, VR, anticipatory, ZEN
* To get more information about governers/io schedulers, here:
http://forum.xda-developers.com/showthread.php?t=1369817
* For daily using, i recommend SIO/BFQ/ZEN
* Please choose a best io scheduler by yourself.
Init.d Script:
* Please make sure there is a latest busybox in your system.I found that init.d didn't work properly on some devices which have old version busybox.
* The init.d folder (/system/etc/init.d) must have 0755 permissions.
* If the scripts dont have execution permissions,it wont be execute automatically.
Custom Bootanimation:
* Please put the bootanimation.zip in /system/media with right permissions(0644).
* If there isn't any custom bootanimation, kernel will load Samsung official bootanimation.
DeepSleep Mode:
* Default mode is State4, i changed it to State5. Increased standby life time.
* If you use a hotplug governor,it might be unstable when you use the deepest sleep mode.
* Some users reported that ondemand works well with deepest sleep mode.
* If you mind the standby time of the phone,please give it a try.
* You can get information about CPU sleep states:
Code:
cat /d/cpuidle/stats
* To change the allowed deepest sleep mode: (e.g. Allow State6)
Code:
#echo 6 > /d/cpuidle/deepest_state
zRAM & SWAP:
* zRAM must be enabled by script/command.
Code:
mkswap /dev/block/zram0
swapon /dev/block/zram0
* SWAP must use with a SWAP partition in sdcard.
Code:
mkswap /dev/block/mmcblk1p2
swapon /dev/block/mmcblk1p2
* Because we have a large memory, the zRAM/SWAP is low activity.
* Some users said that zRAM/SWAP wont help the performance of games,they might drop more battery.
NTFS:
* Need a binary called "ntfs-3g" to read/write ntfs sdcard. Built-in NTFS feature only can read.
* Stock Android 2.3 cannot mount NTFS sdcard automatically.
Mali GPU:
* Allowed larger memory.
* Allowed larger OS memory for buffer. ( 6m -> 10m )
* L2 cache max reads tweakable
* Enabled some features in Makefile.
* Disable a big debugging checking
Audio Tweaks:
* Enabled directly rendering
* Enabled 32k_clk ( a feature of AB8500 )
* Volume Boost! ( v3.6-3.8rc,optional in v4.0 )
* Dynamic Range Enhanced! ( v3.6-3.8rc,optional in v4.0 )

1. Flash the kernel which has TWRP via Odin. You can flash diego-ch's TWRP kernel, or flash "GT-I9070-Kernel-CoCore.tar.md5" in attachments.
Here diego-ch's TWRP kernel: http://forum.xda-developers.com/showthread.php?t=1873119
( flash custom kernel will increase binary counter!! )
2. Run Odin, Put the md5 files in PDA, Pit files doesn't need.
3. Only check "Auto Reboot" and "F.Reset Time"
4. Click Start to flash, wait for phone reboot.
5. Boot into TWRP, Tap Install, Select i9070_kernel_CoCore_TWRP.zip, Flash it.
And, if you have TWRP kernel already, flash the zip via TWRP directly.
Method 2 (Experienced users only)
This method will not increased binary counter, but ROOT permission is needed.
1. Get kernel.bin.md5 from i9070_kernel_CoCore_TWRP.zip
2. Put kernel.bin.md5 in sdcard
3. Run your favourite terminal app, type these codes
Code:
$su
#dd if=/sdcard/kernel.bin.md5 of=/dev/block/mmcblk0p15
4. Reboot
If you typed a wrong patition number, perhaps it will brick your phone!!!
Think twice before you hit Enter.
( Updates )
01/03/2013 Update: CoCore v4.1
Hmm,This is BETA version.
Block: Added ZEN io scheduler (Bases on noop,deadline and sio)
CPUFreq: Added Skywalker governor (FreqTable tweaked)
Mali: Increased the default l2 max reads 28kb -> 48kb
Mali: Disabled a big debugging tracking
RCU: jRCU -> TreeRCU (For better CPU/RAM throughput!)
NWFPE: Enabled ex-nwfpe
Please remove the mali l2 init.d script tweaks,guys
CoCore-mini 1.4 is at #842 post.
12/23/2012 Update: CoCore v4.0
Mali: Driver updated, re-tweak the parameters
ASoC/ab8500: Driver updated
NET/conf: Enable HSTCP(high-speed tcp),Westwood+,Veno,Hybla,YeAh configs. Cubic(stock) conf is default.
Block: Set BFQ as default io scheduler
Block: Automatic readahead cache size limit (depend on the size of your sdcard)
Block: Re-tweak SIO/VR/Deadline for flash nand devices
MM: SLQB -> SLUB
SCHED: Remove fair_sleepers, revert the parameters back to stock
MISC: Remove a ton of juck!!!, Highest complie optimization level, boot faster(compare to old versions,8800ms~9100ms now)
PS.
The cifs.ko and smbfs.ko have been put out ramdisk.They will be installed to /system/lib/modules (for faster boot)
And i forgot the changes,see my source on my github.There is a changelog.
To change the net configs:
Create a new init.d script:
Change the 'highspeed' to other confs.
Use `sysctl -a | grep cubic` to know what conf you can change to.
`ping` is the simple way to test whether the conf you use fix you or not.
For me,i am using highspeed now. If unsure,keep default(Cubic)
Code:
#!/system/bin/sh
sysctl -w net.ipv4.tcp_congestion_control=highspeed;
I have set the mali l2 cache back to 28kb by default.
To set it to 48kb(max).Use an init.d script.
Code:
#!/system/bin/sh
echo 0x00000030 > /sys/module/mali/parameters/mali_l2_max_reads;
The game fps should be improved a bit,
The values you `echo` must be HEX
BUT,if it doesnt or feels lagged,remove this script.
For me,48kb works well.
The volume++ version is volume boosted. (Someone requires this)
The lagged sound will be increased,too!
12/09/2012 Update: CoCore v3.9Beta8
This is BETA VERSION!!
CpuFreq: Added AbyssPlug (Base on OnDemand+Hotplug)
Mali: Increased the priority of OSMEM (5 -> 1) (See the dmesg)
Mali: Unlocked mali_l2_max _reads in sysfs (You can tweak this parameter now) (Dont set over 48)
(If you find a good value,please share with us!)
Mali: Misc tweaks
Kernel/hz: Fix the defconfig issue (Thanks! @hafidzduddin)
Net/SCH: Reverted back to stock (To experiment the latency of enabling mobile data)
Makefile: More optimization flags
PS.
The Mali parameters are in /sys/module/mali/parameters/
Use scripts/terminal to set them.
12/07/2012 Update: CoCore v3.9Beta3
This is BETA VERSION!
J4FS: J4FS driver works! Bugfree now!
CpuIdle: Revert the ApDeepSleep to stock,and added ApSleep++ custom state
(ApSleep++ and ApDeepSleep only works with non-hotplug governors,e.g: ondemand)
(New sleep state is disabled by default.You can enable them by yourself,if you prefer longer battery.)
CpuFreq: Added Aggressive, AggressiveX, Gallimaufry and GallimaufryX (These are optimazed version of Conservation/OnDemand)
CpuFreq: Fix a hotplug bug of PegasusQ
FS/SYNC: Removed Dynamic Fsync Control,added Ezekeel FSync Control
ASoc/ux500: Raise the pcm buffer size to MAX
NET/Scheduler: Re-tweaked, to experiment the latency of mobile data
Unknown: Fix the touchscreen sudden lost response (According to my using these days,it has been happended again!)
PS.
The FSYNC is enabled by default.Disabling FSYNC can improve IO performance.
In AnTuTu IO Test: Enabled: 350-400 Disable: 540-560
But disabling FSYNC can cause losing data!! It is at your own risk!!
Check the TIPS part to get how to disable it.
12/02/2012 Update: CoCore v3.9Beta1
This is BETA version, at #344 post.
12/02/2012 Update: CoCore v3.8.6rc
ASoC/ab8500: Use another gain mode in order to fix the terrible audio issue.
Sched: Reduce the latency of CFS Scheduler
PS.
The dyn_fsync will casue screen lag when you turn off the screen and there is a heavy io load.
If there isnt any heavy io load,it goes normally.
If you hate this,see the Tips part (#2 post) to get HOW TO disable dyn_fsync.
12/01/2012 Update: CoCore v3.8rc
CpuFreq: Tweaked the freq table of PegasusQ
Blcok: Updated BFQv1 -> BFQr2-1,Fixed the latency of BFQ issue. (BFQv5 is incompatible with Linux 2.6.35)
Sched: Tuned the patamerters of CFS scheduler (Use ThunderBolt's)
Sched_features: Enable Fair_Sleepers,Disable HRTICK
Mali: L2 cache max reads -> 48kb,Fix the mem leak issue.
NET: Set WestWood+ as default CONFIG
fs/sync: Added Dynamic FSync Control
(Improve IO performance greatly.When the screen is on,fsync is off.When the screen is off,fsync is on.)
ASoc/ab8500: Fixed the FMRadio volume balance issue. (Thanks @shut_down)
MISC: Removed a TON of JUNK!!!,And added a workaround to flash kernel quickly.
PS.
The benchmark screenshot is in the #304 post.
How to disable DYN_FSYNC? Check the TIPS part. (#2 post)
What is the flash kernel workaround?
In TWRP,use the Terminal fucntion,SELECT the folderr which has a kernel named "kernel.bin.md5",Start the Terminal,
And just type "fkernel"(No quotes),it will flash the kernel.bin.md5 automatically.
And i found that V(R) is a good io scheduler too.
The BFS CPU Scheduler is incompatible with our kernel.I am about to introduce this in the JellyBean kernel.
11/25/2012 Update: CoCore v3.7
RamDisk/TWRP: Added a temporary workaround to mount emmc(internal memory)
Block: SIO io scheduler updated. (2012 version) (Thanks @hafidzduddin)
CpuFreq: Fixed the name issues of governors (SetCPU cannot tune the parameters of governors, now fixed)
CpuFreq: Added LagFree, BrazilianWax, InteractiveX, MinMax and SavagedZen governors
(New governors havent been tested fully!If unsure, PegasusQ is recommended.)
I have tweaked the freq tables of most governors.
Mali: L2 cache max reads: 48kb -> 44kb , FPS increases (1-8fps) in simple scenes.
(Reserved 4kb for buffering, perhaps it will fix the sudden lag in games)
Sched: Fix SAMSUNG source code errors
Sched: Added AutoGroup Scheduler v4
Net/Sched: Re-changed the scheduler of net
android/logger: Reduced the logger size
ASoc/ab8500: Headset Volume adjusted, Dynamic Range enhanced! (i recommend using PowerAMP/RockBox)
PM(PowerManagement): Added a new feature, Operating Performance Point (OPP) Layer library
MISC: Disabled something useless(for faster boot),
Added GenLock API, MM&DMA hacked,
Added a new feature DM_CACHE,
more GCC optimizations in MakeFile
PS.
Dont use high volume to listen to music over 1 hour, it it not good for your ears.
Just reduce some volume.And i havent gained the speaker volume, dont worry.
The TWRP has some grapics issues when entering the emmc folder(it happends soemtimes, not always),
if it happended just tap back button and enter again.
(Some guys required this becaues them havent an external sdcard! )
And about the SetCPU issues. If you cannot tweak the parameters of some governors,
go to /sys/devices/system/cpu/cpufreq/(governor_name)/, you can tweak them here.
Make a script to tweak them quickly.
I think there is no point in updating to 2.6.35.14, because it updates a lot of useless drivers.
11/18/2012 Update: CoCore v3.6
Block: Added anticipatory io scheduler
CpuFreq: Added HotPlug and SmartAss governors
CpuFreq: Tweaked SmartAss and SmartAssV2 freqtable in order to match our device

ab8500/asoc: Headset volume gain boosted! (Sounds perfectly.My ears will be satisfied with i9070+Edifier H850. )
11/11/2012 Update: CoCore v3.5
Kernel: Revert LZO compression ( LZO is the fastest, but it makes kernel largest )
Kernel: Removed some bad tweaks
Kernel: Compile with Linaro GCC 4.4.5 ( The final version of Linaro GCC 4.4 series )
Ramdisk: For power saving, cifs.ko and smbfs.ko will not be loaded by default
Block: SIO, V(R) and Deadline io scheduler tweaked ( Better IO throughput )
FS: EXT2, EXT3 and EXT4 speed up
JHash: Updated to JHash v3
Sched: Enabled HRTICK
RCU: Added and use JRCU

MM: Added vzalloc() and vzalloc_node() helpers
MM: Added and use SLQB memory allocator
MM: Added fudgeswap
SYNC: Added synchronization framework
BCM4330(WLAN): Enabled PM_FAST mode in standby
CGroup: Enabled FREEZER feature
PS. And many misc tweaks.
And i added some modules in /lib.
I tweaked mali parameters again (MEM -> 48MB OSMEM -> 8MB).
Because i find that when the memory is too big, it feels lag.
According to my test, in simple scence, fps increases (1-2fps); in complex scence, fps reduces (1-2fps).
But UI is faster in low frequencies! ( i often use signle core at 800Mhz )
10/28/2012 Update: CoCore v3.1
Mali: Fixed the fps issue.
RCU: Use Tiny-PREEMPT RCU (To reduce memory footprint, and feel more smooth)

The source code is available on my github now.
If there are any issues, please report.
And if you like my work, Press THANKS Button Please. It encourages me.

( Tips )
1. For performance, please remove libGLES_android.so in /system/lib/egl to disable weak CPU rendering.
2. Flash your kernel quickly via Ternimal.
Creat a new file (named `ddkernel`) with RootExplorer.
Write these codes:
Code:
#!/system/bin/sh
source=`busybox realpath kernel.bin.md5`;
echo "DD: Flashing $source";
busybox dd if=kernel.bin.md5 of=/dev/block/mmcblk0p15;
Save , and set right permissions (0777), put it in /system/xbin
Now, you can `cd` to the folder where stores `kernel.bin.md5`, and use `ddkernel` command to flash kernel.
3. Mount your NTFS sdcard
Firstly, you need a binary called "ntfs-3g". Put this binary in /system/xbin
Open your terminal app.
Code:
mkdir sdcard-ntfs
ntfs-3g /dev/block/mmcblk1p1 /sdcard-ntfs
4. My sysctl.conf
Code:
vm.dirty_expire_centisecs=3000
vm.dirty_writeback_centisecs=500
vm.dirty_background_ratio=40
vm.dirty_ratio=80
vm.vfs_cache_pressure=1
vm.highmem_is_dirtyable=1
To use this file,you must have installed busybox,and put this file in /system/etc
Go to /system/etc/init.d/,create a new file(Any name you like),write this(Remember to set right permissions(rwxrwxrwx) of new file):
Code:
#!/system/bin/sh
busybox sysctl -p;
Now your sysctl.conf will be loaded automatically in every boot.
5. How to disable Dynamic FSync Control? (CoCore v3.8-v3.8.6 ONLY)
In your /system/etc/init.d/,create a new file
Code:
#!/system/bin/sh
echo 0 > /sys/kernel/dyn_fsync/Dyn_fsync_active;
Now,this function will be disabled in every boot.
6. How to Control the FSYNC? (CoCore v3.9+)
In your /system/etc/init.d/,create a new file(any name you like)
Code:
#!/system/bin/sh
# Disable FSYNC
echo 0 > /sys/class/misc/fsynccontrol/fsync_enabled;
# Enable FSYNC
#echo 1 > /sys/class/misc/fsynccontrol/fsync_enabled;
Or you can control the FSYNC via terminal realtime.

Good work!
Just I have a request
Can you try this on JetMOD and tell me if Power menu options of Reboot, and Reboot recovery works?
I am planning to ship this kernel in next update of JetMOD

tnx allot dude, i`m sad that i am at the office and can`t test your kernel :|

I have made CWM. Should i include it in the boot image and flash ?
I dont see any zip which includes the .img format..

after flashing it by TWRP, it stuck on boot logo :S
i was using jetmob rom before, and need to restore the backup.. i'v tries twice, and same boot logo stuck..

Great, You have made CWM for i9070?
i9070 kernel format is zImage, not boot.img.
You can fork the kernel repo of diego, replace the recovery files, and complie kernel.
Put it in dev thread.
We will test it.

installing these kernel?

hi cocafe.
your custom bootanimation work?
in my kernel custom bootanimation loops never stop.
i use diego-ch ramdisk
im a user of galaxy ace 2

What is that CPU/b2r2 rendering?
Is that audio tweak included without flashing " optional scripts? If I do not want to enable "Deepest Sleep" and "Mount" from optional scripts zip, is it enough to delete them from the zip?

Yes, several weeks ago, i fixed that loop bug.
You can check the ramdisk of my kernel. There is a small workaround in post_boot.sh.
Here the method:
in init.ux500.post_boot.sh, write these code
# fix custom bootanimation loop
sleep 4;
bootani=`ps | grep bootanimation | cut -b 10-16`;
kill $bootani;

[KERNEL] Galaxy Tab S 8.4 SM-T700 (klimtwifi) Permissive kernel - T700XXU1ANF7

[size=+2]Samsung Galaxy Tab S 8.4 (klimtwifi) - Stock kernel SELinux permissive mode[/size]
[size=+1]Introduction[/size]
This kernel is built from stock Samsung source T700XXU1ANF7.This kernel will work on a stock, rooted Tab S 8.4. In addition, I run EMSPilot's NF9 ROM, so this kernel also works perfectly fine on his ROM. Thanks EMSPilot for the great ROM.
[size=+1]Features[/size]
The kernel is completely stock except for the activation of kernel configuation options allowing SELinux to be disabled and the mode to be changed from enforcing to permissive at runtime. It also supports the boot parameter androidboot.selinux=permissive and enables adb insecure in the default.prop in the ramdisk.
[size=+1]Installation instructions[/size]
To install this, use Odin 3.09 to flash the SM-T700-permissive.tar.md5 image using the AP button. DO NOT USE THIS KERNEL ON ANY DEVICE OTHER THAN A SM-T700 KLIMTWIFI. You are responsible for your own device and I make no warranty for this kernel. Flash at your own risk.

Kernel Special Features: SELinux runtime mode change enabled
Version Information
Status: Beta
Beta Release Date: 2014-10-22
Created 2014-10-22
Last Updated 2014-11-08

Thank u for this! I'm Gunna give it a try here tonight!

Thanks d12345 and to emspilot!

Thanks for sharing your method. Much appreciated.
I currently use a dirty RAMDISK method with my Tab S kernels and a hardcode source method with my Note Edge kernel. I look forward to trying this way next kernel i compile for test.
The dirty way actually removes the SELinux from about device in settings, where the hard-coded way just changes it to "permissive" but is permanent.
Does your way change the devices settings and visible, or is it removed all together (check status with getprop) ?

Thanks man this kernal gave me access to use my wireless xbox controller awesome man!

Hi yes I posted in this thread http://forum.xda-developers.com/galaxy-tab-s/help/gamepad-game-controller-t2820410

Worked great!

Hi, this kernel can be used with a 6.0.1 marshmallow rom?

"seandroid not enforced" and bootloop in recovery
sm-t700 wifi, non-system rooted (rooted but not a system root)
how the title, I installed the selinux permissive with odin (ap)
restarted to enter twrp and saw "seandroid not enforced" red, wrote up/left display,
wiped dalvik in twrp and restart to system, and always twrp,
tried to restart to system again, and twrp a new time..
I am recovering now (i saved boot too, in backup), hope to solve..
-------------------------
refresh, solved with full backup.
knox was completely off.. probably this permissive linux is not good for
marshmallow 6.01 or for this tablet particular firmware..

Evervolv 7.1.2 SKZ Kernel with Swap partition enable and optimized

No need to follow this, Flash Files are available here to do automatically !
https://forum.xda-developers.com/hp-touchpad/general/hp-touchpad-optimize-android-swap-t3901773?nocache=1
Do not judge by how the device will work by looking at the code, which is completely different from what have been suggested all this years.
That is the reason I am providing the boot image. So that you can test it on your tablet and see it for yourself.
None of this will create any damage, is the opposite your tablet will have less work to do and work faster.
Before trying this out you must have already created a swap partition here are the steps:

https://forum.xda-developers.com/hp-touchpad/general/how-to-create-swap-partition-size-t3892060
If installing on a running system with a swap partition, or you back up the system and then restore it after creating the partition.
The Dalvik/Art Cache
Cache
Must be wipe using TWRP ( For all settings to work properly )
What would the changes do?
Make the HP Touchpad work as originally intended, a tablet not a smartphone.
You will be able to play HD 720 videos, using google youtube app and any browser.
Use Google Maps, Google Earth and many others apps that is impossible to use now.
CPU settings (The normal that all tablets will work) It can be increase to 1890000.
MAX 1728000 Minimum 192000 interactive
Readahead buffers (as per LVM)
4096
Scheduler bfq
The following Skz Kernel modules permanently removed. Even if the module is disable its settings will be active, that is the reason of the removal.
Code:
# CONFIG_HOTPLUG is not set
# CONFIG_INTELLI_PLUG is not set
# CONFIG_ASMP is not set
# CONFIG_HOTPLUG_CPU is not set
# CONFIG_KSM is not set
# CONFIG_UKSM is not set
# CONFIG_ANDROID_LOW_MEMORY_KILLER is not set
# CONFIG_ANDROID_LOW_MEMORY_KILLER_AUTODETECT_OOM_ADJ_VALUES is not set
The following Ramdisk files have been modified to apply the optimum settings.

Download the file and copy it as is in your boot directory using TWRP. That is if you have extra space for 5.9MB, you should if only using Android.
Before booting you should have already disable any app that you have installed to optimized the settings, otherwise settings will be overwriten and will not take effect.
After booting for firs time, depending on how many apps you have, it could take very long time to be ready for use.
Give it some time, let it rest and finish rebuilding.
Many thanks to everyone that work on the Evervolv Team that provided the TP users with this great ROM and also to Shumash for creating the fastest Kernel for all Android ROMS.

Do not judge by how the device will work by looking at the code, which is completely different from what have been suggested all this years.
That is the reason I am providing the boot image. So that you can test it on your tablet and see it for yourself.

Going to have to give this a try.
Thanks for taking the time to put it together.

@HP_TOUCHPAD. Cheers for this man. I've flashed the rom yesterday and followed the guide after you posted the final version.
Evervolv 7.x feels really snappy

Yes all the ROMs works the same as it have the same settings. Pick and the one you like the most all work with the same speed.
Thanks for trying it out and reporting, enjoy your brand new Tablet. !

Not all the roms. Picked DU 12.5, which was Oreo based, I believe, and it was sluggish. That's why I chose the other ROM.
Anyhow, I'll test the Other roms as they come. Feel free to hit me up/mention me if you need testing.
Great work, man, keep it up!

I want to make sure we are on the same page, you installed 7.1.2 using this guide and flash the proper speed for your tablet:https://forum.xda-developers.com/hp-touchpad/general/hp-touchpad-optimize-android-swap-t3901773
You also installed 8.1 from that guide but found it slow?
Did you tried 9?

Is there any advantage to using to this SKZ kernel over the Max 1836 kernel? Or is your Max kernel included in the "All files for this rom.zip" based off of this kernel? Also, does the Max kernel include the GPU overclock? I noticed the Touchpad is a bit lacking in the GPU department.

This is an obsolete guide, it is posted on the first page:
No need to follow this, Flash Files are available here to do automatically !
HpTp_Max and HpTp_MaXtreme (optimized settings ) includes everything.
The HP Touchpad lack of everything, is an 11 year old device, now in 2022.
But still functional in many ways.

Ok, thanks. And to confirm, HpTp_Max does include the GPU overclock too right?

For all ARM based devices, the GPU is built into the CPU ( combo ) same as desktop or laptops that do not offer a dedicated GPU.
For the HP Touchpad:
ChipsetQualcomm APQ8060 Snapdragon S3CPUDual-core 1.2 GHz ScorpionGPUAdreno 220
The 1GB RAM is shared by the GPU, some of that RAM is used by the GPU for the driver resources.
Then Android run a Virtual Machine for the java apps and the graphics settings are specified in the build.prop.
If you are familiar with virtual machines on the PC, there are settings to allocate GPU RAM for the graphics ( display settings ). It does not matter how fast or new the GPU card is, but how much RAM is assigned to the virtual machine to be able to handle the proper display resolution.
The same applies to Android, if the settings to run the virtual machine in the build.prop are not properly configured then nothing will run regardless of how overclock the GPU is. The lack of graphics performance on the tablet is due to 1GB or RAM and that is why the importance of the swap partition to gain some RAM.
There is no magic code to improve or make the display better because is all about " RAM " and there is only 1GB for everything.
If you would like to see all the settings from any Kernel that is running on the Tablet, then you can install Kernel Adiutor, just to check the settings.

Yes, I know it's integrated into the SoC. It does seem to have a separate clock speed though.
The original thread for the SKZ kernel mentions a GPU overclock as well: https://forum.xda-developers.com/t/...vervolv-7-1-x-1890khz-cpu-320mhz-gpu.3513534/

Install Kernel Adiutor and you will see all the settings. It must be uninstall or better re-flash the ROM to avoid any issues.
As already mentioned, the issue with the GPU is the limited about of RAM, not the clock speed.

I have to say thanks to HP_TOUCHPAD for his consistent replies and guidance for overclocking and getting this tablet to work again.

You are very welcome ! A lot of developers spent a lot of time on this Tablet, they deserve all the credits.
