This kernel is for Samsung Android Jelly Bean ROMs only.

SpeedMod's core features are:

- Super stable: No undervolting, overclocking or potentially unstable modifications

- Fast and smooth: Compiler and code optimizations

- Excellent battery life: Remove unecessary logging and debugging

Current features:

Root:

- Automatically installs root (SuperUser and su) but can be disabled

Screen and misc tweaks:

- Auto-brightness increased slightly (in low-to-mid light)

- MDNIE screen sharpness and color tuning (improves text readability)

- init.d, TUN, CIFS, IPV6 Privacy support

- Fixed freeze on FC problem with Samsung ICS & JB ROMs

Performance:

- CPU governor tweaks: increase responsiveness

- IO tweaks

- Read ahead tweaks

- Compiled with optimizations using CodeSourcery GCC toolchain

- Optimized GPU DVFS

- ARM CPU topology support

- SCHED_MC multi-core aware scheduler

Turned off unnecessary logging for better smoothness and efficiency:

- Disabled Android Debug Logger / logcat

- Disabled Samsung debug

- Disabled various kernel debugging, statistics and tracing options

Instructions on how to enable logcat and disable auto-root are in the 3rd post (below).

Great!!!!! Thanks for the hard work Hardcore. Just one issue, when downloading the file says "speedmod-kernel-s3-ics-k1-8-Odin.tar" shouldn't be K2-1??
[Galaxy S III Original Android Development] cbeckstein:
it's just the wrong download link from the latest ICS kernel version (cut and paste error?)

the following educated guess did the job for me: http://vln01.helochat.com/tourist/speedmod-kernel-s3-jb-k2-1-Odin.tar
[Galaxy S III Original Android Development] hardcore:
Oh yeah. Darn the download link was pointing to the ICS version. DON"T FLASH THE ICS VERSION on JB. I'll update the link.

If you have, don't panic. Just flash the JB version when I update the link.
[Galaxy S III Original Android Development] dani_mola:
bad link

Hello hardcore, simply to warm you about the blog link, it points to speedmod-kernel-s3-ics-k1-8-Odin.tar instead of speedmod-kernel-s3-jb-k2-1-Odin.tar

Thanks for your effort!!

OP says this kernel has init.d support, but I can't get ExtSd2InternalSd mod to work. It works with all custom kernels we can found down here, but not with my so loved speedmod. That's just a file put in init.d folder, so I guess there's something wrong in init.d support...

Hi to all,

Sorry for mine question, that could appear strange.

Someone of you have tried the Yank555 kernel?

If the answer is yes, which kernel is better, this one or Yank555?

I'm referring to phone responsiveness, battery life etc.

Hope my question didn't make anyone become angry, just looking for information
[Galaxy S III Original Android Development] jeremy_inc:
I have a problem - when I try and record video using the main camera on the kernel, it doesn't work. It only happens with this kernel, when I flashed the stock one its OK.

Further details:

Recording video from front-facing camera works fine

Taking pictures on both cameras is fine.

Trying to record video using another app also does not work.

I am using NEATrom XXELLC

Any ideas?
[Galaxy S III Original Android Development] RS050377:
This is a known problem with custom kernels, but there is a video recording fix with old libs.

Init scripts are run from particular folders. Can't remember offhand but check /data/user.log for clues.
[Galaxy S III Original Android Development] Bengaal:
Thanks Hardcore! Everything feels smooth on first bootup.

small question though, I came from siyah and had uv and stuff. Do you think that will be a problem. Did I have to reset those siyah settings?
[Galaxy S III Original Android Development] gamin92:
Re: [KERNEL] SpeedMod S3 Jelly Bean [ K2-5 SDS_Fix ExFAT ROOT BRIGHTNESS+]

Do you mean Hardcore gives an other path than /system/etc/init.d to init.d folder? Will have to flash it back to check it...
[Galaxy S III Original Android Development] AndroidGX:
STweaks app will not work on this kernel (incompatible), so you can delete safely the .siyah folder located in your data partition.

Re: [KERNEL] SpeedMod S3 Jelly Bean [ K2-5 SDS_Fix ExFAT ROOT BRIGHTNESS+]

There is a app that is called pimp my rom. That can enable or disable almost everything. Try that..

Nice seeing a new kernel hardcore!

Only thing that is a bummer right now is the updated bootloader with the red mark on the boot everytime.

Yes i know i can downgrade to an older bootloader. But i do not want to do that.

Is there anything you can do about this ?

Re: [KERNEL] SpeedMod S3 Jelly Bean [ K2-5 SDS_Fix ExFAT ROOT BRIGHTNESS+]

Buy Mobile Odin and flash tar files that way, or flash using kTool buy unzipping zImage out of tar file.

Your bootloader should not detect these methods, I am on older bootloader, so I cannot 100 percent certain
[Galaxy S III Original Android Development] ZaneZam:
unfortunately not! there are signature checks in all directions on new bootloaders! they check kernel image and recovery image and if either of them are not stock the red mark appears. the only thing we can do is downgrade to older bootloaders which doesn't contain these checks and avoid to flash new ones. some time ago i had a bootloader (i think it was on a 4.1.1 rom which i got from OTA update) which apparently had not yet full implemented all checks and i figured out that it was possible to avoid that mark at least for kernel images by chanigng the build process of the kernel (other way of including initramfs in the image) but that doesn't work any more on newest bootloaders and leads to stuck on boot! So the kernel dev can't do anything against that damn mark! Samy obviously wants to stigmatise people who changed their systems for what? Maybe for warranty refusal or whatever... ;)

@Brotuck

why do you not want to downgrade to older bootloaders? i got rid of that mark and even of flash counts by flashing an older bootloader! No counts (at least with mobile odin, not testet with odin), no mark, no problems! :victory:

[Galaxy S III Original Android Development] hardcore:
SDS fix is actually part of the Update7 source code. Update7 also supposedly includes the security fix. So if you apply the patch on Updated7 you will get it.
[Galaxy S III Original Android Development] Brotuck:
Flashing bootloaders is a big(ger) risk, so if i can avoid it i will.

The second reason is because the exploit still being active on the older bootloader. But then again isn't the SDS fix supposed to fix that ?
[Galaxy S III Original Android Development] BrandoHD:
Re: [KERNEL] SpeedMod S3 Jelly Bean [ K2-5 SDS_Fix ExFAT ROOT BRIGHTNESS+]

Odia has posted a way to get back your old bootloader without too much risk

Bootloader has nothing to do with any fixes as far as anyone can tell
[Galaxy S III Original Android Development] Brotuck:
Yep found it and flashed older bootloader files.

Finally back on Speedmod without that nasty red line :)

First impression is :good: on XXELLC, slightly more battery per hour then the stock kernel.

But i guess i have to wait a few days for more accurate measurements.

Re: [KERNEL] SpeedMod S3 Jelly Bean [ K2-5 SDS_Fix ExFAT ROOT BRIGHTNESS+]

Hi hardcore. Is there a way to check why stock kernels now are better in battery usage? Getting now 0.4% values and with the latest speedmod i get around 1.0% values.

Use the traditional init.d folder renaming the scripts in S<number><name>

or put those in system/etc/init.d

or in data/init.d

is obvious from the file that you explained hardcore

Then stop with this legend in the SpeedMod init.d does not work

I would have stop "with this legend" before if that was explain somehow in OP ;)

I have made a similar experience regarding battery. Also, I think Stock Kernel is running smoother. How can that be?
[Galaxy S III Original Android Development] Brotuck:
Yes the latest EMA2 version is even better in the framerate.Batterylife is also better there.

BUT

I do miss the other optimizations from the speedmod kernel. ;)
[Galaxy S III Original Android Development] Willy89:

Hi. Could you please make your awesome kernel (the best that i've tried so far) compatibile with crt off effects?
[Galaxy S III Original Android Development] DroidSensei:
I have the same problem. I tried also to made a call with another phone. The result is that the galaxy s3 doesn't vibrate and the screen is off. So if I receive a call I'll miss the call. :(

However the battery consumption is decreased thanks to this kernel. :laugh:

I hope the problem will be solved with an update :)

Bye
[Galaxy S III Original Android Development] supreethms:
Try a reset.

This doesn't generally happen with kernels..

o_O

I don't know.. Because i have been installing many kernels from Galaxy mini to S III..

And, why don't you give the developer a logcat so that he can help you better..

[Galaxy S III Original Android Development] DroidSensei:
Re: [KERNEL] SpeedMod S3 Jelly Bean [ K2-5 SDS_Fix ExFAT ROOT BRIGHTNESS+]

Very strange but now I have not this problem :)

I have a doubt. The reason could be the recovery, now updated (the philz touch).

If I will have the same problem I will reset my phone.

[Galaxy S III Original Android Development] Brotuck:
CRT support is not build into the kernel. That is something build into the framework. Use the framework of jkay for that for example.

In jkay thread i've been told that this la related to kernel...
[Galaxy S III Original Android Development] andip71:
Yes, fully can confirm that (as I am a kernel dev as well).

You need

- a kernel that supports it if the kernel bases on Samsung S3 sources update7 (before it was not required)

- the framework mod of course

Andi
[Galaxy S III Original Android Development] Willy89:
So this kernel could be modified to include it?

He could just use the commit from codeworx which he can also find in my repo (https://github.com/andip71/boeffla-kernel-jb-u7-s3/commit/2e3f3812238299c3cc10abc1e5b31a0c9dbfde93).

K2-6:

- Updated initramfs scripts from XXEMA2 Android 4.1.2 kernel

- REMOVED Samsung ExFAT module support to enable optimizations

- Rebuilt using Codesourcery 2012.03 GCC 4.6.3 toolchain

- Implemented kernel hack to support CRT-off animation

IMPORTANT: I've decided to remove ExFAT support from K2-6 so that I can enable more optimizations (disable more debugging and use a newer compiler). I believe the battery life and smoothness should be improved by not having to compromise optimizations to load the closed-source Samsung ExFAT modules.

If you use an ExFAT formatted SD card, you can just reformat it as FAT32 and it will work.
[Galaxy S III Original Android Development] Willy89:
Trying it right now!!!!

Will report soon!!!

EDIT: CRT-Off works fine even if wifi isn't online!!!

[Galaxy S III Original Android Development] Brotuck:
Hi Hardcore,

I have run K2-6 for a day now, and i am totally amazed !

It really is the best powersaving Kernel there is.

Average usage is 0.4 - 0.6 % per hour now !

And that is on a totally stock ROM (XXEMR2) with some stuff removed (like dropbox, chaton ...)

Wifi on all the day (2,4 ghz band)

Facebook, Exchange, Whatsapp, Gmail are all running with push notifications.

Totally happy now :laugh:

Re: [KERNEL] SpeedMod S3 Jelly Bean [ K2-6 SDS_Fix ROOT BRIGHTNESS+ ]

I'm struggling to understand how you got that battery life with all that stuff running, I'm running this kernel with sotmax and I don't get anywhere near that battery life.
[Galaxy S III Original Android Development] Brotuck:
Re: [KERNEL] SpeedMod S3 Jelly Bean [ K2-6 SDS_Fix ROOT BRIGHTNESS+ ]

Location awareness and svoice are also removed. I did not bother to wipe at all. Have not done so in the latest 5 roms.

I do notice that it sometimes is nessecary to let the battery drain to 5% once and let it charge fully. But this could easily be placebo. I do exchange the battery for another when i forgot to charge the phone... :D

Yeah maybe it is a good idea to share the removed stuff for the ultimate batterysaving experience. Thinking about that.
