Hi I'm currently on chainfire's DXKF1.

Can I flash speedmod's K1-T8 directly? or do I need to flash to KG3 first before flashing with speedmod?

Please help, thanks

I woke up this morning and had exactly the same question.

I would like to have the combo KG3 + Speedmod K1-T8 as it seems to be fast and gives a long battery life and solved WIFI issues

Could someone add a small screenshot of the correct ODIN setting (please don't shout at me

, I am but a noob)

Also I noticed that there is a zImage in the rar file? What to do with this?

Hope this helps:

1. Things to be ticked / marked (whatever you call it): Auto Reboot, F. Reset Time (ONLY THIS TWO)
2. Click PDA (of course, Odin up first, followed by USB to phone, You will see ID:COM turns yellow, the click PDA). Choose the same file you download from page one. DO NOT UNZIP.
3. Press Start. Wait for reboot and you will be just fine

and if I want to be on KG3 with this kernel I first have to do the same with KG3 ?
I am currently on KF2

Uhm for me wi-fi is working on VR 2.1

and speedmod kernel ofc

Oh and "Android OS bug" seems gone

At a better look seems also that the "banding yellow on the left side of the screen" are gone like the KGx Kernels, and the "darker bottom side" of my unit is less noticeable.

Have been fan of your work on the wholy SGS 1
Was hoping you would come to the SGS 2 and there you are
I donated to your work and am happy I did,
Running this T8, no issue so far, and the device "feels" smoother for sure
Will be waiting future releases !
Thanks !

Seems like almost everyone on here is reporting better battery life when using speedmod... I'm on KG2 rite now and very tempted to make the change too.

Hmm close to 1h of display auto brig 14% batt lost no Os bug and by far lot snappier and fast

Btw I can't see tapatalk in the battery usage stats... So maybe the bug is still here but not visible (like some apps)

Can you post all your specs in regards of your setup ?
I think you are the only one that can get wifi running on VR21 and this kernel. I have yet to see another confirmation that it works.. It does defenetly not work for me.

I'm using vr 2.1 nothing strange btw I'm using a static ip and maybe that make the difference

@hc:

nevermind, I just tried this 2.6.35.11 kernel and found out it has the same dual core problem. Obviously samsung fixed this somehow in current stock kernels (KG2/KG3).

What do you mean for dual core problem?

@hardcore

Nice to see you here
there is a dual core issue in the kernel source you are using. some apps (games) crash or freeze with this kernel version. the issue is fixes with samsung kernel KG2. .

I think the issue is not fixed in KG2 kernel. I have some crashes and freezes with it too..

beppez82 said:

Issue: http://code.google.com/p/android/issues/detail?id=17623
Workaround: Turn Off sound in such games/apss -> then it runs without any freezes

russell.nash · Jul 26, 2011

The problem was very frequent on KE4/7 for me. On KFx it got better but was not gone, since KGx I cannot reproduce it any longer. I have no idea if it is really a sound issue. It feels like a code deadlock, since CPU is getting very hot sometimes it happens...

EDIT: I cannot confirm that this is a sound issue. Even with sound off the problem can be produced.

That may be the difference

The problem is that the connection is hanging while getting ip from the DHCP server ...

With sound off in options in game (not with volume down button) problem can be reproduced??

The only way I found to prevent the problem is using a stock kernel > KG1. If you flash CF-Root KG3 to name an example my problem is gone. CF is a pure stock kernel with several script addons.

Locster126 · Jul 26, 2011

Been using this kernel for two days. Battery seems similar to stock kernel but i don't like the fact that logcat and dmesg is disabled and lastly that things like android os are hidden in battery stats. I do like to know what's going on in the background on my phone.....

Then flash cf root kg2 with odin on your rom...afterwards you have cwm and can flash this kernel as i described

Thanks for the tip. I tried this method but now my recovery is 3E and I seem to have lost 2E.

noncents · Jul 26, 2011

Aww man.. I tried flashing to speedmod k1-t8 but was unsuccessful.

I had flashed kernel under cwm from KF1 to KG3. This part was successful.

Thereafter, opened up Odin, click speedmod under PDA with phone connected by it showed unsuccessful.. anyone know what I missed?

K1-T9:
- Updated initramfs from 2.3.4 (XXKG3)
- Disabled scheduler stats
- Disabled Samsung kernel debug settings

Quadrant scores around 4000 now!
