I think before judging a kernel, we have to make 3 or 4 complete battery cycle.

Hi by that do you mean:
1- Charge phone fully 100%
2- Go to recovery and wipe battery stats
3- Unplug charger
4- Use phone normally till it drains to 0% and switches off
5- Charge fully to 100% while phone is switched off
6- Unplug charger
7- Repeat steps 4-6 3 or 4 times

Correct me if i'm wrong.

Yes you could use that method but draining your battery until its shut off is not good or drain to 0%. Since our batteries are li-on.

Better to charge atleast when it reaches 5-10, but 20 is recommended :eek: ill stick to 5-10 percent :)

I 've done it a lot of times without issue for the battery. I think that everything is designed to work till shut off because what we think is 0% is not a real 0% but the minimum level the chip turns the phone off to avoid damages.;)

Great thanks for the replies also wanna know is it better to wipe battery stats manually through recovery or using a calibration app?

I'm not sure It really works but It takes just 2 seconds so... why not? :D
I use the app. Just charge the phone (turned off) for at least 4 hours (5 is better). Then turn it on without unplugging the charger. Run the app (it needs the root access). Press the calibration button and unplug the charger. :cool:

Just a discovery I've made a few weeks ago, we can actually overclock and undervolt with Speedmod kernel, thanks to Tegrak.
This app is not free to have all features but I've tried and it works without issues (with JB LSD rom). Pretty cool to have both speedmod and oc - uv. :)

I have installed speedmod kernel a few minutes ago. I have run antutu benchmark + omega v20 rom without any oc, with these results:

hardcore will update his kernel?

Updated version is out.

K5-2:
- Updated to GT-I9100_JB_Opensource source code
- Implemented kernel hack to support CRT-off animation

No new CWM yet.

Just to clarify, you can back up and restore your *data* with this CWM5. It just does not backup and restore the /preload partition, which is normally only changed if you flash a new ROM.

I have installed "ExynosAbuse-v1.40.apk" and it says: "CURRENT STATUS - Exploit: exploitable".

Don't use Exynos Abuse app to test the exploit.
Use the ExynosExploitDemo apk from chainfire instead.
This will do the check correctly.
Should show a toast message after rebooting, that the Exploit failed.
Please report back here, as I have no time to test it myself in the next few hours.

    Hi guys,

    This is the SpeedMod kernel for Android Jelly Bean for the Samsung Galaxy S2 GT-I9100.

    This kernel only works with Samsung JB based ROMs.

    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

    >>> CLICK HERE for more info and the DOWNLOAD links.

    >>> CLICK HERE for the Frequently Asked Questions list.

    Current features:

    Root and CWM:
    - Automatically installs root (su) but can be disabled
    - CWM recovery 5.x

    Screen and misc tweaks:
    - init.d, TUN, CIFS, IPV6 Privacy support
    - MMC_CAP_ERASE disabled to fix the hard-brick bug (this kernel is "safe")

    Performance:
    - CPU governor tweaks: increase responsiveness
    - IO tweaks
    - Read ahead tweaks
    - Compiled with optimizations using Codesourcery GCC toolchain
    - Multi-core aware scheduler SCHED_MC

    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

    >>> CLICK HERE for the CHANGELOG.

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

    >>> CLICK HERE for more info and the DOWNLOAD links.

    K5-8:
    - Rebuilt using GCC 4.6 toolchain from Android NDK r8

    I think the kernel behaves a bit better built using GCC 4.6, compared to GCC 4.7 with LTO.
    41
    K5-5:
    - Rebuilt using GCC 4.7 toolchain from Android NDK r8e
    - Enabled GCC 4.7 LTO (Link Time Optimization)
    34
    K5-6:
    - Security patch: fix stack memory content leak via UNAME26 from S3 Update9 source code
    34
    K5-7:
    - Disabled debugging: ANDROID RAM CONSOLE
