Since I use Speedmod kernel, my computer don't recognized the phone anymore.
So I can't transfer any file to the SD card right now.

Does anyone have the same behavior?

No problem here, i think u have a driver problem

Thx for hearing such a good Information ;)

Hardcore has no obligation to answer on all types of 'ETA' questions.

Us layman should show appreciation by having faith and waiting patiently. Not demanding.

Especially if what we do is just come here and download.

In rude terms, we are 'leechers'

So yeah, when it's ready tomorrow, it'll be there. If not then later should come.

Can't wait? There are plenty of other kernels.

Installed the kernel last night but I cannot find the "Voodoo Screen Tuning App" in the market. Can someone pls post a link for it and share your settings?

Thank you


I think you'll find that Hardcores' MDNIE tweaks breaks the 'original' Voodoo screen tuning app . . . I seem to remember reading it in the apps notes (but that app seems to have been discontinued on the market)



Hi guys,

.....
Screen and misc tweaks:
- MDNIE screen sharpness tuning (improves text readability)
- MDNIE color tuning (reduces over-saturation of color)
- Lower brightness at low-light levels
- init.d, TUN, CIFS, IPV6 Privacy support
.......

I have a question here, when i limit my CPU speed to 800 or 1000 MHz using CPU Master or Set CPU or System Tuner it seems the system still jumps to 1200.

Any idea why the limit is not effective?

I highly doubt i will flash another kernel unless it's actually posisble that Hardcore can make it even more battery friendly which would be a big IF, this kernel is simply amazing, undoubtedly the best Speedmod release to date (K2-21)

check screenshots below, Data and WiFi off on standby but still pretty awesome.

Donation coming your way Hardcore when i get paid.

I agree with you, but 6-7 hours isn't a real benchmark.

Currently on my first full cycle:
1 day and 12,5 hours
Of which 2,5 hours of display time, 0,5 hour phone calls, Wifi on all the time and a lot of whatsapp, facebook and internet use
Still have 44% left

Will post final results with screenshots when battery is under 5%

Better use voltage control, much more reliable than SetCPU or the other apps.

    Hi guys,

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

    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

    WARNING: This kernel does NOT work on the GT-I9100G. GT-I9100 ROMs and kernels are not compatible with GT-I9100G.

    >>> 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)
    - CWM recovery

    Screen and misc tweaks:

    - USB charging speed increased by 10%: current limit set to 500mA

    K2-3:
    - Revert faster USB charging speed, it was causing instability for some USB ports
    - Disable Mali-400 GPU state tracking
    - Minor bugfix to Exynos cpu suspend hotplug

    K2-5:

    [HOW TO ENABLE LOGCAT]

    If you are a developer or want to re-enable logcat for whatever reason, do this:

    adb shell
    su
    mount -o remount,rw /system
    echo ANDROIDLOGGER >> /system/etc/tweaks.conf
    mount -o remount,ro /system

    Reboot and you should have it enabled.
