There are 3 optimization that is done by this update. I fine that the change for writeback journal mount option is worthwhile. I wonder why writeback isn't the default mount option for /data and /cache partitions. I am sure the dev have discussed about it though. Anyways, unfortunately the way this patch try to achieve this does not really work. I understand why the dev did it this way though (using remount), probably because he wanted to support many different devices easily. You will have to follow this thread to do it the correct way. Of course do this only if you know what you are doing.

I did it in recovery using adb with the following commands.

adb shell tune2fs -o journal_data_writeback /dev/block/mmcblk0p27
adb shell tune2fs -o journal_data_writeback /dev/block/mmcblk0p26


mmcblk0p27 is my /cache partition
mmcblk0p26 is my /data partition

Yes it was covered but not answered.

I found if you only push the
/system/etc and /system/lib files (leaving out /system/bin) it will still predict names in
stock SMS app. Still seems a bit snappier when scrolling too...

I see that there is know a universal v7. Is this compatible with our phone yet?

The universal v7 tweak is compatible just make a nandroid just incase and if it doesn't flash right just push the files with root explorer or super manager.

Very nice, I'm running v7 on VU 2.37 and it is smooth as silk even with me running under clocked to 1017. Just wish this was available for my Acer A500 tablet

I was having same issue on my g2 with this tweak. It kills auto search feature on sense roms.

Don't install the libsqlite.so file (under /system/lib/libsqlite.so). Use winRar and erase it from the zip, or just don't install it if you used root explorer to cut and paste... Works for me

    These are some tweaks created by dsexton702 that offer you a generous performance boost in I/O and giving you the newest fugu mod 3.1. This is a fast growing tweak and needs to be shared with everyone who can benefit from it

    This has been tested on MT4G

    download the U.S.A.Sv6

    Oh wow thanks man. You are quite the dev god in the SGS4G forums. So I know this is some quality stuff that people should give a shot.

    BTW, do you wipe cache and dalvik before flashing or just straight up flash it?

    I had to push the files to the proper location then fix permissions on unity 2.35

    How do I reverse this tweak?

    Reflash your ROM without wiping your data
    That should work and the mod will be removed however any other mods you had will also be removed so you will have to flash them again

    how did you flash it ??

    manual push or flash thru clockwork recovery??

    I am also on Virtuous Unity 2.35.0

    I flashed mine through clockwork and it worked fine
