Not that it really needs it... but... :D

Confirmed Roms:
VisionX US N3
TweakedN3 3.9+
HyperDrive RLS5+
DirtyUnicorn
LiquidSmooth
CM11 Nightlies

Let me know what roms you are using this on so I can add to this list please...

Make sure the rom you are on has the latest busybox installed.

Flash in whatever recovery you have, and it'll do the rest. This should work any Samaung device that are Android 2.3 and up, I only have devices that are HoneyComb and up, and it's been tested on them, and works great on them... TEST and USE AT YOUR OWN RISK

What does it do Kev?

  1. Vacuum's SQLite every 4 days
  2. Zip-Aligns all User Data APK's every 3 days (if you choose)
  3. Cleans Caches, Logs, Tombstones, etc... every week
  4. Tweaks Your systems I/O
  5. Makes your Mobile and Wifi Networks faster
  6. Bumps your Wifi scan to every 300 seconds (battery saver)
  7. Enables some Dalvik VM Flags to optimize the loading and executing of all your apps
  8. Enables Dalvik to execute in the Java JIT
  9. Bumps your Dalvik Heaps a tad (let's face it... we got 3G of RAM, so why not?)
  10. Moves your Dalvik to your /cache partition, leaving you a bit more room for more apps
  11. Removes ext4 Journalism on your internal system storage (big time performance boost)
  12. Forces your Launcher into Memory (yes this will take up a bit more RAM, however, your launcher will be much more responsive)
  13. Remounts your devices system, data, and cache partitions explicitly, no updating timestamps, and asyncronous I/O calls
  14. Tweaks your External SD Card read-ahead
  15. Calibrates your Battery if it needs it
  16. Enables true init.d support to devices that are bootloader locked
  17. De-Bloats Note 3 Devices of Samsung, GApps, and Carrier Bloatware. NOTE: Don't bother using it if you've flashed a Note 4 or S5 rom
  18. Logs most actions to /sdcard

But, why do I need it Kev?
In all honesty, you probably don't. Personally I wanted a little more oomph outta my device, so here we are... Not that there's anything wrong with the default, but me being on a locked bootload on my S4, I didn't get the luxury of being able to flash custom kernels to suit most of these needs :)

This is awesome Kev, how can I thank you enough?
:)
Hit the thanks button.

Can I run it manually?
Sure. Grab a terminal emulator and type the following.
Code:
su
sh /system/etc/init.d/10KevsTweaks
sh /system/etc/init.d/11KevsDalvikMover
sh /system/etc/init.d/12KevsZipAligner

As with any mod you do to your device, make sure you make a full backup before you do anything, and as always... YOUR DEVICE'S WARRANTY IS NOW VOID
You may use this, if you use it on a device other than a Samsung, make sure you edit the init.d script to match your devices '/system', '/data', and '/cache' partitions

UPDATE 10/23/2014: - Version 2.0.3
- Fixed build.prop modifier (FINALLY!!!)
- - Backs up original
- - - If your boot hangs on you after about 5 minutes, reboot into recovery, delete /system/build.prop and rename /system/build.prop.bak to /system/build.prop
- Added latest sqlite3 binary

UPDATE 10/23/2014 - Part Duh: - Version 2.1.0
- Fixed build.prop modifier (FINALLY!!!)

UPDATE 10/27/2014 - Part Duh: - Version 2.0.3n
- Removed De-Bloater for Note Version

UPDATE 11/11/2014 - Version 2.0.5
- Added De-Bloater
- Misc. Filesystem Tweaks
- Updated to latest Bash Binary

UPDATE 11/12/2014 - Version 2.0.6
- Fixed De-Bloater

UPDATE 11/12.5/2014 - Version 2.0.7
- Added in some extras to the debloater. Should remove associated libraries to some of these apk's

UPDATE 11/23/2014 - Version 2.0.8
- Added in some I/O tweaks to rootfs, tmpfs, internal & external storage
- PLEASE DO NOT MODIFY MOUNTS DURING FLASH IF YOU ARE USING F2FS

If you encounter any errors during or after the install, please save the Log. It's the hidden button right next to the Finish button in the installer. Once saved, PM it to me.


I cannot stress enough how important it is to make a backup of your system before installing this, as it can bork your device! YOU'VE BEEN WARNED​

Same thing is happening like the auto rotate fix you made. Keeps getting stuck when I try to flash it m says it's using aroma which I can't use cuz I'm on safestrap with ATT. Am I doing something wrong?

Does it depend on firmware or tw vs. Aosp? I'm still on darthstalker thanks bro.
I wouldn't think so.

To be safe for now, flash it without using the build.prop mods... do a nandroid backup, and then reflash with the build.prop mods.
Seems that those are the odd-balls with this for some reason still... though I have it setup to delete the existing lines, and write my tweaks in...

Also, next update, I am taking out the odexer... and probably the update after I'll be putting in the de-bloater... still sifting through the apks/ and associated lib files so it truly and smartly debloats :D

    Nope. Didn't work. After flashing it went all super laggy and got the gapps notification. Had to restore. Worth a shot though. Tried it on Note 3 T-Mobile running cm12 5.0.1 Lolligang. I reflashed the gapps just to see if that would work and it didn't really do anything.

    Flashed fine on my LG G3, LOL! I used your mods before on my old S4 so I did a nandroid and just flashed 2.0.8. I didn't choose build.prop edits or to debloat and flashed fine and no errors at boot. Responsiveness of home screen already feels a little snappier. Thanks man!
    LOL NICE!!!!

    I just installed 2.0.7 on my D2LTE (VZW Galaxy S3) running the 11/10 AICP ROM. Works great! I clicked all the options except debloat.

    First boot had force closes galore, which seems to be normal when messing with the dalvik of this device/ROM. But once I let it sit for a few minutes and then rebooted, all the force closes went away and it's been smooth sailing since. Hopefully this will help out battery life a bit.

    Thanks for the mod!
