These steps are intended for use on the stock Droid X2. I'm sure they will be close to the same on other phones, but if your phone is not a stock Droid X2, know that the steps may be different or you may get unfavorable results. Always backup anything you don't want to lose.
Before even considering this, READ ALL THE STEPS. Then READ IT AGAIN.
There are two tweaks recommended here: V6_Supercharger and SD Speed Increase.
Requirements for V6_Supercharger:
1. Rooted Phone (Gingerbreak 1.20)
2. Script Manager (free on Market)
3. BusyBox 1.18.2 or earlier
NOTE: I haven't confirmed the script works on 2.3.4... You may want to use the latest version of the script if you have 2.3.4
Installing/Using the script:
1. Install BusyBox. There are a number of ways to get this... it comes as part of Titanium Backup, for example. If you're not sure if you have it, or not, you can use BusyBox Installer (free on Market) to detect whether or not you have it and install it if you don't.
- Note: BusyBox Installer tells you which version you have installed on the main screen after it loads... it should be in a list that starts with "Your device is Rooted"
- Note: Make sure you don't install BusyBox 1.19 or anything newer than 1.18.2
2. Download the script. Save it in a place where you'll be able to find it.
3. Launch Script Manager and find the downloaded file (usually in /mnt/sdcard/download). Long-press no it and select rename, then delete the .txt from the end. You should have a file named "V6_SuperCharger_for_Android-update8.sh"... Press once on the script file to load it into Script Manager, check the 'Run as Root' box (DO NOT select "Run at Boot") and push "Run" to execute the script.
4. The script will run and ask for a speed. Touch anywhere on the screen to open your keyboard. Type 1 if this is your first time running the script, 0 if you're a fast reader or you are in a hurry. Next, it lists 17 options and gives an input prompt. Type 8 and push Enter. (This selects the called MegaRAM 1 preset, but feel free to try others, if you're so inclined)
5. Once script finishes, type 17 and push enter to end the script. Push the phone's Menu button and select 'exit' to return to the list of scripts.
6. Pushing the phone's Back button should bring you to a file browser. Push the '..' line (second from top) until the top line reads '/'.
7. Push the phone's Menu button, push 'More' and then 'Config'. Check the box 'Browse as root'. Push the phone's Back button to return to the file browser.
8. Browse to /data and select '99SuperCharger.sh' (This script was created by the first script and makes sure the settings from the first script are re-applied on boot)
9. Select both 'Run as root' and 'Run at boot'. Push 'Save' and then 'Run'. If it says "Exit code 0" at the top of the screen, the script ran successfully. Any other Exit codes should be reported.
10. Almost all the settings are now in place... but reboot your phone to get the last ones implemented.
11. After reboot, launch Script Manager and run V6_SuperCharger_for_Android-update8.sh (the first script). Select 0 at the first prompt, look for the current minfrees values... it should say "Launcher is HARD TO KILL!" and "Current minfrees = 6, 12, 40, 60, 80, 100". If the settings are correct, type 17 to exit and you are done. If not, re-read steps because you missed something.

Requirements for SD Speed Increase:
1. Rooted Phone (Gingerbreak 1.20)
2. SD Speed Increase (free on Market)
Configuring SD Speed Increase:
1. Open the app and adjust the memory slider to 2048
2. Check 'Set on every reboot'
3. Push the red button
4. Reboot the phone
Advanced: 3G TurboCharge
- I'll post full step-by-step instructions soon, but for now, here are two more scripts from Zepplinrox that will boost 3G performance... (Forum Post) Run 3GTurboChargerInstaller.sh and 98KickAssKernelTweaksInstaller.sh once each (Hint: Don't forget to remove the .txt extension). The second script creates this boot script: /system/etc/init.d/98kickasskernel, so you will have use this thread to get init.d created (Side note: I haven't been able to get it to actually run the scripts that are placed in init.d... we're stuck with Script Manager for now). Run all scripts as root, obviously.
Questions, Comments & Corrections are welcome!
To Do:
Update SuperCharger to update7 (need to test it myself first)
Test and implement AutoStart script
Edit:
06/27/2011 - Removed ro.Home_app_adj tweak. It's handled by the SuperCharger script.
06/27/2011 - Updated SuperCharger script instructions to use v4 of the script.
07/14/2011 - Updated SuperCharger script instructions to use v5 of the script.
07/25/2011 - Added BusyBox requirement to the SuperCharger script.
07/25/2011 - Updated SuperCharger script instructions to use v8 of the script. Rewrote most steps for improved clarity.
08/19/2011 - Updated 3G and Kernel links.
Using it now... Cant see a major difference but I can tell some things are faster... and havent had any reason to kill any apps because the phone starts to get sluggish so IMO thats a major plus and a sign that it is working...
Oh yeah... use option 9! Megamemory device....

What does the script say those numbers mean?
The 1-3 settings are just setting the scroll speed of the text when the script runs. I personally like to set it to 1 (fastest) but it really doesn't matter. 3rd gives you a chance to read everything.
Works, like a charm, now if i wanted to get rid of it would it just be going back through the steps and undoing what i did?

No, all you have to do is uninstall script manager and reboot. Deleting the scripts is optional.

Requirements for V6_Supercharger:
1. Rooted Phone (Gingerbreak 1.20)
2. Script Manager (free on Market)
Installing/Using the script:
1. Download this ZIP and extract the script to your sdcard.
2. Load the V6_SuperCharger_for_Android-update4.sh script into Script Manager and check the 'Run as Root' box (DO NOT select "Run at Boot"). Push "Run" to execute the script.
3. The script will run and display a list of 16 options and a prompt. Touch anywhere on the screen to open your keyboard. Type 9 and push Enter. (This selects the option called MegaMemory Device)
4. Once script finishes, type 16 and push enter to end the script. Push the phone's Menu button and select 'exit' to return to the list of scripts.
5. Pushing the phone's Back button should bring you to a file browser. Push the '..' line (second from top) until the top line is '/'.
6. Push the phone's Menu button, push 'More' and then 'Config'. Check the box 'Browse as root'. Push the phone's Back button to return to the file browser.
7. Browse to /data and select '99SuperCharger.sh' (This script makes sure the other script runs on boot. Otherwise you would have to do steps 2-5 everytime you boot your phone)
8. Select both 'Run as root' and 'Run at boot'. Push 'Save' and then 'Run'. You will most likely see 2 errors at the end of the 99SuperCharger script... this is expected.
9. Reboot your phone, but you might already notice a significant difference in speed and zero redraws from your launcher.
10. After reboot, launch Script Manager and run the V6_SuperCharger_for_Android.sh script, but this time don't select any options just look at your current settings and make sure they are the same as the Step values you put in. Right under the list of options, it should say: 'NOTE: Current minfrees =' If they are correct, type 16 to exit and you are done. If not re-read steps because you missed something.

What are the values that it sets? I currently am running the V6 script and unless this is a newer version my option 9 is called "Gaming settings". At any rate I did option 10 and set values at 6,12,75,125,150,175. What does this set them to?
disregard my previous post. I ran it and found they are the same settings I have been using. Thanks for the updated script though.
is their a script dev thread where updated scripts are posted
THANK YOU!
I was about 10 mins away from calling VZW and telling them to take this back and send me my original X back... I wasn't able to get ANY Ver. of Pandora to play or even Slacker half the time. The complete phone would freeze ALL the time to the point I could not do anything unless I performed a Battery Pull to hard reset.
This fixed ALL my issues. I don't even have the 1-3 second wake delay I was experiencing before. So far so GREAT!! As I type I even realize that while Pandora is playing and the phone is charging it is not getting nearly as hot as it was before? I don't care why it's working better now, but I'm glad it is!
I can't wait until we can get a decent rom with these fixes already in place! I loved Liberty on my old X. I miss it!

The end of the OP has the link.
This's pretty slick. While I haven't noticed huge gains in most areas, due to having cleaned and optimized my phone, the whole thing just seems to run with extra smoothness. Also, there's no more delay when waking the phone.

I ran this script on my phone and couldn't be happier. Stock I'd get about 115mb ram free on ATK. After root and de-bloat I topped out at 170. After this script, 220+!!!

This is a godsend!
Thanks for creating this thread and providing the most excellent script for memory mgmt. I've just installed it on my DX2 and boy, does it fly! I now see 130m+ memory free whereas before it would bounce between 50M-90M. Many thanks! I will run the remainder of this week and see if there are other impacts.
I do have one question, however, since I'm a newbie to all this: can I now remove the ATK application and disable the native Task Manager application with this script now in place? Or should I keep these as add'l failsafes?? Please advise and thanks for all the great info on this forum!

Does this increase benchmark scores at all? I know they don't mean anything but I think we can all agree, they're fun.
Also does this JUST manage memory or does it do other things as well?
Sent from my SCH-I500 using XDA Premium App
In my limited and completely amateur testing, there was no noticeable improvement in benchmarks... but I'm sure mileage will vary. You should seek out Zepplinrocks (the scripts writer) for a better answer.
I am sure this is a stupid question, but I'm a droid Newb. Is it nessicary to have the script manager app constantly running once you have already ran the script? Or is it good to go once I have exited it the last time? And after rooting, and running this script my weather widget keeps on saying i am in rockport il. And I'm not.... any suggestions?
When I click the Zip to download V6 on my phone it say "download unsuccessful"
And I have done these:
Requirements for V6_Supercharger:
1. Rooted Phone (Gingerbreak 1.20)
2. Script Manager (free on Market)
Ok..
I can push the modules into the appropriate folder on the phone and I can run the commands which add it to the cpu governer selection (it took me awhile to realise I had to run 'su' command first ooops!).
However, upon rebooting the smartass governer dissappears from the selection tab and returns to 'ondemand' even if restore upon boot is selected. I assume the module is only temporarily loaded via the 'insmod' and 'echo' commands.
So I pulled the hw_config.sh and added the commands to the end under a new #tag (for ease of keeping things seperate). The same commands listed in the smartass thread. Pushed in back to the phone, But... smartass still wouldn't load and the cpu governer switched permanantly to 'performance' - even when I removed the commands from the config file
Had to restore my cwm backup to fix the issue.
I noticed that the config file makes reference to the ondemand module so wondered if this causes conflict with the smartass one??
I'm fairly new to modding stuff. Anyone got smartass working on gintonic1.3? Can they tell me the proceedure they used?

This Post Doesn't Specify For Froyo Or Gingerbread Users. It's Up To The User, And I'm On Gingerbread And I Find All 3 Beneficial.
Now that we have the init.d hack will the kickasskernal with the IO tweaks work? Or should I just use the IO tweaks that come with navenedrob's script?
I Vote You Should Try It And See If It Works. Make A Backup First.
It boot looped...........
Do I have to sbf? Or could I just use the nandroid?
Throw The Phone Out Now. You Royally Messed Up. Geez Leave You Alone For One Minute And Look What You've Done. Nandroid Is Just Fine, No SBF Necessary.
WAAAAHHHHH no fair.... oh look it rebooted.....
So yea I am gonna try to use the IO tweaks from navenedrob's script as well as the cpu tweak from his script oh on top of the SD read ahead one. Those should work well with supercharger and kickasskernal I think. Those do not touch the cpu freq right?
I Don't Have Any Reason To Believe It Would.
Awesome, everything is working great.
My cpu is set to 1000 min and max. Sd read ahead is working but umm how do I know if the IO tweaks are working?

This Was Actually A Toss Up, Because Zep Started A Thread In The General.
i tried the scripts on p3 and it actually made it use marginally more ram and it was glitchy. i dont remember what numbers i used but i got them from this forum somewhere. either way when i tried to undo it i got a reboot loop so i sbfed and went back to p3. after looking into it some more ive read some places that you dont need this if you arent running froyo. any truth to this?
I Don't Think It's Been "Proven" But Rather A Preference. I'm Using All 3 On P3's Along With Various Other Tweaks I've Taken From Others. I Have 40 Running Apps With 100Mb Of Ram And My Phone Is Still Lightning Fast. So My Conclusion Of "Truth" Is These Help Tremendously. On The Other Hand A User Like Yourself Claims It's Worse. I Hope That Helps In Understanding What You're Asking.
so what you are saying is that its personal preference and doesnt really matter that much?
Lemme note here, I deserve no credit, all code and all work was done by Eugene_373 and anyone mentioned below, this is simply a share from the T-MOBILE GALAXY s2 section of XDA, I have fully tested this app and found it to be working wonderfully on my SGH-I777
I love eugene's deving hence the share I hope you all enjoy if this has some way helped you in anyway go over to eugene's profile donate/thank him
App Version:
CPU Sleeper
~Free to all XDA Memebers
~ Must Be Rooted to use App
What is it?
Its a fairly simple App that will put CPU 1/2/3 OFFLINE when the screen turns off. Once the screen comes back on, it will allow CPU 1/2/3 back ONLINE.
How does it work?
Since we have Dual & Quad core CPUs, we have a CPU 0 and a CPU 1/2/3, core 0/1/2/3, while the screen is off we really only need to have 1 core active "CPU0", this App will make sure CPU 1/2/3 shuts off while the screen is off, then resumes normal usage when the screen comes back on.
Compatibility?
Works with any Dual Core & Quad Core Devices!
~ICS
~Gingerbread
Battery Saving?
Battery savings all depends on Usage & idle times.
App Download: CPUSleep.apk
Version 1.5 Release Notes:
~ Battery Drain issues 100% Fixed
~ Screen on Lag 100% Fixed
~ SU issues 100% fixed
~ Auto-Start on reboot 100% Fixed
~ Fixed Auto-Start killing Cell Service
~ Su Request on Screen Wake Fixed
~ Debugging enabled for those wanting to check if it's working.

Script Version!
Code:
This time I present to you a script that will in theory (and so far for me, in reality) save us some battery without having to risk our hardware with undervolting! I present to you...
[B]CPU Sleeper[/B]
[U]What is it?[/U]
Its a fairly simple script that will put CPU 1 OFFLINE when the screen turns off. Once the screen comes back on, it will allow CPU 1 back ONLINE.
[U]How does it work?[/U]
Since we have dual core CPUs, we have a CPU 0 and a CPU 1, core 1 and core 2, while the screen is off we really only need to have 1 core active, this script will make sure CPU 1 shuts off while the screen is off, then resumes normal usage when the screen comes back on.
[B][COLOR="red"]WARNING! READ THIS![/COLOR][/B]
This script relies on init.d OR script manager! CM9, for some reason, tends to run this at the exact same time it runs some other script (I forget atm which) and it will clash, causing no boot! CM9 users MUST use the script manager version install! Flex Reaper appears to work fine with it as init.d. I strongly urge you to use the script manager version of this, NOT the flashable version. Always make a nandroid backup before modifying the system, including this!
[U][COLOR="Red"]Instructions[/COLOR][/U]
Available in 2 versions, script only version which you can place wherever you want and run however you want, or a CWM/TWRP flashable zip that will place the file for you in /system/etc/init.d and set permissions.
[I]Version 1: Flashable[/I]
Same as any of my flashable releases, I did most of the work for you!
Make a full backup
Download to external SD card
Install from SD card
Pick the cpu sleeper zip file
it'll be almost instant
reboot
Shouldn't be any need to clear caches or anything like that.
[I]Version 2: Script only[/I]
This can be run in 2 ways, via init.d support, or via script manager. Both are pretty similar, and can be done a number of ways, however this is the basis of how.
[U]Init.d supported kernel:[/U]
Make a backup!
Download the script file, making sure no extensions get added onto the file. Copy the file to /system/etc/init.d and set the permissions to the following:
XOX
XOX
XOX
Once done, reboot the system, and it will take effect when your system is finished rebooting.
[U]Script Manager[/U]
This method is probably the better method, and should work with any kernel/ROM. Download the script file, making sure no file extensions get added, and copy it to /system/etc. Set the file permissions to:
XOX
XOX
XOX
Once done, load up script manager, select browse as root (if it isn't already set from the crossix mod method in the guide) then browse to /system/etc and select the script file S98cpu_sleep, then select ROOT and BOOT options. After this is set, reboot system.
[U]What do I do if I can't boot after using this?[/U]
You made that backup, right? Ok, then here is what you do.
Hold the power button until the tablet powers off
Press and hold the volume down button, next to the screen lock switch
Press and hold Power (while holding volume down)
Once the recover kernel message comes up, release the buttons
In CWM go to advanced, mounts, mount system, then format system
In TWRP, go to wipe, then wipe system
In CWM go to restore, advanced restore, restore ONLY system
In TWRP select restore, then uncheck all so ONLY system is checked
After restoring system, wipe cache and dalvik cache, then reboot system.
System should boot normally.
[B]Downloads[/B]

Hotplugging and sched_mc are kind of synonymous. The difference is that sched_mc allows you to force a particular pattern of behavior (1 = fill 1 core first, 2 = activate both). This app attempts to force 1 core offline when the screen is off. It's kind of like an extreme version of sched_mc = 1 in that it doesn't allow both cores to be activated. However, I'm not sure if it is capable of preventing the second core from coming online. It may check periodically and subsequently turn it off. I don't think it would have much benefit on our devices; our hotplugging is competent and sufficient. I suppose anything is worth trying though.
looks interesting!
Every now and then i get cpusleep has been granted superuser permissions when the screen is on and im surfing the net or playing a game.

Does it work fine with setcpu ?
Hello everyone,
I'd like to get informations about our possibilities to make root, overclock (underclocking) and expand swap file.
1) Root - is it possible to root the phone without using kingroot?
2) Expand SWAP file - in Lollipop size of swap file is 200MB, I'd like to expand it, is it possible?
3) Underclocking - while I've tried to do underclocking my phone use only one core of 4 available, I'd like to underclock cores from 787 MHz to 300 MHz minimal frequency without losing multi cores support.
Regards.

1) check in the dev section, there's a guide for rooting with kingroot for then replacing it with su after, also check the flashable 5.0 LG ROM thread in there, saw someone talking about su
2) The 200mb is zram not actually a swap file. You can expand this, just search ram expander or swap in play store, and look through the apps.
3) Go into a build.prop editor search for min and find the one with minimum frequency now change the 787000 part into 300000. Also all four cores doesn't run constantly on the same time, they're activated and used as needed(i believe)
