[WIP] Just in time compiler for Nook Color - Nook Color Android Development

There seems to be a lot of mystery surrounding the release timeline for the official Froyo (2.2) update for the Nook Color. One of the biggest advantages that I've found using Froyo is the serious speed boost, compliments of the Just-in-time compiler (JIT). Many other Froyo features are directed primarily at mobile phones and aren't particularly relevant to our device. That said, I know that JIT was slated for release on 2.1 but wasn't ultimately implemented until 2.2. The good news is that JIT does run on 2.1 and isn't that difficult to implement (It does NOT require a special kernel or anything). I've done some research and am going to start working on getting the JIT to run on Nook 2.1 tomorrow morning once I sober up. I started this thread in order to see:
1. Is this feasible?
2. Is there an interest in this?
3. If people would be willing to test this
4. If anyone has some input on how to get started
5. If others will help me develop an easy method to get this running for others
While I certainly respect and encourage the developers working on the community version of Froyo, we all know that it's not ready for prime time. This should give us many of the advantages of Froyo without having to sacrifice daily usability.

that would be cool, i don't see how that would not be possible but then again i am not a dev,... I know threre is more to it that just flash 10.1 but HTC had there own version of it while motorola didn't on there 2.1 OS

It's possible, follow that link. Cyanogenmod had it on my Nexus One when it was 2.1. I am like 90% sure it can be done I need to work on it and I will tomorrow night just wanted to get people aware of this and looking into it.

Would be awsome. JIT and Flash are all I am really missing.

I don't know how helpful it is but some of the old evo 2.1 roms had jit compiling. Maybe you could look at those. Damage control 3.5 i remember specifically having it.

you can use Skyfire as a browser for the flash part

Honestly it probably wont work very well. When the Droid 1 first came out many devs worked on enabling JIT on 2.1 for it. It worked but with major stability issues. And it wasn't only the D1 having stability issues. 2.1 just wasn't written with JIT in mind originally, which is why 2.2 was so huge.

SWM is right. I installed it on my Droid in March of last year and it was fast, but ultimately proved to be unstable. The following is post I made about JIT. It was in March of last year (the links are surely not functional now as I think those websites are gone now). Also, ignore the optimism in the post because the stability did not last:
I’ve been running Bugless Beast roms since the end of January.
Everything that follows is all based on work done by t3hSteve. Here’s his description of the process: He rebuilt the file dalvikvm with JIT defined “and then copied libnativehelper, libdvm, and dalvikvm to my phone. Added dalvik.vm.execution-mode=int:jit to build.prop and rebooted”. After reading that short post, I started reading and googling until I learned how to do the same using his modified dalvikvm file. After reading (http://alldroid.org/viewtopic.php?f=210&t=1673 ) and learning that some folks that are running JIT are still having problems with browsers closing and with some force closes. I, on the other hand, knew that JIT had run well on my Droid with BB7.7. After all the reading, I was more convinced than ever that having Animations turned off was a key to successful operation with JIT. I have no technical reasons to support this position other than it seems that a lot, not all, but a lot of people that are having problems with JIT enabled are also mentioning how much they like Live Wallpapers. So taking those two tenuous data points (1. My Droid ran fine with 7.7 and JIT enabled and 2. I have animations turned off and most folks obviously do not due to the fascination with Live Wallpapers.) I decided to go for it. I then enabled JIT on my droid.
The results are pretty good so far. Before enabling JIT I would mostly get 159 - 179ms benchmarks. With JIT enabled I’m getting at lot of reading in the 130 - 150 range. I downloaded Linpack and promptly started getting readings in the 11’s. My best so far is 11.924 Mflops/s. So far so good. I’ve had absolutely no issues at this point. I’ve been running with JIT enabled for about 4 hours so far. It’s hard to operate the Droid and type with my fingers crossed. 
To accomplish this I added a line to the end of the build.prop file and replaced libdvm.so and libnativehelper.so with copies I got from t3hSteve. Here’s the procedure I followed:
1. Make a full Nandroid backup and save a copy of it on the computer.
2. Download the file “vmlibs.zip” here http://alldroid.org/download/file.php?id=1374
3. Create a new folder on your sdcard named: JIT
4. Extract vmlibs.zip to the new JIT folder on the sdcard.
5. Open the JIT folder and create a new folder in it named Backup. This is where you are going to keep your current files that are going to be replaced: dalvikvm, libdvm.so and libnativehelper.so
6. Disconnect phone from Computer. The following steps are going to be done with Root Explorer.
7. Go to /system/bin and copy dalvikvm.
8. Go to /sdcard/JIT/Backup and paste dalvikvm there.
9. Go to /sdcard/JIT/bin and copy dalvikvm.
10. Go to /system/bin and select the mount RW button
11. Paste dalvikvm there – answer yes to the overwrite question.
12. Long press the new dalvikvm file and choose Permissions and check every box.
13. Press the Mount RO button.
14. Go to /system/lib and copy libdvm.so and paste it in sdcard/JIT/Backup.
15. Go to /system/lib and copy libnativehelper.so and paste it in sdcard/JIT/Backup.
16. Go to /sdcard/JIT and copy libdvm.so.
17. Go to /system/lib and press the “Mount RW” button.
18. Paste the libdvm.so file there. Answer yes to the overwrite question.
19. Go to /sdcard/JIT and copy libnativehelper.so .
20. Go to /system/lib and paste the libnativehelper.so file there. Answer yes to the overwrite question.
21. Press the “Mount RO” button.
22. Go to /system and long press the build.prop file.
23. Select “Open in Text Editor” in the window that opens.
24. Open your physical keyboard and scroll to the bottom of the file and enter the following:
25. Dalvik.vm.execution-mode=int:jit
26. Press the phone’s Menu button and select “Save & Exit”
27. Reboot
------------------------------------------------------------------------------
Here's the adb vesion (don't know the source, it wasn't me):
abd pull /system/build.prop build.prop
Open in WordPad and add
Add as the last line:
dalvik.vm.execution-mode=int:jit
SAVE
adb shell mount -o remount,rw /dev/mtd/mtdblock4 /system
adb push dalvikvm /system/bin/
adb push libdvm.so /system/lib/
adb push libnativehelper.so /system/lib/
adb shell chmod 755 /system/bin/dalvikvm
adb push build.prop /system/
adb shell reboot
-------------------------------------------------------------------------------------
I am not a dev and have no idea if any of this old stuff will help with the NC, but there it is!!
Good luck.

To Geezer Squid: Great find, I've put it into my blog, thanks. I have a collection of NC quirks there -- with probable ways to improvements. Yours should work like a charm.
To brashmadcap: Excellent move! Hope your next "Next up" after system-wide copy-paste would be hardware assisted 2D/3D drivers and video overlay and/or VOME engine out of AOSP 2.3:
Now all it may take is searching for OMAP36xx's JIT (dalvikvm and libdvm.so and libnativehelper) for A2.2.1 (or maybe 2.3 if already available and different from A2.2.1's). Next step (or preliminary step?) would be getting rid of all UI "animations" and "Live Wallpapers" crap that were designed before a good JIT compiler appearance.
While digging in TI OMAP36xx (or maybe even in TI OMAP4430) and Droid X/2 repositories for better JIT, I would ask to pull and try better (later) 2D/3D drivers, the newer NEON framework and better (read: working) hardware assisted overlay (HQ YouTube is obviously using it today, why other/stock video players don't know it even exists? where's the usual "stagefright" fallback options of build.prop?).
Then flash_for_2.1.apk (Flash 10.1) will simply work, I hope.

X10a 2.1 update issue & workaround *Telstra*

Hey there guys,
I have been one of the users sittin here in the background hacking away at this phone, so thought i would report back on what it is I have found
After applying the Jit Optimiser v2, once you have finally applied the 2.1 X10a, and it has run through, and reboots, you have now got an X10i
So naturally, for us telstra next G users, Ive been working on something here, to enable us to still keep the X10a as it is
Plus I am looking at other tweaks, and currently wrestling with a few system files, so I will be happy to share it once i have finally finished it, which should be in the next few days
I will mention, this script has the Jit v2 optimizer in it and a few of my parts in it (files I've modified), so credit to the devs/ppl who made their respective section of this script possible
Progress: Build.prop changes = DONE
Init.rc changes = IN PROGRESS
My background has been for the past 5yrs or so, in linux/bsd debugging/optimization, so fooling around with android is a natural process for me
Just leave a note in this thread if you would like to help me fine tune this script, and are a Telstra Next G User. I can modify it for other users, but i will need to find the forums post which has all the country codes in it
Peace Out
Nutterpc
I'M a telstra user and happy to assist
Soon as i get home i'll upload the current script, currently at the chiropractor
Sent from my X10 using XDA App
Never stay up too late, lol, I fell asleep when i got back from my appt
Anyways man, currently waiting for the files to finish uploading
Anyways, here goes with the file, finally waited for it to upload
This has the build.prop changes included, I'm still working away at the init.rc changes currently, that might be a few more days
http://www.mediafire.com/?qt89vw7quoor6sl
Let me know how it goes for you man once you try it
STEPS REQUIRED:
1) 2.1 X10A Firmware must be loaded http://forum.xda-developers.com/showpost.php?p=6514692&postcount=2
2) Root Access must be obtained http://forum.xda-developers.com/showthread.php?t=833954
3) ADB must be on your pc, either full install or files http://forum.xda-developers.com/showthread.php?t=502010
4) Best have it, just for safe measure, Java: http://javadl.sun.com/webapps/downlo...BundleId=39494
Once you have all of that, go to Start -> Run -> type cmd and hit enter
Make sure you have your files in the same directory, copy over the adb files, enable usb debugging on your phone, and on windows, type adb devices, to make sure your phone is connected and adb recognises it, then hit adb shell, type su, and keep an eye on your phone for a Superuser prompt, allow it
That measure above is mainly for saving you in future with outher mods you will no doubt make to your phone
All thats left to do, is just double click on the file install, and let it run its business
You will find upon reboot, it no longer turns your 2.1 X10a into an X10i, which is the main gripe quite a few users had
If anyone else here with another provider would like me to add extra versions of it for their respective country, just add on this post with your country code and i'll do up some moire customised versions for you
Hi Mate
Do you have a nfo file or something?
I would like to know features/benefits etc?
Im currently sifting thru the init.rc file atm, made some changes to it, but as to nfo file, not yet, no
Main changes to the build.prop were to change the country code & a few other little bits
Im currently sifting thru the init.rc file atm, made some changes to it, but as to nfo file, not yet, no
Main changes to the build.prop were to change the country code & a few other little bits
OK, got most of the changes done to the init.rc, so I will upload it once i get back home from work, currently on break, lol
Peace
Changes to the init.rc file are now done, just need to finish modifying the file so it can install properly

[ZIP][DEV][ROM] Nookie Froyo 0.6.8 (02/15) CWM flashable!

Nookie Froyo 0.6.8
is a development build of Froyo 2.2.1 for the Nook Color.
ClockworkMod flashable! - info below, please *read carefully* before flashing!
This build is near-AOSP and contains almost no extra software not deemed required for the device to function normally.
It is pre-rooted with SuperUser, busybox, SoftKeys v3.07, and ROM Manager 3.0.0.5 however.
The eventual intention will be a build that other devs and users can easily fork and create their own custom builds, themes, roms, etc.
** THIS IS A DEVELOPMENT BUILD **
Use this at your own risk! Myself, XDA, and NookDevs are *NOT RESPONSIBLE* for anything that happens directly or indirectly related to this software!
We're approaching a daily driver! Most things work now, including mp3 and video playback. Post any bugs you find here!
I'd like to thank all the nook color devs involved in getting to this state, testing, documenting, etc. We've got an amazing group of minds behind this device!
INFO
The microSD card image contains 4 partitions:
/dev/block/mmcblk1p1 : boot (fat32)
/dev/block/mmcblk1p2 : system (ext2)
/dev/block/mmcblk1p3 : data (ext3)
/dev/block/mmcblk1p4 : sdcard (fat32)
Use these partition IDs when following guides that require mounting/remounting filesystems.
What's Working:
MP3 playback
Video playback
Youtube, Pandora and other mp4 streaming apps (apps not included)
Accelerometer!
Wifi (adhoc + infrastructure!)
Graphics acceleration (LWP!)
Sound
Browser
Mostly working
Lockscreen is wrong size - REBOOT to fix
Not included / Not working
gapps ( gmail, youtube, maps, etc ) - can be installed, youtube fixed!
Bluetooth
FM radio
This build was created using the B&N kernel sources for 1.0.0, Omappedia's Froyo source ( currently RLS27.9.0.RC0 ), and binary drivers from TI for wireless, SGX530 acceleration, and DSP codecs.
Download:
This SD image requires a 2GB microSD card! Bigger is OK, smaller is not ok!
Note: if you wish to use a larger microSD card, you can use a partition editor to increase the size of the /sdcard partition (partition 4, fat32) *after* writing the image to your card.
Simply unzip this image and dd the file to your (empty) SD card, just like nooter.

This archive also contains an uncompressed ramdisk image which you can easily edit, package, and copy to your boot partition.
ClockworkMod Flashable ZIP!
*IMPORTANT*
- please wipe data/factory reset if you're coming from B&N stock firmware or another rom!!
- please see other threads about installing and using CWM recovery - keep this thread to NF issues please
- this has been tested only using CWM 3.0.0.5 downloaded from market, be warned it may not work with IOMonster's kit or other versions. Let us know if you try and it does!
- replaces kernel and ramdisk - if you were using an alternate kernel you'll need to reflash it.
- This will irrevocably erase and replace the software on your eMMC! MAKE BACKUPS BEFORE FLASHING, you have been warned.
If you're upgrading from an older version of Nookie Froyo, you should not have to wipe - however if you do have problems *wipe data* and try again.
*IMPORTANT* - this zip does not require any extra steps such as formatting /boot, changing system permissions, and does not replace or remove CWM. If you are coming from a ROM that required these extra steps and are having issues, *please post your questions there* so the dev can be prompted to correct those issues properly.
If you're coming from a rom that doesn't support CWM properly see the following thread:
http://forum.xda-developers.com/showthread.php?p=11437545
Installing /system will take some time, and the progress bar doesn't update in realtime; you haven't 'locked up', just be patient as it may take a few minutes.

Do not try to Format SD card from Settings -> SD & Phone storage!
- there is currently a bug that causes the system to format the /boot partition instead of /sdcard when this option is used, leaving your NC unbootable. Format your SD card in your PC or another device if you need to! - fixed in 0.6.8!
FIRST BOOT TIPS -
On first boot, Launcher and SoftKeys will fight for control of the home intent - that is, when you boot the first time, your NC will ask you to pick your home activity.
*CHOOSE LAUNCHER* at first (DO NOT select 'always use this action'), and let the system boot and stabilize (3-4 minutes).
Hit Home (the N button). You'll be asked to choose your activity again, this time choose SoftKeys.
Try using one of the SU-required buttons (back or menu), and after a few moments SuperUser will prompt you to accept the action.
SoftKeys 3.06+ now prompt for SU permission at startup, just accept the superuser prompt when it pops, you'll still want to let the system stabilize for a minute or two.
If SoftKeys fails to ask for SU permissions, "Unable to execute as root":
Go to Settings -> Applications -> Manage Applications -> 'All'
Select SoftKeys from the list
'Force close' Softkeys if it's running, then 'Clear defaults'
Hit the N button, choose SoftKeys when prompted to choose your home action, accept the SU prompt when it pops.
Workarounds for some known bugs/issues:
(default in 0.5.8+) Improved Refresh-rate (no flicker! thanks [mbm]!): this should set the refresh rate to 68hz, the supposed default for the Nook Color's LCD panel -
Code:
adb shell echo 68000,1024/70/200/40,600/10/11/10 > /sys/devices/omapdss/display0/timings
Browser: force closes when opening a website that tries to use location services, due to the missing GPS. Try browsing to a url by typing in the google search box, and if you can get into the browser menu changing your homepage away from google will stop it from FC'ing on open.
Lockscreen wrong size: Simply reboot to correct this.
Touchscreen is slow/unresponsive:
Turn your screen off and then back on.
Disable Haptic Feedback in Settings -> Sounds.
Also, see this page for a possible calibration fix: http://nookdevs.com/Recalibrate_the_NookColor_touch_screen
(fixed in 0.5.6 w/included SoftKeys 3.00) No buttons! Try: http://forum.xda-developers.com/showthread.php?t=860153
(fixed in 0.5.6) SoftKeys - in 0.5.1 softkeys' buttons do not work due to a permissions issue. To fix, do:
Code:
adb shell mount -o remount,rw /dev/block/mmcblk1p2 /system
adb shell chmod 0755 /system/bin/input
Please post issues/workarounds/bugs in this thread, I'll try to keep this list updated.
To answer from the other thread...
Timeframe-- well, this isn't me doing this. But I think the devs just want to take the edges off, so be patient... I'm just the messenger on the news that it's been done. This is other people's accomplishment.
In fact, froyo was done weeks ago, though not entirely from open-source/freely distributed components like this (as far as I know).
To answer some questions--
BT not working, FM not working, accellerometer not working. Softkeys should work... dont' see why not anyway. It's stock froyo. No gapps, no Superuser.apk, no nothing over and above AOSP. Overclocking not in but should be possible... video playback hasn't been tried (it's early still!).... battery life who knows I haven't even had a chance to let it run down... I posted because the news was "out" anyway. I also can't compare to stock because I've never run stock, believe it or not. But it's based on the same kernel 2.6.29. It boots off a SD partitioned for system, data, cache, and sdcard. Only thing (I think) it touches on the internal storage is resetting that boot counter, otherwise you'd only get 7 boots at a time. Doesn't need much space. 2GB should be enough. That's what phones have anyway. Guess it depends what you want to do with it. Performance is decent, not steller compared to my g2 at least. Will benefit from OC.

@fattire
Questions on everyone's (well, mine at least) mind... please answer as much as you can, and a big big thank you!!!
1. Is BT working?
2. Is FM working?
3. Can we still use SoftKeys for hardware key emulation?
4. Can we overclock the processor?
5. How's the video playback?
6. How's the battery life compared to stock?
7. Since you're booting from SD, does that mean the internal memory of the NC remains untouched, should we need to boot stock?
and
8. How does the device feel overall?

Nice stuff guys keep up the stellar work
Sent from my LogicPD Zoom2 using XDA App
So awesome, looking forward to the progression of this!
I got my SD to boot tonight!
It defiantly isn't for the faint of heart but it seems to work well enough as a good base to start on. Pretty snappy to boot.
I would like to emphasize that this is VERY rough around the edges and if you aren't planning on hacking with the kernel, or code, or attempting to make your own rom then this is NOT for you.

Defiantly awesome work (and pure AOSP + TI drivers) which means no propritary B&N bits
Thanks for releasing such and early build to the public. It's not often you see that.
(I won't even consider playing with this build)
As a humble Analysts I grovel at the feet of your magnificent tech prowess.
(thanks)
Does this include a working JIT or is that one of the things in progress?
That seems to be one of the more compelling things from froyo (at least for a device with more internal storage than a nexus one). I would expect (well, hope anyway) that the froyo JIT would have a noticeable impact on the speed...
Mods, can we please stickie this?
Very awesome... Will try it out later today!
Since this runs off the sdcard can you power down the NC and remove the sdcard and boot normally?

You also have the option of converting the volume buttons to back/menu as well. It is documented in this thread, but the filenames have changed in this build. You will need to modify the following files..
/system/usr/keylayout/qwerty.kl
/system/usr/keylayout/twl4030-keypad.kl
I am not a developer.
I am not likely to become one at this stage of the game...
I am, however, either brave or stupid because I am downloading the image and will see if it will boot on my NC.
I do this because:
A) I want to SEE froyo running on my NC, and
2) If I have any problems, feedback might help the devs
I love seeing all the progress that has been made on these things.
Is flash supported in the browser with this initial froyo build?

I tested flash and it does work.. The flash plugin is not included in the build however, I had to find it and install it via ADB.
Just rebooted back to my regular rooted NC system after pulling the sdcard and can only say-
Marvelous.
Yes, it is slow, no keyboard and all of the other things that were spoken of in the initial posts, but IT WORKS.
I don't have time to do much else with it right at the moment, but I will mess with it more later.

Could you post the flash plugin you used? I would really appreciate it. Could you also comment on the quality of flash videos online. I'd like to watch espn3 on the nook...in bed...lol
OK, so I booted the rom, and followed the instructions at nookdevs...
Installing superuser.apk and pushing su seemed to work just fine!!!
Softkeys installed and got superuser permissions and works as well.
Installed astro file manager, and that works fine too...
At that point, I wanted to mount the usb storage and move over a bunch of APK files... mounted the nook and could only see the mlo, img file etc... no problem creating an apk folder and putting files in there, but then I can't see that folder when I look for it in astro....
Any info on simply copying files via USB using this build?
Also, thanks to all the devs for the awesome work... looking forward to playing around with this more!!!

Unleash your X2 with V6_SuperCharger

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.
Credit goes to Zeppelinrox, see this thread for more info on this script.
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.
Credit goes to Zeppelinrox, see this thread for more info on this script.
These steps were posted a while ago on droidforums.net... you might run through the comments on that forum if you have any trouble and don't want to wait for a reply.

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"

Sorry guys this no longer works...
Ubuntu removed alot of the files needed to run it on a phone off of their website which is why you are getting the errors on the script to try and install it.
Recapped:
Here's what I mean the website the script is going to to get the files no longer exists...
Heres an example to see for yourself: http://ports.ubuntu.com/ubuntu-ports/pool/universe/t/tightvnc/tightvncserver_1.3.9-4_armel.deb
I will try and find a new link to plug in but for now it DOES NOT WORK!

-Disclaimer-
This has been tested on my phone and runs perfectly fine, I am not responsible for you breaking, bricking, or dropping your phone on the floor and causing the USB cable to fall out and blow up your device.
Pre Requirements:
A rooted HTC EVO 3D or Sensation 4G
A S-off'd HTC EVO 3D or Sensation 4G
netarchy's kernel (Silverneedle Test5)
Android SDK
The USB drivers for your phone. (x32) (x64)
A microSD Card
2.3 GB Free of space on your microSD card
Know how to read to directions
Click to expand...
Click to collapse
The intense Procedure:
1. Download this version of Ubuntu. [Download #1] [Download #2]
2. Unzip the Ubuntu folder to your desktop and if you want, delete the compressed one you downloaded.
3. On your phone go to Settings > Applications > Development and turn on USB debugging.
4. Plug in your USB cable (from your computer to your phone) and mount your (mirco)SD card.
5. Move or copy over the unzipped / normal Ubuntu folder. This will take a long time unless you have a class10 microSD card.
6. After moving / copying that file over, tell your phone to unmount the (micro)SD card / Set the phone to Charge Only mode.
7. Now on your computer, go to where you have Android SDK installed. (Example on my computer: E:\Program Files (X86)\Android\android-sdk )
8. When in the main SDK folder, hold shift and right click a blank area and then click on "open command window here". It should of opened the command line window with the directory of your SDK already put in. If not type cd "C:\Your directory or location of your SDK"
9. Now type "cd platform-tools"
9.5. (Optional) "type adb devices" and check if the computer recognizes your phone. If not you need to reinstall your drivers from the download link above in the requirements.
10. Type "adb shell"
11. Type "su" so we have superuser permissions
12. Type "cd /sdcard" so the directory is changed to the (micro)SD card
13. Type "cd ubuntu" so the directory is changed to the Ubuntu File
14. Type "sh ubuntu.sh" so we can install Ubuntu
15. Type "bootubuntu" to start up Ubuntu. Next time you enter Ubuntu, you just need to type "bootubuntu" from your /sdcard/ubuntu directory, there is no need to run ubuntu.sh again.
16. If you got "[email protected]" in the command line, you have sucessfully installed Ubuntu. If not make sure you installed netarchy's kernel. If it still does not install correctly please try a different ROM, I have only tested this on SteelROM 1.1. *AFTER INSTALLING ANY ROM, YOU NEED TO REINTALL THE KERNEL.*
17. Now type "apt-get update" to update Ubuntu to the latest version. Then "apt-get upgrade" to apply the update.
18. Type "apt-get install tightvncserver" to install the vncserver. (Your telling your phone to read off it self pretty much.)
19. Type "export USER=root" To make yourself a user / the user
20. Type "vncserver -geometry 1024×800" to set the screen resolution you want to display on your phone. Remember you can always zoom in by pinching, so you don't need to make this that much smaller. You should also get prompted to set a password, do so. You will need to remember this password to log in.
21. Download the AndroidVNC Viewer off the Market here.
22. Open the viewer, and put in a nickname, your PASSWORD FROM ABOVE, and for the IP Address put: 127.0.0.1 for the port put 5901. THEN SCROLL DOWN and make the COLOR FORMAT 24-bit colors (4bpp).
And finally, hit Connect to launch Ubuntu on your phone!
For Mac users:
Finder -> Applications -> Utilities (folder) -> Terminal
When you cd to where your adb is located, cd is lowercase as are most all unix commands.
If you're unsure where to go, get to adb in your Finder, right-click, get info, the pop-up will show you the path. Note in unix that the folders (subdirectories) are separated by / and not by \ like in Windows.
Once you're there, the only trick you need to know is to tell unix that adb is located where you are, so you change the adb shell command like this:
./adb shell
That's about it, all other instructions once you're inside the phone shell are the same.
OBTW - after the unzip of the initial file from the OP, just drag and drop the whole ubuntu folder to your NO NAME drive (normal sd card formatting doesn't get a name at the factory, so by now you know that your sd card mounts like that anyways I'd suppose - just put it here in case).

I posted a different script a few pages back that I think will help you guys. I modified it so we should have no trouble with apps in sd.. I finally got a bigger sdcard so I can test this stuff and this script works great. Please guys try this script. If you download it in phone it will change the name and add a bin on it I think, so rename it accordingly and make sure it gets into /system/bin with the right permissions (755 or rwxr-xr-x), then run it

FAQS
FAQS
Do I need to have everything in the android-sdk downloaded and installed?
No, you just need to have the base sdk.
When I tell the command prompt to adb devices, my phone does not show up!!
Make sure you have installed the proper drivers for your phone and for your correct operating system
I'm not getting "[email protected]" when I type / copy-&-paste "bootubuntu"
Well, this could be for a various amount of reasons, first make sure you have a rooted HTC EVO 3D/Sensation. And by root, I mean a full root, not just a temp root or S-off. If you still do not get "[email protected]", flash your device (or go though your data folder and delete all the ubuntu files, then delete the ubuntu file off of your sd card and clear your caches.), and retry the above steps. If the problem still persists, then please PM me with your exact problem.
I'm having issues within the VNC, and I get an error message when I hit "connect".
Make sure you typed your password correctly, the passwords are case sensitive. If you still cannot get in, make sure your IP Adress is set to "127.0.0.1" and your Port(s) are "5901".
The colors on my screen look all weird and disorientated, how do I fix this?
Close Ubuntu, and re-open the VNC application, then scroll down to "Color Format" and tap on "24-bit color (4 bpp)".
The on-screen keyboard does not work and I get a different letter or character for whatever character I type!
The on-screen keyboard will work now, if you install LXDE.
I'm not good with reading text! I need a video demonstration!
For a video head here: http://www.youtube.com/watch?v=YbunTRzEQCI
How do I close Ubuntu?
Two options here:
1.Logout of the server and go to your homescreen and push menu, then go to settings, then Applications, then Running Services and close any remaining open part of the server program. The service may re-open later, do not close it though. It won't use up a noticable amount of RAM, just enough to make sure the application opens quick again.
2. Logout of the server and use your favorite task killer to close the server process. The service may re-open later, do not close it though. It won't use up a noticable amount of RAM, just enough to make sure the application opens quick again.
FAQS should be in order chronologically (until the end of them).​
I would like to give a huge thanks to EarlyMon, for helping out lost members. This thread would not be as peaceful if it were not for him.
And it seems I have forgotten to list another VERY helpful person here, danaff37. I am really grateful to both of these two for all of the help and work they have done to aid others.
Am I missing a question that you are pretty sure is asked ALOT (lol)? Then PM me please and I'll get it up here ASAP!
Upcoming Change log for final release:

Made a launchable .exe for easier updating and installing of Ubuntu
Default mode LXDE for fixed keyboard
Pushes Server application to your phone
Fixed a few problems that caused people to have an error in installing
Server application updated

Using the stock apps to sd like under manage applications (like the same as is available on a non rooted phone). The script for ch rooting can be made to work around it though. But most aren't.

[UPDATE FOR JB.15][Custom Build Prop] Increase Performance & Battery Life of PRIME

[UPDATE FOR JB.15][Custom Build Prop] Increase Performance & Battery Life of PRIME
MAJOR UPDATE: U.S. & WW. MODDED BUILD.PROP FOR NEW. 15 JELLYBEAN RELEASE ADDED. here are edited build.prop files for both the US & WW 10.4.2.15 Jelly Bean. Tweaks are listed as to what they are within the build.prop and to install just copy over using Root Explorer or similar app and then ensure permissions are set correctly. MUCH LOVE AND THANKX GO TO MR.WOOKIE FOR THIS and his constant contributions to making the prime a better device to own. I know I haven't been around as much as I don't own a prime anymore. But I can continue to update this thread as needed. Its very important that if issues arise, PLEASE TRY TO HELP ONE ANOTHER OUT. I can try to help out when I can. As always, make sure to set permissions correctly. JB build.prop Modding should be no different than previous versions. so most of the instructions in this OP/thread still apply. please post up how this mods are working for you on new JB firmware. if you notice any particular mod or line is causing problems with JB, please let us know. so it can be modified again. HAVE FUN...PRIME WILL ALWAYS BE HOME FOR ME
With the permission of the Original Developer, Seanzscreams, we bring a modified version of his mod for the 300 that now works on the Prime also. This is a custom modified build prop, that Brings Overall Performance & Battery life Improvements to the Transformer Prime. This will make your device feel more snappy and responsive overall. It should improve battery life. Other performance tweaks also will improve everyday use of Prime.Your device has to be on the latest U.S. .21 or U.S..28 firmware and rooted. If you on a ww version or other, you may need to tweak the build.prop to reflect your region version. Take a look inside the modded build.prop & see before you try it out. If you know how to edit it, give it a shot. just make sure to back up your original build.prop. If unsure, hit the link & ask the developer. It is possible to not be rooted and push this through ADB but being rooted makes it ALOT easier.
UPDATE: U.S. & WW .28 MODDED BUILD.PROP ADDED. EVERYTHING EXCEPT power collapse & wifi scanning added. some users reported issues that could be linked. same instructions on implementing this. MAKE SURE TO MAKE BACKUP OF YOUR ORIGINAL FILE. MIGHT BE BEST TO SEND IT TO SOMEPLACE OUTSIDE INTERNAL MEMORY OF PRIME. JUST TO BE ON THE SAFE SIDE.
*Users on region versions other than the US .21 or U.S. .28, read the tips at the end of this post before you attempt this. Putting this US version of build.prop in your device can cause issues if not properly edited to reflect your region.
*If you running Androwoki rom, no need to apply this tweak. the developer already added these tweaks to his ROM/build.prop.
-UPDATE: fellow member Mekrel made a .21 WW version of this for those who wish to try out. or you go the other route like mentioned in this post. the WW version is attached to this thread also.
Thanks to Hairdex for making a making a version for people running Team EOS Cornerstone build #9. only those on build #9 can use it.
-added De .21 version also
PLEASE READ IMPORTANT INFO & TIPS AT THE BOTTOM OF THIS POST IN CASE ANY POSSIBLE ISSUES ARISE.
Method described below is for rooted users as I don't really know how to do it the stock(not rooted) method through ADB. You can go to original thread and ask developer on how to push it through ADB method
Quote from developer, Seanzscreams:
" This is a modified build.prop to include all the latest ics tweaks
(from a build.prop standpoint)
forced 60fps
faster wifi connect and suplicant scan set at 100 (battery saver as well)
added deep sleep mode
added screen dithering
removed checkin back to base
kernel tweaked
dalvik mins and max set higher than stock
increased over-all fling velocity min and max now set
min at 8000 and max at 12000
a few nvidia specific graphics tweaks as well
. power collapse disable enabled
-and just a few i dont feel like explaining google is your friend"

DISCLAIMER: I nor the original developer take responsibility if you don't follow instructions or researched first. USE AT YOUR OWN RISK. It should be a fast n simple mod. Works great on my prime. If you run into issues, we will help you the best we can. Please read the important info & tips at the bottom of this post. It could eliminate possible issues from arising.
USE ROOT EXPLORER:
this modded build.prop, which is attached to this thread, goes in /system. Make sure to back up your original build prop or add .bak to the end of it(.bak). I sent a copy of my original file to my drop box. just an extra safety precaution... You will need to change root explorer to mount as RW. after you back up the original file, paste the new modded build prop into /system. then long click on it and press permissions. the permissions need to be exactly like the original file. which is rw-r--r-- after you properly set the permissions, change root explorer back to Read only. then power down and reboot, then profit. You can reboot twice to make sure everything sticks, if you want. If you don't notice anything initially, let it cache(kind of like letting a car warm up before you drive off) just like with roms. just start using tab so it can cache.
CLARIFICATION ON SETTING PERMISSIONS IF UNSURE. your permissions for this mod build.prop should look like this: rw-r--r--
...........Read. Write
Owner. X .......... X
Group. X
Others. X
I would suggest before even applying this, open the mod build prop up in root explorer. then just take a look at it all. Then cross reference the new tweak lines added with the links I will provide now. These links show all the build prop tweaks and what they do. This is to get a better understanding of what will be improved on your device Performance & Battery Savings wise. It won't hurt for you to become more familiar with what the different lines do and it might eliminate some questions concerning what each does.

EXAMPLES OF SOME OF THE TWEAKS SEEN IN THIS MODDED BUILD.PROP & WHAT THEY DO OR AFFECT: Thankx to TheFrankenstain & H M Judge threads for Reference
- Allows the tablet to sleep better: This setting puts your tablet into a deeper sleep when on standby
ro.ril.disable.power.collapse=1
- Allows your wifi to scan less frequently, saving more battery
wifi.supplicant_scan_interval=100
- Increase overall touch responsiveness
debug.performance.tuning=1
video.accelerate.hw=1
-Increases Scrolling responsiveness
windowsmgr.max_events_per_sec=300
- Faster Scrolling
ro.max.fling_velocity=12000
ro.min.fling_velocity=8000
-Increases quality of photo/Increases the memory cap when decoding JPEGs
ro.media.dec.jpeg.memcap=8000000
-Raises quality of JPEG images: makes JPEG Higher Quality
ro.media.enc.jpeg.quality=100
-Enable Surface dithering:Improves image quality
persist.sys.use_dithering=1
-System tweaks:
Change the Dalvik VM heap size
-dalvik.vm.heapsize=256m
-dalvik.vm.startheapsize = 8м
-makes apps load faster and frees more ram.
dalvik.vm.dexopt-flags=m=y
-Use Jit (Dalvik just-in-time compiler): faster better caching system
dalvik.vm.execution-mode=int:jit
-Disable error checking (Should speed things up a bit)
ro.kernel.android.checkjni=0
ro.kernel.checkjni=0
this has been running great for me so far. battery life seems improved and the responsiveness of the touch screen is unbelievable. it scrolls so fast n fluid it crazy. this is with the regular UI & within browsers. It also increases quality of your JPEG pictures. Im really impressed with it so far.
Do note though, once OTA update comes, it will knock all this out and a new custom build prop will have to be made. this is even if you accept the new OTA.
I will keep this thread updated to stay current with the developers original thread. As new updates come out, he will be modifying the newer build props within the update. So I will add those here as they come.
Make sure to click on the developer, Seanzscreams, original thread(http://forum.xda-developers.com/showthread.php?t=1641219) and give him thanks. You can leave feedback in this thread and original thread, if you wish. Feedback is encouraged as it will lead to better future results on this mod.
THANKS TO: Seanzscreams for Modding my Prime build prop. Now we have this MOD available to all prime owners on latest .21 firmware and rooted.
Attached to this post is a zip file with the custom build prop inside of it. The U.S. and WW version
*IMPORTANT:
If you come across a difficulty, you can ask in this thread or even better would be to ask in the developer original thread. He would know more on possible issues that may arise.
If you run into issues or caught in a bootloop or something here is how to use adb and push back your original build.prop file: Thanks to Mekrel
in regards to being for locked/unlocked users, I posted two sets of commands. Technically three scenarios exist:
Being locked
If you're locked, you're not going to have any third party kernel installed and therefore WILL have a secure kernel and therefore not able to push files to /system. That's why you need the command that involves pushing to the /sdcard and then using su via shell to copy from the /sdcard and then to /system.
Unlocked but with a kernel installed that's still secure
As above
Unlocked but with a kernel installed that's insecure
You can push directly to /system, so you don't have to push to the /sdcard first
If you're unlocked you're going to be running a secure kernel which means you're not going to be able to run adb as root, so even with root and the /system partition mount as r/w; you're not going to be able to push to system:
Code:
adb shell
su
mount -o remount,rw -t ext4 /dev/block/mmcblk0p1 /system
exit
exit
adb push build.prop /sdcard/
adb shell
su
cp /sdcard/build.prop /system
chmod 644 /system/build.prop
rm /sdcard/build.prop
exit
exit
Unlocked and with an insecure kernel:
Code:
adb shell
su
mount -o remount,rw -t ext4 /dev/block/mmcblk0p1 /system
exit
exit
adb push build.prop /system
adb shell
su
chmod 644 /system/build.prop
exit
exit
In regards to remounting to read only once finished, you don't have to as you can simply reboot and the commands executed in ramdisk will remount every partition with the relevant flags. Or you could:
Code:
adb shell
su
mount -o remount,ro -t ext4 /dev/block/mmcblk0p1 /system
exit
exit
you should be good to go after this.
*TIPS for users that are not on US .21 but instead on a WW or other version: thnkx to Buxtahuda & Gage_Hero
- instead of editing this build.prop with your information, edit your build.prop with any missing lines from this one. That's going to cut down on error a lot, and even if you get the right characters and spacing, the build.prop can be finnicky as all hell.
- IF you edit the build.prop use the right tool which would be notepad++ (download) not the standard windows note pad. if you use the standard windows notepad you could end up with format and character issues
*CAUTION:
We had a user who was unlocked, boot to a black screen. He got his prime back running by doing a restore from recovery. For unlocked users who want to try this, make sure to do a full backup, including the original build.prop file. Unlock users could even edit their own build.prop & add the lines one by one until it breaks. You can download notepad + yes it is +(plus). then you can edit the build prop (properly with out screwing up the format) on the pc and move it to the tablet. I'm not sure if being unlocked conflicts with this mod. just make sure you on latest .21 or .28 firmware and rooted. Then follow instructions carefully. you can even click on the original developer link for assurance on how to install if unsure how to install or if you have any possible conflicting issues. It would be best to ask developer if this is safe for unlocked users also. Unlocked users should proceed with caution and make sure you will be OK using this.
update:Developer said being unlocked shouldn't matter. I'm still waiting to hear back on what if people are on a different version like WW or something.
You can feel free to Hit my Thanks also, if you want. For putting this guide together on my Prime solely. The Prime is my PC Make sure to give feedback here & to OG developer, Seanzscreamz and his OG thread http://forum.xda-developers.com/showthread.php?t=1641219 . He made this all work for our Primes when he didn't have to. Much thanks to him & other members who contributed critical info, tips, & feedback.
Thanks to Texstar & Andromorphone for editing U.S. .28 buildprop.
That is the one I am looking for so long. Thanks for sharing.

Could you please explain how to do this without root?
okay okay.. I will try it and report back

you actually dont need root
but this is way easier if you do
you could adb push /system/build.prop
or you could just paste it into root explorer replacing your existing
(back up existing or rename it to build.prop.bak just for safe keeping )
then reboot
or
when it reboots and adb comes alive you may be able to push it to /system with: adb push build.prop /system
not really much more was explained. you can click on his original thread link to get more details or ask him about it. most seem to be doing this the rooted method. I haven't seen anyone confirm doing this adb way yet.
I get an error..
"There was not enough free disk space to complete the paste operation" when I tried to paste this into /system with the original .bak there
I had to remove the original file to make room
Also, I think you better expand on what -RW, -R, -R means for people - like exactly what boxes to check and uncheck
I forgot to add:
If you don't notice anything initially, let it cache(kind of like letting a car warm up before you drive off) just like with roms. just start using tab so it can cache. it'll take to the changes.

that's strange. I still have my original file in there renamed. I never got that error. Do you still have all those modded wifi files in there also?
edit: I saw the other part you added, I gotcha

Yes I do in /bin which is in /system - suppose i should delete those.
But this implies /system looks for and checks the size of that directory and pukes if it is beyond xx size - which is kind of interesting
Also, technically speaking, aren't permissions rw-r--r-- not -RW, -R, -R
Well, I did this and it just goes to a black screen and does nothing else.
How can I get back into the system and restore the old file?

were you rooted and on .21 firmware?
did you put the modded file into /system & set its permissions to rw-r--r--? & rename the old file? so it won't be confused with 2 files try to be activated.

Not sure how to go back to the old file..
Works great! Wow I can see a big speed difference! I can't wait to see how much longer the battery lasts.. Thanks man!

you see changes that quick?? guess I will test mine more tonight.
my install went fine and reboot went fine.
I believe in this mod type as I did similar mods to my OG Droid

Surprisingly did. I didn't think I would see much of a difference that quick. As soon as it rebooted and right after the lock screen swiping was fast and opening closing apps are much quicker load times
Edit: overall loading speeds are improved quite a bit

I'm wondering if being unlocked messes with things. Did you make a backup of your original file? if so. you can try to adb push it in there. you should go to original developer thread and post this up. As I'm not exactly sure on the adb method on getting the prime to use the original file.
ill make sure to add to the OP that being unlocked may conflict with this. As this is the only difference between yours n mines.
so you rebooting and it just went to a black screen? any Asus logo or anything? can you get into recovery and reflash your rom or restore a backup?
Anyone with insight into how he get back using the old file from state he is in now?
I don't see a wifi scan interval on either the original or this build prop. That was one I changed from 30 seconds to 100 on my phone to cut down on the power used by wifi to go out and ping and search for signals.
On my phone is it wifi.supplicant_scan_interval = 30
A bit surprised this does not exist as it can be a good battery saver
I also see some telephony stuff in this prop that seems of no value as we dont have phones

it there is one actual in there. you have to look closely. its set to 100. I just looked in saw it. its like the 4th line above the additional build properties. I believe this scan is lower than in stock configuration.
I noticed the phone stuff also. he said once he updates, he has more tweaks he will add. ill update this thread with the changes also.
