Best result on Android 4.+
Description
Hey everyone,
So, I was experiencing significant lag as we all do from time to time, and decided I was going to get to the bottom of it.
After tracing and debugging for hours, I discovered the source of 90% of Android's lag. In a word, entropy (or lack thereof).
Google's JVM, like Sun's, reads from /dev/random. For all random data. Yes, the /dev/random that uses a very limited entropy pool.
Random data is used for all kinds of stuff.. UUID generation, session keys, SSL.. when we run out of entropy, the process blocks. That manifests itself as lag. The process cannot continue until the kernel generates more high quality random data.
So, I cross-compiled rngd, and used it to feed /dev/urandom into /dev/random at 1 second intervals.
Result? I have never used an Android device this fast.
It is literally five times faster in many cases. Chrome, maps, and other heavy applications load in about 1/2 a second, and map tiles populate as fast as I can scroll. Task switching is instantaneous. You know how sometimes when you hit the home button, it takes 5-10 seconds for the home screen to repopulate? Yeah. Blocking on read of /dev/random. Problem solved. But don't take my word for it .. give it a shot!
Update!
I've built a very simple Android app that bundles the binary, and starts/stops the service (on boot if selected). I'll be adding more instrumentation, but for now, give it a shot! This APK does not modify /system in any way, so should be perfectly safe.
This is my first userspace Android app, so bear with me!
Note that this APK is actually compatible with all Android versions, and all (armel) devices. It's not at all specific to the Captivate Glide.

UPDATE: Seeder_v7 is out, as suggested by pepoluan, it now detects for qrngd (built in rngd for Qualcomm Snapdragon-based devices), if it is there, then it will not start as rngd may conflict with it...the rngd binary is also using the latest version (it is turned off when screen is off)...users of previous versions can just flash it over...
INSTALLING
You need init.d support for this!
Download and flash:
http://www.androidfilehost.com/?fid=9390248398092764755
Here is a mirror... http://d-h.st/REX
How to use this script?:
After flashing, launch terminal emulator and type
Code:
su
seeder
You will get a menu like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
NOTE: There will be NO app after flashing! This only installs the necessary binaries and scripts...
For those who cannot install via recovery:
You get a status 0 error -> replace the update-binary in Seeder_v6.zip with one from another zip that works with your device
OR
Use the new installation method!
Instructions:
1. Download Seeder_v7_non-CWM.zip from here:
http://www.androidfilehost.com/?fid=9390248398092764756
2. Extract the zip, you will get a folder named "install"
3. Place the folder in the root of your sdcard (/sdcard)
4. Launch terminal emulator, type:
Code:
su
cd /sdcard/install
sh install.sh
5. Ignore any error messages (those are only warnings, only happens to current users)
6. You are done! The script will auto-delete the "install" folder as it is not required anymore...
Sample output:
UNINSTALLING:
And now for the way to clean up Seeder_7:
Via recovery:
Flash Seeder_v6&7_Uninstall.zip:
http://www.androidfilehost.com/?fid=9390248398092764753
Via terminal:
1. Download Seeder_v6&7_Uninstall_non-CWM.zip:
http://www.androidfilehost.com/?fid=9390248398092764145
2. Extract it to the root of your sdcard (/sdcard), you should get a file named uninstall.sh
3. Launch terminal emulator and type this:
Code:
su
cd /sdcard
sh uninstall.sh
4. You are done! Everything gets cleaned up, including uninstall.sh...

Flash now works, you can now type in terminal to turn off/on and also easier remove. Up to u if ud like to try. Note" it may drain battery more" so please do not be going all against tweak. Thanks
FLASH THIS ON GINGERBREAD!?!?!(v1.4.0)
Thanks to Zen Arcade for making a flash for Gingerbread! His Post Here!
I took a look at the original CWM package and made the following changes:
1 - swapped in our update-binary
2 - changed the mount command in edify script (not really needed since system is already mounted in gb voodoo CWM recovery)
3 - removed all mount commands from init.d script (not required since you have to have /system mounted just to read the script)
Here's a link to the CWM flashable: http://d-h.st/Kaq
I'm running this on both my Infuses - no problems noted. At work now so will not have a chance to try with games for a couple more hours at least. Only down side I can note is that the rngd binary is about 1MB in size - a small sacrifice if it does eliminate lag events
Note that this package is for GB, but should work fine for 4.x roms as long as /system is mounted as part of recovery startup. Can someone test on a 4.x (CWM9/10) rom by flashing the zip and then checking /system/etc/init.d for a file named 91RNGD or /system/xbin for rngd? I've already tested on GB and it works fine there.
Thanks bradman for posting this - all credit and thanks to the original devs who posted this.

Sorry if this is a n00b question, but if you just install the .apk do you still need to change the permissions or does it take care of it for you?

Is best to just fix Perm to brr safe, easiest way to do so if you just install the app is to go to recovery/advanced/fix permissions and reboot

I stumbled upon this myself a few days ago and have been looking into it... I can easily implement it into my source builds, but want to see how it reacts first before doing so. And btw bradman... CM10.1 is smooth as **** with nothing needed... but if this makes it even better, then thats good to hear.

Anyone tried this on 2.3.6?

im aware its smooth good job! i was just testing it on infuse and i currently had ur rom so i just gave it a try to confirm it working on infuse

that is what i am doing now! im on saurom jvu atm thanks for the quick reply ill let you know how it turns out
EDIT: i hope it works so my online game will run smoothly!

I must say, this relatively minor tweak provides a noticeable boost. I'm currently using Liquid Smooth RC9.11 with no further tweaks. After applying this tweak I've noticed faster loading times for a couple games, Google maps is much more responsive to massive view changes, web browsing is snappier, and as stated above almost no redraw delay when returning to the launcher after running a large app (like a game). I must say this under-powered and under-RAMmed little Infuse just keeps getting better and better thanks to all the work the devs here. Keep up the good work!

just flash it will do permission

Working CWM Flashable for Infuse GB
I took a look at the original CWM package and made the following changes:
1 - swapped in our update-binary
2 - changed the mount command in edify script (not really needed since system is already mounted in gb voodoo CWM recovery)
3 - removed all mount commands from init.d script (not required since you have to have /system mounted just to read the script)
Here's a link to the CWM flashable: http://d-h.st/Kaq
I'm running this on both my Infuses - no problems noted. At work now so will not have a chance to try with games for a couple more hours at least. Only down side I can note is that the rngd binary is about 1MB in size - a small sacrifice if it does eliminate lag events
Note that this package is for GB, but should work fine for 4.x roms as long as /system is mounted as part of recovery startup. Can someone test on a 4.x (CWM9/10) rom by flashing the zip and then checking /system/etc/init.d for a file named 91RNGD or /system/xbin for rngd? I've already tested on GB and it works fine there.
Thanks bradman for posting this - all credit and thanks to the original devs who posted this.
UPDATE - 2012/01/03
I've confirmed the documented improvement in speed at which Maps re-tiles the map display when making big location changes. Still testing other apps. Some games appear a big less laggy, although some disruptive lag events still occur (I suspect due to file system i/o scheduler delays rather than from lack of random/entropy data as addressed with this enhancement). I'll do some benchmarking over the weekend and report back with results.

I currently cant test this but if it turns out to work ill put it on OP. i did hear from someone that the biggest difference on GB but i cant say that for y self because i have not tried yet

I gotta say, it's very smooth so far.

Works fine on Scott's CM10. PS shows the rngd process running. Thanks

Heyyy Scott, check out this guys find

I really dunno if the tweak makes that big of an effect but I did discover a nice trick to have a nice fat entropy_avail with zero overhead.
One of the first pages I skimmed was http://linux.die.net/man/4/random which mentioned at the bottom these other files:
read_wakeup_threshold contains the number of bits of entropy required for waking up processes that sleep waiting for entropy from /dev/random.
write_wakeup_threshold contains the number of bits of entropy below which we wake up processes that do a select() or poll() for write access to /dev/random.
Normally, read_wakeup_threshold is 64 and write_wakeup_threshold is 128
I also wondered why most users report that their entropy_avail was by default in the 200ish range while mine was always by default over 300.
I had also found this page at linuxinsight. I had used that site alot when researching Kick Ass Kernelizer's sysctl tweaks.
So I thought, hey I wonder if I can use sysctl to set good values and low and behold, I looked in my script and I already have settings for both lol:
Code:
busybox sysctl -e -w kernel.random.read_wakeup_threshold=128;
busybox sysctl -e -w kernel.random.write_wakeup_threshold=256;
As you can see, I had doubled the default values - and that's why my entropy_avail was always over 300.
So I decided to mess with sysctl a bit.
Connected the phone to the laptop.
In one command prompt I watched the entropy_avail with this one liner:
Code:
while :; do cat /proc/sys/kernel/random/entropy_avail; sleep 1;done
In a second command prompt I did the sysctl thing...
I found that write_wakeup_threshold didn't effect entropy_avail at all.
But read_wakeup_threshold is a totally different story
I did
Code:
busybox sysctl -w kernel.random.read_wakeup_threshold=2048
The entropy_avail just started climbing....
All the way up to 3600+ and just stayed there. Never went down at all.
Actually, the more I did stuff with the phone, the faster the level would climb.
So it would never go down and would never get used.
I thought well maybe I should lower it so it does get used.
I kept lowering read_wakeup_threshold until it got down to 1200 and finally entropy_avail dropped to 2400+ and kept climbing until 3600 and then would drop to 2400 immediately and up again and so on...
I played with different values.
Setting it to 1000... entropy would go up to 3000 and then drop to 2000 and up to 3000 again....
Setting to 750.... entropy would go up to 2250 and drop to 1500 and up to 2250 again...
So the pattern is:
max entropy_avail=read_wakeup_threshold * 3
min. entropy_avail=read_wakeup_threshold * 2 (ie. read_wakeup_threshold * 3 - read_wakeup_threshold)
So it builds up 3 times the read_wakeup_threshold and then when it hits that limit, it drops the value of read_wakeup_threshold.
If you want to lock it it at the highest possible value (4096), you'd do:
Code:
echo 1366 > /proc/sys/kernel/random/read_wakeup_threshold
Or
Code:
busybox sysctl -w kernel.random.read_wakeup_threshold=1366
You can add either of those to any init.d script.
However, on my device, it won't go over 3600 so you can test for yourself how high yours will go.
If all you can get is 3600ish just go with 1200 (ie. 3600/3)
In Kick Ass Kernelizer I'm gonna make it like so:
Code:
busybox sysctl -e -w kernel.random.read_wakeup_threshold=1024;
busybox sysctl -e -w kernel.random.write_wakeup_threshold=2048;
That will make it bounce between 3072 max and 2048 min.
I'm making write_wakeup_threshold twice the amount of read_wakeup_threshold simply because that's what it is by default.
But hey, maybe I can save battery life if I make it 1280 just so it stays locked in at 3600+ and it doesn't have to keep rebuilding entropy_avail lol
So conclusion is: since there is a definite pattern on how entropy was being built up to a pre-determined level and dropped to a pre-determined level, it wasn't actually being used. That's just how it's programmed.
If the setting isn't there to "hold" all the entropy, it just drops/flushes it and force feeding it entropy won't make it not spit it out
So at least I found the setting that will make it hold it in lol
Maybe somebody would like to give it a try and test to see if it actually saves battery by setting read_wakeup_threshold to 1366.

This script has 2 main uses:
1. Modify an update.zip
2. Create an update.zip
For #1 - You just extract the contents of an update.zip into the placehere folder, modify its contents, and run the script stating to create an update.zip
For #2 - So far these are the options i have in there for create the update-script
1. Copy directories
2. Copy files
3. Create Symlinks
4. Delete file
5. Delete directory
6. Flash boot image
7. Set permissions for file
8. Set permissions for directory
New Features in 2.0 :
- Set java heap size / compression level for zip
- New drag/drop mode.
>>> - If you drag a folder onto the script's icon (as in Script.bat) it will compress the contents of the folder into a zip and sign it.
>>> - If u drag a zip onto the script's icon (as in Script.bat) it will sign the zip for you.
So this script guides u as u select each option, and adds the appropriate command to the update-script file. Then u exit that sub-menu and create update.zip
Heres a video for a better explanation:
This script is a result of me constantly wanting to modify roms before i flash them & users who are unaware/lost as to creating/modifying update.zips.

Awesome Gotta try it out.

I tried using this to just push a single app into /system/app just to see if it would work, but when I try to flash from recovery I get E:Syntax error in update script
when I open my update script it reads thus:
Code:
package_extract_file("LearnPython_1.1.1.apk", "/system/app/Python.apk")
Do you know what the issue might be?

Hmm thats wierd. Can u try placing the file inside a folder withing the placehere folder? N then try it. Tell me if tht works, in meantime ill try a example, perhaps the new changes i made broke something
K i figured it out, i forgot to place a ; after the line. Try placing it and then flashing. Ill fix it.

update-script is now
Code:
package_extract_file("LearnPython_1.1.1.apk", "/system/app/Python.apk");
but I still get a syntax error
Edit: I had also tried putting it in a placeholder file, but that didn't help either, even with the added semicolon

Hmm so something seems wrong with my package_extract_file syntax
Even though ive compared it to online update-script samples. Regardless, for now use the copy directories option instead.

Retry, cuz i just did it and it works fine.
Created a folder app inside placehere folder
placed my apk inside it
Ran the script, chose option 1
Then chose option 1
Then typed DATA
Then typed app
Then typed app
Then typed 9
Then typed 2
Then flashed the update.zip
Letter Casing matters, if it says SYSTEM or DATA , do that dont do data or system.
Btw, first clear out using the script. So when u run it. type y to clear ur previous work.

K i uploaded a fixed one. No file option for now just directory. And added a push to sdcard option. I think wht u were doing was putting it inside a folder and still using the file option.

Yay, it works now. Thank you for creating this and for helping me.

Well the reason i do it on something like mediafire is cuz its not xda dependant and that its one of the few sites with no waiting time for downloads. Plus i get to monitor # of downloads, in order to know if something is in demand, hence ill work on improving that.

It works just fine for me too. I just combined Chromatic3.7 rom with httclay's theme by changing the framework.apk and the services.jar files. I also deleted some system apps as well as added a couple of my own. I also put my own bootanimation.zip on there and it works fine.

My first successfull update.zip
Ok so I have messed around with this a lot and I have successfully created a update.zip rom that runs stable. I decided to go with the Chromatic 3.7 rom based off of cm-5.0.8-DS Stable. Feel free to download this and give me your feedback. I take no credit for this rom what so ever. All of the credit goes to Chromersmith and the other devs that made this, not me! This rom is only 1mb larger than the original, about 59mb. What this rom includes:
-reverse nexus style bootanimation (added by me)
-Stock ADWLauncher.apk from cm-5.0.8-DS Stable (has the nexus style launcher, but isn't all themed up. It runs smoother because it isn't as much of a system hog. Added by me)
-apps: Mytouch Music (came with rom not added), 3D Gallery (removed Gallery for same reason), cachecleaner (great for freeing up internal memory), Wireless Tether v2.0.2 for eclair, and of course all the regular stock system apps like YouTube, etc.
And of course you can modify this and re-post your own results as well the same way I did. Isn't that the whole point of this thread?
IMPORTANT! Make sure you read the Chromatic 3.7 thread to get all of the requirements and settings correct after flashing:
http://forum.xda-developers.com/showthread.php?t=679135
I take no responsibility for anyone that breaks their phone because they don't know what their doing!
And of course enjoy:
http://www.mediafire.com/?1zzhoj32oqw

I just finished my second update.zip
Ok so I put a lot more work into this one than I did the first one. This is based off of the CM-5.0.8-DS Stable rom+gapps. I got sick of having to flash the gapps seperatly after flashing the rom, so I just added them in.
-Added the Multitasking OC Kernel and a lot of other things like a black status bar mod, and a custom ADWLauncher icon.

-Added other icons to stock apps like music and a few others that I can't remember right now lol.
-Removed the stock Cyanogenmod boot animation and replaced it with the reverse nexus style one (takes up less memory and boots faster, really fast!). Once you get it flashed and get everything set up, reboot your phone and watch how fast it boots up. Mine boots in about a 30 seconds once the boot animation comes on.
Apps included:
-3DGallery (Default Gallery, removed Gallery to save on internal space)
-CacheCleaner (Good system cache cleaner to free up that internal memory!)
-New Phone.apk added from Chromatic3.7 rom (looks very nice btw)
-Wireless Tether v2.0.2 for Eclair roms.
Requirements:
-Danger SPL or Engineering SPL:
If you do not have these or know what they are then do not flash!
-I highly recommend that you have a swap partition of at least 32mb:
If you want this rom to run smoothly, or enable compcache under spare parts app.
Instructions:
-Do Nandroid backup!!!
-I recommend a wipe if your coming from anything other than cm5.0.8-DS based rom, otherwise, just flash it, and then run fix permissions!
-Download and flash as normal:
It will say welcome to cyanogenmod 5.0.8 DS! Do not be alarmed, this is not a stock version of his rom! I did not want to take the credit away from Cyanogenmod and his team for this rom, since I am using so much of it!
-SetCpu:
Install SetCpu. Run app and select auto detect speeds. The kernel on this rom will allow you to overclock way faster than you should. I can run this stably at 614MHz max, and 245MHz min on ondemand. If you go more than this, your phone will probably lock up, and you will have to pull the battery out just to reboot.
-SpareParts:
After Flashing you must change the clock and date color under spare parts found in the settings menu. I changed everything to white because it's a black status bar, but change to whatever color you wish. Also change the Carrier PLMN label color, and the Carrier SPN label color. The only color I change under the notification settings is the Notifications ticker color. Set window animations and transition animations to fast! Check fancy input animations and launcher in memory.
-ADW settings:
Under sreen preferences set Desktop scrolling speed to 0, it's silly fast! Set Desktop overshoot to 50. Select orientation sensor and auto stretch.
Under UI settings check Hide AllApps Bg and Hide AB Bg, and this will make your launcher look much better. Uncheck scrollable widgets unless you use them. Select whatever else you want, I like to select Hide icon labels and closing dockbar as well. The only one I don't check is the tint ab.
Run Firerats Patch:
Download and run Firerats Patch. This will patch things like facebook sync, enable swap partition, and a lot of other things. Dowload and place the fr-patch133.txt file on the root of your sd card. Go to terminal emulator and type "su" and press enter. Type "sh /sdcard/fr-patch133.txt" and press enter. This will bring up a list of commands for the script, along with an example of how the script works. Everything should install correctly unless your don't have a swap partition on your sdcard then it will not install swap. Everything else should install just fine. Once it finishes type "reboot" and your all done! It will take a long time to boot as it is finishing up all of the installations. Be patient and do not interrupt it by rebooting or powering off your phone!
http://forum.xda-developers.com/attachment.php?attachmentid=348484&d=1277328643
Make sure swap or compache is working in terminal emulator. Type "su" and press enter. Type "free" and enter.
I have put a lot of work into this, so that I can use this as a daily driver rom, until a stable froyo release comes out. This rom is really fast once you get it set up correctly. I mean let's face it, we have no idea how long it will take for froyo 2.2 to be realeased. So until then, let's keep on modding!
Disclaimer: I am not responsible if you break you phone because you did not read the requirements or follow the instructions correctly!

for the market- NOT A METAMORPH FILE MUST BE PUSHED WITH ADB
**EDIT ... took market down til I can fix.
i would recommend doin a nand backup before pushing this. i pushed it 4 times to my phone. 3 of those times it worked fine. the one time it didnt work i have no idea why as i didnt do anything different.
to push this go to adb shell and type :
mount -o rm,remount -t yaffs2 /dev/block/mtdblock3 /system
now back put of shell and put the Vending.apk into the push folder. now you will type :
cd push
adb push HtcDialer.apk /system/app
....................now your done.
A majority of this theme is from papasmurfs RedDawn with a few tweaks of my own and some random icons i have ran across place to place. i cant take the credit for this other than i test each thing and make sure it functions and get it to work for a stock rom (like this one) and simply put it together.
BTW: no FC's for contacts or contact widgets on this one. thats what took so long lol.... only issue i know of is setting up speed dial. other than that, all of it works. been using it a few days now. If you run into anything let me know and i will see what i can come up with. - Leadfoot

***How to check the MD5 Hash***
Windows (and mac) users:
1. download Hashtag, a free md5 file hash check utility from here: http://beeblebrox.org/hashtab/
2. After downloading and installing, just right click on any file. On Windows, select properties and you will see a new "File Hashes" tab. On Mac select "File Hashes" (on 10.5 the "File Hashes" menu item will be found under the "More" submenu). This is will start HashTab providing more or less the same view that you see on Windows. This File Hashes window displays all the hashes for the file.
3. Check the hash to make sure it's the same big jumble of numbers and letters as the hash above. If it is not the same, the download is bad and you should redownload the file.
Linux users:
1. go into your linux terminal or shell (not the adb shell)
2. navigate to the folder that contains the rom (mine is in downloads, so you would type 'cd Downloads')
3. for my rom, type 'md5sum SouthPawV1.5Final.zip
4. the output should look as shown:
Code:
OUTPUT_ZIP$ md5sum SouthPawV1.5Final.zip
F0D9E1F279FA7B0FA8636616499CD0C8 SouthPawV2.0-Beta.zip
[email protected]:~/Desktop/kitchen/OUTPUT_ZIP$
Installation:
***for newbies, see the second post under "How to root/maximizing my rom experience"***
1. Nandroid
2. Wipe
3. Flash
4. After install see configuring a2sd for more memory on the phone and JIT/Swap configuration in 2nd post! (and possibly a faster phone if you have a class 4 or higher memory card)
Bloated apps can be re-downloaded here: http://www.mediafire.com/?7ektxbiq0h65ftr
***Radio***
Also removed the Radio.img file. If you want the file you can download it here:http://www.mediafire.com/file/u2z11ar9ga6qn3a/CSouth_Radio_Signed.zip
MD5 Hash: 9157b63be585abef5812f71691cc4899
*You do not need to be flashing this file if it's already updated because that is the one file that CAN brick your phone if it's corrupted. ALSO if you ARE downloading this file, CHECK THE MD5 hash! Instructions above. It could mean the difference between a happy updated phone and a BRICKED phone.*
***How to root and Maximizing your rom experiance***
I hold no responsibility for any actions resulting from these links and/or this post.
How to root your CS Hero. Read first post, it describes everything
http://forum.xda-developers.com/showthread.php?t=581869
***How to flash any rom***
After rooting your phone to install any rom (not just mine)
1. backup everything if you have not already done so, you will lose EVERYTHING on the phone itself, (except for everything on the memory card)
1a. download my rom or another rom (as long as it's for your phone and radio)
1b. place the rom in the root directory (or the main directory rather) of your sdcard.
2. Turn the phone off
3. While holding the home button, press the power button until you see the recovery mode menu. (I am using clockwork mod 2.5.0.1 so depending on your recovery YMMV. You should use the instructions for your specific recovery system. They are using Darch's version of AmonRA's recovery, This is covered in the first post on that link as well.)
If you are using Clockwork Mod, you can use these instructions:
4. go to wipe data/factory reset and go to yes to start the wipe.
5. scroll down to wipe cache partition, and confirm
6. scroll down to advanced and wipe dalvik cache.
7. After that, scroll down to "install zip from sdcard"
8. select choose zip from sdcard
9. select the rom file from the memory card (mine will be SouthPAW!1.5-Final) and confirm to flash it.
10. Once the flash is done, reboot the phone. It's going to take between 5 and 10 minutes to boot the first time so be patient, and don't mess with it. After you get in you are golden, and nothing else is to be done. You have made it..
***how to maximize your battery performance***
This rom comes with an overclocked kernel that automatically sets itself to maximize battery life. But there are things you can set to make the kernel do what you want
***Kernel parameters***
You don't have to use any overclocking software to set the speed of the processor with this kernel Here is the parameters:
Syntax: echo "(speed in hz)" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
Example:
echo "768000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
Click to expand...
Click to collapse
Sets the cpu to max out at 768mhz
echo "710000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
Click to expand...
Click to collapse
Sets the cpu to max out at 710mhz
Also...
If your gps quit working for some reason do this:
mount -t debugfs none /sys/kernel/debug
echo "NORMALIZED_SLEEPER" > /sys/kernel/debug/sched_features
echo "NEW_FAIR_SLEEPERS" > /sys/kernel/debug/sched_features
Click to expand...
Click to collapse
To change the cpu governors for this kernel (the built in ones) here is how:
Type this to find the available governors:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
Click to expand...
Click to collapse
The ones available are:
conservative
ondemand
userspace
powersave
performance
interactive
And then to change the governor, you type this:
echo "nameofgovernor" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
Click to expand...
Click to collapse
I haven't found full explanation on ALL the governors, but I guess it's a no brainer, however here is the info I pulled off of the kernel thread:
(For Interactive governor)
This governor is designed for latency sensitive workloads, UI interaction for
example.
Advantages:
+ significantly more responsive to ramp cpu up when required (UI interaction)
+ more consistent ramping, existing governors do their cpu load sampling in a
workqueue context, the 'interactive' governor does this in a timer context, which
gives more consistent cpu load sampling.
+ higher priority for cpu frequency increase, rt_workqueue is used for scaling
up, giving the remaining tasks the cpu performance benefit, unlike existing
governors which schedule rampup work to occur after your performance starved
tasks have completed.
Existing governors sample cpu load at a particular rate, typically
every X ms. Which can lead to under powering UI threads when the user has
interacted with an idle system until the next sample period happns.
The 'interactive' governor has a different approach. Instead of sampling the cpu
at a specified rate, the governor will scale the cpu frequency up when coming
out of idle. When the cpu comes out of idle, a timer is configured to fire
within 1-2 ticks. If the cpu is 100% busy from exiting idle to when the timer
fires then we assume the cpu is underpowered and ramp to MAX speed.
If the cpu was not 100% busy, then the governor evaluates the cpu load over the
last 'min_sample_rate' (default 50000 uS) to determine the cpu speed to ramp down
to.
There is only one tuneable for this governor:
/sys/devices/system/cpu/cpufreq/interactive/min_sample_rate:
The minimum ammount of time to spend at the current frequency before
ramping down. This is to ensure that the governor has seen enough
historic cpu load data to determine the appropriate workload.
Default is 5000 uS.

One last thing is that this kernel keeps logs. Even though they are hard to read if you want to see them, type this:

***how to partition for apps2sd for Amon Ra's Recovery and Cyanogen's Clockwork Mod Recovery***
Instruction Source: http://www.villainrom.co.uk/wiki/index.php?title=Apps2SD#Normal_Installation
How to Setup SD card partitions from AmonRa's Recovery:
1. backup your stuff on your memory card. It is very possible that this will erase everything on your memory card.
2. Shut down the phone
3. Press and hold the home button while pressing the power button. Keep holding the home button until you get to the recovery menu.
4. Select Partition sdcard
5. Select Partition SD
6. Set the following partition sizes using the trackball or volume buttons:
-ext: 512MB - recommended. You will feel like you can install everything from the market.
-swap: none -not a prerequisite but recommended. use at least 30mb.
-fat: remaining
7. Reboot the phone. It may take a little while for boot to finish on this boot only.
How to Setup SD card partitions from Clockworkmod Recovery:
***Do not partition with Clockwork mod. There are some issues that I have read that will mess up your install***
There are alternative methods for this, but it's just easier to use Amon_Ra's image for this.
***How to setup a2sd/Swap/JIT***
A2SD is already enabled by default on this rom. However Swap and dalvik to sd is not!
To get swap working (if you made a swap partition on your sd card)
1. get to adb
2. adb remount
3. adb shell
4. a2sd reswap
To move Dalvik cache to sd -
5. a2sd cachesd
VOILA! 149MB free on the phone! *w00t*
Also there is more config you could do here. You can enable JIT *dunno if it works, so add at your own risk*
***More info for a2sd configuration***
Code:
Standard Apps2SD Commands:
--------------------------------------------------
reinstall
Moves free and paid apps to the ext2/ext3/ext4 partition on your secure digital card. Removes the No A2SD flag file.
This is used if you have already executed an a2sd remove command. Otherwise, this part is automatically performed when Apps2SD is started.
File removed: /data/.noa2sd
remove
Moves free and paid apps to the internal phone storage. Creates the No A2SD flag file.
File created: /data/.noa2sd
Swap Partition Commands:
--------------------------------------------------
reswap
Removes the No Swap flag. Allows A2SD to activate the swap partition.
This is used if you have already executed an a2sd noswap command. Otherwise, this part is automatically performed when Apps2SD is started. Note: This command has no effect on roms where the swap space is not built into the kernel.
File removed: /data/.noswap
noswap
Creates the No Swap flag. Prevents A2SD from activating the swap partition. Note: This command has no effect on roms where the swap space is not built into the kernel.
File created: /data/.noswap
swappyxx
Sets the swappiness setting for the swap file. xx sets the swappiness percentage used. (i.e. to set swappiness to 30%, type a2sd swappy30.
Dalvik Cache Commands:
--------------------------------------------------
cachesd
Moves Dalvik cache files to the ext2/ext3/ext4 partition on your secure digital card. Creates Dalvik Cache to SD flag.
Caution: If your phone fails to mount the ext2/ext3/ext4 partition and your dalvik-cache is pointed to the SD card, you will likely end up in a boot loop. Execute a2sd nocache from adb shell to rectify the issue.
File created: /data/.dalvikcacahe
File removed: /data/.dcpartition
cachesdreset
Same as cachesd above, but erases the contents of the dalvik-cache after move. This performs both the a2sd cachesd and a2sd resetcache all in one command.
File removed: /data/.dcpartition
cachepart
Moves Dalvik cache files to the /cache partition in your phone. Creates Dalvik Cache to Cache Partition flag.
Caution: Some phones do not have enough space to put the dalvik-cache on the cache partition. Also, some roms that have SenseUI installed may not work well with the dalvik-cache on the cache partition (although this issue appears to be fixed starting with Darktremor 2.7.5.1). If you experience issues such as force closes, try moving the dalvik-cache to the SD card (a2sd cachesd) or internal storage (a2sd nocache) instead.
File created: /data/.dcpartition
File removed: /data/.dalvikcache
cachepartreset
Same as cachepart above, but erases the contents of the dalvik-cache after move. This performs both the a2sd cachepart and a2sd resetcache all in one command.
File removed: /data/.dalvikcache
nocache
Moves Dalvik cache files to the internal phone storage. Removes all Dalvik Cache flags.
File removed: /data/.dcpartition, /data/.dalvikcache
nocachereset
Same as nocache above, but erases the contents of the dalvik-cache after move. This performs both the a2sd nocache and a2sd resetcache all in one command.
File removed: /data/.dcpartition. /data/.dalvikcache
resetcache
Clears the dalvik cache and restarts phone.
Apps2SD Diagnostic Commands:
--------------------------------------------------
check
Performs a symlink and flag file check on your setup. Outputs a report that shows you if
there are issues with your Apps2SD setup.
repair
Performs a repair of all symlinks based on flag file activation.
diskspace
Shows disk space statistics for the ext partition.
sysinfo
Displays information about your phone, partitions, swap, and more.
Also writes a dump file that has an entire profile of your phone. This is for troubleshooting only.
File Created: /data/dtsysdump.txt
swapspace
Shows swap space statistics for all swap space active on the phone. Note: This command has no effect on roms where the swap space is not built into the kernel.
ZipAlign Commands:
--------------------------------------------------
align
Performs a one-time zipalign on all APK files in /data/app and /data/app-private.
zipalign
Allows ZipAlign to execute during the boot process. Creates the ZipAlign flag file.
File Created: /data/.zipalign
nozipalign
Prevents ZipAlign from executing during the boot process. Removes the ZipAlign flag file.
File Removed: /data/.zipalign
Dalvik Setting Commands:
--------------------------------------------------
jit
Installs DalvikVM JIT.
WARNING: Do not run this command if your phone has NAND protection active.
nojit
Removes DalvikVM JIT.
WARNING: Do not run this command if your phone has NAND protection active.
defaultheap
Resets the Dalvik heap size to the default heap size.
File Removed: /data/.smallheap, /data/.largeheap, /data/.jumboheap
heapsizexx
Sets the dalvik heap size to xx. For example, to set the dalvik cache to 24mb, type a2sd heapsize24. To reset back to default, type a2sd heapsize0 (that's a zero, not the letter "o")

***How to push an apk file using adb***
*Of course you have to have a rooted phone to do this, if not check the ***how to root*** section first before getting this far.*
This tutorial is going to use the linked deleted files zip from the link in the first post.
1. Download the Android SDK for your appropriate Operating System from here: http://developer.android.com/sdk/index.html
2. Once downloaded, be sure to download the deleted files zip from the link in the first post.
3. Extract the Android SDK file to an easily findable folder
4. Extract the deleted files from the zip file, and copy the apk file you choose to the AndroidSdk\tools folder. For reference I will be using the Dialer.apk file in this tutorial (not included in the zip).
5. connect phone to computer and select "charge only" from the menu.
(*for windows Vista/7/XP*)
*prerequisite* - you must have the adb drivers installed to do this in windows.
6. Click Start, go to > All Programs > Accessories, and from there, right click 'command' (something like that), and click 'open as administrator' (XP users do not have to do this, just go to Start > Run, type cmd, and press enter)
7 .navigate to the android tools folder you put the apk file in (the command to change directories is 'cd' and then a space, and the name of the next folder, so to navigate to the 'android' folder, you would type 'cd android', and then you can use 'dir' to see the next directories till you get to the right folder.
8. type 'adb remount'. This is going to start the adb system, and then remount the phone in root mode.
9. to check to see if your phone is mounted and everything is kosher, type 'adb devices' and it should show something on the bottom that should be your device or serial of the device. If it says ??????????? then it's not working.
10. type 'adb push HtcDialer.apk /system/app'
11. DRINK A BEER! You have pushed an apk to your phone! To check if it is installed, simply click the call button (or press phone on the rosie), go to settings and select speed dial. Then see if you can change/add a number to speed dial #2. This could possibly require a reboot to actually start the new version of the installed software but you should just be able to go ahead and use it
(*for Linux*)
6. Once you extract the android-sdk-linux_x86 folder, go to the terminal, and navigate to the android folder pretty much the same way as windows, except instead of using dir (ubuntu users can use it), use 'ls'
7. type 'sudo ./adb remount' and when asked, type the administrator password for the linux system. This is going to start the adb system, and then remount the phone in root mode.
8. To check to see if your phone is mounted, type 'sudo ./adb devices' this should show your device.
9. To do that actual push, type 'sudo ./adb push HtcDialer.apk /system/app'
10.

Hell yeah! Although the neighbors didn't appreciate me running around in the front yard naked! Hmmm.... Maybe I will try the backyard next time.

Good job. I'm glad somebody finally got a CSouth Rom on here.
If you need any assistance let me know.

Ok I go to filedropper site but all I get to download is an empty folder, 66.7kb????. Has the file name but no data, or am I completely missing the right link? Do I need to join to download? Thanks, would really like to try this ROM out.

I got the download, followed all steps, it says that the zip is bad. I deleted the old one, transferred a fresh one to card, same story. I'm downloading the zip again just to make sure it didn't corrupt while downloading.
Anyone else run into this problem?

zip flashed fine for me. Just booting up

Can this be used in other non-sprint heros?
Also, I was wondering if it is possible to have like a stripped / universal version for non-sprint heros and then install CS’s or other carrier’s stuff apart like DarchDroid did with his naked rom with Google ****s apart.
Thanks for sharing it!

I downloaded it from the link with no problem. I did the following:
1.downloaded the zip
2.transferred it to the SD Card
3.HBoot
4.Created Nandroid
5. Wiped everything
6. flashed in zip file
It works pretty good. I can't get my yahoo account to work. I also can't get the new widgets to download to the phone and work. They download and then I don't get them. Hmmmm....

Anybody know how to change pri version? Mine is 1. Something but my non rooted phone is 2.51_013

Even though I am on AT&T with a Magic and Captivate it is good to see some Cell South love around here. I will be using your rom to flash to as many friend's Heroes I know.
Bring on the Incredible, Milestone, and Galaxy S now C South!

That is odd. I have no idea tbh, but I'll try to check it out.
From here on out, any questions asked will be answered in the 2nd post on this thread.
***link is fixed!! Any issues please report!***
And yes this rom should work for non-cs users, but always take caution and do like you do with sprint roms, and it should be ok (and for those who didn't get voicemail notifications, this should support it)

To Mr. Danger, yes I will need some help soon. I want to branch this rom out to a couple of different versions. 1. With no apps (well junk apps anyways) with helix launcher and no sense, 2. With no junk apps with sense, and 3. Just the full montey (like now but with no issues)

This may be a dumb question, but you do need to root before applying this ROM, right?

Yes, the phone has to be rooted before loading anything except for the stock updates from the carriers.

I have working on a project in the form of an app, which guides you through the installation of Ubuntu within android via chroot. It includes a ubuntu 10.10 image I have been working on which includes lots of program to allow users to develop program/scripts etc within Ubuntu on there phone/tablet.
However I have I have yet to get much testing on this device and would like more feedback from users!
Please post your device/kernel/rom along with what did and didn't work, so I can draw up what I need to change in the next release of the app/ubuntu build.

12.04 images
I have now started work on building new 12.04 images these come in core (just the bear-bones ubuntu) and full (ubuntu with GUI and other programs) and will be updated as 12.04 moves through its milestones (and when I make new updates to the mods I make from the main stream arm port).
These are for testing ONLY until 12.04 reaches stable release.
You can view the images here:
http://sourceforge.net/projects/linuxonandroid/files/Ubuntu/12.04/
I also want to build up a small group of testers who I can email with new images and scripts, these will include all future distros that I do. If you are interested in joining this test group please PM me or send a email to [email protected]
The only requirement is that your willing to test and send feedback along with screen shoots etc where required, it would also be good if your willing to try different roms and kernels for your device!

Indeed its VERY odd that stock works but custom roms do not work...should really be the other way round, perhaps something to do with how the device file system in custom roms is different or something?
I don't know, this is the problem trying to support as many devices as possible, I don't have the device to test and work out what's wrong, just got to keep basically stabbing into the dark until I hit something

Change log for new release (release will be in the next few days for paid end of next week for free) - all new images etc will be added to the first post as they are finished and uploaded!
*PAID app now supports 960x540 'qHD' resolution

Yep, I was really enjoying - had PHP and mysql installed and working as a wee test environment, then flashed FM and no more Ubuntu.
Thanks for the work - appreciated

If I manually downloaded the script and the image, where do I put
the extracted content of the zip, and the script ? on the root of external SD or phone storage ?

Place them in a folder called ubuntu on either your sdcard or internal memory as you have both either should work

Thanks, by pressing ahead without knowing I put the files there, however, in terminal emulator, after aquiring superuser persmissions, changing to the ubuntu folder wont work. I must be doing something wrong. I came as far as cd /sdcard but /sdcard/ubuntu fails. Asking ls -a says dir is empty ? Linux noob

check in a file explorer where the sdcard is mounted, sometimes the internal memory is mounted as the sdcard directory and then the sdcard itself is mounted in another directory within that.
Once you work out where its mounted then just cd to that location

which Kernel/Rom?

Hi
Before run ubuntu.sh check if loop inst bussy with other kind of programs who use it.
try losetup will show you how many loop you have used and edit ubuntu.sh to get 1 free
like last 1 user will be 10 then line with busybox mknod /dev/loop11 b 7 11
and wher you see loop0 change to loop11 or any free number.
Hope will works for you.

Hi,
Nice work but you forgot something.
Your image wont work on many device since the /sdcard partition if VFAT who limit the file to 2G.
converting /sdcard to ext2 or ext4 is the way to work with files larger than 2G.

Thank you very much I will integrate these changes in the next version of the script

you can also change de fstab line where root partition is mount by uuid and replace by name

losetup returns nothing...
I also asked the dev of FM kernel and he told me that it has loop capabilities

if losetup show nothing then or you dont have loop set or you not root.
for see if you r root type id and the have to show your id. If is not root type su -
For the no loop set then the original ubuntu.sh have to work.

Runs perfectly on my Note
Had rooted it yesterday with CFRootFlasher

*/Haters gonna hate/*
ROM currently "DISCONTINUED". But, the init.rc tweak remains :fingers-crossed:
Hi to all those who are reading this! Lemme answer a few questions before I get started.
First of all, What kinda name is this???
TBH, I haven't yet thinked of a name for this... So, I just named it Stock ROM MOD
And, the name has been thought of! The name is... CyanicSense! Why this name? More details later
What does this do?
Though this is gonna be as stock as possible, the major feature that I had planned out for this is reversed-mount. As you might know, stock ROMs definitely do have mounts2sd (which might give some trouble in setting up), but, complete reversed-mount (i.e. the /sd-ext partition mounted as the /data partition as the int2ext script does, hasn't been achieved yet (on stock ROM). So, practically, this does that stuff.
How is this even possible?
Believe me. This ain’t no magic. Simple init.rc tweak… Mounting the mtdblk0p2 partition, which is basically the sd-ext partition as we better know it, in the /data folder does the trick. In CyanogenMod, this is done via the famous int2ext script…This is a more or less similar command, done during startup. Just make some changes to init.rc, and Voila!!! Your sd-ext is mounted in the /data partition.
So, why make a new thread for this???
Erm, but that ain’t the end of story here. I am planning on some more features. Current features are minimal, reversed-mount, and updated apps. Yep. Updated apps, not one but all of them. I can assure you that you will have every single update including Google Play Store v4.0.xx in this ROM. Also, applications which were basically “stub’s” have also been updated, so that you wouldn’t have to download any more apps. P.S. I have added a small file explorer, named “Explorer”, by Speed Software, the same people who brought about “Root Explorer”. Planning to replace it with OI File Manager in next build, if people prefer it
So, those were the two features of this ROM. Also, I am planning to work on some other features, which mainly include, init.d script support, and, removing bloatware. Currently, there are around 10 apps which I don’t use, and presume that most other users wouldn’t be using it either. So, I am gonna either make them uninstallable, or remove them completely, so that one can get more /system space More features might come up too. You can request new features, but… be reasonable
Is it safe???
I can’t answer that question, but, I am guessing the answer is yes. Why I think so??? Because I am using this as my daily driver for the past few days. Also, “reverse-mount” via scripts like int2ext, and mounts2sd do the same thing, so, I don’t think its gonna create problems
Will it make my phone laggy?
Not sure. Works fine in my Class 4, 8 GB memory card. Anything Class 4 and above, I assure you it wouldn’t “visibly” lag.
What about gaming?
Well, this is the part where you come in. I don’t use my phone for gaming, so, I can’t be sure whether Temple Run 2 is lagging, or its I who can’t play it properly But, one fact can be sure that Stock ROM isn’t always the best choice for gaming.
Anything else left?
Yeah… This build is… kinda heavy. 160+ MB is definitely too big for the “stock” ROM. It is because of all the updated apps which were included. I will try to make subsequent builds lighter, and more bloatware free
Now that Q&A Section is over, let’s get back to business. The simple init.rc tweak is explained in the next post.
Instructions:
Pretty basic. Wipe everything, except SD-Card, and flash the ROM.
The following video might give you a slight idea
P.S.: Recovery used: TWRP 2.5.0.0 (http://forum.xda-developers.com/showthread.php?t=2123503)
Bugs:
I need help with that If you encounter any bugs, please report immediately in this thread.

Here is the link… 162 MB approx. Why so big? You are the typical TLDR case. Read the Q&A section above.
Beta Link: http://forum.xda-developers.com/showpost.php?p=41966646&postcount=19
Any issues, please post in this thread. I will try to fix it, ASAP

init.rc tweak that I used:
First of all, get a stock boot.img, and boot_img tools from here: https://github.com/sakindia123/boot-image-tools
Unpack it to some location safe, and, copy-paste the boot.img into this folder.
Then, run the following commands:
Code:
mkdir -p unpack
Code:
./unpackbootimg -i ./boot.img -o unpack
Code:
mkdir -p boot
Code:
cd boot
Code:
gzip -dc ../unpack/boot.img-ramdisk.gz | cpio -i
Code:
cd ../
Thus, you will have the ramdisk of your boot.img in the "boot" folder. Open up that folder, and open "init.rc" with any of your favourite editor.
Now, search for this line:
Code:
mount yaffs2 [email protected] /data
Replace that line with this:
Code:
mount ext3 /dev/block/mmcblk0p2 /data nosuid nodev noatime nodiratime barrier=0 data=ordered commit=15 noauto_da_alloc nouser_xattr errors=continue
Now, I know you are confused... I too was, at first. So, let me make things clearer for you...
This is basically a mount command, which is executed in this order
mount [type of partition] [partition] [mount directory] [options]
So, the partition type is ext3, to be made more compatible with most devices.
/dev/block/mmcblk0p2 is the sd-ext partition.
/data is the folder we are going to mount the partition in.
nosuid and nodev: Allow an ordinary (i.e., non-root) user to mount the filesystem if one of his groups matches the group of the device.
noatime and nodiratime: Access timestamps are not updated when a file is read. So, there is no writing on the partition everytime the disk is read.
barrier=0
This enables/disables barriers. barrier=0 disables it, barrier=1 enables it. Write barriers enforce proper on-disk ordering of journal commits, making volatile disk write caches safe to use, at some performance penalty. The ext3 filesystem enables write barriers by default. Be sure to enable barriers unless your disks are battery-backed one way or another. Otherwise you risk filesystem corruption in case of power failure.
data=ordered
Specifies the journalling mode for file data. Metadata is always journaled.
commit=15
Sync all data and metadata every 15 seconds.
noauto_da_alloc
does give a slight performance increase, especially when working with databases..
nouser_xattr
Support "user." extended attributes (or not).
errors=continue
Define the behaviour when an error is encountered.

Nice work bro.
For I understand it, is a stock ROM with memory script by you only, yes?
Sorry my english lvl xDDD....

Good job
Edit: well.. must say brother you did good work..
Rom is purely stock with only this tiny mod..
No bugs till now

This ain't no memory script.
TBH, I haven't even enabled init.d support yet. This is solely related to boot.img's init.rc... Which initiates reverse mount when you start your phone.

Nice tut. One thing that the rom is 1.43.xx based, right?

Stock ROM, version: 1.43.720.2

Brother.. here's a big problem..
The data folder of the Rom is now empty and all the app's apk files and app data installed can't be accessed using the root explorer..
And it is no where.. o can't find them..
Did you make a link to the data folder while mounting the ext partition to data..??
Sent from noob machines

I recommend using another application.
P.s. you will find it in the data folder only. It won't be in the sd-ext folder.
P.s. sorry for the short reply. I ain't at home currently
Sent from my HTC Explorer A310e using xda app-developers app

I used solid explorer..
I got them.. but on es file explorer.. the folder is still empty..
And also there is no sd-ext folder in root... Because you didn't make one..
Sent from noob machines

Did you enable Root Explorer or so...
AFAIK, even in the latest update, root exploration should be first enabled.
Press menu key, and in tools option, there will be the "root explorer" option, or a similar option.
Enable that, and then, you will be able to browse the data partition.
P.S.: if you don't get a superuser request, it will not work.

OK got it...
Thanks brother...
I got my mistake... it works now..:good:

Need help for NextGEN, Xenon, Ateeq, and Explode, and any other sense based ROM that I missed :silly:
I need some info about these ROMs, preferably in the following format:
init.d support: yes/no
mounts2sd used?
If yes, application included or not?
Post this information along with boot.img of those ROMs
Not a stable internet, so, can't possibly download all those files.

I have this..

ORIGINAL THREAD HERE: https://forum.xda-developers.com/axon-7/development/2-15-2017-axon-7-msm-8996-cpu-vm-ram-t3557392
This mod was originally created for the Axon 7, but due to several requests, I've modified a version for the G5, please see below, and post questions or comments in the original thread above. Please state you are a G5 user if you have feedback in that thread, to consolidate user feedback and speed up response time.
Custom tuning for a device is always a necessity. "Canned" settings will get you by, but they are certainly never optimized for a specific device. In fact, Linux typically takes a general approach to find harmonic balance in default settings that will, for the most part, work in an acceptable manner for just about any device. There are a lot of resources available on this device, so we should utilize it in a manner appropriate to squeeze out as much battery life and performance as possible without sacrificing much of those outputs, don't you think? This is going to fix that for you.
Here is what is required of you before you begin:
1. Must be rooted
2. Must have the G5 OR a device running the Snapdragon 820, as this modification is not so much device specific, but hardware specific. The important aspect being the snapdragon 820 and the RAM disk size.
3. Must have write protection disabled. If the G5 requires write protection to be disabled, see the code and instruction below:
Using adb shell:
Code:
adb reboot disemmcwp
Using Linux terminal (from your phone, for example):
Code:
reboot disemmcwp
Let's begin.
Getting right to it, here's what I've done:
- modified parameters of the interactive governor, and quite extensively at that (search some of my threads if you want a little bit of a breakdown of the general approach I take)
- reconfigured input_boost parameters
- reconfigured vm parameters (again, the device has a lot of RAM resource, this will utilize it and give you a far better user experience. Basically, I've adjusted dirty_ratio, dirty_background_ratio, swappiness, and other parameters of the virtual machine.)
- disabled zRAM for 6 GB variants (RAM compression, again, not needed on this device really, this mod will save you CPU cycles and power) this will not apply to G5 users, you will still have zRAM enabled.
- remapped minfree parameters for LMK (low memory killer) again only for 6 GB variants
- Tuned CFQ scheduler for flash storage devices
- Tuned "core_ctl" module (needs kernel support, I recommend freeza's latest version of BeastMode. For those wondering, yes, you can still use this mod with the stock kernel. It won't break anything.) again this will only apply to devices that support core_ctl at the kernel.
In a nutshell, that's what we're looking at here. I can guarantee you this will have a significantly positive impact on your device. Turbo time, homies.
How to install????
Easy. First, the file we are replacing is found in /system/etc... it is the "init.qcom.post_boot.sh" file - this file is basically shell scripts, which are applied at boot via this particular shell file.
All you have to do is download the file to your device, open up a file explorer (must have root capability), navigate to the /system/etc folder with said file explorer, mount your /system as RW (read write), delete your stock "init.qcom.post_boot.sh" file, and replace it with mine.
After you've successfully done this, change the new file's permissions to rw-r--r-- (0644), and then reboot!
Or, if you are brave, you can do it manually via a terminal app and get your fingers wet... if you choose to do that, see below:
Make sure the file is located on the root of your internal sdcard in /sdcard, open your terminal app (again, must have root) and type the following commands, hitting enter after each one (be careful to pay attention to the spacing).
Code:
su
Code:
cd /
Code:
mount -o remount,rw /system
Code:
cd /system/etc
Code:
rm init.qcom.post_boot.sh
Code:
cd /sdcard
Code:
mv init.qcom.post_boot.sh /system/etc
Code:
chmod 0644 /system/etc/init.qcom.post_boot.sh

That's pretty much it, guys. Enjoy!

Question,does that matter for your results if I'm using an other governor,cause I'm currently on alucard?? Stock rom but a custom kernel (Asgard for g5 to be exact)

You will notice minimal to no difference if you are using another governor.

Any pro can do a flashable zip?

Any n00b can copy and paste

Will it work on Android 6?

I don't know it's placebo or not but after replacing the file I have now a better GPS fix and accuracy I am on the H850 so thanks on the OP

yes accurancy gps, not lag boot, very smooth. thanks!!!!!!!!!!!

Okay,last night after I've replaced the file, changed to interactive gov,0.2% lost during the night with wifi and mobile data off here is my current stats. Was a bit surprised though and I'm not sure if it's a bug in reading . But hey that's what it shows.

How to mount System as R/W? When I set permission I get error evice is busy

Worked like a charm using Fulmics Rom 2.0.
Hint for some who have issues with mounting RW: Use FX file explorer for this. Works just fine.
Will monitor and report how it works.

My Problem. I go to /system/etc and I can´t find this file. I´m on Root with FX file Manager. What am I doing wrong?
