I must be missing something. Nothing i'm doing in the folder in init.d sticks after reboot on ICS. I didn't think this was just me either as for the supercharger mod you have to have a modded version of your services.jar for it to stick (in which it didn't work for me).

I tried this Mod you have posted on CM9 by Mazda. I apply it and see in System Tuner that it took. Then I reboot, and it goes back to default. I've also tried to change my own setting in init.d on MIUI ICS and it doesn't stick either. The only way i can get things to apply on boot is if I have the app apply it on boot.

Last (bottom) 4 are my control "before"

I'll be taking it off, but thanks for sharing with us. I'm glad it has worked for some.

I uploaded these from my phone last night, so I may have messed something up for now just either do it manually, or copy the filly from the .zip to /system/etc, I'll try to fix them today, but I don't know if I'll be able to on my work computer, but if not I'll do it when I get home...

I'm researching the issue now, I will figure out a way to make it work for you...

After applying, not liking the results and removing the tweaks my tests are still in the toilet.

Your screeny won't even load. I guess I'll try the flashable zip. If not I'm gonna reflash the rom

Hmm it loads on my phone and well I did 3 test for 3g before flashing the .zip and I was getting 850kbps,1100kbps and 753kbp ..after flashing the zip ... it went all the way to 2000kbp ,1859kbp and 2050kbps .. I was really amaze ..:)

Thanks

I think you have to be on a computer browser to see it, you could try changing your browsers agent... About the fix, i've been seeing mixed results, so if you happen to be one that gets the benefits, well lucky you... If not, there is a undo .zip as well. You don't have to reflash your rom if you can't get it to work tho, just flash the undo .zip...

Same here. I'm on shooter sense 3. Amon ra 3.11 recovery. Toggled signature. Nothing.

Hypothetically this should work across the board as all android is based on linux, but I have not tested on Sense, and I'm not exactly sure if the .zips are designed to flash to the right location on a sense rom.

I also noticed a considerable jump in speed with all data modules (3g/4g/wifi). Did you flash the .zip from today, or yesterday? I'm just wondering because if yesterday, then it is the one with the

Code:
vm.overcommit_memory = 1
vm.panic_on_oom = 0
vm.oom_kill_allocating_task = 0
vm.dirty_background_ratio = 90
vm.dirty_background_bytes = 0

as well as the net speed tweak, this added tweak is a very slight memory adjustment, and honestly should be fairly unnoticeable.

I'll try a manual tweak, as per your directions. Will post results.

How do I know if the zip worked caused systcly. Conf looks the same..

sent from my reloaded evo

What do you mean it looks the same? By default this file will be 0kb and be completely blank of data, so if it's not 0kb, then changes have been made, if you have one that you have already modified, I would suggest manually entering the changes...

I know it doesn't make sense, but even after removing it and wiping caches/rebooting the speeds were still in the dump. Even after a nand restore. I'm hoping completely wiping everything and starting fresh will help.

    This is a known Linux speed tweak, and i found it on the epic 4g thread (my son has one, and I loaded CM9 on his phone) that was started by marcusant. So, i'm really just sharing the info with the Evo community, but I truly think it is quite valuable info, and will likely work on any Android based device since as stated earlier it is a Linux tweak. This has only been tested on ICS, and GB, but I'm pretty sure results will be the same with Sense...


    This is what i did, and for those of you that want to add it yourself, just add this code...

    Code:
    net.ipv4.tcp_ecn=0
    net.ipv4.route.flush = 1
    net.ipv4.tcp_rfc1337 = 1
    net.ipv4.ip_no_pmtu_disc = 0
    net.ipv4.tcp_sack = 1
    net.ipv4.tcp_fack = 1
    net.ipv4.tcp_window_scaling = 1
    net.ipv4.tcp_timestamps = 1
    net.ipv4.tcp_rmem = 4096 39000 187000
    net.ipv4.tcp_wmem = 4096 39000 187000
    net.ipv4.tcp_mem = 187000 187000 187000
    net.ipv4.tcp_no_metrics_save = 1
    net.ipv4.tcp_moderate_rcvbuf = 1
    to a file sysctl.conf (you can use root explorer to make a new file, or whatever file manager tool you like) then using root explorer copy the file and navigate to /system/etc/ mount as r/w and rename the original sysctl.conf file to sysctl.conf.bak, then paste the one you originally copied (you can add the lines of code to the original file if you are using a edited one already). Then change ownership to root/root, and permissions to rw/r/r, then mount back to r/o, and exit root explorer, and reboot. If it works you should notice your browser opening pages faster, the market much faster, and of course speed test will be faster.

    I was pm'd this as a way to get this properly working on ICS. Thanks ratkiley

    You can ignore my previous email because I found the solution. I am sharing it with you so you could update your original forum post with the missing information.

    At first, I was not able to install the data speed tweak zip files through my ClockWorkMod recovery ROM on my Ice Cream Sandwich / Android 4.0 phone. After various experimentation, I figured out the solution.

    To install the zip from the SD card,

    1. Copy the zip file into the root of your SD card
    2. Boot into Clockwork mod recovery rom on your phone.
    3. Mount the /system/ folder. (So you don't flash the files into the Recovery ROM's /system/ folder instead of your android ROM's system folder. Otherwise, you won't see the /system/etc/sysctl.conf file appear in the file system after installing the zip file.)
    4. Choose "install zip from sd card" -> "choose zip from sd card", then find the zip file.

    * The /system/etc folder does not exist on the clockwork mod ROM's file system, but it does on other android ROMs. ADB shell exposes the clockwork mod /system/ folder to you unless you first mount the /system folder. So apparently, "Mount /system" means mount your phone's Android ROM's /system folder in the running Clockwork Mod unix file system.

    This is highly unlikely, but if this somehow breaks your device I am in no way responsible... Just had to put that out there...

    For ICS users you might need to use THIS method, or you can update your services.jar file HERE (compliments of Papa Smurf151 Thread).

    Flashable Zips are below...

    So just flash, how would we undo? Just make a backup of the original file?

    Thanks.

    I'll make a undo .zip, just give me a minute...

    For those on ICS I have noticed the zip doesn't always stick. I just manually created a second file and pushed it to system/etc then set permissions then rebooted. That's when I finally noticed the vast improvement in speed. Only after a reboot did I get the increased speed.
    I was one of the doubters early on because every time I tried it, it wouldn't work and my speeds never improved. After adding the text manually though its all working perfect. Also don't forget the reboot.

    Question: Why are the values in the flashable file different from what's posted in the OP?
    1
    It was working :/ but now everytime I reboot it remounts to r/w and my speed is super slow

    sent from my reloaded evo

    Go into root explorer, and mount system as r/o, then go to a terminal app, and type

    $su
    #fix_permissions

    The "$" and "#" are the prompts, so don't type those. Once it gets done either type reboot, or reboot however you wish...
