If i want to go back to default, can I just delete the file created? (/system/etc/sysctl.conf)

It should've made a backup so you can delete that one and rename the backup to the original file name...

Trusted this post and didn't make a back up before applying this 'tweak'. Original file appears to be just a blank text file. At least comparing to a fresh CM7 rom

Been getting pretty low speeds on CM9 Alpha, but then I remembered to add this. 3G went from about 300/kbps to 500+/kbps, 4G from 600/kbps to 1.2/mbps, and wifi went from 3/mbps to a whopping 12+/mbps. So thanks lots!

i have found the solution. if flash is failing. find or make the sysctl.conf file and put it on your sd card. next open root explorer then bring up menu and click settings. Then scroll down to root settings and make sure both root settings are checked. Allow superuser. Now just move the sysctl.conf file to /system/etc. then reboot. I was getting 2 bars and as soon as i did this and rebooted i got 4!!! This is amazing:D

Testing it on Blazer ROM now

Edit: I've only done a couple of tests but for me there doesn't seem to be much of a difference. Maybe .2 Mbps max for 4G download speed, but mine were never high in the first place. 3G speeds didn't change at all either.
[Epic 4G Android Development] s89281b:
It will flash on cm9 a3. have not noticed any speed increase with speed test. didnt hurt my speeds either. but i also have other tweaks in build.prop so i might already be maxed out on speed.
[Epic 4G Android Development] MДЯCЦSДИT:
Mount system before flashing.
[Epic 4G Android Development] s89281b:
I did not mount system before flashing and it flashed for me. I can see the mods in /etc/sysctl.conf. so mods did go through i just not seeing any change in performance. it is most likly due to other mods(3gturbocharger). I have this mod on other roms without turbo and it made a big improvement. i will take out turbocharger and only run this when i get a chance and see if it makes a difference. I am basing this off of speed test which does fluctuate greatly without changing anything so my results can be related to other reasons(weather, sprint, not standing on head while testing) i want to be clear that even though MY testing on MY phone on MY setup isnt showing improvement, that shouldnt discourage anyone else from trying this out. Marcusant is a great dev and this has helped my phone before with different settings. I highly recomend trying for yourself.
[Epic 4G Android Development] judogti:
I flashed mine and the new file is in /system/etc, but the system doesnt seem to be using it. When I type sysctl -a|grep vm I do not see the changes.... Any ideas?

[Epic 4G Android Development] tommi_han:
Works for me but only if the permissions of the file match the other system files...fix permission in cwm if u push the file or just flash the zip file thru cwm
[Epic 4G Android Development] peryp9:
It seems that you are correct... but you need to type the following command in terminal emulator :

sysctl -a|grep net

After the command, scroll up and look for the values found. Compare them with the original file :

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

For example, I found the following values, when reading from terminal (the following values have been listed in the same order as found in terminal) :

net.ipv4.tcp_mem = 41760 55680 83520

net.ipv4.tcp_wmem = 4096 16384 110208

net.ipv4.tcp_rmem = 4096 87380 110208

See attached screenshot of the terminal for more settings...

The only explanation that I can think of (IF the file " /system/etc/sysctl.conf " is actually used by the system) is that values listed within may only be initial start-up values, and they get changed depending on your specific network connection.

What's your opinion ?

[Epic 4G Android Development] MДЯCЦSДИT:
Some kernels don't support this.
[Epic 4G Android Development] andygallo:
The sysctl.conf file, I believe, is only read in if you run a the sysctl -p command. Also, the tcp_rmem and tcp_wmem values are overwritten every time the radio is restarted. You need to set the default buffer settings with the setprop command. So to get these settings to stick, with the sysctl.conf file in place, you also need an etc/init.d script (assuming your kernal has init.d support) with the following in it...

setprop net.tcp.buffersize.default 4096,39000,187000,4096,39000,187000

sysctl -p

Make sure you chmod the script to 755. Mind you, these settings my not have much effect on WiMax, since there is a separate default buffer size for 4g. You can see this when you switch to 4g, the rmem and wmem will be different.

Ok, so I don't even know if this is possible but after flashing this my 4g speeds almost doubled. I was bored on my way home from work tonight and I ran a speed test while driving home. I had full 4g service and I got around 2.7 mps. I just ran the same speed test in my downstairs living room with 1 bar of 4g and I got just over 5 mps. I did the test 2 times to confirm and yup it works.

Dropped my phone today getting out of my car...it probably fell about 3' and landed on the back. I have a Spec hard rubber case on it and there's no visible damage. The screen and capacitive buttons still light up, but I have no picture whatsoever on the screen. Power button works, volume works, camera seems to work and it is ringing if I call it. It also wont sync with Zune, although it is charging thru the PC.

Not sure what my options are or how serious this is, but the only thing that seems to be affected is my screen not displaying a picture, which is just terrible :mad:

Do I try and take it into Tmobile to see if they can fix, or just to fix it myself, or send to HTC? I do not have insurance on it.

Download the latest GingerReal and put it on your SD-card.

3.Wipe Data/Factory Reset.

4.Wipe Dalvik Cache.

5. Choose for "install zip from SD" then "choose zip from sd".

6. Apply the GingerReal-X.X-XXXX.zip.

7. Wait till it is done and reboot your device.
