I heard that modifying a few lines in build.prop can increase speed, os this true? What lines?
My 3g/H download speed is 22kbps, thats too slow, at first i thought it was my phone but my whole family is on the same carrier with different phones(galaxy,motorolla,iphone,bb bold9000, etc) same speed
I HATE that

Hello folks
First time android user upgrading from iphone 3gs - been researching a lot about gs2 and android info in general over the past week since i got the phone.
My question is does rooting the galaxy s2 increase my hsdpa speed? Im mainly concerned about dl speed im getting anywhere from 1mbps to max 3mpbs according to the speed test from various apps/speed test sites. I learned that some carriers (at&t) will cap your hsdpa speeds and by rooting you can obtain true/full hsdpa speed. I also ran across this article that shows a method by making some edits on your phone to increase connection speed and was wondering if it was legit. (pasting some info as i cannot post links yets):
OK Samsung Galaxy S2 owners, lovers here is nice little tweak/hack for you if happen to be on the AT&T 3G/4G network and not satisfied with your data speeds. This comes via uskr an XDA developer forum member who had trouble with the slow performance of the AT&T data networks, so he came up with this tweak. Using this tweak he managed to increase the data speed from 3 to 4 times! Although, your mileage may vary but you can give it a go, if you are experiencing slow 3G/4G speeds
Method 1:
Note that for Method 1 you need to have installed Root Explorer.
1. adb pull /system/build.prop (this is not essential but just required to make a backup copy)
2. Launch Root Explorer on the phone
3. open /system folder and click on "mount r/w" option
4. open the build.prop file on Root Explorer (to edit the file)
5. Add following code to the end of the file:
ro.ril.enable.dtm=1
ro.ril.gprsclass=12
ro.ril.enable.3g.prefix=1
ro.ril.hsdpa.category=28
ro.ril.hsupa.category=9
ro.ril.hsxpa=3
6. Save and quit Root Explorer
7. Reboot your phone and enjoy!
I honestly didn't plan on rooting but if it will help my dl speeds im def planning to do so asap. Any help/feedback would be appreciated!
No, rooting it won't increase data speeds. And given that testing by developers I trust indicates that most of those build.prop values do NOTHING on Samsung devices, I wouldn't bother with them.
I'm coming from a thunderbolt and that was my first android and rooting experience. I just wanted to make sure using cwm is the same.
If I want to flash just the kernel that's cool right?
I mainly want to get the smartass governor because that worked well on my tbolt.
Is flashing radios done in bootloader like the thunderbolt? I believe the tbolt was unique because it was the first so it had two radios. I assume the note isn't?
Sorry, that turned into more than one question.......just want to be happily flashing again.
yes, you can flash only a kernel, or only the recovery
I've had this note now for 3 weeks....am stock rooted with different da_g kernel v2 .....overclocked with set cpu. few build prop tweaks I edited..and this phone is blazing fast and not one bug....gonna keep this way to ics gets here and maybe get a rom then,as of now they seem unstable,and not worth it...stick with your kernel only idea.....
thanks for the responses.
That's exactly what I was planning to do wish.
I would like to debloat though.
I was going to flash the 0.2 kernel. Is that what you meant?

I have already taken the processor down to 192 and might oc but just a little. I'd start of with keeping it at 1.5 and see if its fast enough. I really liked smartassv2 on my Tbolt.
Thanks again.

yes that's the one 'Version 0.2 CWM Zip' And yes debloat everything you find necessary...it does help i should have been more specific sorry.
i have mine set at 384 min and 1.89 max on demand...in set cpu
From here are some build prop tweaks: http://forum.xda-developers.com/showthread.php?t=1560588
i didn't use those net speeds because are phones have that by default you can tell from looking in folder "int.rc"
And no boot animation is just wierd and still takes as long booting ..lol
in root explorer i only used parts of that script, im using
#Battery
ro.ril.disable.power.collapse=0
pm.sleep_mode=1
wifi.supplicant_scan_interval=180
#Response
debug.performance.tuning=1
video.accelerate.hw=1
#extras
persist.sys.use_dithering=0
ro.ril.hsxpa=3
ro.media.enc.jpeg.quality=100
ro.media.dec.jpeg.memcap=8000000
ro.media.enc.hprof.vid.bps=8000000
persist.adb.notify=0
ro.kernel.android.checkjni=0
ro.home_app_adj=1
windowsmgr.max_events_per_sec=150
Those are huge improvements to your system it will cause the system to fall asleep when the screen is off almost instantly which brings the phone into deep sleep..saving battery hard core
*tip-make sure system power saving in system in unchecked...
* and turn Auto-sync off in (Accounts and sync)..saves some battery
Hopes this helps buddy let me know...also as you already know let the battery get used to these settings with a couple days...my phone has the best battery life with performance when needed..
Thanks!
I never knew about the build.prop. Is that in all android phones?
I pretty much did the same as you except didn't oc yet.
I'm using system tuner pro to watch, modify and monitor. Also his battery widget pro.
I noticed CPU 0 gets used like I would expect. However, CPU1 is mostly 'offline'
Is this something that can be tweaked or baked into a kernel?
get rid of system pro..half the time those setting don't stick......yes build prop is in /system/buildprop folder....long press open with edit text and you can manually add those props at the end of the list...like as in the thread..easier just to copy and paste them...and save...reboot..and go back make sure they stuck...get set cpu for overclocking works flawlessly and cpy spy shows the phone on each setting the cpu uses and for how long..and you can see when the phone enters deep sleep and how long....showing that those two scripts work....

trust me cpu0 and 1 works....normally when doing higher process like games interent stuff...if where to be on all the time it would use more battery...this way the system can utilize the cores more efficiently
Do you guys tweak the sysctl.conf at all on ICS? I read somewhere that tweaking the OOM on ics will make it slower. Just trying to get the max speed out of this phone without overclocking.
Thanks
I used to tweak the sysctl.conf to get slightly better speeds out of my 3g connection, but with 4g I don't think much can top those speeds.
Is there any custom build.prop mods for stock ROM i can use.. Mostly like uncap 3g/4g speeds or 4g speed tweaks lol?
