If anyone has anymore info on the ro.ril. properties, I would greatly appreciate it.

It would also be great if every shared the script they use with which network.



You'll need a rooted Streak and Root Explorer.

Add/edit these entries to "/system/build.prop" (you must mount to r/w and open with Text Editor). Make sure that these are not already in your build.prop, if they are, then just edit the values.


ro.ril.hsxpa=2 (higher values are invalid until proven otherwise)
[0=UMTS] [1=HSPDA only] [2=HSPDA & HSUPA]

ro.ril.gprsclass=10 (Class 10 to save battery)
The Streak supports Class 12 GPRS, set to 12 to increase EDGE speed

ro.ril.hep=1 (no info available, no change when turned off)

ro.ril.enable.dtm=1
Enable "dual transfer mode" on EDGE networks; requires different GPRS class setting. Only set this to 1 if your network allows simultaneous transfer of Circuit switched (CS) voice and Packet switched (PS) data over the same radio channel (ARFCN).

ro.ril.hsdpa.category=8 (Cat 8 is the Streak's max)

ro.ril.hsupa.category=6 (Cat 6 is the Streak's max)

ro.ril.enable.a53=1 (enable increased ciphering on HSDPA/HSUPA)

ro.ril.enable.3g.prefix=1 (Adds the 3G prefix e.g. Optus 3G, etc.)


All Carries have their own specific settings they should use.

As Im using Optus Prepaid in Australia these are the setting I use. Lots of experimenting went into these and my 3G works better than ever. Best SpeedTest I've got was D2.98/U1.52 48ms ping on 4 bars, average is about D2.5/U1.0 80ms.

Code:
ro.ril.enable.dtm=0
ro.ril.gprsclass=10
ro.ril.hep=0
ro.ril.enable.3g.prefix=1
ro.ril.hsdpa.category=8
ro.ril.hsupa.category=6
ro.ril.hsxpa=2
ro.ril.enable.a53=1
Thanks to nickshertzer here are the setting for AT&T

NOTE
After adding, save and remount to r/o. You might need to restart TWISE to get this completely working.

Happy Streaking =)






This will not increase the power of your antenna or increase radiation. All this does is choose the best profiles for EDGE/HSDPA/HSUPA. Its proven to increase speed and connection strength.

NOTE:

This will not increase the power of your antenna or increase radiation, all this does is choose the best profiles for gsm/hspa, dunno exactly how it works, but its great for indoors where u dont get a good hspa signal

Thanks for putting this together nice work

TWISE? Sorry, I don't understand.

NVM - figured it out.

No offense, but you sound like a novice at Android development. Where did you hear about this build.prop tweak? Do you work for a cell tower contractor? Seriously I'm not trying to offend you, just confused.

I did my own research on google for these tweaks. They seem legit. Go have a look

It sounds make sense, modifying the RIL parameter. However I found those 3 lines a little bit .... maybe the first two lines are unnecessary due to our device is not HTC? And for all those lines, i think there should be no blank spaces between characters. I might be wrong though
