Hey I got a Desire, and I know this is not the right section but I was pointed here by people saying you might help.
I am in israel and my current desire device doesn't lock into the 3G signles here, however once i installed cynogen mod it locked into the HSDPA ( sp? ) network, which was awesome cause that was the first time I was able to get any time of mobile network signle here..

My question would be could I do this to my current sense rom? sorry for the noob question...

Thanks in the advance :)

hi you all!

I've HD2 MDJ's Android rom for daily use. I am quite happy about it but there is one feature which is, I think, depended on Android platform - not ROM.

My basic problem is that I do not have a strong cellular network coverage and it is really frustrating when phone is trying to get Hspda connection instead of staying 3G.

However I haven't found any solution to force phone NOT to try Hspda connection. Even old Nokia phones have option to avoid Hspda.

I am not sure but would this be possible? Came my mind after read this thread...

i think you are confused. not even old nokia phones can force to use 3G instead of HSDPA. no phone has ever been able to do that to my knowledge.

phones can only force to use 2G GSM, or stay on 3G/HSDPA. but 3g and hsdpa cannot be seperated apart, they are together as a technology and no phone has ever been able to block hsdpa but keep 3g UMTS that i'm aware of.

Besides, what difference would there be to only using umts in a low signal situation? Hsdpa or umts, its still the same identical cell site, tower, and technology you'd be connecting too. Why would umts be somehow better?

Only reason is that when phone is trying to get hspda connection "handshaking" and it takes always secs... and sometimes even more... this handshaking actually consumes lot of battery...

And I just check... f.e in winmo there is an option to disable hspda aka use only 2g & umts.

UPDATE: it seems that for some users is needed to do two reboots after each change of prop file.

It seems that is work for most users with rom based on DRC83. It seems that works in US and EU region. Therefore I decided to start separate thread (something was discussed in cyanogen's thread).
I tested it on cyanogen 4.2.7.1 but it should work with other ROMs too. I think that improvement is depedent on presence of HSUPA feature in your network.
Try it and let us to know....

Comparison video - two G1 simultaneously (sorry for poor quality-Nokia)
http://www.youtube.com/watch?v=bskKwh2xBXs

I have found that my cyan G1 is much slower in uplink in 3G network than official TMO EU G1. Same radio but "primary band" (phone info menu) was different....
Cyan (and other US ROMS):
62.50S.20.17H_2.22.1.26l
TMO EU:
62.50S.20.17U_2.22.1.26l

I found difference in build.trout.prop (build.prop - TMO) which make this difference.

Cyan (TMO US):
ro.ril.hsxpa=1
ro.ril.gprsclass=10
TMO EU:
ro.ril.hsxpa=2
ro.ril.gprsclass=12

I changed values in build.trout.prop.... TADAAA
62.50S.20.17U_2.22.1.26l is showed in phone info. Uplink is almost three times faster. It seems that is some improvement in EDGE too (gprsclass).

THEORY:
US ROMS has disabled HSUPA feature.
ro.ril.hsxpa=0 - UMTS r99
ro.ril.hsxpa=1 - HSDPA
ro.ril.hsxpa=2 - HSDPA/HSUPA

script which apply all stuff (thanks cloverdale)
note: script use cyanogen build.trout.prop
http://xdaforums.com/showpost.php?p=5081309&postcount=7036

or

1) adb pull /system/build.trout.prop build.trout.prop
2) edit with notepad++ (or other unix format capable editor)
3) adb remount
4) adb push build.trout.prop /system/build.trout.prop
5) reboot

in on other roms change build.trout.prop to build.sapphire.prop or build.prop depending which one your ROM using

    to summarize this...
    This mod could help in areas with at least 7,2Mbit HSDPA in downlink
    Definitely improve uplink in HSUPA area - without this mod isn't possible to break 380kbit barrier

    It will not help in case that you are blocked by operator's QOS (throtling, shaping)
    It will not help in interfered areas.

    Don't expect miracles in case your operator doesn't have sufficient technology.

    From previous post is visible that somebody experiencing huge improvement, somebody slight, somebody non improvement and some few degradation.

    Again this mod isn't an miracle which will improve 3G speed beyond operator's capabilities. It just enable higher coding schemes on your phone, that's all.
