While I am certainly much the [email protected]@b when it comes to upgrading a WinMob device I do know something of the networks.
In reading and flashing I have seen the below Radio ROMs in various posts for the US for at&t/Cingular and a different one for TMobile.
Cingular 2.25.11
2.61.11
2.69.11
TMobile is a continuous 1900 mhz network and at&t/Cingular is not. In some places at&t is 1900 and in others it is 850. (there is also the 2100 mhz umts but no need to concern yourself with it if you are using a Wizard) Still yet, in some places like Florida you will find both 850 and 1900 mhz towers active in the same area. Now, if one or more of these ROM's has a preference for 850mhz or 1900mhz it could account for a lot of problems. Further if one of these ROMs does not transition readily from/to 850/1900 it could also create issues.
Yes, in a perfect world the phone could transition from one to the other without a hitch but this is not a perfect world. Food for thought anyway since I have not seen this pointed out elsewhere in the forum.
Well I believe this is very interesting. I have has many many issues with Cingulars Radio ROM. and reading there forum the delivered Radio ROM (2.25.11) actually has a problem switching between data and phone. And they just dont care over there.
I am very interested to hear anyone's Ideas on which one works best for a Cingular phone in the US. I am still using the 2.25.11 right now and have to read if Ic an flash the Radio to a different version (I only have a hardSPL installed on my locked G4).
Well, anyway, very interesting point of view. I hope more people chime in.
Thanks,
SoBBie
I would think that the Radio Rom from a Unbranded HTC 8125 would have vanilla preferences and would likely transition from one band to another based purely on signal strength without carrier determined preferences, but this is just an educated guess.
By unbranded I mean straight from HTC. Not setup for TMobile or Cingular or anyone else.
Now of course the SIM card is loaded with a list of towers by vendor which your phone will connect to in order of carrier preference to keep you from "roaming" on someone else's tower which costs them more. When there are changes in your region the carrier sends out a "push" to update the SIM. Something I miss from my IPAQ is the ability to choose which vendor my phone connected to or I could choose "Automatic". But that is a discussion entirely different than this one... heh heh
Hey gusy I just got my Aussie HD with 3G on 850mhz but I think I crapped it up. I did a hard spl then went to a custom rom and now I have no 3g when I did before. Can anyone please point me in the right direction.
Thanks,

it would help if you tell us what custom ROM you used AND if that ROM included a Radio. if it didn't include a radio, you should be ok... also, can you get an internet connection? did try going into Phone->Menu->Options->Band Tab->and select WCDMA for GSM and the 850/1900 UMTS band -> click OK and then see if you get a signal? these answers may help us solve your issue.
OK so I found the telstra rom and what back to it. Still could not get 3G. But with that rom I did at least have the 850mhz as an option under settings, phone, band. I was for sure that Houston had the 850mhz but I could be wrong. So now I am on Rom version: 1:19:831:0 (25581) Radio 1.10.25.25. Let me try changing those settings like you suggested. Is your reception good up there in Dallas?
my reception in dallas depends on my location... at home i usually get a solid EDGE signal. i'll get a stronger 3G signal if i go outside. conversely, here in KC, i have a solid 3G signal everywhere i go. so what ROM did you flash to your phone? and did you flash a Radio ROM as well?

Not every area in the US is covered by the 3G 850mhz bandwidth by at&t. I wish the online retailers would put. May work in North America. I'm sure if you traveled around the state a bit you would find that your phone gets 3G in some areas.
I also have the option to select 850 and 1900 GSM & 3G in the settings.

May I ask what rom & radio you are using? The original Telstra rom & radio show under settings, phone, options, bands the 850 spectrum and a bunch of different combinations. I hate the tf3d on the telstra rom because it is loaded with all of there carrier stuff but I want 3G. It seems that when I change roms even if I keep the same original radio I lose all those band spectrums under settings, phone, options, bands. What would you suggest?

Well right now I went bacl to the telstra rom & radio because I seem to lose bands if I change rom even keeping radio the same. May I ask what rom & radio you are running?
i'm running Dutty's 2.1 ROM with the new Manila. i had the same thing happen to me: one minute the Band Tab (under phone settings) are there and the next they're gone. there are 2 fixes i use when this happens: (a) simply soft-reset and they appear or (b) use a registry editor to goto HKLM\Software\OEM\PhoneSetting and then change the setting for ShowUMTSBandPage to 1. Sometimes i have to change the other Show****Page seetings as well. right now, my device is set to Auto for BandType and Network Type and i'm getting the H symbol everywhere i go in Kansas City. i know that once i get back to Dallas, the same settings will cause my signal to vasolate between H and E depending on where i am, e.g., at home it will likely be E. if you didn't flash a different radio, you should be ok. like AllTheWay said, you're probably not in an area with a strong 850 3G signal.

no, Dutty's 2.1 ROM does not come with a radio. what ROM did you flash that cuased the BandPage to disappear?
I used the newest wwwe shipped rom. But the used udk's custom RUU and placed the nbh file from the old radio back into it.
Hey guys, I am considering getting the telstra version HD soon, I was just wondering what do I need to do to set up the phone for ATT, or is it good to go out of the box?
Also will all the phone features function normally with ATT? Thanks for any input.
Also wondering if i have read this thread correctly, as long as I do not change the radio and only upgrade the ROM after HardSpl, then I should keep the 850mhz 3g?
Same here I have a european version of HD. What do I need to install to get the 850 3G on ATT ? please advice

you need another phone, a.k.a., the Telstra Touch HD. you will not be able to get 850 3G with the UK version of the Touch HD.
the telstra hd (T8285) is good to go on AT&T and Tmobile in the US....
straight out of the box...
another question i have is that i have the EURO HD. (t8282)..
in the BAND TAB (under phone settings) i have the options
UMTS (850 +1900) +GSM (850+1900)
does this mean that my phone will get 3g on an 850 MHZ network?
like AT&T or telstra in australia?
cheers

Hi All, I want to know if I flash a new radio won't that change the operation frequencies? I mean I have an X1a in Australia and I got this phone so I can use with Telstra NextG (UMTS 850) when in the regional ares and bush. Isn't the Radio the part that determines what frequency it uses? I don't want to attempt an upgrade of radio if it means I lose this access.
Is there a way or utility to back up just the radio in the X1 in case of issues?
Another interesting point is that a thread and a site that shows the circuit boards of an X1 shows the power amps for the frequencies. I see it has all of the IC's in place for all the operating frequencies combined (X1i and X1a) does this mean there could be a way of not only quadband GSM but Quad band UMTS as well?
Sorry if these questions are asked elsewhere but I went through the Radio threads I could find and no one specifically mentions the frequency they are using.
Regards Ismael
Any help available?
Radio frequencies are governed by hardware, not software. By flashing a different radio, you may find improved / worsened reception, data speeds and battery life.
Just make sure you are flashing a compatible radio, most people agree that if possible to have matching rilphone.dll installed as well. Can't stress enough tho that you want to make sure both radio and rilphone are compatible, otherwise, you may face a hard reset.
Phone Radio Compatibility Details Requested (both general and US T-mobile specific)
I have been doing a lot of researching regarding this phone and all of its cousins as well as how they will operate on the various US carriers. I have the following requirements for my next phone purchase:
1) Must be an Android device
2) Must have front facing camera (for international video calls to relatives)
3) Must be GSM (for compatibility with local prepaid SIM cards when traveling)
As AT&T and T-mobile are the only two carriers in the US (the only two viable ones at least, I don't know if any smaller carriers use GSM) and I refuse to renew my contract with AT&T that narrows it down to one option.
I have been researching the different carrier frequencies, both what they are and why they are different. It seems T-mobile decided to be special and as a result it is nearly impossible to get a T-mobile high speed compatible phone unless you purchase it from them directly. I almost want to call that evil, but it is easy to believe that is just a bad side effect rather than the intent.
Anyways, as we all know the Galaxy S has been severely nerfed by everyone except for Sprint. If Sprint only had a GSM phone that I could use internationally I would pick up their model, but alas it is not. I will not purchase the Vibrant because it lacks the front facing camera. My last option is the unlocked Galaxy S available abroad unless I am missing something.
Most of the online retailers I have seen all list different band frequencies and not even all of them have it divided into 2G/3G frequencies. I have some specific questions, but if you have any useful information for me I would appreciate it.
Question 1: Do the online retailers just suck, or are there truly many different frequency bands for the unlocked Galaxy S?
Question 2: Does anyone know of a Galaxy S phone that is fully compatible with T-mobile in the US (not the Vibrant, I need the front facing camera)? If not, would it be good enough?
Question 3: The radio bands I have ready about are usually divided into 2G and 3G categories. Is the phone radio physically divided into one for 2G and another for 3G, or is it the same radio and those are the frequencies USUALLY used by the different speeds? If I see the appropriate T-mobile high speed frequencies listed under 2G, would that mean the radio is in fact compatible with the T-mobile 3G because the radio can talk on that frequency, or is the hardware actually different and unable to comprehend the 3G speeds?
Bumping my own thread and also wondering if anyone has any recommended vendors to buy the international Galaxy S in the United States.
i bought mine from handtec.co.uk and it is working ok..
beware though that at&t unfort. in my error has been slowly getting rid of 1900 3g and more 850 3g which does not work on the phone..
at least at home the microcells are 1900 3g.
Radio chip/antennae changes?
It seems the internal Galaxy's electronics is all the same or modular. Is there a chance to take the radio module out of T-Mobile body and put it into the Sprint's nice hardware? How easy it is to obtain the desired component?

[Q] Which CSC (Phono/radio) version will give the best results?
I'm wondering what CSC-version (Or is it the Phone/Modem?) will give the best results in The Netherlands with Vodafone as telecom provider, or maybe... where can i find the stock version of the radio (and is it possible to use it with a root?)
I'm using Froyo (I9000XXJPC) - Rooted, but I'm wondering if my connection isn't worse since updating, I believe my 3G/HSDPA is weaker since then.
Anyone the same problem?
I also have the same problem, but already since upgrading to jm1 trough KIES.
I think we need a i9000XEN CSC.

Is the "i9000XEN CSC" the stock one?
I'm not on JPC but changing from JM3 to JP2 (modem) actually makes my GSM signal and wifi sort of worse, dropping 1-2 bars at the exact same location compare to JM5
CSC has NOTHING to do with reception or 3g whatsoever... its just branding stuff and APN etc...
the MODEM file is the one you need to look out for!
Right now i'm on JM1 (rev03) with the appropriate modem file and i have no problem whatsoever!

You sir, are wrong.
I have a Bell I9000M and flashed the new HK JP2 Froyo to it. I lost my 850mhz UMTS Band. I then flashed back to stock JH2, including the modem and still no band. The only thing that fixed it was doing the *#272*xxxx# CSC select. Once I did that, bingo, 850MHZ Reception.
I know what you're saying SHOULD be correct, but unfortunately, it is not.
I'm still correct! CSC contains carrier costumizations. Which also can contain settings to ENABLE the 850mhz radio band!
BackfireNL said:

So, enabling/disabling a band doesn't have anything to do with reception?
So, when I get no reception because I'm in an 850MHZ ONLY area, which is disabled by the CSC. The CSC has nothing to do with it? I don't see the logic there, but alright.
You can use whatever CSC you want as long it enables the 850MHz band. It doesnt matter what CSC...
Modem file is the one that contains the drivers for the radiochip etc... A better modem file means that you can get higher 3G/Wifi speeds or even have better reception.
The CSC only contains the setting to enable the band.. nothing more nothing less

Which was wrong. No service due to CSC = No Reception. Plain and simple. You can argue what you meant all day, it's not what you said.
I'm done with this. I apologize to the OP for having this thread turn into this childishness.
Have a good day.
BackfireNL is right. Selecting a CSC indicates which band/frequency the radio will use according to the place you are.

Uhh, that's what I said, disagreeing with his "CSC has NOTHING to do with reception" comment.
Just so you two know, the actual Merriam-Webster definition of reception is:
"the act or action or an instance of receiving"
CSC not allowing 850MHZ = No Reception.
If you're taking about small increases/decreases in quality of reception, then absolutely yes, CSC has no effect. But that is not what was stated.
Confused...
Okay... thanx, both of you!
I've learned a lot new thinks...
Finally... I understand that I must use the Modem file if I have issues with the reception of the 3G network, but which version should give me the best results for my provider (Vodafone/Netherlands) and the new Froyo (JPC), and where can I get that modem file?
The Radio Chip in the SGS

That is the chip, now if I understand that right, it is a Pentaband radio. So that would mean it is all locked out in software.
No?
Users in the U.S., What Radio are you using?
I am running CFLagFix1.60(StockXXJF3) and using AT&T.
Everything works fine, except for a weak signal.
I can receive and make calls, but at times have calls dropped.
My home is in an area where there is a weak signal.
I am not try to get 3G, just a stronger signal.
May not be possible, but worth a try.
Signal is fine when not at home.
I have tried the following Radios without boosting the signal.
MODEM_I9000XXJF3.tar
I9000UGJH2-Modem
MODEM_I9000XXJP2.tar
bell_I9000_radio - No signal with the bell_I9000_radio
Any suggestions, or is it a lost cause?​
Is this a haiku?
PS It would help telling us what carrier you are using it on.
Had a look in the Radio list but didn't recognise any radio specific to 3UK and wouldn't recognise its number from Adam anyway.
I'm running latest 4.4 GPe Radio with AICP 4.4.2 ROM (AOKP Based) but always seem to have poor signal even though I know I'm in a strong signal area. Just wanted to experiment with their radio.img to see if it has any effect.
Thanks in advance,

you can experiment with different radios from here: http://forum.xda-developers.com/showthread.php?t=2419699
but are you sure it's not just "cosmetic"? you could use something like "Network Signal Info" available in Play Store to see the actual dBm strength.
