My question is that i have a Sprint Galaxy tab. I won it and dont plan on ever activating the 3G portion of it (no need to when i have free hotspot on my phone). My question is that since i dont need the 3G radio, can i flash a GSM rom? I would assume most things are the same inside besides the radio? Basically i want to flash CM6/7 and try it.
Just realized i posted this in the wrong forum. Sorry, please move if needed.
No. You are on the right path, but not the radio that's different. The antenna that receives the signal is different. CDMA antenna cannot read the freq range of GSM Antennae.
Right, and i dont care about CDMA or GSM reception. I'm using it as a wifi only device. So can i flash a GSM rom if i dont care if i lose cellular reception?

Is this possible? And if so can someone send me a cab file or instructions on how to make this happen. And sorry if this has been addressed already. This is my 1st official post. I have an AT&T Tilt with STOCK HTC AT&T ROM. Just upgraded the HTC Camera with one of the cab files I found on this site. Also I am having a bit of difficulty uninstalling two applications.
Wizard_reTouched_dial2.cab and today_wallpaper_pack.exe
I went to the normal start/settings/system/remove programs and I see them both in the list but i am unable to uninstall them. HELP!!!!!!
As long as you have a 3G / HSDPA / UMTS signal, you will be able to talk and use internet at the same time. If you are only on edge or gprs, you can NOT. This is covered many places in this forum........ Searching is your friend.....
Hey i'm using an AT&T TILT on Tmobile's Network with Stock Rom from HTC "AT&T's"
How can I force my phone or get my phone to use something other than Edge?

Travel to a location where there's clear 3G reception. Unless you've configured your phone away from default settings, it'll automatically default to the most useful signal it can get.
If you're using the stock ATT ROM then use bandswitch. If you're using custom ROM then it's in the phone settings. I use Garmin DK3 Final and it's in the phone settings. I can set it to connect only to UMTS band and only to HSDPA. I cant stand the 2G buzz when ever I'm around any speakers.
Are you referring to the Radio Version
or the actual ROMPaq? I am using AT&T/HTC Stock Rom but I am using the Radio Version from Japan.. 1.71.09.01

From what I know of, Japan uses a different frequency band than the rest of the world for 3G (800MHz). So you might not be able to connect to 3G networks in the US with that radio version. Do you ever see a "3G" or "H" icon for the network status?
No only E of course for EDGE
Cot Darnarbit!!! I might as well go back to the STOCK Radio Version I was running.
hello all, this is my first post here.
I do NOT have a data connection package on this phone (i don't know if this effects it or not), but whenever i go into a 3G area my phone loses signal and gets none whatsoever. I only get signal where there is an Edge connection. I purchased this phone used so there is no warranty or anything. Ive taken it to [email protected] and they say that the only thing i can do is buy a new phone , but i love my phone. Is there anything i can do to fix this?
Flash a different ROM. My roms in the sig are TILT roms and will work in 3G and HSPA using ATT in Houston. Just make sure you get the connection settings right. The problem with your connection cutting out has to do with a combo of the ROM and the radio.
what are the right connection settings? and do i need a new radio? which radio would work?

Go here. And read the Guides section for the radio and how to flash, most roms require you flash the stock one on there first so go to HTC->support>choose your product->download the latest rom image, it should be like 119mb or bigger. For the settings, do a search on here for ATT connection cab. it will set up the connection without you doing anything. if you can't find it I'll see if my friend can post it somewhere.
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!

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
ht tp://ww w.triquint.com/prodserv/more_info/proddisp.aspx?prod_id=TQM6M9014
(remove spaces)
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.
I have a factory unlock international SGS version. I'll be moving to Toronto Canada soon. I would just like to know if my phone will still work when i arrive there. If not, is there a way for me to make it use 850mhz? Does is help if i'm running CM7?
Thanks in advance for the help!
mike
your phone is the international version, so it will work all around the world.
i assume your not a noob when it comes to flashing as you are currently on CM7 (not the easiest rom to install)
so if you do run into any trouble - mainly signal issues (which you shouldnt) a simple modem change should work
but i use JVO modem in UK other people use this modem in India, Australia and so on, works for them, works for me... you will be fine.
You will be ok as long as you have an 850/1900 modem

Thanks bro. The reason i'm asking here is because i read on several forums that not all SGS international phone have the hardware to support 850 band frequency. Meaning even if i change the modem that support such frequency, it won't work as there's no hardware to support it. But then again, I don't have any idea if this are true. Would you know any truth about this?
Oh by the way, at first i thought installing CM7 is hard, but once you finished reading the install instruction everything is smooth as butter.

Just want to ask, if i don't use modem that has these frequency (850/1900) for my cm7 sgs, would i still be able to use my phone? Please correct me if i'm wrong, these bands only lets me connect to 3g or hsdpa and has no effect in terms of making and receiving calls/sms?
Thanks again!
I don't think that is true at all, it's not a hardware issue, it is firmware, you just have to make sure your baseband firmware supports 850.

These bands are what connect your SIM card to carriers.. so yes you need these bands. Whatever carrier you are with will depend on your band.. in Canada for example. Bell and Telus use both 850/1900 mhz bands depending on location, Rogers I believe on uses 850... so if your modem, is 1900 only and you are in an 850 area, then you will have no signal and usually recieve an error like "SIM not compatable with carrier" if you try to force a connection.... the APN(access point names) are what connect you to 3g etc..

Cool! Thanks for clarifying this to me bro.
I've accepted the lack of one of the T-Mobile radios in the HTC One phones. The only way to get all their radios, is to buy the T-Mobile version. For those who get any other version (in my case, a Developer Edition), the missing radio seems to means that if you don't get LTE coverage in any given area, you are stuck with 2G Edge.
The following question may either make sense or sound totally ridiculous, but here goes:
Can someone build or buy a separate radio device that would "pick up" and/or convert data from the missing range to LTE or Wi-Fi, so the phone could access it?I might not be asking this properly - but the end result would be a small box you'd carry around along with your HTC One, and when you wanted to do something that used "data", this box would allow you to access faster T-Mobile connections than 2G Edge.
T-Mobile wireless hot spot. That's what you want
http://www.t-mobile.com/shop/phones/default.aspx?shape=mblhsp
Not quite - to use those, you need a separate SIM card with a separate data plan. I doubt if what I want is even possible, but I'm asking in case I am wrong.
What I want, is a device that would somehow give my phone access to the "3G" band on T-Mobile. Currently, it apparently only has radios for LTE and 2G.
