Sorry if this doesn't go here but I have a question for the gurus from XDA, so here is the deal.
Recently in Costa Rica we got our 3G network released, but they chose HSDPA/WCDMA at 850 MHZ.
I was going to get an HD2 but due to it's bands I think I can't now. At some store they told me that it was possible to flash a different Radio version that will enable the 850 band.
I tought that the radio frequency was a hardware driven setting but I guess my question is if this is TRUE.
Can it be flashed to make it work
Thanks Gurus!!
Pura Vida.

Hi, I have an Audiovox SMT5600 but my network band is 900 MHz.
Can somebody tell me whether it is a hardware difference between SPV C500 (GSM 900 / 1800 / 1900) and Audiovox SMT5600 (GSM 850 / 1800 / 1900) or is it just the GSM Rom??? I have read the thread (http://forum.xda-developers.com/showthread.php?t=241435) which explains how to upload the QTEK rom, but it didn't work for me.
I have found the following explanation but it doesn't say whether it is hardware difference or just a different GSM rom.
"The SMT5600 is a tri-band phone that works on the 850/1800/1900MHz bands, which means it will work anywhere in the US where GSM service is available. In the US AT&T uses both the 850MHz and 1900MHz bands, as does Cingular. 1800MHz is used in Asia and somewhat in Europe, though Europe is mostly 900MHz. If you plan to travel to Europe, the SMT5600 should provide some coverage, but you might want to consider a quad band phone which adds 900MHz. The overseas versions of the SMT5600 (iMate SP3 and Orange C500) are triband world phones with 900/1800/1900 MHz coverage which means they'll work in Europe, Asia and in the US though you'll miss the 850MHz coverage used by AT&T/Cingular."
If changing a GSM Rom is the solution, where can I find the 900 MHz Rom and what is the procedure to flash it? Can I just use the Typhoon tools and perform an Emergency Flash for the GSM part or do I have to replace the complete ROM (like with mtty)?
Thanks in advance!
The radio freq's are hardware, not software to my knowlege. AT&T Cingular in the USA have moved to using the 850 MHz band for HSDPA data packets and 1900MHz for voice. Since the SMT5600 does not support HSDPA, therefore the low band is not used. If your market is 900MHz only, then your phone will not handle it. In essence you would need the European version of the iMate or Orange version. Otherwise, you are constrained to 1800 MHz.
OK, but then what about kamscam's explanation in the thread I mentioned above (http://forum.xda-developers.com/showthread.php?t=241435)? He claims that flashing the phone with the QTEK Rom will do the trick.

I have the iMate 2.4.33.11 ROM if you want to try it. I believe it is WM2003 OEM Rom for the SP3 (Typhoon).
If the claim is true that he changed an 850 MHz phone to 900 MHz and it worked, then this would seem to indicate that the phone may be Quadband but the Radio ROM only operates as Triband with the 1800/1900 always on and the 850/900 as selectable. This may be a possibility, but I still have my doubts. I still believe there is a different hardware radio for the 850 MHz and 900 MHz models.
http://rapidshare.com/files/61129896/SP3_WWE_2.4.33.11.zip
There is hardware difference in C500 and STM5600 which runs on 850. Difference is in switchplexer which in European models filters 900 and 1800/1900 MHz (Murata HA 165) and in STM 5600 (Audiovox) filters 850 and 1800/1900 MHz (Murata HA 216AW). You have to change switchplexer on the board if you want 900 MHz on Audiovox
OK, I guess this concludes the story. I have actually suceeded in flashing a different GSM Rom (Qtek) but the phone still couldn't pick up the signal.
Thanks raskell and typakkk and everybody else for help!
I am very confused. my phone does not connect to 3g AT ALL.I have tmobile in usa in new york and I tried changing the settings in my phone options from gsm to wcdma and default the umts to 2100 and my phone stays on searching for service.. Can anyone help me out?? I want to be at 3g speeds not gprs... tmobile gprs is way too slow and it only works on GSM mode.. How do i connect to 3g with this phone? I updated my radio from 1.15 to 1.18 and I am getting the same exact results. This thing is driving me crazy, it just doesnt make sense.. someone please help me out, id greatly appreciate it
EDIT: Nevermind, i realized all of us HTC UNIVERSAL users are completely screwd because USA Supports only 1700-1900 Bands and the HTC UNIVERSAL only uses 2100mhz Bands.. NO 3G HTC UNIVERSAL IN THE USA. THIS SO SUCKS MAN.. =.-(

From what I have read on the Internet and speaking to a well knowledged person at a T-Mobile store the 1700 & 2100 AWS will be deployed in the United States. This is the same technology used in Europe on the 2100 UMTS WCDMA frequency. The T-Mobile representative had mentioned that New York City was using the 1700 AWS UMTS Frequency for voice & data but will also be deploying the 2100 Frequency later this year or early next year which last year T-Mobile was the highest bidder at the AWS auction and had also purchased this frequency but which originally the 2100 frequency was used by the government only for satellite transmission. Once the 2100 Frequency is deployed your radio will search for and if available find the 2100 frequency and connect to it automatically. You do not have to get a different sim card like AT&T which you have to purchase a 3G sim card. I am also anxious to get that frequency but is not yet available in my area. The best radio version is 1.15.
very very interesting... i cant wait till that comes then..

I disagree, usually with most software the higher the version number the better, and there is no evidence that 1.18 is any worse than 1.15 at all. I've been using 1.18 for around 1 year with no problems.
I was use a lot of times for search wcdma network name in shanghai , beijing or hongkong.
first , you need insert USIM card ,not SIM card to handset.USIM card is Support reg to WCDMA or GSM network.

You're post has been the most insightful writeup in regards to T-mobile US 3G I've ever came across, Many thanks!
Hello, I have a HTC HD 2, and I need to change the Radio Frequency to work with 3G for my carrier. I am using Telcel in Mexico and the frequency for 3G is different than what came with the phone so all I can get is Edge with this phone. Telcel's frequency is compatible with AT&T as I have used my AT&T phones without any problem with Telcel 3G so there must be a difference somewhere. This is what iPhone shows is its frequency so I imagine that the same would work with this phone:
UMTS/HSDPA (850, 1900, 2100 MHz)
GSM/EDGE (850, 900, 1800, 1900 MHz)
Any ideas or help would be greatly appreciated!!
Did you try any rom or Radio...
Maybe need to look something on setting...

Is your HD2 the European or the US version?
Version HD2
I beleive it is a US version but I bought it used off a guy on ebay... Any way I can find out?
Settings
We have gone into the settings and the settings are on Auto and we tried through the settings and advanced settings and the frequencies do not match what we need for Telcel so I am assuming some kind of modification can be done? Maybe it is in a hidden menu?
Not possible

Sorry pal, but Mexico, as most american countries, uses the 850/1900 3G UMTS bands...
The most common sold version of the HD2, the so called 'european', supports 900/2100 bands, so you won't ever make it work with your country 3G. IT IS NOT something that can be configured, or even flashing other Radios or ROMs, it won't change it.. it is hard-coded on the on board 3G chip.
Right now, if you really want HD2 with 3G in your country, your only choice is get the 'Telstra' version (T9193) from Australia (e.g. EBAY)... it supports the 850Mhz 3G band, so it should work on your country.
As i live in Argentina, i did the same, bought such version, and it works with my country 3G operators....
Really, don't even waste more time investigating this matter. you won't be able to do it.
Htc hd2
The only way than you can get 3G on Telcel networks its if you have the htc hd2 t9193 from AU..

Your HD2 must have been made for EU / Asia market: Model T8585 (UMTS 900/2100 Mhz)
The HD2 that's compatible with AT&T will be the only one from Australia carried by Telsta: Model T9193 (850/2100 Mhz)
How do you you know if this is Australia or EU/Asia verion - look at the back of the phone below the battery cover. If EU / Asia version, nothing would be showing but if it's Australia version you would see this "Next G network / T".
It's the design of hardware which can't be changed

Remove the battery and see the model! it it is T8585 then forget about 3G! You will never make it work!
Hi .. I was searching the forum because I want to purchase an HTC HD2 T9193 which, I know, has the 850 - 2100 Mhz band. But I found on the net a vendor who offers the HTC HD2 850 - 1900 Mhz band, is this right ?
On the other hand, if there is not such HD2 with 850 - 1900 Mhz band, the one with the 850 - 2100 band will pick up 3G in Canada ?
That model (850 / 1900) was supposed to come out (for AT&T most probably), but it has since been cancelled.
I'd be careful if I were you. You can find more info about it here
The Telstra model (T9193) supports 850 / 2100 MHz like you said. You'll need to check with your service provider if they support 850.

Yes. You'll need to check if ATT supports the 850mhz band IN YOUR AREA.
I'm in a North Shore Suburb of Chicago area and have excellent reception with my T9193 in the area. There are 3 dead zones I've found so far that repeatedly drops calls using the HD2's 850mhz band exclusively. Other unlocked phones I've previously owned that used the 1900mhz band exclusively did NOT drop calls in these areas however. Other than that, reception has been great. It's been reported that ATT is "supposedly" moving their entire network to the 850mhz band exclusively by end of 2010. I'm doubtful they are on target for this date given the number of cities still without any 850mhz support.
T9193
Hi guys ...thanks for your responses. Well, I know that the most important service providers in Canada (Rogers, Telus, Fido) transmit 3G in the 850 - 1900 mhz band. I suppose I will not have problems whether I use the T9193
hey,
im thinking about buying a t-mobile version of the G2 in the us.
but i thiunk its on the 1700 MHz. or is it also on the 2100MHz ?
because in germany i am on the eplus network and i dont know exactly on what band it is!
anyone having experience with that?
am i able to use the t-mobile g2 on the germany eplus 3G network?
thanks for your help
u should find some info about ur network's bands... if u cant , call them ... im with vodafone europ with tmous hd2 and its working fine with the 2100mhz 3g
Coming from the US, T-mobile has 1700/2100 mhz bands. I believe that means they use both
okay thanks,
i figured out that eplus has 2100 MHz and the phone im thinking about buying should have 1700 / 2100 MHz. so i guess itll work
thanks again!
Here's more footage on that:

The phone will definitely work in all GSM bands (Quadband) and the UMTS/3g Band 1700 MHz and 2100 MHz according to various internet sources.
