HTC Touch Diamond US 3G - working ROM

Is there a working ROM (home brewed or otherwise) that will make the 3G in HTC Diamond work in the US with a carrier like ATT?
I would like to buy a phone and I am not sure if this is possible. I read somewhere that the FCC recently approved 3G version of the model - but would like to know for sure.
Thanks,
Karter

No, there is no ROM. The European Diamonds don't have the hardware necessary for getting anything but 900/2100mhz 3G. Try searching before you ask questions that have been answered 5 times over.

Ok now I'm really confused ! I thought the fact (or at least I thought it was) that the "European" Diamonds were ROM upgradable to access US 3G was the whole basis for those of us that are hoping for the Touch Pro to eventually be the same way ??????????????

Sorry guys - I must have misunderstood some of the posts and I haven't been following the Diamond area closely enough
But I sure am glad I could provide you some entertainment ... but even more so, I sure hope that the when the dust settles the laugh will be on you ???
hopefully

yes yes the manufacturers want to give out all those free features..i forgot how the commercial world works...

that is not entirely true. The hardware is exactly the same.

Please don't perpetuate this false rumor - DIAM 100 is not 850mz 3G capable
Based on the fact that HTC submitted a different model number than DIAM 100, the DIAM110
http://gullfoss2.fcc.gov/oetcf/eas/...mFrame=N&application_id=417017&fcc_id='NM8DM')
to the FCC, it seems pretty clear that the hardware between the European version and the US version are in fact different. In addition, no one has been ale to get 850mhz 3G working on any existing (i.e., DIAM100) phone. If you can show evidence otherwise, I'm sure people would be interested. Otherwise, I think you're spreading a false rumor created out of wishful thinking and HTC's past behavior of not enabling GPS on the Trinity.

Indeed there is no evidence to prove the DIAM100 can work on US 3G. But, i dont think its hardware related well i just keep my hope that something can make mine work. Dont want to sell it out!

lets speculate a little....
1) Mobile phone chipsets ARE multiband by definition. Even if it says that it is only 1900MHz, its chipset suports a range of frequencies (something like 1850 to 1990). Why? because it has to support lots of call in a single cell. The call are spread over hundreds of channels (frequencies) and across time-slots in a code division scheme.
And because it uses a code division scheme for multiple simultaneos calls, then all these frequencies are used at the same time.
So, operating frequency is programmable.
2) The Antenna has also to support multiple frequencies.
3) I think the only reason a chipset has to not support a frequency is the processor speedy. But 7201A specs says it suports 2.1GHz as well as 850GHz UMTS.
So, the reason a mobile phone has to be dual band and not quadband has to be only market related and not technical.
Is this correct?
or only bull****?
If this is correct, then Diamod Hardware HAS to be UMTS Quadband.
And, to provide HTC a commercial advantage when negotiating with carriers (that is, HTC locks european models to not work in USA --- so that, to use 3G in USA one needs to by the device from the local carrier --- this leads to better contracts with the carrier).
If Diamond hardware is quadband where is the lock?
From all the reseaches we are almost sure it is not in the main storage memory (Radio or ROM).
It can be hardware locked....then the only way to unlock will be hacking the hardware wich is not viable for almost all of us (if it is not impossible).
But (trying thinking as HTC engineers), how about lock it (outside the memory --- because users are flashing hacked Radios and ROMs) but still in a programable way? (I think like sim-lock is done this way in many devices). Because doing this way I don´t have to create diferent production pipelines and different projects.
By programmable I mean a process that is done after the phone (or the main board) is manufactured.
If all of this is true (and I think it is not ) than the question is: is this final process reversible? (like simlock)?
If yes then how?
Uau.....I am impressed on the amount of **** I can write sometimes.

US 3G Touch Diamond is here

Hi guys and gals, we just got our hands on the unlocked GSM version of the Touch Diamond for the US, with US (err, AT&T) 3G. Here's my first look: http://www.mobiletechreview.com/phones/US-3G-HTC-Touch-Diamond.htm .
It has 850/1900MHz HSDPA, and is quad band GSM. Short summary: no front-facing camera, matte back and bigger battery.
- Lisa

Has anyone been able to confirm whether the DIAM100 has hardware that can support the US/AT&T 3G?

nice, thats awesome!

No, the US version is the DIAM110, the DIAM100 won't do US 3G.

Sigh.. A different version (DIAM110) really breaks my last hope. I am sure many of us were misled to purchase the non-US model; with chaotic origins from India, Europe, HK, etc, without knowing (1) the claimed 3G couldn't be ued in the US and (2) a US model would come as we are seeing now .. Or is it just my ignorance and mistake? .. Hope some lawers on this forum could help us trade our whatever Diamong with a US Diamond with 3G/DIAM110.. My first and last purchase with HTC for sure.

Unfortunately it was a known fact that the Diamonds sold prior to the actual US release were not intended for the US and the specifications clearly showed (htc.com) that it was not US 3G capable. Problem is there are so many bad resellers that will tell you anything to get you to buy from them. I also have noticed that a lot of the on-line resellers dont list the correct information for all phones however HTC is not at fault for that.

And at the original launch of the Diamond in London back in June, HTC did state that a US version would follow in a few months. We posted that in our news section at the time. Of course, given the often long lag before we see a US version, many folks were skeptical it would really come this soon.

I would love to be directed to any statement on the htc.com website that clearly told the visitors that the Touch Diamond doesn't have 3G in the US.. I have to confess that I noted LATER that the htc.com content is country dependent, but I haven't been promoted to go through all contries listed on their map before I knew that 3g in the US is a catch..

There is no FM
The article states two things I am not enjoying at the moment: there is no front-facing camera, and there is no FM.
Also, it says that a hack could bring the FM back... is it true?

But if you look at the specifications it doesnt list the US 3G Bands. You would have to know which bands are used in the US to catch this. The point here though is HTC has not marketed this in the US. I believe all of the retailers of the foreign HTC phones sell the phones without the blessing of HTC. The problem is there are a lot of suckers here in the US with no patience and make the resellers rich by paying exorbitant fees for phones that were not intended for the US market. I am included in the list of suckers.

"Network HSDPA/WCDMA: Europe/Asia: 900/2100 MHz
Up to 384 kbps up-link and 7.2 Mbps down-link speeds
Tri-band GSM/GPRS/EDGE: Europe/Asia: 900/1800/1900 MHz"
http://www.htc.com/europe/product.aspx?id=46646
That's from HTC's Euro site. No mention there of US bands, just Europe and Asia.
Their US site doesn't list the Touch Diamond at all, since they don't offer it here. Though I'm sure they'll update the site to add the Sprint Diamond, and thereafter the US 3G GSM version once they officially announce it.

I said a hack *might* re-enable FM. The good coders here can help with that more than I can, I'm sure. I'd like to get the FM cab from the Euro Diamond to see if that works.
GSen works just fine though . Happily rotating anywhere I please.

pdagal,
Good review. Is there any notable difference in performance between the unlocked GSM version and the Sprint version, or do they basically perform the same?

Thanks . There's more to follow. I'd say the Sprint version is still a little bit faster. The Sprint version has more obvious bugs though (call send button doesn't always bring up the dialer screen, landscape mode extends to apps it shouldn't support after launching a landscape app). I wouldn't complain about the landscape bug, but the device slows down when it goes into this "extended" landscape support mode.

pdagal - say you could have either one for your personal phone and you didnt mind going with Sprint or ATT. Which would you pick and why?

I'd like to play with them both a few days longer before issuing a verdict . Right now, I'd lean toward the Sprint model, though CDMA really isn't my thing (can't live without SIM swapping). The Sprint version is a bit faster, TeleNav (aka Sprint Navigation) is very good if you don't mind a monthly fee, and Sprint TV is moderately entertaining. But I'll try to remember to post back in a few more days after I've had time to torture them both more.

Thanks - Those are the two reasons I have been going back and forth in my head as to which way to go. The only two reasons I still keep thinking about Sprint is for the navigation software incorporated and having the Sprint TV service (although I do have a Slingbox). I used the TeleNav on a Instinct for a few days and found it very nice.

This is so bloody typical. You go out of you to buy a phone that is not sold in your country and then lawyer up to soothe over your ego.
Now youre going to blame the manufacturer and the shop owners for not treating you like the 6 year-old you seem to be and force them to eat the loss for your impatience.
If i was the judge sitting on this one i'd dismiss the case with costs to you.

I have a 110 on ATT in USA and find EDGE surprisingly useable. It is quite easy to use WIFI for large downloads. I can use for real time GPS maps (Google or Live). I was going to buy US version for 3G but don't think I need to.
The phone was sold IN the US through Amazon.com. No mention of it being Euro or no 3 G for US. I took a chance hoping a ROM would fix it but don't care now because it works so well.
Cheers.

In my particular case, the diam100 was advertised (by the importer) as 3G-enabled for my country. As it failed to comply, I'll return it and get a US when available. My DIAM100 is safe, packed and ready for a swap.

[Q]US 3G Limitation?

Hello,
As you can guess, I'm new to Blackstone. I have what I hope to be a simple question. Is the fact that HTC Touch HD doesn't support US 3G a hardware limitation or a software limitation.
Reason for asking:
When a US carrier gets off their lazy a** and picks up this awesome device, will there be a ROM update to enable US 3G?
I really want this device and the only thing keeping me from getting it is the 3G limitation, but I can live with it if one day (less than a year) there is a ROM update to enable US 3G. But if it is a hardware limitation then I'm out of luck.
Thanks,
Roger

hello,
just as new as you...got mine but knew it wouldnt work on us3g becoz us and europe have diferent types of network band for the 3g that why it wont here... hd was made for conveniently europe networks bands

Hardware or Software
I was aware of the limitation right off hand but do you know if its a hardware or software limitation?
AS IN:
Difference in protocols

Different Chip All Together

I do have to ask, due to this happening to me as well, when asking about status or news on 3G in the US for the HTC Touch HD everyone refers back to the link above for the "HTC to USA: No 3G..." message-thread.
I dont see the issue with asking the US 3G status question and getting a reply, rather than wading through 15 pages of postings in a huge thread. Discussion of everything from EDGE speeds, to speed-tests, performance in different areas, etc... but the question posed here is quite specific. Personally I've tried many searches and just looking to find status and how, if at all, I can help. Can we at least start a new thread to this end?
* Can anyone share a simple software/hardware issue for UD 3G with the Touch HD?
* How can [new people] people get involved to look into this kind of an issue?
Thanks for listening and any information...

I think maybe people are somewhat brusque when answering this question because it has been asked so often with respect to other devices. That being said, I do not think anyone knows whether the issue with the HD is hardware or software related (please correct me if I am wrong). I know that some members have been working on making US 3G bands work for the non-AT&T Touch Pro (http://forum.xda-developers.com/showpost.php?p=2565338&postcount=2), so you may want to ask those guys how to get involved in starting up a similar project with the HD.
I would like to say, though, that I have been simply amazed at how well Edge has been performing on the HD. It is faster for mobile browsing than my US 3G Diamond, Touch Cruise, Tilt, and my wife's iPhone 3G with the 3G/H showing and all bars up. So if you are putting off a decision to get the phone based on mobile browsing speed, in my experience (and it is just that, my experience), I have not missed 3G at all.
I note that that I have been using the HD in New York City with AT&T, which means notoriously crappy service no matter what the technology the phone is capable of, and, of course, tethering, etc. might be a whole different story, so I realize that my experience is of limited use. Also, I am going to be in a Euro standard 3G country soon, so I may be singing a different tune once I see what the HD can really do
Anyway, just my 2 cents, and I wish you luck. If you get a project for 3G going, I will happily donate, as, I am sure, many other will, too.

The only GSM carriers in the US offering 3G capabilities are AT&T and T-Mobile. For 3G on the T-Mobile network, your phone must support both 1700 and 2100Mhz. The 2100Mhz bandwidth has been well-defined as the "D" (download) portion of HSDPA. I believe you will also see 3G referred to as WCMDA on the 2100Mhz spectrum. AT&T Wireless has opted for a more "standard" approach where they are reusing the original PCS frequency (1900Mhz) for the "U" (upload) portion of HSUPA.
To get true, bi-directional 3G, your device must include a software radio that supports both HSDPA and HSUPA. Anything else will be a hit-or-miss affair. While this may lead you to "rejoice" because our radios are software-based, be aware that the antennas in our phones are also a part of the equation.
Therefore, you will likely be able to use a Touch HD on the AT&T network at 3G speeds, but you will NOT (EVER) get 3G out of a Touch HD on the T-Mobile network in the US.
It's a real shame that T-Mobile chose to deviate from its parent (Deutsche Telekom - T-Mobile in Germany) on their frequency choice for 3G. It makes them odd-man out virtually world-wide. I suspect that they were unable to secure the rights to anything other than 1700Mhz, but I would argue that theie decision really crippled their users..... it's yet another reason why I would NEVER buy a G1. Really sad IMO.

simple and straight answer:
its a hardware issue ... you won't get US 3g on touch hd, period. (no rom update etc. will make it start working)

No this is not true its a political issue, and the past shows already that it#s only a software issue, because the frequency range is so close to the European that the antenna is capable of those "between" frq.
The same is with Australia where some phones were original not capable but thr radio updates worked (nonofficial)
just my 2c

this is not a hardware issue. i know it has been mentioned else where in this forum and others, and we got "official word" that this is a hardware issue. but it is not. i didn't speak up earlier because i know if i did, people will ask me for sources. i don't have sources, i know because i work on these type of stuff.
in simple terms, the hardware is just an antenna, it is the "software" that should be tuned to interpret the signal. just like you can use regular analog TV antenna to catch over the air HD signals, it is the tuner that does the job.
however the software you are thinking (cab files or ROM files) won't solve this problem:
the hardware isn't flashed with the firmware, it is not enabled in the low level to understand the language EVEN IF the ROM file and high level application allows for the functionality.
everyone's familiar with computers, an analogy is: if you disable say sound in the BIOS (by using a older/different version of BIOS), you can install (what we call "FLASH" in the mobile world) OS you want, and you can install different audio drivers, you are not going to get that functionality.
so that is why you can flash left and right different Touch HD roms, you can enable/disable different registry keys that make it look like it has the 850MHz choices in the drop down menus, and you can always try different Radio ROMs, but you are not going to get a bit of that functionality if the hardware/feature is disabled at the lowest level. you need to flash the actual hardware (in this case the anthenna//baseband) with the correct firmware. and i am talking about the real firmware. I think the misconception here when everyone's talking about "i'm flashing my Radio's firmware to the latest one", they are actually talking about the equivalent of a "driver" in the windows world. the real firmware is even lower than those "firmwware".

Hey buggybug0
I read through your comments and it seems very logical to me. However, do you think that it is possible in the future that the us 3g band will be enabled through a "hardware flash"?

I cant wait until that day happens. So I should buy now so the price premium isn't higher. . . . .How long does it usually take to take a phone that has the bands enabled already then some how incorporate that FW with the one on the HD?

this hardware flash already exists, but because we are flashing a lower level hardware, you need a special cable, in addition to the binary file. only HTC has this special development cable, the cable plugs directly onto the board (not the miniUSB or extUSB port). we can't use the extUSB port because this port has no access to the memory that governs the baseband low level functionality: this is much like the older computer BIOS which you can only flash through the floppy drive. i believe windows mobile is behind windows, so this is where things are right now. nowadays you can run a high level .exe file in windows and have it access and flash the low level BIOS, may be some day this will become possible on windows mobile with a cab file flashing the low level baseband. but for the time being, the analogy is you need a special cable to flash, just like you need a floppy drive to flash.
everyone kept on saying lack of US 3g is a hardware difficulty, i know for a fact that this is a business decision. as much as US loves gadgets, europe and asia are much bigger markets, (the coolest phones always gets to europe, korean, japan taiwan first, other than a certain fruity brand). i don't doubt when HTC said "by the time we bring Touch HD to US, there will be much better phones, they are using this one-phone-for-you, one-phone-for-me strategy to keep customers hooked--> they disable the US band, and make the touch HD exclusive to europe, so North AMerican customers are all drooling, when the next gen phone comes that and improves on touch HD (call it HD2 for argument sake), they will release it to another regional market (for example US), then all european people will all get jealous and hooked, and get their interest up while US customers are paying big bucks to get them, so the 3rd phone which improves upon the HD2, and release it in europe, they will be all over it. it's a very good strategy because customer never loses interest. becuase you always want something you can't get. and you DEFINITELY want something that is better than the previous gen which you can't get. this for HTC means that the demand for their phone is always there at a healthy high level.

So what was up with the TyTn and TyTn 2.
Were they not able to do both US and EU 3G speeds? I don't recall there being different EU and US versions (like the Diamond).
I was using a Softbank X01HT version TyTn and was getting HSDPA speeds.
I would be surprised the HTC decided to cripple the phones since.

yes, there are HTC phones which had the same "BIOS", but the band were only disabled at the "driver" level, so the european brands of the same phone gets one Radio Rom while the US version gets a different Radio ROM. but since the functionality is already enabled at the lower level, it's just a matter of using a different radio rom (ie. driver) to enable the US 3G band.
I am not sure if the phone I am talking about is TyTn, but what I have same in the past 3 posts applies to a regular phone as well -- antenna is capable of receiving any frequency, it's up to the manufacture to insert the baseband software (this is the low level) to interpret those signals, then the interpretation gets passed onto the Radio stack (driver, radio rom), from there it goes to the operation system (winmob, symbian) then translates into applicatoin language to the actual application that's using the data (internet explorer, cell phone, IM app).

Your postulation could very well be the case. The fact remains that T-Mobile has created a 3G island for themselves and their subscribers here in the US. In my corporate discussions with T-Mobile, they demonstrate to me time and again that they simply do not "get it". Sad, very sad.
Only reason I stay with T-Mobile is the old (and I mean REALLY OLD) plan I have with them that no one has been able to beat cost-wise (plenty of minutes, unlimited data and hotspot access). I don't stay with them because they are at the top of the heap technically!

Well for those interested in the numebrs aspect, I have both the US and EU Diamond.
I tested both at dslreports.com using internet sharing. Same ROM (duttys 3.2), Same Radio (.05) , Same Laptop (via USB cable).
EU version (at EDGE speeds) came back at roughly 150 kbps.
US version (at H speeds) came back at roughly 450 kbps.
Of course this would only specifically apply to people in my area (Minneapolis). But it might shed some light on speed difference.

buggybug0,
until you provide your sources, your conclusions will remain a speculation for most of forum members. What you are saying may sound logical, but HTC may have different logic than you and you could still be wrong.
I agree with you that disabling 3G bands is a political decision though. And it's a commercial decision too. US carriers are apparently not looking to subsidize latest HTC handsets just yet for various reasons (T-Mob - due to G1, AT&T - due to iPhone 3G). However they will be shopping for new handsets sooner or later. If HTC releases a proper 3G quad-band device now, US carriers won't be happy and their further contracts for subsidized phones (which mean big money with no marketing/retail headaches for HTC) may never come in... Do they want to risk this big chunk? No.
Chances are you are right about the nature of band limitation problem and RF IC microcode may be crippled to support only certain bands on latest HTC devices. But it's still possible that some tracks are missing on the antenna PCB too. According to Qualcomm functional diagrams, it should be possible to multiplex RF signals for specific bands only.
This said, here's a challenge for you, prove your point with facts rather than speculations and you'll be a hero for a day.

Touch HD

Question #-1: How can I get my hands on one of these? I called HTC and they stated that this is not offered in the US.
Question #-2: Now should I be able to get my hands on this device..would the radio work on T-Mobile's Network?
Question #-3: What would be the potential cost? I can unlock it myself.

Suggest you go to the correct forum.

Question #-2: Now should I be able to get my hands on this device..would the radio work on T-Mobile's Network?
Question #-3: What would be the potential cost? I can unlock it myself.

Just because I have the time.
1. You need to buy an unlocked version online, just google it.
2. It is GSM and unlocked, it should work with T-Mobile, but is not compatible with any US 3G networks. So for now only 2G
3. You can only but it unlocked, I have seen anywhere from $700 to $1000

Thank you Denco7..that was exactly the information that I needed......I am a Tilt owner...so unlike the previous moron who posted he could have saved that shizznick for someone who cares...

Also one more thing Denco7...do you know if I could swap the Radio on that phone for the one on another HTC Touch Device thats domestic? Now If you don't know this answer..I can understand me going to the TouchHD Forum for this answer...I just thought i'd prick your head real quick...

As denco7 stated, you'll have 2G network speeds but you won't get 3G. Unfortunately, that's a hardware limitation. Something that changing the radio cannot fix.

This is the 2G Indian Diamond, not the 3G model.

If it is on Airtel, then it HAS to be 2G. Do not misguide people here and on ebay

guys i just wanna confirm 1 thing.i've a Diamond which was locked with Airtel.on the box (also on Device Info) the specs showed that proccy was MSM7206A,but after i unlocked & flashed it with cooked rom now it shows MSM7201A in Device Info.
which 1 is correct?

Moreover, it does not have the front camera. So it is 2G.

We're talking about HTC Touch Diamond here, and it's 3G models have front camera. All other models are irrelevant here.
What's important is, why don't clarify whether the one you mentioned is 3G or not?
Edit: Oh, so I see you've edited the original post and now say it is a 2G model.
What made you change your mind?

well i personally didnt thought that not having a camera means its 2g. i still think it should be 3g but when so many people r saying its 2g den maybe they are right.

when the fone was locked with Airtel and running stock firmware CPU was shown as 7206A under Settings>System>Device Information>Hardware.
but after i unlocked the fone & flashed it with cooked rom its now showing 7201A under Settings>System>Device Information>Hardware.
so which 1 is true.
also afaik MSM7206A = MSM7201A - 3G chip.is this true?

Yes, MSM7206A = MSM7201A - 3G chip.
See the specifications of the Indian Diamond here:
http://www.htc.com/in/product/touchdiamond/specification.html
Enter the bootloader (Hold Volume Down key+Reset). If it says DIAM140 64M there, it is the 2G Indian Diamond.

^^^ in Bootloader mode it shows DIAM140 64M.
that means i'm stuck with a 2G Diamond.

i think the only proper way to confirm this wud be if any1 in Delhi tries a 3G sim in the Indian Diamond.

i too feel it 2.6". why do they write 2.8 then?

Guys,
No need to worry about 7206A or DIAM140 chipset....I got answer from HTC, this is also a 3G model, but it doesn't have capability of video conferencing..I have mail confirmation (below) from HTC.

"In this regard, we would like to inform you that HTC Touch Diamond is not a 3G device. If you want to purchase a 3G device you may go for HTC Diamond2"
This sounds more like he is trying to push you to buy their Diamond 2
but on a serious note, India Diamond for Airtel is not a 3G, its only a 2G. The main feature of 3G is to have a video call which India Diamond does not have.
but Enjoy Diamond as its an awesome phone!
