Good day guys. I need your help. I want to replace my motherboard because processor wont work properly(freezes, green screens etc.). So i want to know, is there any difference between international ver. of hd2 motherboard and T-mobile version, and could I buy T-mobile motherboard and replace it in my international hd2. If it is possible, so i want to buy this motherboard
cgi.ebay.com/HTC-HD2-Unlocked-100-Working-motherboard-only-/230603065490?pt=Cell_Phones&hash=item35b1038892
(and if you will find some analog, please let me know)
Thank you for helping.
I believe the T-Mobile motherboard/main board is slightly larger in size to the international HD2 do to the more rom space and things on the T-Mobile version. So you can probably interchange a international main board with a T-Mobile HD2n but I don't know about a T-Mobile main board in a international HD2 as the actual outer casing is smaller than the T-Mobile.
Thank you for fast answer T-Macgnolia. I was thinking about it(i mean different sizes etc) but may be it's still possible, i mean ... its probably my last chance, so if you are don't know, for sure there is someone else, who tried this and know that it works, or know for certain that it's impossible. But anyway i need to replace it, doesn't matter t-mobile or international ver. of mainboard. I just couldn't find international ver. yet. So guys if you have any links of selling this motherboard, please let me know(doesnt matter where, may be in europe too).
I've got the same problem and I've done some research on it, but I'm still not really sure whether or not the international motherboard can be replaced by the T-Mobile one.
Here's what I found out:
(quotes from another web-site)
"Memory:
T-Mobile HD2: 576MB RAM, 1GB ROM
HTC HD2: 448MB RAM, 512MB ROM
The T-Mobile HD2 has a 128MB RAM advantage over the HTC HD2 if we are talking about the stock specs. Latest developments demonstrated that the International HD2 has the same amount of physical RAM, but the additional 128MB has been hidden and thus unavailable, but unlocked via applying custom ROMs.
As far as ROM is concerned, the T-Mobile HD2 has twice as much storage memory than the international HD2, mainly because of the customizations the operator version has (not to mention the Entertainment package including Barnes & Noble eReader, Blockbuster on Demand - Blockbuster’s first-ever video download application on a smartphone, MobiTV, Gogo Inflight Internet Services - six month trial for inflight wifi services on over 2,500 daily U.S. flights and Slacker Radio)."
"Bands:
T-Mobile HD2: WCDMA/HSPA: 1700 MHz (AWS) / 2100 MHz, GSM: 850/900/1800/1900 MHz.
HTC HD2: Europe: HSPA/WCDMA: 900/2100 MHz, GSM: 850/900/1800/1900 MHz. Asia Pacific: HSPA/WCDMA: 900/2100 MHz, GSM: 850/900/1800/1900 MHz.
Main difference here is the one and only vital one: the T-Mobile HD2 supports the 1700 MHz band not supported by the International HD2. Additionally, we've posted about how to get AT&T 3G speeds with imported Telstra HD2 from Australia, which supports UMTS 850Mhz."
But still there's one thing that makes me still hope the international version can run with the T-Mobile MB: regardless the fact that the T-Mobile version is 1.5mm taller they both weight 157 grams and plus to that, I think it would be smart move to manufacture the other phone parts in such a way that they would fit both versions.
I hope I'm gonna get some answers from a couple of GSM services I've contacted lately and get back to you with the answers. Brace yourself! =]

T-Mobile is strange about sizes and custom phone cases. My previous phone was a TP2, and the T-Mobile version had a completely different case and front, for no reason that I could see except looks.
So, I got some answers. All of them conclude the fact that it's impossible to use a T-Mobile MB on an international version!
Reasons why:
- the T-Mobile motherboard is longer, so you'll have to rethink how to attach the motherboard to the housing;
- on the international version the flex cables and all the other cables are soldered to the motherboard, while on the T-Mobile version they're connected through various connectors.
Bad news, bad news...well all you can do now is hope to find a used and working motherboard, buy a phone with a broken screen or something else (those cost as much as a used MB) or sell the phone for parts...
Good luck! I'm gonna need it too ;]
Hey spnk! Thank you so much for help and your great research!
I had a thoughts like that, but still got a hope ^_^. However now the story has ended.
I've bought a new one from taobao, costs much cheaper than on ebay(ofcourse it's chinese assembled, but it says "made in taiwan" , so i dont know anything about "makers", but it's well built).
I left old, "broken" one for parts. Who knows, may be it will be usefull.
I hope that you've solved problem with your's.
Best wishes.

The HTC HD2 will not use 3g in the US. But since the phone is so fast, browsing the internet using edge is faster then with 3G on a sony X1a (my last phone).
do you already have an HD2? Regardless of anything you've read thus far, 3G is hardware dependent. No USA 3G internal radio? No USA 3G.
If you don't already have one, just wait until next month because the HD2 is supposedly coming to Telstra (who operates on 850mhz 3G, just like AT&T). HTC have said that the HD2 is coming in Q1 2010 but it's more than likely going toward T-Mo (based on leaked pics) or other carriers other than AT&T.
ah well i was under the impression that the hardware was both same for euro and us releases and just the software controlling it was different...(and how come they didnt name it the T8582 vs the T8585 as with the HD1 standard for the 2 different radios?....how they gonna distinguish the different hardware HD2s?)
come next year i may just sell mine for the new one (testra one you said). i dont suppose that tmo one will work with att 3g as its on a worldwide 3g band huh.
truly is a nice phone no doubt still
T-Mo US operates on 1700mhz AND 2100mhz for 3G (someone correct me if im wrong...one for uplink and the other for downlink). ATT can operate on 850mhz OR 1900mhz. The European version only has 900mhz and 2100mhz. As you can see, if you use the HD2 in the US (t-mo or ATT) right now, you're restricted to only EDGE unless they both possess their respective 3G bands.
this is what someone on htcforums.com said to me...confirm? deny? reject? love? i guess im just receiving conflicting info as to why this guy would believe this then?
"What you are asking about is a software differentiation. According to PDADB.net, the HD2 US version is scheduled for March 2010. http://pdadb.net/index.php?m=specs&id=2 ... us_htc_leo
The GSM version currently available is capable of T-Mobile US 3G frequencies; as T-Mo is the only US company to use WorldWide frequencies {2100MHz}. The version that is scheduled for March will be for AT&T frequencies. Since the hardware on these two versions are identical, you could flash a WorldWide version with a US version radio, & use a WW version with AT&T."
Your link doesnt work. I don't want to beat on a dead horse, but countless of T-Mo USA users have the HD2 and they could only have access to EDGE. Like I said, for T-Mo USA, their 3G has a split frequency (one for upload the other for download) that's why you need both 1700mhz and 2100mhz.
thats the link

Europe: Network Bands
* HSPA/WCDMA: 900/2100 MHz
* GSM: 850/900/1800/1900 MHz <------
Asia Pacific:
* HSPA/WCDMA: 900/2100 MHz
* GSM: 850/900/1800/1900 MHz <------
which means it can work here no? since USA att 3G is 850 or 1900?
* HSPA/WCDMA: 900/2100 MHz <--3G
* GSM: 850/900/1800/1900 MHz <-- EDGE
Your problem is that you're looking at the voice/2G/EDGE bands. The HD2 is a quadband phone, so you can pretty much use it anywhere in the world. Your original question was regarding 3G, which the HD2 does not support here in the USA (yet).
3G would be this line HSPA/WCDMA. See how it's only support 900/2100mhz?
GSM is only voice correct? .... getting my voice/data abbreviations all mixed up...

GSM is voice and EDGE (data)
For ATT the key is 850mhz 3G as that what ATT has been adding, I don't believe they are doing any new 1900 towers. You can bing it there are lot's of articles about the iPhone congestion and changing/adding 850 towers. If we are lucky Telstra an, Australian carrier, will pick up the phone soon because they use the same 850 just like ATT. This is how people got the 3G on the HD(1) to work on ATT in the united states. HTCPedia posted a Telstra HD2 rom on Dec 9th, so hopefully they are close to releasing.
Ok, so I am from California and currently living in the UK... So I have one of the T8585 models... now I know that I am going to lose my 3G connection when I go home so now I am thinking of buying one of the Telstra T9193's to work on home networks (AT&T).... but looking a bit further at the specs of the 9193 the bands for 3G are listed as 850/2100... so does this mean that if I travel back to europe with an american sim in the phone I would still be able to have 3G connectivity? If I wait for the T mobile version which I assume will be 850/1900, if I return to Europe I would have the same problem as going back home with the T8585... Seems ridiculous actually, you should be able to get a phone like this that can maintain connectivity regardless of where you travel. I remember this problem when I first moved over to the UK and had to get a Razor, just for the quad band so I could use it on both sides of the pond... Oh well, would really appreciate it if you guys had any thoughts on these assumptions and maybe shed some light

Hi !
Though the question is quite old, the answer is still interesting for anybody planning to travel or intending to buy an overseas model.
I personnaly had to resign on finding an US T-Mobile HD2 because of the 3G bands problems : our local operator decided to use 2100 MHz to cover the capital, but 900 Mhz for the rest of the island, so I was forced to stick to the European model, in order to be connected where I would need it the most, i.e. in the bush.
I could find an interesting website listing a lot of models, and able to compare them, so just have a look by yourself to this one :
http://pdadb.net/index.php?m=pdacomparer&id1=1783&id2=2062&id3=2059&id4=2192&del_id=2062
As you can see, the only differences (apart from the US T-Mobile 1024 MB ROM I'd dream to have and the 2 mm longer bottom border for the different antenna housing, given that the 576 MB RAM are actually present on all models - it's just a question of flashing the appropriate radio ROM) are the UMTS/HSDPA bands frequencies.
European HD2 (T8585) : 2100 and 900 MHz
Australian (Telstra) HD2 (T9193) : 2100 and 850 MHz
US (T-Mobile) HD2 (T9393) : 2100 and 1700 MHz
The 2100 MHz is common to all of them... Too bad a lot of operators choosed to use the other band.
P.S. : There's even another model, the AT&T HD2, featuring 1900 and 850 MHz UMTS bands, the same size as the European model (but featuring the green and red buttons), but having the 1024 MB ROM...
You're the only person to ever mention a 4th model, got a link?
In a former thread I posted the following list of HD2 I found the last two years:
1. T-Mobile US PB81120 (more memory for T-Mobile requirements and for USA specialized radio chipset)
2. European HD2 PB81100 or T8585 (specialized radio chipset for Europe)
3. Asia/Pacific (Telstra) HD2 PB81110 or T9193 (specialized radio chipset for Asia/Pacific)
4. Chinese HD2 T9188 aka Tianxi (with specialized radio chipset for China and design adjustments)
5. Dopod HD2 T8588 (identical to T8585 apart from dopod logo)
Ah I was ignoring the dopod, it was the line "there's even an at&t model" I was querying.
As for the 9188,, does that even count as a hd2? Different codename, different case, slower processor, doesn't mention hd2 anywhere in its details,,,,
Here for the US AT&T 1900/850 MHz HD2 (don't know the series number) :
http://pdadb.net/index.php?m=specs&id=2062&c=htc_hd2_us_htc_leo

You have a cooked rom installed so you will be presented with the bands from the stock rom that the rom was based on, not what the hardware is set to.

That had crossed my mind but thought it would pull band data direct from hardware.
Bit of glitch, can this band data be corrected ! is it registry based by any hopeful chance ?
could be, and im no longer on winmo and cant remember anything specific.
Id maybe fire up 'cereg editor', load up my registry and do some searches, see if anything turns up.
It doesnt really matter, the correct settings will be used, it wont affect the function of the radio.

Would like it to show correct bands just to refresh my memory of actual hardware bands when choosing options as travel a lot, although never had a connection issue abroad yet !
Will do a search on XDA & my registry & see what comes up.
---------- Post added at 04:48 PM ---------- Previous post was at 04:31 PM ----------
Found them in Registry:
HKEY_LOCAL_MACHINE\Software\OEM\PhoneSetting\BandType
Any one got the default TMOUS key value data from this path for reference ... ??
The choice between the bands may be set in the registry (band 1 / band 2 / auto), but not the frequencies, of course.
They are hardware only. Hence the different models.
So anyone got the standard TMOUS ROM & show me what options are for Bands.
I want my menu to show correct data for each option related to my TMOUS hardware not the data for the 6.5.x custom ROM donor devices hardware.
I more than realize band frequencies are not adjustable via reg keys.
Simple enough for anyone on standard TMOUS rom to look .
Thanks,
i am stay in england. i want to buy the new hd2.
thx
Do yu really want a phone that is bigger than the one you'd get locally, and won't be able to use 3G?

I agree with the lack of 3G being an issue, but I've gotta have a great big LOL at the size comment. LOL mate - funny.
I've been meaning to ask this question. So how much difference is the size? I heard it was not very noticable. I saw a link that was posted to a blog somewhere. I'm not sure how credible that source is. Is it taller or wider? By how much?
i just know the euro version is 448MB RAM + 512MB ROM but, t-mobile us is 576MB RAM + 1GB ROM.

It's 1.5mm taller - that's all (EU HD2 is 120.5mm and the HD2b is 122mm tall).

The EU version also has 576MB RAM. It's just the ROM that's different.
It is 1.5mm taller. I'm not sure that it will not work on 3G in UK: from the specs it seems that it DOES support 2100MHz UMTS (band I) so it should work in Europe. Notice that the G1 had the same specs and many users reported success when used in Europe.
In that case the European ones should have worked in the US (still talking of 3G of course), but we know they don't...

No why should they? It is very simple to understand how 3G works in different place and with different phones:
T-mobile 3G network operates on UMTS band IV (i.e. 1700 MHz upload and 2100 Mhz download).
ATT operates on UMTS bands II and V (1900 MHz and 850 MHz).
Most European networks are UMTS band I (2100 MHz) and sometimes band VIII (900 MHz).
Now, the specs of TOMUS version of HD2 says that it works BOTH on band I and band IV. That is why it can work both on US T-mobile network and in Europe. It cannot work on the ATT 3G network though.
The EU version of HD2 works on bands I and VIII so it cannot work on either of US 3G networks.

OK, hadn't seen that.
Here is the relevant part from the TMOUS HD2 specs:
Band (frequency): 850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band I (2100);UMTS: Band IV (AWS);UMTS: Band IV (1700/2100).
I'm living in US now but I'll move to Switzerland within a few months. I have ordered this phone for myself since I want to use in Europe.
Btw kilrah, maybe when I arrive in Zurich (that's where I'm going to live) I'll come and visit you
Unlocked TMOUS For Sale
I have one unlocked that I might sell if TMobile decides to charge me a restocking fee to return it. Given the demand I was thinking of selling it for $550usd.
I just recently bought a tmobile htc hd2 from ebay and plan on using it on vorgin mobile (which i believe uses bell's network).
As i understand, bell uses a HSPA+ (850 Mhz) connection, which this phone is not compatible. But i have been doing some searching and i found the phone specs on gsmarena whcih state that the american version has HSDPA 850.
I was wondering if there was any possibility that the phone will work on Virgin Mobile 3G or any way I can get it to work (unless it is just a hardware limitation)
Thanks in advance
The US T-Mo HD2 is hardware limited to different frequencies;
GSM: 850/900/1800/1900 MHz
WCDMA/HSPA: 1700 MHz (AWS) / 2100 MHz
So it should get edge no problem but 3g.....
Now the Telstra version which has the 850 band would work in theory.
So it will at least work with virgin? Because if 3 g doesn't work I could wait till later in 2010 when wind mobile expands to my area and I believe wind should work correct?

Check pdaplaza.ca
I got an HD2 from them last week. I'm on Rogers, and 3G/HSDPA work perfectly. I'm not sure about Bell.
I believe mine is an unlocked Telstra version. The T-Mobile version doesn't do 3G on 850 as far as I understand.
how much did it end up costing with shipping and all?
Hi!
I just got a HD2 here in the US. I am just visiting and my old phone, the HTC Touch HD died 2 days ago, so I bought the HD2 here.
Can you please assure me that it will work in Germany?
I think it will, because in Germany we use 900 / 1900 as GSM Frequency, as far as I know.
Can you please help? Thanks.
hi every one im thinking about buying a tmous htc hd 2 cause of the 1gb rom 576 mb ram , im just wandering if the phone will work in australia 3g , vodafone , i found out download band for voda is 2100 and upload 900
can some one shed any light on this should i buy the tmous htc hd 2 or t8585
thanks in advance
The TMOUS HD2 is actually the least useful of the three varieties to you (TMOUS, Telstra, European/international) - I use a TMOUS in New Zealand, and the gist of it is that it will work absolutely fine once unlocked, but it has a useless second 3G frequency - you'll only be able to use 2100, since the TMOUS uses 1700 as (I think) rather than the more standard 900.
The Telstra variety has 2100/850, and the European HD2 has 2100/900.
So, if you just want the extra ROM space, go for the TMOUS. But if you want better 3G coverage, it depends whether you want Voda or Telstra as a service provider.
