Does anyone know where to find the tweak cabs to enable HD2 support for AT&T HSPA? Ordered my HD2 from Expansys-USA and am wondering whether the device supports that band here too.
Thanks.
It's not possible. The Euro 3g is different from American 3g. We're stuck with Edge.
Hello,
/the UMTS bands are:
1) Physical Hardware that set and only work on those bands of hardware?
2) Band are set by the flash .rom?
For example, the euro model has UMTS of 900/2100 mhz. Could a flash change those to 1700/2100 mhz?
Thank you,
Monnie
No, it requires new hardware.

Not entirely true, it's all based on the chipset that is being used and if a particular band is available and unlocked. We've seen in the past extra bands being unlocked on a phone that originaly didn't have (supposedly) any additional bands.
The QSD8x50 platform consists of the QSD8250 (HTC Leo) which supports GSM, GPRS, EDGE, HSPA networks while the QSD8650supports CDMA2000 1X, 1xEV-DO Rel 0/A/B, GSM, GPRS, EDGE and HSPA networks. Both chipsets include:
•1 GHz CPU
•600MHz DSP
•Integrated 3G mobile broadband
•Support for Wi-Fi® and Bluetooth® connectivity
•Built-in seventh-generation gpsOne® engine with Standalone-GPS and Assisted-GPS modes
•High-definition (720p) video decode, and multiple video codec support
•High-performance 3D graphics – up to 22M triangles/sec and 133M 3D pixels/sec
•High-resolution up to WXGA (1280x720) display support
•12-megapixel camera support
•Multiple audio codecs: (AAC+, eAAC+, AMR, FR, EFR, HR, WB-AMR, G.729a, G.711, AAC stereo encode)
•Support for mobile broadcast TV (MediaFLO™, DVB-H and ISDB-T)
•Support for Windows Mobile®, Android, and a number of Linux®-based operating systems
•Qualcomm’s hybrid mode alternative solution
I personaly would like this processor, also Snapdragon: QSD8672
The single-chip, dual-CPU QSD8672™ includes most of the above features, in addition to:
•Dual CPUs, up to 1.5 GHz for faster response and processing
•Low-power 45nm process technology for higher integration and performance
•Higher-resolution WSXGA (1440 x 900) display support
•High-definition (1080p) video recording and playback
•Support for HSPA+ networks - 28 Mbps downloads and 11 Mbps uploads
•Supports CDMA2000 1X, 1xEV-DO Rel 0/A/B networks
•Improved 3D graphics - up to 80M triangles/sec and 500M+ 3D pixels/sec
What I am trying to find is what GSM, HSPA bands the 'chip' supports, hard to find...

Hello,
Not that I have any experience with phone platforms but, my logic tells me, It is all the same system boards and the bands are "set" at the factory. I can not imagine that a different system board is used for different bands.
My real question is, is there a technique to change these bands other than at the factory?
Thank you,
Monnie

They can disable/enable bands on a chip if they want too by a lot of different methods (software, not connecting pins etc.), assuming the chip is capable of using the bands. Now, not every phone chipset is capable of handing more bands than what is listed as specs by carrier, but... As I said earlier, there have been phones that were capable of using more bands than originaly listed (spec'd) and those bands were activated at a later date.
One way to keep a phone exclusive is to restrict what band it uses.
A simple example of this would be the 802.11n registry fix on HD2, all it took was a registry entry to enable it (chipset was capable, just not activated by HTC).
No HSPA on the HTC HD2? rediculous...
Hi all,
I switched from a HTC Advantage x7500 class device which is 2 years old, and it did HSPA no problem.... I saw a "H" (for HSPA) in the top menu bar icon for data connect. Now with the HD2, a newer phone from the same manufacturer, all I get it "E" (for EDGE) on the same networks. LAME.
If thats the case, and EDGE is the best we can get on this phone where hspa worked clearly before, then HTC really blew it on this and this phone is a big mess-up to put it mildly. I was going to standardize my entire workplace on this phone--but not with this crippling limitation... rediculous.
Can anyone get around this with a piece of software/registry hack? I am appalled...
What about "wait until it's released officially on your network"? Then you'll get a version that can.
There's more than chipset, rom settings etc to getting compatibility on a band. Power amps, filters, etc... which are strictly hardware defined.
Why would a manufacturer make their radios WORSE or at least LESS COMPATIBLE in a newer model than a previous flagship version and lose something so data-critical like HSPA support... makes so little sense when making unlocked phones.
Because there's not enough physical space available, because it's significantly more expensive, because the chipset doesn't support it, because you don't want parallel imports, for licensing reasons,... many possibilities.
I'm inferring you bought a phone that isn't native to your market.
Odds are that you simply bought the wrong model. I'll guess you bought a T8585 instead of a T9193 (look on the back, at the bottom you'll see a T and a NextG icon.) If 3G matters to you, sell the 8585 and buy the 9193 and you'll get the 3g you so desire.*
*Unless you're in Japan, or something

I will pose another question.
My htc pure will not go past 1.5 mbps hsdpa.
The phone comes with HSPA 7.2 ready built.
Eventhough AT&T has opened the 7.2 to be used used with
HTC Aria & Samsung Captivate which are running in speed tests beetween 3.2 mbps and 4.0 mbps. My pure refuses to work at such a speed.
My question is...
Is there a way for me to manipulate it with new configuration, or is is automatic, therefore being blocked by AT&T.
if anyone has any good advice, please write

7.2mbps is theoretical, i.e. if the Gods are having a good day and all the planets are in alignment, then maybe, just maybe, you might get 7.2Mbps*
If it is stuck at 1.5Mbps, it sounds like a limit imposed somewhere as its a bit too rounded a number to be to do with distances, angles and interference. It could be your local cellsite isn't capable?
*it'll depend on things like distance from cell and stuff like that too.
I was looking at the Nexus One teardown here. http://www.ifixit.com/Teardown/Nexus-One/1654/2
Interesting to note that the RTR6285 RF transceiver does indeed support Band 5 UMTS, which I think is AT&T, according to a cached press release here. http://74.125.153.132/search?q=cach...l+RTR6285+umts+bands&cd=1&hl=en&ct=clnk&gl=us
Note it says...
North American triple-band UMTS (bands 2, 4, 5)
Japanese triple-band UMTS (bands 1, 6, 9)
European, Chinese and rest-of-world triple-band UMTS (bands 1, 3, 8)
Also... the power amplifier SKY77336, according to this document... http://docs.google.com/viewer?url=http://www.skyworksinc.com/uploads/documents/200780E.pdf
Does support the GSM850 band. Isn't that AT&T?
So what is really preventing the Nexus One from running on AT&T? Did they just not "bother" to certify it with the FCC because T-Mobile is their launch partner?
This could mean then the radio software, or some other configuration option in the firmware simply has AT&T 3G disabled.
I'll let you guys debate this, but I can't see any hardware reason why this phone couldn't work on AT&T 3G, with proper software/hacking of course.
-James
Actually the real question is, why didn't they certify with the FCC for AT&T 3G? My only idea is that T-Mobile was the launch partner, but the hardware can do AT&T 3G technically, it's just not certified and enabled.
No reason they couldn't certify and enable it later.
And I have to say, I would have no trouble going to T-Mobile, but in Salt Lake City, AT&T coverage is far superior and so are the 3G speed tests. There are many locations my T-Mobile friends can't get make calls to save their life. I hear T-Mobile is much better in other cities.
-James
Doesn't AT&T use both 850 and 1900 for 3G? Does this phone have 1900?

Believe the transceiver and amplifier support both.
I want to get people digging around on this.
-James
Very interesting stuff.
I bet a community could get a pot together and have a prize for whomever can get the n1 working on att first, assuming it actually will work
Thanks for digging up this info, I was actually in the process of starting to research this myself for when I grew tired of living on edge.

You've already answered your own question here, GSM is not UMTS.
I'm in the smae boat btw, Telstra in Aus use 850UMTS and I know how painful it can be to have 2G access in most places.

Well technically UMTS is a GSM standard, could be the same thing. Same frequencies certainly.
I was just checking the brochure for the http://www.rfmw.com/data/BRO254-08B.pdf
No where does it make mention of UMTS, like say... T-Mobile's AWS... but it does specifically have the correct frequencies listed for both T-Mobile AWS and AT&T 3G.
I'm going to make the assumption that this indicates it works with UMTS is both bands since it doesn't mention UMTS specifically at all, yet it does work on T-Mobile AWS.
James I love you man! tell me there's a way to "jailbreak" this thing.... what kind of people do we need? someone has to be willing to help with this. Oh why oh why am i only a MBA.... I need a tech degree of some kind!
I don't think it has to do with the FCC. Though we are all in love with the nexus one... remember that google and apple are nearly HALF of the same executive board. They don't want to compete with the golden goose that keeps thier stock portfolio's up that much.
We just need to find out how to activate/change which airwaves this thing is listening too and THEN we will have the first truely unlocked machine!
subscribing to this thread for an outcome.
I've been doing more reading and it seems this isn't the first phone with hardware disabled. I haven't found anything yet on if anyone has made the change yet :+\
Here we go, the Blackstone all over again .

Well, maybe. The Blackstone has a hardware limitation for the US 3G frequencies. There have been phones in the past that had software limitations that were overcome with a hack. So if the Nexus has the hardware capabilities to do ATT 3G frequencies there is a good chance that someone will figure out how to unlock it.
uh...wow. Yeah, I'll be watching this thread.

Which phones? Do you have any links we can read so we can start looking for similar solutions?
I found this link to the Diamond on XDA which they supposedly change to 3g at&t but I have read the whole thing it's long.

I'm still looking for answers! I'm just not smart enough to "create" the answer. I have hope that a future rom will help us but not for a while. For now I'll keep researching.
P.S. my phone comes tommorrow!!!!!!!!11 I'm so excited!!!!!!!!!!!111111
The radio chip supports all the UMTS bands it but unfortunately the UMTS power amplifiers (eg. http://www.skyworksinc.com/Product.aspx?ProductID=597) are NOT in the chip. Like the G1 it probably only has amplifiers for 900/1700/2100.
The quadband power amplifier only supports GPRS/EDGE: http://www.skyworksinc.com/Product.aspx?ProductID=437
Looking at the chip diagram here (http://s2.guide-images.ifixit.com/igi/ZhrRALhPFhWyLGKC.large) the two chips next to the SKY77191 look awfully like power amplifiers as well.. if so, conveniently for 900/2100

Don't get me wrong, I wish this worked on AT&T (points at logo). Guess I'm EDGE-only until my contract expires.
Just wish all carriers would have stuck to one standard
whoever helps figure this out will definitely be getting some donations from me!! i have att and no purpose of buying a N1 without 3g...
Is it possible to get turbo 3G speeds on uni trough maybe a radio upgrade, or is the hardware limited to 384 kbps?
I think this also is related with your local cell provider
Mine is working on 3G in Europe at a decent speed

Uni lacks HSDPA, so the speed will be less than new phones....
True.
Universal was one of the first devices including 3G back in 2005
I've been trying out the t-m HD2 beast, but the call quality and t-m coverage sux. I'm thinking Imagio since I like wm6 and call quality of Verizon.
Also does it have FM radio.
...Thanks!

I agree about T Mobiles reception issue and the HTC HD2 is a beast, but I cant do the reception for a phone..... And about Imagio yes it has the FM Radio feature but you have to plug in ahead phone wire into headset jack to activate because it uses wire as antenna..
Hi all
I'm currently using the Radio Version 2.10.50.28_2
I'm haven't had any problems with it whatsoever, but I was wondering if that is the best radio in terms of signal quality available for my location
I'm in London and my operator is o2 and do get pretty decent signal, but of course if there is a better radio suited for these conditions I'd like to have it
So is 2.10.50.28_2 the one I should continue to use or should I be using a different one?
RAdio
I am ORINGE customer using AxLor V 10 the same radio and everything is really PERFECT ! ! ! London area too ! ! 3G everywhere
Have to admit the 3G network is pretty decent, getting HSDPA as well =]
Guess I am on the best Radio
Radio's are always subjective. I personally find the best radio for EU roms to be 2.09.51.03_2. Brilliant call quality and decent signal. Looking at you're signature rom, you appear to be on a Tmous rom so in order to see that extra ram you'll need to stick to 2.**.50 radio's.
i am on vodafone uk and in a constant GPRS signal area. only time i get 3G+ is when i visit my girlfriend in lincoln then its constant.
my radio is 2.10.50.19_2. I use the Artimis V14 so the extra is not enabled tho i have tried other version 2.10 radios and get worse battery life.
With this one my phone is good for 1.5 days use. and thats with normal usage, net, text, calls to mrs etc.
i did condition the battery mind.
