Since this model isn't out yet, I suppose this is not yet considered a n00b question. I am, and I'm sure many of you are also, wondering if the international One XL and the US version One X on AT&T would be able to interchange radios via RUU updates. If radios are interchangeable by themselves, is it simply a matter of S-OFF?
Why am I asking this?
I'm on T-Mobile right now, planning to use AT&T model with TMo's HSPA+, but then I am moving to Europe in a few months - in Germany, they're using LTE on 2600 MHz whilst UK is rumoured to be using LTE on 1800 MHz (though LTE there is now up in the air again).
Safe!

ATT bands:
LTE CAT3 - DL 100 /UL 50
LTE: 700/AWS
WCDMA: 2100/1900/AWS/850
EDGE: 850/900/1800/1900
International bands:
HSPA/WCDMA:
Europe/Asia: 850/900/1900//2100 MHz
GSM/GPRS/EDGE:
850/900/1800/1900 MHz
ATT lite band is 700/AWS. That will not work in England or Germany if you have stated the bands correctly. Both versions will work on 3G & 2G in either market.
Band compatibility is set in hardware, and cannot be changed by flashing a new radio, if that is what you are suggesting. So if you need a particular LTE band, the phone you buy needs to be compatible with that band when you buy it.
Thanks for quick responses, everyone.
If I buy the AT&T one but I'm on T-Mobile's (bulls*** fake 4G) HSPA+ which runs on AWS 1700/2100, I imagine that would work still? Or when it mentions 1700/2100 that is segregated for downlink and uplink? If that is so, then dammit, I will have to re-evalute my life!

I see. I brought up the question about radios because, as you probably already know - since it was on XDA headlines and that, TMo's SGS2 and ATT's Skyrocket + Galaxy Note were able to switch radios. Specifically, the Skyrocket was able to flash SGS2 HSPA+ radio and fully utilise its speeds.

SGS2 & Skyrocket: http://www.gsmarena.com/compare.php3?idPhone1=4129&idPhone2=4303
SGS2 & GNote: http://www.gsmarena.com/compare.php3?idPhone1=4129&idPhone2=4374
The comparison of the Intl XL and X AT&T is making me assume that HSPA+ will work on T-Mo at least, since it supports both AWS 1700 and 1200. I guess the Intl XL only supports 2100, which continues to leave me a little confused (when comparing it to Skyrocket + TMo's HSPA+).

Safe!
You can probably flash XL and X ATT radios, but they will operate on the same bands as always.
I have a very strong feeling that the X ATT radios will be better if you are on AT&T though.

Its impossible to be 100% positive on the compatibility, since the phone is not even released yet.
But yes, the band T-Mobile uses (1700/2100) one is used for upload, and the other for download, also known as Band IV.
The 2100 band normally included on AT&T phones (for 3G international use) is Band I. So the One XL will probably not work on T-Mobs 3G network.
They have no reason to include T-Mobs band on an AT&T phone. But they do have motivation for including Band I for its international traveling customers, since this band is widely used in Europe, Asia, and other places.

Since there is no release yet, we're all speculating - which is okay.
I've been researching mobile frequencies and bands, and it seems that since there is WCDMA support listed on the specifications for frequencies: 850 / 1700 / 1900 / 2100, they fall into bands:
1 (2.1 @ DL 2110-2170, UL 1920-1980)
2 (PCS 1900 @ DL 1930-1990, UL 1850-1910)
4 (AWS @ DL 2110-2155, UL 1710-1755) could be band 10 (Extended AWS)
5 (850 MHz @ DL 869-894, UL 824-849)
The sole LTE band is:
17 (LTE700 @ DL 734-746, UL 704-716)
whilst 1700 and 2100 are also used for LTE.
DL = downlink range
UL = uplink range

The only thing that could prevent cross-compatibility (which, as mentioned, would favour AT&T) is having the LTE chipset separate from the HSDPA chipset. Though the case may not at all be for HTC, Samsung's Skyrocket (MSM8260) and Galaxy Note (MSM8660) have a single chipset that hosts LTE and HSDPA bands - thus their radios are interchangeable.
Do any of you know the specific radio chipset that is used in the One X for AT&T?
I'm assuming it's the radio on the listed SoC Qualcomm MSM8960 - which is also on the international One XL that is specified to simply host the 1800 / 2600 bands.

As I said, as this is all speculation, a development hack on the modem or straight compatibility, or non-compatibility, could be the case. I'm just going to keep my fingers crossed!
Thanks so far for all of your replies!
To contradict my previous post, HTC's website doesn't even list support for 1700 MHz for the AT&T version of the One XL.
http://www.htc.com/www/smartphones/htc-one-xl/#specs
I don't think it's possible. The chipsets between the XL and X are VASTLY different Qualcomm Snapdragon S4 vs. Nvidia Tegra 3.
The Skyrocket, AT&T LTE Note and T-Mo SGSII on the other hand all use the same Snapdragon S3 Qualcomm chipset.

I kind of have the inverse problem to this...
I'm in the UK currently, and hoping that EE's 1800MHz LTE network is given the green light for Q3/Q4 - I want a One X, but it won't be future-proof (i.e. LTE compatible), so a One XL would be great! Also I might be in the states quite a lot over the next couple of years, so it would be nice to have an AT&T LTE-ready phone.
Considering importing the One XL and using it over here - also have the benfit of S4 vs. Tegra 3...

Wouldn't be surprised to see a carrier out their own One XL variant.
I have a feeling that the One XL is international, but will require region/carrier specific versions based upon radio bands. While you can roam on HSPA+, you're going to probably be tied down to specific carriers/countries for LTE service.
Of course, development-wise this only matters for radio firmware and RILs, so development efforts won't be carrier-specific if we get S-OFF.

They're the same radio and software, but physical antennas cannot be changed. Either it has it, or it doesn't.
I am confused as I am sure a lot of others are but the HTC One XL is not the AT&T version. The AT&T version is still called the HTC One X. As shown on GSMArena and on the HTC Site. The HTC One X with Tegra(International-non LTE), The HTC One XL SnapDragon(International-LTE) and The HTC AT&T One X.

Am I the only one confused??? These are from what I am reading, 3 totally types of the HTC One X, so it should be 3 different forums, right??
sans bands, the HTC One X on AT&T and the HTC One XL International are the same device. hardware, and software wise, thus, for development purposes have been lumped into the same category.
I'm not 100% how radios work though, so we may need a separate AT&T forum for AT&T development, in the case that radios are hard wired to accept only certain bands. I assume that the radios can be attenuated to receive different signal however.
Anyone, please correct me if I'm wrong.
This will serve as the home for both the One XL (international Snapdragon S4 device) and AT&T One X. They are largely the same, although we'll need to switch out radios and such for different carriers. It should be very easy.

Your post sounds as correct as what Ive been led to believe. The only difference is the radios for the different bands, which should be easy enough to swap around. All other development should be the exact same. Even though AT&T is calling their phone the One X, its essentially the One XL.

Not only is it essentially the One XL, it is the One XL. Both have codename Evita in the bootloader.
It's like the Desire HD and Inspire 4G. You should be able to swap radios in S-OFF, but you will likely get poorer reception as AT&T will have custom tweaks on the radio files for their network, that will not be in international radio images.
Slightly confusing, it's somewhat hard to discern bands with HTC. I know i did a lot of searching to see if the HTC Raider [Rogers] had AWS so it could be used on Wind/Mobilicity. On the Box it says LTE 1700/2100 which was a toss up as to if it would also fall under AWS. After much deliberation and searching it concluded that no it did not, thus me buying the Amaze 4G, which was a sure thing.
For all these models, im going to assume Rogers is going to get the AT&T Version? Looking at the speccs am I right to assume it only has the 2100 freq and not AWS? Or am I totally off and it has full fledged AWS?.
Edit: Upon further review both bands are on there for HSDPA. Lets pray that is in the final product.
I got to play with the HTC One S prototype the other day via my stores HTC rep. It's fluid and the new camera system is just fantastic. It's ultra slim and looks great. It'd look even better in white, but all he had was a grey one.

So the One X on AT&T will have AWS and 2100mhz. AWS = 1700, which is why will all have hope it'll work in T-mobile and others that use AWS for 3/4G service.

Same thing. The One XL and AT&T One X have different supported radio bands, but they will run the same radio firmware if S-OFF. No more, no less.
Both the One XL and the AT&T One X have codename Evita, which means HTC considers both to be identical for development, and as such we should too.
Ahh, the confusion continues, if only people would read ...
Please have a look at one of my previous posts:

So, as you can see, the Rogers unit will also simply be called the ONE X, even though it's LTE, and it will operate on LTE frequencies 700/1700. Although it does not specifically state 2100 on the Rogers site, this frequency is usually used for uploading and NOT downloading. The download frequencies are often the ones that people want to see.
Peter
Addendum: I should be getting my Rogers unit (#2 on the list in Canada for their pre-orders), either tomorrow or Thursday. Rogers generally starts shipping their pre-order units 1-2 days before they officially go on sale, which appears to be this Friday, April 20.
Since they are the same hardware the modem/radio's can be swapped if we get s-off so you can effectively use the international on ATT or T-Mobile and have 32gigs vs 16 and FM tuner. The AT&T version will have support for AWS and 2100mhz. This is stated on the US HTC One X page and Gsmarena.

They are not the same as one the AT&T version is 16gigs and has no FM tuner. So, as I have stated, if it is unlocked and can get s-off we can then put the radio from the AT&T version into the unlocked international version and have 32gigs, FM Tuner and it will then work on AT&T or T-Mobile.

The link I posted from HTC Asia lists the same LTE bands for AT&T's One XL (B4=1700, B17=700). AT&T's referring to it as the "One X" and dropping the "L" also. It also mentions HSPA 2100.

From this we can say that unlocked it will work with on T-Mobile's 4G network. This is confirmed by the bands being on the phone but default.

I know for sure that:
1. Putting an HTC One XL/AT&T One X radio image onto an HTC One X will brick your phone, S-OFF or not.
2. The international unlocked variant only supports running on AT&T, T-Mobile uses AWS and so as such only EDGE will work with the international variant on T-Mobile USA.
3. Software will not magically make it possible for you to gain an LTE chipset and the associated radio hardware. Read more. Radio images are mostly pointless to change in the first place and I would strongly suggest to stay with your carrier's radio images as they will have tweaked the radio firmware to best work on their network.

This conflicts with the HTC Asia site which lists the AT&T phone's WCDMA bands as 850/1900/2100 MHz. And when you think about it, why would AT&T want to deploy a device that could so easily be used on a competitor’s network? The T-Mobile G2X was documented as being quad-band and when it shipped it wasn't. Someone needs to test the AT&T One X on T-Mobile before declaring victory. Everyone thought the same thing about the G-Note and it too used a Qualcomm chip. This is what Engadget had to say.
http://www.engadget.com/2012/02/16/psa-atandts-galaxy-note-does-not-support-aws-for-hspa/
There was a hack found but the signal is weak and it drains the battery faster than stock. So it might be possible to hack the One X if it doesn't work out-of-the-box.
http://www.engadget.com/2012/03/14/galaxy-note-gains-tmobile-hspa-access/
1. This is untrue, the chipset is the same and only radio is different so with s-off this is possible.
2. This is obvious without the radio swap as i have already stated.
3. This international One XL is already LTE capable, so not sure what you are referring too, maybe you should read up a little more. Example, T-Mobile SGS2 and ATT SkyRocket. So again, maybe read up a little more.

Lets remember, the HTC Asia site is showing the international S4 version of the One X not the AT&T version. The AT&T version is on the HTC US page AT&T branded, as i have posted by link a few times. It clearly states it will carry AWS bands. This is an HTC site so I don't think to doubt it.

Did you look at the HTC Asia link for the One XL? It specifically breaks out AT&T (by name) and Asia/Australia listing the bands for both. Since they're both official sites maintained by HTC one of them is wrong. Until the phone comes out and is in people's hands we won't know which one.
I agree, it is all nothing but speculation and it's all we can do until the phone comes out. Right now all we can do is hope and wish.
are there any roms out there that support 900mhz HSDPA?
I tried flashing the 02 modem but no luck, currently on the viper rom but it doesnt seem like there support on this either
Frequency support is hardware based. If the 900 Mhz HSPA frequency is not supported in hardware (which it should not be, since its not in the phone's specs), it can't be added by flashing any amount of software radios, ROMs etc.
actually while you are correct, but normally if 850 mhz is supported the hardware will support 900 in my experience. In fact I managed to get 900mhz, working on my at&t skyrocket so it got me thinking that it might be possible on this phone as well
Doubt it. It's entirely hardware related. Software can't change this at all.

The Skyrocket and HOX do support 850/900/1800/1900 on the 2G network, but they only support 850/1800/1900 on the 3G side. Why they do this is beyond me.
That said, I've never personally seen a provider who only has 3G on the 900mhz band. While traveling in Germany, I knew that Vodafone and T-Mobile (DE) had 3G on the 900mhz band, but they also run it on 1800mhz. If I were to wager a hypothesis, they are operating their 2G network on 900 and their 3G network on 1800, much in the same way that AT&T operates its 2G network on 850 (in some areas) and its 3G network on 1900.
Unless your provider is only operating on the 900mhz band, it shouldn't matter.

well I have 2100 as well but the point is I am wondering if there is any roms that support the 900mhz band. Doesn't 02 use 900mhz 3G?
Besides on the official website it says this! (Asia/AUS: 850/900/1900/2100 MHz)
IS the hardware on the AT&T one X the same as the one on the one XL?

Its not clear to me what version of the phone you own, and are talking about. You mention that you have an AT&T Skyrocket, but you also have Vodaphone logo by your avatar, location is stated as New Zealand, and mention O2.
If you are talking about the AT&T One X, then no, the 900 MHz band is not listed in the specs for 3G compatibility: http://www.att.com/shop/wireless/devices/htc/one-x-gray.html

I had the Skyrocket, not the OP. I was just comparing frequency specs.

Sorry, I didn't realize you had an Australian One X(L). According to the official specs, it should support 3G on the 900 mhz band. The rom you use won't make a difference. If the One X REALLY supports 3G on the 900mhz band, it should work with whatever rom/radio combo you choose. That said, there is a possibility that it is a typo on HTC's part, and that it doesn't actually support 3G on that band.

Actually, if you read post #3 the OP mentions he has an AT&T Skyrocket also.

Its really not clear what the OP has, and what the specs are. Maybe purchsed from Vodaphone in New Zealand from the logos by his avatar? Or he could have bought the phone from a 3rd party source? In any case, he seems to be pulling specs from a generic source like the HTC website, since it indicates "Asia/Aus". Its best if he got the specs from the carrier (if its a carrier purchased phone) to make sure the specs match up with the exact version you have. Even so, typos and incorrect listing have been known to happen, as mentioned.
If the band really is listed in the specs, it should be supported in software, and no changes should be needed. Is the correct APN entered?
If settings are all correct, and data is still not working, it suggests the hardware does not in fact support the band.

Some AT&T phones, including the Skyrocket, Galaxy Note, and others have been known to have some bands "hidden" - supported in hardware, but not in software. I know people have gotten the AWS band working on these phones by flashing different radios.
This has not been found to be the case with the One X, so far.

yeah I guess you are right, there are instances where it momentarily connects to 900mhz but then drops to something else. It is a AT&T htc one X that I acquired cheaply btw.
i'll probably be selling it off, a severe lack of microSD card slot is honestly a real dealbreaker
Let's say I buy an international One X. I unlock it myself. Would it accept a sim card that is for the XL and still give someone 3G?
[Not that I'm actually doing this, just curious ]

It should. Assuming the sim card slot fits the same size sim card, if not you could get an adapter if it needs to be bigger. It should work on any gsm network after unlocked
Assume you are talking about the quad core Tegra3 One X, which most people call the "international" version. Although the dual core LTE Snapdragon version has been released in so many countries in various parts of the world at this point, calling the other (quad core) version "international" is somewhat moot and confusing.
Whether you get 3G depends on what carrier you are talking about. The quad core One X has the proper 3G bands to work on AT&T (850 and 1900 MHz). But it lacks the AWS (1700/2100MHz) band that for the most part is needed to get 3G on T-Mobile (although they have been adding 1900 MHz in some cities). I know you have the AT&T logo as your carrier. But you seem to be asking a generalized/hypothetical question, so I'm giving you the most correct answer in respect to that type of question.
In general, if a smartphone has the proper 3G band compatibility with your carrier, as long as the phone is SIM-unlocked, it will work on 3G. You will likely also need to manually enter your carrier's APN info into the phone settings.
Hi
What is the difference between the original htc one x and htc with at / t
can I flash rom form oryginal htc one x to phone from at/t?
I ask because I can buy a phone from this network from US,unlocekd, but seller says that I have to
adjust MPN settings and then phone will work on another network on 3/4g.
Can I only flash with stock rom form not branded htc one x?
Thanks
First off, what is called the "One X" in most places is the quad core Tegra3 variant (code named ENDEAVORU). The AT&T is the dual core Snapdragon S4 variant with LTE (code named EVITA). Its really a completely different device internally. Flashing a ROM for the ENDEAVORU will not work on an EVITA, and may also brick the device.
You can flash any EVITA ROM on the AT&T version.
As far as network frequency support, you need to be more specific as to your location, carrier, and (if you know) the frequencies you are looking for. The AT&T version of the One X is compatible with 3G (HSPA) bands 850, 1900 and 2100 MHz. If the phone is unlocked, it should work on your home network, if your carrier uses one of these bands (you may also need to obtain your carrier's APN information, and manually enter it into the phone for 3G to work). If you carrier does NOT use one of these bands, the device won't work on 3G.
The AT&T One X works with LTE Band 17. I don't believe this is commonly used on other countries, so I would not expect LTE to work (but might, if your network uses LTE Band 17).

Thanks, it will not work on my network.
Thanks again
