Is it possible with a custom flashed radio to make the T-Mobile US HD2 compatible with AT&T data frequencies?
yes u can u have to get the device unlocked once done u can gooogle the info from xda or simple ask att for there data info u need to manully enter

Thanks for the reply! Okay...so I call AT&T and they give me the data info. What do I do with it? Is it something where they tell you how to change it?

NO, you cannot access the AT&T high speed network with a T-Mobile HD2. The frequencies are different, and it is a matter of hardware, not software or firmware. It is built into the device.
If you install a radio from AT&T or a Non-US HD2 it will brick the phone.
The other responder is saying that if you unlock your phone you can use it with AT&T, which is true - but only at EDGE network speeds.

I am not sure if they are called tbe same thing in Windows Mobile as Andriod but what member MartyLK is referring to is called APN settings in Andriod. These are the settings that tell the phone how to access the carriers network.

Member stevedebi is totally correct here you will only get GPRS and Edge. Hec is also correct if you flash a radio be it just a radio flash or a rom that flashes another radio along with the rom. If it is not compatible with the T-Mobile US HD2 then you will brick youre HD2. Once bricked you may or may not be able to save your HD2 with JTAG. Just making sure you are informed. Also you might want to go read member samsamuel's response to this question, click here and read post number two.
Edite: Go to this thread "Unlocked HTC HD2 AT&T MediaNET/MMS Settings". This is a thread on how to get your HD2 up and running on the AT&T network. It is not a thread on how to unlock hour HD2 to use with other carriers.
There is an Australian cellular company called "Telus" that has the same radio frequencies as AT&T and can run full 3g signals. They sold the HD2 but unfortunately they are very hard to find these days now that the phone is no longer a hot seller.
I don't really know a lot about SIM related stuff, so I apologize...
Can the Rezound be SIM unlocked for US networks? The only thread I've found on another site says no but I think the repliers were referring to bootloader unlocking, not SIM. I am S-Off if that matters..just don't want to spend money on those sites that use IMEI to unlock, then get nowhere.

You don't need to SIM unlock it. Just put a different SIM in it and it'll work.
In the US? Because I've tried and never gotten anywhere...

I read elsewhere that the sim had to be activated on a prepaid phone first. Not sure of that is correct but something to look into.

Just to be sure about the specifics.
HTC rezound on the leaked 4.03.605.2 ruu
You put in a T-Mobile sim card in the rezound
And you had voice calling, texting, mms, and data working?
You didn't need to modify anything in the phone, change settings, add a T-Mobile apn, root, or Rom the phone?
It will be nice if you will write a short "how to" for moving a rezound onto USA T-Mobile.
Also were there any frequency mode restrictions?
Data speed was good?
Thanks,
Howard
Thanks guys...will keep messing with it.
Verizon would not give me an unlock code because according to them the phone isn't capable yet.
Rezound is globally capable and works on other US carriers

The FCC ruling that Verizon is responding to by making the Rezound, Razr, Droid 4, etc. globally capable also opens the phones up for use by other carriers. This was "Big Red's" initial impetus for not unlocking the phones native features. So yes, you can use this phone on Tmobile's network.

Have you tried to enter T-Mobile's APN?
It won't save and show in the list.
It appears Verizon locked it to only use Verizon's APN?
when booted into the bootloader there is a simlock item on the menu.
if one has s-off and an appropriate config.dat file on the removable microSD card it is supposed to SIMM unlock, so one doesn't get that sim locked picture on the phone after inserting another vendor's SIMM card.
this information is from reading, not from doing it.
I'm running T-Mobile US (EDGE) just fine. 100%
Did nothing but put the simcard in the phone and flashed a GSM ROM (Downtown).
I did flash the latest radio and firmware with S-OFF but everything was working before hand.
I activated the Prepaid Simcard on T-Mobiles website and used the Rezounds IMEI without problems just added the right APN for MMS and DATA.

Sounds like you have no idea if it works with stock 4.93.605.2
You know it works with "downtown" rom

Stock 605.2 ... Yes besides the annoying "invalid simcard" on the lockscreen it worked fine. Only reason I switched was because I'm not a fan of Sense 3.6

Thanks Tachi,
I plan to order a T-Mobile SIM card to play with on monday. it will have 10 minutes of talk time, but no data. I still have quite some time left on my Verizon contract before I switch to T-Mobile. This might also be a good option for my daughter.
First, I will see how this works on my stock rooted 4.03.605.2 system with htcdev unlock and s-off. If I get the SIM locked warning, I will try installing a hboot loadable SIM unlock config.dat file I got from a website - it has my IMEI inside it.
I don't know why, but I can not enter the T-Mobile apn in my system, even if I switch the phone into gsm mode.
Then I will try the downtown ROM, if it is ok to load it ontop of 4.03.605.2
thanks,
Howard
So my ultimate goal is to buy a used HTC One for use on AT&T network. And for some weird reason, all the used HTC One's in my area are T-Mobile and AT&T ones are hard to come by. For me to use a T-Mobile HTC One on AT&T's network, I understand that I need to gain S-OFF and change the CID (correct me if I'm wrong). So I was wondering unlike T-Mobile HTC One M8's (where only some phones can be S-OFFed), is it possible to obtain S-OFF on all T-Mobile M7 phones using Rumrunner method (or any other method) ?
Another question I have is looking at the network specs, I think I should be able to use T-Mobile's variant on AT&T network with full capabilities (4G LTE, 3G, 2G, etc, etc). Please let me know if that is indeed possible.
EDIT: Ignore my last question about whether AT&T network will work on T-Mobile's HTC One. I found the answer to that, by doing some searching in the forums
Appreciate all your thoughts and suggestions. Thanks!!

It has nothing to do with being S-OFF To use a T-Mobile HTC One on AT&T, you need to have the phone SIM Unlocked. This is completely different from being bootloader unlocked or S-OFF. You can try to get T-Mobile to give you the SIM Unlock code, or you can purchase a code from different resources online. When you get that code, you put in the AT&T SIM, the phone will pop up with a dialog where you enter the unlock code, and you're done. The phone will now work on AT&T. You'd just need to enter the AT&T APN information in the settings.
Now, if you want to flash it with the AT&T stock ROM, then yes, you'd need to S-OFF and unlock the bootloader, but that is only necessary if you don't want to run the T-Mobile ROM (they're both the same save for the carrier-specific apps).

Thanks Fuzi0719! Appreciate your reply. Now the reason I ask if S-OFF is possible or not is because, T-Mobile will unlock it only if you have their service for 40 odd days. Also, I really don't want to pay for any unlock services (guess being a college student makes me a cheapskate ). So my third option would then be S-OFFing right ? That's why I wanted to make sure all T-Mobile M7's can be S-OFFed (unlike the M8's where only some phones can be S-OFFed using Firewater method).

You're still not understanding the difference between S-OFF and SIM Unlock. Just because your phone gets S-OFF does NOT make it SIM Unlocked. You might be S-OFF but it will still be SIM locked to T-Mobile. SIM Unlocking and S-OFF are completely different things, one does not affect the other. If you want to use the T-Mobile phone on AT&T, it MUST BE SIM Unlocked, whether by T-Mobile or from getting the code from somewhere else. There is no way around that.
If you are not a customer of T-Mobile, but you purchased a T-Mobile phone, they will provide you the unlock code for free as long as the phone is not reported stolen or was sold while still owed money to T-Mobile. T-Mobile will look at the IMEI number and if it is "in the clear", they will give you the unlock code.
EDIT: Just to clarify, even if you S-OFF, change the CID to the AT&T model, and use the AT&T RUU to flash the firmware and system to the AT&T ROM, if you do not get the SIM Unlock code, the phone will still not work with the AT&T SIM. There is no way around that but to get the unlock code from either T-Mobile or another service. I got my unlock code from unlockcode247.com for the huge price of $3.70. If you can't afford to shell out less than $4 for the code, you can't afford a smartphone, especially at the prices AT&T charges for service.
I'm sorry if this has been asked before, and if so i haven't been able to find it. This may seem like a stupid question, but I'm still pretty new to unlocking and rooting, ect. Now my question is, since the Sprint Galaxy S5 already has gsm network capabilities, why wouldn't it be possible to just download a different radio, and install that to unlock it for domestic gsm networks? I am asking because i have a Sprint S5 that i would like to use with T-mobile.
It might be that way if such an universal radio existed. But it doesn't. So moot point.
Interestingly, the S5 hardware is almost certainly capable of operating on all GSM and LTE bands. But artificial firmware limitations restrict your handset to only the frequencies that Sprint uses, plus a bare minimum of the most popular roaming bands.
Moreover, the Sprint version of the S5 is arguably the most restrictive variant. It simply isn't going to work on most TMB bands. You might find a NV hack to add a single AWS band. But in practical terms it won't work well on TMB.
Samsung and carriers structure it this way deliberately to discourge you from changing carriers. And to make it more likely that you need to buy a new phone if you do.
.
Ok, I was really mainly just curious, like I said I am new to this kind of thing, thanks for your response. I guess I will just wait to see if someone manages to domestically unlock it and post it, and then Ill give it a shot and see how well it works. I mainly use wifi at home for anything with the internet and downloads, I just need to get it to work for calls and texts.

It used to be that easy. Things have become quite more difficult with secured bootloaders and verification checks. I think a lot of the international unlock voodoo lies in the NV items for Sprint devices. Unlocking it domestically can be done almost the exact same way as the L720 HOWEVER you will ONLY be domestically unlocked AFTER you internationally unlock it. If you domestic unlock first you'll have wasted your time.

First of all, I'm not sure if this is better suited for the M8 section or a more general section, so if it should be moved, please do so mods.
A while ago I gave my HTC One M8 running LeeDroid to my dad, who has been using it on FreedomPop. The other day, he took it in to an AT&T corporate store to switch it over to them, but they were unable to get it to work. They tested the SIM they were using in another phone and it worked there, but his phone wouldn't activate. The guy told him it could be because AT&T has started blocking rooted phones from activation, though that sounds a bit unlikely, and I'm not seeing anything about it, so I don't think that's the issue. I should also mention before I gave it to him I was using it on AT&T, until the USB port broke so I got a new phone, after which I fixed the port and gave it to him.
I'm thinking one of two things is happening: they still have the phone in their system from before and that's preventing it from being reactivated (though AFAIK that shouldn't be an issue), or FreedomPop has it locked to them, but I'm not even sure they can do that with a GSM phone since I would think the lock would be on the SIM card, not the phone. Are either of these possible/likely, or could it be because it's rooted and AT&T has changed their policy, or is there something else going on that I'm not considering? Any ideas?
https://support.freedompop.com/app/answers/detail/a_id/3308/
My bet is that FreedomPop has the phone locked to them.
Had to Google for FreedomPop, to see what it is. But looking at what I read (and the link provided above), they use the Sprint network, which is a CDMA network. And also it looks like a Sprint phone is mandatory for use on FreedomPop. So all this means to me, that you have the Sprint variant M8. And Sprint phones (due to their CDMA support) are difficult, if not impossible to work on AT&T. With most "GSM" phones, you just put the SIM in the device, and there really shouldn't be any "activation" needed (provided you have a working SIM). But CDMA devices are different. While the Sprint M8 is designed to use some foreign GSM SIMs when travelling abroad, getting them to work on a US GSM network (like AT&T) is difficult to impossible. The Sprint M8 is probably not even the same hardware as the AT&T version M8, although the information is somewhat contradictory on this point.
In short, I don't think your problem has anything to do with root, or it having been used on FreedomPop, per se. The problem is the hardware itself not being compatible with the AT&T network.

As mentioned, it's a GSM phone, specifically it's the AT&T branded version, and has successfully been on the AT&T network before.

Don't see where you mentioned that in your top post.
I know you posted to the AT&T M8 device section. But the notion that it is the AT&T (or any GSM version M8) contradicts the statement that the phone was used on FreedomPop. If it's a GSM version (like AT&T) it wouldn't work on a CDMA network like Sprint. And from what the info shows, Sprint is the network used by FreedomPop.
If it were the AT&T version, or any unlocked GSM version, you would be able to just put the AT&T SIM in the phone, and it would work. No "activation" is required. The SIM lock is on the phone (not the SIM), and the only way a phone could be SIM locked (after being unlocked) is by possessing the phone itself, and relocking it.
Root doesn't matter either. All my phones have been rooted, and work fine on AT&T. Again, I just put the SIM in, and it works.
Do fastboot getvar all, and post the results. Delete IMEI and serial number before posting. This will tell us conclusively what version of the phone, and may give us other clues what the problem is.
