Hello,
Evo 3D uses SQN1210 WiMax chip which supports 3 WiMax bands.
Including the one I need (3.3-3.8 GHz).
I found some ways to change frequencies in 2.3 and 2.5 GHz bands.
IE:
unzipping the PC36IMG.zip file
open system.img using a hex editor program and replace each occurence of 2647000, 2657000 and 2667000 with alternate frequencies. There are 2 or 3 occurrences of each of these 3 numbers
re-zip the files into an new version of PC36IMG.zip
complete the simple root process using this new version of PC36IMG.zip
I wonder, is it safe to try this in 3.3 GHz band?
Damn, found that this is for Evo 4G...
Anyway, is there some way to change those bands?
Even if you could change the frequencies, I'm not sure what that would do for you, as the wimax on this phone can only be used with sprint towers.
Really?
As I have the GSM model...

If you could get the frequencies to work, there may be other steps. Some people have figured out how to get off of the Sprint WiMax and onto Clearwire.
Although, if you have the EVO 3D GSM, there is no WiMax radio in it. This becomes moot.

Yep, which is why I assumed you had the CDMA model.

I understand you would like to know if Evo 3D GSM model supports Wimax beares.
I can help you with that, it does support Wimax.

Don't know where that came from, but the KDDI and Sprint Shooter variants support WiMax, however the gsm do not have a WiMax radio. Anyone who tells you different does not know what they are talking about.

Can I unlocked a thunderbolt and put my tmobile g2 sim and used it?
No. The TB doesn't use GSM as a radio and is strictly CDMA for the phone side of things. Also, the LTE radio is different than T-Mobile's 4G radio. I'm sure somebody with a more technical side of why will come in, but that's the basic reason it won't work.
the only carriers verizon phones can switch to is cricket and and sprint (if either carrier is even willing to activate the phone on the network).
T-mobile can only take unlocked GSM phones (which would mean att phones)
I don't know enough about the thunderbolt being used on different carriers cause I don't fully understand exactly what data is being stored on the sim card. If it is only 4g data than theoretically It should be able to work only on sprint/cricket (without 4g, if they are willing to activate it).

As above, no, you can't use it on T-Mobile, you could take it over to Cricket/MetroPCS. Metro I know uses 4G LTE, so you'd be able to get everything out of the phone. However, I know roaming with that provider sucks unless you don't travel anywhere.

MetroPCS uses a different frequency band for their 4G LTE (I think they're on 1700, and Verizon is on 700), so the LTE won't work.

No you cannot take it over to Cricket/MetroPCS. The phone does not have a traditional MEID to allow it to work on a traditional CDMA network, and the LTE radio is not compatible with the "LTE" system that MetroPCS runs.
GSM
If you don't know what you're talking about then don't post it. Obviously you don't have a Thunderbolt to say if it can be unlocked or not. HTC Thunderbolt uses GSM network on 4G LTE. It can be unlocked, but haven't figured it out yet.
NO CRICKET OR METROPCS can be run on it.
I took out my sim to see if the phone will work on 3G. And the result is no. No way of putting it on cricket.

LTE is not GSM. The Thunderbolt runs on 700 MHz LTE and 850/1900 CDMA. It does NOT support ANY GSM/UMTS/HSPA bands. You CANNOT take it to ANY GSM provider. If you were able to unlock it, you MIGHT be able to take it to another LTE carrier, but ONLY if that carrier also uses 700 MHz for LTE (for example, possibly AT&T once they launch LTE), but even then you'd be able to use it for data ONLY. It is unlikely that you'll be able to use it on another CDMA carrier either (such as Cricket or MetroPCS) because it isn't provisioned in the way all other CDMA phones are.
Jumping on the bandwagon, no.

The TB will NEVER work on any other carriers GSM network. Period. End Of Line. It is not a matter of "unlocking" the phones. The LTE standard does not define interoperability with existing the existing GSM standard. The TB cannot operate on a traditional CDMA network (think Cricket/MetroPCS) because it is missing fundamental components required in every CDMA handset (there is no hardware MEID on the TB). Without an MEID the device will not work on a CDMA network, no matter how much unlocking you try. It will not work because the network cannot talk to the phone and there is nothing you or anyone else can do to change that fact.
What VZW has done is create a hybrid system linking their LTE network with their CDMA network. There is a reason dialing *228 does nothing on the TB. There is nothing for the system to update. All of the settings are created on the LTE network and are pushed to the VZW CDMA network on their back end. Your phone number is tied to your SIM card on their network, not your MEID. Want to prove it to yourself, take the sim card out of your TB and put it in another TB. Care to guess what happens? I'll help. The new TB you just put your SIM card into will now have your cell phone number. Now if you have been with VZW for more then 5 seconds you would know that with every phone prior to change your number you had to call customer service and they had to update your MEID and in turn you had to update your phone (*228) so the CDMA system knew what phone belonged to what number.
Tl; dr...: LTE and GSM are not interchangeable terms and technologies. LTE radios cannot function on existing GSM networks. TB is not a true CDMA device and will not work on a traditional CDMA network.
The Atrix can't use 4G on tmobile.
Can the new roms with the unlocked bootloader change the radio frequencies to work with tmobile's network?
or
Is this a hardware problem?
No unfortunately it is a hardware limitation.

Are we sure it is hardware? The specs say qualcomm mdm6200 which via software (as per the qualcomm data sheets) is able to use umts 1700/2100 bands(ie AWS bands).
Let me grab the links.

I was reading the pin outs and that is where I determined that there are no seperate pins for AWS or well any band and so I would assume the frequency is baseband determined.
If anyone is still looking. Pages 102 through 104 is interesting as it gives the pin outs that need to be programed in software for the correct bands. If anyone knows how to break open a radio firmware or program the radio that would allow us to get all bands working I think. This would also possibly allow for targeted radios that use less energy since they only rx/TX on the frequency that is available in that location.

In our area , there is available EVO3D cdma for cheap rate, it has a T-mobile logo on it, but the buyer says tht he has unlocked it for reliance cdma network
question is if i root it and put a custom rom on it, will it still be unlocked at reliance or it will be locked ??
if it has t-mo branding on it, it's probably gonna be the sensation, which is not the evo 3d. Secondly, t-mo is gsm only. If I were you, I'd verify if it really is the 3d, not the sensation, but I'm sure it will be the latter (if it isn't some scam to begin with)

I'm fairly certain my CDMA EVO 3D will NOT ever operate on a GSM network w/o changing the radio hardware inside.
Unless the GSM version comes with both radios inside, it will be impossible for it to operate on a CDMA network. "Unlocked" is generally a GSM term as GSM devices can be unlocked and then operate on any carrier.
Where as CDMA devices have to be programmed for a specific carrier. The programming process for a CDMA device can be a bit complex for people w/o computer experience.
Hope that helps clarify! I'm sure somebody else with more knowledge on the EUR versions of the GSM EVO 3Ds can chime in from their experience.

Also very great point! Don't think there is any GSM EVO 3D version being officially sold in the US under the TMO or ATT brand (the two largest GSM companies in the US). Perhaps a foreign GSM version of the EVO 3D, once "unlocked", could operate on a US GSM carrier such as TMO or ATT, but fairly confident TMO and ATT havent ever sold a GSM EVO 3D.
As a double check, if you wanted, a quick glance at the line up of phones available on their web site should help clarify. Or if you really wanted, call their customer service departments and ask about a EVO 3D or any type of 3D device to see what they have to offer.
Since the GSM Evo 3D has a dual-mode radio and an MSM8660 processor that is capable of CDMA 2000, wouldn't it theoretically be capable of running on a CDMA network?
The PG86300 Evo 3D has an MS8660 processor, or am I mistaken?

It wouldn't be the processor that makes any difference, just the radio.
I don't have experience with it because I never have had the interest, but Google "CDMA Workshop" and supposedly you can use it to get phones to work on different networks, I.E. I've heard of Verizon phones being changed to work on Sprint. So theoretically you could get any phone with the right CDMA frequency radio to work on a given network. Not sure of the legality though... ha

Don't think the cpu will have much impact on radio operations, other than perhaps speed of the device.
If the radio works with CDMA and operates on the same frequency as the network, yes, it should work. Keep in mind, just like GSM, CDMA frequencies will vary based on carrier and country/regulation.
Would research the specific country/carrier's CDMA frequency in order to determine specifically if your device will operate correctly with it.
Good luck!
the cpu of EVO 3D gsm vertion is 8660 or 8260??
and if it is 8660, it means that EVO 3D could support 3 network types including GSM WCDMA and CDMA.
is there any one have a method to make EVO 3D gsm vertion to support CDMA???
thx

The Evo 3D is a msm8660 processor device, but the GSM version cannot work on a CDMA network due to the radio band frequency. That's in simplest form.

Here are the specifications for the GSM Evo 3D. The radios are all based on GSM technology and the phone would require different radio hardware to support CDMA.

My major is microelectronics. As i knows,the radio hardware is integrated in SOC(system on chip) which is MSM8660. is it right? if so , can we flash the radio to solve this problem?

The specs on gsmarena are mostly incomplete or sometimes wrong. The GSM evo 3d has MSM8260 chipset and CDMA has MSM8660 or is it region dependent?
Im not sure but according to some sources gsm has 8260
@OP
MSM8xxxs' are chipsets. The CPU is Scorpion.
And
No the GSM 3D does not have the hardware to support CDMA but the CDMA 3D has hardware (except sim slot, software, f/w, software radio) to support GSM.

This is correct. MSM8660 has support for HSPA+ as well as other GSM frequencies. It has no sim attached to the chipset altought there is a mount point for it. I read on another forum some time ago that a real computer genius was able to hack the 8660 to recognize GSM but that was it because without the things mnomaanw mentioned all it could do was recognize the signal.
The MSM8260 that is in the Sensation and EVO 3D GSM version have no CDMA radio at all.

PDADB.net is the best source for this kind of info I find. Here you can see the different versions of the Shooter or EVO 3D. Basically there are 2 GSM versions that use the 8260, the Sprint version uses 8660, and the KDDI version uses the 8660 as they use some CDMA in Japan I think.

Perhaps the chipset in the GSM Evo 3D varies by model or region then because the CyanogenMod table of devices also shows it as an MSM8660, but that may just be for software compatibility. The XDA specifications do reflect the MSM8260 for the GSM model.
ramjet73
Well, the only difference is CDMA, so it doesn't really matter which chip it has.
