If the htc EVO 4G LTE has same hardware and software as htc one xl then y aren't any of the owners of one xl complaining about their 4g? It just doesn't make sense to me y we are all having this problem...

Because the radio is different. At least that's what i'm guessing. Different network different radio.

I thought the EVO used gsm radio for the 4G LTE.. I read somewhere that the phone has an embedded sim card for gsm radio.. That's y I seen the gsm radio frequency on the menu *#*#4636#*#* and if that's the case we shouldn't have this problem... Maybe I miss understood but ill look for the article..

Whatever you read or think is 100% wrong. The Evo is on Sprint's network which is CDMA. While there may be some GSM elements reported in the phone, it is indeed a CDMA phone. Completely different networks, as any google search would show you.

Now I know sprint uses cdma for their regular services... But for the lte services they need to use the gsm in my understanding...

Sprint LTE does not use GSM.

LTE is a variant of utms/gsm. The phone itself is not gsm, there is no way to use the phone on gsm networks. You can't even use LTE on other networks because they all have their own frequencies and differences in their networks

Thank u sir... Somebody that actually answers the question instead of insulting... So with it using a variant of utms/gsm the radios are still different I'm guessing? The only thing I don't understand is I thought the radio was built with the qualcomm chip so if the phones had the same chip then the radio would be similar? Sorry if I'm wrong just trying to grasp an understanding...
Sent from my EVO using xda app-developers app
Similar board design with a soc but its a modular design that allows for custom built hardware. You can have 3 OEMs with 5 different phones each with the same Qualcomm board and soc and they could all be built specifically for one carrier only. GSM is the standard, CDMA is more prevalent in the US.

Got a question, if I got a euro EVO 3d then if i root and flash a different radio will it pick up different signals to better support it here in the USA or am I just stuck on edge??. If not is there any software adjustments that can be made to make it pick up at least 3g??

You cant software modify it to get AT&T 3G. You need a X515A model number (Rogers) EVO 3D. No way around it.

BTW, anyone with a rogers evo 3d care to send an stock rom or nandroid backup? My seller shipped me the evo 3d with a custom rom, that failed. Really would like stock back.
I've been trying to Google this and got no results. All the youtubers I asked and all the Google searches I did and I got the same result. The cdma e3d is for the USA and gsm is for the rest of the world...ARRRR! I ALREADY KNOW THAT!
So can someone please explain the internal differences between the cdma and gsm 3d and why can't gsm users flash cdma Roms (if the radio remains untouched). I'm sure I'm not the only 1 wondering why the cdma EVO 3s gets so many more roms than gsm users.
Please don't flame at me if this question has been asked elsewhere.

I was also searching for this and already found out that its kernel related because it has some other drivers and stuff running to maintain the cdma network.
Theres kernel and framework differences. Even if you were to extract a gsm kernel, and put it into a cdma.rom, it still wouldn't work properly. I've looked at the frameworks for both phones, and there was a lot more differences in the code than I had previously anticipated.
The reason there are more cdma roms, is simply because there are more devs/chefs/tweakers that use/have cdma phones.
Also many old & new developers for the CDMA EVO 3D came from the EVO 4G, which had a huge following on the same carrier.
It was like a migration of birds.

Ah, that explains it. I was wondering why there is so much more development going on for the CDMA E3D than the GSM, seeing as how Sprint is the only carrier using the CDMA. Stupid, multiple standards!

I stand by my comment about stupid multiple standards. Get with the rest of the world, U.S. carriers! Stop being different just for the sake of being different.
Now, not knowing anything at all about ROM cooking, will it ever be possible that ROMs for the E3D may be able to support both CDMA and GSM, or is there no way to code that kind of logic?

Well kinda. It's not hard to write the ROM for the gsm EVO if you made a ROM for the cdma 1. But It's hard because It's gonna require testing on a device which the cdma dev does not have.

I think the difference is the network. If you're going to Sprint then you should reference the CDMA thread.

Sprint and Verizon use CDMA. Tmo and ATT use GSM.
For the EVO 3D GSM, those are mainly all international carriers in Canada, Europe, Eastern Europe, Australia, etc.

Another big difference between the two are that the roms have completely rom components and radios. The CDMA version is strapped with WiMax 4g and the GSM version as LTE which is compatible with AT&T an T-Mobile
Can this be done? I haven't seen a thread on the topic yet. If so how can it be done.

That is a gsm phone capability, Evo3D is CDMA, the only way you can talk and surf is with wifi turned on and connected
Or connect in 4G. That's how I do it 4g+call
Sent From My 3rd Dimension
You all are correct. You cannot use voice and data at the same time. The reason GSM phones can do this is because data and voice are done on separate radios. Just like with Sprint (or any other cdma carrier) you can use LTE/WiMax simutaneously with voice, or WiFi becuase they utilize different radios. GSM phones have one radio for data and one for voice. If CDMA phones did this with voice and EVDO it would be possible as well. I do not know why GSM uses two radios and CDMA likes only one (except where LTE/WiMax are concerned).
Thanks to all that answered my question.....

Up to you I'm leaving mine turned on radio is built in to the processor so I don't think it makes to much of a difference where as with old phones they had another chip for the radios which drew more power.

This ^
There's really no point in having a separate switch for LTE unless you really just want 3G speeds only. If they drain the same power, why not have LTE?
