I'm switching to Sprint soon and picking up the Evo 3D. I was going through the forums and I saw that there is a section for GSM Android Development and CDMA Android Development. What is the difference between the two?

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

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??

It all depends I'd there is a carrier lock. Might want to post this in the GSM 3D forum.

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!

But do Verizon, US Cellular, or MetroPCS offer the EVO 3D? That's what we're talking about here, the EVO 3D.

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.

Wow where is all the CDMA people at ?
The poll has really shocked me . I thought Cdma would be much much more but apparently not. now may be more devs will come to the gsm android development side .
P.s. based on the poll at the writing of this post
i would go with cdma...gsm companies here are no good..prices suck
CDMA here in the US
GSM here in OZ. I did hear a comercial on the radio saying Telstra is starting 4G roll-out, so maybe soon.
I'm actually kinda surprised at how many have the GSM version. For all that, why not just wait a few extra weeks and get the GNex which just released in Europe.
it seems that no CDMA users here cuz they are bussy rooting and s-off ing and trying new ROMs not like us GSM users we are just jumping around topics looking for something fitting our version and now we lost hope of devlopment section and we are looking for MODS in general section
CDMA here... Sprint

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.

Sprint LTE does not use GSM.

Google search for Evo 4g lte network specs:
http://lmgtfy.com/?q=htc+evo+4g+lte+network+specs
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.
Just wondering if this is Ok to do because there are some ROMs that are better/cooler on GSM/CDMA (GSM ROMs that CDMA users might want to have but that aren't available for CDMA or CDMA ROMs that GSM users wish to have that aren't available for GSM users. A build of cm 11 is already posted for the GSM HTC evo 3d and not for CDMA yet. I was thinking about flashing this ROM but wasn't sure if It will mess up on my CDMA evo 3d or be unstable. If I'm not making sense let me know. Any answers will be thanked. PS: if the major thing of flashing GSM ROMs to CDMA is only like no calling or no connection to towers or what ever, its not a problem because I use my phone on WiFi only and play games for the most part.

I wouldn't recomend you to flash GSM ROM on CDMA device. It's possible your installation procedure will stop automaticaly but there is a chance it will brick your device.
I tried once, and it screwed my recovery and didn't boot ..... Not advised:banghead:
