[Q] CDMA vs. GSM ROMs - Desire Q&A, Help & Troubleshooting

Forgive a relative noob, but are Desire GSM and Desire CDMA ROMs different? I have an Incredible but am trying to index Desire ROMs for http://www.heylisten.org/ROMs/android and don't know whether to categorize them differently. The Inc, of course, along with almost everything else, has only one version, so there's no question there, but I'm stumped on the Desire. I don't want to confuse anyone, but I don't want to force users to reflash unnecessarily. Thanks in advance for answers!

CDMA and GSM are different types of mobile networks. Because of their different way of functioning, phones need have specific hardware and drivers to be able to use the network. That said, a CDMA phone will not function using a GSM network and vice-versa. Usually, networks are GSM (all over Europe, and I don't think there is any country in the world which has only CDMA networks). The only CDMA's I know of are USA's Sprint and Verizon, though I don't know much about Asia and Canada.
The ROM's are different when it comes to the radio, and a bad radio WILL brick the device, so you should definitelly state which one are for CDMA and which for GSM (there's a chatch here: since a lot of the Disire's are GSM, you could specify all ROM's are for GSM, unless stated they're for CDMA).

Blue Angel convert to cdma network.

If I purchase a blue agel GSM PH20B. Would I be able to make it work on a cdma network like verizon in america somehow?I currently own a PH20A2 through verizon but thought about using a gsm phone on my network as well as uploading wm6 on it.If I did do this would I lose the wifi radio etc. Any help or guidance to the correct area i should be looking in greatly appreciated.
Hmm....
Well,
I'm no expert but I don't believe this is possible, we're talking about two different standards and as far as I know two different types of hardware. There's usually a similar model in CDMA for a lot of phones but I don't believe you can convert a GSM phone to CDMA.
Cheers.
No, CDMA and GSM are incompatible in hardware.
There is nothing you can do. Others have tried to get the Blue Angel IPL/SPL working on the PH20A2 (Harrier), but it complains about not being able to find the GSM radio.

Cdma Diamond Rom

Hey guys. Just wondering some things here, and can't get an answer anywhere. These same questions are posted all over the web, so please lend a helping hand.
So, there is already one CDMA Version of the Diamond released to Telus, and soon to be Verizon and Sprint. Now heres the question. If I were to buy a CDMA Diamond off the web, one that is used on Telus, can it be used for Alltel, Sprint, or Verizon?
If so, would it be possible to make a ROM to go along with these carriers? I see that there is already a Diamond Kitchen available, so what would have to be done to get one of these phones to work on these carriers? Or is it already possible?
Thanks for any help guys.
I think the rom would not help because it is hardware. Not too sure though.
u can unlock it but alot of good that will do since its cmda you have to give sprint/verizon your esn and they will have to allow your phone for use on their network and as far as i know they dont allow unlocked phones even if its the same model as one they carry since the esns have to be sprint esns. if im wrong someone feel free to correct me.
verizon said they will open their network so when that happens yes you can.
the rest no.
and telus has NOT released the diamond as of yet.
telus is launching this little cdma beauty aug 14th. my question is this:WILL THE CURRENT ROMS AVAILABLE WORK ON THIS DEVICE
sprint will let you activate any phone, they just have to load your esn into there system
You can't use a WCDMA Diamond on CDMA networks because of its hardware.
The CDMA version has got a different hardware for make it work on CDMA networks...
I think that actual ROMs for WCDMA Diamond will work on CDMA version... the software part that controls radio hardware is the Radio ROM.

Between the CDMA enabled version and this pure GSM...

Is there really much of a difference?
I'm in Canada and have been contemplating getting the TP2 from Telus for a while now, but reading up I noticed are versions that do not have CDMA/GSM bundled together?
Is one better than the other? I tried searching around but either my keywords suck or I'm blind becaue i couldnt find another thread like this. sorry if its a repeat (i'm almost sure it is..)
Which carrier branded version would you suggest I try to get (and why?).
Thanks again
if you are getting a carrier branded, just go with your carrier. all cdma versions of the tp2 have a gsm radio for international usage. if you buy a gsm version of the tp2 (ones without cdma) you can not use it on a cdma network such as telus.
I'd say the biggest difference between them, to the end user, is the absence of the 3.5mm headphone jack on the GSM exclusive versions. As The Jack of Clubs said, just get the version your carrier offers, since it's guaranteed to support all the carrier's features, like 3G bands and such.

CONFUSED need HELP

ok so i am so confused now, this is my problem: i have a sprint touch pro 2 and wanna put android on it, i am currently on t-mobile, which build do i use the GSM build or CDMA build? i installed both and still not getting my t-moble carrier signal
does sprint have sim card? If not, you should install cdma version
sprint doesnt have a sim card im have a tmobile sim car don it
You have a Sprint branded RHOD400, which is one of the CDMA Worldphone devices capable of operating on either CDMA or GSM. Because your device has both CDMA and GSM capabilities, as opposed to the GSM exclusive variants of the Rhodium, your device will be referred to as a CDMA device on this forum (despite the fact it has GSM capabilities).
Therefore, you should install the CDMA version. Though if you use Reefermattness's package, the only thing you should do differently from a GSM handset is to check the "Force CDMA" checkbox after selecting your keyboard map.
ok i redid it with the cdma version, now cant cannot to tmobile, sorry but im a real noob at this :/

How are us CDMA guys to know?

Almost all of the roms in this thread do not have info if they are CDMA or GSM. Should it not be a prerequisite to include in the description of your rom whether it is CDMA or GSM? This is making it rather difficult for me, and I'm sure others. The only way to tell as of now is to look where the author is located.

Look under CDMA.
The majority of the ROMs are GSM. You can be pretty sure that it's a GSM ROM if it doesn't explicitly say that it is a CDMA ROM.
Thank you. Is this a list of all desire roms, or only CDMA roms?
omg.. The list is of course of all(or almost all) desire roms. The cdma roms are the 5-6 ones a little down the list, listet under cdma.
Also as stated if a rom is cdma, it will be stated, as almost all roms are gsm.
If the rom title dosent say cdma, its gsm....

Ok, just use to all my old phones that had a big CDMA and GSM user base. Unfortunately I am finding out that the desire (although amazing) has little CDMA application, seems I may be fuct this generation, too sad for such a great phone!
