[Q]What is difference between Desire CDMA and GSM.Is it possible to unbrick Desire? - Desire Q&A, Help & Troubleshooting

Hi,
I'm planning to buy desire and I have few questions:
I know that Desire CDMA have not got SIM card, GSM have. But what does it mean? Like iPod and iPhone? Desire CDMA is like iPod and GSM is like iPhone?
So if I buy Desire in Poland from my Operator so I will have GSM, right?
What with bricking Desire? Is there is any way to unbrick it? Or only GSM service or HTC can do it when I pay?
I heard that installing GSM ROM on CDMA device can brick device.

CDMA is sold mainly in the US.
Follow instructions closely, don't do stupid things and you won't brick it.
However, there are methods to unbrick some things. Some can't be unbricked (corrupted HBOOT for example).
And do not install CDMA on GSM then, you'll be fine.

Every things are clear now. I can't wait to buy Desire, but I must wait when my contract with operator can be resigned.

HTC Diamond from Telus in North America - 1st provider to offer it

As it seems, as of today, Telus.ca is offering the HTC Touch Diamond on their website as a North American exclusive offer... they are the 1st one in america to offer this phone, is this true?
I ordered mine today, and will receive it in a couple of days, i know telus doesn't use SIM cards, is there a way to unlock it? Elsewhere in the world, when the Diamond isn't a SIM phone, how does it work? Can you still install any program you want, install new roms, or do whatever you want with it?
I am perplex... i wonder if i will have all control on the phone...
Thanks!
That's nothing about unlock. You won't even be able to insert a sim card.
Which means the phone can only be used in Canada, with Telus.
You will be able to do new ROM updates and all the good stuff....
but you cant unlock it because sadly Telus is CDMA
(Thats why i moved to FIDO)
Ok... so basicly, i will be able to do whatever i want with the phone, beside switching carrier is that right? I won't be able to use it elsewhere than Telus because there is no SIM card?
If this is the only thing, and i don't really bother... as long as i am able to do what i want with the phone and applications i want to install.
If I understand all of what I have read, there are no chefs cooking a CDMA ROM as of yet. Just cross your fingers that one of the talented chefs get a CDMA version of the phone so you can get their great work! But of course, you can install all the apps you want on it. It just won't be "tweaked" to its fullest.
We need a Diamond CDMA thread. When Sprint gets the Diamond, there will be loads of CDMA roms.
sprint has Diamond already. And they are CDMA. I wonder if i can unlock a Telus diamon and use it on sprint.

No, CDMA you cannot unlock, because carrier info chip works different than GSM. You gotto change hardware (I think, chip). GSM is different because of a SIM card.
I've got a Telus Diamond, and I'm starting to work with the kitchen that the guys over at ppcgeeks made. Theres quite a bit about the CDMA Diamond over there too.

CDMA Desire - Any Custom ROMs yet?

I noticed everything in this Desire section is related to the GSM Desire. Are there any custom ROMs yet for the CDMA Desire? I was to get the Clockworkmod recovery to boot from an update.zip and that appears to work ok but every Desire ROM I've tried refuses to boot.
I can't seem to find much information at all about the CDMA Desire via searching the forums or just searching on Google. From what I can tell all the hardware specifications are the same except for the radio (CDMA vs GSM). Might it be possible that current ROMs built for the GSM Desire will work for the CDMA version if a custom kernel for CDMA is compiled?
I wasn't even aware that a CDMA Desire existed!

Dave
There was an Australian desire version. That's the only I can think about.
There is supposed to be an US version, but I think it's not available yet.

I have a desire in South Korea that has a WCDMA sim card in it running on the SK Telecom network. Are we saying that android 2.2 port that the devs here created will only work on GSM desires? Also, does anyone know if I use an unlock code on my phone if it disrupt my service?
Sounds to me like you have a regular Desire because WCDMA is part of the GSM standard for 3G!
Regards,
Dave
No CDMA Desire out there. You guys already have the Incredible, the Evo and Droid X that don't work anywhere else but America and you want more still?
Like Dave says WCDMA is a different variant/name of the 3G network.
Strange that the Roms aren't working for you. The innards should be the same inside.

I have a CDMA Desire. It's a test unit for one of the smaller carriers in the states (I'm not in the states) I'm using as an internet tablet/android plaything. If you guys want to know anything about it let me know.
The CDMA Desire has launched on U.S. regional carrier U.S. Cellular. Here's a link. I'll be picking one up tomorrow.

I'll be getting one in a couple of months. I'm curious if rooting/custom roms will work normally on it.
CDMA Desire
I have heard that Mighty Mike @ Mightyrom.com is working on a Desire Rom with 2.2!
Hes on Telus but his Touch Pro 2 Roms worked on US Celular!

The Telus Touch Pro 2 is a CDMA phone and so is the USC version. So it makes sense the ROMs would be compatible.
The Telus Desire is a GSM/HSPA phone - Telus launched an HSPA network in late 2009 and they're slowly trying to make their old CDMA network irrelevant. I can almost certainly guarantee you that his Desire ROM *won't* work on a CDMA Desire.
Well that would suck!

I am pretty sure we will not see any custom roms for our desires. However, thats not all that bad. If we can just get root. Then we can uninstall what we want, tweak what we want, Install wifi teather, etc..
I still think we can be rooted in almost the same manner as the incredible. Damn near exactly the same phone.
Anyone know how to get ahold of the unrevoked team? maybe they can help. They seem to root everything.

[Q] CDMA vs. GSM ROMs

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).

[Q] HTC Desire in China

Hi all,
I've recently moved to China and taken my Desire with me. I had assumed I could just unlock it and use a chinese sim but it doesnt seem to be working. From what i've read on various sites it seems China telecom (who are my new provider) use CDMA(?) and Evo-do(?). I'm not going to pretend to understand what these terms mean.
Does anyone know if there is a rom i can flash which will allow me to use the desire on this network? Failing that I do have a chinese lenovo a68e but all of the sites i've found for it so far are in chinese so if anyone can point me in the direction of a custom rom for it (english please ) which i can use i would also be grateful but i would much prefer to get my desire working.
Any help or advice you could give is very much appreciated.
Sorry mate, I'm guessing you have a GSM device (it have a sim card in it). GSM and CDMA are two completely different technologys, they have different hardware in them, that's why CDMA users brick there phones if they flash a GSM ROM. I don't think there is a way to just change GSM into CDMA by flashing a Rom.

Thanks for the quick reply
My new phone has a sim card just like a uk one. I'll be honest and say I don't know much about any of this stuff but i've found good advice on this site and used roms and things found here before.
Are there CDMA sim cards and GSM sim cards?
It not problem in sim cards CDMA and GSM are network technologies,you have to buy CDMA phone(for example CDMA htc Desire).No ROM can help you.Here's more on CDMA and GSM.(link)
If you have a GSM device, China Mobile shall you go.
no, the difference is in hardware level, u can't do nothing
