Cooking 2 Radio ROMs Into 1? - Touch Diamond, MDA Compact IV ROM Development

Hi All,
Sorry if this has been asked before but i searched and i couldn't find an answer. I was wondering since after the Tytn II HTC always manufacture different phones with different Radio Roms to for USA and Europe/Asia (respectively), can't someone cook a rom that actually has both radios? Is that even possible?
That would be great if we can have 1 ROM which is truely Quad band, GSM/Edge 850/900/1900/2100 and HSDPA 850/900/1900/2100.
Or is there a ROM that actually has that? I looked at the Radio ROM thread, it has many Quad Band ROMs but doesn't mention if it's GSM and HSDPA or just GSM.
Thanks for your help and sorry again if the question was asked before.

its already gsm and hsdpa...?
at least i think so...because if you're not using hsdpa(3g) you get gsm right?

Well i live in the States and have the European version of the diamond with the stock ROM, i get GSM but not 3G. I didn't try flashing any of the other Radio Roms yet. Since there are many people here who are like me that would like to have 3G too so i thought of this idea. I have no experience what so ever with cooking ROMs so i was wondering if that's possible. I also travel a lot so it would be nice to have a 3G connection anywhere i am

Update On Us 3g!

CAN ANYONE CONFIRM THAT THEY HAVE A DIAMOND WORKING ON THE 850 3G BAND FOR ATT?
I have been told that the "DIAM130" diamond will work for the 850 3g att band but I am yet to have anyone confirm this! I really wanna get a diamond but 3g is a must for me, so please let us know ONE WAY OR THE OTHER.
Geez, double posted. When there are already several threads addressing this.

Is this guy serious? Can we just like, vote to ban him now? 2 posts in the Diamond section asking the exact same question, so here's the answer you get.
Yes, I HAVE MY DIAMOND RUNNING ON 3G ON BOTH AT&T FREQUENCIES, 850 AND 1900. It runs perfect with no issues whatsoever. So Lewi, all you have to do is buy any tri-band or quad-band Diamond and not modify it one bit, it'll work flawlessly in the United States. Go get it buddy, it's yours for the taking!
(note: for any user besides lewi, this will not work. don't waste your money.)

US 3G Diamond - What gives it 3G

I noticed an unlocked US 3G Diamond at Best Buy today. I'm sure this has been asked before, but I can't seem to find the answer.
What makes the US version work on AT&T with 3G over the imported version? I have not seen a radio upgrade that allows it yet. The handsets actually looked quite similar with the exception of the back and battery.
I'm just curious whether to pick up the new one in order to get 3G service, or is there a radio update expected?
Thanks to anyone that can shed some light on it for me.
I have a US 3G version and the freq. that at&t uses here has been enabled.

Sure, it would be the 850 and 1900 Bands. But there are Quad-Band radios available for the EU Diamond. I wonder if it's a question about the device not having specific hardware or just being able to enable those bands to work properly.
Sorry for my english
he American Diamond has quad band in GSM and only two band in HSDPA, The people here says that is a har problem not the radio, the people put the american radio (08) in European version and dont work.
The American version came with the 1340 mh battery and without the front camera. Carlos

I have a Touch Diamond I bought last week from new Egg, just like the ones from best buy. For some reason, I can pick up the 3G signal and it will hold on to it for just a second, then x..{disconnects}..then immediatly picks up Edge and then Hsdpa?
I get 25% Edge and 75% Hdspa. I guess if you read the box, it says it picks up a 3.5G internet Broadband Connection....Anything over 3.5mbps is Hsdpa.

I notcied that the US version had the 1350 mAh battery instead of the 900 mAh like the EU version. Was there any documentation on why they did this? Has anyone checked if putting the smaller battery and slimmer back on the US version causes any problems?
I also find it odd that HTC briefly listed the Diamond as a Quad-Band phone on their website, and have since changed it back to a Tri-Band phone.
I still have hope that our European Diamond will work with US 3G with somefirm ware flash or something
No, it will not.

What to do with a CDMA phone or even WCDMA?

Hi I am form New Zealand and I am thinking of getting a HTC Diamond.
Now New Zealand telecom uses the WCDMA network, and I suspect the phone will be CID locked as well.
A good friend of mine has a diamond from Germany which he has flashed several times (Radio+Roms) (he is using Vodafone in New Zealand, which is GSM)
I would like to know if I can follow the normal steps that I would do on a GSM phone on a CDMA phone. Which would be: HardSPL (e.g. Olinex 1.4)-> flash Radio or ROM.
What do I need to look out for, are there special HardSPL versions or ROMS available, or can I use any ROM or Radio?
in my defence, I really tried to find informaion here ono what to do with a CDMA phone but I couldn't find any helpful threads.
So please help me out or send me links for more information.
Thanks a lot

Although there are many APPs that can be used here on this forum for CDMA, Radio's, Roms & Hard SPL's require you to visit ....HERE
band27 is right, ppcgeeks is the best place to go for you HTC CDMA needs.
Thanks for the quick reply.
I'll check that site out.
Do you reckon it would be impossible to put a rom listed in this forum onto a CDMA phone. E.g. Shaks v4.0? Since my friend strongly recommends that and he doesn't know anything about specific CDMA ROMs. It just seems that it can be a lengthy path till you find the right ROM
How can I tell in advance whether an app will work or not?

ABSOLUTELY NOT regarding ROM's....you will brick your device. Most APPs are fine though.
GUYS!!!!!!!!!!!!!!!! U R ABOUT TO MAKE THIS GUY BRICK HIS PHONE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
using WCDMA doesnt mean that ur phone is cdma!!!!!
wcdma is a coverage by the gsm if i am not mistaken.

dude,make ur own research
dont flash anything until u talked to ur phone company n asked them if ur phn is cdma or gsm
from what i know , wcdma is a coverage of gsm.
wcdma and cdma is not the same thing or network
I am still not clear even after reading an article on wiki
http://en.wikipedia.org/wiki/WCDMA
maybe this is a better wiki
http://en.wikipedia.org/wiki/Universal_Mobile_Telecommunications_System
maybe some experts can comment on this.
@konrad.schafers, you should NOT PERFORM ANY FLASH until you are sure which category your Diamond is.

For the love of God, calling your phone provider to inquire whether your device is GSM or CDMA is not necessary.
Simply open the backing to your device and check if you have a SIM card.
SIM Card = GSM
No Sim Card = CDMA
In New Zealand Telecom has always had CDMA (no SIM), after Vodafone introduced 3G they will introduce W-CDMA (the way I see it it is a hybrid between GSM-UMTS and CDMA.
Here is the quote from Wikipedia (http://en.wikipedia.org/wiki/Telecom_New_Zealand)
On the 8 June 2007, Telecom announced a plan to build a hybrid W-CDMA/UMTS-CDMA network [14], based on the WCDMA HSPA technology, to replace its current CDMA EV-DO network. The network is planned to go online in June 2009 [15] running at 850 MHz with some 3G 2100 MHz for extra coverage in urban areas. Telstra's Next G (in Australia) and AT&T Wireless also have networks running on 850 MHz, which can cover greater geographic distances and penetrate buildings more effectively than higher frequencies. Current CDMA phones are guaranteed by Telecom to work until at least June 2012. The Telecom UMTS network is planned to have no GSM coverage, no roaming coverage for 2G phones. Foreign 850MHz (North American) and 2100MHz (European) UMTS handsets can roam to this network.
I really have to talk to someone from telecom directly. It looks like flashing either a CDMA rom or a GSM rom is dangerous

Stay on topiic here....we are not talking about other companies. We are talking about the HTC Diamond....lol
None of these devices are dual compatible. However HTC is coming up with a product that will be introduced in the 2009 lineup. Off the top of my head...don't recall.

You are right, the W-CDMA allows for CDMA devices the ability to use the 3G signals. Prior to this, CDMA devices were not 3G compatible.

Calling your provider might lead to voiding the warranty of this product. If you follow instructions as per the Wiki's and reading lots of threads, like the rest of us on this forum, your experience here will be with out a doubt, a very positive one. Millions of us flashers have crossed that line and can speak to this that although at first we were all hesitate, we are glad we did..!!
Flashing is Not for Everyone! Fear determines this....
Good Luck in what ever choices you make....If you decide to cross that line then all your Radio and ROM needs can be found over at PPCgeek.coml.........Don't forget to Hard SPL first!!
If this helps
WCDMA is base on GSM technology
CDMA was developed by Qualcomm in the United States and is the dominant network in the USA- if this helps?
Please post what Current ROM, Radio your device has.
I haven't got one yet. I was checking out the possibilities of flashing etc. They'll only launch WCDMA in June over here. Yes they are quite backwards in NZ. no full 3G by the major provider (Vodafone has had it for while).
Or even worse the broadband over here!!! You Pay per GB, around $1NZD (~55 USc) per Gigabyte (plus $50NZD base charge) and that's by far the cheapest here. Ususally they charge you something like $50NZD per month for a Gigabyte of data usage and limited bandwidth. Maximum bandwidth on which they charge you heavily is maybe 6MB if you're lucky
I used to live in germany! This is driving me mad
a bit of topic but...
Germany is one of the best places for cheap charges and bandwidth for Broadband in Europe . Nz charges base charge is similar in the UK
Seems strange as Nz was clearing money cheques (remember these) the next day back in 1976 while the UK still takes 3-5 working days.
Me personally i flashed cdma rom into gsm diamond and it didnt get broken, it just did not boot up, so i had to flash again from bootloader but no one wants to experience such a story :-D

Neophyte Question

Hey guys, I'm new here and I'm just reading about this custom ROM stuff.
Now I don't have a smartphone yet and I have verizion. I'm really considering getting an HTC Touch Diamond for $99.99, but if I got it, could I use any of the awesome ROMs on here?
I was reading something about GSM and CDMA differences and got rather confused.
Thanks guys.

Hiya Beaver,
Most the Diamond roms I have seen on here are for the GSM model which is the one useful in many parts of the world (including the U.S. with carriers like AT&T and T-mobile). Verizon and Spring use CDMA which is a different type of radio/signal and is not compatible with GSM. And so GSM and CDMA phones have different types of radios and thus require different software to run them. On some other types of phones such as the AT&T Fuze have both CDMA and GSM counterparts and I have seen software on here for both versions. I'm not sure about the Diamond though.
Maybe helpful,

Hiya Beaver,
Here's a link to the forum with stuff for the CDMA version of the Diamond, but it doesn't look like there's much there. The beauty of GSM is that lots of developers around the world contribute to the development of the software since the GSM version of the phone is pretty wide-spread (though ironically I still haven't found a stable version of WM 6.5 that I really like).

I found the website, there is another site that offers quite a bit of option for CDMA ROMS though it still doesn't come very close to what's offer here in the GSM site.
Here's the CDMA diamond site I'm talking about in case anyone here has a cdma dimaond.
http://forum.ppcgeeks.com/forumdisplay.php?f=66
It has far more option than the CDMA forums here.

Verizon TP2 on ATT?

I switched to ATT because my wife wanted an IPhone. I figured the Tilt2 was the same as the Touch Pro2 on Verzion. I knew about the stupid keyboard, but had not realized it was missing the 3.5mm headphone jack. This is a big issue since the adapter is crappy and loose and audio is very poor. I use it in the car and everytime I pick it up to change songs the audio drops out and pops...
Anyway.. The Verizon phone has a Quadband GSM radio and Dual Band CDMA.
I read many places it will work on ATT, but only on the Edge network not the 3G network. See this article: http://pocketnow.com/tech-news/verizon-wireless-cdma-touch-pro2-works-on-gsm-att-network
If i'm not mistaken ATT uses 1900mhz
The specs on the VZW TP2 say:
GSM Quad-band phone capable of global roaming (850/900/1800/1900 MHz)
CDMA dual band (1900/800 MHz)
UMTS European/Asian 3G (2100 MHz)
Does anyone know if this can be fixed to offer full 3G?
I would imagine you wouldn't want to keep the stock Verizon Rom.
Could you flash the latest energy Rom on a VZW TP2 and select ATT as your carrier?
I would also imagine flashing the latest GSM radio might be bad??
Does anyone have any thoughts on this?
I'd love to dump the stupid keyboard layout and lack of 3.5mm jack...

Verizon released a Verizon TP2 radio upgrade in their official 6.5 ROM. A cab to install that radio alone without the official rom is definitely on PPCgeeks, and I'd imagine it's floating around here somewhere too. I don't know what you mean by "the latest GSM radio", but stick to the radio upgrade Verizon offered and don't flash anything intended for a solo GSM version of the TP2.

Thats what I meant.. The solo ATT GSM Radio. I figured it would be bad. There are many warnings that say it would be bad, But until just now I have not seen the REASON it's "BAD".... Bad can be relative.
If I'm on VZW and I flash a GSM radio and loose my CDMA.. Yeah thats bad!
But If I'm taking my VZW phone to ATT and I lose my CDMA but gain 3G.. Thats not so bad.
If I just brick the device... Thats really bad.
From some other posts I just read.. I think it bricks the device..
So for now.. I'll stick with the Tilt2.
to use the the verizon tp2 on the att network you have to flash a gsm radio. its disabled because of fcc rules. you will loose cdma functionality. atts 3g network uses umts(wcdma) 1900 and the verizon tps has umts 2100 which is used everywhere except north america. you can find guides on how to convert a cdma touch pro 2 to a gsm one.
