US Cellular HTC Desire converted to a GSM phone?

Could someone answer a novice question for me? I'm kind of confused.
Can I get an (unlocked) HTC Desire originally from Alltel or US Cellular (CDMA) and convert it to a GSM phone (for T-mobile)? If so, is rooting required?
Thanks a lot.

No, different hardware.

You would have to find a suitable CDMA antenna, and even then it probably wouldn't work properly. Carrier is differentiated, for the most part, by the phones physical antenna. That's what dictates which carriers network the phone will work with.

Thanks. I think the CDMA version does not even have a SIM slot.

G2 or DZ?

Hi, I'm a bit confused on which I have, I got it in the mail with the tmobile rom and g2 hboot fully s-offed, new, only opened to s-off, but it came from hong kong in a black htc old box, it was supposed to be a desire z, but... it has the G2 keyboard, but the dz back and "with htc sense" label.. any clue?

well other than the few things like the back cover wording and the tmobile words on the digitizer or htc or whatever, the only difference that matters is the hboot. it looks like it was a dz but know has a g2 hboot. so now it is a g2 for all that matters

Maybe it's a mix? China can make everything.

That's what I'm thinking, my biggest hope is that it has the g2 bands, because I'm using straight talk, and think I need the tmo sim

Well if you find that you have an FM radio in it, then it's DZ Hardware.
I don't know how you can tell the bands without first booting up into the phone and checking the about, but if you find it:
Desire Z - Band I: 900/2100 Mhz
G2 - Band IV: 1700/2100 Mhz
Maybe the serial number in the About Phone setting could help.
Though other sources say the G2 covers every bands TMobile uses currently:
Carrier: T-Mobile
2G Technology (Frequencies): GSM (850/900/1800/1900mhz)
3G Technology (Frequencies): HSDPA (850/900/1900/2100mhz)
4G Technology (Frequencies): HSDPA+ (1700/2100mhz)

Well battery plates are interchangeable, however it does say HTC along the top of the phone, though the keyboard appears same as my G2. I'm wondering if it's a re-furbished G2 with an DZ Digitizer and housing.
What does your hBoot say ? T-Mobile if I'm not mistaken have specific radio versions.

Here's my hboot

[Q] Tried to Connect to 3G - Couldn't Connet

Hi all,
I recently bought a new Desire HD from E-bay. Its an Unlocked AT&T phone, I'm in India and I'm right now using Tata Docomo. I couldn't able to use 3G, (2G sucks).
I searched internet and forum and found that I can enable it by "Menu - Settings - Wireless And Networks - Mobile Networks - Set Preferred Mode to WCDMA or GSM/WCDMA auto" But the problem is, There is no menu called "set preferred mode" in my phone. I tried changing all the mode in *#*#4636#*#* even after that I'm not getting 3G. My mobile is not rooted and Its using 2.3.3 Android.
Hope someone help me.
Regards,
Praveen

Unable to connect to 3G
I'm also facing the issue with 3G connection.
I checked my sim card with other mobiles with the same apn settings. It works well in other mobiles.
But in my HTC-DHD still 3G is not able to connect.
My version is 2.3.3.
I also tried updating to "Andriod Revolution DHD 7.1 ROM" also. Still the same 3G issue persist.
My mobile model shows as "A9191" which is compatible in India 3G.
Can anybody help me for identifying the problem?

Hi
Inspire 4g i.e. ATT works on different network band for 3g which is not same as the 3g network band in india. Hence you will not be able to use 3g with your handset on any of mobile providers in india.
Sent from my Inspire 4G using xda premium

That's correct. The Inspire 4G supports 850 Mhz and 1900 Mhz 3G bands, while all the network providers in India use 2100 Mhz.
AT&T Desire HD = Inspire 4G

Thanks. I was planning to get an old Inspire 4G from my friend in the US, but it doesn't seem it would be any useful now (as I am a heavy user of 3G).
however, would it be possible if I root the ROM?

Rooting will not change the network band on your mobile. I am using inspire 4g rooted but i dont get 3g on Idea so better go for some other phone which supports 3g on 2100MHz band

The frequency band support of a phone depends on it's radio, and is hard-coded into it. Radio firmware can be changed, but the radio itself is not compatible. That's the problem. So even if you root the phone (which by itself does nothing other than grant you superuser access), unlock the bootloader and flash a different radio, it still won't work. Don't get the Inspire 4G. Even on eBay, it's low price may be tempting to many, but it's not worth it if it only supports 2G.

Read the above regarding radio. The ROM might show your phone as Desire HD A9191 in Settings->About, but the phone is actually Inspire 4G. If you got it from the US, and it has AT&T on the back, then it is Inspire 4G. There is no Desire HD for the US.

hi, I have installed JT R30 by RB on my DHD but 3G is not working. checked the APN setting, but no luck. do I need to install any Radio for 3G to work? right now its 12.56.60.25U_26.10.04.03_M. plz help. it did not work with ICS by blackout. :crying:

Whether ur phone is Desire HD or inspire 4g and are u from india. If inspire 4g, then 3g won't work in India as the inspire uses different network bandwidth than present in India.

hey OP, welcome to the forums.
I would change your username as it is your googlemail account and can be used for malicious purposes.
Secondly I don;'t believe that the IG4 works in India
Third, have you tried a different ROM or a full wipe?

Inspire 4G works like a charm in India including 3G. I have used it. Please mention your carrier. Many 3G carriers are providing connectivity problems in India right now.

Airtel does not have its own 3G footprint in Gujarat, it connects to !dea cellular 3G when a subscriber attempts a connection. Try a different 3G SIM of Gujarat like !dea or Tata Docomo.

There is difference in Network
HTC Inspire 4G
HSPA+ 850/1900MHz
GSM/GPRS/EDGE 850/900/1800/1900 MHz
HTC Desire HD
Europe:
•HSPA/WCDMA: 900/2100 MHz
•GSM: 850/900/1800/1900 MHz
Asia Pacific:
•HSPA/WCDMA: 900/2100 MHz
•GSM: 850/900/1800/1900 MHz
So if you have Inspire 4g then you will not get 3g network in India.

The baseband is capable but a lot of features can be disable either by Qualcomm or HTC, hardware wise. Most likely, it is not possible. Besides, this model is exclusive to AT&T as far as I know.

It is "exclusive" to AT&T however it can be simunlocked pretty easily. Runs fine on T-Mobile 2G/3G.
I don't have T-Mobile 4G/LTE access in my area to know if it works fine on that band.

Yeah, I agree. But one of the big interests for smartphone hackers is to make the phone work or run beyond general-users' experience, like HTC HD, which can run Windows Mobile 6.5 / Windows Phone 7.X / Android / even Meego OS (Some OS may not stable, but it is fun). If One VX can work under all of the bands its chip supports, then I think it will be another amazing phone in future.

heyy, I have done bootloader unlock,s-off and root....how can I use my other carrier ship?? I put it in but requests pin..
someone help mee

there are some devices that have this kind of features blocked by software but most of them have a hardware restriction. phones like droid razr, htc rezound, samsung s3 verizon to name a few, have this restriction by software to work globaly (CDMA+GSM).
im not saying it can not be done, just unlikely (by software).
back when windows mobile 6 was still alive we saw a lot people with this kind of concerns. different models with the almost the same specifications. htc models with qwerty keyboard had tv out while non-qwerty ones had fm radio. others with the bands. this is even involves laws. the country i live the 700mhz spectrum is still being used for analog tv, hence, no other kind of devices can use that frequency.
again im not say it cannot be done at all, just unlikely.
my suggestion, search other forums of similar devices to see if anyone has tryed something like that.
