My Desire HD works with UMTS frequency 850, which means I can only get GPRS, as my provider uses 2100 for UMTS.
I know there are other variants for the DHD that work with 2100.
My question: Is it possible somehow to hack the radio firmware to make the device work in a different frequency or did HTC actually bother with different radio hardware?
Is there a 850 MHz DHD out yet? The DHD normally has a 900/2100 MHz UMTS radio in it. So it should work. Do you have 3G enabled or is your phone on GSM only?

The radio frequencies are "hard coded" into the cpu chipset, they cannot be changed. full stop. sorry

I just stumbled across this old thread.

Is the possibility of this true?? Has anyone tried to do work on the Radio ROM to bring in Quad band? I would pay to have 850 available for my phone.
Comments?
Has anyone tried an Athena radio on the Universal ( I presume yes, still looking through the forums ). And what about the HTC Sable? They both use the same CPU and the Sable in particular has comparable ROM sizes.
Quote from one of the links:
QUALCOMM's MSM6250 chipset solution helps enable worldwide roaming for
WCDMA (UMTS) terminals. The MSM6250 system solution supports dual-mode, quad-
band GSM transceiver operations [GSM 850, GSM 900, Digital Cellular System
(DCS) 1800, and GSM 1900] and WCDMA (UMTS) transmit operations for 800 MHz,
1900 MHz and 2100 MHz.
Shouldn't the Universal therefore be able to do 850 with a change to the radio ROM? Do the HTC Sable and Athena use the same chipset?
Can anyone help us?
It would be great to have a 850 band for my SPVm5000. Hope anybody can answer your question. Seems that since this phone was only released for europe and not USA the quadband was not open
Is it possibe to change the frequency that the Desire uses?
I just got an HTC Desire but it apparently doesn't use the same frequency as my other phone did so I'm stuck on insanely slow EDGE.
I know this request may sound a little odd but I'm desperate to change it.
At the moment the frequency is: HSDPA 900 / 2100
And I need to get to: 850 / 2100
I saw that you can apperently flash "Radios", is this what is needed? What exactly would flashing a Radio do?
If anyone could help me here it would be GREATLY appreciated, I mean what's a smartphone without 3G internet?
Edit: I just realized that both Rogers and the HTC Desire share the 2100 frequency, is there any way I could enable the 3G on that frequency?
I'm not 100% certain, but I believe the frequencies are a hardware problem - otherwise you would probably see a lot more mods to enable every frequency possible
If rogers is using that 2100 frequency, your phone should be searching for 3g on that frequency, but there might not be 2100 support in your area, as they use 2 different frequencies to make it cheaper to roll out (so in a different area, phones could access the 850 but not the 2100)
Updating your radio might help a bit:
Radios can make your signal a bit stronger, depending on which one you use (the best radio varies per situation/person) So it could let your phone get a higher speed on your EDGE, or maybe find a nearby 2100 signal
Yes, flashing to a different radio version and its associated RIL (if available) can help to improve issues with things like battery life, Wi-Fi performance, and 3G/HSDPA speeds. Some radio versions may work better than others for you as they are region dependant. Give a few a try and observe how good/bad they each perform.

No. It's not possible.

I've got a 850/2100 HTC Desire. While the 850 doesn't affect me, I'd have preferred if I had the 900/2100 HTC Desire.
BTW, just to re-affirm, frequency the device operates on is hardware-based and cannot be manipulated with software/firmwares.

how can i find the frequency info on my phone?Where in settings can i retrieve this information?Thanks
Hello I live in New Zealand and we have a network here called Telecom XT which uses 3G freq: 850 & 2100 mhz.
Unfortunately all Motorola Defy sold here have their freq specified as: 3G Network: HSDPA 900 / 2100
I see in the development section there is a way to flash files to restore 3G coverage and one of the files has the 850 & 2100mhz that our Telecom XT network uses. Does this mean I can flash this file to enable those frequencies on this phone or does it mean that the Chinese versions of Defy have a different chip that supports the different frequency?
Hey,
Unless the Defy has a tri band WCDMA chip (which im pretty sure it doesn't) then you can't simply flash new radio firmware/RIL to enable frequencies.
If you want an XT compatible desire, your best bet is something from T-Mobile or more ideally Telstra Australia's NextG network, which is the same as XT. Mobicity for example sells NextG handsets which will work perfectly on XT.
If you have the 900mhz Defy i believe you are limited to Vodafone/2Degrees. Flashing these Radio/RIL fixes i think were because those with 850mhz handsets with issues running radios designed for 900mhz.
Just to confirm, Defy hardware can only do certain pairs of frequencies (e.g. as say mentioned on gsmarena.com) irrespective of what ROM is put on it ?
Is there anyway to find out (from model/serial number or other way) what hardware one has ? (for 3G frequency)
I'm pretty sure about mine, though I bought this Defy 2nd-hand and flashed it, so just wanted to be sure. (I flashed it with 900/2100 MHz ROM and it seems to work fine on T-Mobile 3G in London, UK. But wonder if there is a way to check - perhaps for another unit....)
Hi everyone,
I bought my Desire HD in europe and i have RCMix Custom ROM on it.
This smmer im going to the USA and i was wondering Is my phone going to work on all USA Mobile carriers like Verizon, AT&T and others ?
as long as your phone is unlocked, then why not!
You probably want to double check the DHDs supported frequency bands with that of the US networks.
I'm sure the HTC Inspire is the US version of the DHD that has US carrier support.
From the HTC Spec List:

The next step is for you to check the frequencies used by the US networks (I'm not doing everything for you!!!*) and compare to this list.
I know Verizon still uses 800MHz in some areas (not supported).
*@Andy, I'm nice but I'm not THAT nice!
I think I may know the answer to this, but before I throw the phone against the wall, I'll first check with you guys.
I have a Wildfire S running 2.2.3 with HTC Sense. The phone is SIM unlocked as it was bought outright, S-ON. It is the version incompatible with WCDMA 850MHz and I need it to work with WCDMA 850MHz (Australian Telstra NextG network).
Since S-OFF has not been achieved via software and for all intents and purposes the phone can't be rooted, is it possible to reflash the phone with a WCDMA 850MHz compatible ROM (I know such exists, for one Telstra branded ROM is compatible but I believe there is also a HTC debranded version)?
If yes, where would I find such ROM and where would I find instructions for that (I've downgraded HTC Desire HD before, I know I need a Goldcard). If not, thank you for your time and answer.
as far as i know, 850mhz band is hardware function. if your phone doesn't support it via hardware out of the box, no software is going to make that work on that band.

From what I've been able to gather, the pones are identical, the difference is just in the ROM and bands they've arbitrarily chosen to disable. There are other phones with similar restrictions in place and it can be fixed by software.
Thanks for posting, tho.

Stylen, if you've bought a non telstra phone, it will work work on the 2100 but not on the next g 850. Unless it has the required hardware then no amount of flashing will help.
