Changing the frequency of the HTC Desire? - Desire Q&A, Help & Troubleshooting

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.

The radio frequencies are handled by the cpu and cannot be changed

Desire Frequency in use?

Apologies if this is a stupid question;
Can I find out what frequency the Desire is using at any time? ie which 850/900/2100 band?
Just replaced an 850/2100 Desire with a UK-originated 900/2100 and the speedtest results have almost doubled.
Just want to see if it is still using the 2100mhz network or somehow it's using a 900mhz band with better results
Sidenote: in Australia we have 850mhz desires
Does anybody have any solution on finding out which frequency the Desire is using at a given time?
Thank you

The 850Mhz is only for Telstra. If you with any other provider (3, Vodafone, Optus) you should get the EU version! If you use telstra one with let say 3 card in it, you will only get 3G when you have access to 2100Mhz network.
My Desire is telstra one and im with telstra, speed test results are better comparing to HTC Hero on 3. Im getting around 500-1000kbps better results.
Only problem is that Melbourne server is gone from speedtest.net, and now we testing connection to Canbera and Adelaide so results will be diffrent.

I live in Mexico and have a European Desire and want to change to 850 since Telcel (cel provider) is what uses.
Any help on how I can achieve this?
wrong problem explained
What I meant was for the 3G 850 band
You have to buy a new phone! The A8181 Desire does not support that frequency - you need an A8183 Desire.

Dave

Thanks for the answer dave, I was hoping there were some software tweaks.

I know I'm dredging up an old thread, but I searched and have not found a way to display which of the 3G frequency bands is being used at any given moment by my Desire. Does anyone know of an app that does this? I would be surprised if there is not an android app that does this, since it seems there are such apps for other platforms.

850MHz and 900MHz 3G, hardware or software?

It's always been my understanding that it's in the chip. But can someone confirm this for me? I'm using WCDMA 1900MHz atm and the operator sucks. There's another that offers 3G but it's on 850 which my desire doesn't support (only EDGE.) I'm quite frustrated.

It's hardware I'm afraid.
The 900 mhz model is the A8181 and the 850 mhz model is the A8183.
Belated thanks for clarification.

How do you know it's hardware? Is there some place you can check which frequency it's operating on?

check the specs for the different models.
it is DEFINATELY hardware.
think about it - if it was software, why wouldn't HTC just produce one model?
very few carriers run 850mhz 3g, so think of the A8183 as a 'special' build.

Well, actually, if YOU think about it: if they make one model, would they be able to charge an additional premium for it?

[Q] Can Not get my Desire HD to connect to 3G

Hi. I recently got a Desire HD. I am in Caracas, connected to Movistar-Venezuela and can not obtain a 3G connection.
I had an HTC Fuze/Touch Pro before, with the same SIM card and had no problem connecting to 3G, and if I put the SIM card back in the Touch Pro it connects with no problem.
I have:
Android 2.2
Baseband version
12.28b.60.140eU_26.03.02.26_M
Kernel
2.6.32.21-g66cfb7a
Build
1.32.707.5
I have tried everything in the standard Settings. Am I missing something?
... sorry if this problem has been posted and resolved before, but I am having trouble searching for "3G" as it seems to be too short for a search term.
Correct me if I'm wrong
Correct me if I'm wrong anyone, but the Desire HD doesn't support all 3G bands, only a few. So that may be why you are experiencing the problem.

That's correct most DHD models support 3G only 900 / 2100 MHz bands, unless stated otherwise in which case it'd be on the 850 / 1900 MHz range.
Chech with your telco as to which band their 3G runs on.

"unless stated otherwise" would mean that the option for the 850 / 1900 MHz exists?
Is it a radio issue? If that were the case, where could I download that radio? or would somebody know if HTC was planning to release one for all bands?

DHD's can only do one of the pairs and it's a hardware thing, don't think radio can switch between them. It's something to look out for when purchasing a new handset.
Not sure why HTC decided to go with this method, given that iPhones (and other phones) are quadband.

Just factory reset your phone. I've had this problem once and nothign worked until I did a reset of the phone.
Same problem here. You may need a different flavour of the phone.
Thanks everybody for your help.
You have been all very helpful.
Though I have to admit I am a little sad. DHD with no 3G connectivity is like a Ferrari on a dirt road...

[Q] Desire HD Radio - UMTS Frequencies

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

HTC DesireHD radio questions

Hello,
I currently use a HTC Desire HD handset, so far everything has been awesome.. One problem is that the network provider I am using (Vodafone Australia) is pretty much hopeless. The alternative is to go with Telstra, however they use different HSPA frequencies to those that my handset supports.
Vodafone Australi - 900/2100
Telstra Next-G - 850
I have a few questions which I've been unable to categorically answer from other posts.
1) is it possible to flash alternative firmware for the radio?
2) is there firmware which supports Quad Band HSPA for HTC handsets?
3) What is the actual radio chipset used in the Desire and Desire HD?
I travel a fair bit around the world, the normal Australian vodafone frequencies work well in the EU and many parts of Asia, however If I do go with a Telstra frequency then I loose the roaming, hence the question about Quad Band HSPA/UMTS.
Regards,
Jimmy.
tha'ts a really good question, i want to know about that too.. and btw, who uses 850mhz frequency? wtf... =oP
Radio frequencies are hard coded into the cpu chipset, and thus cannot be changed by flashing a new radio
