Hello,
I have been reading about HTC Vision Radio around posts here (For both the G2 and the D-Z).
I saw that that the hardware specs for the Radio bands are different between the 2 models and that people can actually flash the Radios from both models into the G2 device (Which I own).
Considering I use an Israeli operator that has 3G network only (known that its bands are 850/2100 here), My question is - Does updating the Radio for my device is actually controlling the bands I can use with it ???
In other words, The main Radio circuit supports all bands and then the Radio Firmware locks it to use the specific band for the specific operator ? (i.e. T-Mobile) ...
I would love to know if that's true, so I definitely need to upgrade/update to a working Radio for my operator since I know right now I'm using only the 2100 Band and I'm getting real reception issues.....
Thanks in advanced,
Amir.
You're asking whether changing radios can change the bands used by the device for calling/data? If so than no it can't, flashing a different radio can't change a Tmo G2 to use at&t 3g bands etc... That's pure hardware.

Hi all,
Sorry if this sounds daft, but I have just been given the tech assult by a Telstra Australia guy.
Telstra uses a "Next G" network that used 850MHz and will state that ONLY phones bought through them will be able to fully utilise the network. Is this a firmware thing (IE, can I flash the radio rom) or a hardware thing? If I bought a device from anywhere else would I be able to utilise the speed of the "Next G" network? If not, what features would we be missing?
Cheers
Al
Frequncies is a hardware thing
some phones support that band as it's also used in usa you can check the wiki for the phone in question
if you have a quad band phone with 850 MHz, it should work ontelestra, the only features that might not work on it are features that have been cooked into the rom. Phone and generic features will work as the are standard to all hardware types.
If your phone is 3g capable, yes you will be able to use their updated 3g as the attachment to allow their network to work on your phone will be on a telstra sim card.
Most of the Roms I have tried(lots) all seem to have different radio bands available, I assume to suit the country/location of origin. My question is what Rom would be suitable for the GSM(900+1800)+UMTS(850+2100) which is what I believe to be the full Telstra spectrum. All the roms work OK but as I venture into the outback on a regular basis the NextG(UMTS850) is a must. The full Telstra spectrum is what I need to enable my best chances of reception. Without flashing roms is there a way to determine what bands/combinations are available as flashing is always a worrying process. If not can someone suggest a Rom? My reason for needing another suitable rom is due to locking limitations when another carriers sim is installed. I don't mean simlock but lockout of other providers data/sms and other services, limitation of band selection and others.
goldfinger, if I understand, are you looking at the band frequencies in phone settings and looking for a rom that has the complete Telstra combination GSM/UMTS on one line? My T8285 has Dutty's latest Holy Grail rom, but indeed there is no way to get that combination with one setting. Have you tried setting your Network type and Band Frequency to "Auto" and just let the phone find the appropriate signal strengths and settings for the area? Your phone is capable of that combination whether or not the rom has the correct combination as an option. Outside of the Telstra Rom, I haven't seen a rom with what you are looking for, or for that matter, what I would be looking for either, so I just keep it set on auto and it has never failed to get what I need.
The phone works fine on auto with most of the roms in the cities but without the full Telstra Spectrum there will always be limitations to receiving the strongest signal and as I mentioned I do a lot of fringe area driving so the NextG is important. The standard Telstra Rom Has the following band listings:
GSM(900+1800)+UMTS(2100)
GSM(1900)+UMTS(850)
GSM(900+1800+UMTS(850+2100)****
GSM(900+1800)+(UMTS(850)
The third band is the complete spectrum.
Where are the bands added in the roms?
I see what you're saying and unfortunately I don't think bands are added. It's just like you said, the roms used by the cooks are area specific because they are area specific releases by HTC. So, essentially it's out of our hands and up to HTC what band settings are included. Ideally, you would need a cooked rom using a Telstra based rom to get the frequencies you need. Now, I'm unsure if you can physically add the combination you need. Perhaps someone out there may know the answer to that. Are you still running the Telstra radio and rilphone, which if I recall I believe it was 1.10. I wish I could be more help to you.
The current Telstra Rom uses Radio 1.14.25.24 and I have also tried updating to 1.17.25.09 but this does not affect the bands at all. They appear to be rom specific as you said. Looks like I may have to learn how to dissassemble the Telstra Rom and cook my own rom with the correct bands. Hate all the telstra branding and limitations using the original rom. I think I better start reading.
Thanks for you help anyways Sean3.
is any radio version compatible with any rom, and what is the difference between at&t and international versions of the atrix. I got my mobile from the US and I am using vodafone Egypt...... does this make me an international or us
So far as I know, the radio version is independent of the rom. So you could have an international Atrix with the proper radio for your version as well as the proper kernel, and a US rom. Most roms do not touch the radio.
When people speak of different versions of the Atrix, they are referring to where the phone was purchased. The us version is slightly different than the rest of the world, and as such requires a different Kernel.
If your version is an AT&T version from the US, then you would use the us based kernel and radio.
so I am a US model...... Can I flash a radio that is not meant for at&t.... as your answer meant that I can but the last sentence in your reply says I cannot
I am shopping around for another radio as I have problems with 3G connectivity. I cannot have data connection whatever I do and I removed the apns and restored defaults and made new ones with the proper settings, turned 2g and 3g on and off and tried putting it in the flight mode and changing the settings for GSM only or GSM prl auto and all the other settings with no effect.
does the us version uses different frequency I checked my operator and found that they are using UMTS 2100 MHz
do you have any ideas............ I ran out of them

before flashing the radio did you make sure your apn is set up properlY?
yes I did and used 2 sim cards from 2 different operators working with the same apn settings flawlessly on other phones (blackberry torch and htc touch diamond 2)
I think, thought I may be incorrect, that you need to stick with the at&t radio if your on the at&t phone? Maybe someone who knows more than me can chime in?
I was just meaning that the radio is a separate thing from the ROM that you have on the phone.
The atrix supports 2100 mhz, so I suspect if you are having problems that it is connected to your APN settings.
When you are in the APN menu, did you try resetting to default before adding your APN? I usually have to do that on mine before I can get data to work properly.
Does anyone know if the Verizon Trophy will do CDMA on AWS with the correct PRL on any of the available radio software?
Also is there a app or a way to show cdma call info such as channel, PN, rssi?

It says "HSPA:AWS 2100" and that is the GSM Trophy. I think its safe to assume that the Verizon model supports it as well + CDMA.. but.. well.. AWS is new one on me. I won't pretend to fully understand what your talking about. XD *haha* I better go do some reading.

AWS is advanced wireless services. It's the FCC name for the band of spectrum the 1700 and 2100mhz range.
What I'm not really sure about is if the same radio is used for both CDMA and HSPA. The phone can do AWS if using HSPA, but it uses the cellular and PCS bands for CDMA. (800 and 1900mhz)
The issue is that the radio need to be programmed for those bands and there is hardware needed to make it happen. So a phone programmed for 800mhz can't just switch to 2100mhz unless there is hardware present.
The Verizon version of the phone might just have an extra radio thrown into the case that operates seperatly from the GSM one. If that is the case then it wouldn't be possible to use CDMA on that frequency. If it's all tied into the same radio then it seems like it could be done in software. In either case I'm not sure if will ever happen because you'd probably need to write your own firmware to do so. (It really wouldn't make sense for HTC to waste time seeing if the phone would do CDMA on 2100 if it wasn't designed to)
For reference there is a great article covering the bands here:
http://www.phonescoop.com/articles/article.php?a=99
There is also the full version of the spectrum chart online here: http://www.ntia.doc.gov/files/ntia/publications/2003-allochrt.pdf
There is a dev screen you can get to on the phone to show signal strength and a few other options. If you dial ##634# you can select field trial. You can see Channel #, band class, Active Set Pilot PN, Rx Signal Strengh, Rx Power (dbm) under the EVDO screen. There is also a section for 1x and GPS. I'm not sure if another option shows up for HSPA if the phone is on GSM...
EDIT: The best I can tell is that AWS uses UMTS/WCDMA so the phone should support that. HSPDA is just a faster version of WCDMA so since the phone can do HSPDA on 2100mhz it would be able to slow down to WCDMA speeds. The only time I could see it possibly being an issue is if CDMA was being used on 2100mhz and not UMTS.
Only thing I am seeing inside of the newest Verizon Trophy software (mango v3 8107) is that they added support for CMAS.
Code:
[HKEY_LOCAL_MACHINE\Software\Microsoft\ShortMsg\Settings]
"CmasOperatorEnabled"=dword:1
[HKEY_CURRENT_USER\Software\Microsoft\ShortMsg\Settings]
"CMASAlertOption"=dword:1
[HKEY_CURRENT_USER\Software\Microsoft\SMS\Broadcast]
"TestPort"=dword:4370
As for radio, there is only one radio software.. but from what I can tell, the CPU/radio has all the same support as the Trophy GSM, but with the added CDMA. AWS should work, but only via GSM bands.
hi
i have here few PCS of S5630L
its same phone but bands are not the same.
HSDPA 7.2 850/1900MHz
anyone think it can be changed via software ? or its a hardware issue ?
if so can i change bands filters ?
thx
anything ? anyone ?
it can never be done,
it is the internal radio which transmits and receives frequencies,
which is a hardware thing,
if i got you correctly S530L is CDMA and you want a GSM band

This model is not cdma, irs gsm model fits to some countries like brazil and argentina.
so this phone works only on quad gsm 2g network with no, but on 3g networks it works only on 850/1900 and i need 2100
On older nokia phones we changed anttena duplexer and bands filters and it did the job.
On newer phone like i9000 we can change bands via programing menu.
I just wonder if it can be done even with hardware changes.
Thanks
Anyone ??
I tried *#*#197328640#*#* but not working
