Enable 850mhz

Hi Guys,
After alot of searching on here I was still unable to find my answer.
Im currently using XBMOD's ROM (thanks man its tops) I dont want to change from it. But the problem I am having is here in Australia im with Telstra and it uses 850mhz for its 3.5 NextG network.
I have noticed that with majority of the roms on here this is enabled or even supported. I know my phone has it because when i load it up with Telstras ROM everything works like Foxtel and and what not.
Is there someone out there that can help me get this up and running.
Then we could start mixing it in with the roms here.
thanks

is your phone the European Version?

yeah im pretty sure it is.

I'm using a Telstra diamond, and im running the official Asia 2.03 rom, and it works fine...the network drop down box doesn't show UMTS 850MHz, but it is picked up as far as i know...(i've travelled to a nextG only town and had signal - even without the patch attached installed)...also all the quad band radios support 850MHz, you can enable it in the drop down list using this patch if you want:

i installed it, but where do you enable it? which drop down list?

It's not software that allows us with Telstra Diamonds to connect to the other frequencies but hardware.
Our Telstra Diamond's are DIAM130's. They have extra hardware to enable the use of our 3G frequencies.

well i know i have the hardware cause when i am using the telstra stock rom i can do what i want to do.. so its more of a software side where i have to activate that piece of hardware

Just because you can access the Telstra features doesn't necessarily mean you're on the 850Mhz band (trust me, I learned the hard way)... you could be connecting through their 2100 Mhz network (I think it's 2100). Even if you have the option of selecting 850 Mhz in the phone settings it doesn't mean you have the hardware for it.
Want a definitive check? Try restricting the phone to the 850 Mhz setting and seeing if you can still connect. Otherwise, pull the back cover off, pull the battery away from body and read the model number below the bluetooth icon (assuming they all have this)... if it's a DIAM100 then definitely no go. If it's a DIAM130 then you're laughing and I'm not to sure on any other model no's though.
I've flashed a myriad of ROM's from here on the DIAM130 and have never had an issue with connecting to the NextG network... they have all connected straight after reboot. The only thing you have to do for internet access is ensure you set the HTTP proxy to 10.1.1.181:80 although it has worked fine for me without this.

I live in rural NSW, there is only the nextG 850MHz network here, or GSM...where i checked the signal was a nextG only region...no GSM coverage at all...so i think that's proof enough don't you?

Certainly is - but you have a Telstra Diamond and my comment was directed at luckyluke... or did I miss something ?

Agree, rip the back off and do this check first, I've found no issues in using any rom's with my DIAM130. I've left band settings to Auto lately.
I use to go in and change the registry to show all bands, but got sick of doing it everytime a rom cooker "missed" our bands.
The cab from Dutty does work I think by my memory ?
I did have a DIAM100 proir, and yes it will show "Telstra" etc but you will NOT get NextG 850.
cheers

HI
try to change registry key
HKEY_LOCAL_MACHINE\Software\HTC\AdvancedNetwork\SupportHSUPA
from 0 to 1

My device is DIAM100 and upgrade to "hTC_Asia_WWE_2.03.707.2_Radio_Signed_D iamond_52.51.25.26_1.09.25.23". It also do not have 850Mhz. Is Radio 1.09.25.23 not Quad band support? But it appear when using original ROM.

Most radios support quad band UMTS.
DiAM100 devices do NOT though and this is a hardware limitation.

Hey man, from what you get diam100 have no quad band?
mine has!

The context of 'quad' band in this thread is in relation to the Aussie Telco 'NextG' network which requires 850MHz UMTS connectivity - something you DON'T have on a DIAM100.

You meant only UMTS 850mhz or simply 850mhz (GSM & UMTS)?

We're discussing 'NextG' which is 850MHz UMTS although Telstra do have 3G service via 2100 UMTS as well...

Hey guys,
thanks for the large amount off support. I check my phone. I have a DIAM130.
And I installed duttys cab and chose GSM(1900+850)+UMTS(1900+850)
and it still isnt doing what I want it to do.
Those that have nextg here know that you get access to bigpond, and foxtel mobile tv.
But this isnt working. I think there might be something in the registery I might have to change or something for it to know that its a telstra device.

Stupid Question - Tmobile TP2 radio on ATT 3G

I'm actually a little embarrassed to even have to ask this question, I'm also pretty sure I know the answer but better safe than sorry. Can anyone confirm that the Tmobile version of the TP2 is able to access the ATT 3G network? I'm 99% sure it will but that weird Tmob band makes me nervous, any input would be appreciated.

No, it will not. However the ATT version shouldn't be too far behind the Tmo launch so don't worry too much

no offense but what is the basis for your statement, the Tmob version will have
850/900/1700/1800/1900/2100 bands which are basically the ATT bands plus 1700, why would the Wing II not work on the ATT network?

Please show me where you found this data? Tmobile USA 3g network doesn't use the 1900 band for 3g; they use the 1700 band which is why Tmobile has to have devices specifically made for their network and why the Tmobile USA version won't work on ATT USA.
Again to clarify:
Tmobile USA = 1700/2100 for upload/download for its 3G
ATT = 850/1900 for upload/download for its 3G
Now Tmobile USA does use the 1900mhz frequency but that its GSM frequency it is not related to the 3g frequency. Confusing i know, but you asked.

One of the images advertising it does state all those bands, but does not differentiate which are for gsm and which for 3G (which can be misleading and confusing, ergo the clarification by jim_0068 ^). Though if they share the 2100 I have no idea whether you can get limited functionality or if you HAVE to have both of them. *shrugs*

actually this is not entirely true either,
AT&T is using 850 and 1900 Mhz for their 3G network,
it was revealed recently that they are pushing the 3G network to the higher frequency (850) and plan to have the 3G completely on 850 by 2010.
if AT&T is using 2100, we would've been able to use the european HTC devices which has the 2100 band.

As far as I'm aware:
GSM: 850/900/1800/1900
UMTS:1700/2100
And therein lies the problem... While it supports all the bands that would be required, only a small subset actually apply to a 3G connection/signal...
Minimally, that would be the specs for it to work on T-Mobile, and quad-band GSM is just standard on 99% of phones these days...

You're correct and i edited my post it is 850/1900 for ATT US 3G

I gaurantee you that the T-Mobile Touch Pro2 will not work on ATT's 3G Network At All... the frequencies for ATT will only support the 2G Network and therefore only phone calls and text messaging will work.

let's not go that far, let's not forget gprs (same speed as dial-up) and more importantly EDGE (for some that's more than enough).

when I go into the phone settings -- band I have these options on the Tmobile TP2:
GSM (900+1800)+UMTS(900+2100)
GSM (1900+850)+UMTS(1900+850)
UMTS(2100+800)

hmm, now I think the T-Mobile Touch Pro2 works on ATT's 3G Network.
It should also work worldwide too.

oooh, European bands, "standard" North American bands (they're not really standardized, neither in the US nor Canada and Mexico is barely getting 3G into place), and no idea what the last one is for, sounds like cdma...

Obviously this is some bull**** because it supports all of the 3G frequencies of worldwide carriers and american carriers.

I think those numbers are for software only, in fact you probably don't have the hardware to support the frequencies of the wrong carrier.

seems that 800mhz is for Japan
and it doesn't allow for all of the North American bands (it's missing the 1700 one).
Could be just a software thing without hardware support, though that might be a tad odd, any way to check if it is?

My Xperia X1a shows UMTS (900) even when I check the settings... IN FACT only the X1i supports
It's very likely that the numbers you are seeing are actually all of the frequencies that are "summed up" and therefore the TP2 for T-mobile does not have the actual hardware.

Those options have been around with the custom ROMs, I have that too on my Fuze, if your hardware doesn't support it then it'll just be an eye candy.
Bottom line is this, if you want to utilize AT&T's 3G, then you'll need to wait for AT&T's Fortress because you need the 850 and 1900 band (UMTS band II). If you want to use T-mobile's 3G you still need a TP2 that has the 1700 and 2100 band (UMTS band IV), and no you cannot use european TP2 to access US T-mobile's 3G band because european's (and asia's) 3G utilizes UMTS band I, they are on a slightly different frequencies even though they are categorized both on 2100Mhz.

[Q] Is it possible to Flash G2's 3G Radio, an set it to work on 900/2100 mhz??

Well, it's just as the title of this thread says... I have a Tmobile's G2 (A.K.A. HTC Vision), which its 3g default bands are under 1700 / 2100. Here on my country, all the providers have their 3g services on 900 / 2100.... soo... Is it possible to Flash T-mobile G2's Radio, an set it to work on 3g 900/2100 mhz, so I can use the phone on 3G, instead of that annoying and extremely slow EDGE??
Or, is there a Custom ROM that has these settings on it? (I mean, a rom that automatically turns the 3g band to 900 instead of 1700)
Thanx.

No you can't, the radio bands are set in hardware (e.g. the physical antennae in the phone), not just in the radio software.

Why would you need to, the phone would use the 2100 band for it's 3G in your country? I took mine to Russia and it worked fine.

I don't think it's that simple. I only get edge on my T-mobile G2 using the Rogers network.

Rogers doesnt use 1700 or 2100 so that is to be expected. The original posters country has a 2100 3G, I would suspect he just isn't in a coverage area.

I don't think it works like that, I think it needs both bands to work. If it was that simple then surely they wouldn't bother making different phones for different markets (e.g. T-Mobile US vs Europe/Asia)

That may be...I'm only speaking of my experience in Russia, they have 2100 only 3G and mine worked without the second band.

Just to add, T-Mobile US use the 1700 MHz band for the uplink, and 2100 MHz for the downlink. So presumably the phones (i.e. G2, as opposed to the Desire Z) are physically setup like that too.

Oh I thought Rogers uses 2100. Either way, no worky.... sad.

Ah, I think I'm following you, because Russia exclusively uses 2100 for up and down my phone worked, but since his county has a seperate uplink and a downlink band it won't?

Yeah I think that's it. I don't know *that* much about this myself, just picked up on a few discussions about the G2/DZ on here over time.
Have a look at this - http://en.wikipedia.org/wiki/UMTS_frequency_bands
I think the "problem" is that the G2 uses exclusively "Band IV" for 3G (i.e. 1700/2100 split), but somewhere like the OP's Dominican Republic uses Band VIII (900).
What the OP needs is a Desire Z, which operates on Band I (2100) and Band VIII (900).
Russia appears to use Band I (2100) as well. Maybe a G2 can partially work there then ?
Rogers uses something else, Band II (1900) and Band V (850).
As I say, I'm don't know that much about this myself, so if anyone else can help clarify/confirm/deny, then that'd be great.

Much appreciated.
Sent from my HTC Vision using XDA app.

Via Google, I dug up another interesting piece of info.
Although it's not on HTC's official spec list on their site, on T-Mobile's support pages it says that the G2 does Band I as well. Which would explain how it would have worked in Russia. That's not going to help the OP's problem though.

Wow mega confusing, but you helped clear it up, thanks!!
Mine worked very well in Moscow, I was pleasantly suprised, it was kind of a bonus to be able to get on the web, I wasn't expecting much.

I don't understand why the manufactures don't provide phones with penta-band 3G support like the Nokia N8. Maximize profit when producing 2-3 same phones with different frequencies maybe? I mean quad-band GSM has been supported for pretty much all of the current phones, why not 3G bands as well?

Has anyone tried this option?
bring up the dial pad and dial
*#*#info#*#* (aka *#*#4636#*#*)
press "Phone Info"
you'll get the screen with the imei, phone no, network and a button that says "Run Ping Test" at the top
press your "menu" button
when the menu pops up, it'll have 6 options, select radio band, view sim address book, view fixed dialling numbers, view service dialling numbers, get PDP list, and More.
Choose the first one "Select Radio Band" then select the appropriate band.
Not sure if it helps in this situation, but I found it in a thread about gaining 3G in Europe on the N1

hey bro.. I read from one topic in TMo's official G2 forum that the G2 will work on a country with only a UMTS band of 2100 both for up and down (the answer is from TMo employee, an engineer)... hope you'll be enlightened. I bought an unlocked G2 and I researched extensively before purchase. Im from the Philippines which only supports the 2100 band for 3G. I Know and Im 100% positive that the phone will support the 3G band here in my country. cant wait for my G2 (arriving tomorrow)
btw... coverage is vital. if the 3G signal is weak or non-existent in your area, you'll be switched to edge for data on your phone (naturally).. good luck
sorry.. cant post the link. would've loved to have posted it.

That's the Band I thing that I was talking about, that T-Mo shows on their spec sheets (but HTC doesn't seem to list, for some reason).

I think the G2 will do 3G if any one of the two bands are supported by the country. Correct me if Im wrong

There is nowhere in the world that uses 2100 in both directions. Band 1 is 1900 UP, 2100 DOWN.
In all cases, your phone must be able to upload on the frequencies that the towers listen on, and download on the frequencies that the towers transmit on.
I.e., north america vision transmits on 1700 or 1900, receives on 2100.

[Q] Changing GSM Band Lock

Hi Guys,
Well, this is my first time posting here, so hello to you all!
Anyway, down to my problem. I have a Desire Z A7272 running on the Australian Telstra network. I just bought a new sim card today that is Next G activated.
I have a few problems which I am hoping to solve by asking you experts First of all note that the Telstra Next G network runs on the 850mHz bandwidth, which I believe my phone does not support. Seeming as I live in regional Australia, this is undesiarable because although 21000mHz is supported and available, Telstra only runs it in the metro area, where it doesn't reach me.
I was searching the net for a couple of days until I found a forum where it explained how to lock the GSM bands. I can't link it as I have lost the page. What I did was dial *#*#4643#*#* and change the network lock to "United States". This was because in the US they don't have the 900mHz band they use the 850mHz band and I was hoping to get my phone to use the 850mHz band.
Now to my 2 problems.
1. When I locked the phone to the 850mHz band, it seems that I can't access *#*#4643#*#* anymore. I type the number in, and nothing opens. I was wondering how to fix this so I could set it up to "Automatic" again.
2. I was wondering if there is anyway hardware or software wise to be able to access and use the 850mHz network. If you could link or quote some reliable/trusted sources that would be excellent. I will take unknown sources but will do with caution, I don't want to break my 2 week old phone.
Thanks guys, sorry for the essay.
Haash.
EDIT: Please note that my phone is running Android 2.3.3 with HTC Sense 2.1.

Your phone is only capable of accessing whatever bands your hardware is designed to. I don't know the specs for your Desire Z, but if the bands you want are not listed in the hardware specs, you will NEVER get them. You would need to investigate whether there is a desire z model built to run on the gsm spectrum you need.
For example, here in the US, Tmobile and AT&T phones can be unlocked to use on each other's EDGE network. But no magic code can ever give them the hardware needed to run each other's 3G network.

Thanks, now all I need to do is get my *#*#4643#*#* working again so I can change it back to the 21000mHz network that I can use.

For anyone wondering:
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
BUT, for the Tmobile G2 (American version)
GSM:
850, 900, 1800, 1900
UMTS:
1700/2100, 2100

Thanks, does anyone know how to unlock *#*#4643#*#*?

Hello community what a great help can someone found from here ... so here we go ...
My problem is i turn on my mobile data to get 4g then stay's for a while but then it dissapears and then drops down to E and it wont change from there ... and in order to bring back the 4G i need to restart the phone or to shut it down and turn it on again ...
do i need to change my rom or i need to change / flash my radio ? rom is the stock rom i think i got on it ( 5.0.1 sense 6.0 )

That doesn't tell me what band MTN uses for LTE (4G). You should call your carrier and ask them (and confirm they use 2100 MHz for 3G).

ok so frequencies are from 900 - 1800 for all speeds E up tp 4G and are using At&T Mobile

I take this to mean 900 and 1800 MHz (bands 8 and 3), rather than the way you have it typed "from 900 - 1800" which makes it sound like a range, which doesn't make any sense.
I also don't think this information is correct (as I've interpreted it), as far as I can tell, 1800 MHz (Band 3) is not used for 3G anywhere in the world: https://en.wikipedia.org/wiki/UMTS_frequency_bands#Deployments_by_region_.28UMTS-FDD.29
You need to be sure of exactly what band is used for each (2G, 3G, LTE), before we can proceed:
What band (or bands) used for 2G?
What band (or bands) used for 3G?
What band (or bands) used for LTE?
It pretty rare that the same exact band or bands are used for all 3 (2G, 3G and LTE) by one carrier, so the answer is expected to be different for each, and should be asked, and answered on an individual basis.
Reason we need to be so specific here, is that there is no radio for this phone that supports Bands 3 and 8 across 2G, 3G and LTE (and in fact, no radio that supports Band 3 for 3G).
Once you've properly determined what bands are needed, and identified what M8 version supports those bands, the way to proceed would be:
1) S-off by sunshine
Note: If sunshine temp root doesn't work, you may need to unlock bootloader and root, before you can s-off with sunshin
2) Possibly need to change phone's CID and/or MID
3) Flash the firmware or RUU which contains the desired radio baseband
Even then, its not guaranteed that LTE will work. I've see a good number of folks on these forums that properly flashed the radio baseband (or converted to another version by RUU) that supports the desired bands, but still didn't get LTE service. I don't know why this happens, and have never seen a solution. But its a distinct possibility.
But at a minimum, you should be able to get 3G working on your carrier. Which alone may make the above process worthwhile.

Hello and thank you very much for you time i will go again and ask for more direct info's about bands individual
i have found back up of a radio and i flash my phone and now i do get LTE singnal's but hardly get H and 3G when no 4G detected it goes to E ... well ....
now i got another problem maybe i shou ld post a new thread ... my gestures won't work suddenly ( omg !! ) i calibrate and uncheck and reboot and check them from setting's over and over nothing worked

You need to specify exactly what you flashed, and where you got it from, for this info be worthwhile in any way.
Also, still need to know what bands your carrier is using, in order to determine what radio to flash.
Why you are flashing radios, without knowing if its the right one (supports your carrier's bands)? This is really careless and reckless.
Is the phone s-off? That is normally the only way you can flash radios manually (aside from a signed OTA, RUU, firmware.zip). And flashing things with s-off is a great way to brick the phone, if you flash the wrong thing (and it doesn't sound like you know well enough to know right vs. wrong).
