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.

Telstra NextG

Anyone,
I have flashed a few roms and radios, and I love my phone.
Currently on latest Radio and LeeDroid 2.0a
My question is how can I tell if I am on the 850mhz NextG network or the standard 2100mhz 3G one?
I cant find anything in the phone that gives me this info.
Thanks
Daniel

Anyone?

You'll know when the 3G indicator in the status bar shows a H... meaning HSDPA.
What is the model number of your phone?
The only handset thats compatible with Telstra's Next G band is the A8183.
EDIT:
The ROM that I run on my Desire is this one:
http://www.t-mod.org/
It's a mod based on LeeDroid, but edited with necessary Telstra settings (apn, user agent, bookmarks, etc) -- but without the bloat

Yes I know the H icon, and yes I have a NextG phone. But nextg phones can still connect on 2100 band, which Telstra supports. And it is still HSDPA. I want to know if its connecting to 3g via 850 or 2100

Sorry you're right... Telstra handsets can still use the 2100 band.
From what I've been reading, you're network operator will change to "3Telstra" while using 2100.

I understand that the Telstra SIM cards have a preference for 850, then if unavailable 2100 then GSM, but other than looking at the operator id there's no easy way to tell which 3g band you are using.
With WinMo there used to be some stuff like HTC Field Test which was an app that provided engineering data about your device where you could see the carrier id (Telstra has a different carrier id to 3Telstra), but I'm not sure whether there is an Android equivalent.

I have looked in the menus at
Dialer : *#*#4636#*#* but nothing there

Telstra's 2100 network identifies itself as "3TELSTRA" (because it is half owned by 3) and Telstra's 850 network identifies itself as "Telstra Mobile" (or some such).
You can probably see this info in the lock screen and/or by pulling down the location bar. At least that's where I see it, but I'm using a cyanogenmod ROM. You can try forcing your phone onto one or the other under the wireless settings too.

Another way to tell is the MCC+MNC value, which you can view in the app "Network Info II". NextG (850) is 50501, 3Telstra (2100) is 50506.

[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.
Sent from my HTC Vision using XDA app.

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.
Sent from my HTC Vision using XDA app.

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] LG G pro 3G issues

I have Korean LG G Pro F240L
everything works alright except that it doesn't fully use it's 3g capabilities
I live in an area where 3G signal is not that stable, usually 2-4 bars, signal can drop for a few seconds every now and then, I use telstra in Australia, which use 850Mhz/2100Mhz 3G network (850 in most areas, 2100 only for extra coverage)
I set the network preference as Auto, the trouble is that most of the time the phone sticks to 2G/GPRS with small icon on the top showing "G",
and if I want to use 3g I have to go to the network setting and change it from auto to "WCDMA only", the network will change to 3g (icon on top showing 3g) with signal strength about 2-4 bars
obviously with unstable 3g signals I can't keep it "WCDMA only" all the time, so I have to change it back to auto.
once it's in auto the phone will not revert to GPRS straightaway, it will keep going with 3g for a while and then if there is a drop of 3g signal it will then change to 2g/gprs and stay that way.
is there anyway to set the phone in "3g preferred" state where 3g is utilized automaticly whenever the internet is needed? (as far as I know, no such option exists).
do you have any trouble with your 3g settings? please share, thanks

I have discovered something new
in the hidden menu-WCDMA service menu-GSM/WCDMA band, when you click on WCDMA 1900 and WCDMA 2100, it shows success, whereas when you click on WCDMA 850 it displays fail
it seems that the phone is not using the stable 850 band at all, rather it relies on the 2100 band, this explains the erratic signal strength
I did a bit more digging
the band frequency for korean providers are
SK (S) 2G (CDMA) 800, 3G (UMTS/HSPA) 2100, 4G (LTE) 850/1800
LG U+ (L) no 2G, 3G (CDMA/EVDO)1800, 4G (LTE) 850/2100
KT (K) no 2G, 3G (UMTS/HSPA) 2100, 4G (LTE) 850/900/1800
also
telstra 2G (GSM/EDGE) 900/1800, 2G (UMTS/WCDMA/HSPA) 850 (main 99% population) /2100 (minor), 4G (LTE) 1800
AT&T (E980) 2G(GSM/GPRS/EDGE) 850/1900, 3G(UMTS/HSPA) 850/1900
strange that there doesn't seem to be direct connection/conflict between telstra bands and the LG U+ bands, i.e. if my F240L is able to use GSM and WCDMA 2100, why not WCDMA 850
I believe G pro is a global phone that supports all communication standards
I am unsure about the root of the problem, is it the matter of settings (i.e. can be solved by tweaking the service menu), or the problem of incompatible radio (hence can be solved by flashing appropriate radio)
also is there anyway to tell the band frequency the phone is using? I did my search and nothing yielded, I believe there is no such solution
my question comes down to how to enable/unlock 850 band on this phone?
If you use AT&T and have a korean phone, do you have similar problem? (as shown above AT&T partly relies on 850 band as well)
also if i guess right the problem is not limited to LG G Pro, any LG Korean phone potentially will have similar issues, I tried search optimus G forum but nothing turned up.

Same problem, korean phone wrong band

I got mine yesterday and have the same problem. Is it possible to select the band? mine is the SK version and I need to work with the AT&T band, can I just flash a new radio band? How do I get to the hidden menu?
Thanks!

I have kind of same problem with my f240
i guess if the at&t stock rom could resolve those problems
edit:
service menu:
5457#*240#
hidden menu:

no
I have since learned that basebands are all hardware encoded, at least for LG phones, and there is no way to enable WCDMA 850 band if it is not originally supported by the phone, flashing the radio will not change the hardware capability of the phone
The Korean LG G pro supports only
2G : 850/900/1800/1900 MHz
3G : 900/2100 MHz
4G, LTE: F240K - 900/1800 MHz (Band 8 & 3) F240S - 850/1800 MHz (Band 5 & 3), F240L - 850/2100 MHz (Band 5 & 1)
I have since change the network provider (who provides 3G on 2100 band), it's not ideal but it's the only solution for me
pls correct my if I am wrong

i have LU6200
inside my house 3G is suck, so i use GSM Only mode, but i only get G signal which mean GPRS i think and it is very slow. How to enable 2G/EDGE so i can get faster internet than GPRS?

Hi, I have F240k the 3G over 900 Mhz band is imposible.. I dont know if my phone is broken or I need flash with any new Kernel or something.. if any one can help to me would be very apreciate
3G over 2100Mhz is nice.
Gprs over 900 Mhz work fine but very very slow.
thank in advance

Hi I also have F240K from a week. I can't managed sim to work. Don't have any signal 2G/3G.
I tried most of the methods described here without success (flashing Telcel and Korean rom after, E988HK baseband, changing every setting in the service menu)
Which baseband do you use?
I can't use my new phone and I'm so desperate ;/

Hi, I sell my phone..really have seriously problem with the signal. I remenber that the best option was use the original rom...but anyway the signal was very bad. Sorry man.

Did you try flashing different basebands?

Thank You

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 )
see attachment
thx in advance

What is your location and carrier, and what bands do they use for 3G and LTE?

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).

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.

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).
