inmy Country Only Works Gsm 850, Does Anybody How To Change The Band The Htc Diamond, Cause This Phone Is A Tri Band And Works With 900 Gsm.
Can Anybody Helpme Please????
You can change the band in Comm Manager. There is a tab called Band.
And only assuming you bought the appropriate device, since if you bought the European device, then you do not have the 850 support.

Which country's running 850 mhz ... I thought that band was reserved for GSM-R (GSM Rail private network) - Or at least it is in the UK !.
I believe some countries in south america uses the 850band, and the US. It is wise to read the specs when you buy a phone. the current diamonds (european, asian) do not support 850. It would have been a quad-band band phone, not a tri-band if that was the case. There will probably be a US-version, but afaik it's not available as of now. sorry.
Im from South America, I thuoght that in my country works the 900 mhz, but only works with the 850mhz. I dont know what to do, i suppose i have to sell it on ebay cause nobody has a solution. thansk anyway
Why dont you return it to where you bought it from??...i dont know the laws of your country but if you have only had it a few days then you should be entitled to a refund as the phone is not suitable for you.

Somebody told me that there is a Software so you can change the GSM, and something abour the hardware, other guy told me about the Radio but i dont think so!!! i need some professional help please!!!
Try to flash the radio 1.00.25.05 or 1.00.25.06. I tested this two radio with VIVO Brazil that transmit on 850MHz and is working well.

Thanks my friend, im going to try it!!! I'll let you know what happens!!!
It didt work my friend, cause my phone is a Tri-Band phone, yours maybe is a Quad-Band phone. that radio is only fot Quad-Band phones.

You have a touch diamond, right? I have it too and also if on HTC site is wrote that diamond is tri band, with radio 1.00.25.05 and radio 1.00.25.06 is actually working as quad band GSM.
Check this post, the guy tested the quad band rom with a professional communication tester:

You have flashed the .05 radio? What carrier are you using?
im from colombia
i'm from colombia and i install the radio rom 25.05 and now is working in 850
before i installed the signal sucks with the 25.03... but now is better than never before.
i think that your need to reflash the 25.05 radio rom
Im going to try again my friend!!!!! My carrier is Movistar.
I would let you know what happens!!!!
thank you very much, i appreciatte your concern about my problem, thanks my friend!!!
it works!!!!!!!!!!!!!!!!!!!!!!! thanks my friend i really appreciatte!!!!!!!!!!!!!!!! you rule!!!!
Hello everyone.. I'm also from Colombia and I want to give you all information about what i did in order to solve the issue of the 850mHz.
I flashed HardSPL and ROM for Radio as indicated in:
http://forum.xda-developers.com/showthread.php?t=416211 (As many people I'm using HardSPL 1.40.OliNex
and Radio 1.00.25.05 )
I also flashed a cooked ROM from:
http://forum.xda-developers.com/showpost.php?p=2405336&postcount=1
I did all that yesterday so I havent been able to test signal outside from Bogota, but improvement on the device and the signal reception is obvious. I also did the test of dialing *#*#364#*#* on the key pad of the phone and I saw that the phone was working on the 850mHz frequency.
I have tested the device with two different carriers... Movistar and Comcel withouyt any problem. I was hoping with Comcel to get 3G signal (due to activation of 850mHz frequency) but still does not work. Some say that is imposible due to hardware issues, some other people says that Hardware in Diamond is capable of 3G US standard.... LETS SEE!!! HOPEFULLY SOME OF THE GURUS ARE WORKING ON THIS ISSUE.
It works in Mexico
Hello there.
Hell i bought mine directly from HTC, it was shipped with a spanish ROM 1.93 and radio .05. As soon as I inserted my GSM chip it worked with no problem. We are still waiting that some Dev found the key to allow our first gen diamond to work with 3G. Because imported phone onl ywork with 3.5G at 900mhz
Hi guys,
I've searched the O2X forum regarding 850mhz UMTS (HSPA) and found nothing so far. Does anyone here have the O2X P990h model which supports the 850mhz UMTS band? The only thing I can find is that the G2X supports 850 but has the model number P999.
I'm currently tossing up between the Atrix and O2X (I use the Australian NextG network btw). The locked bootloader on the Atrix sucks and coming from a S-Off'ed Desire I really want custom roms etc., but the O2X doesn't have 850mhz support which is a must for me, at least until now.
Since then I've stumbled onto these:
http://www.mobicity.com.au/lg-optimus-2x-nextg.html
They appear to be in a lot of other online shops as well, has anyone actually got one and can confirm normal O2X mods/roms work on the P990H?
Hi, i get 'h' on mine above the signal bars which i am guessing is hspa. (I'm in the UK on orange.) Or am I getting confused with something different?
Sorry if i am talking about something different.
Sent from my LG-P990 using XDA App
This is on czech LG site for O2X:
2G network: GSM 850/900/1800/1900 MHz
3G network: UMTS 900/1900/2100, HSDPA 7,2Mbps / HSUPA 5,7 Mbps
so i guess 850Mhz for UMTS is really not supported, at least not on EU model (but i doubt the specs will be different elsewhere on P990)
Actually he's talking about one listed as "LG P990H Optimus 2x 850/1900 "
It's on negrielectronics web site as well as a few others... but it seems impossible to find out any information on it. I myself am also interested..

No, completely different. The standard Optimus model number is P990. There is a 2nd model called the P990H which has 850mhz UMTS support (apparently at least).
So nobody has ever bought or used one of these phones?
where do you see a 850 umts version ?
Fido's LG P990hn is an 3g 850/1900/2100 phone. I'm curious that is it able to flash a p990's third party rom or not.

Don't take this as a definitive answer, but yes, it should be.
As you can see from the included screenshot, the ROM itself (via Hidden menu) lets you select 850 bands for both GSM and WCDMA, even though the radio doesn't support WCDMA-850 on the regular P990, which the screenshot is from. (This is from the new official Gingerbread, but it was the same on Froyo.)
You may run into other problems of course, like the ROM not liking your baseband, which is the one thing you probably shouldn't replace with stuff from the P990.
As stated, I cannot say for sure, but I think you can try without damaging your phone. (Or get someone else to try it on theirs ;-)) Which is my way of saying you probably should get a second opinion. And a third.
Cant you just get a G2X? Theyre 850 i think. Or you could join the dark side and use optus

Just saw this thread and wanted to clarify for anyone else who might stumble upon it.
P990HN from Fido does support 850Mhz and also works with all the custom roms/kernels for P990
I'm brazilian.
In Brazil, UMTS is 850/2100mhz
(990h model)
here in mexico 850 its the 3g band, the 8xxx baseband + canadian ril makes the phone p990h, but the radio its not capable on p990 celphone, you can just load miui or cm7 and load the 8xxx baseband and the canadian ril then you can upgrade your phone
I have the LG Optumus 2x - P990.
This phone has a software lock on the UMTS 850Mhz Band.
Does anyone know how to root this phone and unlock it?
My phone will sometimes connect to 3G here in Canada, but then it reverts back to Edge Network. If I turn my phone Off/ON, it will usually connect to 3G then after a few mintues goes to Edge. Certian parts of the city I'm in will connect to 3G at all times, it's very strange.
I did not know (and still confused) about what I was doing when I flashed my Fido LG P990hN with T-mobile CyanogenMod7. I can operate on Rogers network, but its not stable. Im new to this so I don't know what questions to ask - I just keep reading forums and help files. Michael

ok guys, here what I found.
I started separate thread in Q&A section:
http://forum.xda-developers.com/showthread.php?t=1521105
I'm in Ontario, Canada on Rogers. Got LG o2x from buddy who bought it in Europe. Then my mystery started. At home I was getting 3G and H, but at work (about 50km away) was getting only EDGE. But buddy with iPhone had 3G all the time. I got suspicios. Tried everything - flashing different ROMs, RILs, BBs... Same sh...it.
Then, my another buddy bought used LG 3D (Thrill) which was sold by Rogers (i.e. official Canadian edition) and asked me to root it. I did and tested - he had 4G (same as H, I guess) all the time. WTF!!!
So quest continues...
I found hidden menu in both phones. There I could force phone to use exact band I wanted. And mystery was solved...
So I forced:
GSM850 - my o2x got Edge; buddies: 3D Edge (the same)
GSM1900 (GSM PCS on phone) - my o2x: G; buddies: G
WCDMA1900 (UMTS_Band_II) - my o2x: H; buddies: 4G
and now...
WCDMA850 (UMTS_Band_V) - my o2x: NOTHING; buddies: 4G
So I made the conclusion that European o2x has WCDMA850 band disabled somehow. It explaines why I have H at home (big city where H is on WCDMA1900) and only Edge at work (small town and H is on WCDMA850).
Now I'm trying to find out if it's possible to unlock/enable WCDMA850 band on this phone. I read that Samsung has hidden menu where you can select bands you want to use.
Does somebody have and idea if there is something like that in LG?
Thanks!!!

There is, but it won't do you much good, as this is, to my knowledge, a hardware limitation. The P990 can not use the 850Mhz band, the P990h and P990hN can.
If you still want to try you'll find band selection in the hidden menu. Dial 1809#*990#, select Modem Setting/Band selection.

That's exactly what I did - went into hidden menu and selected each band one by one and then checked status in Engineering Mode of Modem Settings.
Now I have next idea: all this experiment I did while having "canadian" baseband 823. And i had WCDMA850 line in Band selection (but it didn't work).
Now I'm wondering if I still have WCDMA850 entry if I put "european" baseband 725. This will be my next step tonight. Because if I have WCDMA850 in 725 bb then I would assume that phone CAN handle it but it's disabled somehow.
What do you think?
I just thought that for manufacture like LG is easier to make just one universal phone and then limit available bands using software (or firmware)...
Thanks for ideas!!!
You'll find the (non-functioning) 850 band on European basebands as well.
I'm no electronics engineer, but I think there's more involved in supporting a specific frequency than just the baseband. (I think each frequency needs some kind of dedicated amplifier among other things.) The chip itself is capable of supporting 850 I think, but not the rest of the "supporting" electronics. I may be completely wrong though.
Basically the P990h is the revision which enables the 850 band. I think trying to get it to work on the regular P990 is futile, but you're of course free to try anything you want.
If I remember rightly, in the O2X review by Aandtech, they say that the 850 option is there in software but not there in hardware (on European version). So even though you can select it, it won't work. (At least that's according to the initial review)

1.) the LTE Frequencies vary from country to country...
From HTC:
EU: 800/1800/2600 MHz
US (AT&T): 700/850/AWS/1900 MHz
US (TMO): 700/AWS MHz
US (Sprint): 1900 MHz
Asia: 1800/2600 Mhz

Now comes the great news.. as far as I know Rogers uses 2600 MHz . so EU Version from the UK WILL work!
99% confident
EDIT:
Maybe this Thread can be moved to Q/A
Rogers should have the phone next Friday....given that is when the pre-order offer ends
the one that available now, only has one band that matches rogers LTE band :2600
as far as i know and read from XperiaZ forum, (c6603 XperiaZ has almost same LTE band as ONE)
no one are able to get LTE.
if you need LTE. get it from your provider.

Do they use the same frequencies in Canada as in the US? In the US, they use 700/1700/2100, and I think 1700/2100 (band 4) is their primary (most widely deployed). If that's true for Canada as well, all four phones should work on LTE. Obviously, I have not tested this so I cannot be sure.
Flashing a 6906 to a 6916 for wifi calling feature
Hey Guys!
I bought a Sony Z1 last year (6906) Canada boot loader locked to use on T-mobiles LTE network and everything worked great, only issue was I lost my Wi-Fi calling feature on the new model as it was not directly from T-Mobile and really liked the feature.
I see that T-Mobile released an almost identical version (6916), only I think has more memory and less bands available.
I tried to pull the wifi .apk file off my original android phone to see if I could make it work, and would not install assuming brand specific of permissions related.
so, wanted to pick the forums brain and see if any one out there has done this, take the firmware for a T-mobile branded 6916 model ( I believe current version is 14.2.C.0.159, until new kit kat release comes out if and when of course ) and put it on the 6906 model so the wifi calling feature can work.
Bands look to be there, so hoping this could work unless someone had a reliable work around for the Wi-Fi calling ?
Please excuse my noobness, new to Z1 forum so any and all help greatly appreciated
Thanks for any help in advance!
I thought bands and signal reception were hardware related not software related.

800,1800,2600
The answer is no.
The radios configuration each model has is programmed into the phone just like the serial number. The modem software just reads those values.

Maybe, but more importantly, there needs to be hardware support for the frequencies, which includes the modem, antenna and possibly a power amplifier. While modern chipsets support many LTE bands, the rest of the transceiving hardware will only be for the designed frequencies.
So for Italy, just buy one from UK, Germany or France, those have the European LTE bands (800, 1800, 2600), but of course no Moto Maker. So you have to decide what's more important. Aside from that, the AT&T model has LTE band 7 (2600), if that is enough for you.

I'd say yes, they change hardware parts. Supporting all LTE frequencies would cost too much space.
