O2X P990h (850mhz UMTS)

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.

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)

[Q] Which Version for T-Mobile?

Can someone tell me 100% for certain which version of the Incredible S I would need to be able to use on T-Mobile's 3G?

hey, I also wanna know about this... which is the best option either to buy HTC set in Malaysia, or buy a new one in US??

You want to get the s710e, I use that model on Tmo.

The Incredible S has all world bands as it is a world phone. It is unlocked, and can be used on any network, and can use all 3G speeds on any network.

not entirely true. yes, the Inc S box in your posts shows you can use all world networks for voice and EDGE networks. however, you need the 710a if you want to use at&t's 850/1900 3G network. looking at your picture, you'll notice that the 850/1900 band is not listed next HSPA/WCDMA settings. 710e is what's needed for T-Mo USA to access their 3G network

You are correct. Sorry about that. I thought it covered all 3G bands. I'm actually looking to get one myself for use on T-Mo USA, and the person who told me said it will work for both T-Mo and AT&T in USA, but now I see. At least it will work for my needs. I do have a question regarding the languages. For those who have one does it have English (US)? I'm currently using a Desire HD in the states, but it's only 2G here, and it only has English (UK), and it limits the phone for me.

My LG Thrill 4G is unlocked, but while I can make phone calls on it (I am on T-Mobile) the internet on it doesn't work at all. How do you get the internet to work on it?

Hi,
Please, does your LG thrill work on Tmobile in the US?
I unfortunately did not check for the band issue before purchasing my thrill 4G, unlocked.
Does Tmobile data work only on 1700 band?

I purchased an unlocked P925 from Ebay (says P925 on label behind the battery)...I loaded up the V21a_00.kdz file with Gingerbread. It now shows on the phone software as P920. Not a problem. Everything is working perfectly...email, mms, web, 3D apps, etc... Just like a newly purchased phone...just on T-Mobile service.
I'm using the phone on T-Mobile and my connection shows "H" in metro areas and "3G" in other areas. My "H" gets 9.7mb download and 1.9mb upload speeds (using speedtest).

LG P925 (or P920) with 4G or 3G for T-mobile USA network?

So, I'm using a P925 thrill AT&T branded which is UNLOCKED on T-mobile USA. But only getting 2G edge data speeds, and I'm being told no matter what I do, or what baseband I flash, I will never get anything other than edge on this device. My question is, is there a comparable device that DOES offer 3g/4g T-mobile USA compatibility?
I'm trying to migrate from unlocked iPhone's (again, using on T-mobile USA) to Android - simply because I'm bored of iPhone's... Have had them all except the 4S - but have a iPhone 4 so its pretty much the same thing. While I know the 3D of the Thrill is a little gimmicky, I think its one of the coolest "gimmicks" to hit in a long time, and because I only recently got a 3D TV -- well, recording 3D video's and watching them at home is pretty effin cool.
So, am I stuck with a T-mobile branded Galaxy device if I want 4G or 3G on T-mobile USA?
Any advice would be helpful, since I'm pretty much an Android Noob! THANKS!

If I remember correctly the optimus 3d might work with t-mobile usa. But you might have to double check just to make sure .

This is off topic, but how did you unlock your phone?

You should be able to use the 2100 UMTS band with T-Mobile, but I believe you need both the 1700 and 2100 bands for full 3G. If so, you need a baseband for either T-Mobile, Wind or another Canadian Carrier with T-Mo's 3G bands. The nice thing about this phone is it's flexibility of use with other networks by baseband flash. (Now we need other leaked GB basebands.... Ugh.)

If you want a non branded Android phone that works on Tmobile 3G/4G bands look at the Incredible S, Sensation (International Version), Sensation XE, Nexus Galaxy, the TELUS version of the Galaxy S II and the Nexus S.

I am in South Korea and will be moving to the UK soon.
I have the SU600 on SKT in Korea. It is rooted and I'm running Kangs CM on 4.0.3.
If I buy a UK sim card when I arrive, will the phone work fine for calls/messaging/data? I looked on gsmarena and the 2G frequencies seem to match up. But the 3G on the phone is HSDPA, but GSM arena says the UK needs UMTS 2100. Will it still work?
Would I need to get it unlocked in Korea before I leave?

From my experience, having a custom rom is effectively same as having a sim unlocked phone. So based on what you wrote, I have every expectation that you'll successfully use at least the 2g network in UK.
I bought my su660 in Korea too and now I am using it in the US. It turned out, however, that I cannot use the 3g hspa network here with T-Mobile because they require phones having both 1900 & 2100 bands. So I am stuck with just 2G for now.
So I would do careful research on what bands UK operators use before you head on over, especially if you really need 3g speed and if you are not planning on buying another phone anytime soon. I hope you will be in better luck than me.
Bon voyage and good luck!

You are wrong sim unlock has nothing to do with root/custom ROM. He has to unlock the SIM before.
And to unlock you need a STOCK LG ROM, froyo or gingerbread, as it needs lge hidden menu which isn't present in custom ROMs.
I unlocked last week I had to reflash a froyo LG Stock ROM.
Some people say that putting a SIM card from a different network pops up the unlock option at boot but couldn't try.

I imported an ATT Atrix for using in Mexico with Telcel Carrier, and when I first inserted the Telcel Sim Card, the Sim Unlock Menu popped. So yes, maybe your Optimux 2x is already unlocked.
Anyway, you can unlock your phone anytime and in anyplace. Just insert a sim card from another Carrier Company and the option should be showed.

Cool, I will check the SIM unlock then.
How about the frequencies it uses?
According to gsmarena the SU660 has 2G Network GSM 850 / 900 / 1800 / 1900 3G Network HSDPA
The UK frequencies for 2G are Required GSM 900. Recommended GSM 900 and GSM 1800. and 3G Required UMTS 2100.
I'm guessing that this means the 2G will work, but 3G won't? Can someone tell me if this is correct, I don't fully understand what it means with the SU660 having HSDPA. Is this a different to UMTS??

Hsdpa is UMTS.

That could be a bit misleading because the 2x I have here in Australia has 2100 and 900 but no 850. 850 is used exclusively by one carrier here.
So, the link may depend on in which region the 2x is sold.
