A definitive answer to the UMTS quad band question - T-Mobile LG G2x

Hi,
I've read through plenty of threads (including that massive 350 post thread) on whether we have quadband UMTS in hardware or not? The answers there weren't very clear, so I went to the LG homepage, and they seem to have updated their brochure to mention only the AWS bands after a lot of complaints from our side. Some T-Mo reps state the hardware is present but the software isn't, while others completely say that there is no hardware at all.
After that I read through the service manual, and in that various pages there is only reference to the AWS band and Band 1. I've snipped a few screenies and uploaded it here - http://simkill.imgur.com/g2x
This confirms beyond all shadow of doubt that there is NO HARDWARE support for global UMTS bands.
Shame really, I didn't mind waiting it out till someone came up with an updated baseband.

I wouldn't call it definitive.

Well why not, I'd like to see more than just a statement, although my title may have been a bit sensationalist I'm almost certain about this.
I read through the manual, and although in many many places it says that those internals have *support for 900/1900*. But nowhere are proper working specifications/test results been mentioned for the other bands. If you have any information, now would be a very good time to share since I'm planning on returning this in favour of the O2X in two days.

Unfortunately I don't think anyone has that information. Only time will tell. I'm not ruling out the possibility because it isn't supported currently though. Something just strikes me as strange.
If AT&T 3G is a frequency you require then flip to the O2X.
Is there a radio for the O2x? Has anyone taken the phones apart to compare the chipsets?
Too many unknowns to be definitive. But your pressed against time so I understand.

I really liked the G2x, it was everything I wanted in a phone including HSPA+ but alas, it wasn't meant to be. I really want to be wrong on this to be honest.
Yeah, later on tonight I plan to search for service manuals for the O2X, and read through them as well.

HTC Pro 3G connection problems

I may get flamed for this but I did try and search the WIKI and the Raphael forum. I just purchased an HTC Touch Pro as someone threw me in a pool with my Kaiser still attached to me. I got it through Expansys which I believe is a company in the UK. When I turned it on I saw I was only getting the EDGE network. After doing some research now I see that I may have messed up and I may not be able to connect to the 3G network here in North America. Is this true? Can someone PLEASE confirm this for me? Is there a new ROM I can install or a radio upgrade that will allow this phone to connect to AT&T's service here in the US? PLEASE PLEASE PLEASE let me know. This phone is badass and is a huge improvement on the Kaiser. I'd love to get it to work, but the internet speed is the most important thing to me as I'm a systems engineer and tether with it almost daily for work. I hope someone can give me a definitive answer on whether or not I should send this beauty back. Thanks ahead of time for any input whatsoever!
definitive answer: NO
no 3g in USA on at&t or t-mobile
only way is to wait for the FUZE
htc said its not software its hardware!
sorry i know it sux but if u can return it and wait for the fuze, go ahead!
Aaaaaaaaaaa!!!!!!!!!!
That suuuuuucks! Well, thanks for your quick reply. I guess I'm going to have to see what I can do about returning this thing. Any idea what the ETA on the Fuze is?
Once again, I really appreciate your help. I've been slammed here at work so I haven't had a chance to do the research that I would normally do. I especially appreciate your definitive answer
The Fuze should be released in the next few weeks. The exact date is not known. But by the end of November is almost a guarantee.
Thanks to all!!!
Thanks again. I guess I'll wait for the Fuze. From the pics it looks like they did the same thing as with the Kaiser and removed the front camera for video phone. I guess AT&T is worried about bandwidth issues if everyone starts making video calls. Funny thing is, most people here in North America believe very strongly that we are the most technologically advanced country in the world, yet we can't seem to even compete with other countries, including third world countries like South Africa, on many things including cell phones and reception.
http://forum.xda-developers.com/showthread.php?t=420865
check this thread,complete coverage of the issue...
All post from viper are particulary informative. Still a little bit of hope...
Well AT&T isn't even setup to handle video calls (afaik), so I don't think it's something they're "worried" about.
Awesome labbbby!
Don't know why I couldn't find that thread earlier. It's exactly what I was looking for. I guess I'll wait a liiiiiittle bit. I don't want to part with this thing. Besides, I'm addicted to that damn teeter game.

So you spend God-knows-how-much on a device without researching it well enough in the first place. Wow.
Well unlocked GSM Touch Pros use 3G on the 2100mhz freq (European) and U.S 3G is on the 850/1900mhz freq (T-mobile chose the 1700mhz route..don't ask why).
Send it back and wait for the U.S version which is branded through ATT as the Fuze.
I should have said, "almost all input is welcome"

I know I said I welcome ANY input. I didn't really expect the sarcasm though. I'm in the middle of moving our offices and being that I'm the IT director it's pretty demanding. I have owned the 8125 (Wizard), the 8525 (Hermes), and the 8925 (Kaiser) before this one. When my Kaiser got ruined I was forced to replace it ASAP because I need instant email/contacts/calendar, tethering, and I use it as my GPS. I figured instead of shelling out $400-$500 for a new Kaiser quickly, I may as well add a couple hundred more and get an upgrade. My mistake I guess. Normally I'm more careful but under these circumstances I didn't have the luxury. I guess thanks for the input anyway. Next time try and be a little nicer to strangers.
Interesting change
While looking at what exactly I had purchased from Expansys I saw that they touted the phone as being, "Quad-band GSM/GPRS/EDGE: 850/900/1800/1900 MHz (Band frequency and data speed are operator dependent)". This would lead me to believe that it should be able to connect to the AT&T network here as it says it can connect to the 850/1900MHz frequency. I also looked underneath the battery to see the exact model and it's a RAPH100. I could swear I saw somewhere that this is the new North American version. I'm doing some more research and I'll post whatever I find in case it helps someone else in the future with my issue.
Sorry but almost all of us have the RAPH100 and we're all stuck with an almost useless g-note phone. It was an expensive lesson that may be salvageable if a radio antenna mod gets discovered and if not... it'll make a great paperweight.
I'm looking forward to the X1 or X1a or X1i or whatever they call it today.
Dammit
Well, I guess my ray of hope is now crushed. I can't wait around for a mod. I'm going to continue trying to send it back. I can't believe that they would say it connects to that frequency and not actually work. That's terrible. It reminds me of the whole problem with the missing drivers on the Kaiser. Time for another htclassaction.org website.

Expansys have quoted correctly. GSM, GPRS and EDGE are all supported at these frequencies, but none of those technologies are 3G
Good luck getting a refund - it's not the retailers fault you didn't understand what you were buying

Maybe they shouldn't sell a 3G phone in the US that doesn't do 3G. It's kind of hard in today's world to be up on every single kind of technology so one expects a company to list major issues such as this. I apologize that I'm not as knowledgeable as you about phone frequencies and protocols. I do know that there are a lot of other technical fields that I'm very knowledgeable about and would definitely try and give someone help without trying to put them down or make them look stupid because they didn't understand something that is not part of their expertise.

AT&T users check out post "How to turn off 3G"

This rom is totally different from the UK version which I have on my D2. Notice the option to use 3G 1900/850. Does this mean the D2 has a way to access those bands in the US already in the hardware??
Wow, good eye. I switched it (WWE edition rom) to the 1900+850 one but no 3G icon for me. I know it is finnicky in my area so possibly it might work. If it does then I might not sell it after all.
please 3g.......
I know! That is exactly what I am thinking. If there is a way to turn on those bands I will hold on to this one for a bit longer. There is a chance they are different like with the X1a and X1i, but I really hope not. Once we get HardSpl I want to get my hands on that Rom.
I saw those bands. I went to AT&T store and tried a card from an employee there. NO 3G. The bands being in there do make me wonder if 3G will work but all say it is Hardware related and not Software. That is true but the Radio could have those bands but they are just disabled. Was this not the case for the diamond or something and HTC had on the website a ROM to make it QuadBand rather than triband. How it originally shipped?
The other discussion is here.

[Q] Compatibility in the US

Hey,
I'm heading back to the US after being in SK for a bit. I'm considering getting a LG LU6200; save for the battery life, it's an amazing phone for the price. Anyway, I'm wondering if I'd be able to use it in the US.
I saw that the phone operates on the 2100 band for 3G (HSDPA), which Metro PCS and T-Mobile operates on accd. to Wiki, and the 800 band for 4G, which Sprint operates on.
Theoretically this should be possible, but I've just had a friend who's moved back to the States w/ the same phone that said something to the effect that he couldn't. But he also only tried Verizon. =/
Since most folks here probably haven't used this phone, I'm wondering whether or not you've been in a similar situation that ended in success. (ie Have you been able to use a non-US phone with US carriers?)
Also, I'm wondering whether or not this is a good idea since I'd be restricted to a single band, which I assume increases the likeliness of dropped calls/weak signals, etc.
I've asked other forums, but haven't really gotten a response.
Thanks

Buying a phone in the USA for use in Europe

Hi there,
I will be visiting the USA this summer and since the swedish crown is fairly high compared to the dollar, the prices are really good compared to the swedish ones. I am thus considering buying a new phone there, and would like to know if, and then what, problems might arise that I need to look out for.
I realize I need to make sure it isn't locked to a carrier for obvious reasons. Are phones today sold with bands unique to different regions or are all bands included to make sure the calling works no matter where I am? Furthermore, will there be any issues with other connectivity, like 3g, 4g or wifi?
any input is much appreciated!

Quad band (also known as quad-band or quadband) literally means four bands. Having more than one frequency in one device is useful to enable roaming between different countries that peg the allowed transmission frequency at different values or to allow a better coverage in the same country.
If you are using your phone internationally and also do travel extensively in the USA, and you wish to be connected at all times with your work or your family, than you must buy a phone with this function. Otherwise, any phone will do just fine, even the really inexpensive ones...

Thank you for your answer!
Other than the quad band, nowthing else is needed? I believe I read somewhere that even wifi-connection could be different in different regions, how about that?
Anything else I need to consider?

If a phone has "Wi-Fi CERTIFIED" sticker it flawlessly works overall in the world. You must not have any concerns.
Ok, so as long as it's quad band, wifi certified and is not locked to a certain carrier nothing should be a problem? How hard would such a phone be to find in the USA?

[Q] How can the 4G frequency be changed from 1700mhz to 1800 mhz

I've searched for 3 days now, trying to get some info on this, there are various discussions on xda and on other sites that come along the same line, most of the answers are:
No it can't be done - it's hardware related - there are different variants for each region (seems this is not the case with the ONE)
You need someone with QPST but it probably can not be done.
But there is none that actually clears it up, it's mostly "I think it is...................."
What I found out is that the chip regulating 4G LTE connectivity on all HTC one variants is the same (600 MHz Hexagon QDSP6V5A part of the MSM8974 chip and it can sport the ALL LTE frequencies), so it is not a hardware difference between the EMEA and the Verizon, now the question is do I need someone with this QPST or will it only be a case of changing the baseband - all this, is my own conclusion, feel free to give me feedback on this
now on the Verizon site LTE spec says:
Network: LTE Band 13/4 (700/1700 MHz)
CDMA/1xEVDO Rev. A (800/1900 MHz)
the HTC site for Verizon says 4G LTE:
EMEA: 800/900/1800/2600 MHz
Verizon: 700/AWS/1800/2600 MHz
Yet I still don't get any 4G
Sadly there is so much info and it's hard to follow it all. So please can someone explain what and how things actually work?
Why do I need to know all this? Cause I have a Verizon m8 and I'm using it in Europe and I can't get 4G - atm I'm using Insertcoin with ElementalX 8.0.5 kernel and everything is working on the phone aside 4G - I flashed various roms on it, never had ANY problem, aside small things that a Google search solved.
Anyone that can enlighten me? Any help would be appreciated.

Each model must have a different *antenna* configuration so that they are optimized to their respective regions. The *antenna* is separate from the actual radio you mentioned above. This is why there are so many models, which I thought I had explained in this thread: http://forum.xda-developers.com/showthread.php?t=2710720&page=5
Even if you could override what band the phone connected to, the performance would be abysmal. The fix for this would be to physically change the antenna. If you could do this on your own, you deserve an honorary degree in electrical engineering since antenna design isn’t the easiest thing in the world. Here’s where to start: http://en.wikipedia.org/wiki/Maxwell's_equations
Since there is a discrepancy between the Verizon and HTC spec sheets, I would do the following:
1.) Focus your research on seeing which one is correct by contacting HTC and Verizon.
2.) If Verizon’s is correct, you’re done. Romania’s carriers only transmit LTE on 1800 Mhz (band 3). Otherwise…
3.) If HTC’s sheet is correct, focus on why you can’t detect 1800 MHz. It must be something in your unlock method or Verizon really locked the hell out of the radios for some reason.

Cheers mate, went to an actual engineer that handles repairs here in Romania for various brands and we both decided to make it our own personal project to make this happen a Verizon M8 turned into a Euro version one, ill report back with the results in about 2 weeks. Seems technically it can be done, just needs a some work. Thanks again for the reply though.

Hi Macusu,
Just to remember, I believe the problem is not only related to the antenna itself, maybe there are other kind of locks since, as discussed in the other topic, Here in Brazil and I`m not being able to attach it to 4G 2600MHz (Even if the phone supports this frequency).

Thing is they are waiting for all the tools atm, I mean they don't yet have all the new kits for it, it should be arriving, and the engineer is actually a certified person being one that works in a certified HTC service, so once we get the entire .... kit, he will start working on it toghther with the software engineer and so on, hope that it will all sort out, i did get another phone in the mean time as well, but as i said i will be reporting back.
Thank
