band switch malfunction - MDA, XDA, 1010 Software Upgrading

Hi All,
This is the first message forum I have ever used, please be gentle. Yes I have donated, if I was too cheap then say so, I'll give more.
I switched from ATT to T-Mobile last fall with my Siemens SX56. I unlocked it using XDA Unlock program. All worked well at the time. Phone would not work in Europe last week.
I have the following error both in the US and Europe and I would like help with resolving:
"the band switch screen displays "Current: ERROR" when viewed" If I attempt to change band my phone portion turns off then reacquires T-Mobile network and all seems ok. Is this error message accurate? What must I do to correct this problem and ensure my phone will work in Europe?
I would be delighted to work with some one in the Orlando Florida area to perform all the latest updates and resolve this problem.
Thanks, Scott

us based dualband phones like xda1's will work on 900/1900 in us
eu based dualband ones will work on 900/1800 other places
you cant change that
you can only use a us based phone places where they use 900/1800 if you use an operator that use 900
the bootloader changer dont work
it's a hardware thing

Unlocking to enable orange

I have managed to unlock my sx 56 from at&t using xda's software. Great. Trouble is it only enabled me to use O2 in the UK, i then went to yorch.net and downloaded more software which enabled vodafone and O2. Better. But I was wondering how I could unlock it so all networks worked. Can anyone give me a hand?

What you'll find is that there were two versions of the XDA (AKA...). One which was sold in Europe and ran on 900 and 1800Mhz frequencies, and one which ran on 900 and 1900Mhz frequencies, and was sold in the US (SX56, MDA, etc).
You may or may not know that Orange UK runs solely on 1800Mhz (as does T-Mobile), and as such you'll find your version to be incompatible with these networks... Sorry.
Although this device is from the states, I have found the option of using it oat 900 gsm or 900 / 1800 gsm or solely 1800 gsm. Does this mean that I may be able to use orange ?

Although it might give you this option, I believe that the radio hardware inside it is designed only for 900/1900mhz. I guess you could try and put an Orange SIM in, in an area where you know there to be coverage, and see if it works. It is unlikely to work on Orange or T-Mobile.
Let us know either way, cheers
I have tried my sim in an area I know there to be coverage. It just comes up as no signal. Since going through the site I'm thinking of getting a serial cable and using manipulator although its a little ambiguous about whether this will work. One company reckons they can do it but if what you say is correct then they'll be waisting their time and my money.
It might be easier to swap providers!
Beini, if your phone is 900/1900 it will not work on Orange which is 1800.
O2 XDA RUNNING ON ORANGE NETWORK FINE NO CONNECT TO INTERNET
Thanks guys for showing me how unlock my 02 XDA so I can phone out. But I just cant get it to connect to the internet - can anyone help me?
I dont have the option for 1800 (Baud Rate)
i suppose the getting access to the internet is going to be impossible...??
How do I configure it to atleast work for WAP?

HELP requested with using a 900/1900 in a 900/1800 country

hello:
i know that this topic has been addressed, but it's not clear what the answer is:
i have a friend that bought the "b" model xda (900/1900) in the united states, and took it to brasil. he ran XDAunlock, and the sim is unlocked.
with bootloader, he told the phone to operate at 900/1800. the program
"bandswitcher" or something that's included in the xda developer's rom
indicates that the phone is at 900/1800.
but it gets no signal using sim cards in sao paolo, brasil.
many posters have indicated that they do get some connectivity,
not quite what a native 900/1800 would get, but much better than nothing.
other posters have said that it is not possible to get any signal, since there is a hardware difference that can't be compensated for with software.
who is right? is there anyone from brazil that has gotten a 900/1900 phone to work that could tell me how they did it, what city they're in, and what provider they use?
if it's true there is a hardware difference, is there a user-friendly way to swap out some internal part to make the bandwidth change?
any firm answers appreciated; if you are only guessing (like assuming that since wallaby bootloader mentions switching bandwidth, it's therefore possible), then please say so. i'd really like to know for sure what the story is.
thanks guys!
The 900/1900 gsm phone was never intended to work at 1800, some people manage to get signal but there are many factors involved such as proximity to mast, the fact is you are trying to use it off tune, try listening to a radio station 100mhz away from the advertised frequency and see how it sounds, if you were right next to the transmitter you would probably hear it because it would break through on to adjacent bands, but go further away and the discrepancy would become more obvious. If you need to work on 1800 get another phone or sell it and get the correct model.
hi,
let ur friend ask the operator there if they have 900 MHz signal. if yes, then all he has to do is to select this band on both GSM menu at the bootloader and in the phone settings.
good luck

Band restriction hardware or software?

I live in southern africa where its still going to be some time before the G1 is launched.
It would be possible for me to order the US G1 from ebay but I am concerned about the network band because firstly I want to know that the phone will at least work on the regular 2G network (1800 in my country) for the usual phone calls and then of course I want to be able use 3G for Internet access. I don't know the 3G frequency in my country but the service has been available for over a year already.
Is it a software restriction which can be resolved by updating the firmware at a later stage or is there actually different hardware for the model being released in the US and those being released in other countries like the UK?
Thanks!
Take a look here to find the UMTS frequency that your carrier uses (of course, call to double check):
http://en.wikipedia.org/wiki/List_of_Deployed_UMTS_networks
It hasn't exactly been confirmed yet, but the G1 is supposed to support both 1700+2100 (UMTS IV) and 2100 (UMTS I) networks. Since African carriers are all using 2100, you should have no problems getting a 3G signal without having to worry about hardware/software compatability. You should also confirm that your carrier will provide the approrpiate connection settings in case you need to set it up manually.
The G1 also comes with quad-band GSM/EDGE, so you will certainly be able to receive 2G signals.
However, keep in mind that the first batch of G1s will be locked to T-mobile. You will need to make sure that you get a carrier-unlocked device in order to use your carrier's SIM.

Thanks, that makes me feel more comfortable with ordering a G1 from the US.
I was just concerned because I read somewhere that the US version does not work in AUS so there obviously are problems in some countries with the bands. The UK version will apparently work in Aus.
Again, I want to emphasize that you need to make sure you have an unlocked version. When you first turn on the phone, you are required to log into gmail (or create a new account) over a 2G/3G network. If you are unable to login (because the phone has not been unlocked to work on your carrier's 2G/3G), you will not be able to use the G1 for anything other than emergency calls. You won't even be able to enable WiFi to handle the login.
http://androidcentral.com/g1-wont-work-without-a-data-plan-period/
If at all possible, I would advise waiting at least until some other folks have tried bringing the G1 to other networks so that you know what exactly you will have to do to get one working on your carrier.
Thanks again, I will definitely ensure that I do not purchase a network locked G1.

any way to use t-mobil 3g with Hermis

All. I have an 8525 unlocked and working on T-mobil in USA. Edge Data is working via T-zones. Is there any hack to get this device to use the new T-mobil 3G net? Please Advise Pogo...
I had to turn off 3G in order to get my MMS to work.
as far as i know tmobile in usa
use different 3g frequencies then the
rest of the world
and not software hack can change
what frequencies htc devices support
nor different radio-stack
it's a hardware thing

This is partially false. T-Mobile USA uses BOTH AWSIII (1700) and 2100 frequencies in the US.
As for the OP, I am in the same position, and am unable to get 3g working. I know for a fact that it exists in my area (I randomly was on it once for about 10 minutes) but I can't get it to truly work. Unsure if it has to do with provisioning (I think it does) or not.

[Q] Differences Between E900 & E900h

Guys, anybody knows if really have any "real" difference between the E900 and E900h versions?
I am asking this because I own an Orange-FR E900 and as widely said, this version doesn't support UMTS 850. Even in the box of my handset only shows "WCDMA 900/1900/2100, GSM 850/900/1800/1900".
But I never had any problem using it anywhere I went in the American continent, even before I flashed it with the Open-EU ROM.
With the original French ROM, I had used it both in 3G and 3G+ successfully here in Brazil with Vivo, Oi and Claro SIMs (all UMTS 850/2100), in Argentina with a Personal Telecom SIM (UMTS 850/1900) and Canada on Fido (UMTS 850/1900).
Now with Open-EU ROM and the Tim SIM (UMTS 850/2100), I performed a simple test on Band Settings. With "WCDMA 850" set, I got the "3G" sign at the Status Bar, and with "WCDMA 2100" I got the "H" sign that replaced the "3G+" from the previous ROM.
So I'm guessing what is the deal here? Luckily I got one "factory all-unlocked bands" or all those "Euro-Spec / American-Spec" thing is just bs they told to us to avoid "bootlegging"?
Where did you get the OPEN EU ROM?? I can't find it.
As you know I am having problems connecting to UMTS 850 here with Claro Peru and I think is due to a software (ROM) lock or stuff like that and I wanna re-flash my phone E900 using the OPEN EU ROM.
Please, give me the URL to get the ROM. Did you get some issues with the new ROM? maybe camera or marketplace access?
Thank you

I got the ROM and all instructions here: http://forum.xda-developers.com/showthread.php?t=935578
I recommend you to read the entire thread before flashing your device. Information is never too much
PS.: Don't try to flash your E900 with an E900h ROM (and vice versa). If you do that, you gonna brick your device.
There are actually very minor differences, between the two. I have yet to compare actual parts models, but here are the sevice manuals, with all individual components teared down and outlined. Take a look, perhaps it would clarify something. The manuals are very long, of course.

Hi, I just got an E900 (It was a gift) I can't get a 3G signal in Telcel's (México) Network which uses a 850/1900 band. The phone is OPEN, is not locked in any form and came from factory with Mango.
I have tried all the possible band configurations through the MFG app but can't get a "3G" signal. Here is the question, is there any possibility to get the phone to work with Telcel's 3G Network or Am I wasting my time?
Best Regards

You are wasting your time, you need an e900h to get UMTS or 3G on the 850mhz band.
I've got both an used unlocked Vodafone E900 (carrier still says Vodafone - how do I get it to open) and a brand new Telus E900h with me and can't decide which one to keep.
E900H will have to be unlocked and it's asking me for PIN right now. But it has 850 signal and since I'm using Tmobile US with it I should be able to get 3G. With the E900 I'll only be able to get Edge on T-mobile unless if I switch to ATT but they're pay as you go plan isn't as nice.
But it seems that you aren't able to get internet sharing to work on E900h since Telus hasn't released it. That option is available to E900.
Are there any other differences? Which one should I keep? I've a tendency to lose phones but I don't think I'll want to keep both around.
