Is anyone else running this cab file??
Before loading it, I pulled it apart with a cab editor to see what it was. I was very excited to see that it uncovered the radio band selction capabilities, so I quickly installed it.
But this where things got funny. I refuses to give me the option for the for GSM 1900, although it is clearly called out in the registry edits the cab lays down. I am running the 1.13 radio, with system 1.40.00, and was wonder if anyone else can verify this as a problem? I am wondering if this is a software issue in either the cab, system, or radio... Or to my horror is the SX66 retarded to triband???

Ok, looks like TheLastOne answered my question in another post. Funny that the site search failed to turn this up:
1) Phone Band Selection: BandSel_BAWWE_140921.sa.CAB
- I've played with this a bit, their cab is actually ****ed up, as they have tried to get 6 selections onto the page when only 5 are possible. Through the registry you can have any band configuration you want selectable. I personally LOVE this feature.
GSM 1900 is the 6th selection, hence it doesn't show up. But this now leaves a glaring question, what are ALL the selectable options? I note the 900/1800 option with a value of 3, but is there a 850/1900 option(This would be prefect when I go to aruba), and what is that value??
GSM900 has a value of 1
GSM1800 has a value of 2
GSM900/1800 has a value of 3
GSM1900 has a value of 4
Automatic has a value of 7
gsm850 has a value of 8
So, what are values 5 and 6?? I could set those values, but I have no idea how I'd check to see what band I am current using. Anyone got any thoughts?
-Chris

Either 5 or 6 is 850/1900, from my tests, but I forget which.

If you don't mind, how did you determine that?
-Chris

In my location, I have access to two GSM networks, one which is exclusively 1900 and the other is 850. Set to either 5 or 6, I could get on both. (So I'm not positive it's EXCLUSIVELY 1900 and 850, since there is no 900 or 1800 here to test).
I did this a bit ago, so I don't properly remember.

The value is a bitmask:
bit 1: 900
bit 2: 1800
bit 3: 1900
bit 4: 850
so 5 means 101b - 1900+900
6 means 110b - 1900+1800
Setting 7 would make GSM to use 900, 1800, 1900
Probably the GSM part also tries to register on 850Mhz when 1900 is selected.

Mamaich,
You rock. You never cease to amaze me. Very cool, thanks.

Can you post a link to this CAB file?

Modified Band Select CAB for USA
I modified the CAB for USA only 850, 1900 and Auto

I ran the updated CAB file you posted here, seems to be working ok, although signal strength (on the new bands) seems to be weaker than what I had before installing the cab. I am wondering, is there ever away to revert back to the original band options or settings ?

I am wondering the same thing, because NONE of the 3 options i had available to me when I installed this (Auto, GSM 850/1900 (NA), GSM 900/1800(Euro/Asia) were selected.
When I selected Auto, I began ROAMING, and I'm not certain why. The only way I know of to return this back to factory state is to hard reset.
Does anyone have THE ORIGINAL CAB, before the mods were made so that ALL options were available?? I'd really like to have that cab so that I can see what option my PDA2k on Cingular was using...

Here is the original CAB file, it did not work on my SX66 (see the first few posts on this thread) so I modified it to use only 850/1900 and Auto. I have had no problems with the modified CAB. Signal strength has not been degraded.

thanks, Cruzzer.
the modified CAB put me into permanent ROAM no matter what frequency I chose (or killed the phone entirely because there wasn't a 900/1800 tower).
I managed to get a hold of Chris and he helped me make some registry mods that gave me the original functionality back.
Interestingly enough, I had to put the phone thru a couple of different SR's before it would stop roaming, even after switching back to JUST 850.
Goofy, huh?

Care to go over the registry edit you made? Thanks.

Question
First of all, thans for the Band Select created by Cruzzer for US users. After I install his band select, it's the first time that I can use my phone in my office located in a basement. But I have a problem. In his band select, there are three options, automatic, GSM 850, and GSM 1900. When I selected automatic, my phone couldn't find the network. But when I selected GSM 850, it works perfectly. At first, I understand that by selecting my phone to automatic, my phone should search both GSM 850 and GSM 1900. But I don't know why it always show no network. Did I do anything wrong?
By the way, my phone is O2 XDA IIs brought from Thailand. (O2 Asia)

I believe that there is a bug in BA when working with GSM850.
In fact, automatic should search between GSM850, 900, 1800 and 1900.
Usually when using "automatic" where GSM850 networks exists, makes BA not being able to find any network.
Are you using WM2003SE ?
JP

Yep WM2003SE
Yes, I'm using WM2003SE.
I also tried another band select created by one of our members in http://forum.xda-developers.com/showthread.php?t=297099 His band select gives four options:
1. automatic
2. GSM 850/GSM 1900 (north america)
3. GSM 900/GSM 1800 (Europe)
4. Reset Values to Zero
When I selected GSM 850/GSM 1900 (north america), my phone had no signal. So, right now I have to go back to BandSel_BAWWE_140921.sa.us and manually select GSM 850.

Yes, unfortunely, that seems to confirm my teory.
If it works for you at 850, keep at that. Just remember that if you upgrade to WM6, band selection will not be available and it will be locked to your choice done in WM2003, in this case 850.
Your BA, will no longer be quad-band (the same as mine).
JP

Too bad
Thanks for confirming the bug in BA. Too bad. I want to upgrade to WM6 but I know there is no way to select which band in WM6. So...I'm stuck with WM2003SE. I wonder, can we edit the registry to manually select the GSM band in WM6?

I've tryed and some other did also, but it seems that both the .cab and also registry tweaks for band selection do not work on WM6.
It does not mean that you will have a problem with WM6, but rather that the band that you have selected on WM2003 will remain "locked" when using WM6 and cannot be changed.
In my case, i'm using the 900/1800 band selection and it works just fine with WM6 (i've used Helmi's and now i'm using Xplode's) but i cannot select 850 for example.

Network choice issues

Hi All,
I've got a standard HTC branded kaiser.
Where I live I've got access to a 900/1800MHz GSM network (for backup) as well as 2 seperate UMTS networks on 2100 & 850MHz.
I'd really like the phone to use the networks in this order:
850MHz UMTS (Primary carrier)
2100MHz UMTS (Roaming agreement)
900/1800 GSM (Primary carrier)
Unfortunately I can't make it happen ....
* If the phone is set to auto (GSM/UMTS) and also auto band, it locks onto the 2100 UMTS and stays there. UMTS>GSM. This is the case even if I deselect the roaming carrier from network preferences.
* If I lock the phone band to GSM(900/1800)+UMTS(2100) it behaves the same as above.
* If I lock the phone band to GSM(1900+850)+UMTS(1900+850) it then will lock onto the correct 1st choice, but it won't fallback to GSM
So how can I make this work? Ideally I need a band option like GSM(900/1800)+UMTS(850/2100), but it just isn't gonna happen.
Even though this is a quad band GSM and triple band UMTS phone I'm forced to choose a combination that isn't optimal?
Any ideas?

3G in the USA

Has any been able to get 3G to work in the USA yet?
thank you,
jdm

I would say that it is imminent that the US version of the S730 will be released soon. AT&T or T-Mobile may pick it up (T-Mobile's 3G network in NYC just went live, but there are no phones). If so, I would suspect that some of these crafty folks (like Alcaline) would be able to extract the radio ROM, and make it available for the S730 that we all have (the european version).
But, here's the most important part... It all depends on whether or not the European version of the S730 has the radio chipsets that will support 3G on the frequencies that are 3G in the US. There is no known answer "available" to this, so it can only be discovered by testing.

The current S730 uses the 2100 band for 3G speeds and ATT is deploying 3g on 1900 and 850 I believe and they sell a decent ammount of 3g phones. T-Mobile is working on setting one up on the 1700/2100 band but I dont care for T-Mobile.
I have watched my phone at times flip into 3G mode for a few minutes then revert back to Edge, its trying but cant work properly without the right frequencies.

Check out the chipset datasheet. Bottom of page three explains the specific radio chipset combos and their support for different freqs.
I suppose, to save on manufacturing costs, they could have used the single chipset that supports 3G on all freqs (RTR 6285), but I believe this is unlikely due to the difference in model number that was submitted to the FCC (European version: WING220, US version: WING200).
Who knows though.

3G in US
Hermes models had different model #'s HERM100, HERM200 and had the same radios, in some cases minor difference such as case style, i.e removal of video calling camera etc. With any luck we have the RFR6500 + RTR6275 Combo, or as you mentioned the RTR6285 and just not a radio rom that allows 1900+850 3G. I was looking on the FCC site and they have some interesting screen shots, one of which shows one(s730) with what appears to be the front camera covered up and another which shows a radio rom(R 0.27.03.05B), one that, to do the tests would likely need to support 1900+850. Check Page 250 / 11 in the PDF. However, also in the test is the lack of any mention of 2100 Mhz test, which would suggest that either the US 3G Radio won't support 2100Mhz or that it indeed has different hardware that won't support 2100Mhz. At any rate it would be interesting to know if anyone has tried to flash one of the pre-prod roms for the wing 200 onto the wing220 and see if they are able to connect up to 1900+850 3G.
http://gullfoss2.fcc.gov/prod/oet/forms/blobs/retrieve.cgi?attachment_id=890469&native_or_pdf=pdf
I suppose only time will tell.

Wow... nice investigative work. Very interesting. I'll start hunting around for the ROM.
[edit]
Searched google and, my favorite, napalm with no luck. I wonder if we can lure an FCC testing engineer into the XDA-dev realm. muahahaha

I was searching some of the other posts, and it appears that most of the pre-prod radio rom testing had been focused on GPS functionality. Has anyone been able to throw on any of the pre-prod radios with an ATT SIM and tested to see if it can connect to WCDMA -> US Band (1900+850) ??

I have no possibility to check the 3G in the USA from my location in Norway.
But just to get this clear, because I have changed my Radio more often then most people change their underweare.
Is everybody able to select WCDMA and then US Band in the settings?
I dont know if this is selectable on all devices or if this is made available after my radio flahings.

I believe all S730's have the following options available.
Network Type:
Auto
GSM
WCDMA
Band Type:
Auto
US Band
Euro Band
Japan Band
For it to actually be able to operate on all of these frequencies I believe it would need to use the the RTR6285 chipset as the other 2 combos would not support all of the different frequencies combinations.
US Band -> GSM 850+1900 / UMTS 850+1900 (ATT)
Euro Band -> GSM 900+1800 / UMTS 2100
Japan Band -> UMTS 2100+800 (not positive on this one)
If I change band to from Auto -> WCDMA I do not get an error but no 3G Icon and all calls fail. If I then go and change to US Band while having WCDMA selected it indicates that it cannot change to that GSM/UMTS Band. Also interesting, If I stay on WCDMA and select Euro Band, no error, but of course all calls fail. I then tried to change to Japan Band, no error and no phone calls. Finally I am still on WCDMA and I switch to US Band and I get the error that indicates I cannot change to that band. So, I would be interested to know Alcaline if you see the same behavior on some of the other radios you have been trying to see they allow the switch to WCDMA / US Band combo.
Thanks

Can anyone else confirm this behavior on any of the other Radios out there?

I have the ability to tell my phone I am in the states, but it does nothing (default settings though)

Was the US version (WING200) of this phone ever released? Or has anyone gotten the EU version to work on any US 3G networks? Wondering about T-Mobile...

disable 3g/hsdpa - only edge possible?

hi guys,
i've googled a bit but didnt find what i was looking for.... i've been using an iphone for quite a while before switching to the diamond2 - on my iphone i was able to deactivate 3g/hsdpa and only use edge, which improved battery life by one third. is this possible with the diamond2 as well?
thanks in advance.

Yes, telephone keypad [dialer], menù, option, Band and you can choose GSM or WCDMA

i live in austria and as far as i'm informed there is only gsm, no wcdma? or do you mean to only select gsm, not umts networks? if so, i don't think that's possible, because i can only choose:
gsm (900+1800) + umts (900+2100)
gsm (1900+850) + umts (1900+850)
umts(2100+800)
tia

there s 2 drop down lists - choose the first - it should have a choice of auto / gsm / utms - the second drop down contains the frequency - leave this on auto

There is a very nice app that allows you to enable or disable 3G in the Comm-Manager

Desperatly need help getting 3G instead of E

Hi guys,
I brought my first xperia from my phone serivce provider, and it always had the "3g" symbol at the top. However, when my xperia broke, I had to buy another one and got one of ebay. Since I brought the new one, my phone always has the 3 on top. I'm currently using the firestorm valkyrie rom which as the htc interface. When I go to the data connections it says an option (3g) "change to gsm mode" and on is selected. Even when I toggle that, it still always has the E symbol. What do I need to do? I know my sim card is cabable of getting the 3g. But this is a real pain because every now and then my phone just doesnt receive service, so I constantly go onto the comm manager and then it seems to just click that there's service and shows 2-3 bars. Then all of a sudden again after a while there'll be no service. So I'm guessing that's because of the E thing. It shouldn't be my current location as I've never experienced this before.
Is there a setting I can go to to get the 3g symbol? Or a patch I might need for the phone?
Please help
Kindest regards.

You need to change while the connection is not active, I believe. Or... you got the Xperia version incompatible with your network... Or... the ROM is buggy, try another.

sorry, I need to change specificially what when the connection is not active? Say you mean, turn off my phone settings and not connect to the network and then adjust something? It is not the rom. and the seller on ebay has stated that it is a 3g phone - many others have brought it as well with no complaints.

3G settings on x1
Hi
For some reason your phone is only camping on the GSM network (G or E indication depending if your carrier provide GPRS or EDGE on the GSM) instead of the 3G network (which you have been using before).
In settings, communications you should be able to set "3G change to automode" to on,
When this is set your network provider will tell your phone to use the 3G as preffered network, but when coverage is not good enough it will drop you back to 2G (which has a better reach due to lower frequency band).
If it does not happen automatically there might be another setting that is wrong,
goto settings, all settings, personal (tab), Phone.. then choose the "band" tab (need to go to the left with the arrows) , then you have the dropdwn lists to set:
select you network type (need to set auto or wcdma to get 3G)
select your GSM/UMTS band (need to set 900+1800 for europe, 1900+850 for us, dont know who is using 2100+800)
once changed the phone will restart the phone part and search for your carrier in the right band.
good luck

Hi,
Thanks for your reply. I had changed the automode to on. But still had the E.
I went to the setings, and band tab, and i had selected:
Select your network type:
(blank)
Select your GSM/UMTS band:
Auto.
I changed the first oen to auto, and as for the last, here in Australia I'm with Tesltra which is 850 UMTS? I think I read online. Anyway it didn't have the option in there, so I went through them all but wouldnt get service at all except for the first: GSM (900+1800)+UMTS(2100+900). and Auto. I think my last experia might have had auto for all of those too. Anyway with those only two options working, I still get the E icon. Even tried setting aeroplane mode on and then off to see if it might register, but it didn't.

I see , Telstra is one of very few networks that use 850 for WCDMA so they might be using a different RADIO ROM than the rest of us
I saw in the thread below that there is a TELSTRA AUSTRALIA (1.03.841.8) R2AA008 version..
http://forum.xda-developers.com/showthread.php?t=477801&highlight=telstra
you probably need to flash that one to get the 3G working on telstra..
3 is using the normal 2100 so you could also try with their SIM just to check that there is nothing wrong with your hardware..

Sorry for the late reply.
I have realised that i'm in an area that doesn't support 3g. however my last xperia phone which I brought from telstra was the x1a, which had the next g network - hence I got the 3g symbol. However I have found that that I have the x1i, which doesn't list that network. I rang up telstra, and they transferred me to the sony erricson call centre, and they said you can try and do an update but it is not gaurenteed to get the next g service. I have already flashed a htc rom and don't particluarly want to change it back, unless i'm certain that I will get the next g service.
With the rom you have provided, do you think it will have the UMTS 850 band on there, and my x1i would be able to connect to it? I would have thought that it would be a hardware preference, not a software. In which case, even if I updated the rom because there is say no "chip" that allows for connecting to that band, it wont connec to it even though I may have selected the 850 UMTS band.
Sorry if that seems all over the place, but yeah... I'm not sure.
