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.

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?
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...
Hi,
I have a huawei ideos (older non X6 version) and supposedly it is unlocked. It works with 2g/edge. It does not work with 3g. I have looked for APN information and the info downloaded to the phone when I connected to network is identical to what is listed on the net.
tmobile docs url not allowed
i had to add the MMSC setting since it was not there as listed in step 12.
Things which are odd. When choosing access network, it does not say T-mobile 3G. It only says T-mobile 2g, Att 2g and Att 3g. According to the net this phone supports the frequencies for tmobile.
gsm link for u8150 not allowed.

And

Not sure if HSPDA spec is same as HSPA though.
I did the trick where you enter #*#*4636*#*#* and checked phone settings. I changed to GSM auto (PRL). I also tried to hit menu and select radio band, but it pulls up an empty "Set GSM/UMTS Band" dialog. There is nothing to select.
I guess my question is, does this phone support 3G for t-mobile and if so, what setting am I missing?
thanks in advance.
John
Wrong phone forum this is likely to get frozen.
hi
if u look in the android general forum i did see a few threads for u8150
u have a better chance of getting ur answer their
goodluck
thanks
Thanks, I moved the question to general forum.
