How to get your Galaxy s working on 850MHz WCDMA

Im running an unlocked i9000 in Australia using Telstra's network which is 850MHz. After flashing some roms it was only using 2100 and even using the settings at the start of this forum wouldn't fix it (below)
1. on the key pad, type *#*#197328640#*#*
2. Select [1] Debug Screen
3. Select [8] Phone control
4. Select [7] Network control
5. Select [2] and selection
6. Select [2] WCDMA band []
7. Select [6] WCDMA 850
This seems to point to this being a software not hardware issue.
After lots of messing around i flashed a Samsung i897 Captivate ROM from AT&T which of course didnt boot then flashed another i9000 ROM minus the modem and now its all good. I set the phone to 850 only and had a look at basic info to confirm.
Here are the steps:
Flash your phone with Odin1.3 and I897UCJF7 found at samfirmware(.)com
boot phone (will show AT&T logo but wont boot)
Flash desired ROM WITHOUT modem part (also left out the csc part) im running CSC-I9000OXEJG1 although I dont think it makes any difference.
1. on the key pad, type *#*#197328640#*#*
2. Select [1] Debug Screen
3. Select [8] Phone control
4. Select [7] Network control
5. Select [2] band selection
6. Select [4] combi bands
7. Select [8] WCDMA 850
8. Hit the menu key and select back
9. Repeat step 8
6. Select [2] WCDMA band []
7. Select [6] WCDMA 850
8. Hit home key
on the debug menu you can select basic info and it will tell you if it has worked. Although 850 is the best band here and my phone defaults to it if your in a 2100/850 area you may need to test it in a 850 only area.

Just out of curiosity, which Galaxy S variant are you using? AFAIK the one sold by Optus doesn’t support 850Mhz ?? And Telstra has not yet released their Galaxy S

I am interested too, same situation, you sure it is connecting at 850Mhz 3g ?

*snip*
Nevermind.

Anyone else tried this?
I'm on stock ROM and although I've rooted I've never flashed anything yet so not confident without a step by step.

This was a Telstra one so with the default firmware it worked on Telstra but as soon as i flashed anything else it stopped working and presented exactly the same symptoms as a Europe version (which is what our rep said we had). I have tried every other combination of firmware and settings suggested and this is the only one that works. I'm technically minded so if somebody wants to post a how to on dumping a Telstra ROM I work for them and can get you guys the firmware.

So your i9000 from Telstra already has 850mhz support?
When I first read your post, I thought you had an international i9000 and somehow magically made it work on 850mhz 3g.

I'm totally confused.. are you folks saying that the Galaxy S has CDMA capability as well as 3g and HSPA??
One would think that would a huge feature which would have for sure been exploited by now.

Exactly my thoughts, but I have an open mind.
Would be nice if it worked, so I will certainly follow this thread.
I have been thinking of flashing the Bell modem to my Galaxy S to see
if I can improve my AT&T signal at my home, as it is bad.
Other areas, it is fine and so probably I have little chance of improving it,
but think I will try.
With the HD2, I was able to improve my AT&T signal by changing the Radio.
I don't get 3G, but don't care about that, since WiFi is readily available.

WCDMA is what UMTS/HSPA/HSDPA is called. It is not your run of the mill CDMA.

hang on im confused... you have a phone that isnt released yet, so you must work for telstra or know someone from telstra that was stupid enough to break the NDAs between samsung and telstra and give you their unreleased phone... yet you dont have access to the telstra rom and youre offering to reverse engineer the telstra rom on this forum?
youre treading on dangerous ground my friend. corporate security always finds out be warned.

The Phone has been out on Telstra as of today...and could be bought outside of a plan through telstra stores since friday.

really?
telstra didnt advertise that one very well... oh well their loss
im gonna have to go get me one of those. the hardware is different though. international i9000s dont have a 850 radio whereas Telstras one does. so its getting other peoples hopes up saying that 850 can be enabled when it cant be.

I was going to get one until i found out the price Telstra is selling it for.
But yeah this thread certainly got my hopes up

yeah youre better off buying a vibrant from the USA or Canada and flashing it with a telstra rom. save yourself $300.

Yes I work for Telstra had the phone for a week now, gotta have some perks yeh? The price of the phone outright it $879 as far as I know. My point is when I flash with a Europe ROM and try to enable 850 it seems enabled but doesn't work which is what people have been getting so far. When I flash the radio of a phone designed to work on an 850 phone it does work. Someone test it and find out take you 10 min to test it. If it doesn't work then that blows but if it does I know lots of people here would want to do this. PM me if the instructions are not clear.

Do not buy the US Vibrant. Only the Canadian one is an I9000 with the 850 band.

Okay, copy that. Makes more sense, but now what is all this about then? Me being on the Bell using the Bell I9000m am I missing a feature, is there something I can enable to make my network strength better. Those of us on Bell or Telus can attest that not having 2g sucks. The folks on Rogers get much better penetration of signal into buildings and such. Sure would be nice to fix that if possible but I have a feeling that I'm barking up the wrong tree...

I'm at work, so I can't test it right now.
While it would be cool if it does work (so I can switch back to NextG from Vodafone), I don't hold much hope at all of it working.
Bare in mind that a Telstra SIM does work in the Galaxy S, just not on 850mhz. I had to use my Telstra sim for the first few days before switching to Voda to make use of the 3G network. The Telstra sim only connects at old-school GSM speeds.
If nobody else tests it in the meantime, I'll try to give it a crack during the week. But I work 12 hour shifts, so may not have time.

^^ this. The bell i9000m is really an i9000 (international version). front facing camera and all.
I flashed an international rom (jm5) onto my Bell Vibrant - and was able to enable the 850mhz radio. With a little fiddling (a.k.a the steps in first post, just enable it in combi band first, then in wcdma menu), and making sure the 'wcdma only' setting was on.

Change HD2 frequency band

OK I have done some searching around on this topic and I'm finding a lot of mixed information. I'm currently on the Rogers network here in Canada and I managed to get my hands on an HD2 for next to nothing. So I jumped on the chance to have a "boot whatever the heck you want phone". However, while initially researching the phone I only quickly looked over the supported frequencies for the phone to ensure that I could use in on Rogers. Of course it will work as a phone just fine, however, it will not support 3g....apparently.
Started searching about for a way to change the phones frequency and some are saying it is possible to flash another radio for say the European version and some are saying that's not possible. I'm inclined to think it is not possible and that it is a hardware limitation. I figure that this is the best place to look for some real answers. Anyone have some insight into this matter? Oh and if it is a hardware issue and it can be changed....I'm not afraid to take the whole phone apart to try it. Ive done my share of tear downs on other phones....just for the heck of it.
Thanks in advance

only the telstra model will give you 3g on rogers.
hardware, and not changeable
yes you can change the radio (if youhave a tmous ((t mobile us)) then you need to be REAL careful which radio you flash) but changing radio has no effect on the bands.
this forum is for the regular hd2, the tmous (if that's what you have) can be found here
http://forum.xda-developers.com/forumdisplay.php?f=631

If you have the T-Mobile US version then you can use it on Wind Mobile here in Canada. This is what I'm doing and everything works great, including the 3g. I've loaded Android on it and I absolutely love my HD2!
Sent from my HTC HD2 using XDA App

I actually bought a Telstra (Montreal Fido user) because we don't have Wind here... Telstra works great. Got it off ebay from a nice aussie fellow. I wanted the Tmous one for the extra ROM space, but hey... As long as Android runs on it, I'm more than happy!

[Q] Milestone 2 (GSM) on At&T - 3G Works?

So, I was about to buy this phone and use it on At&t in the US, but as I was looking at the ebay listings, I noticed that some of them stated that It does not work GSM with at&t.
I'm not very tech savy, but I find hard to believe that such an advanced phone would have this problem. Can anybody that tested it, shine some light on this for me please?
Thank you

It has the hardware to support it but it's the software that verizon has locked down to not work with any other carrier in the USA
In normal gsm phones you simply need an unlock code for the phone to work with any other carrier then the one it's meant to work with but in this case even after you give the phone the unique code it still won't work with att or Tmobile in the USA so we are looking to see how to disable the lock on USA bands on the phone but it seems not many people have made much progress

Thanks for trying to help, but that is not what i'm asking
I know it works, but everybody says it doesn't work on 3G, just on EDGE.
here's the response I got from an ebay retailer
"This version will work on the AT&T GSM network, however, will not work on the 3G network, only edge.
Best regards,
Communication Telecom International "

AT&T uses 850Mhz and 1900Mhz for the 3G frequency bands and it does support it in the hardware as I was saying, its just that nothing at this point will work not even EDGE because the USA lock overrides anything AT&T uses.

You are confusing the Droid 2 Global with the Milestone 2. Two different phones here.

the milestone2 should have the right hardware to connect to att 3g sorry for the confusion

The Droid 2 Global and Droid Pro also have the hardware to support US GSM bands but it has been disabled in the radio. This is not software, so to speak, but rather hardware configuration.
If you know where to look you can fix this problem.

feel like sharing?

i think he is messing look at the username.

Don't hijack the thead!
OP asked about Milestone 2, not Droid 2 Globlal.
So - to address OP's question - yes - Milestone 2 currently on sale in most places is the EMEA model (Europe/Middle East/Asia), which has 900 and 2100 W-CDMA bands only.
Based on the official page from Motorola here, Milestone 2 A953 has a version with W-CDMA 850/1900/2100 MHz which are the bands used primarily in the Americas (850 and 1900) and Australia (850/2100). There was an article the phone is coming to Argentina before Christmas, so it may start showing up quite soon.
If you want US 3G support from Milestone 2, you have to wait for one of these to emerge. Sure enough it will not have any restrictions against US GSM/WCDMA operators (MCC 310) like the Droid 2 Global (currently) does.

I am not "messing". I cannot post external links of proof because I have too few posts.
I also do not wish to SPAM your forum out of respect for the rules.
Search for droidbandunlock on Twitter for more information.

thats sweet then I saw the video, I have a D2G and bought the phone for this purpose, where will the release be?

They inted to sell it as a servce. It definitely works...we were early testers and I have been trying to help them get the word out about it. These guys know what they are doing and what the value of this exploit is.

well sure but I'd like to know about it asap I've been stuck using this on wifi only :/
I'd pay about $10 for it

Those bast*rds!!! How dare they know what the value is and not give it away for free!!!
I am just kidding
People sell unlock codes all the time for like 15 bucks so should be no problem for people that have to pay for this exploit...wonder if it is the same one I found

This may not be the best thread to continue this discussion. My apologies for the hijack.
I am most interested in seeing what you have found, but from what little reading I have done in your threads it appears you are working in the system only and not modifying the radio.
If that is the case, then our exploit has nothing in common with yours.
Do you have any evidence of it working with US GSM bands on AT&T or T-Mobile?
Perhaps we should start another thread, but we will not be revealing the precise nature of our method for obvious reasons.
Our method makes no changes to the system and leaves no trace of itself anywhere that can be accessed on the device itself beyond the ability to use the US GSM bands.

sorry to interruput but i think this is the only way to talk to you unlocker but about what will the price be and where can we find more info about release dates and downloads etc.? i found you on twitter and asked a few questions but there still isnt much info

I have to modify system because in my ROM (Fission) the packages that handle sim card functions do not work without some "blur" components so thus the need to modify my system
I have pics and a vid ready to go for when I was going to sell my service. I am not trying to nor am I going to compete with you guys or from TBH. P3Droid and Gweedo have been nothing but really friendly with me and to be honest; I would rather not deal with the headaches that come with selling a service on this forum and/or many others. I already went through and going through hell for the way I handle Fission ROM Manager and really don't want any more of that crap...I would rather continue dev work on the ROMs and some other apps I have been working on
I won't get into how my method works for the same reasons that are very clear too but if you want to discuss anything in private feel free to message me or hit me up on Gtalk.
Did you guys release your method yet? If not when do you plan on doing so? I would like to prepare Fission for users who will need to unlock or do use their SIM cards...

Thanks Angdroid for ur hard work. Been following u for some time, hopefully u can release SIM package for D2G Fission soon.

Could anyone running Fission ROM try to switch to GSM mode from *#*#4636#*#* menu? I know you can switch to GSM from there on the original ROM without having to go to settings/wireless/networks/etc As it is standard Android tool, maybe that could be used to switch between the two radios until AngDroid figures out how to make it nice. Hope it works though.

[Q] HTC Wildfire + Radio image question

Hi
I have recently purchased an HTC Wildfire A3335. For those of you don't know, this is a special version of the Wildfire which has a UMTS 850/2100 Radio. Anyway this phone seems only to be available heavily branded through an Australian operator, Telstra.
Due to the hideousness of the branding, I naturally wanted to get rid of it. This was pretty easy-- Cool-- I now have an unbranded wildfire A3335.
Now, when it was flashing (using an HTC RUU exe) I noticed that it was "Reflashing the radio". I freaked out. I know this phone has a special radio in it and of course the unbranded RUU is for the 900/2100 UMTS version (A3333).
So as expected the phone has lost its very special 850MHz UMTS and now only works at 2100MHz (I doubt the phone has suddenly gained the ability to use 900MHz UMTS as it has the wrong chips in it)
The Radio image for this phone is available inside the Telstra RUU on shipped-roms.
My question. Is it possible to extract the radio image out of that and flash it in with the rest of the unbranded system? And hopefully get my 850MHz UMTS back. Currently it appears that the answer to this is no due to the lack of signing?
Current HBOOT: 0.80-0007
Current ROM HTC Standard (Eclair 2.1) 1.37

You can't lose or gain any frequencies by flashing the radio, it's in the hardware...

OK firstly, I did lose 850MHz when flashing the standard image on, so you definitely can lose (but never gain)
The Radio PHY in the phone will be split into two parts, the 2100MHz part and the 850MHz part (or a 900MHz part).
So on the normal wildfire radio image, there's a driver which is likely compiled to drive a 2100/900 radio, and when we run that image on the 2100/850 phone, 2100 remains working because this part of the chip is identical. The 850MHz part dies completely because this driver is not expecting it.
I know how lazy microcode developers are - it's very rare for anyone to go to the effort to make microcode images to support two subtley different chips, instead they will compile two versions of the microcode with subtle changes for each one. Only one bit in a register need be set wrong and the whole lot comes crashing down!
Now there could be a scenario where the radio is a 100% hardware solution, and there is no microcode for the UMTS radio, in which case there's a better chance that having the wrong radio image is not an issue, as the chips themselves are more autonomous. But then - What does the radio image do? In my experience of working with 802.11 Radio PHYs: Not likely. These chips are almost always highly software driven and must be running the correct code to fully function.

Okay so it looks like I just became the "expert" on this one and can now answer my own question.
It is possible to restore the original Telstra radio image, without rebranding the phone using the Telstra RUU.
This is what I did:
1) Download Telstra RUU from shipped-roms
2) Extract radio.img using this process: http://lukasz.szmit.eu/2010/04/extracting-rom-files-from-htc-android.html
3) Repacked radio.img into an update.zip
4) Signed update.zip using http://android.modaco.com/content/software/313829/pc-tool-zip-signer-v1-1/#entry1348449
5) Manually added com/google/android directory into META-INF directory in ZIP file (Copied from someone else's radio image.
6) Flashed image using clockworkmod "update sdcard" menu (unrevoked had already installed clockworkmod)
Done! I've got my 850MHz back again!
I've included the update.zip with the Telstra wildfire radio image here: http://xpander.inaxeon.com/data/files/update.zip
It's interesting looking around the various forums, I think a lot of people have been willy nilly flashing the wrong radios onto their special 850MHz devices then not fully understanding why their phones are without 3G coverage a lot of the time. Oops!

Interesting, last time I checked the radios were identical. I must have missed something. I'll try cross flashing the Telstra A3335 radio on the 900/2100mhz A3333 and see what happens, 3G up here in Canada runs on 850/1900, getting 3G on one of the 2 bands would be nice.
Edit: It's the same as the other radio of the same version 13.45.55.24/3.35.15.31 , did a checksum against the HK_CHT one (cid HTC__622, a A3333)
Maybe the "H" in the version have something to do with the frequencies? ie: Radio_13.55.55.24H_3.35.20.10 from the Froyo WWE rom.

Did you not read my second message!
Unless you have an A3335 flashing the Telstra radio is going to make your phone even worse!
The full solution for 850MHz UMTS requires:
A) The right hardware: (Wildfire A3335)
B) With the right software: The Telstra "Radio_13.45.55.24_3.35.15.31" is currently the only radio image in existance which can correctly drive the A3335, and in no circumstances should be flashed on anything other than the A3335!
Likewise - If you have an A3333
Do not flash the Telstra radio image on it, as it is the wrong code. You'll end up losing your 900MHz UMTS in the process (OK so that doesn't matter too much in Canada)
To say it even simpler:
Every radio image except Telstra is OK for use on the A3333
The A3335 must be running the Telstra radio image
Telstra Radio_13.45.55.24_3.35.15.31 is a special piece of software for a special piece of hardware!
EDIT: Kwen has checksumed the A3333 and A3335 images of Radio_13.45.55.24_3.35.15.31 and found them to be identical. This confirms that this paticular version supports both 850/2100 and 900/2100 phones, whilist newer versions do not. See more recent posts.

i have a telstra wildfire which i have wildpuzzle v.08 running on, with putting a new rom on i would presume i have a different radio, am i correct. yet i can get 3g and wcdma/hsdpa no problems. or am i confusing myself

Thanks for this. I'm going to keep the update.zip safe just incase.
I've just imported an A3335 to use on the Telecom XT network here in NZ and I just flashed it with DK's rom (shame that I'm still stuck with the Telstra splash screen).
Although 850MHz is the primary band Telecom uses for their network they also have 2100MHz fallback in my location, so I'm not 100% sure what band the phone is running on.
Is there a service menu or an app on the marketplace I can use to check the band for peace of mind?
Thanks again.

It made no difference, couldn't tell if I lost the 900Mhz, couldn't get the 850Mhz for sure.
I tried playing in the Field test menu to switch between GSM Only to WCDMA Prefered/Only and the Band selection menu and completly lost access to GSM, it was stuck on WCDMA Only, had to do a nand restore (nothing to do with the radio version)
I'm not sure if the Radio_13.45.55.24_3.35.15.31 is exclusive to the A3335, most of the roms uses it:
Vodafone SPA
H3G ITA
HTC WWE
HTC Asia India
HTC Asia WWE
HTC Asia HK CHT (that's my phone and it'ss a A3333)
H3G UK
HTC Asia TW
HTC FRA Bouygues
HTC WWE Tesco
Vodafone DE
How did you find out which band your Wildfire was using? (or did you just not have any signal?)

Pretty easy. My operator has no GSM (at all) or 2100MHz sites where this phone is most commonly used. When the alternate radio was flashed on, the phone flat out lost all connectivity to the network. It only returned when the phone was driven to a place known to have 2100MHz coverage. That was a pretty damning and poignant confirmation.
About the versions of the Radio, When I was first considering flashing the RUU I had already been concerned about the radio image and checked the version. I saw that it was used in other A3333 targetted images so assumed that the radio images were not phone specific. Turns out I was wrong.
What would be interesting is to checksum compare Radio_13.45.55.24_3.35.15.31 from Telstra vs. other images. If they are identical, then we know that this particular version supports both style of radios, in which case it is safe for both versions. The reason I've always been qualifying that version "Telstra" is in the fear that they are different despite the identical version number.
Short of actually being a hard core hacker or HTC engineer, It's a bit hard to tell really. All one can really do is share their experiences.

I can confirm thier identical checksum (I checked against another one - not all the versions lol)

another special version of the WF
Hey man, I have a wildfire which runs on these frequencies GSM/GPRS/EDGE: 850/900/1800/1900 MHz and HSPA/WCDMA 850/1900 MHz.
I was going to flash a stock RUU till I read your post, so I wanted to thank you for saving my precious 3g!

Hey man, I have a wildfire which runs on these frequencies GSM/GPRS/EDGE: 850/900/1800/1900 MHz and HSPA/WCDMA 850/1900 MHz.

What the heck model is that!
I understand HTC may have a provision for 850/1900 (Model A3334) But as far as I knew that never went into production due to lack of interest from operators. Or is this a fruity variant of one of the new Wildfire S models?
EDIT: As bought to my attention by juanchotolas - it appears that the 850/1900 A3334? (Awaiting confirmation of the exact model number) may exist after all. It leads a low key existance in Latin America sold under an obfuscated difficult-to-google-for name. It's called "Desire A" but it's really a Wildfire. Here's the little beasty: http://www.htc.com/la/product/htc-desire-a/overview.html

Thanks for this. I'm going to keep the update.zip safe just incase.
I've just imported an A3335 to use on the Telecom XT network here in NZ and I just flashed it with DK's rom (shame that I'm still stuck with the Telstra splash screen).
Although 850MHz is the primary band Telecom uses for their network they also have 2100MHz fallback in my location, so I'm not 100% sure what band the phone is running on.
Is there a service menu or an app on the marketplace I can use to check the band for peace of mind?
Thanks again.

I've spent many an hour searching for such an application and one does not seem to exist. Post one here if you find one.
The phone I've been working on was a present for my sister is also used on Telecom XT, I bought it due to the spectacularly average range of phones available at the time through Leading Edge, hence my burning desire to remove the Telstra branding.
You can imagine how incredibly silly I felt when it arrived, she powered it up and it couldn't connect to XT. The thing that's made it extra frustrating is that I live in the UK and was originally working on the phone from here. The UK only has 2100MHz UMTS so couldn't test properly before posting. I've had to do all of this reflashing over the phone and with remote access from the other side of the planet!
Anyway, If you flash the most recent 2.1 RUU (not 2.2) then reflash the radio I posted, you can achieve a fully unbranded A3335 on XT.
You're fortunate to have 850MHz UMTS over there, No one offers sub 1GHz 3G here and it stinks! I used XT for a few weeks while I was back for Xmas and it was an amazing service (If you can get over the cost). You can't have service like that on any network here. Green with envy.

I was attracted to DK's rom because he made mention that the radio was left untouched (or optional to flash). So I'm fairly certain I'm running the original Telstra radio. I just can't be certain.
Would like to flash the 2.1 RUU and then back to DK again to get rid of the splash screen but for me, all that risk isn't worth the vanity. Like you, the phone isn't mine. It was bought for someone else but I'm responsible for its up-keep.

I'm all about the vanity! I even replaced its plasticwork to remove the logos from the case and posted it in a London issue Wildfire box (had one spare). There is not a single Telstra logo anywhere on this puppy! I think I'd be pretty comfortable in assuming that it's the only fully software/physically unbranded unit in the country- pretty satisfied with that!
The ROM and the Radio are two different components. You should never overwrite a radio by flashing just a ROM.
There's only two (maybe 3) ways you'll ever end up overwriting the Radio on an HTC phone:
1) Flashing an HTC RUU
2) Explicitly flashing a radio update with Clockworkmod.
3) It is theoretically possible for ROMs to include Radio updates but I've never seen a third party ROM contain a radio image. With maybe a small number of exceptions, ROM developers generally aren't going to risk deploying radios with their releases.
Of course you can easily find out by examining the contents of the META-INF/com/google/android/update-script file in the ZIP archive. If there's any mention of "Radio" in there then avoid it on exotic models like A3335

-strike off. the radio build might be different - there might be radios with partial coverage-

This is the "Latin-american" Wildfire it is called Desire A (but we know it's a wildfire...) Here is the translated link so you can check it out http://translate.google.com/transla...la/product/htc-desire-a/overview.html&act=url

Defy MB525 has all frequencies?

I did a search, but nothing found for my question. Does the MB525 support all frequencies? I have one I bought new when they came out for T-Mobile US, and I know it needs the 1700 frequency for 3/4G speeds, but I'm looking to get another one, but all the ones I see don't have that frequency listed. My question is do all MB525s support all frequencies? I'm rooted on my original one, and I've used the baseband switcher from CM7, and I see I can select all different "world" frequencies, so If I buy one that is say 900/2100 on the box, can I root, and use the baseband switcher to choose 1700 for T-Mobile? Or would I be stuck on 2G forever with it?

Yeah it should work, although I'm not 100% sure

It works out of the box.
I picked a new one up from Ebay. It said it was unlocked, and supported all frequencies. I put my sim card in, set T-Mo APN, and I got 3G out of the box. No need for the baseband switcher. I'm happy now. I got me a brand new Defy. I didn't even know they are still being made (Or at least as recent as mine). I thought since it's over a two year old phone, and there is already the Defy+ and Defy Mini, that the good old original Defy was done production. Mine was just made 3/2012 by the manufacturing date on it. Great news for anyone looking to keep this phone going in case yours is starting to breakdown. There are a lot of new ones out there. It's all black and unbranded, and comes with 2.2.2. I'll be keeping my original one just in case, and I may pick some more up at the price I paid. US $168.00 shipped.

Yes, with the baseband switcher you can select every frequency.
So its Quadband
Wish they would have had that for old Nokia symbian phones

My carrier uses 900/1800 baseband. I tickled through all regions and carriers and didn't find 900/1800. The closest option is 900/2100. How to add 900/1800 baseband to baseband selector?

Then perhaps you can use either 3g or 2g, not both depending on which baseband you select

I'm not sure what version of the Baseband Switcher you are using, but the one I have doesn't show that frequency at all, and I can't find it on any other ones. Here is the link to the one I have. Maybe you can contact the Dev to see if 900/1800 can be added. http://forum.xda-developers.com/showthread.php?t=1052745
EDIT - Just to be clear the OP in that thread does say new ones can be added. This is from the thread: "If anybody needs other basebands included, copy the folder /system/etc/motorola/bp_nvm_default from your Defy, zip it, post a zip here and write down out of wich rom it is and for which country it is.
If anybody wants to add new Languages, PM me the translationlist + what Language it is."
Good luck.

I use only 2g network. My phone 3g baseband is not supported by my carrier. According to my carrier website it uses GSM800/1900 baseband.
