Dunno if it makes any use, but an HK extend rom cab file will enable the band selection on yr phone device (what it did just put some registry setting on HKLM/Software/OEM/PhonePH.

I am living in North America which I can only test 1900
I found both 7 and 4 works for me (fail if using 1,2 or 3)
People in other GSM region (especially ppl in LA where 850 is available could try the missing 5 & 6 value) can try if other GSM region works for U.
7 = automatic
1 = 900mzh
2 = 1800mzh
3 = 900 / 1800mzh
4 = 1900mzh
5 and 6 seem to act like auto to me. I have both 850 and 1900 coverages and I am not seeing any differences with those 2 settings. They both act like the auto or 1900.
HI Everybody!!!
I have created one more setting under the value 5, as well I have changed showItem value from 5 to 6, but still the BAND page rejected to show all GSM bands I have. As a result I have deleted 900/1800 and putted 850 with value 5. Have no idea if it works or no, cos I am living in Europe, but now my BAND page looks very cool
WELCOME NEW i-mate JAM Pro 850/900/1800/1900 !!!
PS It will be nice if some one could really check the values 5,6,8,9
Thanx to jackleung for this post,
Good luck…
For some reason I can only see the 900 and 1900 band in my band select page. I have previously applied the .cab file and now I manually editted the registry again, but the band select page still only shows 2 bands, 900 and 1900. Does anyone have a solution?

How can one actually tell what band the JAM is currently communicating on? I was sure it's not a firmware or software setting and more likely in the hardware of the JAM, so it's kinda like relabeling your gear shift numbers or adding a number to it in your car - I don't think it's going to add any more functionality to your device.
Surely if the unit was a true quad-band in hardware, they would have supported and advertised that.

Just because many of us not living in 850mzh area and that's why we need someone who does to try it. But it looks the orginal value from the cab file really does what it declared.
Someone should give this a try. There's a possible way to try it. If you've got a PM10A (without the 850 support), follow the guidlines in this thread, select 850 as your band, reboot and use the program mentioned before to see what cell your operating on.
Then just look up the cell and see wether or not it's an 850. It would be awesome if it were.

You're absolutely correct. All this does is enable a page that shows the 850 band. It has been hidden otherwise to stop any confusion by the end user. IT TAKES A HARDWARE CHANGE. The radio must be tuned to receive the 850 band. No amount of software tweaking is going to change that....sorry.

After to have modified the GSM Band Selection I don't have the confirmation of my choice. Wich is the mean of checking that?
please anyone can re-upload the cab file. I cannot find it on the xda ftp site. please please and thanks in advance

Hey folks,
Is there a utility/hack that allows you to change the GSM band from 900/1800 to just search the 1900 band? Since upping to 1.72 my radio always locks onto the 900 band and stays there for ages before locking onto my operator (on the 1900 band). I have to have at least 80% signal level. I know that 900 generally is a stronger signal (the other operator is always at least 10-20% over my operator), so thats why [note: I cannot roam with the other operator].. I know the new iPaq seems to have a band select, and my Treo 600 does too....
HTC do you have a util?
Any help greatly appreciated.

i really doubt that HTC hang around this site you i think that
any questions you want to aim at HTC have to be mailed to them
Try this: go to phone, tools, options, network, network selection and put it in Manual, select your network and OK.
Tell us if it works well thus.
If it dont work, you can install old radio version.
Thanks folks for the replies.. That's actually how I have it set now (manual on my operator), but for some reason when you turn the radio on it locks on to the 900 band and just sits there.. If I walk around until a strong enough signal is obtained from my operator it'll lock on; but as you can imagine this is really annoying.
Thanks again for your pointers. If I find anything out I'll let you know, as I've also shot an e-mail to Carrier Devices; and will shoot something directly at HTC.
I may also drop down to Radio 1.10; but I hate having to re-install all my software again..
You can make backup, install old radio version and make restore.
I am planning on going to a GSM 1800 country soon but I only have GSM 900 & 1900 (what i'm on now) listed as choices. Is that because of my current SIM card or is there a problem with my phone?
Thanks,
Daniel
Here a file to enable the band selection.
How do I run this?
It worked-
Thanks!!
I go to the States in August. Work the Magician in the USA ?
Thanks
Depends but most probably:
If you are going to be roaming with your current SIM card then find out which network you will be roaming on- if it's T-Mobile you will be fine because all the Magicians can work on he 1900mhz band- which T-mobile is. Cingular/ATT mostly is 1900mhz also but some rural areas operate on the 850mhz band- either way you should be fine, but find out who's service you will be on to be sure.

Thanks !
I use Proximus from belgium.
by the way, how u know gsm 1800 band missing? how u check it?
in the phone: Tools | Options and the tab Band is missing.
I have the band option, but I can only choose:
GSM 900 (europe)
GSM 1900 (North America)

Hi All,
Currently released version of Samsung Omnia i900 does not support UMTS 850/1900, which are north american 3G frequencies, according to official Samsung documentation, as well as FCC approval docs. However it has been recently established the radio chip does support those frequencies, and they are locked in the firmware only. Here is the evidence to support this claim:
This is the official FCC documentation for i900 certification:
https://fjallfoss.fcc.gov/oetcf/eas...me=N&application_id=476604&fcc_id='A3LSGHI900
On the page 4 of the "Internal Photos" document you can clearly identify the radio chip - it's Qualcomm RTR6285 and according to Qualcomm:
"Support for Eight UMTS Bands, Four EGPRS Bands, Triple-Band Receive Diversity and GPS Integrated into Power-Optimized RTR6285 Device": http://www.qualcomm.com/news/releases/2006/060213_worlds_first_single.html
So, it's only as matter of unlocking those frequencies in the current firmware. Samsung made our job a little easier, by recently making a public release of new ROM with updated firmware, so we won't have to dump it ourselves: http://www.samsungmobile.com/promotion/omnia/sg/sub02_xp.jsp#
I have limited free time and limited experience with reversing PDA firmware, to be able to achieve this by myself - please help.
I just got an Omnia and sometimes it hits the 3g network so i am sure that the firmware is there but it is locked.

more details please - where are you at? what network/carrier do you mean? do you really see 3G icon and experience fast browsing/download? what is the firmware version on your Omnia? (Settings -> System ->Version)
AT&T.I have it from Singapore.PDA:i900DXHH3/DZHH3.As i mentioned it hits 3g for a minute or so and then it goes back to edge
man i sure hope this issue gets fixed!

a US model for the Samsung Omnia is coming to the US in October via AT&T. Look for the Samsung Mirage.

AllTheWay I started this thread to solve the problem for people in US,who already have Singapore/European Omnia, the i900. It's a well known fact Mirage hits AT&T on October 21st, but it doesn't help us one bit. Unless of course, you're willing to dump the ROM from i907, reverse it and replace the i900's radio with the one from i907 with all supported UMTS frequencies unlocked
I wish somebody could help us out on this issue, I dont know enough about rom editing to be of use ;(
besides, i think the 907 is already available but not branded to at&t: http://www.celluloco.com/samsung-i907-omnia-8gb-us-3g-support-version-hsdpa850-1900-e-pr-1873.html
any update of this thread?
HTC Diamond users with US 3G - please help
I'm starting to believe it might actually be possible to tweak existing radio firmware to unlock UMTS 850/1900Mhz bands using already embedded secret debug menu from Samsung developers, rather than having to dump it, reverse it, patch and flash back. Here is the secret code to access Root Debug Menu on Omnia: *#197328640#
Option #4 "UMTS rf nv" has sub-option "umts rf nv write", which I think allows to modify the active UMTS bands in the radio. Assuming we have that set correctly, option #9 "Common" from the same Root Debug Menu has sub-option #5 "WCDMA Set Channel", which allows to specify downlink channel range.
Here is my idea: some devices, such as HTC Diamond with US 3G enabled radio, have the same Qualcomm chip as Omnia, and run the same WM 6.1 OS. So,
I'm thinking it's worth a shot if someone with US enabled HTC Diamond provided us with settings from his device for those 2 configurable menus I just mentioned. If you backup your own settings, so you could restore them if it doesn't work - I think trying settings from another device will not fry the radio, worst case scenario transceiver will just shut down and be offline until settings are restored.
This would be great.... Iv'e been dieing to get 3g in the usa with the omnia.... Can anyone help with this?
Any updates on this? Would be nice. Especially now since we know omnia isn't coming to ATT as i907
If possible i will donate to the guy that dicover how to enable!
It may be easier to copy the setting from an I907 Epix. That has almost identical hardware and it is ATT + Samsung + Tri Band UMTS.
When I try writing the WCDMA channel it says "That value is wrong".
Also, I can only set one number, so I assume that they want me to set one in the listed range which is WCDMA2100.
Here are the bands:
http://en.wikipedia.org/wiki/UMTS_frequency_bands
Oddly, the Channels currently set stretch a few beyond the range cited on Wiki for WCDMA 2100. They start on the same channel.
Another oddity is that there is no uplink channel. I suppose that people just use Edge for this? Does the I907 do HSUPA?
well...
i'm living in ISRAEL,
and we have GSM network but we also have another cellular company that work with "UMTS 2100/850" band..
i'm working well on 3G with the 2100 band (my onmina have only UMTS/WCDMA 2100 only without 850 also..)
i will be happy to open if it's possible the UMTS/WCDMA 850 also.. so i'll have both 2100 + 850 on WCDM/UMTS (not GSM) freq...
but i'm not shure it's possible to open what ever you like.. anyway i'll try to ask our guys (at my cellular company i'm working at) about this freq stuff...
hope this thread will bring us good information..
also, just know.. my job is with Cellular phones.. and we have "for Testing" Omnia phone with WCDMA/UMTS 2100/850 bands..
but i don't know how i can download the firmware to my pc and try to use it on my omnia back...
if anyone know how i can "take-out" the firmware explane to me and i'll try to do it....

the Version says

as i think.. it's diffrent model.. I900L this "L" model.. not like ours phones... (i think, it's looks exactly the same!)
i don't think the ROM will chane the bands anyway..
anyway as you asked me to do.. when i'm doing the *#2263# code
i'm getting diffrent menu then our Omnias..
i'm getting 3 options that one of them it's "WCDMA Band Select" and in there you have ALL the UMTS bands and there is "Automatic" option.. what says this phone open to all kind of UMTS networks............ (including GSM also..)

i hope there are more guys who have this I900L to share the rom with us..
anyway you remmeber the code that you can change the phone settings buy country?
the main code is (type it from the dailer) *#1546792*#
and the password for section "2 - Preconfiguration" is *#81230*#
it's looks like if we will have the code for the "Internal" section, mabe we will find something in there ?!?!
if we will change to another country.. like Austrlia or something.. the bands will change also? what you guys think?

I bought an European Optimus 7 and it shows on the box "WCDMA 900/1900/2100, GSM850/900/1800/1900"
There's any way to put this phone to work on 3G WCDMA 850 networks at full speed?
Thanks
I own a Telus version of Optimus 7. My phone has the 900 3G band on it. I will tell you how to check whether your modem supports 850 or not. First, you open up the dialer and enter ##634#. This will install the MFG app, that will be accessible through your app list. The password that it asks is 277634#*#. Now you have access to the manufacturer test/setting menu. Proceed to the Engineer Menu, and then Modem Setting, followed by Band setting. There, you should see all the bands that are available, and WCMDA basically means UTMS or 3G. If you have the 850 band, it should be available in this menu. There are two other things you need to do before gaining access to this band, if available. But in order for me to continue, I need to know which carrier you plan to use this phone on. I am going to assume you want to use this in North America and you have already unlocked it. Let me know, and I shall help you further on making your phone functional for a 3G connection. BTW, I am typing this on my Optimus 7...the keyboard is seriously great, and if it wasn't for the loose buttons, I would have absolutely no regret over my purchase.
Thanks.
I saw here, there are these options available:
1.Automatic
2.WCDMA Only
3.GSM Only
4.WCDMA 850
5.WCDMA 1900
6.WCDMA 2100
7.GSM 850
8.GSM 900
9.GSM 1800
10.GSM 1900
11.WCDMA 900
Sorry for picking up this old thread again but there is no final answer on this.
The point is that I'm having the same problem, I have a european E900 and I can see the WCDMA 850 in the MFG settings. So is this working?
I'm going to Thailand next week and wanted to use True Move 3G which is on 850 Mhz.
Ok, just for the record - I am in Thailand now and the 850Mhz 3G Network from True Move is not working on the European E900.
Hope this helps for those who were looking for this answer.
Ok guys I don't want to take credit for any of this, the credits for this discovery goes to a captivate user in USA named shoman94. Here's his post.
I'm just reporting it here so a lot of canadian galaxy s users (I9000m) will save some search. The method to enable this frequencies is pretty simple but you need to have the recovery 2e version not the 3e that comes on UGJL2 firmware version from Bell. So if you still on stock firmware and want to play arround with modem version to see if you can find a better HSPA+ connection or a better GPS, I recommend you flash the last Speedmod Kernel via odin so you have clockworkmod recovery and the ability to apply update trought zip file not signed.
The method goes like this and it is good for I9000M / I9000T. (Might not work for I9000B as there is a tv tuner antenna so the modem firmware must be different and will not work for I9000 due to hardware limitation)
You need to have a modem that comes with 850 mhz enable (UGJL2, TLJL3, UGJK3, UGJK4, UGKC1). So if it's not your case just flash one of these modem first.
Put your phone on 850 mhz only mode. To do this just dial *#2263# in samsung dialer to enter the band selection utility. Enter menu [2] WCDMA Band en press on [5] WCDMA 850 (FDD V) and it should tell you W850 Only.
(Optional) You can dial *#0011# in samsung dialer to verify that you phone is realy using 850 band.
Reboot in recovery and update your modem with BVJJPD or BVJJPG version and reboot into android
(Optional) You can dial *#0011# in samsung dialer to verify that you phone is realy using 850 band.
Reboot into recovery and update your modem with the version of you choice (XXJVK or ZSJPG or XXJQ1 or BUJS1 or XXJVE etc) and reboot phone to android
Repeat step 2 and 3 and you should have network connection on 850 only. If it's not the case then you miss something and need to start again from step 1
If everything is good dial *#2263# again to reanable all the other fequencies so your phone can chose the strongest one depending on where you are. To do so select line [1] AUTOMATIC and it should said Select GSM & WCDMA All Bands. Then touch you optical menu button and hit back. Select Line [4] COMBI BANDS and click on the only one without asterisk ([8] WCDMA 850 (FDD V)).
Enjoy any modem version with 850 Mhz enable
Here a link to download the modem needed in step 1 and 4. There is also this site wich is good to find any of the i9000 modem version. Ironically they put UGJL2 modem under captivate folder even if it's use for I9000m.
Mod : It would be nice to have it pinned or at least added to the list of How to's and Guide.

Could not say as I haven't tried GB yet. But If you can install zip from sdcard in recovery I think it will work. This would need confirmation from other user but I'm currently using JVK modem with JS8 (2.2.1) so the other way arround should work too but I can't confirm. Make a complete backup with clockworkmod (data + system) so if it doesn't work you could just restore the system partition and everything will be fine.
could you attach the necessary modem files to your first post? or maybe a link to them
will help make it stickyable!

In theory your process should work. However, I may be doing something wrong, but the gingerbread boot loader does not allow older-CWM flashing of the modem files I have found. If there is a kernel that allows flashing of older CWM files, or if I can find the .bin files of the BVJJPD or BVJJPG so that I can flash them with Odin, it should most likely work.
At this time though, I can tell you that flashing a Froyo modem such as UGJK4 on JVK/B Gingerbread works. This is the configuration I'm running right now, and my 850 MHz band seems fully operational.
pardon the noob question but I'm on a local carrier (GCI in Alaska) and my phone doesn't get 3G when I travel to areas where it exists (I'm rural). I think they want to charge for adding 3G, even though it exists only when traveling.
I found a reference how to enable it:
androidforums.com/samsung-galaxy-s/258859-how-enable-850mhz-3g-network-frequency-your-samsung-i9000-galaxy-s.html
but I get an error saying the selection doesn't exist when trying to choose that 850mhz.
My carrier says it isn't enabled on SIM card. Am I S.O.L.? They have a Blackberry Plan for $30/month that says includes 3G, they have a $30 Android Smartphone plan that doesn't mention it either way, and then their basic $15 data plan I think doesn't mention it except they have a 3G option for $5 extra. Otherwise I only get Edge.
I've rooted the phone to install a couple things but haven't yet flashed any new firmware - it is buggy as heck (crashes a lot) so I'm reading the forums here - it is on baseband version XXJP2, thinking I may have to try something. Saw this thread and wondered if it would be of use to me.
thanks for patience, JD

My carrier says it isn't enabled on SIM card. Am I S.O.L.? They have a Blackberry Plan for $30/month that says includes 3G, they have a $30 Android Smartphone plan that doesn't mention it either way, and then their basic $15 data plan I think doesn't mention it except they have a 3G option for $5 extra. Otherwise I only get Edge.
I've rooted the phone to install a couple things but haven't yet flashed any new firmware - it is buggy as heck (crashes a lot) so I'm reading the forums here - it is on baseband version XXJP2, thinking I may have to try something. Saw this thread and wondered if it would be of use to me.
thanks for patience, JD

First you need to have a modem version that supports 850 Mhz to be able to enable it (i.e. UGJL2, TLJL3, UGJK3, UGJK4, UGKC1). Once you have one of these modem you might have to add the 850 band in combi bands screen before you can actually select "only 850" in WCDMA screen. If you have JP2 modem you will be able to enable 850 only mode but you won't get any reception.
I wish someone could figure out what this procedure actually does, there must be some specific difference (in settings files?) after the phone has gone through this procedure. That difference could potentially then be applied directly.
I have a slight interest in trying the newer modems but can't be bothered to jump through this many hoops.

Once you have the file on your phone it take only 2 reboot time. 10 min max. It's not that hard and I've explained every little details so every one could follow these steps. Plus you only need to do it the first time you flash a modem that's not supposed to support 850. After that you can swich to any modem and still have 850 working.
aftter doing steps 1,2 and 3 i get no reception (if i go back to 2100 mhz, i get the signal back).
thx anyway.
To the OP, you might want to mention that this will NOT enable 850mhz on phones that do not have the hardware support!
I have enabled 850 on jvk and jvb modems with this method, they work fine with js8 froyo.

All the i9000 have the same hardware, it's just that software is not there on some version. Do you really think samsung will have made a chip that support 850/900/1900/2100 and another one with only 900/1900/2100. Complete waste of time to change the assembling line plus there is report of people with i9000 having reception on 850 band with this method.

If your operator uses 2100 frequencies it might not be using 850 too. Here in north america, operators use 850 and 1900 frequencie so we need to have both available but if your operator doesn't broadcast on 850 then you wont have any network!! My guess is that your operator uses 2100/900 or 2100/1900 frequencies or maybe they only have one. Where are you from?

Sorry sir, but you are completely wrong.
Samsung has a variety of modem chipsets used in their Galaxy S phones worldwide.
In the USA, Captivate has 850/1900/2100. Vibrant has 1700/1900/2100.
Elsewhere I believe the regular I9000 has 900/1900/2100 and the I9000M has 850/1900/2100.
There is not just one model and there is no way to activate a band on a phone whose modem is not compatible.
I wish all phones just had all bands (Nokia and Apple do the best job of this) but we are not there yet unfortunately. I too would think it would be more economical, but there could be other reasons like carrier lock in (i.e. in the US you can't switch a Vibrant to AT&T or a Captivate to T-Mobile without loosing 3G coverage).

i have checked it, my operator support 850 mhz.
i guess its a hardware thing wich i cant change.

Who's your operator? I'm wondering because 850/2100 combination is pretty uncommon.

That's why I said I9000 refering to i9000/i9000m/i9000t. The galaxy S in the US are all f***ed up. I Don't understant why samsung has to made such different model.
Then how do you explain that it's impossible to have 850 band working on any modem other than UGJL2, TLJL3, UGJK3, UGJK4 or UGKC1 without using this method. Be my guest and try to get 850 band on JPJ, JVK or any other european modem without using this methode in the first place. If you already did then it's not valid as the 850 band will stay. But I can confirm you that if you skip the part about BVJJPD or BVJJPG and then you try to turn on 850 band in the service mod with JVK you will never get reception on 850. I've tried it before I found this method on captivate forum.
So I might be wrong but I think it just a firmware limitation or compatibilities that blocks 850 bands when you have european or asian modem.
Flashing BVJJPD or BVJJPG does something special and after that you have 850 available regardless of the modem firmware you use.
If the limitation is realy hardware then samsung is complettly stupid but they seems to have learn their lesson as the SGS 2 is advertise as HSPA+ 850/900/1900/2100.
But I don't think we have any way of confirming any of these theory out of any doubt so I'll change my first post.
