[Q] Enable band 900 - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hi !
First of all thanks to all members for all these great informations !
So, my question is simple :
Can we enable the WCDMA 900 band ( 8 ) as the AWS one ??
Some other versions like the Verizon can, but does the I337 has the same properties to enable it ?
In the ServiceMode, as the AWS band, the 900 one is here that's why I think yes but how.....??
Thanks

Any news in that matter? I am also interested in how to switch it on. Lack of 900 grinds my gears from time to time. I also seen it in ServiceMenu but I still wait for someone more into the business to make things clear

Enable GSM band selection

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 thinking if we could get 850mzh working if we know the correct ItemValue for it
REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\OEM\PhonePH]
"ShowBandPage"=dword:00000001
"ItemCount"=dword:00000005
"ItemName1"="Automatic"
"ItemValue1"=dword:00000007
"ItemName2"="GSM 900"
"ItemValue2"=dword:00000001
"ItemName3"="GSM 1800"
"ItemValue3"=dword:00000002
"ItemName4"="GSM 900 / 1800"

Taking a wild stab in the dark, given that 1, 2, 3, 4, 5 and 7 are taken, have you tried 6?

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.

It has been tried numerous times on numerous devices. Plus I have read reports from people who work for carriers who confirm this. Not to mention hearing from numerous people over the years who work in the industry who have a much better understanding of the situation.

How is it possible to verify the GSM Band Section?
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

1800 mhz GSM Band Missing

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.
-Daniel
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)
Even after running the program in the second post.

Hrb, what kind of Magician do you have?
I'm talking about a T-Mobile MDA Compact with a standard Rom WWE 1.10
And as told: I do have the Band Tab, but I can only select:
GSM 900 (Europe)
GSM 1900 (North America)
And Cong and Castiwo, have you ran the program and softreset the Magician?
I don't know how to run the program, that is the problem

Samsung Omnia i900 - unlocking UMTS frequencies

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....
..
Someone else has further evidence:
http://www.modaco.com/content/i900-...6374/open-omnia-umts-wcdma-850-900-1900-2100/
OK guys,
i had this omnia in my hands..
the Version says
PDA: i900LJJHK1/JJHK1
PHONE: i900LJJHK1
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..)

juvaknin, you posted this on Modaco as "PHONE: i900JJHK1" without the L. Please let us know which one it was. Thanks!

yes, it was suppose to be with "L" mabe i forgot it on Modaco forum
anyway i hope this is only Rom issue... but anyway i can't "Rip" the rom right now.. because this phone is 24/7 testing time and i can't "make it gone" from the test station to drop the rom to my PC
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?
Hi juvaknin I was reading on web that this i900L is for latinamerica and its frequency was
Cellularhone
Cellular_Networks: GSM850, GSM900, GSM1800, GSM1900, UMTS850, UMTS1900
Cellular-Data;Links: CSD, GPRS, EDGE, UMTS, HSDPA
found this at hxxp://www.pdadb.net/index.php?m=specs&id=1446

[Q] Does the European Optimus 7 supports WCDMA 850?

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.

[Q] Change from UMTS 900 --> 850

HI Guys,
did a bit of a search, but couldn't come up with too much. I;'m in australia, and have a mate who imported a UMTS 900 DVP. He now wants to change operators to Telstra.
Their "Next G" network is 850. Is there any way to hack it, or even flash with an 850 UMTS version of the ROM?
Cheers
Mike
Nope.
