Can the bandswitch.exe app be used to enable this radio interface?
thanks,
[email protected]
I believe that xda2 is triband so can do 900/1800/1900.
If it can do 1900, is this accessible using the bandswitch.exe ?
Also is it the same 1900 used in the states (usa) ?
[So if someone was travelling EU to USA, one could call up this
opened up tab section on the pda and then select something
compatible with either system....EU=gsm and USA=cdma. ??
XDA II is tri-band GSM, w/c you can use anywhere in the world who has GSM coverage. CDMA is a different kind of network. I believed that is US/North America the provider using it are Sprint and Verizon, if I am not mistaken. GSM network are used by T-mobile, Cingular and now AT&T is converting also from TDMA to GSM.
And the answer is NO, you cannot use XDA II to a CDMA network. You have to change hardware parts of it. BUT yes you can used it to 1900 network in the US w/c is GSM.

Hope this help!

Right. Within a few years however there will be phones where the entire radio transceiver is handled in software, and where changing system is indeed just a software upgrade.
(And then with some extra software your phone could also be a police scanner, family radio, marine radio, GPS receiver, Iridium/Thuraya/Inmarsat phone, GSM jammer/base station/IMSI-catcher, spread spectrum low-probability-of-detection military radio or celldar unit. Fun!)

Hello everybody,
I have a GSM oriented problem with my XDA II. Its not accepting 1800 GSM SIM card, when ever i try the 1800 SIM card service provider, it shows searching (but i can manually list the available network and set the network of the service provider. But it will not set the network and again goes for searching the network).
I initially thought its a Radio stack problem , upgraded the radio stack etc., but no result.
If i try a 900 GSM SIM card, it works well.
Can anybody help me on this area? What could be the problem. I tried the same 1800 GSM SIM card with other mobile phones like Nokia 7650, Sony Ericsson p800, Nokia Communicator 9210i, it works well on all these phone models.
My XDA II ROM information
ROM Version : 1.72.00WWE
ROM Date : 03/15/04
Radio Version : 1.14.00
Protoclol Version :1337.24
Please let me know what could be the problem...awaiting for your valuable inputs (FYI: I tried to Hard Reset the gadget atleast 5-6 times. I was using the same GSM 1800 SIM on this XDAII for last 4 months)
With regards
Thilak
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
change the xx for tt. Also wher did you buy this phone this info is real ?

Hello,
I have been reading about HTC Vision Radio around posts here (For both the G2 and the D-Z).
I saw that that the hardware specs for the Radio bands are different between the 2 models and that people can actually flash the Radios from both models into the G2 device (Which I own).
Considering I use an Israeli operator that has 3G network only (known that its bands are 850/2100 here), My question is - Does updating the Radio for my device is actually controlling the bands I can use with it ???
In other words, The main Radio circuit supports all bands and then the Radio Firmware locks it to use the specific band for the specific operator ? (i.e. T-Mobile) ...
I would love to know if that's true, so I definitely need to upgrade/update to a working Radio for my operator since I know right now I'm using only the 2100 Band and I'm getting real reception issues.....
Thanks in advanced,
Amir.
You're asking whether changing radios can change the bands used by the device for calling/data? If so than no it can't, flashing a different radio can't change a Tmo G2 to use at&t 3g bands etc... That's pure hardware.

hi
i have here few PCS of S5630L
its same phone but bands are not the same.
HSDPA 7.2 850/1900MHz
anyone think it can be changed via software ? or its a hardware issue ?
if so can i change bands filters ?
thx
anything ? anyone ?
it can never be done,
it is the internal radio which transmits and receives frequencies,
which is a hardware thing,
if i got you correctly S530L is CDMA and you want a GSM band

This model is not cdma, irs gsm model fits to some countries like brazil and argentina.
so this phone works only on quad gsm 2g network with no, but on 3g networks it works only on 850/1900 and i need 2100
On older nokia phones we changed anttena duplexer and bands filters and it did the job.
On newer phone like i9000 we can change bands via programing menu.
I just wonder if it can be done even with hardware changes.
Thanks
Anyone ??
