hey guys,

i have as you have, the omnia i900 that working with GSM 850/900/1800/1900 but UMTS/WCDMA it's only on 2100

and some of you want it to be also UMTS/WCDMA 850/900/1900/2100 (full quad band!!)

now.. mabe we can make it.. how?

as i read over the net, the Band Chip is support this quad band and it's "mabe" only firmware open for this band..

i'm working on cellular company, and we have OMNIA-I900 for technical testing with "all bands open"!

you think if i'll download the Firmware from this phone.. and we will upload it to other omnia, it will open the bands??

how i can "download" firmware from this omnia? what i software i need to use for it? and how i can do it..

it's defently worth a try!!!

(this omnia full band phone not all day "in my hands".. so tell me what to do, and i'll try soon as i can every time..)

It wouold also be nice to see the version displayed on this handset - DX, XX, XA, etc. so we know the alphabet soup for the US.

The ROM dumping process will dump only the "PDA" part of the ROM.

Its very probable that Band lock will be in the "Phone" part of the ROM that can not be easely dumped.

One more possibltiy is that there are some settings in the admin panel.

I.e. see this post:

>>>>>

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.

>>>>

What settings do you have for: umts rf nv?

What settings do you see for WCDMA set channel? (it should list a range of Channels allowed)

This one might also be useful:

*#1546792*#

Password on admin setting:

*#81230*# (if required)

It only allowes to specify a specific channel in that predefined range 10562 - 10842, which is UMTS 2100 :)
