I900 3G in the US

Recommended Posts

Based on this post:

>>>

What I can tell from the FCC files for the i-900 Internal Photos at https://fjallfoss.fcc.gov/oetcf/eas/reports/ViewExhibitReport.cfm?mode=Exhibits&RequestTimeout =500&calledFromFrame=N&application_id=476604&fcc_i d='A3LSGHI900://https://fjallfoss.fcc.gov/oetcf/eas...'A3LSGHI900://https://fjallfoss.fcc.gov/oetcf/eas...s...'A3LSGHI900 is that Samsung is using a Qualcomm RTR6285 for it radio which according to Qualcomm:

"Support for Eight UMTS Bands, Four EGPRS Bands, Triple-Band Receive Diversity and GPS Integrated into Power-Optimized RTR6285 Device" Qualcomm News and Events - Qualcomm Announces World’s First Single-Chip, RF CMOS UMTS Transceiver with Integrated Receive Diversity and GPS.

So I think that it will be a matter of firmware update to have it working on any UMTS.

I hope this helps, based on this I went ahead a bought my Omnia! Can't wait to have it!! smile.gif

>>>

It is very likely that the I907 will just be an I900 without a front mounted camera and with different firmware installed.

Hopefully someone smarter than me will find/cook/combine the firmware necessary to put enable 3G on the I900

pidsw -

I'm with you on this. I'm in the U.S. and with AT&T.

From what I'm hearing, the Samsung Omnia will now slated to be released as the Samsung Mirage here in the states. This is "supposedly" able to tap into U.S. 3G.

Im hoping there is a wizard out there who can figure out how to enable/tap into AT&T U.S. 3G networks for the Omnia i900. EDGE is pretty good, but need the speed for the Sling Mobile Player. ;)

Based on the internal diagrams of the I900 there are at least three Antennas:

One for Bluetooth.

One centered on the 850 Mhz frequency

One centered on the 1900 Mhz frequency.

Given that this is exactly what AT&T uses for HSDPA and this is what the Diamond and many other world phones have, I find odd that the I907 would have anything different. (Although I have not seen the internal photographs)

If the design was only for Europe and asia I would think that they would use aerials centered on the 900Mhz and 1800Mhz frequencies, or possibly the 2100Mhz frequency.

From what I have seen, Handset manufacturers only design different internals for different areas if they absolutely have to.

Building chipset designs is expensive. As are the fab plants to create the designs.

Its entirely possible that all Omnias are actually dual-band UMTS, and not supporting all bands now simply because they are not licensed too.

Then it could be possible that Samsung will just unlock the american band when Omnia will pass FCC certification in US.

It was similar story with HTC Diamond (though here it was with GSM band being ROM-unlocked).

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#

(All the sub-menus are also accessible directly using similar codes. I've posted rapidshare link to a couple of files that contain those codes, as well as very useful

registry tweaks, at the end of this post. Please mirror it, as I used free rapidshare account, good for only 10 downloads)

Anyway, 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.

Here is the link for the stuff i mentioned:

http://rapidshare.com/files/159576760/reg.....menus.rar.html

By the way, I would have started a new thread for this issue as it fully deserves it, but unfortunately it looks like I don't have forum privileges to do it.

Is anyone out there able to help apo11on?

I really would love 3G in North-America. B)

Trust me on this. It is just a matter of time when a US ROM for 3G data network will be ported or cooked by several excellent contributors on this forum. Why? because coming from a RF and system background, if the HW is ready which I strongly believe Qualcomm chipset can do (just the analog front end and its common Rx architecture), the register bit settings in the FW can be tweaked properly to either support all 3G bands or any of them. It is a wide-band Rx chipset and the FW is there already, just enabling this and disabling that with some optimisation and there we go.

Is there anyone with a Diamond that cares to help appo11on?

Please don't let this thread die...

Don't call me that. And no - no HTC Diamond users give a damn. It would take less than 2 minutes to look up those settings I requested on their device, but even though this info request has been posted on several forums no Diamond users replied.

Personally I'm not gonna wait for 3G forever, new cool phones come out all the time, and if something like this:

http://www.akihabaranews.com/en/news-16961...ean+Market.html

hits Verizon any time soon - I'm gonna switch to CDMA and sell my Omnia. Without fast internet access half of the features of the device are useless...

I agree - won't wait forever. Unfortunately can't switch to CDMA as I have a data plan 3 year contract with fido here in canada...

Sorry, but how is one supposed to refer to you? If not by your user name?

if you can afford to buy phones like omnia you can definitly afford to pay get out of contract penalty, it wont be nearly as much. I have AT&T contract too and I have no problem breaking it if I have to.

Oh, and you didn't call me by my user name - you misspelled it and that's why I said what I said.

I really dont want to switch out of AT&T though... I like the roll overs lol and most people i know have it so it works out better for me.... Im still trying to find those settings for you i haven't forgotten.

I would guess that the fastest path to 3G on the I900 is one of:

Rip apart an I907 ROM, combine it with an I900 ROM. The hardware is almost the same internally and the Kitchen is almost compatible. The ROM formats are identical. This is an AT&T Phone and there is a kitchen for it.

Find an I900L ROM. These devices are on currently on the Venezualia Samsung site but I have yet to see a ROM for them. I don't know that they are on sale yet or when they will be.

However, they look identical to the I900 but they have 3G on 1900 and 850 as AT&T does.

I think that Secany has seen one but he has not gotten his hands on on.

pidsw as usual, you provide very useful info - cheers mate! after reading your post about i900L i had my doubts about UMTS frequencies it supports, because of the articles like this: http://www.ADVERT LINK REMOVED.com/htmls/FCC-approv...cle-a_3275.html

and the fact that Venezuela uses a mix of euro/americas UMTS frequencies: http://en.wikipedia.org/wiki/GSM_frequency_bands

However, i was finally able to find a link for official FCC approval docs for i900L: http://gullfoss2.fcc.gov/oetcf/eas/reports...7A3LSGHI900L%27

and you're right - this model indeed does support UMTS 850/1900Mhz bands

So, I got only 2 things to say:

1) I think we're getting close. After we get our hands on i900L ROM it should be a matter of dumping the radio firmware image and flashing it back to i900

2) If secany had access to i900L and did not get that ROM - I want his liver!

on this Samsung Venezuela support page: http://ve.samsungmobile.com/mobile/SGH-I900L/spec

if you click "Mostrar todo", which means "Expend All" - it shows 2100Mhz only for 3G...Go figure what the hell is going on with

that model. I know FCC docs can't be wrong, so it's gotta be mistake on that webpage. Would be nice if someone from Venezuela with i900L replied.

I have posted on 2 htc diamond forums asking for them to look in there phone for the settings and i cant believe that not one person can take 2 mins out of there life to give me these settings...
