AT&T SX56 and Special Rom Edition Rom 1.2 troubles

I had an AT&T SX56 phone and it worked great. I just bought another one because mine broke. I used the sim card that was in my old phone but it doesn't pick up ANY network. When I went to manually choose a network, they were all European networks. Nothing from the US was even listed. It has a somewhat different software that I am used too. When it boots up it says it is running xda-developers Special Edition ROM V1.2. Is there anything I can do to fix this all up Also, the desktop is a bit cluttered for me, is it possible to have just the standard AT&T desktop?

i think it has something todo with different bands (900 1800 1900). but don't know the exact details.
maybe try a search on band selection?

It helps alot .

Have you tried entering bootloader mode and choosing 900/1900 from the gsm menu?

after reading this post I am wondering if you can somehow change the band that a Qtec 2020 runs on. right now mine runs on 900 usa but I'm wanting to change it to 850 usa cingular uses it and it has a much stronger signal in my area. Please let me know if there is. thanks

Omnia i900 with no 3g?

I just bought a singapore-configured omnia and i can only get it to connect to edge here despite being in a known 3g network... In the connection manager i only have options for "cellular line" and "cellular line (gprs)" (as well as haynes and bluetooth etc), but no "cellular line (gprs, 3g)" as I do on my other phone...
Any suggestions as to how i might get it to recognize the 3g in my area? (rogers/at&t).
Thanks!

if i'm not mistaken i900 has 3G but only in the 2100 band, maybe you can check with your operator what 3G band they are using...

I believe rogers runs their 3g on 1900 and there is no option for 2100 on the phone, only 850/1900 and 900/1800...

what you are saying is the GSM band, what I meant was the UMTS band which is 2100 for the i780

I have no option for UMTS in the phone ;\ I believe rogers runs on 2100 also but i'd have to check my other phone... is there somewhere where 3g/umts could be disabled on the phone? The specs say that it supports tri-band and umts.
edit: just checked the rogers phone, under settings -> phone i have a seperate tab for "band" wherein i can choose the gms/umts band "gsm(900+1800)+umts(2100)" etc but on the omnia there is nothing of the sort.
is it possible that the korean version of the phone somehow has umts disabled?

try under the MORE tab in phone settings, frequency in BAND SELECTION should be set to automatic.

This is a big mystery to which there is no real answer.
I have a I900 as well, but I do not have 3G/WCDMA in the US via AT&T which uses 850/1900 bands (which I believe is what Rogers and Fido use).
Here are some interesting bits:
- The I907 is a North American version that supports 3G on 850 and 1900.
- No one to my knowledge has seen any different hardware parts related to the Cell in the I907 vs the I900. The radio in both supports 8 of the UMTS bands that have been proposed (only 4 are in common use, and one of those is only in Japan). The cell antenae of the I900 are designed for optimal gain in the 850/1900 bands.
The Radio is idential to that of the Diamond, Touch Pro, G1, Kaiser, Touch, Touch HD and anything else using the 7201A or 7200 chipset. The I900 and I907 do not use this chipset, but it uses the same radio hardware.
No one was able to get the EU Diamond to use the 850/1900 GSM band, and in fact the US Diamond has the same radio Firmware as the EU diamond.
I was confident that if anyone could figure out how to make this work, it would be people at XDA on an HTC device (caveat - there are a lot of europeans here who don't care about 3G in north America, so I may have been wrong there)
Where does it say tri band UMTS on your phone?

I just upped the UK t-mobile rom into the phone and surprise, the profiles for singapore internet are still in the phone... HOW is this possible on a full rom (pda + phone) flash???
anyways, looks like the umts spectrums we use are locked in the firmware for the phone, despite the radio being able to use it ;\

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.

There are many Roms Available on Modaco
www.
It seems like there are at least four places in which firmware lives:
- "Phone" (usually called Radio)
- "PDA" (the rest of the ROM)
- "CSC" (seems to be for branding. I.e. TMobile has a special .csc file as compared to stock ROMS with similar firmware)
- GSM settings, accessible through dialing obscure number on the Phone. Search Modaco for a list, people seem to find new ones every day. Some of these numbers just effect the ROM settings, but some seems a little more powerful.
- In some of the recent Roms there is a Band Tab in the phone settings, but it only lists "Auto", "850/1900", "900/1800" and "WCDMA". WCDMA is 2100 in the rom I have installed (Signapore PDA with an "Open Market" Phone (XXHI2) )

mine, with the t-mobile rom, only shows 800/1900 as an option in band selection ;\

US 3G Diamond - What gives it 3G

I noticed an unlocked US 3G Diamond at Best Buy today. I'm sure this has been asked before, but I can't seem to find the answer.
What makes the US version work on AT&T with 3G over the imported version? I have not seen a radio upgrade that allows it yet. The handsets actually looked quite similar with the exception of the back and battery.
I'm just curious whether to pick up the new one in order to get 3G service, or is there a radio update expected?
Thanks to anyone that can shed some light on it for me.

I have a US 3G version and the freq. that at&t uses here has been enabled.

Sure, it would be the 850 and 1900 Bands. But there are Quad-Band radios available for the EU Diamond. I wonder if it's a question about the device not having specific hardware or just being able to enable those bands to work properly.

Sorry for my english
he American Diamond has quad band in GSM and only two band in HSDPA, The people here says that is a har problem not the radio, the people put the american radio (08) in European version and dont work.
The American version came with the 1340 mh battery and without the front camera. Carlos

I have a Touch Diamond I bought last week from new Egg, just like the ones from best buy. For some reason, I can pick up the 3G signal and it will hold on to it for just a second, then x..{disconnects}..then immediatly picks up Edge and then Hsdpa?
I get 25% Edge and 75% Hdspa. I guess if you read the box, it says it picks up a 3.5G internet Broadband Connection....Anything over 3.5mbps is Hsdpa.

I notcied that the US version had the 1350 mAh battery instead of the 900 mAh like the EU version. Was there any documentation on why they did this? Has anyone checked if putting the smaller battery and slimmer back on the US version causes any problems?
I also find it odd that HTC briefly listed the Diamond as a Quad-Band phone on their website, and have since changed it back to a Tri-Band phone.

I still have hope that our European Diamond will work with US 3G with somefirm ware flash or something

No, it will not.

Rhod100 x 2100 3g

After searching this and other forums for like the whole day I am able now to understando some things:
1 - My carrier here uses 850 for 3G
2 - The RHOD100 is the european GSM model and uses 2100 3G band
3 - I know how to do the HardSPL flash
4 - I know how to do the radio flash
5 - I know how to do the ROM flash
What I just can't find is (NOOB DETECTED!!!)
Can I flash a radio rom that will connect to a 2100 3G network to my RHOD100 model phone? I tend to believe the answer is no due to hardware restrictions but I decided to ask since you guys know better

im afraid that the band is hard set in the hardware, although POSSIBLE to change it would require taking apart the phone and swapping components.

I just come from another thread with the same story and all I can say is welcome to the club!! I myself bought the T-mo version and my country uses 850 long story short.. My pocket holds a Tilt 2.

Noob Rhodium Device ID confirmation

Hi guys, first post here! I've been reading a lot about ROM Flashing, checking all cool ROMs and how to HARD-SPL which is awesome... problem is I'm not 100% sure which device I have! And correct identification is critical for any flashing or H-SPLing...and I've already UTFS... I believe the Touch Pro 2 can be identified as an hybrid band phone, whit GSM and CDMA bands and I can choose between GSM and WCDMA... I'm running apparently a carrier free, unlocked version so when cookers state "for Sprint, T-Mobile...or GSM ONLY blabla" I can't really tell...
Device info:
Battery out, label states: RHOD100
WM 6.5 Pro
CE OS 5.2.21854 (Build 21854.5.0.80)
Device info:
ROM V. 1.87.421.0 (67729 WWE)
ROM DATE: 10/01/09
RADIO VERSION: 4.49.25.17
PROTOCOL: 61.44tc.25.32U
So please help me which tutorial should I follow? CDMA ones or GSM? Since I'm in Peru and using Claro as mi carrier (GSM) is my phone a GSM one exclusively? Will I ever be able to use the 3G? (here in the 850MHz band, HSDPA) Currently it seems this phone can do EDGE only but I see the option in the band settings menu. I don't want to brick this brand new phone in my hands! Please help me to be sure! (oh sorry my english, it's not my native language)

RHOD100 means that you have a GSM device.

That's it? So I should follow GSM H-SPL... and GSM ROMs...?
It looks exactly like the Deepshining's ROM thread pics, keyboard and color scheme.
Thanks!

Yes it is You may easily install Deepshining GSM ROM if you wish.
Just don't forget to use a GSM HSPL first.

For the next time: A CDMA device doesn't have slot for a SIM-card.

Thank you Jackos, you have been very helpful!
Just a thought, why my TP2 just shows "E" (an EDGE connection) if 3G is available? My carrier provides 3G via HSDPA via 850MHz band so... maybe I'm missing the 850Mhz band? Though I can see is as part of the options in the setting menu? Will a RADIO rom flash fix this?

Which carrier do you have? The 100 is the world phone, and the high speed radios work on European networks, I believe. The US versions are the 210 (T-Mobile) and the 300 (AT&T, I think). There are other model numbers for CDMA versions.
If you are using the European model I don't think you can get 3G here in the US. Wrong hardware.

CDMA world phones do. My CDMA TP2 has a SIM slot.

Didn't know that, thanks. I'll keep in mind.

I'm in Lima, Peru and "Claro" my carrier uses the 850mhz band for 3.5G (HDSPA) here. I believe I have UMTS available in the settings menu in the 850 but since theres a HDSPA optionI thought that would allow me to connect. It looks the HDSPA option is not available for the 850 band but theres nowhere this is documented. Since I will flash a new ROM and most probably the newest RADIO version available, I will post any changes. Looks there's not a lot of info about the RHOD100.
OT: Radio roms are bands specific? (US EU versions?)
