... In the AT&T and International versions of the Atrix... why can we not enable HSPA/UMTS on 900MHz through flashing radios or other software means?
Edit: Phone is an unlocked AT&T version on O2 UK with O2 sim.
Because the 900MHz band that the Atrix uses is part of the quad-band GSM, which is 2G/EDGE, not UMTS. Those are two different standards.

But the international supports UMTS/WCDMA/3G/3.5/HSDPA/HSPA/HSPA+ on 900mhz going by all of the spec sheets I read.
UTMS is 3G. HSDPA is 3.5. A standard of WCDMA. HSPA is another WCDMA standard which again is a 3G Technology (3.7G?)... Either way they all come off the same 3G cell

I don't know about the other bands but you specifically mentioned the 900MHz band so that was what I was talking about.
More than likely the carriers have locked the radios and/or hardware. It's like other carrier's world phones will not work on AT&T/T-mobile, even though they technically can support those bands.

There doesn't seem to be any logic to why other than software as the radios taken out of all firmwares work on both versions. The only logical answer is software (if I could SBF flash a UK firmware, not CWM that would help, but there was other differences with the mainboard right?), or its the same chip just slightly modified without that band included.
I was mooching around system folders trying to find anything that could give me a clue, but to no avail.
I think it has something to do with what module is used, which is a hardware component. I know the AT&T Atrix uses the Qualcomm MDM6200 but I have no idea what other versions use.
I might be wrong though.

Indeed, so logic would say that if we flash international radios for a different module (if they are different) would soft brick the phone or cause the phone to no get any kind of reception what so ever.
I do find the international radios and att radios (other than the stock and 1.87) make the H+ signal level not go over 1 bar.
I'm not sure about bricking the device but I know they usually have those radios locked down pretty good which is why most people need to buy unlock codes or get their carrier to unlock their phones for them. It's not very common that end users can crack them.

SIM Lock and Radio locks are two completely different things. SIM locks are easy to break with a £10 note and a guy with some device, a radio lock is more difficult we dunno if its hardware or software.
Has anyone got an international/uk/europe Atrix that they'd kindly tear to pieces to see if its the same cellular modem?

Pardon me for asking but this has bugged me for a while:
I doubt if the Raphael is really produced in two hardware versions: one that supports UMTS 900/2100 MHz in Europe and another that supports UMTS 1900/850 MHz in the US?
Do any of the European friends here flash the Radio ROM v1.14.25.35 (extracted from AT&T ROM in the US) to their European version of the Raphael and with a tweak in the registry key

i.e., to make the UMTS 900 MHz band known to the machine, are able to connect to their 900 MHz 3G network properly?
Apparently, the 900 MHz UMTS band was not included in the default BandType after the American AT&T Radio ROM is flashed.
This is actually a very good & important question & point. Particullarly with the newer devices that are comiing out. In an effort to streamline production, HTC has changed somewhat the way the restrict devices from operating on different bands. Now you find that even CDMA & GSM device are able or would be able to operate, strictly speaking of hardware, on one or the other network except for the firmware. According to FCC documents, HTC is locking devices to networks via the firmware. This may make it possible to opperate any device on any network give that there is a place to insert the sim card.
I am using the new radio, & I have been able to use it on both the US & EU gsm frequencies. You can selct the band you want, but you need to use the band switch program as the EU band has been disabled via the registry, but it still exists within the radio firmware.

Thanks, gsleon3 for your input. I have this doubt because many people on this boards mention cross-flashing and the issues with two different hardware versions; whereas, according to Section 1.1 on "Product Features" of the Raphael Service Manual, the hardware itself supports HSPA/UMTS on 5 bands, i.e., 850, 900, 1700, 1900 and 2100 MHz and GSM/GPRS/EDGE on 4 bands, i.e., 850, 900, 1800 and 1900 MHz. Raphaels are produced in different SKUs with some bands selectively enabled, though.
I'm in Germany w/ a German O2 XDA and I've flashed the new radios with no problems. I haven't flashed to .25.35 yet, but probably will tonight.
[EDIT] Just installed .25.35, and it works 100%. We'll see about battery life tomorrow... [/EDIT]

[Q] Do we know the extent of the AT&T-friendly UMTS hardware in the T-Mobile Vibrant?
So as a lot of you know, the T-Mobile U.S. version of the Samsung Vibrant turned out to have hardware support for AT&T's 3G. But from reading user comments, it sounds like the T-Mobile Vibrant only has UMTS 1900, and not UMTS 850 as well. Obviously this isn't a problem if you've only got 1900 in your area, but I'm pretty sure we do have UMTS on 850 in my city.
I'm wondering if anyone with the T-Mobile Vibrant has tried using the extra 3G band(s?) and can confirm which are present. Is it 1900 and 850, or just 1900? Further, does anyone know how can I check to see which frequency AT&T provides 3G on in my city (short of relying on the clueless CSRs at my local retail store)? I've got a buddy with a Nexus One on AT&T, is there a quick way for him to see what frequency the UMTS tower he's connected to is using?
In the interest of completeness, I'll cover the questions that I'm sure will get asked so that folks don't **** up the thread with them.
Why not just get an AT&T Captivate?
Handful of reasons. I prefer the Vibrant's aesthetic, but more importantly because AT&T doesn't have T-Mobile Vibrant IMEIs on file. This means you can add and drop data at your own discretion instead of being required to use it, and it also means that their system will treat it as a dumbphone. Definitely a perk.
Why not just get a Galaxy S Vibrant from Bell in Canada? It definitely has 850 and 1900.
This is what I'll end up doing if the T-Mobile one doesn't work out, but it's a pretty big pain in the ass to get Canadian phones shipped down here whereas the T-Mobile version is readily available. Also, no warranty!
Thanks guys.
From what Ive read, the Vibrant works on 850/1700/1900/2100. --See edits below--

It doesn't work on WCDMA 850. Doesn't support it. Try selecting it only and put a AT&T sim in and see if you get 3G. Yea you won't, then try selecting 1900 only and what happens? Yea exactly.
Well, I dont have one in front of me to experiment with my AT&T and T-Mobile SIMs, Im just going off the side of the box and whats listed in the menu (both say 850). I currently have a Captivate and a Fascinate, but Im looking into getting the Vibrant instead for a number of reasons so I was just poking around. Sorry if I was passing on bad info.
~T.J.
EDIT: I thought I read of some people getting it to work on 850, but that could be wrong. Im looking again... Could it be there just isn't 850 coverage where you tried it and instead was 1900 coverage? These are OLD maps though...

Because the T-Mobile 3G network in the U.S. is listening for 3G data in the 1700MHz and 2100MHz bands, it’s the only U.S. network with which the Nexus One phone can communicate. AT&T’s 3G network listens for phones transmitting 3G traffic in the 850 MHz and 1900 MHz bands, which the Nexus One cannot do. All it can do is send 2G traffic in those bands, so it does, making a slower data experience for those using the Nexus One in Ma Bell’s mobile network.

Just because the it's listed in software doesn't mean it can work. The Fascinate is a CDMA phone and your gonna tell me because you see the bands listed in software that it will work on a gsm network? Really? Either way I'm not trying to get you down. Just saying if that were possible, it would have been mention already. To conclude though, it all comes down to hardware support, the software is just mirrored on all galaxy s phones. The Vibrant only does 1700/1900/2100 for 3G. The 850 band would have benefit you better for in building support, but it's not supported.

Heres the rest results for the Specific Absorption Rate (showing 850 Mhz GSM around page 25):
http://www.nwallwheeldrive.com/misc/SAR Compliance.pdf
My conclusion? Id say its capable because it has all the hardware (since they were able to test it), but depends on the network around you. That, or they literally software blocked it for some reason.

850 gsm != 850 umts
D'oh! Talk about needing to sleep! As I said I'm just here to learn too as I want to pick up a vibrant, but apparently I need to sleep before thinking and posting. Sorry about that!

Thanks for all the responses, guys, I really appreciate the thorough feedback.
Sounds like 850 is a bust, which is really disheartening. There's loads of T-Mobile Vibrants on eBay in the $340-380 ballpark, but it's going to cost closer to $500 to get a Bell Vibrant down here.
yeah the phone supports 850GSM but not 850WCDMA/UMTS/3G

Can't do much about it since AT&T version doesn't support the 3g/4g band for T-mobile.
At&t gs2 doesn't support t-mobile frequency for 3 g.

The AWS (1700) bands are supported only by a handful of carriers. It doesn't exist at all in Europe and Asia. There's little reason for manufacturers to include it on their global phones as so few people use it. It's the reason the T-Mobile SGS2 has a Qualcomm chip instead of Exynos like the rest of them. After the merger, it won't even exist in the U.S. any longer as AT&T plans on using it (1700) for LTE. If you want versatility and the ability to use unlocked phones, change to AT&T.

In order to get T-mo 3G, a phone must support HSPA on 1700MHz AWS band, not 850MHz. As such, only phones from T-Mo or some Candadian carrier support 1700 band. Rest of the world use 900/2100 for 3G and AT&T uses 850/1900 for 3G/4G.
You are never going to get 3G on T-Mo on any phones from AT&T. Period. Give it up.

TMobile uses 1700 up, 2100 down. If the handset doesn't support 1700, you are out of luck.
Correct. Many phones support the 2100 MHz International band.
T-Mobile's network is weird though, and uses both 1700 and 2100 MHz at the same time.
My guess is that UMTS1700 support and not 42 Mbps HSPA+ is why the T-Mobile variant of the GS2 is such an oddball phone.
NO AT&T phone and only a small handful of international phones support T-Mobile's 1700 MHz band.
Similarly, only one or two T-Mobile phones (The Vibrant being one of them) support any of AT&T's 3G bands, but none support all of AT&T's 3G bands to my knowledge.
The interesting thing about this entire thing is that if you go into the modem band selection it lists 5 different wcdma bands including the aws 1700. I enabled those bands and tried using a tmo sim but alas it still only worked on edge. It may have just been there cosmetically rather then actually supporting aws bands. use dialer code *#2263# to access the band selection menu. Maybe there is a way to get it to work.

Typically, the s/w supports multiple versions of h/w. Just because an option's in the menu doesn't mean the h/w's available to support it. The same thing happened with the T-Mobile G2X. It was supposed to be quad-band, the option was in the ROM, but the radio wasn't there to support all the bands.
Hi guys,
I am using 77.30P radio in Brazil and having problems with the signal, the carriers here are a mess, the same carrier uses from 850mhz to 2100mhz...
My question is, what basebandd (radio) can i flash which uses all those frequencies?
If someone can help me out by pointing the know frequencies for the most common radios available it would be of great help!
Thanks in advance
All AT&T radios can use UMTS (3G) 850 and 2100 if I recall correctly.

Google what bands does AT&T use for 3G. But as I said, I think it's 850 and 2100.
AT&T uses the 850 and 1900 bands for 3G. As for the radio version, use the one that came with your phone. The atrix supports W-CDMA 850/1900/2100 for the AT&T version but mine in addition to those listed above, supports the 900 band as printed on the box.
If there's any different radios for MoPho?
I wanna get UMTS 900 working on Photon. I know that it's not listed in the specs, but so as for Atrix 4G, and guy here flashed another radio and got UMTS working.
So, if there's any info about MoPho?
Where i can get stock radio, so i can try another one?
If Atrix 4G's radio will work for Photon? (I suggest hardware is pretty the same).
Any input on this is appreciated.

So, if there's any info about MoPho?
Where i can get stock radio, so i can try another one?
If Atrix 4G's radio will work for Photon? (I suggest hardware is pretty the same).
Any input on this is appreciated.

from what im seeing here
-----The phone operates at frequencies of CDMA 800 / 1900 / GSM 850 / 900 / 1800 / 1900 / CDMA2000 1xEV-DO Mhz. -----
i would think it would work does it not work for you? , the photon community is still working hard on getting everything unlocked fully and right now what seems to be the main focus for the dev community is getting roms and wimax to work on an unlocked bootloader,
OK. first of all i'm personally not interested in CDMA part.
It operates
GSM 850 / 900 / 1800 / 1900
UMTS(WCDMA as i understand) 850 / 1900 / 2100
Local operator uses UMTS 900. So EDGE only for me. And i got H+ icon with another operator.
But i suggest the only difference is the radio flashed in the phone.
One user on XDA reported that he get UMTS 900 working on hit Atrix 4G. (Atrix got the same freqs listed as Photon, without UMTS 900).

so far as i know they havent gotten a full unlock of the frequencies they use and since the photon is really sprint only here in the states, it makes it hard to jump from one band to another since no one really has it, i know that in japan they had a wimax photon, that one might be a shot i just have no clue where to find a sbf file for it nor whether or not it would even flash to the sprint photon, are you out of the US and if so which provider?
There's a topic with leaked sbf that says wimax working. not sure if it's from japan.
I cannot find any radio in .zip or .sbf file. If i could find one, even stock radio, I could try flashing one from Atrix. Dunno if it help or not, but why not to try?
Yep, I'm out of US, in Kazachstan.
Beeline and Tele2. Second one require UMTS 900.

talk with joker or shabby they should know where its at, im not that far into developing as they are, im just trying to learn as i go
This is definitely something i would like to see happen in the future. Im moving to Sydney at the end of this month and plan to take trips frequently to area that only have dual band coverage on Optus (UMTS900/2100). So until someone hacks this i will only have 3G in Sydney where they have HSDPA2100Mhz.
