Has any been able to get 3G to work in the USA yet?
thank you,
jdm
I would say that it is imminent that the US version of the S730 will be released soon. AT&T or T-Mobile may pick it up (T-Mobile's 3G network in NYC just went live, but there are no phones). If so, I would suspect that some of these crafty folks (like Alcaline) would be able to extract the radio ROM, and make it available for the S730 that we all have (the european version).
But, here's the most important part... It all depends on whether or not the European version of the S730 has the radio chipsets that will support 3G on the frequencies that are 3G in the US. There is no known answer "available" to this, so it can only be discovered by testing.
The current S730 uses the 2100 band for 3G speeds and ATT is deploying 3g on 1900 and 850 I believe and they sell a decent ammount of 3g phones. T-Mobile is working on setting one up on the 1700/2100 band but I dont care for T-Mobile.
I have watched my phone at times flip into 3G mode for a few minutes then revert back to Edge, its trying but cant work properly without the right frequencies.
Check out the chipset datasheet. Bottom of page three explains the specific radio chipset combos and their support for different freqs.
I suppose, to save on manufacturing costs, they could have used the single chipset that supports 3G on all freqs (RTR 6285), but I believe this is unlikely due to the difference in model number that was submitted to the FCC (European version: WING220, US version: WING200).
Who knows though.
3G in US
Hermes models had different model #'s HERM100, HERM200 and had the same radios, in some cases minor difference such as case style, i.e removal of video calling camera etc. With any luck we have the RFR6500 + RTR6275 Combo, or as you mentioned the RTR6285 and just not a radio rom that allows 1900+850 3G. I was looking on the FCC site and they have some interesting screen shots, one of which shows one(s730) with what appears to be the front camera covered up and another which shows a radio rom(R 0.27.03.05B), one that, to do the tests would likely need to support 1900+850. Check Page 250 / 11 in the PDF. However, also in the test is the lack of any mention of 2100 Mhz test, which would suggest that either the US 3G Radio won't support 2100Mhz or that it indeed has different hardware that won't support 2100Mhz. At any rate it would be interesting to know if anyone has tried to flash one of the pre-prod roms for the wing 200 onto the wing220 and see if they are able to connect up to 1900+850 3G.

I suppose only time will tell.
Wow... nice investigative work. Very interesting. I'll start hunting around for the ROM.
[edit]
Searched google and, my favorite, napalm with no luck. I wonder if we can lure an FCC testing engineer into the XDA-dev realm. muahahaha
I was searching some of the other posts, and it appears that most of the pre-prod radio rom testing had been focused on GPS functionality. Has anyone been able to throw on any of the pre-prod radios with an ATT SIM and tested to see if it can connect to WCDMA -> US Band (1900+850) ??
I have no possibility to check the 3G in the USA from my location in Norway.
But just to get this clear, because I have changed my Radio more often then most people change their underweare.
Is everybody able to select WCDMA and then US Band in the settings?
I dont know if this is selectable on all devices or if this is made available after my radio flahings.
I believe all S730's have the following options available.
Network Type:
Auto
GSM
WCDMA
Band Type:
Auto
US Band
Euro Band
Japan Band
For it to actually be able to operate on all of these frequencies I believe it would need to use the the RTR6285 chipset as the other 2 combos would not support all of the different frequencies combinations.
US Band -> GSM 850+1900 / UMTS 850+1900 (ATT)
Euro Band -> GSM 900+1800 / UMTS 2100
Japan Band -> UMTS 2100+800 (not positive on this one)
If I change band to from Auto -> WCDMA I do not get an error but no 3G Icon and all calls fail. If I then go and change to US Band while having WCDMA selected it indicates that it cannot change to that GSM/UMTS Band. Also interesting, If I stay on WCDMA and select Euro Band, no error, but of course all calls fail. I then tried to change to Japan Band, no error and no phone calls. Finally I am still on WCDMA and I switch to US Band and I get the error that indicates I cannot change to that band. So, I would be interested to know Alcaline if you see the same behavior on some of the other radios you have been trying to see they allow the switch to WCDMA / US Band combo.
Thanks
Can anyone else confirm this behavior on any of the other Radios out there?

I have the ability to tell my phone I am in the states, but it does nothing (default settings though)
Was the US version (WING200) of this phone ever released? Or has anyone gotten the EU version to work on any US 3G networks? Wondering about T-Mobile...
Hello,
I need help with a Blu WinHD: I purchased one while in the US as a replacement for my broken phone, but once back in Europe I discovered I had no 3G connection.
A quick web search and I found my model variant (W510U) only supports 3G/HSDPA at 850/1900/1700 MHz, while my Italian provider offers 900/2100 MHz bands (Vodafone IT). However, another variant does exist (W510 L), and actually supports 850/1900/2100 MHz.
Since both phones feature the same SoC (Qualcomm MSM8212 - Snapdragon 200), will it be possible to change the 3G band used by my version? I was thinks about flashing the other variant firmware, or trying some dial string and see whether I can change Cell Network settings...
Any tips?

You need to be a VIP to download that. But still, I don't know which flashing tool should be used :/
Don't forget to reply if you find anything relevant!

I'm not sure. But the 3G bands always had been a hardware thing. So you can't change it changing firmware or something. It's not like unlock, it just doesn't have them.
@anthonws Wonderful, I'll try to decompile this firmware in order to discover whether there are some dial strings that could help. But of course, being able to flash it at once would have been better. I'll look for any other flashing options as well.
@m1k3_ I was thinking the same at first, but later on I couldn't explain myself how could that be possible with the very same SoC on both model variants: if the SoC embeds the radio controller, what else can pilot the 3G bands? I would have better to get the chance to read the detailed datasheet of the Snapdragon 200...
Unfortunately, I finally got a reply from BLU Support Service, stating that 3G bands are actually hard-coded, so no software change can actually modify them....
I'm very sorry about that, I got to like this phone very much....

I brought BLU HD W510U as well. But my question is : does your W510U have iuminous backlight for back key, home key, search key at night time?
Is there any development about the question ?
... buy a Lumia that supports LTE? My 1520.3 has support for a number of LTE bands, for example. I'm going to go way out on a limb and guess you don't know much about how radio, much less cellular telephony, actually works... Enabling bands is at least a radio firmware change and sometimes a hardware change. It's not something you can do in device software.
On Android devices there is possibility to unlock some bands
also Lumia 640 has all bands (LTE version) and i think there have to be some hack to unlock band if radio has it
On some regions is LTE disabled, but if you flash ROM from other region, you can use it. I tried Indian ROM on my L1520 and no LTE, with French ROM is LTE enabled.

that problem is software level but i am asking different one
on nexus 5 USA version one band (band 3) is locked and if you hack it with field test you get it and use in Europe
i need such hack for lumia
in addition lumia 640 has all LTE bands
and i might think on lumia 635 there have to be any band (band 3 or band 20 ) to get LTE in my Country
And what about different versions of 640/640xl? Some of them have LTE enabled, others don't - is it possible to enable it manually? Someone in forums posted that he could enable LTE on Lumia 525

I am interested to find that thing out ! and I don't know how to enable LTE..
I have tried to compare registry from lumia 640XL DS LTE vs 640XL DS 3g, found some keys on LTE version missing in 3g version but could not test because in my country there is no LTE(
Any news regarding the issue?

Is the QCN = radio rom? As i understand it, it's more of a partition backup.

I would say no, as this phone definitively has got an encrypted phone NV registry just like the OP2 which effectively makes it as good as impossible to tamper with the locked NV registers.
Try this , Flash any of the mm roms like oos 3.5.1 or 3.5.4 . get into the service menu by dialing *#*#4636#*#* . touch phone info and then the three dots on the top right , next touch select radio band , after that you will get a list which says US band , band 31 , band 32 etc. touch band 43 and wait for at least 2 minutes . I had inadvertently switched to US bands by touching the US band option and lost all 2g and 3g connectivity and got them back using the above method.

Not trying to get 2G or 3G back. Want to get LTE band 3
Dear all,
is there any news on this? I bought a 3T in China as I'm currently living here but will return to Germany sooner or later and would like to use the whole band available there. It seems some more channels are used in Germany.
Thanks and best regards,
Matthias
Please help to me.. (and to all Japanese)
I use S5 mini (G800F) in Japan now.
But this phone is can't use band 19....
Band 19 is so important band in Japan.
I heard this phone can't change band , because used Exynos (not Qualcomm)
Do you know how to change band to 19?..
not sure if this has any relevance whatsoever but i managed to get as far as..
*#*#4636#*#* (dial into phone)
Phone information > Menu (top-right) > Select radio band
I'm unable to connect to any of them (always returns 'unsuccessful') but I wouldn't know what it would say for you or if the menu even exists for you, I have a SM-G800Y model. All the best
