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...

TD Japanese Version couldn't use the WCDMA(2100) Network in China.
This TD seemed to use WCDMA 1700 in Japan, but couldn't be used in China. I've tried flashing a few Roms, also some Radios. Still it didn't.
Is this TD only support 1700MHz in Japan, which means it couldn't be used in WCDMA Network in China, which is 2100MHz?
Sorry for my poor translation.

The translation is better then the kanji. {I can't remember Katakana or Hirogana, been too long since I have read, wrote, or even spoke} If you can translate this back for Shishi, that would be wonderful. Thanx for the help as a translater.
Check the model # {label under battery}, & enter the model into the search engine @ PDADB.net. This will list all the frequencies your specific model is capable of. Model # will be DIAM*** {replace the *s with the #s on your Diam.}
You can flash ROMs until the chip burns out, but this will not help, because all the frequency data is in the Radio. If the site says that your model is capable of 2100 {which I believe it should be}, then just find a radio that runs at 2100MHz, & flash it.
If this is a CDMA model then I am not too sure what the frequencies are. GSM Touch Diamonds are quad-band phones & definately utilize the 2100MHz WCDMA. Soe GSM Diams only show the tri-band frequencies, but if you just flash a quand-band Radio to it, & it'll be fully functional as a quad. It has the Hardware, you just may need to change the software.
Also, if you go to the phone settings, there is a tab for "Band". Look there & see if the 2100MHz is listed. If it is, check that it's enabled. If it's not then just flash a quad radio.
Good luck

Thank you for your help!
检查你的TD的型号（取下电池你就能看到），将你的手机型号输入PDADB.net的搜索引擎，它将会列出你的型号所适合的频率。型号是DIAM***。
你可以刷ROM，但是这没有作用，因为所有和你频率相关信息都在Radio里面。如果你的型号适合2100Mhz，那就选择一个2100频率的Radio，再刷Radio。
如果这个TD是CDMA型号的，那么我也不清楚他能适合频段是多少Mhz。GSM的TD是4频手机，所以口肯定能使用WCDMA的2100Mhz。GSM只显示3频，但如果你刷了四频的Radio，它就是个全功能的4频手机了。你只需选用合适的软件来激活它的硬件。
此外，如果你进入手机的设置项，其中有一个频段(BAND)选项，看看是否其中有2100Mhz 的频段，如果有，只需启用即可，如果没有，则需要刷一个4频段的Radio

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!
anthonws
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?
TLDR:
Bought a new phone in NZ but I live in US, it lacks all 3g and LTE bands for T-Mobile
Tried flashing stock firmware to overwrite with US variant radio; didn't work, still Asia Pacific (APAC) radio
Is is possible to "change the variant" from XT1805 to XT1806 to get US radio? Or otherwise install US radio version?
If not, does anyone have experience unlocking additional bands with QPST/QXDM on this model?
Finally, can anyone confirm if any custom ROMs contain a radio/modem worth trying?
The details:
While traveling my Nexus 5x bootlooped, so I bought a Moto G5S Plus (XT1805, dual-SIM, 3/32 edition, software repo is retapac) in New Zealand, naively thinking that it would work in the US since it's also sold in the US. Got back from my trip and the phone cannot connect to anything better than 2g (EDGE) (but oddly on layover in San Francisco LTE worked). I'm a T-Mobile customer and found that this phone lacks the key T-Mobile bands UMTS1700/2100 (band 4) for 3g and LTE1900 (Band 2) LTE1700/2100 (Band 4) LTE700 (Band 12) LTE1700/2100 (Band 66) for LTE. Now I'm pretty sure the hardware support is there, I just need to switch the radio to the US variant (XT1806). Of course I can't return the phone now, and Motorola reps were worthless (level one rep insisted no US phones work overseas at all!)
What I've tried:
I unlocked the bootloader and reflashed the latest (SANDERS_NPS26.116-61_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip) stock firmware from the firmware center. Upon rebooting, even though the firmware notes indicated a US version, it must somehow see that the phone is XT1805 and flashing the modem and baseband still resulted in APAC radio bands and no LTE signal. I tried also flashing the SANDERS_NPSS26.116-45-5_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC version, which worked except the gpt.bin file didn't install since it's an older version of what was already on the phone (validation failed due to not allowing a downgrade). After reboot and setup, I'm still on retapac with no LTE service. None of the firmware versions indicate a specific region, and this long thread leads me to believe the firmware is for all variants, so somehow it recognizes the variant on install.
Other Options
I know it's possible to also root with TWRP and Magisk and then install a custom kernel/ROM and use some special tools (QPST and QXDM) to modify the NVram to unlock additional radio frequency bands via this thread. I'm willing to try this, but I know it's risky and not fully documented for Moto phones (guide is for Sony). In the end, I don't really care about keeping the APAC bands - I'd be happy to just switch the radio bands to the US version.
I've read over 100 web pages and forum threads in the last few days researching this and looking for solutions. I'd much rather find a way to install the US version of the radio/modem and baseband, but if that's impossible, I'd be happy for anyone to share experience with unlocking bands on this phone. Finally, if these are not good options, can anybody confirm a custom ROM for this phone that includes a radio/modem so it doesn't use the existing stock radio/modem?
Thanks and sorry for the long post, just wanted to provide as much information as possible. Thanks!

Did ya try this
Dial *#*#4636#*#* to get to field service menu
Hit menu - upper right - then select band, I think, you'll see it - first option
Select usa - I think that was it - you'll see what I mean
But, I can't remember of hand what bands are supported by this device. Google will remember though, ask him!
Here's a link to specs for all versions of the g5s plus... https://m.gsmarena.com/motorola_moto_g5s_plus-8699.php#xt1805
*You could always switch to the greatest US carrier ever: Sprint!
I think Sprint uses bands 25, 26, & 41 for lte(per this link: https://www.phonearena.com/news/Che...on-T-Mobile-and-Sprint-use-in-the-USA_id77933) & the xt1805 supports bands 26 & 41.
Yes, I am joking - but I thought I'd throw that out there as a possible last resort
Great question about the qpst tool to switch bands. I was wondering that myself as well. Last time I checked based on our chipset(msm8953) I didn't find too much...but I didn't look too hard TBH. I would search other device forums that share our chipset for that info...maybe you'll get lucky.

Yes, this was one of the things I tried. That code takes me to the 'testing' menu., where the first option is 'Phone information'. Entering that menu shows my IMEI, phone number, signal strength and a bunch of other options. My preferred network type is LTE/UMTS auto (PRL). In the menu in the upper right (the three dots), the first option is Select Radio Band. However, choosing this only shows one option, 'United States'. Selecting this does not change anything.
Thanks for recommending this though - I forgot to mention it as one of the things I tried.

Oops, what I didn't notice is you have the 1805. Mine, bought in the us, is 1806, and I have 5 options (if I remember correctly). Oh well.

That's strange as I've a lot of options there on Indian variant.
follow-up on modifying LTE bands
Just following up on this. After trying several ROMs (Pixel Experience, CosmicOS) I was unable to enter diagnostic mode to modify the bands, so I re-flashed stock. With stock I was able to get into diagnostic mode and tried modifying bands.
Using Windows 10, I had difficulty getting the Service Programming tool of QPST to work, and the NV viewer is deprecated in newer versions of QPST. I couldn't get a licensed version of QXDM, so I tried EFS Professional and CDMA workshop. The NVRAM value for item 1877 made no sense as the decimal was much larger than any other places I've seen and seemed to only represent three bands in binary. I decided to only try modifying NV item 6828 and 6829, since those control LTE anyway. The stock value matched the advertised bands for the phone - bands 1, 3, 5, 7, 8, 18, 19, 20, 26, 28, 38, 40, and 41 (decimal is 1786875085013, byte-swapped hex is D5 00 0E 0A A0 01). I added bands 2, 4, 12, and 66 (T-Mobile bands in the US) which resulted in a byte-swapped hex value of DF 08 0E 0A A0 01 00 00 02 (decimal 36893489934294190303).
The good news: despite not using a custom kernel, the values stuck on reboot.
The bad news: even with the new values sticking, I did not get LTE service. So either the xt1805 is actually missing the hardware for those bands, or something else needs to also be modified which is currently undocumented.
At this point I'm going to give up. If anybody has a use for an asia-pacific version Moto G5s plus with an unlocked bootloader, please contact me as mine is now a glorified paperweight!

Tried flashing stock firmware to overwrite with US variant radio; didn't work, still Asia Pacific (APAC) radio
Is is possible to "change the variant" from XT1805 to XT1806 to get US radio? Or otherwise install US radio version?
If not, does anyone have experience unlocking additional bands with QPST/QXDM on this model?
Finally, can anyone confirm if any custom ROMs contain a radio/modem worth trying?
The details:
While traveling my Nexus 5x bootlooped, so I bought a Moto G5S Plus (XT1805, dual-SIM, 3/32 edition, software repo is retapac) in New Zealand, naively thinking that it would work in the US since it's also sold in the US. Got back from my trip and the phone cannot connect to anything better than 2g (EDGE) (but oddly on layover in San Francisco LTE worked). I'm a T-Mobile customer and found that this phone lacks the key T-Mobile bands UMTS1700/2100 (band 4) for 3g and LTE1900 (Band 2) LTE1700/2100 (Band 4) LTE700 (Band 12) LTE1700/2100 (Band 66) for LTE. Now I'm pretty sure the hardware support is there, I just need to switch the radio to the US variant (XT1806). Of course I can't return the phone now, and Motorola reps were worthless (level one rep insisted no US phones work overseas at all!)
What I've tried:
I unlocked the bootloader and reflashed the latest (SANDERS_NPS26.116-61_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip) stock firmware from the firmware center. Upon rebooting, even though the firmware notes indicated a US version, it must somehow see that the phone is XT1805 and flashing the modem and baseband still resulted in APAC radio bands and no LTE signal. I tried also flashing the SANDERS_NPSS26.116-45-5_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC version, which worked except the gpt.bin file didn't install since it's an older version of what was already on the phone (validation failed due to not allowing a downgrade). After reboot and setup, I'm still on retapac with no LTE service. None of the firmware versions indicate a specific region, and this long thread leads me to believe the firmware is for all variants, so somehow it recognizes the variant on install.
Other Options
I know it's possible to also root with TWRP and Magisk and then install a custom kernel/ROM and use some special tools (QPST and QXDM) to modify the NVram to unlock additional radio frequency bands via this thread. I'm willing to try this, but I know it's risky and not fully documented for Moto phones (guide is for Sony). In the end, I don't really care about keeping the APAC bands - I'd be happy to just switch the radio bands to the US version.
I've read over 100 web pages and forum threads in the last few days researching this and looking for solutions. I'd much rather find a way to install the US version of the radio/modem and baseband, but if that's impossible, I'd be happy for anyone to share experience with unlocking bands on this phone. Finally, if these are not good options, can anybody confirm a custom ROM for this phone that includes a radio/modem so it doesn't use the existing stock radio/modem?
Thanks and sorry for the long post, just wanted to provide as much information as possible. Thanks!

even if u r able to flash modem of us u will loose ur imei. backUp ur efs partition first
Hi! I have the similar task with my xt1804, which lacks one of European lte band b7 (available in xt1805). Is there any possibility to unlock it for my phone? Please, share your experience.
same problem

Did ya try this
Dial *#*#4636#*#* to get to field service menu
Hit menu - upper right - then select band, I think, you'll see it - first option
Select usa - I think that was it - you'll see what I mean
But, I can't remember of hand what bands are supported by this device. Google will remember though, ask him!

I have the same problem with tx1805.. after flash baseband from a tx1806 i think that is a hardware limitation

I have the same problem
Hi ,
As I know, the mi11(M2011K2C) only support band28a, but my operater not support that.
I found when the LTE change to band28(LTE 700), the mi11 is swap from LTE to 3G(WCDMA).
May I disable the band? How to do that?
Thanks.

Go to settings- about- all specs- tap the internal memory until it opens the network test page- go to set prefer network type and choose the network types you want to have.
Or by Dial *#*#4636#*#*
Usefull for check connectivity, Dual Sim, IMS, etc...
Hi,
Thanks for the reply.
But in this method, only LTE can be selected, and the band in LTE cannot be selected.
Download activity launcher>phone services>set radio band mode(choose the 2nd one coz there's 2 radio band mode in results).
