The Atrix can't use 4G on tmobile.
Can the new roms with the unlocked bootloader change the radio frequencies to work with tmobile's network?
or
Is this a hardware problem?
No unfortunately it is a hardware limitation.

Yep, the ATRIX radio doesn't have the band needed for T-Mobile 4g.

Im having the exact same problem. Except im using an ATRIX on att :/
Is there a prepaid service that could provide 4g or at least 3g speed for the Moto Atrix?

Are we sure it is hardware? The specs say qualcomm mdm6200 which via software (as per the qualcomm data sheets) is able to use umts 1700/2100 bands(ie AWS bands).
Let me grab the links.

Qualcomm data sheet. http://www.scribd.com/mobile/documents/54154049
On the Qualcomm datasheet, I found frequencies beginning on page 111.

I was reading the pin outs and that is where I determined that there are no seperate pins for AWS or well any band and so I would assume the frequency is baseband determined.
If anyone is still looking. Pages 102 through 104 is interesting as it gives the pin outs that need to be programed in software for the correct bands. If anyone knows how to break open a radio firmware or program the radio that would allow us to get all bands working I think. This would also possibly allow for targeted radios that use less energy since they only rx/TX on the frequency that is available in that location.

Hi, despite the availability of the International 4g version of the X1 [7d-501L] in italy, that has all the LTE bands that I need, I bought the chinese 4g variant [7D-503L] in order to receive more and quicker updates.
Now, AFAIK the two versions are indentical in hardware, could a developer extract a modem from the international version and make it a flashable zip that we can put on our chinese 4g variants?
This way we could have the chinese 4g version with all the latest ROMs, but still enjoy FDD-LTE in Europe and rest of the world.
Sorry but it is not correct. The international version has a modem with only fdd frequencies, while the chinese version has fdd AND tdd. So, different modem.
You can search this area and you will find at least two others who have tried to do this, unsuccessfully!
I meant that the chinese version has a ton of TDD bands and only 2 FDD bands. Yes the modem is different, but I believe the difference is in software, not in actual hardware.
Hello you can flash 501l firmware on 503l device without any issue, for me. But I think hardware are not the same, 800mhz fdd LTE band is not present on 503l.

I don't need that. I bought 503L to have all the latest rom, it wouldn't make sense to flash an older firmware. Yes 800 mhz is not present on 503L but I *strongly* suspect that it is disabled by software.
I really think that 501L and 503L are the same, the only thing being that Huawei enables certain bands on one, and other bands on the other one.
Yes I understand and it would be great. But when I flash 501l, I should have 501l modem? Maybe it is a hardware switch?

I agree with you that hardware wise, all the different variations of the X1 are identical. Difference is software/firmware based. The difference is located in a partition that is usually not flashed by a ROM update. I successfully did this with my AT&T Samsung Note 2 and unlocked TMo AWS bands with the help of XDA instructions.
To assist you, I came across this website/blog that has instructions on how to unlock FDD bands on 503L. I have not tried it; I live in the US, even unlocking the FDD bands, I will not get LTE (main US LTE Bands are 2,4,17)

Hi all,
I got my sprint Moto E a few weeks ago. Its working international, but the problem is that its locked to 2G only.
I think its the radio that is locked.
I had a smilar issue with my HTC one E8 sprint when it was updated to Lollipop where the #G part of the radio was disabled. I used this method here to unlock the UMTS900/UMTS2100 portion.
to do this with the Moto E, I need the SPC code to program the baseband. I have had little success with the SPC. If anyone can assist, maybe we can make it a global phone

If the spc code was obtained, would following those steps allow it to be used with any carrier?
The spc code is unique to each phone. If I can get spc code for the device I currently have, a solution is possible

can you let know if you had to do something special to get it unlocked for gsm use internationally or is it unlocked out of the box.
Also would you recommend this phone or lumia 640?

Based on my experience with this phone, (Moto E 2015 Surnia xt1526,) I think that the lock on this thing is in the modem. Im not 100 percent sure though.

I haven't been around here long enough to have come across it - do you know if the modem files are typically flashed with ROMs on this device? If so, can we swap out modems between custom builds with little or no issues? I don't recall seeing a modems thread, so I'm assuming they aren't typically flashed separately.
I still don't plan to get a CDMA sim card, but I do have sim adapters coming, so I can see what I can get working with my AT&T sim.
Maybe I will be chasing LTE issues after all - really having fun messing with this device.

I know that it does use modems, as far as I'm aware, it has 2 parts, fsg and the Helios h.bin thing. As for switching them out in a custom build, I'm probably going to test it.

OK, those are both new to me (this is my first Moto smart phone) but gives me a place to start looking. Sounds like from what you said that all these ROMs include modems (some devices I've been on ROMs typically did not, modems were flashed separately as needed).
Sent from my SAMSUNG-SM-G920A using Tapatalk
Custom ROMs do not come with their own modem's, they utilize the modem that was present in stock before you flashed. The carrier lock is definitely in the modem though

If I might add, i am wondering if we could flash a modem from the us retail version or other and maybe remove the lock? I don't know if it would work, but there is always a small chance it might. Another option might be to have someone on a gsm variant to pull the modem files and maybe we could flash that in fastboot? I don't know for certain, but i think it might work. If it doesn't, then the lock must be elsewhere.

Do the GSM variants have hardware support for the same radio bands as the CDMA models? If not, I'd guess flashing GSM radio on CDMA device won't be a good idea

The question of whether the Korean 256GB models (SM-N950N) of the Note 8 having the 1700MHz / Band 4 support or not was in question due to the limited info. online, not showing these bands listed early on...
However, it looks like now that people have the 256GB Note 8's in their hands, many have proved that the Korean variant does indeed have 1700MHz / Band 4 to work 100% on T-Mobile....ie... Full support of all the Bands. (Less the 600Mhz, which is only available on the LG V30 as the first phone so far to feature the new frequency. That's for another topic...
Can those of you who have the 256GB model on T-Mobile, confirm how it's working along with some screen shots of speedtests etc?...
Thanks...
What about Band 66 which is the 1700/2100 one.

Looking at the 4G Specs here:
http://www.phonemore.com/samsung-galaxy-note-8-sm-n950n/specs/3552
It appears it does support both 1700MHz and 2100MHz frequencies, though it doesn't specify band 66. It states it supports these:
LTE Cat16 700/800/850/900/1700/1800/1900/2100/2600 (Bands 1,2,3,4,5,7,8,12,13,17,18,19,20,25,26,28)

If you want to reliably verify what bands a Samsung device has my advice to you would be to go to the Samsung website located in the regionn or country that the device is sold in.
Then navigate to the N8 on that website and check the specs.
I've learned never to trust what those third party websites state. Especially frequency check.
Here, I've googled it for you...

B66 is not important for most people on Tmo USA. Google it & see if it's even available in your area. B66 is an extension of B4 & currently not available in a lot of areas. B71 will probably be more of a difference but Note 8s don't support it anyway.
Generally B4, B12, & B2 is what will be primarily used. N950F supports B66 but I've never seen my phone connect to B66 anywhere around me.
Thinking about buying this phone. Can you guys tell me the common issues with this phone? The one I'm most concerned with is the headphone jack, does it produce hiss sound at low volume? I ask this since I came across a lot of phones with that issue. Thanks in advance

I personally don't experience hissing on this phone. As far as issues, it involves the OTA from Vendor Roms which bricked some devices. You can check your ROM version and cross reference it with the ones on the Mi website to make sure. Aside from that, I don't see anything wrong with the phone.
Hi, I'm also considering to buy Note 5 and I just wanted to say that I don't have that problem with Note 4, it doesn't mean much since I don't use N5 but I think there is very very little chance for hissing issue in any device produced in 2017.

Hi, when I purchased seller offer also a global variant for 40 usd more.
Many people confuse about global device version and global firmware that it´s not the same.
You just have to pay special attention to the bands that is enabled, the global version has more bands enabled, by i.e my version that is a non global doesn´t have LTE bands 2 (1900) nor 4 (1700/2100) it mean that in my country it can´t work on 4G (of course I bought it so it is cause I didn´t need). This is the main difference.

Why do you say that has B4? Where you saw it?
Look at this info, just 4G apparted, this is a non-global version from a chinese seller you can find these specs;
4G FDD LTE B5:850 /B8:900 /B3:1800 /B1:2100 /B7:2600
TD LTE B38：2600 /B39：1900/ B40：2300 /B41：2500 MHz
TD or TDD is the LTE FOR China, look up FDD LTE bands.
And this is a Global version, seller usually put in a red highlighted the bands added
4G: FDD LTE B5:850 /B8:900 /B3:1800 /B1:2100 /B7:2600 /B4:1700 /B20:800;
TD LTE B38：2600 / B40：2300
Differences here are bands 4 for Latin America and guess some regions of Asia and maybe others and band 20 for Spain.

No, if your device hasn´t these two added bands definitely it´s not a global version (global rom concept mean nothing for this) is a hardware limitation although can work within 4G depending on your company carrier in some of the 5 frequencies enabled.
I have a Chinese RN5, it has loads of bands dudes. The chance of it not working on your network are slim.
As for the headphones dilemma, they do not hiss or produce low volume. Altho if you pair them with Xiaomi Pro HD which have a high impedance then you will notice a lack in volume. That can be easily fixed with Dolby Atmos the Magisk Module.
