M on AT&T/StraightTalk, GSM Frequencies, Verizon blocks?

I've heard that Verizon phones, though "global" are locked from the US GSM frequencies.
I'm considering getting a Razr M and using it on StraightTalk AT&T or T-Mobile prepaid.
It appears the frequencies should be fine. 850/1900 UMTS/HSPA + GSM.
Anyone have any thoughts on that?
I'll need to trim the SIM down to MicroSIM size, and get the phone unlocked, but besides that...?

Well it's an atom processor not A15, lower graphics performance by far, less apps in the market and can't get it in White.

See my post on your question in the Q&A board, and posts 18 and 19 in this thread.

Righto-,thanks. I read somewhere else (maybe it was you?) that the NV settings in the radio block MNC 230 (tmo) and 150 (at&t). There was a guy who had looked all through them and couldn't find where it was happening.
Is this MNC blocking something that would be remedied by buying the Austrailian version? I want an A15 CPU + GPU not the Atom one, simply because I like sticking it to Intel, and because I like the white phone not the black one.
Does the developer edition work with AT&T/T-mobile? Maybe I'll just buy that. This phone certainly is slick. I hope whatever fix we get will let us keep the stock ROM, always a bit more exciting (and stable it seems, usually) to me than CM(X)

As far as I know, the Australian one will work just fine with AT&T or T-Mobile (no 3G on T-Mobile unless you're in a refarmed area, though). Worst case, it's locked to Australian bands, and you need to get an unlock code to make it work internationally. The reason the Verizon ones are locked for US bands is because Verizon doesn't want you buying their phone and then switching to their competition. Telstra obviously doesn't have the same problem, since they're not competing with AT&T or T-Mobile. Of course, what I'm saying isn't guaranteed to be true, since I don't have an Australian M myself (but I'm trying to decide whether to import that one or the RAZR i). I'm like 99% confident you wouldn't have any issues, though.
The developer edition does not work on AT&T or T-Mobile, either. We should be able to keep the stock ROM. That's how it worked on my Droid Pro and other Verizon Motorola world phones. We just flashed a file that modified the baseband. There was even a file to flash that would return the baseband to stock. ROM flashes didn't affect the baseband once it was modified.
What I'm wondering is if it may just be possible to take the Australian radio and flash it to the Verizon M to make it work on our GSM networks. That would pretty much disable the CDMA radios, but we wouldn't need them anyway. I think some of the previous phones have gotten around the band lock by flashing a Chinese radio, so it seems like the same concept could be used here. I'm nowhere near smart enough to know how to do any of this, though. All we can do at this point (well, me anyway) is just let Team Black Hat and other Motorola developers know that we are patiently waiting for a solution.

Looks like I wasn't far off with my hypothesis. If the community can provide the radio image, we should know pretty soon whether it would work on the M or not.

It also works on the stock unrooted and unlocked Dev device so it should work fine on the stock locked bootloader devices.
Right now it appears to break eHRPD authentication when using a VZW LTE SIM with AU radio image. GSM service is fully functional with no modifications except the AU radio.

Well then...that pretty much settles it. I will be buying a Verizon RAZR M...Dev Edition if I can find one for a good price, or if not, a regular one. I hate that Verizon logo, but I'll save a couple hundred dollars by just dealing with it.

I've been searching for a way to buy this awesome phone in a *truly unlocked* state (bootloader + carrier), and it seemed to be, before now, that my best option was to get the australian one (it also doesn't have the ugly verizon logo on the front But, it's very hard to get it from here in the US, so getting the verizon dev edition and reflash the radio may be better. I'm currently with T-mobile, yes I know about the refarm ... I'll deal with that.
So, does anybody have a link for said radio image? freak4dell, have you gotten yours and tried to flash the radio?
Thanks, you guys are awesome!

Nope, haven't gotten mine. I'm out of the country until mid-December, so I won't be able to get my hands on one until then anyway. I am keeping an eye out for deals, though, so that if I see a good price, I can buy it and have it waiting for me.

Let me know if you find a good deal (actually, any deal at all) for non-verizon razr m! I've also been looking on australian ebay, there are a few auctions for the telstra razr m, but they don't ship overseas...
But back to topic: are the image files in these two following posts any good to flash the radio, or do I need anything else, like a complete telstra fastboot image, or something like that (re-noob-alert: I'm a dev, but I've never messed with phones before):

Also, these being "official" and probably signed radios (at least I hope they are), do I need to unlock the bootloader to flash them?
Note: I haven't gotten any phone yet, just gathering all the pieces together before dropping the cash
Thanks anyone!

No need, I just ordered my razr m developer edition from motorola.com We'll see how fast I can void my warranty
Speaking of which: do I need to unlock the bootloader (and void the warranty) to flash the radio? My understanding is that, since it's signed by the manufacturer, it should work without unlocking the bootloader. That way I can use the phone for a while and return it if it has any problems. Does anybody know?

Quick Question

Hello, I recently found a phone on Kajiji because I am leaving soon and needed it since my old one broke. Usualy I order my phones off Hi-moible. He told me it was unlocked so I assumed it was the international version,. I ended up with a 1337m, I am dissapointed since alot of the roms are only for that model. I was wondering as to why this is the case arent both phones identical in terms of hardware? How do you convert one to the other ?

That would be the Canadian Model. I believe if its unlocked it should still work, and the international Model is the one that actually has the least customization in terms of ROMS i believe mostly because of the Exynos processor. The I337M is the Snapdragon model which is the same Hardware as the US models. I use an I337M and load AT&T and T-Mobile roms all the time. Just make sure you choose T-Mobile Kernels for your device if using custom ROMS that arent T-Mobile based.

This phone the I9505 Why can i not use roms from this thread ?
I dont understand its unlocked and its the same phone what is the actual complication ?

[Q] ok, you guys. I really need your help. I'm very confused!

okay so when I bought my note 3 this article here, or review I should say, was very helpful. http://www.amazon.com/gp/aw/review/..._dp_cr?cursor=1&qid=1399409475&sort=rd&sr=8-2
the only thing is, I can't seem to figure out which note 4 model to buy now. if it helps any I live in USA Texas and I'm going to be using my phone on Net10 I would like to get 4G LTE and I'd rather have the Snapdragon model but the Exynos model is ok too. I just want to know which model would work best with the provider I'm going to use and get 4G LTE and also maybe not have so much bloatware. It HAS to be unlocked. Is there a USA unlocked version? What should I do... I'm really good with technology and phones don't get me wrong, but Samsung model numbers and figuring out what's what confuses the crap out of me!
all the unlocked models I found are either not compatible with USA bands or just that I'm worried because they're always European or Arab version phones and I'm just worried about getting one that's from some other country and that it won't function properly. Halp meh plzz?!

You will have LTE coverage on either the N910F(Snapdragon) or N910C(Exynos).Just get the one offered in your country.

Converting US version to EU?

In Nexus 5 there is a possibility to activate EU bands on US version. Can we expect it would be possible on 6P too?

I'd like to know this too. If its possible to activate band 28 on the US version for use in Australia by flashing a different radio (Are all the required amps and antenna things there)
I need band 3, 7 & 28 for LTE

Might not be possible , could be a different version of the radio chip that they use for the other version. would be nice if its as easy as just flashing radios but tend to think it will be more hardware

I was hoping this was possible as well! If it was and one wanted to flash a different radio do you need to unlock the bootloader to do this?
Thanks,
M

most of us are still getting our phones..give it a couple weeks

1) Anyone know if the radio-angler-angler-02.15.img contains ALL radios?
2) If I travel from US to Italy/Germany/Japan will flashing that Image get it done or will I need to do something else?

The US version of the Nexus will work in those countries except Japan without any extra work.

Am I right in thinking that if a specific band (i.e. 20, which isn't on the US version) isn't present the phone will simply use another band? Granted, this might not be LTE but still decent speeds.

Just check what radio frequency uses your carrier and check if it is available in the US model.
But if you buy it in the US, the price plus tax, plus shipping, plus tax in Europe, not worth it. Almost about the same price. Unless you have someone to bring it to you and you dont have to pay shipping nor europe tax.

What bands for each of the big 4 providers?

Anyone know for sure what bands each will have? I know the unlocked will have them all. Will every US version have all of the bands as well? Researching online for some reason right now is not giving me any info. The FCC filling for the unlocked U version is all I've found so far after a day of searching online.
http://www.androidguys.com/2017/03/...s-pass-through-the-fcc-supports-all-carriers/

I think I may have finally figured it out. Samsung hopefully did what moto and apple and nexus has done for years and made them all universal. I'm surprised nobody has mentioned this all before but here is what info I'm going off.
http://www.samsung.com/us/mobile/phones/galaxy-s/s/_/n-10+11+hv1rp+zq1xa/
T-Mobile
SM-G950UZKATMB
Verizon
SM-G950UZKAVZW
Sprint
SM-G950UZKASPR
AT&T
SM-G950UZKAATT
So the carrier versions are all the same just a different bloat package on all 4.
When an unlocked one arrives again the only difference might be less bloat.
This could be really good news for people who don't like contacts like myself.
Maybe faster updates from Samsung? I mean they can't possibly get slower than they already are can they?

They didn't. I have inside info from Samsung that it's the same as the GS7. They just changed the model numbering scheme to be more universally discernible. I was hoping for one phone with carrier customization but nope... they again made it impossible to get all features and bands on a different carrier.
The good news is the Verizon model doesn't have carrier branding any longer. I confirmed that today by unboxing an actual retail model.

So when do they finally release what bands each carrier model supports? Seems odd that no info exists on the phones releasing in 3 weeks. The unlocked model has all its bands published online but no official release date.

I'm curious to know if the Verizon model is the same as the unlocked one.

If you get it unlocked, insert a different carrier's sim, factory reset and it will boot with the splash screen and preinstalled apps of the carrier. I've seen the Att to Tmobile and verizon to att swap

That's interesting . I will try that when I get it. But I'm not sure that would effect the boot logo? I'm imagining it would stay the same, no?

I think your wrong. If you go check tmobiles website the software version is G950USQU1AQC9. There is nothing mentioning tmobile specifically there. I think that they will all come with carrier animation BUT be uninstallable.

I would hope so but I received this info from a Samsung Knox Development Manager who is an internal employee. I am crossing my fingers he is full of it.

I've got the bands for the AT&T and Verizon phones. Those companies had the decency to post the info online. Samsung chat was useless and told me some BS as usual about not knowing until the phone was released. Is it possible the T-Mobile bands listed on the website are the only bands it supports? 2,4,5,12?

If the websites are accurate and just considering bands alone it looks like the AT&T one has the best support.

I'm really Curious about exynos working on Verizon and can't find any info. I'm in Korea for another 8 months and was hoping to get the Korea model S8 and take it back to the states and use it on my Verizon network. I have a feeling it won't work just like the S7 did not.

The s8 Will be just like the note 7 was.... Internals are EXACTLY the same, just different SW, and can be flashed with any carrier SW to "make" them that carriers phone.
