[Q] Any difference between AT&T and DevEd radio?

When I converted my M8 over to the developer edition, I used the nandroid backup method, and then manually flashed the stock DevEd recovery so I could take OTA updates. I left the radio alone, though. However, I then let the DevEd install do several OTA updates, and now I see that my radio is up to 1.19.21331147A1.09G_20.57.4196.01L_F - which is not what the phone shipped with.
I have been reading in other threads that there may be differences between the AT&T radio and the DevEd radio, though from my reading, they always seem to have the same version number? (The thread I was reading hasn't been updated in a while, and stops at 1.16 radios)
The phone seems to work fine, but I'm curious if 1) there is any difference between the radio the DevEd install put on there, and 2) if so, is there any reason to go searching for a newer AT&T radio?

Newest AT&T radio is 1.19.213311491.A22G_20.51A.4198.01L_F
The Dev Edition OTA started rolling out slightly earlier (few weeks) than the AT&T OTA. Is there any difference? Who knows? I don't think anybody but HTC is going to know much about that. But as the Dev Edition is intended to fully support the AT&T network, I wouldn't worry about the baseband number being different.

Of the 3 releases to date, the radio has only been the same (between AT&T and Dev Ed) once: http://forum.xda-developers.com/showthread.php?t=2736921

My gut would say no, but if you want you can always try it and see if there is any difference (Speedtest, etc.)

I'm thinking no on that as well, as the phone is working fine as it is, and needlessly messing around with firmware seems unwise. If there was a definitive "yes", I might give it a go, but as it stands, I will probably let it ride.

I think the difference would be.
Dev Edition Radio - Open to all bands
AT&T Radio - Locked to AT&T bands. Roaming and all...Not just TO other carriers but FROM other carriers.
Can read up on Qualcomm's RF360 Front End Solution that came with the Snapdragon 801 chipset. It carries ALL the bands on there to make it "truly" global. However, obviously they WILL make some changes on a carrier level for like I mentioned before, roaming purposes i.e Money.
Both phones should be able to run all bands no problem, the AT&T one on the other hand, will have some locked out so that's the only difference I think.
Read up on it some more though, it's interesting stuff :good:

Unlikely that this is true. As already mentioned above, one radio deployed for the Dev Ed (1.14) appears to be the exact same radio number as the AT&T version.
While its true the radio hardware is capable of supporting all applicable bands (GSM/HSPA/LTE) used worldwide; that doesn't necessarily mean all are going to be enabled in software; or that they can all be enabled simultaneously. There may or may not be a software limitation, but I can only guess on that point.

HTC One m8 variants

Hi guys,
Planning to buy the m8 and root it. But should I be specific on the variants?
Im not from the US (The Philippines) so Most likely not gonna get atnt, sprint etc.
So my options are:
The international model
Emea (a friend of mine is selling his but it was bought in riyad, KSA)
Or the asian version (s801 2.5ghz)
Do they have like different model nos.? Different ruus / rom versions etc?
Had a bad experience when i bought a phone (m7 sprint wls) before, since im not from the us. Had limited roms available compared to the international version
Your input would really help

I would agree that you should not get a US variant. For one thing, they will be SIM locked. Another thing, the Sprint and Verizon versions are CDMA. Different software, and possibly different hardware (although its been discussed here, and not clear - but I would err on the side of caution and assume the hardware is different). So if your area does not use CDMA I would stay away from those variants.
All GSM versions, be aware that they can all be converted to another carrier variant once bootloader unlocked and S-off. So as long as you avoid the CDMA versions, you are good for ROMs.
I would suggest the version that supports your local 3G and LTE bands out of the box. But again, as long as you are willing to s-off the phone, you can change that in software. So if that is the case, I would just go with the best deal.
From what I understand, the Asian version is the same as any other GSM version, just with a slight overclock.

Well if you do go with a us carrier Verizon has the best coverage and thier phones are :not: sim locked. You can use them with any carrier anywhere. My second choice would be t-mobile

The OP is from the Philippines. They aren't going to use a US carrier.
I would advise against CDMA variants for the reasons already mentioned.

Thanks guys, I just want to be clear, so if I use a Rom or RUU on a GSM variant, as long as Im'm on S-Off / Unlocked Bootloader and/ or on SuperCID. I could use any Rom ./ RUU from different GSM variants (I checked the rooting guide for the M8 and is similar to the M7, so as far as unlocking the bootloader / root that I have an idea).
Do they have different RUUs at all??

Yes you're right.
I thought all has ruus on it. But with supercid i could use any nandroid backup right? As long as its gsm
I think I will go for the Asian version (wwe right? Cause it has a higher clockspeed and updated s801) And go supercid and use international (gsm) roms. Will that work?

HTC One M8 of Choice?

I am looking to buy an HTC One M8, which would the community recommend? I am on AT&T but I love to root, and install CM, and other ROMS to any phone I own. Which Variant would be best for me? Or are they all supported under CM and custom recoveries? Thanks!
Also if anyone has one on the cheap let me know

For the most part, I'd say whatever variant you can get for a good price. All the M8's (known as "GSM M8") are the same hardware internally aside from the following exceptions:
1) Dual SIM M8
2) Verizon/Sprint variants. These include CDMA radio, so different hardware. No benefit for you on AT&T, and less selection of ROMs.
3) Taiwan variant. Hardware is the same, but its overclocked out of the box. Some software from the other M8 versions won't work on this variant (including radios).
Aside from the variants above, all the M8 versions are essentially the same hardware, with minor differences of exterior color availability, and carrier logos on the back of some. Once bootloader is unlocked (and preferably s-off) you can flash CM to any of the versions.
One thing to note, AFAIK any M8 that has hboot 3.19 cannot be s-off by sunshine (and that is the only s-off method). Band compatibility for the various carriers/regions is software based on the M8. However, if you need to flash the radio to change band compatibility on a non-AT&T M8 variant, you will need s-off to do so. So unless you have a way of knowing what hboot is on the version you are buying, I tend to say that you might want to choose either the AT&T version or Dev Edition, to guarantee band compatibility on AT&T's network. Both of which fully support AT&T bands out of the box.

Right so, Verizon M8 wouldn't work on AT&T? That sucks. I knew Sprint wouldn't but Verizon is nearly compatible with AT&T by now, so thats sad lol
The best price is the Sprint variant, but thats because sprint phones do not have high resell value at all. People hate to deal with them completely and that solely makes the value go down...
I have not looked at the other variants but I will check them out! Thank you! I repaired a One today, It was a lot of work, but nearly any HTC Phone never looks or feels the same after a screen repair, because of that uni body.

Verizon variant will work on AT&T GSM and HSPA network (in addition to being SIM-unlocked out of the box); however, it doesn't have all the LTE bands to work on AT&T in all regions. And while the "GSM" variants can have radio software flashed to change band compatibility, you can't do this on the "CDMA" variants (at least you can't flash a GSM radio on a CDMA variant to open up all the needed LTE bands).
Similar situation on Sprint version. Except I think the Sprint comes SIM locked out of the box (you will need to get it SIM unlocked). And also the LTE bands are different from the Verizon version, but still not all the bands needed to work on AT&T in all regions.
My point in highlighting the hardware difference (CDMA versus GSM variants) is not only are the radio basebands not interchangeable (as mentioned) but neither are the ROMs. For the CDMA versions, you should only flash ROMs that specify that version is supported. The GSM versions can flash any of the GSM ROMs, and there is a much wider selection.
Again, there isn't a benefit to either of the CDMA variants (for use on AT&T), and several critical downsides, so I generally don't recommend them to basically any user that isn't on the specific carrier (Verizon or Sprint).

True, if the device is being sold second hand, you can (and should) always check to see if its already s-off.

Aside from the exceptions previously listed, all GSM M8's are the same hardware, and firmware should be interchangeable (with s-off). T-Mobile version should be able to flash WWE firmware. Although, if you want to be prudent, you can check and confirm to see if any T-Mobile owners have done so successfully.

[Q] US phone - 4G

Hello.
FIrst , i know there are 2 more threads ( or maybe more , i could only find 2 ) about this but they didn't made me understand my problem.
So I live in Europe and my M8 is an US M8 ( Canadian if i remember right) and because of that 4G isn't working here , in Europe.
Now my question is : Can I do something about this ? I'm s-off if that can help..
Thanks.

Check if your version of the M8 supports the 4G band(s) used by your carrier. If not, the band support can be changed by flashing the appropriate radio.
Also, make sure you are using the proper APN for your carrier. Sometimes carriers use a different APN for 4G enabled devices.

1) Verify what version of the M8 you own
2) Check specs online to see what bands your M8 version is supposed to support
3) Find out what 4G band(s) your carrier uses
You haven't given much detail, and I don't know your knowledge base (what you do or don't know how to do). So I can only give general steps, and rely on you to ask specific questions on the steps above, as necessary.
Flashing the radio appropriate for your region/carrier is probably going to fix the problem. But I recommend you do the research above first, to first confirm that band support (missing in the device software) is the issue.

Yeah , looks like my brain wasn't working when I wrote you later.
I have a T-Mobile M8 and their bands are 700 , 1700 , 2100. For my carrier I need 800, 1800 , 2600 so looks like I need to flash a radio.
I just did a research and found some radio here on xda but i don't know which one to download. ( If you can help me here i would be very thankful )
My phone is s-off so i'm alright , i just need to change my cid to supercid.

Yeah . I know Canada is not a part of the US.

Do you intend to run a custom ROM, or keep the phone stock?

I already have a custom ROM - ViperOne

@redpoint73
So can you help me in finding the radio for my M8 ?

If the latest Viper (version 4.x), I would suggest flashing the 4.16.401 firmware package. Not only to get the Euro radio (with the LTE bands you are looking for), but all the other firmware modules that correspond to the 4.16 software, for most bug-free performance.
http://forum.xda-developers.com/showthread.php?t=2696282
s-off is required (which you state you already have) to flash another region/carrier's firmware. Plus, you will need to change to the proper CID and MID.

That isn't the firmware number.
The term "firmware" is a little confusing. On this device, when most folks say "firmware" (including the link I sent you) it refers to a package of modules including hboot, radio, WiFi, Bluetooth, and others, that DO NOT get flashed with the ROM (but are critical in the correct operation of the ROM).
Firmware does not in fact really have a "number", so referring to the software (OS) number that the firmware deployed with is the best we can do. So again, its confusing.
The OS number is bootloader just tells you what software number the current ROM is based. Flash a ROM with a different base, and that number will change. But the hboot, radio "firmware" will not change. Therefore you want to have firmware that corresponds to your ROM.
There is in fact no easy way to tell what firmware package you have installed. The best way is to look at the hboot and radio numbers. So tell me what those say on the hboot screen, and I can probably tell what firmware you are on (although I'm not that familiar with the T-Mob radio numbers).
If you read the thread I linked, it explains it a little further under the big red letters.

The radio number would suggest you flashed the Android 5.0 firmware, not 4.4.4.
Check the APN again. Does it match the APN on the "other" phone?
If the 4.16.401 firmware, and running current Viper, and right APN, I don't see a reason why LTE won't work. You might check the Viper thread to see if there are any other reports of a similar bug.

The APN is good. I'm gonna check Viper thread but probably I'm just gonna leave it like this. I'm gonna buy the M9 anyway when it's available here. Just wanted to make 4G work untill I buy it but yeah. Thanks anyway for your big help Have a good day/night.

What country are you in, specifically?
I think there were a couple countries (mostly Eastern Europe, I think) that had some data issues on KitKat, but I think they had some minor radio updates. And I would think those issues would have been cleared up by now (for Lollipop).

New to Oneplus

Hello, I am soon to be new to the one plus scene, and had a few questions.
I got the factory unlocked 7t and plan on using it on tmobile. Am I going to have rcs messaging? Will it be limited in any way? Also I have read that you can flash to international from tmobile but can you go the other way? And final question going either way does it require root or anything or because they are stock images they work fine?
From what I can tell from where I purchased it says HD1907 which is the tmobile variant(or should be?) Listing and reviews say confirm getting the HD1907, and its factory unlocked without branding. Can it be branded? And I should be fine and able to go to international/de-brand if I decide to later?

Welcome to the OnePlus 7T, it's a great phone!
I suggest reading through this guide to flash from T-Mobile to Global: https://forum.xda-developers.com/oneplus-7t/how-to/guide-t-mobile-brand-conversion-to-t4019495
It will walk you through the entire process of flashing your phone and (if needed) rooting it as well.
Personally, I'm a big fan of the All-in-One Tool found here: https://forum.xda-developers.com/oneplus-7t/how-to/tool-tool-one-driversunlocktwrpfactory-t4103515
It does just about everything you could need in terms of flashing, rooting, returning to stock, etc.
No matter which guide you choose, both forums are very active and should be able to help you if you run into any issues.
In regards to the RCS messaging, you should be fine but don't hold me to that. I typically use Google Voice but I know that Google Messages supports RCS on T-Mobile.

I suggest reading through this guide to flash from T-Mobile to Global: https://forum.xda-developers.com/oneplus-7t/how-to/guide-t-mobile-brand-conversion-to-t4019495
It will walk you through the entire process of flashing your phone and (if needed) rooting it as well.
Personally, I'm a big fan of the All-in-One Tool found here: https://forum.xda-developers.com/oneplus-7t/how-to/tool-tool-one-driversunlocktwrpfactory-t4103515
It does just about everything you could need in terms of flashing, rooting, returning to stock, etc.
No matter which guide you choose, both forums are very active and should be able to help you if you run into any issues.
In regards to the RCS messaging, you should be fine but don't hold me to that. I typically use Google Voice but I know that Google Messages supports RCS on T-Mobile.

First thanks for the quick response, as a past dev im familiar with xda and have been looking through the 7t section including those and im starting to getting familiar. Thanks for the recommend!
I suppose the question I still don't get is the listing is for a tmobile unbranded so does that mean its on global or not? is it on us, not global, but just not branded but other wise 99% similar to branded just lacks carrier apps? Is there a step in between carrier branded and global? Does tmobile varient + unbranded just means it has the straight from OP firmware? If thats the case does that mean it can accept the tmobile branded firmware? I know everyone is like go global it seems but just for the sake of understanding I want to know since its tmobile varient hardware can it go back from OP updates(if thats what its on) to tmobile? and still be bootloader locked?
seems like there is several steps
carrier branded > carrier unbranded(straight from OP?) > global
However the update on OP's site doesn't list a different global download? How do global users get the update? or am i missing that theres a us site section and a non us site section?

There are a few definite ways to find out:
Model Number: the T-Mobile version is HD1907. I have the International version (HD1905) which has dual sim slots (the T-Mobile version only has 1 sim slot available)
Is there a T-Mobile splash-screen
Are there any T-Mobile (pre-installed) apps
If you have the T-Mobile version, it will never have the original OP software unless you flash the International ROM.
It sounds to me like it's a T-Mobile version (HD1907) that's been unlocked and (probably) flashed to the International (global) ROM (which will get you the official OnePlus software as it comes without the T-Mobile carrier bloat, which is really pretty minimal. I think it was 2 apps when I had the T-Mobile OnePlus 6T).
If you decide to re-lock the bootloader, I'm almost 100% sure that you must be back on the original software that the phone shipped with. So if it's a T-Mobile version, you must flash the T-Mobile ROM before you re-lock the bootloader.
No matter which software you have, it's really pretty easy to go from one to the other, especially with the All-in-One tool.
Personally, I prefer the International ROM (or their Beta Channel) because of faster security updates.

There are essentially 3 ROMs direct from OnePlus that you could flash (aside from the T-Mobile version)
HD65AA Global (which is one I would recommend)
HD65AA India
HD65BA Europe
All of which are found here: https://forum.xda-developers.com/oneplus-7t/how-to/oneplus-7t-repo-oxygen-os-builds-t3997037

So as long as it is infact a HD1907 I can use the builds here to go back to this models stock and then bootloader lock? would this be the best way to do so?
Edit: so the about info says HD1907 it didn't say tmobile when i started it the sim tray hold 1 sim. (just arrived) so I should be able to put it back on tmobile branded and lock the bootloader yes? I didn't actually confirm that its bootloader unlocked but im assuming since about info says its tmobile but appears to not be tmobile branded.(unlocked bootloader is only way that could all be true) The packaging was all completely sealed which is why im just a bit confused still as how it can be a tmobile variant but not be tmobile branded but also not modified outside of the factory?

so it looks like its 10.0.10.HD65AA rom, model HD1907, device state locked. so to go back to tmobile stock would I have to unlock? then do something like in this guide https://forum.xda-developers.com/oneplus-7t/how-to/op7t-t-mobile-unbrick-tool-to-restore-t4004005 ?

Just wanted to say thanks for the info! I was able to unlock bootloader(not sure if i needed to but did) flash the tmobile branded from https://forum.xda-developers.com/oneplus-7t/how-to/op7t-t-mobile-unbrick-tool-to-restore-t4004005 after doing that I looked in bootloader and it says device status locked so im all set.(nice to know that I also have global as an option among others) Thanks again!

Glad to hear it went well. Aside from a more recent security update, I don't know if you'll see any difference between the T-Mobile ROM and the International (global) ROM so enjoy it.
I know some folks wish there was more development for the OP7T but it's really pretty solid. Oxygen OS is smooth and Android 11 should be available for it by the end of the year. That being said, I'd love to see how the Paranoid Android ROM runs on this device! Hopefully that'll come soon.
