hello guys
im planning to buy htc m8 from a guy, the phone has verizon brand on it and the question is: is there any difference between the international m8 and verizon one? and can i flash the official's one rom on the verizon's one? and in general, is there any hardware or sofware difference?
The Verizon and Sprint models are different hardware, due to the CDMA (plus GSM) radio. All the GSM versions of the M8 are essentially the same hardware, but the CDMA versions are the exception. Trying to flash GSM software onto the Verizon version won't work, and might even brick the phone. I'd stay away from the Verizon version, unless you happen to need CDMA (not likely in most parts of the world outside the US).

Thank you man, you saved me, i apologized to the guy.actually, one of my big concerns is custom roms, i ordered my 4g note 3 from outside my country just because it has more support.
Thank you again man
I recently won a m8 in a contest. And through lots of searching I'm stuck, I live in the UK and my phone is from the US. I want to know if my phone has the right hardware to get lte on bands 3 and 7 as I'm on ee. But I cannot find out anywhere what hardware is inside the device, any suggestions? Thanks.
Check the preferred network (in settings) if you can enable lte connectivity.

LTE Bands
Hi!! a have the HTC One® Developer Edition (M8) and this supports the followings Bands in LTE: LTE Quad Band (Bands 17/4/2/5).
Check the exact model of your M8, with this tool: https://play.google.com/store/apps/details?id=org.tritonsoft.cidgetter&hl=es-419
Cid code is needed to find your exact model and get the description of networks supporting.

Any carrier branding (Verizon, Sprint, AT&T, T-Mobile) on the outside of the phone or on the OS (splash screen, etc.)? Mosts US M8s are branded, aside from Dev Edition, unlocked, or GPE.
As long as its a GSM M8 (Verizon and Sprint are CDMA/GSM) in theory you should be able to flash a different radio to get the proper band compatibility, even if your model doesn't officially support the needed LTE band (unlocking of bootloader and S-off required).
Verizon is going to let me choose between an unlocked phone and developer model phone. Which one should I choose? (in terms of ROM support, ease up update access, root...etc)
Nevermind, its unlocked version only. I get to try the phone out and see if it is still plagued by the blurry, color/light bleed/auto focus issue or not. If it is, they will let me get a Note 4

How is that going to work the dev and unlocked m9's are supposed to be gsm only meaning no cdma ? And the LTE bands for verizon are not supposed to be enabled on the non verizon versions of the m9 ?
Actually all the verizon m9's are unlocked because verizon does not sim lock phones any more they just lock the bootloaders and wont let htc dev unlock them.

Technically, All newer phones have both GSM and CDMA radios. The Qualcomm chips (from what I read) have both radios in them already. My dad has a GS4 (CDMA) and is on a GSM network in Israel. So, saying this, it only makes sense that it should be able to work. It's just weird
Ima tearing a new butthole into Verizon because of all the bullcrap they've told me (I don't know enough about the unlocked models), so you could probably count this as more crap. However, they did also offer a Galaxy Note 4 at a discount (on edge). If I get that for a total of 650 (instead of $600 for M9) or $600, should I? I love the M9's speakers with a strong passion, but I do like the bigger screen and higher resolution...let alone the better camera...I read into mods and of course with Knox and all..I dunno about root.

Ok so lets say all of them have cdma built in and your right, so then how do you get the bands enabled for verizon LTE on a gsm m9 such as the unlocked m9 sold by htc directly ?
The posts about this on the m8 all required s-off to enable other bands such as enable the bands on a verizon m8 to get Tmobile LTE and then people still had issues having to toggle airplane mode all the time to get the Tmobile LTE back working on their verizon m8.
I had tried and tried to convert my verizon m8 to a dev edition like people did on the gsm versions which they all could but no one ever figured out how to get it done.
So my ultimate question is how would they get verizon LTE bands enabled on a gsm based carrier unlocked m9 that is not s-off ?

Oh and tear into verizon all you like bro let me help with that lol as I hate them as much as you do.
And I think the sammys have the bands enabled for basically all LTE in all the major carriers like the nexus 6 so they can run on any network.
I think they should require all phones to work on any network just like the nexus 6 so one version can work on any network, I guess we can dream right that would be my only complaint with htc that they dont enable the bands for all networks here in the USA.

1. You are probably right about the T-Mobile thing, but it IS T-mobile. I don't even think they, or sprint can keep up with the big boys. So If I got the GSM unlocked...and did the paypal buy over a year option, I wouldn't re-activate on Verizon for quite a while. I plan on going to Israel so I don't need a CDMA device for a while...Even so, the M9 has the bands for all of the networks, last time I checked. Saying that, I will already have S-OFF because it would be a dev edition, or the unlocked version that I would just S-OFF through HTC Dev. Saying ALL of this, even if I do come back to USA and CAN'T be on Verizon (whom I think is better then ATT), then I could go ATT. Ya know? That is IF I came back to the USA. So what do you think now? (With more information about the situation).
Hello, I bought from eBay Htc one m9 and today I have got the phone and I found that's is an M9w model.
I can't find any info about this model so I thought maybe some one here knows..
Thanks.

It's China version. You can see CID is HTCCN_701. Can use wcdma/FDD LTE/TD LTE(Band 39 is not support).
Use 810 Ver 2.0.:silly:

So, this is a GSM version isn't it?
Is it safe to put a international (401) or unlocked (617) ruu?

This somewhat gets me confused.
I bought a used one with s-off condition, and found it was using stock marshmallow sprint firmware (651).
If it's gsm only, then wouldn't it have an issue with sprint firmware,which is for CDMA?
After reading a lot, I was under the impression that you can't switch firmwares between gsm and CDMA.

Yikes - pretty sure you can't, and that trying is a great way to brick your device. I'd guess that the model you have is somehow a CDMA version. Perhaps you could post some device information for us to research to help you determine exactly what you've got?

Thanks. I also thought that should be the case as well.
Anyway, this is from fastboot.
Code:
(bootloader) kernel: lk
(bootloader) product: htc_himawhl
(bootloader) version: 1.0
(bootloader) imei: 3572xxxx453xxxx
(bootloader) version-main: 3.41.651.21
(bootloader) boot-mode: download
(bootloader) version-baseband: [email protected]
(bootloader) version-bootloader: 1.0.0.0000
(bootloader) mid: 0PJA20000
(bootloader) cid: SPCS_001
I'm aware that mid and cid could be changed using fastboot commands, but I never heard about changing the product field if this is really m9w version.
Anyway, I checked the imei with the box, and it matches.
The label on the box says it's m9w.
If i checked based on active bands, it is a cdma phone with only sprint 4g bands available, but going by imei (checked on imeidata.net), I got the bands are supposed to match witth the international model. I don't know how reliable that site is, though.
Code:
GSM 1800, GSM 1900, GSM 900, GSM850 (GSM800), LTE FDD BAND 1, LTE FDD BAND 20, LTE FDD BAND 28, LTE FDD BAND 3, LTE FDD BAND 5, LTE FDD BAND 7, LTE FDD BAND 8, LTE TDD BAND 38, LTE TDD BAND 40, LTE TDD BAND 41, WCDMA FDD Band I, WCDMA FDD Band II, WCDMA FDD Band V, WCDMA FDD Band VIII
Would that data be sufficient to see anything strange?
A little digging turns up that sprint spark is the most likely carrier using td-lte.
Cdma devices dont have a sim while gsm devices do. That's why you can't xflash. M9 gsm sort of does both.

It depends.
If your network is "sprint" then you need to check if the phone has a sim card port. If it does then you have a gsm phone. If not then it's cdma.
Sprint also does gsm phones but the question is "how do you know if the firmware you're downloading is cdma or gsm?". Because you CANNOT cross flash a cdma firmware to a gsm device or vice versa.
So, presuming you DO have a sim card port it's gsm for sure so you can treat it as a generic gsm device BUT sprint are known for making their devices difficult to work with, but that could be cdma devices.. So yes, with gsm you should be able to mess with it to flash stuff but make sure you make a backup the very second you get into TWRP (everything except data) and, if you can, make the files available to flippy for others to recover their devices (your contribution for the help you have had and will get?). I can host the files forever on my gdrive with my m9 backup if needed and flippy will add them to his help thread in the general section.
So, by common locigal deduction, we don't know for sure but now you know how to tell if it is gsm or cdma but still be careful with firmwares as one mistake = a doorstop.

For what it's worth, the SKU you're software is reporting is 651 - that's definitely a CDMA version (Sprint).

Sprint-branded M9s are always CDMA devices. Since LTE exists CDMA phones use sim cards as well. Please be carefull with such posts as the one I quoted. People might think they own a GSM device although they don't.

Sorry, not 100% true at all. Sprint have sprint spark which is td-lte and uses gsm devices. I did extensive research into it last night.
If the cdma phones use simcards then those devices are gsm. Cdma devices are tuned at the factory for specific networks hence the lack of simcard slot. Simcards support gsm and the m9 with a sim doesn't support cdma but instead wcdma along with all the gsm bands too.
So I'm willing to bet a testicle. You?.
Beamed in by telepathy.
In short, I think this means, sprint is giving me a hard time lol.
So, just to summarize:
- From the box and imei, it seems I have m9w model (GSM)
- According to firmware, and available bands, I have sprint network (CDMA)
- Judging by the availability of a sim card slot (the provider I am using is GSM), it's definitely GSM capable.
So, going for that, it seems that it really is a CDMA model, just with different brandings?
Am I right?
As for the backup, I don't mind sharing it, though I don't see much benefit, since I have tried a sprint RUU, and it works fine.
I also used ViperOne and using only Sprint kernel would make it be able to recieve network signal.
So, I think it's safe to say that the one I am using one of Sprint variant, so I should be careful when cross-flashing.

SIM cards: Before the advent of 4G LTE, the obvious difference between GSM and CDMA devices were with regards to the SIM card.
[...]
You may have noticed the latest smartphones intended for CDMA networks also coming with SIM card slots, to take advantage of the network’s 4G LTE capabilities. While GSM and CDMA devices cannot be interchanged even now, and will never be cross-compatible, that won’t make a difference as we continue to make a push towards 4G LTE.

Many Sprint and Verizon phones now have SIM cards, but that isn't because of CDMA. The SIM cards are generally there for Sprint's and Verizon's 4G LTE networks, because the LTE standard also uses SIM cards. The phones may also have SIM slots to support foreign GSM networks as "world phones." But those carriers still use CDMA to authenticate their phones on their own home networks.
[...]
The problem is, they're turning it on in different frequency bands, with different 3G backup systems, and even, in the case of the new Sprint Spark network, using an LTE variant (TD-LTE) that doesn't work with any other U.S. carrier's phones. There are very few phones that support all of the carriers' LTE bands.

The Sprint M9 is not a traditional CDMA phone but that's due to LTE being a GSM technology and therefore requiring a sim card*. Nevertheless it's still CMDA enough for not being compatible with GSM firmware like the dev edition (617) or the wwe version (401). My statement is still valid. If you tell people every phone with a sim slot is a GSM device they may try to flash GSM RUUs on CDMA devices and brick their phone this way.
* Well, and because CDMA carriers probably understood that their phones need to support at least some GSM bands if they don't want to lose all customers who travel to other countries where CDMA most likely isn't supported at all.
Edit @shaqman89: Can you please take a look at the bottom of the backside of your M9? HTC engraved the model id at this place on the European WWE version. I don't know for sure but I guess that this might be the case for the other versions of the M9, as well. If you own a sprint M9 you should find "0PJA200" there. (The engraving lacks two zeros if you compare it with the MID that you get with fastboot getvar.)

You are right. It's really faint and small, but there is a model id there.

I owe you a testicle but I have no obligation to pay up on the clause that neither of us actually know what the hell is going on.. [emoji12]
But, what does that mean for the m9w?. Have we established that its a sprint phone and the regular firmware is ok or does it have an alter ego like jekyll and hyde?. Is there an easy way to find out if it'll be locked out, like branding etc.. Can you use any sim for any network?. A test on a 3g only network could reveal some truth?. Will the m9 take a 3g sim card?..

The sprint phone and any GSM firmware are incompatible due to the different partition layout. The "problem" of this thread lies in the naming of the phone/thread. There are several variants called M9w which all have different MIDs (and slightly different hardware). Just like almost every GSM M9 is called M9u. That's why I prefer identifying them via the MID or their codename. The number part of the MID or the ul/uhl/wl/whl ending of the codename tell you exactly which model is lying in front of you.
Newer CDMA phones (every model that uses LTE) have some GSM frequencies enabled. On the one hand for being able to use LTE and on the other hand since many US customers who traveled to non-CDMA countries prefered GSM carriers in the US, as well, since they could keep their GSM phone whenever they left the US. Many CDMA customers had to buy a GSM phone and a sim card whenever they left the US due to the lack of CDMA on the rest of the world.
As far as I know sprint phones are sim-locked. However, you can contact sprint and request an unlock code so that non-sprint sim cards can be used, as well. Nevertheless, the sprint version doesn't support all GSM frequencies so you might not get any reception if your GSM carrier doesn't use the frequencies that are supported by the phone. That's why it's in almost every case impossible to get LTE with a non-sprint sim card on a sprint M9. (The same apllies to the verizon variant.)
So basically what you're saying is "sell the m9w and buy a wwe"?.

Well, not really. There is no variant that supports every existing frequency. Therefore, the best variant for user 1 isn't necessarily the best variant for user 2, as well.
Scenario a): You live in the US
If you own a sprint sim card the sprint m9 is totally fine. If you own a verizon sim card you should get the verizon variant. If you own a t-mobile US or an AT&T sim card and rely on VoLTE you should get one of their dedicated variants. If you don't care about VoLTE but own a GSM sim card you should get either the unlocked or the dev edition (both are actually the same phone - only the CIDs differ slightly and the dev edition's bootloader is already unlocked).
Scenario b): You live outside the US
If you rely on VoLTE you should get a phone that got branded by your carrier. If you don't care about VoLTE you should get one of the unbranded versions. There is SKU 401 for Europe, SKU 708 and 709 for Asia and SKU 710 for Australia and New Zealand. They're all (the branded and the unbranded versions) the same if you look at the hardware but the firmware is optimized for the dedicated continent/country/carrier.
With S-OFF you can always convert your GSM phone from one version to another. However, the frequencies that are supported by the US GSM variants differ slightly from the ones of the rest of the world.
Tl;dr: You should always choose the variant that suits you best.
Hi,
Does the German HTC One M8 has a Multi-band support for american networks?
thx
For T-Mo and AT&T, yes.
For Sprint and Verizon, no.
How can I find out which Version do I have? (I have bought it on ebay)
install adb & fastboot
reboot to fastboot
type " fastboot getvar all " in cmd
post the result after removing serialno and imei
Checked the mid. Bad luck Verizon :/ thanks anyway
...deleted
Meaning what, the US network you want to use is Verizon?
If so, than you need a Verizon version phone. No way around that, they don't have a GSM based network, its CDMA.
Also, even for AT&T and T-Mob US, a Euro version M8 won't have all the bands needed for LTE. Although, 3G and voice/SMS should work fine.
good
I have the same problem?
siemre I used htc one m8 since 2014 and recently bought another because he had sold it turns out that changing operator in my country, El Salvador.
which it is the company Digicel and using the band 900 Mhz to 4G.
It is to change the m8 and is supposed to be international version but it turns out it's version of att as I can do to release the bands and use it with any operator.
greeting
This is not remotely the same problem. The OP has the German version, want to use it on a US network, possibly a CDMA one (Verizon - although that part is not clear per my comment above).
I'd return the phone, if you can. There is no guarantee you can get LTE 900 MHz running properly on this device. At a minimum, it would cost you $25 US to s-off by sunshine (unless its already s-off), and then you can flash a different radio baseband firmware. Even then, its not a sure thing that it will work on your LTE network. I've seen plenty of cases where phones properly "converted" to the proper band support, still won't work on the desired LTE band.
So the money for s-off may just be wasted (plus the time and effort). Plus, if the phone is not previously modified, you may be voiding whatever return/refund rights you have (if you have any).
