hii guys ,,
im going to buy the HTC m8 next week
i'v seen many type of version of the phone
like AT&A , Verizone , Sprint , Google Edition
so anyone can tell whats the different between them if there any !!
thank you
I believe the hardware is the same on all M8 variants (apart from the dual SIM ones) so all the differences lie in the software side.
AT&T, Verizon and Sprint will have a few differences to each other due to the bloatware they decide to add in.
The Google Play Edition (GPE) is running vanilla android rather than Sense (the same as Nexus devices). As they're Google devices, they'll get updates quicker than the other M8 variants (just slower than Nexus).
There's the developer edition which runs Sense but comes with an unlocked bootloader and will get updates quicker than the other Sense M8's, but not as quick as the GPE.
Then finally there's the Windows M8. This is simply running Windows 8.1 (I think) instead of Android.
It would help to know what region you are located in.
Some of the US carriers (Verizon, AT&T) have their logo on the phone, so you might not like that. And there is some difference in the colors available (for instance Verizon has red, Sprint Harmon Kardon edition has black back and sides with gold front). Other than those minor cosmetic differences, the hardware is identical, from what I understand.
Band compatibility is different on each carrier version, but is software based and can be changed by installing the proper radio (S-off required, which will probably also require sunshine s-off, which costs $25 US).
And as mentioned, the only other difference is the stock ROM, which for US carriers will have their own carrier branding and (tons of ) bloatware. Again, easily changed with unlocked bootloader or S-off.

Software wise theres carrier bloatware on each device. But hardware wise the Verizon / Sprint ones have an added CDMA chipset and from what ive read they are different from the GSM units hardware wise.
Blowing a GSM rom into a CDMA unit will brick it, or so ive read.

I thought and had heard the same as well (hardware difference between CDMA and GSM M8's). But several folks here have strongly claimed otherwise, that the radio difference is still in software; and that all M8's are the same hardware-wise aside from the dual SIM M8. So I'm not really sure what to believe.
That being said, the OP should probably get the version offered by their carrier, or intended for their region. Even if it can be "converted" by software, it just makes for less steps and less hassle. Unless there is some strong reason to do otherwise, like a much lower price.

I'm not too sure about this either. I've seen a lot of people saying they have the same hardware and seen a lot of people saying CDMA have different hardware.

And I haven't actually seen any definitive evidence for either case.
Looking at specs, both (GSM and CDMA versions) use the same chipset (Qualcomm MSM8974AB). I would think if there was a difference due to CDMA, it would have a different chipset number. But that's just a guess.
OP should stick to the version that matches their carrier (GSM versus CDMA) to be safe.

I actually thought the most "obvious" difference in hardware was the actual circuitry itself. They use similar components etc but the way it's "wired" is a bit different, but I don't recall where I got that info from

It would be great if you could link the source, it would settle this debate.
So you mean the copper trace/tracks between components on the board are different? I would assume that some of components and/or the layout is also different, otherwise why have different trace paths?
The following teardown shows the layouts of the Verizon PCBs, but I can't find similar into for the GSM version to compare it to:

Anandtech actually has a great write-up on the differences between the various models.
http://www.anandtech.com/show/7893/the-htc-one-m8-review
Specifically, the chart on the supported bands is useful.
Thanks for the help guys
I think all the versions supported here with operator, im located on Israel for now
If there is no hardware different is it possible to flash a firmware from Google edition HTC to another versions?
So I dont have to wait too long for updates
Thanks again

The main difference in GSM version is the frequency/band it uses for 3G/LTE.
Everything about the GSM version is the same except for each have different frequencies enabled.
So find out in Israel what cellular company you will be using and what frequencies their 3G and what LTE band if any. Then you'll be able to pick which m8 is right for you.

what ever model its a amazing phone .
It is amazing indeed
It seem im getting the Gunmetal version
Any ideas about it!?
When an update roll out for HTC Google edtion is it possible to flash it on my phone after unlocking bootloader?
Thanks

Gunmetal finish is available for a great many versions/regions, so telling us that alone doesn't say much.
But GPE full conversion is possible with unlocked bootloader and I think S-off also.

it's probably a nub question, but i can't find the answer
do all the M8 variants (AT&T,VERIZON,T-MOBILE,GOOGLE) have the same hardware (except the Asian one)
if so, does it really matter who i buy from?, because ones i unlock it (sim-lock) i can install any ROM/kernel and use it in any network.
is this the case?
Thanks!
There are different bands supported on the different variants. Look to GSM Arena to see the differences. Otherwise I'm pretty sure all variants are the same.

Just to let you know that you are not 100% sure that you can unlock it. Some devices cannot be S-OFF-ed for the moment.
bands are not software dependent ?

No, they are hardware-dependent
Is there a patch to make my vzw M8 work like it was a native Tmo M8?
No. Hardware is different.
Verizon has CDMA chipset and the TMO verison is a GSM chipset.

That's not true...
My phone is Fully unlocked and gets everything from Edge to Legit LTE.
My phone works. I just need it to work a bit better.
And the reason you want it to work better is because its not the correct version for the carrier you want it to work on.
http://www.gsmarena.com/compare.php3?idPhone1=6233&idPhone2=6074
The bands are almost identical with the Verizon unit missing 1700mhz on the HSDPA side.
Either way if you want it to work like its supposed to get the branded one. Unlocking will work but in most cases something is always missing.
could be specific software, or the way the device works with the network, or an entire band or what ever.
Bottom line is ditch the unlocked verizon and go with a branded tmobile unit.

Since you seem to already know the answer then go ahead and flash a tmobile or any other gsm rom to your phone and see how fast you brick it.

What a bummer.
Using CyanogenMod M9 with Verizon M8 on Tmobile
I have found that this works pretty well for me. CyanogenMod 11 M9 (I cant link to it, forum wont allow me to)
I have not had any issues with that build using a Verizon M8 on the Tmobile network.
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 just got my T-Mobile variant m8 and had been sticking to the rather limited rom selection in my variants forum, but I discovered the general HTC One_m8 forum had tons of roms that supported GSM and CDMA phones. I'm feeling a bit confused, since any phone I've had previously never had been on multiple carriers. If a rom in the general android development section says it supports gsm variants ( using my brain when selecting, of course), will I be able to just change APNs to make it work with my network?
Apologies for noobiness, I'm just finding the world of roms again after my last phone had none.

Its not a stupid question, by any means. And the answer is not simple either.
Any ROM intended for GSM versions of the M8 should be safe to flash, and will for the most part work (and if fact may work perfectly). The hardware for all GSM versions is essentially identical aside from cosmetic differences.
However, some folks have gotten slower data speeds on ROMs not intended for their carrier. In particular, I've seen this mentioned by some folks using "international" based ROMs on the AT&T version. Your mileage may vary, and it might not be an issue for you. I don't want to discourage you from using any particular ROMs; but just want you to be aware.
Flashing the most recent radio for your carrier may or may not help, and is probably the smart move. s-off required to flash a radio manually, alternately can be installed by official OTA or RUU, and your phone may already be up to date.
In any case, stay away from ROMs intended for the CDMA versions of the M8 (Verizon, Sprint) as the hardware is actually different, and I've seen folks brick from accidentally flashing things meant for the wrong hardware version M8 (CDMA vs. GSM).

Are those 2 things mutually exclusive?
Yes, that was me. I was on that forum a lot and maintained the Index thread.
Looked around and not sure if this is even possible. Could I get a H/K M8, unlock it and use on T-Mobile's network to receive LTE? Thanks!
Is there a reason why you are looking at the Sprint version?
Its been argued whether the CDMA versions of the M8 are any different in hardware, but I haven't seen anything definitive either way. I'd err on the side of caution, assume the CDMA version is different hardware, and stay away from it. Buy any GSM version and you can convert it to work on T-Mobile (after s-off, unlocking the bootloader, etc.), no question there.

The only reason I'm looking for the Sprint version is because of the look. I like the dark back metal and gold upfront a lot. Sucks its an exclusive look only to Sprint. I read that you can flash the other non H/K models to have the same software so that is confirmed and all good.
Now I need to find someone who is using this Sprint model and can confirm it has the needed GSM radio(s) for TMO LTE.

I'm pretty sure that Sprint models are CDMA only. You can't use their phones on GSM networks. I don't think what you are trying to do will work. I may be wrong here, but I really doubt I am.

This is incorrect (that the Sprint variant does not work on GSM). Both the Verizon and Sprint variants support GSM and CDMA. Folk on here (including myself) tend to refer to them as "CDMA" for simplicity; but they are in fact also compatible with GSM, as well as HSPA, LTE.
http://www.gsmarena.com/htc_one_(m8)_cdma-6233.php
Now the question is whether the difference between the GSM and "CDMA" variants are purely in software, or there is an actual hardware difference. Its been argued both way, and I haven't seen any proof either way (although my gut tells me the latter is the case). And the question relevant to the OP is whether the T-Mobile LTE bands can be "added" to the Sprint device by software.
I used a verizon LG g2 on T-mobile a few and the phone im writing on now is a verizon iPhone full lte but i dont know aboit the sprint versions
