[Q] different hardware versions? - One (M8) Q&A, Help & Troubleshooting

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 love for VZW variants?

I'm not ranting or anything and I understand that Verizon has most of its phones locked down quite well. But with the M8VZW being completely unlocked and rooted, how come there are considerably less devs working with it vs its GSM cousin? Are GSM variants just plain easier to develop for?

Yes.
Also many more GSM users than CDMA users.

what the different between the HTC's

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.

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.

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.

Can I use the H/K Sprint M8 on T-Mobile and get LTE?

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

[Q] HTC One M9 models

Will there be multiple models in the US based on carrier or a single version regardless if you are on ATT/Vzw/Sprint/T-Mo??
Thx

No way to tell for now. Most likely when they become available and they are out in the public can we compare model numbers. Or if HTC details this on sunday.
I would put my money on it being the same as before. GSM variant with only difference being specific frequency bands enabled on carrier models and two separate CDMA models for Sprint/Verizon.
It would be a great idea to have a universal GSM/CDMA model like the iPhone and Nexus 6, but yea i doubt it.
I think Multiple

I think there is going to be multiple models as the US companies take into consideration the user preferences.
The beauty of HTC in Europe - one model for all networks (but different software builds for each carrier)

I hope that's not the case this time. If the unlocked version of the M9 doesn't support T-Mobile (the unlocked M8 was AT&T only) I'm going to pass on this and maybe get a Z3. I don't want a phone loaded down with T-Mobile's crap and have to wait for T-Mobile to push updates out.
It looks like there will be 2 separate versions for AT&T and T-Mobile:
http://www.pcmag.com/article2/0,2817,2477484,00.asp
The AT&T version covers the T-Mobile LTE bands, and will probably be sold as the unlocked version as well. I'm assuming it won't cover T-Mobile's AWS 1700, just like the unlocked M8.

Grr.. Man these carriers are the worst thing. I was hoping the unlocked model will have all the bands but looks like it will just be the AT&T model minus logo and AT&T bloat like last year. Hopefully that's not the case but highly unlikely.

Clarity needed: changing EU phone to NA ROM, does it enable all NA LTE band

I can get my hands on a EU OnePlus 7t or 8 Pro but I want the NA LTE bands for Canada fully functional. I can see that you can switch the ROM, but I just want to confirm if that will allow me to have all the band's listed on their model?
If possible, I'd like to switch and not keep the phone rooted so I can use all apps normally. This possible? Thanks

Afaik the ROM doesn't limit the bands. Imagine buying an unlocked device and travelling abroad. It wouldn't make sense to limit the functionality with software.
However, the hardware as limiting factor is a cost and compatibility choice. Hence, changing the ROM will not make your device compatible to more LTE bands.

Really? I thought there was a software method to enable bands from other regions. Maybe I have my facts wrong though

What someone needs to do is flash an NA (North American) image (for a HD1905 HW variant) to an EU Oneplus 7T (HD1903 HW variant) and actually check whether band 71 works.
And I mean you need to do this with the MSM-tool. You may have to flash the modem partition too I am not entirely certain the MSM-tool does that.
But no-one seems to have done this as far as I know. For the techy users on here this should not be very hard.

It depends if the EU version came with the band in the first place
Firmware does Indeed control the band's. But it is very difficult to manipulate as an end-user.
Phone manufacturers have to go through testing certifications in countries to be allowed to enable certain band's for their product to function there. They keep it well hidden from users like us.
That being said, I don't believe this works with the 7T (or any OnePlus phone).
Most likely chip specific. If the modem chip maker included ALL the bands on one chip, what fun would that be.
By making chips with different bands, they can charge multiple prices, depending on the market, and, phone makers
can sell different phones to different markets instead of a one size fits all approach. $$$$
