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.
Aside from the CDMA RUUs, which I wouldn't try on a GSM version unless you read definitive advice elsewhere that its ok.

Only US versions have RUU, that I know of.

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?

WWE just means "world wide English". I think it refers to the Euro version.

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.

I have a question. Does T-Mo work with WWE firmware. I'm unsure of this, and have never looked it up. I know that AT&T versions are compatible with 401 firmware. Is T-Mo the same?

but you could check with the seller if it is S-OFF already (as you can be S-OFF with 3.19 if it was already done) if thats what you are going to do anyway.

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.

DEV vs WWE

Hi, I have a question.
I have my AT&T phone converted to developer version with 6.12.1540.4 installed.
Everything is good, but I've noticed that WWE update 6.12.401.4_R came with R letter. After some googling I've figured out that R means Rebuild in this case.
So, technically WWE version would work better? Should I convert my phone back to WWE?
Also, in general, what would you suggest to use in US with often travels to Ukraine?

I want to know this as well... Is there any software updates between the WWE and dev edition.
If there isn't then I don't see the point to update but need a concrete answer :/.
I am aware that between .401.4 and _R the only difference was the boot image.

Rebuild or newer, doesn't always mean better.
Both having the same build numbers 6.12 means they are very similar. So I would say no need to change.
From what I understand, 6.20.401 is coming (with some significant updates), not sure if a 1540 build (DevEd) will be coming or not. But that might be more of a reason to change.

Different emoji, and a security patch.
Actually, finding the post, its 6.20.709 for CID HTC__621:
http://forum.xda-developers.com/showpost.php?p=65028941&postcount=3
But if that version is getting updated, I would guess WWE will, as well.

The only real difference would be the network band support. So what version is best for US, depends on which carrier you are using (or intend to use); as there are 4 major (and numerous small regional) carriers in the US, which all use slightly different bands for 3G, 4G.
As to what version is best for Ukraine, you will need to find what band your intended carrier uses for 3G and 4G; and what version's radio supports those bands.

Flashing generic Samsung firmware to carrier branded Tab S4 (SM-T837T -> SM-T835)

I think this has been asked before in a different way in this section but no real response yet. I did some research in the other Samsung device forums and see that often it is possible to remove branding or switch carriers adjusting device ID and bootloader etc. But no idea how to do it for the Tab S4.
I'm sick of waiting for slow updates through T-Mobile (or any carrier) and would like to fully unlock it's potential with Android 10 rather sooner than later. I bought this device second hand network unlocked.
Any short or long answer to these questions? Can it be done? If so where to start?

Am looking to do so, with the t835 you will have full calling functionality,,,

not needing the calling function on a tablet. but steady updates are welcome... tired of waiting twice.. first for Samsung with slow update policies then another time for carriers that already got their money and cant care much a anymore...
i'd be looking for T835C since I'm in China now.

The short answer is no.
I've tried that after I found my T837V can be successfully loaded with T837R4/T837T/... firmware. I thought maybe I could flash stock firmware of other versions. But if you do that with any firmware other than T837*, you will get "secure check fail pit" error. So sadly no.

Thanks for the response! So it does mean you can freely flash T837 versions which could mean I can just wait for the first version that comes out with android 10. Any first release should work. Right?
Turkey version has it:

T837 is Turkey version and I've tried it. It can't be loaded, maybe it need to be T837x which are all US variants.
As for Android 10 update, I think this will work. I'm waiting for the first one who gives the OneUI 2.1 update. So far the Verizon version(T837V) seems to have the most active firmware updates.

In the USA, SM-T837 ARE carrier tablets.
There are the SM-T837A, V, and T; ATT, Verizon, T-Mobile. TheSe are locked to the Carrier. If you have them unlock it, OTA upgrades are over. If you know how to hack the firmware, you can write over the carrier version. The best way to go is probably custom ROM AND ROOTING. But in other nations, it will probably work to write a different Samsung ROM. The SM-T835 HAS no US version, so you can probably write any tab s4 Factory ROM to it.
The USA HAS so many cellular devices, the rules are strict. And, the carriers sell the devices pretty cheap. So, they want them to stay with their service.

T-mobile update for android 10 finally out just got it

Every carrier? What? I know of 3 versions of a11 for the G8; 1) the korean Open 2) The Verizon version 3) The Canadian Open.
Hardly 'every carrier'. Updates are coming, slowly, and there is no guarantee any one individual carrier will update their software. That's an LG issue really, they have contracts with carriers with various stipulations that can affect say US Open version, which supposedly can't be updated unless all the other carriers update theirs first. It's complicated.
Call t-mobile, they can tell you when / if an update will be available. And of course, there's always the issue of what you've done to your phone. If you do something like unlock the bootloader, you won't get an update even if there is one.
cheers

Actually, that's not the US Open variant, that's the CCA variant. I'm not sure what the difference is, maybe someone can elaborate.
The lg firmware site has it listed as the US Open, but download and compare the hash tags, they don't match. But if you download the CCA version the hash will match.
I've actually never heard of CCA before, it's Competitive Carriers Association, I've heard of BrightPoint, etc, but not cca. Until someone tries it, we're not sure which carriers it's compatible with re volte and vowifi type stuff.

My phone is originally BrightPoint. I flashed the US OPEN listed on the lg firmware site, hoping that it wouldn't throw up an NT ID error, but it does :-(
Additionally VoWiFi worked with the Canadian Open but it's not working with this rom. The default email app is also missing in the US version.
The software version shows as V30c-USA-XX, with a security patch of Dec '21.

Interesting that it's not working vowifi and nt error code, that should absolutely not be the case if it was the USA version, no way. At least not if you're here in the states.
Where are u using it? Canada? That might be at least part of the reason, have you ever used the a10 US Open there? How did that work?

Sorry for not clarifying earlier, I'm using the phone in India
To get volte and vowifi to work, I change the target region & country to ESA and operator to OPEN in cust.prop. And i also edit the carrier_code, telephony and vo_config files to contain details of the networks in India.
VoLTE has worked with many A10 roms, but VoWiFi worked for the first time with the A11 Canadian Open.
PS - Since I need an unrooted phone for Microsoft apps such as Outlook and Teams, I uninstall magisk after making these configuration changes.
