No love for VZW variants? - One (M8) Q&A, Help & Troubleshooting

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.

[Q] Galaxy Nexus GSM unlock possible?

Hi! Since quite some time i had been looking for this question on net. Verizon/Sprint Galaxy Nexus version & AT&T/World version phone have identical chipsets. LTE phones have a slot to use sim as LTE is a sim technology based in sim. We all know, that Droid Razr & Bionic are now a worldphone for they have identical chipsets and the NV ram edit can also make it a capable of using it on GSM technology.
Asking Devs if the similar patter can be followed in Galaxy Nexus LTE version and making it capable of using on GSM platform?
I'm sure that can be possible as these CDMA operators block lot of things in a phone.

No, no, no, no, no.
This has been answered already.
The vzw/sprint gnex has no GSM radio.
You need an electrical engineer not a dev to accomplish this task I'm afraid.
Those other phones had both GSM and cdma radios I'm them first day but the carriers restricted them.

Yes they have the same hardware EXCEPT for the radios, cdma vs. GSM.
Not gonna happen.
Just buy a GSM one.
And razr and droid had BOTH radios in them.

Silly Question About Unlocking GSM

Um
I have the vanilla GSM Nexus from Google and currently use it on T-Mobile. Since I cannot find a direct answer to this question, even though I think I know the answer...I want to ask anyway, in case there are others like me.
If I unlock my GSM Nexus, does that mean I can put my Verizon sim card in my phone and have it work or is there a significant hardware difference between the Verizon version and the Google Nexus version?
Thanks -- Be gentle with your replies.

No you cannot. The main reason is the fact that GSM version only has radio that is capable of GSM and HSPA+. Verizon radio is capable of CDMA and LTE. Whatever you do to the software, if the hardware isn't right, there's no way.
Also may I ask you what you mean by unlocking? Do you mean unlocking the bootloader? If so, that has nothing to do the radio.
Hope that answers your question

I just want to make sure I am not crazy in how I interpret some of the posts I have read.
I am perfectly happy sticking with T-Mobile. I will just let my Verizon contract run out, then they can suck it.

The GSM Galaxy Nexus is SIM unlocked out of the box. It will work on any GSM network, but no, it will not work on Verizon because they are CDMA and LTE.
Remember that when people talk about "unlocking" here, they're usually referring to the bootloader, not the SIM card. Unlocking the bootloader has nothing to do with the network it runs on, but instead has to do with putting ROMs on your device.

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.

This seems to be the root for S8+

Has anyone here tried the new root file for Verizon S8+
https://download.chainfire.eu/1080/...to-Root-dream2qltesq-dream2qltesq-smg955u.zip
It will only work with an unlocked bootloader. Since all US Snapdragon based S8's have a locked bootloader it useless.
So why has Chainfire made this at all if it does not work or will brick your phone? I should ask him but not sure he will answer.

He clearly states that it only works with an unlocked bootloader. If the snapdragon versions of the S8/S8+ had an unlocked bootloader it would work. Not sure why you could have an issue with him.

The U version isn't ever unlocked. Not with him. I'm just confused why it seems this would work on that model but it doesn't
If the bootloader ever gets unlocked by any means, it will work.

You missed my point and question to him. Which is "U" model is LOCKED because it is all phones inside the USA that are distributed by all 4 major carriers. So there is no such thing as SM-G955U which is unlocked. Does not exist. Thus I wanna know why there is even a zip file which chainfire created since it cannot be used on any of these phones. And why would it "get unlocked"....it is done at the factory. Only way to "unlock" it is to use a root method like was done on S7, where it basically involves flashing an engineering boot image/kernel that has root. At some point, this probably will be made and then using same modified ODIN (PrinceComsy) would potentially be the solution.

I will try and clear up some confusion. All US snapdragon versions of the S8+ have the same model number SM-G955U. There is an "unlocked" SM-G955U version of the S8+ in the US. It is carrier unlocked not bootloader unlocked. Apparently the CSC file carries the carrier information in the firmware. Also the S7 was rooted but never bootloader unlocked. So you could use most root apps but you could not modify any system files. The root was achieved with an engineering kernel and was not very useful.(ie bad battery life, phone getting hot and unstable). You could however flash any US S7 to any carrier or even the Unlocked firmware.
But if you cannot flash even the csc, how do you gain root access when Odin basically does nothing. That's my question and point. Seems that if I stick with Galaxy phones that I'm never going to attain root again. Probably because they don't want risks of pay apps being misused. I have one app that refuses to even run if I have usb debugging on. Vendors are getting smarter about locking things down.
It's not Samsung's fault...it is Verizon, AT&T, Sprint and T-Mobile. I can't even take my Verizon phone and change it to T-Mobile. That's ridiculous!
If LG lets it's consumers unlock there bootloader then why don't samsung? I'm selling my ccarrier unlocked s8+ and buying a unlocked g6. Screw this crap. I hope samsung goes bankrupt! SAMSUNG ALLOW US TO UNLOCK OUR BOOTLOADERS.
I wish my S8+ was rooted?

The reason you can't do this is the bands are different (I believe). Or, at least Verizon is CDMA while T-Mobile is GSM. I don't know much about the differences between CDMA & GSM, but I know that CDMA phones won't work on GSM networks & vice versa. That's why Verizon phones won't work on T-Mobile. Hopefully that (kinda) cleared it up for you.

My goodness you could not be any more wrong..... That is no longer the case anymore. Verizon phones work on T-Mobile and all GSM carriers. I should know since I was with Verizon and I switched a while back but am now back on Verizon. Some phones from T-mobile won't work with Verizon but some do. It just depends on the phone and what bands it has. Like the S8 from T-Mobile will work on Verizon but an iPhone 7 from T-Mobile won't because it doesn't have CDMA bands. It's simple research

CDMA is only for 3G. With 4G, Verizon is using LTE GSM (same with AT&T, T-Mobile).
Verizon LTE covers over 98% of their network, but there are still some remote places where there is only CDMA coverage.
Verizon is moving away from CDMA and it will be retired by 2018.
So as long as you don't mind not having CDMA in a few places, any LTE GSM phone with Band 13 would work with Verizon.
Look at HTC U11, it doesn't have CDMA, but it's still advertised as "Verizon certified".
Sadly, the Internationals versions of S8/S8+ don't have band 13. But fortunately, all US versions have both bands 13 and CDMA support. That's why you can switch to any carrier as long as it's a US version.

My point exactly about the S8's. US variants are all the same no matter what carrier. All Google phones after the Nexus 6 are the same way. The Nexus 6 worked on all US carriers no matter where you got it from and it's like that all the way to the new Pixel phones. Where as iPhone's, just as an example, have different bands when it comes to different carriers. Unlocked, Verizon, and Sprint iPhone's have all bands both CDMA and GSM where as the GSM ones like those bought straight from T-Mobile or AT&T only have the GSM bands.

You're NOT stupid! I had no idea either. I know that I tried to switch my Verizon S8+ to T-Mobile but it wouldn't recognize my IMEI so I just figured the two networks were different
I have a unlocked verizon(xfinity mobile) s8plus on tmobile right now.. The phone had no issues on setup to go on the tmobile network..
