Will this work? Verizon M8 --> AT&T fo-'official'? - AT&T HTC One (M8)

I have an old M8 lying around that I fired up and had remembered I had rooted it and the bootloader is unlocked.. Is there a way to 'trick' this phone into thinking it's an AT&T branded phone? hboot, etc. and that will allow me to RUU something official from AT&T? I know this sounds really strange and probably stupid but.. I just can't sleep and need something to fill the time.. Can I do it?

Don't think so, radio hardware is different, not to mention the partition layout.

Absolutely not. At least not any way that is known; and your chance of failure is high (with a brick being the possible or even probable result).
As mentioned in the previous comment, the partitioning on the phones is different. If you try to run the RUU, you at best it will fail, at worst it will brick the device.
Most other M8 versions (that don't support CDMA) can be "converted" from one version to another (other exceptions being dual SIM and M8 Eye). But Verizon and Sprint are the oddballs here. Some experienced devs have been messing around with these variants from the start (to try to convert them) with no success.

Perfect! All I needed to hear! Ah well.. it was worth a shot! Just trying to get my account provisioned for LTE so I can get LTE on my unlocked devices.. I've been told, and read, that if I can get an AT&T branded LTE capable phone to just swap my SIM in it.. and let my account provision, then I'll have LTE on any device AT&T or not... Just trying to avoid a contract..

As long as the phone is SIM unlocked (Verizon version is) then you should just be able to put an AT&T SIM in, and enter the proper AT&T APN for service, as long as the phone supports the proper bands. Its irrelevant whether the phone is AT&T branded or not.
Now the underlined bit in the paragraph above is the main issue. The Verizon M8 only supports one of the four bands (Bands 2, 5, 4, and 17) used by AT&T for LTE (Verizon M8 supports Bands 3, 4, 7, and 13). So depending on what band is used in your area, you may or may not get LTE.
But GSM (2G) and HSPA (3G) should work just fine on AT&T.

That's the odd part.. My main phone is the S6 Edge from Verizon.. it's on the AT&T network and I assume my APN is correct.. But it's not picking up LTE and I am almost certain the S6 Edge from Verizon will pick up the correct band for AT&T LTE .. But it's only using the H+ speed.. What's even more strange?? When I throw my SIM into the M8? I get LTE on AT&T and verify with 30+mpbs speeds.. I have no idea what's going on...

Yeah, that is strange. According to the specs for the S6 Edge here, the Verizon version supports the same LTE bands as the VZN M8, and actually some additional bands (2 and 5) that also happen to be bands used by AT&T.
One thing I can think of, is that the VZN M8 in actuality supports some bands that are not advertised/explicit in the specs. It wouldn't be unheard of, as members here have reported some versions of the non-CDMA M8 as supporting some bands not indicated in the specs. And that band happens to be what AT&T is using in your market region. In this case, that band would seem to be Band 17 (the only band that AT&T is known to use, that isn't listed on the S6 Edge specs).
Or the other possibility, is there is just some issue with the S6 that is preventing connection to LTE (but on the same supported band that the M8 has).

Yeah.. I'm not worried about it.. I've been told that all I need is an AT&T branded LTE capable device hooked up to the account and that my account hasn't been provisioned for LTE .. I've seen this in a few places so it's worth a shot.. I ordered a junk LTE phone branded AT&T to test it out.. ordered a OnePlus 2 and will likely unload the S6 Edge (if it never picks up the LTE from AT&T)

As I've already mentioned, its not really necessary to have an AT&T branded device. I suspect the reason you've seen people say this, is that AT&T branding means by definition the phone has all the bands used by AT&T for LTE; since obviously the phone is intended for use on AT&T's network. Since AT&T uses a number of bands (4) and LTE bands being used worldwide has become very un-standardized, its somewhat difficult to find a non-AT&T phone that has all the bands. But they do exist, such as the US unlocked M8, Dev Edition M8, and Nexus devices. Also, I've seen folks used other non-ATT branded phones, which may not have all 4 LTE bands used by AT&T, but the one(s) needed in the particular user's region. Not ideal, but sufficient for some folks.
Another reason why some may say the phone needs to be AT&T branded, is that AT&T tech support won't provide you any support if you have a non-ATT phone. But honestly, I've used non-branded devices (and plenty of folks here have), and this is very rarely an issue. The folks here on XDA will usually provide you better support, anyway!
Of course, your ATT account needs to be provisioned for LTE in order to have that service. Its a simple matter, and doesn't cost anything (just need a smartphone data plan).

I've dug deeper and have to not only have an AT&T branded phone, I have to register the IEMI on my account, then swap the SIM card back into the other phone. I've got the phone but can't find a way to do this online so I'll have to call tomorrow...

Absolutely NO.
What I mentioned above (Post #3) for the Verizon variant, also applies to Sprint (both versions support CDMA - the fact you don't use it is irrelevant). If you try to convert to another version won't work, and will probably result in a brick.
Also, even if you didn't have a CDMA version M8, you typically can't convert using an OTA, it has to be an RUU.

Absolutely NOT. As already thoroughly discussed on this thread, if you attempt to install another version's radio on the Verizon version, it won't work, and you may radio brick the phone (permanent damage possible).
Different radios, different partition layout.
Don't even try it. Experienced devs have tried to "convert" by various methods and mods, and failed.
But there may be other ways (besides flashing another version's radio) to enable the band(s) you want, read on:

UK/EU release this year?

I see this phone isn't getting released in the UK/EU first, which is..... different!
I would like to know if there are plans to release this device or a similar HTC device anytime this year in the UK/EU region.
I hope HTC it will be available for sale before the beginning of December
I would rather have had the Droid DNA/J Butterfly instead of the One X+ in the UK.
You would think that with HTC's recent financial results, that they would be looking to release this highly anticipated device in many markets as possible.
Does anyone know if the Droid DNA will work on GSM 3G HSPA networks? Obviously the LTE wont work.
I wonder if any of the Frequencies Vodafone or O2 are going to use are the same as the US ones? I do remember reading it somewhere, and I don't think they are the same.

The problem is not the LTE, it is the basic network of the phone. The Verizon network is not compatible with any European network - they use a completely different system as the base which is not GSM compatible. Same reason the Nexus 4 "world" phone works pretty much everywhere except on their network.
Until HTC make a model with different radio chips (GSM standard) this phone will only be for Verizon and a couple of Japanese networks.

From Verizon's DNA specs list:
CDMA1x/EV-DO Rev A, LTE/DO Rx diversity
Global Network: GSM (850MHz, 900MHz, 1800MHz, 1900MHz), UMTS (850MHz, 900MHz, 1900MHz, 2100MHz)
Since it has GSM, will it be possible to use in Europe or Australia?

Yes.. It's just a matter of whether or not it is unlocked out of the box like the Rezound was (Limited at first before update). Or sim locked like previous droids.

Thank you for posting this... I hate when people (read: nexus161) give outdated facts based on the way the tech ran several years ago... vzw has released several devices with a quad band antenna in the past several years. The gsm bands listed are frequencies that all gsm providers currently use at least one of so the answer to the original question is yes, in theory. I'm assuming the international bands are unlocked so there should be no issue using it with a gsm provider, however I'm not sure how vzw has played this in the past so I can't speak to how this will work in practice. My guess though? Similar to the rezound. Locked for first 6-8 months, then an unlock will roll out in an update later.
That's great, so it will work over here. I'm not bothered about 4G yet as its only in a few cities.
I'm new to this whole Verizon CDMA unlocked thing. Can I use a US T-mobile SIM card and pop it into the SIM slot and it will work? What size SIM does it use? Micro?
Do you think it will be possible to buy a Us handset and unlock it?
Will it be 4G enabled?
I just spoke with three different verizon customer service representatives and they all said the phone is locked to Verizon. Two of them said Verizon never unlocks their phones and the last one said devices can be unlocked if you have 90 days of good payment history. Is there a different way to unlock android devices other than having carriers do it for you?

Sometimes... I think you need to have S-Off though... I could be wrong though.
Just because it has GSM support in the radio, doesn't necessarily mean it has a SIM slot! If I'm not mistaken, the Photon Q or whatever the Moto slider for Sprint is has a pentaband radio but no SIM slot...
Anyone got details on that?
That phone have sim slot

Verizon Samsung Galaxy S4 to have AWS 4 Band (Tmobile LTE Capable?)

Hi,
So I've read the FCC documents located here: LINK
Page 1 and Page 5 are the most interesting! These state that the Verizon model SCH-i545 will have AWS band 4 (of course 13 too) which does support T-mobiles LTE network right? It never states 1700/1200 frequencies.
Thing I want to know from the pros is will this phone indeed offer LTE support for T-Mobile or and I'm just seeing things?
Also, for all the other people that are wondering if the ATT model will offer LTE support for T-Mobile as well? It will since it supports both bands 4 and 17 But wait is that AWS band 4?... the jury is out on that! -_-
Many Thanks

If I am correct, Verizon phones do not use sim cards (CDMA) and AT&T and T-Mobile are GMS (sim phones). So even if the bands are supported, I don't see how a Verizon phone would work on T-Mobile or AT&T unless they are CDMA / GSM dual phones. And even then they would have to be unlocked.

All of the major Verizon releases over the past year have come GSM unlocked. They are world phones that contain GSM and CDMA radios. I'm using a Verizon iPhone 5 on the Straight Talk (AT&T) network currently.
All lte phones have sim cards as it is a gsm technology. My girls verizon gs3 has a sim. As far as it being compatible that is a hell of a question.

Hey this is one question i have lingering on my mind. How is the StraightTalk connection? Is it any good? Are there call drop issues? And do they have data plans?
if i buy a tmobile s4 will it work on verizon??
I know most things are under the catagory of speculation/rumor but i was wanting to to check out tmobile network for a bit.... the no contract is appealing. If i bought the phone outright and ending up not liking tmobile i would switch to verizon. Short of selling the tmobile and getting a verizon phone i was wondering about just activating the same phone on verizon?
Will there be "one phone" in US or would they all have thier own modem chips i guess is the real question....
thanks for the guesses and speculat'n!
You have to consider its Verizon and they have 700Mhz LTE and you can't roam on AT&T's 700Mhz so I would not expect to access Verizons AWS spectrum on T-Mobile or vice versa. Remember when they said LTE was the unifying spectrum to allow for easier use across networks and carriers, well that was a pile of BS.
Great news, but I heard verizon was purposely going to burn in their logo onto the amoled screens.

Wrong: those "700mhz" frequencies are different bands. Both T-Mobile and Verizon are building out LTE on the same band: 4 (AWS). They will be interoperable device-wise.
AT&T also owns a lot of AWS, and though they're currently running LTE on it only in one market (somewhere in Oklahoma IIRC), all their LTE devices do come with band 4 enabled.
The more I read about the differences, the more I'm convinced that the Verizon model is more cross compatible with all other services. It's still the only CDMA model. But it's also gsm unlocked if you know how to program APNs. Any thoughts?

if we ever get to the point where we don't need 3g at all any more (CDMA) and we can get VoLTE and use the LTE band exclusively that will eliminate a lot of the incompatability between Verizon and GSM carriers .

When we get to that point, Verizon will basically be a GSM carrier. Considering LTE is just an evolution GSM, both developed by 3GPP.

[Q] Unlocked HTC One M8 (M8_UL) no 4G LTE only HSPA 4G

I need some assistance from the Pros on this one.
Problem: phone only connects to 4G HSPA, will not connect to 4G LTE no matter what I've tried. AT&T tier 3 technical support said by all means the phone should be connecting to 4G LTE. Unless the phone was falsely advertised as having support for 4G LTE.
This is the phone I bought for my wife: http://www.newegg.com/Product/Product.aspx?Item=9SIA2NR2977129
It advertises 4G LTE Support 700/900/1800/2100/2600 MHz
Also supports: GSM/GPRS/EDGE: 850/900/1800/1900 MHz and UMTS/HSPA: 850/900/1900/2100 MHz with HSPA+ up to 42 Mbps
The IMEI number shows in the IMEI database as supporting 4G LTE and all associated bands.
Phone Info:
HTC One M8 (International Version)
Model: M8_UL (the AT&T version is M8_UL_CA)

What else can I try to enable 4G LTE? I already took the SIM out of my phone and put it in my wife's phone. Still her phone will not connect to LTE.
Are you checking the status in settings>about>network or going by the icons in the status bar? I'm using a "multi-carrier" ROM and the status bar icons show 4G for LTE and H for HSPA. I believe the ROMs built on ATT base will show 4GLTE and 4G, respectively.
Dial *#*#4636#*#* and Confirm Network Type

You can't really rely on the icon, it's best to check the connected band by using this method:
Tap Phone
Dial *#*#4636#*#*
Tap Phone Information
You can change your radio frequency to USA or International
Select the Bands you want your phone to support
View Network Type: LTE, HSPA etc (it should always read LTE if you have an LTE plan and your near an LTE capable tower. My phone reads LTE always, my wife's reads HSPA)
Run Diagnostics etc.

Right. That was my point. Just making sure you weren't being duped by the status bar icons, as they are different for ATT and other carriers.
You might want to try running a full RUU for ATT to see if it will connect to LTE. That way you will be sure that all firmware, radio, system match for ATT.

You're on the right track! That was the first thing I did, I installed this ROM 4.28.502.1 from here: http://dl3.htc.com/application/RUU_...40.45.C33065.00_F_release_426617_signed_2.exe
Latest official AT&T, still no LTE, HSPA only. Sad Face.

Ah bummer. What phone are you using? Does her sim card connect to lte on yours? I have read some posts where a new sim card from ATT store fixed this issue, but I know you tried yours already. Maybe hardware problem with the phone itself? I'm out of ideas, sorry.

I put my SIM in her phone and visa versa, and both SIMs get LTE on my phone, but not on her phone. Here's what I think. The seller on Newegg changed the IMEI and falsely represented the phone as supporting LTE. That's really the only think I can conclude. The IMEI number it shipped with states LTE support in the IMEI look-up database. OR the IMEI information in the database is inaccurate for the phone.
The hardware is identical to the AT&T version, as are all "GSM" M8 versions (meaning Verizon and Sprint are excluded). So there shouldn't be any reason why LTE shouldn't work, as long as you are on the correct radio.
Its not a hardware issue, and something else is going on. It seems from your OP and subsequent posts, that you've tried a variety of things. You radio and ROM are kind of a mish-mosh right now. I'd suggest RUU back to stock Dev Edition or stock AT&T (latter probably being the best bet) and let us proceed from there to make things less confusing.

I flashed the latest official AT&T ROM, but this made no difference what-so-ever. I'm currently using the exact same ROM and firmware on my HTC One M8. I get LTE all-day-long no problem, my wife's phone does not. I already changed the MID to match my AT&T MID and also the CID, but that made no difference. The only thing I haven't tried is changing the model name. My model name is M8_UL_CA and hers is M8_UL. I can't figure out how to change this value, but I'm not sure it makes any difference.
AT&T LTE bands
Band2 1900MHz
Band4 1700MHz
Band5 850MHz
Band17 700MHz
Band 17 is AT&T's primary LTE band.
Phone is advertised as supporting the following LTE Bands
LTE: 700/900/1800/2100/2600 MHz

Just the ROM, or the whole RUU? There is a huge difference. There are something like 36 partitions, and ROM (/system) is just one of them. The RUU flashes every partition.
I know you mentioned you previously flashed the AT&T RUU. But its also clear that you did a bunch of other things since then. The reason (as already stated) I want you to RUU now, is to put you on a stock AT&T software to give us a clean "blank slate" to work forward from here. As opposed to having too many other variables that can cause problems. For instance, its a known issue that Euro ROMs (such as ARHD) have some issues on AT&T's LTE network. So being on that ROM just compounds another layer of issues on top of issues. Going to a stock AT&T software configuration is a much cleaner state to troubleshoot your from.

Model name does not make any difference, that I have seen. I've seen plenty of folks "convert" from one carrier version to another, and the steps of s-off, change CID and MID, flash RUU is all it takes (changing model name not required).
And that is probably also the reason that I've never seen a mod for changing model name (it doesn't actually affect anything as far as device checks).
I'd say, don't worry about it and don't waste your time trying.

By "primary" band, I assume you mean the one most commonly used by AT&T. Your phone needs to support the band that AT&T is using in your area. So unless you know for fact that 700 Mhz is what they are using in your area, it can be any of the four bands.
I mentioned that that this is not a hardware issue. But I should clarify, its not a matter of a difference in hardware between GSM versions (since they are actually all the same). But it occurs to me that it is fully possible that there may simply be a hardware defect that means your LTE simply broken, and the seller should replace the device.
If we can successfully confirm that you are on full stock AT&T software by RUU (confirm proper radio, main version, etc.) and LTE is still not working (and we know the SIM is good); then I pretty much have to conclude the phone is simply defective/broken.

I installed the HTC One M8 AT&T full RUU from this webpage: http://www.htc.com/us/support/rom-downloads.html (made no difference) and I tried it twice just to be sure so... it must be that AT&T in my area is using an unsupported LTE band, OR like you said something's wrong with the radio. Doesn't the radio hardware have specific frequency crystals to send/receive only on certain frequencies? Or is this is a fully digital self-tuning radio that receives/transmits on any frequency as programmed.

I've never heard of AT&T using a band not supported by this phone. Their LTE network is fairly mature at this point, at least to the degree that they aren't adding bands not previously used, and not supported by relatively current (AT&T branded) devices.
If you confirmed that the proper AT&T radio was properly installed by the RUU, and checked the APN is good; have to conclude there is a hardware defect.
Normally, I'd suggest in that case that you contact the seller for an exchange or refund. But this is a tricky situatin, in that you've modified the phone, and trying to get it to work on LTE bands not specified for the device as it was manufactured.

Nope. Not sure about "crystals". But while you are correct that in older phones the band compatibility was set in hardware; the Snapdragon 801 was one of the first smartphone chipsets (if not the first) where band compatibility is determined solely by software (within reasonable limits - CDMA bands require different hardware). When I said the GSM variants are identical in hardware, I meant it.
Im sure someone has had you check this already but goto phone press *#*#4636*#*# scroll down there will be a drop down menu. See if you can select it.
Also att has been throttling back their users. So if you use to much net I think limit is 5gig they cut your speeds down and you want be able to connect any higher.

It should be noted that this is only for those on grandfathered unlimited data plans. Those on tiered data plans will not be throttled, but be charged an overage once your allotment is used up.
Compare nv item 6828 and 6829 between yours and your wife phone using QXDM and QPST. You will get the answer why cannot receive LTE.
did you manage to solve the issue? I am having a similar problem with my htc one m8, it locks only to edge and cannot get it to work with LTE or 3G. I have super CID and MID is 0P6B10000, however the model is M8_UL_CA which is on ATT as far as I know, I am in EU. my SIM card works on my M7 with LTE and 3G but in my M8 I got only EDGE

[Q] Groupon S5 Deal: Work on T-Mobile?

Groupon has a deal for the S5 that says it's for "Verizon and GSM Unlocked":
https://www.groupon.com/deals/gg-samsung-galaxy-s5-smartphones
Is there any way to tell what model # this is? I'm guessing that it is a generic S5 and not the T-Mobile specific SM-G900T. If that's true, then it likely doesn't have the TMo specific LTE frequencies needed for full service (I'm in the Chicago area), correct?
I really hate having to find special versions of GSM devices to make full use of T-Mobile's network...
<TAP><TAP> Is this thing on???
Unlocked for all Verizon and GSM carriers.
On the same page --> https://www.groupon.com/pages/groupon-deal-images-gg-gsm-providers
Only thing is that it probably will not be compatible with WiFi calling features, but I could be wrong.
I know it would work but I was curious about whether it was the same model they sell via T-Mobile that has their unique frequency bands (1900/2100 I believe). Groupon responded to an inquiry and said it was a Verizon model so while I can't confirm it, I'm guessing it doesn't have the extra bands needed to fully make use of T-Mobile's LTE network so it would likely drop down to HPDPA+ in many locations.
According to the reviews, its a Verizon branded phone. A couple of the reviews are from T-mo users and they claimed to have issues with the sim/network not going to LTE, instead it uses their HSPA network.
If it was me, I would not buy this. It is cheap yea, but remember that the S5 is not compatible with the new band 12.
-edit-
The Chicago area isn't getting band 12 anyways, not anytime soon that is.
I'm using a Verizon S5 with a T-mobile rom and it works perfect 4g lte and all If you end up getting it just root it then look at my view forum posts.

Unlocked Tmobile Note 8 on Sprint

I have been reading a lot of different things about doing this with no definitive answer. It looks like, as of recently, it should be as simple as popping in the sprint Sim card and it should work but I want to be sure before hand. Are there any downsides at all about using tmobile Note 8 on Sprint?
Hi there, I'm not sure but Sprint SIM cards are lock. You can try and see, I had Sprint before and try using there SIM card in my unlock tmobile Galaxy S7 Edge running the unlock S7 Edge firmware, it keep reconfiguring over and over. Maybe you might get better than me.

Sprint doesn't allow other carriers phones on their network. Unlocked or not. T-Mobile does though...
https://forum.xda-developers.com/galaxy-note-8/help/cdma-unlock-verizon-note-8-sprint-t3732364
First question would be: Does Sprint allow to use their SIM cards within non-Sprint devices? That I can't answer. Because I never used Sprint services.
The second question is: Would the T-Mobile radios work with Sprint? LTE radios would most likely work if Sprint allows you to use their SIM card with that device. When LTE is weak or not available the answer is: No. The active radios within T-Mobile and even AT&T Samsung Galaxy Note 8 are both LTE and GSM (Both 3G and 4G). Both Sprint and Verizon uses LTE and CDMA (each has their own CDMA) radios. You can't use GSM radios with Sprint and Verizon right now. Though that will end up changing as CDMA gets phased out.
To top things off each GSM carrier maybe using different frequencies with some (but not all) of their GSM radios. So changing a cellular device from a GSM carrier to another GSM carrier may have limits with GSM services.
Sprint and Verizon services have problems with international areas (outside of the USA) where LTE is weak or no LTE. The reason is that CDMA is very limit or doesn't exist in most international areas (outside of the USA). The areas that CDMA still works internationally (outside of the USA) will be phased out (mostly in the near future). Only a few places outside of the USA, like China, would CDMA not be phased out so quickly. But CDMA will end up completing phased out all together sometime in future (including in the US).
If you want to be truly Global then go for carriers that have both GSM and LTE, like T-Mobile, AT&T, etc. Then once you unlock the SIM then you can use your carrier's roaming (which don't need SIM unlock) or switch the SIM card with a carrier in that country to get service internationally. Just a side note: T-Mobile does have Unlimited 3G international roaming without any extra cost (this is subject to the type of plan you have with T-Mobile).
The only way this would work for you is if the CDMA radio is built into all Note 8 devices. If so then you just need to flash the correct radio firmware to active the correct carrier radios. But I don't believe this is the case. And this wouldn't solve the Sprint SIM lock issue.
The short answer is no. Read this thread. I thought you could just pop in an activated SIM, but it's not that simple.

ALL US Note 8s (N950U and N950U1) are identical. Same radios. Same hardware. Same everything. Only difference is the preloaded firmware. I actually think the Canadian Note 8s (N950W are the same, too, sonce they can run the N950U firmware).
So it's not an issue of missing a CDMA radio. It's an issue that Sprint will not accept the IMEI for another carrier branded Note 8 (or S8/+). You can only activate Sprint or Factory Unlocked devices on Sprint.
As Note 8 has both GSM and CDMA capabilities, why shouldn't an unlock T-Mobile work with Sprint?

On Sprints website it still does not list the tmo note 8 as compatible for BYOD. It says only the note 8 special edition is. However it is not unlikely they stopped blocking the other U.S. carrier versions. People have gotten devices to activate in the past, but with minimal network functionality. Is your Note 8 fully utilizing the LTE network?
Either way this thread brings trouble so its now closed
Sprint allows sprint capable devices such as clean sprint,Boost and such and subsidiaries that run on sprint only.
@cp1024 @Gizmoe
The Special Edition devices are the ones sold directly by Samsung as factory-unlocked models. Samsung over the years has used the term inconsistently across their site and marketing materials.
Only Sprint calls them "Special Edition", otherwise they are the U1 models, vs U for carrier branded.
Which means they as of the time this was printed will only accept this model
Maybe some others have managed to pull something off but this is official answer
my post above is how it has always been in the past
And it ends here
