Sho I thought I'd check out what you done with the firmware flash and try it on my own, I'm vzw m8 running on T-Mobile..supercid... Verizon 4.4.4 firmware now....but thought I'd try the link. Well I went to flash in hboot, and it told me wrong model Id did you do something else?
[Verizon HTC One (M8)] warwolf7:
You need to update it using ruu

_______________________________________________

Place the zip in your fastboot/adb directory on your computer.

Put the device in fastboot mode

(Volume down and power until menu appears, select fastboot using power button)

Connect the device to the computer

Enter the following commands from terminal/command prompt in the fastboot directory, one at a time:

fastboot oem rebootRUU (this puts the device in RUU mode)

fastboot flash zip firmware.zip (rename file to firmware.zip)

It will say that the update did not finish, to flush again, so repeat the above step:

fastboot flash zip firmware.zip

Very interesting thread gentlemen, and I read the whole thing! But still I feel the urge to ask if anyone might care to summarize the current state of affairs on this topic?

I have here a Verizon M8 with stock 5.0.1, software number 4.17.605.5 and baseband 1.12.20.1211. I popped in my Tmo sim and had stuff working, but experienced most of the issues discussed in this thread. I haven't rooted or S-Offed, but I don't mind doing so. Anyway, thanks in advance for any info!

i have no clue what im doing... HELP!

I have the same deal here as a lot of people, i would really enjoy having 4gLTE and sms at the same time on my phone but i realize it isn't simple to do so.

If someone has a relatively easy solution I would really enjoy any help, as my current situation isn't too well. I am ok to root the phone or whatever, but i know nothing of how to do that. If someone would care to explain/walk me through i would love it!

Hi all. Been doing a lot of reading on this forum but first time posting. Has there been any developments on converting the lollipop version m8 to T-Mobile? I'm already unlocked and s-off running the digitalhigh GPE ROM. I love the ROM, but to save $30 a month I'm willing to make some changes.

Thanks in advance.

possible solution

Hi All,

I just ordered the verizon m8 to use on tmobile and discovered this thread. Has anyone tried changing the SMS number in the device to tmobile's SMS number?

I got this idea from this thread about the verizon lumia on tmobile not being able to send texts over LTE, just gsm

http://support.t-mobile.com/thread/38915?tstart=0

Let me know if this works. My phone gets delivered tomorrow

DAMN! I was all excited to know that when, and if I leave Verizon I will have an unlocked phone that will work with other GSM carriers... Something has to be goofy cause it has the proper bands for T-Mobile. Hopefully we can get this figured out. Thanks for your input on this!

AT&T works fine because it uses H+, when being used on LTE with T-Mobile that is the issues it goes through.
[Verizon HTC One (M8)] sunilvarma:
I can confirm calls working just fine on T-Mobile LTE. Only issue so far is the ability to send texts.
[Verizon HTC One (M8)] CB620:
So you can do calls on LTE and still have LTE on the call?

LTE does not allow calls for me at all.

What is your settings. I'm using the Network app and toggle certain networks and bands.
[Verizon HTC One (M8)] swa2k4:
No calls working on lte here in Chicago..everything works great on H+ and 3g gonna use this boy for a month until i can find a tmobile model
[Verizon HTC One (M8)] sunilvarma:
My bad. I thought you said you cannot make calls in general. I'm wrong. I don't have LTE when on a call.
[Verizon HTC One (M8)] 716Rob:
Same issue, so I just been using Google Voice for my texting .
[Verizon HTC One (M8)] levilib:
AFAIK, LTE (unless the carrier is using voLTE) is a data only network. Verizon uses LTE for data and CDMA for calls and text.

Verizon seems to only allow GSM/UMTS or CDMA/LTE on the M8 at one time, there doesn't seem to be a true Global mode that allows GSM/UMTS and LTE to run at the same time.

That would explain why people are reporting either LTE or calls/texting (which, as above mentioned, only works on 2G/3G (be that CDMA or GSM))

The question is, is there a way to get around this? On the S3/S4 there was an app called phoneinfo which showed more modes than the Mobile Network settings menu. Is there such a thing for the M8?

This is quite disappointing news for me, since this is the first Verizon phone I'm aware of that has the 1800MHz LTE band, and that's the band used in Australia where I'm headed soon. I was excited about being able to finally use LTE there! I guess I'll have a choice between LTE and calls/text like all those in this thread using T-Mobile.
[Verizon HTC One (M8)] njneer:
I can confirm I have the same issue. When on LTE can't make/receive calls or texts. I had to switch from global mode to GSM only mode.

Hoping that this would be the fix for the GSM.

While you edit the data I believe
[Verizon HTC One (M8)] levilib:
That's not saying anything we didn't know already. It seems like there is no way to enable GSM and LTE at the same time, that is why we can't get calling/texting and data simultaneously.
[Verizon HTC One (M8)] must.sayim:
But we can get 3G? Or not?
[Verizon HTC One (M8)] levilib:
Yes, 3G is GSM not LTE
[Verizon HTC One (M8)] echim192:
Not sure if anyone cares yet, but on additional problem for using the verizon htc one m8 on tmobile is that you can't check for updates without a verizon sim in there. I just tried and got an error.

hoping a fix for the text messaging LTE GSM situation surfaces.. not really loving the idea of only keeping this phone until i can buy the real one when this one should be just as functional (i live in a refarmed area)
[Verizon HTC One (M8)] must.sayim:
The update is based on internet not on the Sim... So it should update directly even without a sim card
[Verizon HTC One (M8)] echim192:
Hmm really??
[Verizon HTC One (M8)] must.sayim:
Change it to the CDMA MODE and try update and send a screenshot

Without changing the SIM
[Verizon HTC One (M8)] echim192:
Hey you're right! For some reason I thought CDMA meant you had to have a verizon sim in. Turns out just being in LTE/CDMA mode is sufficient.

Worried I would miss the update for super power saving mode.

Thanks!
[Verizon HTC One (M8)] hd2newguy2011:
i got it working somehow

What I did was installed the phoneinfo app. And set it to gsm/wcdma/lte auto. And left the setting in the phone setting on global. And turn on sms over ims. I'm not sure what that does but it all seems to be working so far
[Verizon HTC One (M8)] levilib:
you beat me to it! I posted in another thread about the phoneinfo app, but I didn't know if it would work on the M8, I used it on the S3. I haven't had a chance to try it myself.

What do you mean "And turn on sms over ims"?

have you tested sending SMS and making calls?
[Verizon HTC One (M8)] hd2newguy2011:
There is a option in the settings of that app underneath the radio options. It says turn on sms over ims. Not sure if that made it work or not but I'm leaving it on. I did it last night and all was working but it stopped in the morning. So I put those back in and I'll see how long before it changes back. But yes calls sms as and mms all at working. I'm not using the stock sms app as I couldn't get mms working in that app. So I'm using textra for now. I'll keep posting anymore info that I have.
[Verizon HTC One (M8)] levilib:
So can you confirm that LTE and GSM work simultaneously?

If yes, you can close a few threads!
[Verizon HTC One (M8)] seanyuan62:
So absolutely no problems including sending mms with the stock messages if we use it on T-Mobile just 3G and not LTE right?
[Verizon HTC One (M8)] hd2newguy2011:
The sms and mms are working with me. I am using textra as my sms app. I can't send mms through the stock HTC messages app for some reason. But as of now I have lte and I am sending mms and sms but I'm using textra and the settings I posted earlier in the phone info app
[Verizon HTC One (M8)] levilib:
So now we just have to figure out what the deal with the native SMS app is.

Are you sure textra isn't routing messages over data and you really are having the same issue as everyone else i.e. just getting LTE and no 2G/3G calls and text?

have you tried making a voice call?
[Verizon HTC One (M8)] hd2newguy2011:
Actually it stopped working after I left my house. And it switched from global to gsm in the setting for mobile data. We need something to keep the settings from automatically switching. I'm going to freeze the stock sms app and see what happens. Maybe that has something to do with it.

---------- Post added at 09:33 PM ---------- Previous post was at 09:31 PM ----------

I definitely had it working for about a glad hour with no issues. Somehow it stopped by either switching cell towers or just by a certain amount of time. The settings changed for me in the mobile data settings on the phone. But the settings in phone info app stayed. Weird. There has to be a way to get it working all the time.
[Verizon HTC One (M8)] levilib:
Can you try going back into the phone info app and choose the GSM/lte mode, then try use lte data and make a call, see if it even works for a few min
[Verizon HTC One (M8)] alhadee12:

I don't even get LTE in my area. I like the price also, but will likely move away from them as well.
[Verizon HTC One (M8)] blacknet101:

Good luck on the move, I'm sure it'll be better.
[Verizon HTC One (M8)] echim192:
omg this works!! don't bother changing phone settting to "global" seems like the app over rides it.

I can send texts over LTE, and when i go to make a call it auto switches to "H+"

UPDATE: No it does't work. Sorry.
[Verizon HTC One (M8)] hd2newguy2011:
There is no gsm/lte mode. That's what the problem is I think. There is gsm/wcdma/lte mode. That's the closest one. That's what's working for me for about a half hour at a time
[Verizon HTC One (M8)] levilib:
which app? phoneinfo?

bottom line: are you getting T-Mobile LTE as well as calling and texting?

try making a call and browsing the web, is it still showing LTE?

---------- Post added at 06:38 PM ---------- Previous post was at 06:36 PM ----------

That's the mode I had in mind, try switching to it, then within you half hour "grace period" try make a call and use the internet at the same time, see if it's still on LTE

(FYI: WCDMA and UMTS are for all intensive purposes the same thing, WCDMA is 3G GSM)
[Verizon HTC One (M8)] echim192:
Yeah phoneinfo. But maybe I spoke too soon. Now texts are not going through, and calls aren't either. Maybe I'll just keep it on GSM/UTMS mode for now
[Verizon HTC One (M8)] hd2newguy2011:
When I make a call it goes to h. But my t-mobile phone did that also. I don't ever remember my t-mobile phone getting lte data when on a phone call,it was always h.
[Verizon HTC One (M8)] echim192:
Okay using phoneinfo, everything works fine, but after a few minutes it stops working and it's as if the phone is on "Lte only" mode had phone info never been installed. My voicemail notification disappeared after a while which signaled to me that the "Grace period" had expired and that i was no longer able to receive/send calls.

Open phone info, even though it's already been set to the GSM/WCDMA/LTE mode, and LTE stays lit up, but my voicemail icon reappears, I can send text messages. When I make a call, it drops down to H. When I hang up, LTE lights back up again, but the voicemail icon disappeared suggesting the call tripped the grace period?

Just trying to give some raw data.

---------- Post added at 10:54 PM ---------- Previous post was at 10:48 PM ----------

also, Not sure if this was stupid, but I tried updatingt he SMSC number to tmobile's provided number to see if this would help things. I'll report after some usage time.
[Verizon HTC One (M8)] CB620:
Tested the app and the settings I still could not make calls. It force closes every time.
[Verizon HTC One (M8)] levilib:
Not good news, I guess we'll have to wait till Verizon/HTC push an update that fixes this, or people figure out a fix via root

---------- Post added at 08:09 PM ---------- Previous post was at 08:07 PM ----------

I'm curious if this is just a problem with T-Mobile, I've heard of carriers taking measures to stop US GSM networks being used but international GSM networks will work, based on what's been discovered in this thread, my hopes aren't high, but I'm headed to Australia next week, I'll let you know if anything's different there.
[Verizon HTC One (M8)] pcsfguy:
Do you guys think there will eventually be a fix for the LTE / no SMS issue? I'm really tempted to get this phone while its on sale at Verizon, but no LTE is a dealbreaker for me
[Verizon HTC One (M8)] echim192:
It has LTE, and it works great. I pulled down like 20 mbps. Just have to enable it.
[Verizon HTC One (M8)] levilib:
We know it has LTE, the discussion of this thread is whether or not LTE and GSM run simultaneously
[Verizon HTC One (M8)] levilib:
On a side note, all those using this device on T-Mobile HSPA (not LTE), what speeds are you getting?

The specs on HTC's website seem to indicate that the VZW model only has 14.4mbps HSPA, while the T-Mobile version has 42mbps.

Can someone run a speed test? I'm curious to know if it's really limited to 14.4.

Quote from HTC.com:
[Verizon HTC One (M8)] 123421342:
LTE is a gsm technology, the M7 had this issue as well. I don't think LTE will work properly on a verizon rom.
[Verizon HTC One (M8)] levilib:
True, but as people have been reporting in this thread (and others) that they can't seem to get LTE to work on T-Mobile while getting GSM 2G and 3G to work at the same time, Practically, calls and texts run through 3G/2G and not 4G LTE. So, although LTE is GSM technology, the phone is npt connected to T-Mobile's GSM network and therefore no calling and texting, until it is switched back to GSM/UMTS mode.

what type of speeds do you get with hspa+? an earlier post mentioned it maxed out at ~14mb.

[Verizon HTC One (M8)] seanyuan62:

I don't mind HSPA+, I like the phone way too much. Besides I'm coming from sprint where my data speeds were like 2mbps. I'm going to hold on to it until they come out with a tmobile rom.
[Verizon HTC One (M8)] seanyuan62:
So for those using it on GSM/UMTS, did you have to put in custom apn settings? When I plugged in my sim it appeared to get data, but when i look in the apn list all it says is one apn called Verizon Data or something with no settings entered...

If so, do you mind sharing your settings to get sms, mms, and everything working perfectly? (I'm talking without LTE which is why I am assuming everything works perfectly on 3G)
[Verizon HTC One (M8)] lourock21:
Htc one M8

All I did was turned on GSM/UMTS and download an app called Textra to manage my SMS and it works fine on HSPA+. I haven't had any other problems
[Verizon HTC One (M8)] seanyuan62:
Okay that makes sense. So has anyone figured out how to send mms through the stock messages app? I tried reducing the max mms size in the settings, but it didn't helo
[Verizon HTC One (M8)] levilib:
Does sending SMS from the native app not work even when not on lte?
[Verizon HTC One (M8)] lourock21:
Htc one m8

Nope, I'm pretty sure eventually someone will figure it out
[Verizon HTC One (M8)] levilib:
I'm confused, If native texting isn't working on both HSPA and LTE, then what's the difference?

Are voice calls working on one and not the other?

If textra is working when native app isn't, I'm lead to believe that textra uses data not cellular SMS
[Verizon HTC One (M8)] lourock21:
I meant to say mms is not working on HSPA using the native messaging app. Regular SMS working fine
[Verizon HTC One (M8)] seanyuan62:
I must be doing something wrong. I have 3-4 bars of 3G/H but my speeds are pretty erratic and usually ver slow
[Verizon HTC One (M8)] blacknet101:
same thing was happening to me, I gave up trying to make things work, until we have s-off we probably wont be able to use LTE and messages and calls at the same time..I was getting HSPA speeds but it was too slow in my area..Using my verizon sim card right now, and I am loving the LTE from Verizon but it sucks that the HTC One wasn't working like I wanted it.
