[Q] Need to convert AT&T M8 into Tmobile M8

I have never gotten my MMS to work on my Unlocked AT&T HTC One M8. I recently read that this is a problem because I'm not using a Tmobile branded M8, and that if I updated to a Tmobile ROM it would fix my MMS issues.

I have a solution that will work however I offer this with no-warranty and for a use at your own risk, however I can say I have done this for maybe about 60 T-Mobile customers who brought their HTC One m7 from AT&T. I have done this as well. HTC m7 phone are all built with the exact same parts, the only thing that makes the phone operate differently is the firmware for the baseband, and of course the rom. However HTC offer's a RUU (Rom Upgrade Utility) right on their support page. This reinstalls the android os, along with new baseband and firmware versions. All you have to do is run the T-Mobile HTC One m7 RUU that is on the HTC website. You can use the link here to download the RUU from the HTC website. It generally about 1GB in file size, as this is not just the Android OS, but this is the software for the phone's hardware to flash it from an AT&T HTC One to a T-Mobile HTC One.This will also enable your phone to receive Over-The-Air updates from T-Mobile as well. Again I and T-Mobile will not support this. However I can say from personal experience and also on behalf of the people I done this for that it works. *Also you will get to enjoy the T-Mobile Wi-Fi Calling as well. Your phone will act and perform just like the T-Mobile version will after this. After all they all have the exact same parts under the hood. Just different firmware, and operating systems. This converts it all over to T-Mobile

I have since rooted my device, unlocked the bootloader, done S-OFF, and set CID to SuperCid.
I just wan't to confirm that I'm doing the right thing so I don't end up bricking my phone.
Do I need to change the MID or CID of my device?
Do I need to update through RUU to a Tmobile ROM in order to make make all the relevant firmware changes to convert my M8 into a Tmobile branded phone rather than AT&T or can I just flash through the the Recovery and flash a Tmobile ROM?
My understanding is that reinstalling the Tmobile ROM will keep S-OFF, SuperCid, and Unlocked Bootloader, but will NOT keep Root. Is this correct? Will it keep my custom recovery?
Sorry for all the questions. Thank you for your time!

The information you quoted is incorrect. The AT&T and T-Mobile versions are two different hardware versions. AT&T M8 being m8_ul_ca and T-Mobile being m8_ul. They do not have the same network compatibility.
At&t - 0P6B1200 supported bands (in MHz):
3G=850, 1900, 2100
LTE=700, 850, 1700, 1800, 1900, 2100, 2600
T-Mobile - 0P6B1300 supported bands:
3G=850, 1700, 1900, 2100
LTE=700, 1700, 2100
As you can see, T-mobile has an extra HSPA band that AT&T doesn't support. This is also why the AT&T model does not support 42.2Mb per second HSPA+ downloads while the T Mobile version does. AT&T maxes out at 21.1Mb over HSPA. You'll also note that the AT&T version supports more LTE bands, however, those are bands that T-Mobile does not operate it's LTE network on so really it doesn't help. Long story short the devices are actually not the same.
Now, you can still operate an AT&T model on T-Mobile's network with a large degree of success depending on your coverage area and what network bands are currently being utilized. The 700MHz band has not been switched on everywhere for T-Mobile just yet so you would be limited to only two bands of LTE support.
All that being said, if you do flash a T-Mobile RUU, you will have wifi calling support you will have the correct device and network settings for T-Mobile, including MMS, and you may notice little to no loss of network performance on your device, however, you may notice significant loss of performance. It depends solely on the network in your area. After flashing a RUU, you will have the T-Mobile software & firmware as well as maintain your s-off status, but you will not effect supported network bands. Also, if you want to receive OTA updates you will need to change your model ID aka MID.

Ok I understand. I wasn't aware that the AT&T model didn't go up to the same data rates as the Tmobile one. The only reason I bought the AT&T one was because I liked the color better
So as far as using the T-Mobile RUU, I'm set and don't need to make any further adjustments (ex: MID, CID, Bootloader Lock, or S-Off)?
If I want to receive OTA updates from tmobile after changing the MID do I need to get S-Off or relock the bootloader or change CID?

You need to change your MID [how to] change your MID without an eng bootloader and then run the RUU. I don't think changing the CID is necessary but you can do that too if you want.
Once you're S-OFF you don't ever have to relock the bootloader for anything. Just leave it unlocked.
If you don't want to do RUU then just restore a stock T-Mobile nandroid, preferably an earlier version. That way you can see if your device does the OTA updates like it's supposed too. For me, I don't know if anyone else had the problem, I had to flash the first OTA manually and then the device did the rest automatically. This was with a conversion from International to Developer Edition.

So as far as Im reading I need to LOCK my bootloader in order to use the Tmobile RUU. Yet you say I just need to change my MID. Can you confirm that the RUU will still work on an unlocked bootloader?
Would I still need to change my MID if I just used Recovery to flash a Tmobile ROM?
EDIT:
Just changed my MID to 0P6B13000 (Tmobile USA)
Am I all good to go now to use the RUU without bricking?

Yeah go for it. Shouldn't brick unless unforeseen connection issue with your PC.
*edit
Also keep in mind only HSPA+ speeds will be affected. If you are in an area with T-Mobile LTE support, speeds will not be affected. So you may be lucky and have no issues whatsoever.

My area is predominately LTE =]
So I just downloaded this TMOUS-M8-3.32.531.2-Stock-TWRP.zip
However, I found this in a thread on xda:
3.16 hboot = 1.12 / 1.54 software
3.18 hboot = 2.22 software
3.19 hboot = 3.xx software
Click to expand...

Since my hboot currently is 3.16 does that mean I can only flash 1.12/1.54? And not the 3.32.531.2 I downloaded since it corresponds to 3.19 hboot?

Personally I would just flash the T -Mobile 3.32 RUU and be done with it
http://dl3.htc.com/application/RUU_...G_20.56.4198.02_F_release_394971_signed_2.exe
*edit
Well maybe not done with it, I'd still flash supersu, rw mod or custom kernel, and remove the bloat, but I think you get what I mean.

Having so much trouble getting the RUU Installer to work. Tried it on 2 different Windows computers (8.1 and 7) with the installer always exiting. Does the RUU do anything special that flashing through cmd prompt or recoveries wont do? At this point I'd much rather do that.

Like I said previously, I'd personally go for an older version first. That way you can test to make sure the conversion is 100% by letting the device do the OTA updates. What's the point of converting straight to the latest version and leaving yourself unsure whether OTA will work once Lollipop comes out?
I'd go for one of the 1.xx.xxx.x versions and update it to the latest, but that's me...Just a thought/suggestion.

My apologies, I wasn't totally clear with my intentions. I just wanted to flash the stock latest ROM from T-mobile that I knew would fix my MMS issue. Then I would make a backup of that so I could always recover my phone to that point. I was always going to flash custom ROMs based off Tmobile base firmware, just wanted to have a fallback backup.

I know what the intention is, I'm just stating what I personally would have done. Like I said before, when I converted to Dev Edition I had to manually install the OTA and flash the firmware twice before my device picked up the newest OTA updates and installed it automatically. Don't know why this is...Which is why I personally go back at least 2 or so versions prior to the latest version available to test and make sure that my device can do the OTA updates. You don't have to do this, just figured it would be good to know all is in working order for when 5.0 launches, else you'd probably have to install/flash manually OR go back a version in order for it to update automatically. It's fine either way I suppose, no "biggie".
RUU is the easiest way to do it but you can also just head over to the collection thread, download the latest nandroid backup from there and restore it in TWRP. Then head over to the update thread you'll find a collection of OTA.zip files. Download the one for T-Mobile and install it. You can also extract the firmware.zip from the OTA.zip and flash that in RUU mode(Twice flash) just to make sure the firmware is all in place.
You'll also then have a downloaded backup for nandroid(2.22.531.5) and you'll also have the stock recovery(Which is available in the firmware.zip file) for future references.
Collection for stock nandroid backups Latest nandroid for x.xx.531.x T-Mobile is 2.22.531.5 So you'll have to do OTA's anyways if you want that one.
OTA Zip collection Yours will be under "branded"
Afterwards you can just flash custom recovery and make a nandroid backup of 3.32.531.x for T-Mobile then you're set. You don't have to worry about making a backup of stock recovery as it is in the firmware.zip file like previously mentioned.
All that said, like mentioned before, RUU is probably the easiest way. Try an older version, should be available in the T-Mobile section.

No Support by Sunshine!

If Sunshine is the only way to achieve S-OFF, But my device isn't supported does this mean i just have to cry about my S-ON One M8?

If you are that disappointed then yes cry all you like ! If that's a disappointment you will cry about i wonder what you will do when you get a real disappointment in life ?!
They are working on a update maybe that will cheer you up

Just so you know, The HTC One M7 was out for nearly 6 months without S-Off and it never stopped the developers form creating dozens of Roms and the development of the phone went on without any problems. All S-Off is really needed for is converting a phone to a different branding or carrier. Or to downgrade firmware. In most cases the phone will function and update just fine without s-off. All you need is an unlocked bootloader and custom recovery to enjoy most of the custom roms available to this device.

That was the main thing I needed, a new carrier. I'm sure it will happen eventually for my version just a matter of waiting for it!
already unlocked bootloader with custom recovery, running SlimKat atm, just the carrier issue.

What is the phone not doing on your current carrier that you think a firmware / CID MID change will fix ?

Maybe he means SIM unlock it ?

I have the Sim unlocked Developers Edition so I'm not sure whats needed for that. But yeah S-Off is nice even at $25. I hope they get it updated for you soon.

Definitely worth it. No Issues paying for s-off. Hope they are working hard lay

I don't know what you're talking about that it won't work? FYI I'm running Viper Rom 3.2.1 and my device is supported. Or did you mean that you already bought the license and your phone says that it's still s-on?

help at all?

If all you desperately need sim unlock, and you're going to have to pay anyways, have you checked the usual sim unlock services? Most of those only cost like $10-15 and you'd get to switch carriers while you're waiting for sunshine to update.
With that and the right kernel/rom combo you'd get most of what s-off gets you anyways, with the exception of downgrading firmware, etc. but really how often are you going to do that? Just something to consider I suppose.

Incorrect. You can't flash new firmware unless your MID and CID match the new version. With S-Off, you can always be on top of the new firmware from any carrier. (unless you are on Sprint or Verizon). For instance, AT&T is still on the old stuff. With S-Off, AT&T users can be on the newest 4.4.4
Also, I was on 4.4.4 (telus in canada) two months before my carrier updated. S-Off gives you full freedom.
Also, S-Off and SIM unlock are two totally separate things. So there is also that.

Three services have said they can't get an unlock code for my M8... Can an M8 be HardLocked like a Sony M2? Does anyone know where I might find the unlock counter is present on HTC?

Most likely your phone just isn't in their databases yet. I ran into that exact same thing when I had my OneX+. It's basically just a waiting game until they get the new databases that have your code in them. Back when I had my X+ it took about 2-3 weeks before anyone got the newest databases. It sucks, but all you can really do at that point is just wait. Which, again, definitely sucks.

[Q] I need some help with my Mobile Data

So I just got my phone around a month ago and what I noticed is that I can't get a connectin better than Edge.Before this phone I had a HTC One X,and the mobile data was working perfecly fine and now its just an E that annoys me since the internet is really really slow.I wonder what could cause this problem.

I don't know anything about that phone, and I'd caution against applying mods intended for another phone, as they can cause permanent damage to your device.
Its probably as simple a matter of having the wrong M8 version for your carrier. But nobody can help unless you answer the question previously posed to you: What carrier/region version (what CID) of the M8 do you have???

Did you purchase the phone used?
If so, this is yet another important detail that you failed to mention. Honestly, you are making it very difficult to help by failing to provide any details, failing to answer questions.
Do an adb getvar all (delete your IMEI and serial number, as these are private info) and post the output here.
Also, does the bootloader screen say UNLOCKED, RELOCKED, or LOCKED near the top?

The phone is s-off, and also the CID and MID have been modded to so that most M8 firmware will probably flash.
Find the firmware (and make sure its Lollipop) for the version that has a radio baseband that supports the bands needed for your network. Flash that firmware, and you should be good for mobile data (as long as you enter the proper APN also).

ROM probably won't make a difference. You probably have a radio baseband (firmware, separate from ROM software) installed that does not support your carrier's HSPA and LTE bands.
---------- Post added at 10:27 AM ---------- Previous post was at 10:18 AM ----------
According to this website, Moldcell uses 2600 MHZ for LTE, and 2100 MHz for HSPA (WCDMA or 3G).
And our radio baseband looks to be for the "Euro" firmware 4.16.401, which should support the Moldcell bands.
Are you sure you have the APN for your carrier entered properly; and that your SIM works with 3G/4G on another phone?

APN is probably correct, as I'm pretty sure that if the APN was wrong, even EDGE would not work. But I figured I'd mention it just to be sure.
If the SIM worked on your old phone, that eliminates the possibility there is an issue with your account or network.
So I'm not really sure what the issue could be. By everything I've looked at, 3G should work. It might still be worthwhile to try a different radio baseband.

Flash a different firmware package, which contains radio baseband: http://forum.xda-developers.com/showthread.php?t=2696282
I'd recommend sticking with 4.xx (Lollipop) firmware.
You can always flash back to 4.16.401 firmware (appears to be your current firmware), if flashing other firmware doesn't help.

Unlock LTE (4G) bands 3,5,40 (HTC One M8)

Hello,
I am using Developer edition ROM (Unlocked,Stock) with the following details:
version-baseband: 1.29.214500021.24_2G
version-main: 6.12.1540.4
version-misc: PVT SHIP S-OFF
product: m8_ul

I stay in INDIA and it is not showing any 4G networks here. I want unlock all the LTE bands (3(1800MHZ),5(850MHZ),40(2300MHZ)) operating here. I tried some threads but its I am not able to unlock the bands. Please help.
I refered this thread: http://forum.xda-developers.com/verizon-htc-one-m8/general/tested-verizon-m8-unlock-lte-band-t3327694 but I am not able to enter the diag mode.
Thanks in advance.

I have sprint htc one m8 , i will try this and let you know if that wotks or not,and if you figure it out someplace else ,please tell me how you did it.

The previously posted method works for Verizon, and I believe Sprint.
Unfortunately for the OP, it doesn't work on any other variants. NV values are locked, and will return to stock upon reboot. For other variants, the only way to change band support is to flash another CIDs radio baseband firmware. But I don't know of any version that supports all the bands stated.

How to figure out if M8 is US or EU model

Hello all,
I just got a refurbished M8 from China and after many hours reading tons of documents I am still struggling to figure out if it is a EU model as advertised or a US one.
On the back of the phone it says Model 0P6B100 but the MID (0P6B120), the model string M8_UL_CA and probably more important the IMEI point to an AT&T version. Now the OS/firmware seems to be the stock EU one (version 3.28.401.6), there is no AT&T logo or app anywhere.
Since you can pretty much change everything in software I'm not sure which of the above information I can really trust.
Is there any way to tell for sure if the device is EU or US?
If it is US is it by design limited to the US 4G bands or will using an EU firmware make it use all the EU bands?
I can post the full bootloader information if it helps.
Edit:
Forgot to mention: the CID came set to 11111111
Thanks

This means little. We've seen a lot of M8 devices that have had their back covers replaced; usually to remove the US carrier logos - which reinforces the notion that it was originally ATT. Its what is inside the phone that matters, so we need to go by the getvar data.
but the MID (0P6B120), the model string M8_UL_CA and probably more important the IMEI point to an AT&T version. Now the OS/firmware seems to be the stock EU one (version 3.28.401.6), there is no AT&T logo or app anywhere.
MID number is easy to change with s-off, but the product ID (M8_UL_CA) I've never seen changed, and is reliable to go by.
Likewise, OS number is easy to change with s-off. First can you confirm where you got the OS number, is it from the bootloader screen (which is the correct place to get it)? If so, former owner or the reseller probably flashed Euro 401 firmware/software in order to "convert" it to Euro, and remove all ATT branding, give it the proper Euro band support, etc.
Since you can pretty much change everything in software I'm not sure which of the above information I can really trust.
True that CID, MID and OS number can be changed. But as mentioned, I've never seen the product ID (M8_UL_CA in this case) changed. So that should be reliable to go by, making it the ATT version, or much less likely the US Developer's Edition.
Is there any way to tell for sure if the device is EU or US?
If it is US is it by design limited to the US 4G bands or will using an EU firmware make it use all the EU bands?
If the OS number you gave was taken from the bootloader screen, its already had Euro firmware flashed. Does it work on your carrier's LTE network currently?
I can post the full bootloader information if it helps. If you know how, do fastboot getvar all, and post the results (delete IMEI and serial numer before posting). But I'm pretty sure this is an ATT version that has been modified, and back cover replaced.
Is the phone s-off?

Note about version-main: the phone came with 3.28.401.6 (same in bootloader and information from phone) but it refused to install OTA updates so I flashed a stock 3.28.401.7 after changing CID and MID to EU values. This allowed OTA to process all the way up to Lollipop and this is where problems started: the Apps store decided that the device is not compatibe with applications which I was able to install on KK without problems and the MM OTA does not show up when I check for updates.
I just got my nano SIM and initial tests shows the phone connecting to 4G but I have no clue which band it uses (any way to check???)... it also switches back and forth between 3G and 4G a bit too much for me but I am in a rural area so it might be normal. I will have to do some side by side comparison with my wife's Wiko which I know to be working fine.
Right now I'm in the middle of bringing the phone back into the state I received it, just have to flash to 3.28.401.6 firmware. Or would it make more sense to get a stock MM right away (I don't care about the data)?

Something is strange here. The MID isn't for Euro version now. It should be 0P6B10000.
And the fact its not, should prevent the Euro OTA from installing (possibly even from giving the update notification and downloading).
Further, if you did OTA update to Euro Lollipop, the main version would say 4.16.401.10 (or .13).
Something doesn't add up here. I think you did something wrong, or may have some of the steps confused.

It would probably make the most sense to find out what LTE band(s) your carrier uses. From there, I can see if your firmware version supports that band(s).

My recommendation would be to properly change to the Euro MID using this guide (is this how you changed the MID before?): http://forum.xda-developers.com/showthread.php?t=2708581
Then RUU to Marshmallow using this post: http://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
RUU will wipe the phone. But as you said, you don't care about that. And since you are having other issue (with Play store), the RUU may fix that.
RUU is a complete stock Euro image; re-writes every partition. Nice clean install, and the best way to update (as long as you don't mind the phone being wiped).

This is because I started to bring the phone back to the weird "China config" having the AT&T MID with an Euro FW.
To get the OTA to work I did set it to 0P6B10000 with a CID of HTC__203 but seems there is an additional check somewhere which disabled the MM upgrade from showing up.

Does your statement imply that the EU and US versions use the same hardware and that the used frequencies only dependent on the installed firmware?
Because at the end it all boils down to: can I use the phone reasonably well in Europe or should I ask for an exchange / refund.

You should always describe all the exact steps, and what you have done to the device (in detail, be specific), in order for folks to help you. Otherwise, its really confusing. You want to make it easier for folks to help you, not harder!

I've never seen such a check, and don't believe this assumption is correct. There are lots of glitches that can happen in the system, that can prevent an OTA. That is likely what happened.

Which to me does not say you downgraded to KK. And even if you said so, you'd have to be specific that you downgraded both the firmware and OS (by RUU? Or by flashing firmware.zip and a Kitkat TWRP backup?). Again, I'm just saying you should always try to provide the proper and complete details about what you have done, in order for us to help you. Otherwise, its confusing and makes it harder for us to help you. Already wasted time trying to figure out what you did, and asking you about it.

That is correct. The hardware is the same in this case (ATT and EU) and the band support is set in radio baseband firmware. Meaning, if you have a Euro radio firmware installed, it should support the bands specified for the Euro version.

Based on the specs here, the Euro firmware does not support LTE 700 MHz.
You may have better results with the Asia radio firmware, which supports all the LTE bands you stated. But that would be assuming its the 700 MHz LTE band that is being used in your area, and the missing support is what is causing the problem (which may or may not be true).

Hard to say for certain, but again, you may flash the Asia radio, and see if that helps.

SuperCID 11111111 is fine. SuperCID basically "passes" any CID check by the RUUs and OTAs, that is what makes it super!
