Is there Stock Sense or GPE with OTA for T-Mobile M8?

Hey guys!
I'm European user. Few months ago I bought sealed 32GB HTC M8 from Ebay, not realising that all 32GB ones are T-Mobile branded. It came with unlock code and pinch of disappointment. The thing is, in Bulgaria there even isn't T-Mobile as an option and I want to get rid of all the T-Mobile bloatware on my phone.
I've already unlocked my bootloader, rooted and sunshine s-off my phone. I'm considering either going stock sense or going GPE (so far I've had 2 Nexus devices last 4 years, loved stock) but I want to keep OTA and I don't seem to be able to find neither GPE 5.0.1 RUU nor Stock Sense RUU with OTA for T-Mobile Can you give me any directions - I do realise that after flashing new rom, I will have to put back a stock recovery.

If you do a full GPE conversion including the MID and CID you should be able to receive OTAs. Try this thread. READ THE WHOLE SET OF INSTRUCTIONS!!! NOBODY IS RESPONSIBLE FOR YOUR DEVICE GETTING BRICKED!!!
http://forum.xda-developers.com/showthread.php?t=2708589
I've actually done this conversion and later switched back to a stock Sense build. Make sure you read the entire set of instructions.

Thanks for the info, Phil! By "I went back to stock sense“ do you mean T-mobile stock room or stock international unbranded rom?

Stock T-mobile. The GPE didn't get very good signal here. On average I had half the bars and trouble keeping LTE.

You are not the first one that complains from GPE conversion signal issues around here... Is it per device basis or it's just in US that GPE devices have issues?

I've only had experience on the T-Mobile version of the phone converted to GPe, running on T-mobile USA towers.

I converted my device using the RUU from the thread you sent me. I seem to have good coverage but I kinda miss some of the HTC Sense apps. I thought that at least I would be able to download the HTC camera app. I will probably find it's apk somewhere as the stock google camera app seems worse.

[Australia] HTC 10 Australian

Hi guys,
I got my HTC 10 last week - phone is a big improvement from the m8.
I am running Telstra's latest firmware - Have s-off already...
Telstra's latest firmware is 1.53.841.6 with Leedroid ROM - have been trying to get VOLTE.
I never got VOLTE with stock because I rooted so fast and S-OFF and installed custom ROMs.
So I had to install stock system image 1.53.841.6, reinstall stock recovery and factory reset and VOLTE icon shows up instantly. Install TWRP and VOLTE remains. But if you install a custom rom and do a full wipe seem to lose VOLTE. Also have to have the telstra firmware to VOLTE to work, I tried with WWE and no go. Also had to ring up telstra as it wasn't activated. So if you are having trouble getting it - might be best to double check. Even though my provisioned flag was on. *#*#4636#*#* to check - tap phone info.
@xlrate reported not wiping data and installing VIPER was able to keep VOLTE. (Updated the customize folder in the rom with my Telstra back up, also the build prop to do this) Also TELST001 cid has to be on.
Has anyone got VOLTE working on a custom ROM on WWE Firmware?
So Aussies... Who's got their new HTC 10?

Telstra OREO update
http://fotadl-az.htc.com/secure/OTA....48.841.31_release_519847tp9bagwfkglchg5u.zip
@Sneakyghost isn't doing the firmware updates anymore.
If you need to use the firmware.zip out of the OREO zip and need to a custom recovery either replace the recovery.img with twrp.img (rename it of course) in the firmware.zip - or flash one after installation.

I got mine about a month ago.. All I've done so far is root it.. (even after all these years, it still sounds wrong)
I normally run ARHD, but, Mike hasn't mentioned developing for the 10, so, I'm stuck atm, not really interested in running a massively modded ROM. But, last night the OTA notification popped up for 1.53.841.6.. So, I'm going to have to do something - the notification is annoying me. So, I guess I have to work out how to update it.
I hadn't even considered the VoLTE requirements.. I just assumed it would all work, even on a custom ROM. 4G did, I didn't think this would be any different.
Is VoLTE worth hanging on to? I don't really get it.. Is it like VOIP for mobiles?

I have had VoLTE working with Leedroid after I used the telstra 1.53 system/customize & parts of the build.prop on the 1.30 base... Haven't been able to get it working on 1.80 base.
Have had to use the telstra firmware for it work, doesn't work on WWE. So it is kinda a pain to get working.
VoLTE is better call quality and if you are on a call you can use LTE/4g to use the internet... Without VoLTE when on calls your phone 3g
EDIT - don't think OTA will work since you are rooted unless you went systemless root

I guess I don't 'appreciate' VoLTE as much as I should, because I rarely make phone calls..
Sadly, not Systemless root. So, I think I need to go back to stock, update and re-root. It's not something I've had to worry about before. So, it's kinda frustrating, and a little too complicated for me to totally understand.
I was going to de-brand it, and just run the WWE RUU.. But, maybe I'll wait for the 1.80 Telstra update and worry about it then.
I got rid of the notification

Anyone experiencing an issue with NFC? While on stock 1.21.841.8 (and locked), worked without issue. Since updating to 1.53.841.6 (and unlocked), can't read my Opal card now ie no vibration, no sound, no anything. Haven't tested my tap & pay banking app yet (which did work without issue prior to updating).

Yes I also had and issue with NFC. Would not read opal card and was an absolute pain to try and read my Amex and Visa card.
Ended up getting another issue with it and returned the phone under warranty for NFC and the other issue.
Still waiting to get a phone back ?

Yeah NFC doesn't work with mine now on 1.53.
I did get a vibrate and a sound when I was on earlier firmware but not now.
Just hoping that the 1.8 update fixes this stuff.......

Tried reflashing the 1.53 firmware again (twice) to see if it fixes it, but it's still not working ie Can switch it on and off, but it does not respond to my opal card.
It's only taken Telstra until this month to push out 1.53, so who knows when (or if) 1.80 will happen. Now I'm trying to decide whether it's worth sending back for another handset or waiting to see if the next OTA will fix it. My biggest concern is that the replacement could be on 1.21 and I could possibly end up with the same issue all over again!

I just tried to NFC on 1.53 and it isn't working very well, hardly at all. I got it to work 3 times in about 15 mins...
Previously I think when I was on 1.30 firmware it was working well before but just had to hold it near the head phone jack.
Any Telstra users want to test out the Telstra firmwares

Make sure you back-up the rom & back up internal storage refer to later posts in that thread.

https://crowdsupport.telstra.com.au/t5/Device-Updates/Software-Updates-01-07-2016/td-p/585953 Telstra 1.80.841.8 firmware is coming 25-Jul
Leedroid is the best rom for Telstra users. Running it myself and working perfectly, now supports Telstra with carrier support & VoLTE working - thanks @LeeDroid
*Only works on Telstra firmware.

Install Ice yesterday (only got my phone Friday ), really like it over the stock rom.
Some people complained about the LED but I like it. My only complaint about my M8 was how bright the LED was specially in the dark when you're trying to get to sleep.
Another problem I'm having is file transfers freeze when using a USB 2 port on Windows 10.
I like my new M10 but not sure if I like it over the M8 as of yet. I preferred the speaker arrangement on the M8 and having the home, back buttons etc on the screen rather then down the bottom.
I have to admit I'm not a fan of the "Samsung" look at all which is why I bought HTC in the past to begin with. I didn't want to be a part of the flock.

Hey guys,
I'm looking to get the 10 but imported, could someone (especially looking for someone with Optus) check their box to see what specific model it is (e.g. 10h or 10u)?
Thanks guys

The Telstra model is a HTC 10h

ICE (InsertCoin) v2.0.6 supports Telstra also now too. Thanks @baadnewz

Found out that Telstra's policy for DOA/ELF replacements are within 30 days of purchase. Since a return will result in a repair, I'll wait to see if the OTA will fix the NFC issue first before sending back.
Has anyone experienced an NFC issue on Telstra stock, only to have it disappear after switching to a cusom ROM?

Has anyone rooted a Bell Canada HTC 10?

Hi everyone,
I've been researching for a couple days and I'm pretty much ready to root my phone. I have the Bell Canada version. All I want to do is unlock the bootloader, root it, and install Xposed. From what I can tell, I shouldn't have any problems. But I've been seeing a lot about the radio not working, and I'm concerned I might be screwing myself since there is no RUU for the international version of the HTC 10. Which means, as far as I can tell, that if I screw up my phone there's no going back. I haven't seen many threads addressing specifically the Bell/international version, so I want to be clear before I try anything. I have much experience rooting phones, but I'm new to HTC and it seems much more complicated and risky.
So I have a few questions:
- Has anyone successfully rooted the Bell/international variant of the HTC 10 without issues or radio loss?
- Further, has anyone gotten Xposed framework working?
- Is there a way to revert the phone back to stock/fully functioning in the case that the radio stops working or some other problems arise?
Thanks in advance.

I plan on getting one soon and root it. Would be fun to know if someone did it already.

Were you guys able to root and/or flash a ROM on the Bell model?

I am running Leeroid ROM on my Bell HTC 10. Very easy. Unlock bootloader, install twrp with fastboot and you're gold
Xposed works great too. Never had an issue with radio since rooting. I do have a minor problem which only started happening since i removed the rom encryption and my lte wont work until i go into mobile networks and reset apn to default. Once i do that my lte works like normal until i reboot and have to repeat the 10 second process.
And you can always save a twrp backup of your stock ROM if you want to go back.

sweet, thanks for confirming! Did you manage to get a Sharp display by chance? I have a feeling that literally all of the Bell ones are of Tianma.

Bell user here. I'm on stock rom with latest update with some mods. Phone runs pretty good now,
1.90.666.4 OS
Sunshine > $25 dollar paypal (S-OFF)
TWRP for recovery
AcoustiX_Audio_ZeroInfinity_v30 (make speaker louder)
ElementalX-HTC10-0.25-Sense (Plus $3.00 EX Kernal Manager Paypal)
Tweaked_pnp_thermal_ivicask_v19

I've rooted my HTC 10 using sunshine. I'm currently on Leedroid's ROM.
As anyone successfully restored to stock? I need to do so to unlock. I want to use a different SIM.

There was a bell ruu somewhere around. Just run that and you'll be back to full stock.

Do you have a link?

No but @xunholyx might be able to help

I have the 2.41.666.3 RUU. You can download it here.

Thanks a lot. I also need a stock recovery. Is it included?

Yes. RUUs always contain the stock recovery. They restore everything to stock. Also, it will wipe your phone, so backup anything you don't want to lose.

Verizon to US Unlocked Questions

I've been reading around and mostly want to know everything for this for that time when CM becomes stable.
Anyways:
Do you lose Verizon network functionality? By this I really mean, calls, SMS, SMS, voice mail, and 4G LTE.
When converted...just act like it's the US unlocked model when flashing ROMs? Do I need to flash the Verizon radio?
I'm confused...and the final question..
To convert it requires a SuperCID and then RUU flash, right? I've seen Sprint owners do it and one Verizon owner, but the instructions were all very unclear to me.
Thanks!
Answers are on post #4, tested it out after being sure of how to do this. If you're lazy, click here...

I've converted my VZW branded 10 to U.S Unlocked. I am NOT using the phone on Verizon network, so I can only answer part of your questions.
To convert, I changed my cid to SuperCID (22222222) and flashed the latest stock RUU.exe from HTC.com for U.S Unlocked. Pretty simple.
I can't tell you if the phone would work on Verizon network, but I would assume it would with a radio flash to get the basic things you mentioned working, as outlined in:
http://forum.xda-developers.com/verizon-htc-10/how-to/vzw-how-to-unlocked-model-vzw-t3376743
Haven't yet flashed any non-stock roms, but I can't imagine why this would be a problem. Also the CM thread has some people who flashed the Unlocked firmware on a VZW phone and got CM working.

I haven't and probably will never try, but I see advanced feature breaking after you do this like wifi calling and the like. but ive also heard all that's different is the radio. but theres different settings unlocked and hidden between the two that may give issues also.
so just give it a shot if you really want. the worst that would happen is you would need to switch back to Verizon firmware.

Tested it out...

Changed my CID to SuperCID (22222222).
Got the latest Unlocked U.S. FW from the HTC Dev site (RUU EXE) and flashed it.
Flashed a Verizon radio in fastboot. (The same one used to make the actual U.S. Unlocked variant work on Verizon)
Flashed TWRP in fastboot.
Formatted my data.
It booted without issue.
Followed this guide (though, on initial boot it showed 4GLTE active BUT no bars (line through them).
After following the guide, I rebooted.
Testing functions:
Calls: Functional and no delays.
SMS: Functional and fast.
MMS: Functional and fast.
Data connection: Functional.
Behavior after reboot: Starts again with the bars crossed off, eventually comes up and working though. Works after that, calls too. Takes about 45 seconds to connect.
Thing to note: It seems as if my signal strength is lessened. Though, this could easily be placebo, weather, etc. It's 1:31AM and I've never paid attention to it before.
Network comes up as 3107 instead of Verizon Wireless.
HTC software updates seem to be broken, it gives a corrupted error. I'm locked/S-OFF, so dunno.
Final deduction: It seems to functional and all, without hiccup most likely. It takes longer to connect than the stock VZW FW does of course, but after the boot it seems fine.
I'm done testing this for now, but if anyone is wondering yeah go for a it. It seems to be fine besides a slower initial connection. Excited for CM to become stable, then I'll play with this some more.

I was the guinea pig for this in regards to Sprint, but you've seem to partially answer a question I had.
I know that the Verizon and US Unlocked use the same model ID, but the Sprint and internal do not. Leaves me wondering if I could just run the RUU for my Sprint phone.

Does your volte work ? Something you can try is flash Viper10 and select as a verizon model instead of the unlocked version, this will add get you on global mode and I think will fix your signal issues. You list your on Viper10 just dirty flash it again selecting verizon version and give it a try. If it does not help you can always just dirty flash again and go back selecting the unlocked version. Just do a back up before doing this and you will covered if you just want to restore the back up. From my experience this might help just do not try running a custom kernel for the verizon version if you converted to the unlocked as your camera may not work and keep forcing close but you can run a custom kernel for the unlocked if you converted to unlocked. My recommendation would be to run the Elite kernel as I have had really good luck with the Elite kernel on the Htc 10 and I think theirs is what I run well on my Motorola nexus 6 also.

Ariac, regarding OTA software updates on the phone, I think you get that "corrupt" message because you flashed a different radio and twrp. Might be worth flashing the original Unlocked radio/recovery back and see if it at least detects the latest update. If it does, you'll also need to remove superCID to be able to take the update.
I reflashed the RUU yesterday, removed superCID and I was able to take the OTA.

HTC One M8 carrier/signal problem after stock rom install

Hi there.
I've got a SH Htc One M8 from someone. All that i know about the phone is that it had Android 4.4.4 version when i got it. I managed to upgrade the software to 5.1. But I read that Htc One M8 can be upgraded to 6.0 version. I couldn't do it (software is up to date message), so i went to a service and asked then to do it. After i got it back, i saw that when i start the phone, a Sprint logo is showing which was something new. After some time i found here updates to 7.1 (crdroid, aosp or aokp....) and they worked fine. (didn't notice the signal problem). But i love very much Sense Home so i wanted to get back to 6.0 stock version. I didn't knew anything about CID, MID, hboot then... After some reading, i managed to install 6.0 version with CID from Sprint. The problem is that my phone is LTE capable (should work over 4G network) but as i can see, it works only with GSM/UMTS Only (I still don't know if i got these right)... Also, I was traveling from Romania to Holland and in Holland i was able to make phone calls but i wasn't able to use mobile data as i could in Romania. Everything works fine if I insert SIM in another phone from Holland so its not the SIM/Carrier. All settings are ok in the HTC (roaming, data in roaming...) so the phone is ok. I out of ideas. I don't know the original CID and MID. The charger that came with this phone was english. Any ideas?

So what you are saying, is that you can't get LTE (4G), but you aren't sure whether you had 4G on the custom ROMs (CRDroid, AOSP, etc.) or not?

Well, i wrote a lot of details.... The issue is that i couldnt use mobile internet in other european country. And i dont understand why i cant use LTA/CDMA network mode nowhere even if my phone is capable. Could it be the Sprint OS?

I remember having a similar issue and ended up reverting back to sense os myself

After i got it back, i saw that when i start the phone, a Sprint logo is showing which was something new. After some time i found here updates to 7.1 (crdroid, aosp or aokp....) and they worked fine. (didn't notice the signal problem). But i love very much Sense Home so i wanted to get back to 6.0 stock version. I didn't knew anything about CID, MID, hboot then... After some reading, i managed to install 6.0 version with CID from Sprint. The problem is that my phone is LTE capable (should work over 4G network) but as i can see, it works only with GSM/UMTS Only (I still don't know if i got these right)... Also, I was traveling from Romania to Holland and in Holland i was able to make phone calls but i wasn't able to use mobile data as i could in Romania. Everything works fine if I insert SIM in another phone from Holland so its not the SIM/Carrier. All settings are ok in the HTC (roaming, data in roaming...) so the phone is ok. I out of ideas. I don't know the original CID and MID. The charger that came with this phone was english. Any ideas?

Try searching for Network Operators, and then create a new APN: T-Mobile US, fast.t-mobile.com, with APN type: default,supl,mms. I deleted and recreated the APN and my mobile data started working again. Creating new seems to work better for me than the default after reset.
