[Q] Issue with Vodafone EU HTC ONE on T-Mobile US network

I have a vodafone EU HTC ONE phone.
I have now moved to the US and am on T-Mobile.
However I can't get 4G/LTE on the phone no matter what I try (I've manually entered the fast apn)
Does anyone know if this is even possible?
Do I need to unlock the Bootloader, etc flash with the T-Mobile ROM, etc. ? Will this even work?

The US uses different LTE bands to EU, so no, it won't work. That's why there are region/carrier specific devices.

[Q] Using 4G on Sprint HTC One when GSM is enabled

Hello,
I recently acquired from ebay a used Sprint HTC One M7 for cheap because the guy couldn't unlock it.
I followed all the tutorials and guides here, and got the phone unlocked, TWRP recovery and SuperSU flashed, S-OFF, and a custom rom (Viper) flashed on it successfully.
I am from France and my network operator is Free.fr. I used both the *#*#4636#*#* and the Mobile settings to enable GSM and the phone, SMS, and 3G data are all working properly.
However, my operator allows for 4G LTE as well and I would like to use it if possible, while retaining the use of the Phone itself (making calls, texts etc).
The way it works for Free.fr is that I have to login on their website, and enable 4G manually. The server will then check if my phone has 4G LTE compatibility and enable it if it does, but everytime I try it tells me my phone is not 4G ready.
Is there anyway to do this? A guide or tutorial out there perhaps?
edit: more info:
It seems I need 2600 MHz frequency for 4G to work with my operator, could it be that the Sprint version cannot handle this? Any solutions?

Yeah :/ the Sprint HTC One only supports the 1900MHz for LTE. There aren't any solutions afaik, unless you might want to do a hardware mod, and doing hardware mods on an One is near-impossible.. so you're out of luck.

Ah well, that's alright, at the price I got it for it's still worth it even without 4G. Thanks for the reply!

Hi, could you share your experience of sim unlock the device?
my phone is on 1.57 hboot. I s-off it and RUU to 1.19 firmware. Android 4.1.2. Then I install latest TWRP and Super SU 2.0
Then I download the "sprint htc one sim unlock helper" , select sim unlock.
phone reboot. select " GSM/WCDMA/LTE auto" in *#*#4636#*#*"
Now when I insert my AT&T sim card. it pop up to select carreir, I choose "AT&T", I also choose "GSMUMTS only" in network moode. Also set up ATT APN.
now iin Phone indentity, I could see my phone number,
But there is no signal for the phone at all...
Could you told me your way of doing the sim unlock? Thanks.

I did exactly what you did and I had signal. I am from France so I don't know about AT&T though. With my French operator it works fine now.

[Q]Network locked or not?

My Htc M7 is s-off,supercid,unlocked bootloader,root,custom twrp recovery....When i bought M7 it was full stock,and with locked network.I unlocked everything,and i flash Config.dat that gets me acces to my network...
That was two years ago,i flashed lots of roms and kernels and firmwares and RUU 's thru that time.
Lately i notices drops in my network state,ofkors while i was tracking unusual battery drains.While in most custom roms,APN's are configured automaticaly,in some they are not.So,i noticed that my phone can acces network without any APN configured or any APN's in the setting list.
Here is a picture where some app from playstore says that my network is locked(i dont know what this means),but without APN configured i run Tele2 sim and have Tele2 signal.
Is this ok,or maybe some RUU's that i flashed in the past turn my "unlock" state to "locked" state?

You would get an invalid sim error if you were not unlocked

Thanks i wasnt sure about this,its not mentioned anywhere if Config.dat can be reseted or deleted by Ruu or anything,and if maybe "unlocked" state can be lost or broken by accident,or partialy lost or broken...thanks again

[Q] Sprint M7 was previously on Tmob, Trying to flash back to Sprint, now no service.

Hopefully someone can give me some guidance. I bought a phone locally from a facebook classified group. It has a clean ESN and said "ready for activation" on sprints network when checked. The phone has been unlocked and it used on a different network, but was supposed to be flashed back and ready for me to activate with sprint, and all I'd have to do is pop in the Sim card for 4g and activate it.
The phone has no signal at all, so even though I can activate it online through my account, obviously I can not use it. I'm afraid that when it comes to this end of android, I know just enough to get myself in trouble, but not enough to fix my problem on my own!
Here is where I stand.
-Phone MID was changed by seller to Tmobile MID, I had to change it back to sprint MID so I could flash firmware and RUU.
-When read with QPST or CDMA workshop, phone is NV only, not RUIM, which is as it should be.
-Once RUUed, the phone has no service. It is unactivated, but usually an unactivated phone will still show signal. It has a x over the bars. This does not change if I change any settings in *#*#4636#*#*
-I flashed a custom rom (lollipop nocturnal edition) so I could get access to the APN settings. Once the rom was loaded, all I had to do was set roaming options to automatic, and my phone showed signal, albeit it now thinks it is roaming all the time I set up the sprint APN in APN menu anyways, just to make sure it was in there. Phone still shows roaming. PRL = 1
-When I restore back to the image made immediately after RUU, no signal again. PRL shows as a sprint PRL 55xxx. I can't update profile or PRL even on wifi.
MEID MSID MDN and IMEI all appear to be good.
Android Version 5.0.2
Baseband 1.01.20.1225
Kernel 3.4.10
Build LRX22C.H3
I have access to QPST and the free version of CDMA workshop. Phone is DIAG enabled, rooted, TWRP recovery, @ off and unlocked
hboot 1.60.000
os 6.16.651.2
TIA for any help anyone can give.

What about using ruu?

Is there any custom Rom for HTC M8 sprint which has the option to choose Automatic radio bands? Please anyone share any solution.

I have flashed the stock RUU, please provide more details about dfs and how to enable all 3g bands? I'm looking forward to you.

Try this!
1) Put your phone in LTE/CDMA network mode
2) Dial ##786#. It will open the EPST menu.
3) Select Edit mode and put 000000as the MSL/password.
4) from the Options menu, select reset settings.
please note that this will also factory reset your phone as well as the radio settings and you should be able to get the signal after restarting and putting the phone in GSM/UMTS mode again (if not already).
To enable all 3G bands, follow this post:
