HTC One at&t with Cyanogenmod

Hello all.
I have the Cyanogenmod 11 on my HTC One M7 at&t. It was installed via the cyanogenmod installer and as I checked, my bootloader is unlocked now. So, can I use this guide to change MID and write an original International firmware?
Thanks in advance!

For sure your bootloader is unlocked if you have custom rom.
Thing you need to get your cid and mid changed is "S off"
There are guide in first post or you can search on forum.
That depends on what bootloader do you have.
Give us some more info so we can be specific

Thanks for your quick response!
This information I see in my bootloader:

***TAMPERED***
***UNLOCKED***
M7_UL PVT SHIP S-ON RH
HBOOT-1.55.0000

So, yes I need to do a S-OFF and it will be done by firewater (I hope so :) ). However, before starting I should be absolutely certain that I can use this guide.

OK! I have done the S-OFF on my HTC One at&t (hboot 1.55.0000) via firewater without any issues! So now I am trying to change MID and CID...

I dont know what is your attention but,
1. if you just want to use custom roms you do not need MID changed - just do SuperCID
2. If you want to get different updates you need MID changed
3. You can use HTC One tool for changing CID if you are SOFF

here is tutorial from first post from point of changing MID, If you are not familiar with adb and command lines DO NOT GO THERE !!!
4. Next we will need to change the MID, please follow the instructions carefully. I have already create the proper zip and modified the android-info.txt file to what it needs to be and added it to the att-stanrd.zip or rogers.zip (Thanks to Patrick) which is included as part of the HTCONE.zip file.
a. Type the following commands
Code:
adb reboot bootloader **if you are already in bootloader mode, skip this step
fastboot oem rebootRUU
fastboot flash zip att-standard.zip or rogers.zip
b. At this point the HTC One will get stuck at about 3/4 completed. Please reboot your phone and now you should see the gray HTC one logo or the screen will be gray, continue to next step.
Code:
fastboot oem writemid PN0710000 **Should receive success message
fastboot oem writecid HTC__001 **Should receive success message
Thanks to Link: http://forum.xda-developers.com/show....php?t=2322820


5. This is where I had my heart attack, after following those instructions I was no longer able to bootup my phone and when I tried to reboot it, it would just shutdown and not show anything on the screen. It turns out you need to power on the phone each time it turns off and goes black.


6. Startup the phone (unless you are already in fastboot mode) so you are back in fastboot mode and execute the command below.
Code:
fastboot getvar all
You should now see that your CID, MID and Main-Version have changed to as follows:
Code:
version-main: ATT: 1.26.502.12 / Rogers: Will add soon
modelid: PN0710000
cidnum: HTC__001
Thanks to link which has a good breakdown on the difference MID versions for the HTC One http://forum.xda-developers.com/show....php?t=2223236

Ooops! I have a problem... I can't change CID! This command "fastboot oem writecid HTC__001" returns OK but does nothing! My CID is still CWS__001. What is wrong? Please help!

Fuf! OK. I have changed the CID to HTC__001! "get var" command shows new CID after rebooting. So, now with this "International" CID can I get an OTA update? I know about LTE but it is not necessary for me.

I have answered on my question! Yes, it works like a charm! OTA update comes without any issues!

Hello, guys. Today i just bought HTC One M8 T-mobile version. I'm sorry for the stupid question, but I want to do the same with the M8, to change T-mobile Radio to International One M8. Back in my country I need "HSDPA / GSM 850/900/1800/1900" , but the T-mobile Bands are " LTE, UMTS Band IV (1700/2100); (AWS A-F) , UMTS Band V (850); UMTS Band II (1900); Quad Band GSM "

If I transform the T-mobile M8 into Google Play Edition M8, is this will change the radio?

What treat I have to use to make that possible?

Thank you in advance

The supported radio bands are almost the same between the GPe and T-Mobile, with T-Mobile have two extra bands.

I converted an AT&T model to EU international and I'm having issues with data. I compared my phone's *#*#4636#*#* setting with my roommate's M7 and in the select radio band option I get automatic and USA band while he only gets automatic. Any suggestions?

Can I use this guide for Android lollipop 5.0.2 to convert At&t model into international ?
Edit.1:
OK, I converted the Att model into International, Changed the CID to SuperCID, it works flawless, everything works fine, just one weird problem, I can't understand.
After few minutes, it keep Shutdown itself, even if on charger, eventhough it shows 90% Battery level.
I flash different ROM (European/Asian) but it keep shutting down.
Can anyone Help or point me the right direction.
Edit.2:
It works on Extreme power saving mode for more than few minutes. but still, it shutdown it self after 1 hour.
One more thing, it won't shutdown in bootloader or TWRP mode.
