Is it possible to change the radio for HTC One M8 from Sprint HK to International?

Hi,
I have inactivated Sprint HTC One M8 Harman Kardan and I unlocked, S-Off, change it to super CID and rooted it but still I could not unlock the sim card ( I tried the 2 methods to SIM unlocked but no success). Even when I install ROM I'm still getting the activating message.
Is it possible to change the radio or any other file to turn it from Sprint locked to international unlocked HTC One M8?
I know I made a mistake by buying it instead of the unlocked version but what has happened has happened.
Please help.
Thanks in advance.

Anyone?

Converting AT&T M8 to T-Mobile M8

Hi All!
Just returning to the world of flashing after being with Verizon for so long. I have recently switched to T-Mobile, and have been using my unlocked AT&T. Other than S-Off and an unlocked bootloader I haven't looked too much into flashing yet.
I have been reading the forums and it seems as though the GSM version of the HTC M8 are relatively interchangeable. This got me thinking, I am able to make the necessary changes to CID & MID to match the T-Mobile version, and then convert using a T-Mobile RUU?
Thanks!

Thank you! Just wanted to confirm - that is the exact thread I reviewed.

Just do supercid and use tmo ruu.

Wait... so I just need to switch the CID to the "supercid" and I don't worry about the MID and just flash the Tmo RUU?
(it's been a LONG time since I've been on a HTC device...)

Not the OP, but I am not quite sure of the steps I would need to take to return from 5.0.1 GPE to stock. Could you help me out? Thanks!

Is this process workable to from AT&T to DEV version of M8?

So I was browsing the HTC website and came upon this webpage with various ROMs for the HTC m8 and others:
http://www.htc.com/us/support/rom-downloads.html#unlocked
I have an AT&T Unlocked Bootloader and rooted M8 but it's still S-ON.
Can I basically change the CID to the DEV version and then flash this rom/RUU over the M8 to get the developer version?

You need S-OFF to change your CID. So that is your first goal here.
And Sunshine is your only chance to s-off. ?

Thanks Darth,
Did exactly that...sunshine to s-off, changed the cid to supercid and flashed the Dev Edition RUU to get what I wanted. I noticed that you can't use fastboot boot recovery.img with that RUU but I flashed a custom recovery and then back to stock and everything is great now.

Back to STOCK tmobile M8 with supercid and S Off

I need to get back to stock and wanted to make sure I am doing this the easiest way so I dont brick my phone. I have a TMobile M8 with supercid (cid-11111) and S Off. I currently have skydragon gpe rom installed with latest firmware 4.x firmware. Do i need to Relock bootloader and change cid back to tmob cid? then use which ruu to get back to stock. Sorry guys, been pressed for time and did as much searching as i could,
I appreciate any help thanks.

it worked
I relocked bootloader and set cid back to tmobile cid then used ruu directly from tmobile. It worked thanks anyways everyone.
