I think the latest sim unlock is for Lollipop.

Is there anyway to downgrade Lollipop?

I am also in the same boat with OP, I have a Sprint HTC One M8 Harmon/Kardon with Marshmallow 6.20.654.3. I live overseas and i need to get this phone sim-unlocked. Can this be done with the current software version or do I need to downgrade the ROM to be able to sim-unlock my phone for use with an international GSM-Network?

No changing the ROM will not SIM unlock it. Did you mean a Verizon Droid Incredible 2?
No ... Incredible S locked for Virgin Mobile

You either need to contact the carrier for the unlock code or use one of the pay services and purchase an unlock code.
Which HBOOT version does the phone have? If it is version 1.09 you might check the Development section. There was an older thread that claimed to S-Off and SuperCID earlier versions but doesn't work on the newer versions.

The post pretty much explains what you should do. If you are S-ON, you have to be S-OFF to downgrade you version. If S-OFF, you can downgrade by using a lower RUU. The post explains it pretty well.

Unable to Sim Unlock some Sprint M8's ?

Hey there!
SO I'm just about to buy myself a M8 or Iphone 5 ( If No option ) For what I have read on this forum from yesterday seems like some Sprint M8's can't be unlocked ? The posts I read was from April maybe the Bad A$$ people might have fixed it already ? Please enlighten me on this I prefer the HTC one M8 but the second option is the Iphone 5... I've used a M7 that was ATT as my last phone I Unlocked that Via a Unlock code from a website for 15$ And I don't live in the USA I live in Sri Lanka :fingers-crossed:
Thanks in advance have a good day.
Little hope for sprint ones.
You can download a file and flash it on the bootloader via the Sim Unlock option, but as much as i know it only worked for AT&T and T Mobile. You could give it a try though but i think theres a Risk of a brick

Bump ! help a bro out
I haven't heard anything about people not being able to SIM unlock the Sprint M8. The only issue I have heard about is that some cannot get S-Off without Sunshine (Which costs $25). There are several posts on this forum regarding SIM unlock. I have done it twice now and both times I was not in the US and thus not on Sprint's network. One time in Malaysia and one time in Costa Rica. The simplest is to install BadBoyz HK rom and then use the unlock method in their post. The unlock took about 5 minutes. You may need to enable other frequency bands on the phone, but that wasn't difficult either and there is a post in the general forum about how to do that.
how are you sim unlocking your sprint m8?
use bad boyz method, it works
but make sure you'r on bad boyz rom when you do the sim unlock, wont work with stock rom. after then sim unlock, you can go back to stock rom if you want to.
no need for s-off to sim unlock

I was also wondering about this too
I was able to unlock this for T-Mobile on Android 5.0.2 (lollipop) , HTC sense 6.0 and Hboot 1.61. I think the key was downgrading the radio.
http://forum.xda-developers.com/showpost.php?p=60417817&postcount=12 Check that post and follow it, that worked for me with S-ON

If you hit a brick wall unlocking the phone for yourself, the easiest solution is to buy an unlock code from a third party and call it a day. I always use https://www.unlockbase.com/unlock-phone/htc/ when I decide to buy an unlock.

Had kind of the same problem, upgraded to lollipop, being outside of US, could activate my device on GSM.
So after unlockign the device, with S-ON, I flashed the ViperOne 9.0.0.
Now the phone just flies. Works on any GSM network.
