Moderator Edit: The procedure in this guide may be outdated and we have reports of it not working on newer devices and causing other SIM unlock exploits to fail. A few mentioned that it caused all SIM cards not to work. Proceed at your own risk! (I recommend against it.)
Hello guys,
Here is a method (confirmed working by Me) to SIM Unlock your HTC ONE M8 GSM ONLY NOT FOR SPRINT for other SIM cards for use on other GSM networks.
Before we begin I wish to inform you that I did not create this tool. It is the property of sieempi.
You MUST be S-OFF & have External SD for this to work.
S-OFF METHOD or http://theroot.ninja/ if you can't S-OFF with first method
Usual disclaimer: I am not responsible for anything you do to your phone. Use this mod at your own risk.
as pointed by @GSLEON3 you could only do the SuperCid "11111111" described bellow after S-OFF and it will also unlock your device but if for some reason you change back your CID you will lose the unlock the other method unlock the device forever
SUPER CID WILL NOT SIM UNLOCK YOU DEVICE FROM CARRIER
how to SuperCID your device after S-OFF
[NOOBS Guide] HTC ONE SUPERCID method via fastboot
or permanent method
Instructions:
1) Go to this site: http://www.sieempi.eu/blog/2011/09/22/universal-sim-unlock-for-s-offed-htc-devices-536
2) You'll notice that the HTC ONE M8 is not listed in the supported devices, but the process does work.
3) Supply a valid IMEI and email address on the form on that page and where it says "Phone Type" put HTC ONE M8 , and they will email you a Config.Dat file to put on the root of your EXTERNAL SD card.
4) Reboot into bootloader, select "SIMLock" and it'll apply the config file.
5) Follow the instructions on the phone and reboot when it tells you to. If you get an "OpenCID File Fail" error, this is normal, proceed anyway!
6) Once you've rebooted, your HTC One M8 should be fully SIM Unlocked!
7) Put in a foreign SIM card and test it out
8) for Sprint M8 devices only Thanks to @pisang_azafor pointing and @nikme for the original thread follow this instructions http://xdaforums.com/showthread.php?t=2682242
