Free Unlocking Tutorial

The HTC One Sim Unlock Helper will allow you to unlock your phone for free with ease. Otherwise you will need to manually perform the phone unlock using commands via terminal emulator on your phone.

You’ll need to use the app root explorer to find and rename HTCOMADM_SPCS.apk and HTCOMADM_SPCS.odex. You want to rename these files something different so that you can replace them temporarily. Also make sure that you keep a backup of these files that you rename, just in case.

After you have rename these files copy the HtcOMADM_SPCS.apk file that is attached to this unlock tutorial. You’ll need to copy this file the same directory (/system/app) making sure to set the permissions to rw-r-r. After you have done this, you should go ahead and reboot the phone.

It may say that the ACC one device check failed, if it does click on the three dots and click on display sim unlock log. Now if you hit the back button, it should say that your phone has been verified. After this, you may hit start and go to the bottom and click on simlock.
