The HTC One M8 is, despite its shortcomings, still a beast. Sure, the fact that its supposedly megapixel myth-busting rear camera once again disappoints is a bit of a downer, but with beautiful design, an incredible display and a generally fluid Android (and now Windows Phone) experience offered, it’s up there with the best. If you happen to own one and would like to unlock it, you’ll be pleased to know that the process is relatively hassle-free, and moreover, can be repeated on a fleet of other HTC smartphones. Below, we’ve got the guide.

It’s worth noting right off the bat that this is a SIM unlock. So once you follow the steps outlined in the tutorial, you’ll be able to use your beloved device with just about any other carrier on the same network. Pretty cool, huh?

Prerequisites

With the formalities out of the way, let’s get started.

Step 1: First and foremost, you’ll need to gain S-OFF using the firewater S-OFF software located at: firewater-soff.com

Step 2: Now, head over to SIEEMPI (here), enter the required details including IMEI and email, and once you have done so, you’ll be mailed a unique file specific to your particular device. Download it.

Step 3: Place the downloaded config.dat file into your microSD card’s /root folder.

Step 4: Press and hold Power + Volume Down to boot in bootloader mode.

Step 5: Using your volume toggle, scroll to the SIMLock feature, then press the Power button.

Step 6: Once the config.dat file downloaded in Step 2/3 has been applied, simply follow the on-screen steps, and after a short wait, your device should be SIM unlocked.

Once you’ve followed the guide, check that the magic has happened by placing another SIM into your handset.
