How do I Unroot and S-ON an HTC One M8

A friend has an AT&T HTC One (M8) and went down the S-OFF and root path without getting the preliminary backup files needed to go back to stock. Low and behold, there was an issue and he needed to return it for warranty service. Fortunately, this is a fairly straight forward process to do and the steps needed to unroot and S-On the HTC One (M8) back to stock are below. While these are specifically for the AT&T model, the steps are applicable to all HTC One M8 models.

How do I Fix Tethering on the HTC One M8

I’ve been using a T-Mobile SIM card in both an AT&T and Verizon HTC One M8 for the past few weeks on their stock (but rooted) firmware. While both handsets are unlocked for use with GSM carriers, HTC’s implementation of APN and entitlement checks make it problematic at best to use all the features available. For example, MMS does not work on either device, regardless of APN settings, and attempting to tether invokes HTC’s Tethering Guard app to check if tethering is included as part of your data plan. This is fine if you have a tethering plan on the original carrier, but when using another carrier’s SIM card, the check fails. Turns out, the fix is a simple text edit of one of the carrier customization files found in the system folder.

I started doing this a few years ago with my HTC One S using HTC’s proprietary HD Media Link. When the Google Chromecast was announced last year, I got really excited that could use my Nexus 7, or even my laptop, to stream videos and grabbed one from Best Buy when they launched.

How do I Take a Screenshot on a Chromebook?

One of the things I do a lot of is take screenshots, and one question I keep seeing asked over and over is, “How do you take a screenshot on a Chromebook?” If you’re like me, you probably didn’t read the instructions when you first fired up that Chromebook and only gave the welcome window a cursory glance. That’s why you’re here.
