Turn Your HTC One into a Google Play Edition
Just yesterday, we covered how Google had finally decided to update the HTC One Google Play edition to Android 4.4 KitKat. We say “finally” because HTC had stated that the update was ready ten days earlier on their official Twitter account.
Regardless of timing, the update is a good thing—even if the Verizon, T-Mobile, and AT&T variants of the OEM-skinned Moto X managed to receive their updates before either of the two Google Play edition devices. But up until now, this only helped the few who actually purchased the Google Play edition devices. Now thanks to a guide by XDA Forum Moderator and Recognized Developer graffixnyc, you can essentially turn your standard HTC One into an HTC One Google Play edition.
We’re not going to lie to you. This is going to be a somewhat complicated process, and it’s not meant for the faint of heart. As such, you need to already be S-Off. You also need to have a working knowledge of ADB and Fastboot. And as stated in the OP, “This procedure is not easy and is not really noob friendly, well flashing the RUU is not really difficult but it’s the prerequisites that are more complex/risky.” In other words, proceed with caution. And if you’re confused, it’s best to turn around and walk away slowly.
Make your way over to the original thread to get started. Just please do yourself a favor and read through the entire OP and make sure you know what you are doing before getting started. Nobody likes ending up with a paperweight.
