Fully Convert Your GSM HTC One M8 into a Google Play Edition

Just a few days ago, XDA Forum Moderator graffixnyc showed us how to run the Google Play edition firmware on the standard model HTC One (M8). But while this allowed us to enjoy many of the GPe device’s software, it wasn’t exactly a full conversion. Now, thanks to S-Off being achieved by the Firewater team, graffixnyc has released an RUU to completely transform your vanilla HTC One M8 into a  GPe device.

Before doing anything, you’re strongly suggested to backup everything on your device, including its internal SD card, as the contents will be wiped in the process. Next, you must obtain S-Off using the previously covered Firewater S-Off method. Then, download the RUU zip, execute a few ADB and fastboot commands, reboot, and you’re good to go. After the process is complete, you can choose to flash a custom recovery, but this will make it so that you can’t install GPe OTA updates directly.

Please keep in mind that this method only works for GSM variants of the device. And as mentioned above, please be sure to backup all of your data before getting started.

If you wish to completely convert your standard edition GSM HTC One M8 to a Google Play edition, head over to the original thread, read all of the steps thoroughly, and give it a shot.
