The HTC Desire HD has received a custom ROM that will flash the Android 4.2 Jelly Bean firmware on it. Use this tutorial only if you're an advanced user as this is not a final release and you might still find some bugs and errors.

This ROM has been bundled by AceofSpades90, an XDA developer, and it is a preview build of Android 4.2. It isn't a final release and currently the following functions are not fully working: Data, Phone, Internal Storage, Tether, Mount Ext SD to PC, Settings > Storage FC. However, the following functions are working: GPS, Bluetooth, Wifi, Logcat, Sound, Surface flinger, Media Scanner, Touch, GPS, Camera. Tell us in comments if you find any other faulty features.

Read the preparation guide below to learn what you need to do in order to get this ROM on your Desire HD smartphone:
