Cheers HTC One users! You can now finally boot the Android L developer preview build (that Google released for selected Nexus devices only) on your HTC One M7, all thanks to XDA member ssrij and others who had been of great help in making this possible.

Getting Android L on HTC One wasn’t easy, matterfact, it’s the first non-nexus device to get the Android L port. And so naturally, there is a huge list of issues with this Android L port for HTC One that it’s nowhere near to be used as daily driver.

Also, HTC One being a non-Nexus device, things may not get solved out quickly. Even this Alpha release has come after 2 weeks of official announcement of Android L, which is opposite of the rapid influx of custom ROMs that we generally see for various Android devices whenever Google releases a new version of Android. So sorting out the incompatibility issues on Android L for HTC One may not go easy.

What’s not working on the HTC ONE Android L port

List as of 12/07/2014.

  • Camera
  • Wifi
  • Bluetooth
  • Cellular data
  • Sound
  • Sensors

This HTC One Android L ROM is based on Android L developer preview factory images that Google released for Nexus 5 and Nexus 7 2013. So you won’t have to install gapps separately with this ROM. Just go ahead and download the Android L ROM for HTC One and flash on your phone using a custom recovery.
