How-To: Install KingKobra 4.2.2 On A HTC Sensation XL

HTC Sensation XL KingKobra 4.2.2

As the HTC Sense 5 is only being made available for devices that were released in 2012, owners of the HTC Sensation XL will be getting updates because there are none available for Android 4.1 Jelly Bean or above.

Developers at XDA have developed a ROM for the HTC Sensation XL which can be used to give XL users a taste of Sense 5 and Android Jelly Bean 4.2.2.  And in this guide, we’re going to show you how to install it.

The KingKobra 4.2.2 ROM can be installed on the HTC Sensation XL, but before we do so, make sure of the following:

  • This particular tutorial is only for HTC 4.2.2+Sense 4 on HTC Sensation XL.
  • Your device is rooted and you’ve installed the latest TWRP or CWM Recovery on it.
  • You have enabled USB debugging.
  • You have charged your device so its battery level is 85 percent or more.
  • Now you can use this with S-Off and S-On devices. However, if you are in S-On, your going to need to flash boot.img separately.
  • Enable USB debugging on your device by going to Settings>Developer options> USB debugging.
  • Have ADB and Fastboot drivers configured on your PC?

Note: The methods needed to flash custom recoveries, ROMs and to root your phone can result in bricking your device. Rooting your device will also void the warranty and it will no longer be eligible for free device services from manufacturers or warranty providers. Be responsible and keep these in mind before you decide to proceed on your own responsibility. In case a mishap occurs, we or the device manufacturers should never be held responsible.
